Pixel 5 battery drain overnight
2
Got a Pixel 5 about a week ago. The phone seems to lose quite a lot of battery while being idle overnight, and there is no particular app/service that seems to be driving this. Is this defective hardware or can this be fixed by me? For context, the I'd charged to 100% (where the graph below begins), then used the phone a little (which is where the first inflection point is), then slept with no apps running in the background (which is when the battery dropped by a concerning amount), and then you see the inflection point when I woke up and started using the phone again in the morning.

I am noticing the same issue! Mine drops to about 75% overnight from a full charge.

i'm having the exact same problem.
charged my phone up to 100%, took it off charge and went to bed.
Woke up this morning 8 hours later, and despite the screen being off all that time and it just sat there idle, it was down to 67%.
No app was hogging the battery, i've tried rebooting the phone, i even tried a full factory reset yesterday morning.
i'm still having unacceptable battery drain whilst the phone is idle.
I have no idea if i need to get my phone replaced, or wait for a software update?

That is quite a bit more battery drain that you should be seeing from letting the phone sit idle overnight.
 
Could you try charging your phone to 100% and then leaving it in safe mode over night to see if it makes a difference to the battery drain? You can boot into safe mode using the instructions located HERE
 
That will help determine if there is some unknown background process causing the drain.

Thanks, I'll try overnight tonight. In the meantime, I've been at work today - where I don't touch my phone often - and my phone's just in regular mode currently, but seems the battery drain is slower now, during the day. Seems strange

Hi, I charged the phone to 100%. Then, left it on normal (non-safe) mode for about 5 hours overnight, and the battery drained down to 86%. Then, I switched to Safe mode (though not on airplane mode, meaning WiFi, Bluetooth and other radios were still on) and in about an hour, the battery drained down to 79%. This is shockingly bad standby time. You can also see there were no processes running at all in the whole time. What is going on?

Similar problem here with Pixel 5 which just started over the last day/night. Woke up this morning and the phone battery was dead, even though it had 40% the night before. Luckily I have a backup alarm, but shouldn't have to guess if my phone is going to be alive in the morning. Haven't installed anything new over the last couple of days. Restarted this morning and it seems to be working fine again for now, but not happy knowing that I might wake up to a dead phone until I can figure out what's causing this.

EDIT: Today appears to be normal for now. 3% drain over 3-4 hours standby. I noticed in the play store that there was a few updates yesterday to some Google services... thinking it may be related to that.

Another update: I turned off safe mode, went back to regular mode, but turned the WiFi off (to see if that's what was causing the drain), and the battery still went down from 79% to 73% in about an hour, whilst completely idle. 

That is basically the battery gone from 100% to 73% overnight, with no usage at all. 27% lost!

The phone is barely a week old. I used a Pixel 3XL with the same apps and settings just before this Pixel 5, and that never had the same issues. Do I need a replacement or is this is a software issue?

While in safe mode, did you leave wifi etc disabled? Other users about are advising that with the radios on, they still experienced the drain in Safe Mode.

Leaving it in safe mode seems to decrease the battery drain over night. Went from 95% to 86% I'm around 9 hrs. This is with always on screen ON and wifi enabled.

While waiting for Sam's response, I'd concur that using Safe mode with the radios on still drained the battery down. And again, in the middle of the day, now, the battery seems to consume far less energy. This has been the trend for quite a few days. Quite baffling. Also, similar to Sam, the processes that are listed to be running overnight do not add up to the battery consumed overnight. Is it possible the battery indicator itself is incorrect?

Hi Brian,

when it booted up in safe mode, the phone was in airplane mode, so wifi was off, no 4G/5G signal, bluetooth off, etc and i didn't turn them back on.

additionally, its now been 6 hours since i rebooted the phone back into normal mode, with wifi on, 5G signal, etc, and my battery is now down to 92%, but thats with me watching some youtube, a few trailers on Amazon Prime, screen on time 32 minutes out of that 6 hours.
This already feels an improvement in battery drain!
Will leave it in normal mode tonight to see what battery drain i have when i wake up in the morning.

thanks

I put the phone on Airplane mode (though not on safe mode) overnight, and the battery didn't drain at all overnight. The minute I turned off airplane mode in the morning, the battery level started dropping (quicker than I'd expect). This would lead me to believe all the drop in battery is owed to some radios being used overnight. Any idea how i can identify exactly which radio is creating the issue?

well, another day, and my phone is back to draining battery as per normal when idle.
i had charged my phone to 100%. 
In the last 6 hours, it is now down to 63%, with only 1.5hours screen usage time since full charge.

There's no obvious app draining the battery as per battery usage below.
I'm trying to decide whether to hold out for a software fix, or whether i have a defective phone, and need to arrange for a replacement.

I was having serious battery draining. I moved from a Pixel 2XL and carried over a phone merger where you connect the phones together and transfer everything from the old phone to the new phone. 

For the last week I've been having to put my charger.in at the end of the day at about 8 or 9. I hardly used the phone with about 1hr and a half scree on time during the day.  I was not impressed.

I have managed to fix this, simply.my.entering.safe mode and then turning off adaptive battery, restarting the phone and then turning adaptive battery back on. 

To go into safe mode, press the power button then long press  the restart button on the top right. 

Hope this is helpful.

I did a full factory reset, deleting all my data and starting afresh. The night right after the factory reset, the battery did not drain much overnight, but the next night, it was back to the same severe battery drainage.

Think what we need to know is, is this a hardware issue or a software issue. If a hardware issue, is it an issue with the battery itself, or an issue with some of the radios in the phone? Is there any way to test this and find out?

Installed AccuBattery. When the screen is off, the phone does go into deep sleep for the most part (which should conserve battery). But, even then, with the screen off and in deep sleep, the phone consumes 3.5% of battery per hour, which is frankly ridiculous. Any idea how we can see which processes are running in the background when the screen is off?

 charged my pixel 5 to 99% last night, randomly woke up at 4.30am so i checked the battery down to 82% doing nothing for just over 5 hrs! After this I put it on flight mode and for the next 3-4hrs there was no drain, it stayed at 82%. So there is definitely something wrong here.

I seem to have the same issue as well. While my current 3-year old android phone consumes 1-2%, the new pixel 5 consumes about 30% battery overnight. After the first time I noticed this issue, I did a factory reset and didn't install any apps on it other than the default Google ones. Unfortunately that didn't improve the situation. The battery lasts just about a day on full charge without me using it!
According to Google customer service, the device is performing as it should since it lasted a day. They disregarded the fact that I didn't really use the phone during these 24 hours! Either way, I managed to get a replacement device. It will be interesting to see whether the issue persists.

I am having different issue considering battery, but maybe it will light some sheds of knowledge on this one.

I noticed that my Pixel 5 is not charging properly all the time. When using USB-C 3.1 from PC, the phone is apparently not charging at all (my Pixel 2 was charging super fast from this source) - I am not sure about wattage. Using included Pixel Charger (18W usb-c to usb-c) with original cable, there are some moments when it says it's charging, but the percent is not rising up. It recently happened about 15 minutes ago while charging - the phone stood still at 67%. Restart, unplug and plug [charger] seemd to helped. The phone is charging now and it's now at 90%. I don't know what is it about (hope it's software issue) but it's a pain looking at a phone after 2h and the battery is stuck at XX percent, because of this issue. 

One time I have seen that after restart the battery percentage was back to normal (before restart around 65%, after restart 95%) but it doesn't seem to be that way always (including today).

While charging, the battery is quite hot, I am not sure if this is an issue.

Additional notice is that my battery life is OK. At night it drops for about 5% or less, battery lasts all day.

Is anyone else having such problems? Is Pixel 5 having some battery issues?

So I've determined in my case why the battery drain. It's 5g. I have access to 5g in my area, and it's seems even if I'm connected to wifi it'll still drain lots of battery.  When i turn off 5g and only use 4g the phone battery is a dream!! So i guess I'm no longer going to use 5g anymore, just not worth the battery drain, unless they do some smart data mode like Apple that switches between 4g and 5g to save battery.

The phone will be losing battery even in the safe mode as per my personal experience with the phone. Make sure the location services are off while you sleep, or try keeping your phone in Do Not Disturb or Airplane Mode. I saw significant improvement but still lost 25% from full charge. Might get a software update soon that will fix all this . I hope it helps. Thanks !

I tested this by turning off all radios one by one whilst keeping the others on. Think the only thing I can think conclude is it is cell phone reception that's draining all this battery. But it isn't necessarily 5G. I disabled 5G, but still had almost similar drainage. I've now been sent a replacement device by Google. Will be testing the new Pixel 5 now. If both of them have the same issue, it's quite a safe bet that this is a software issue or Google has made an error with the Pixel 5 battery management

even though my phone is connected on wifi whilst at home. Last night, i changed preferred network from 5G to 4G.

Tested this with the new, replacement device Google sent, and it had the same results. The battery drains overnight, losing about 19% in about 5 hours (which is terrible). Then, I turned off my SIM card connection, but left all other radios on. This then flat-lined the battery consumption (the inflection point you see below). Also, I still have my old device, but it doesn't have a SIM card in it anymore. That old device now doesn't consume much battery. Think it's safe to say that this isn't an isolated issue with one Pixel 5 device. The Pixel 5 in general has bad standby time when it is connected to a cellular network. Can this be fixed with software updates?

Also seeing this in general throughout the day. 8% on idle from 91% to 83% in 2 hours. Lots of this seems to attribute to the ambient mode potentially. My wifi and cell signal have been stable.

Hi there. Just to weigh in on this issue. I too am getting exactly what the original poster is experiencing.

When I first had the P5 it sipped battery overnight at around 2% but since then it has been awful overnight.

 For a 6-7 hour period I am dropping around 20% overnight with no indication on the main battery stats page.

During the day the phone is absolutely fine and idles at a reasonable amount.

I've always found that a bug report generated from developer options can be used to analyse battery stats in more detail. There are some sites you can use to upload these and it will show a detailed graph and associated stats.
 
With that said this is definitely something to do with radios so I am going to try what the original poster said and put my phone in airplane mode tonight to see what happens.

Cheers.

Same issue here, I've had my P5 for a few days now, and my battery drops anywhere from 30%-40% overnight; during the day, it's fine (yesterday, I was out and about for about 3 hours and my battery only dropped about 3% with minimal usage).

Last night I put my phone on airplane mode to see if that would help, and it did, it only went down 10%, much less than the 30%-40% power drain, but 10% still seems like a lot for being on airplane mode.

My previous phone, a Motorola Z Play, didn't have a big power drain like that overnight, it only had about a 1%-3% power drain.

I'm still not sure what is causing the power drain, so far that's the big con for this Pixel 5.

Hi Pulak,

Thanks for letting me know you submitted a bug report to Google. 

I have done some testing the last few nights and these are in line with your observations.

Night #1 - Airplane Mode and Bluetooth off - Started at 52% battery and saw no drain at all in the morning.

Night #2 - Bluetooth off only - Started at 60% battery and woke up 6 hours later with 57% battery. 

I also can concur that my daily standby time is great and the screen on time is as per all the reviews.

I will continue to do some tests over the next few nights and see if I can spot any more patterns worth reporting.

Fingers crossed Google/Android engineers see something in the error logs and observations supplied.

I turned my Bluetooth off last night and my phone used 4% in 8 hours next to me instead of 25%. I think we're honing in on the issue. I have SmartLock on for my Chromebook and a Polar watch connected.

The question is why. I have recently changed from a Pixel 4 XL which had similar usage (i.e. about 0.5% per hour) but with Bluetooth on and these connections also. The only thing that has changed is moving to the Pixel 5. 

I think there must be some issue with the Bluetooth software/hardware of this phone.

I will tonight conduct the same tests over the next two nights, first with Bluetooth and wifi off and then the next night just in good old airplane mode (so all radios - Bluetooth, Wifi and Mobile off)

Hi there,

Last night my phone was in a different room in my house compared to the last few nights.

The result here was interesting to say the least.

With bluetooth turned off and Wifi & various other radios on I noticed a drop from 88% to 73% in about five hours. This was the same configuration I had when the phone was in another room the previous night.

I've sent these log files off to Google/Android teams to see if this is related to phone signal or scanning whilst the phone is meant to be in a deep sleep. Whatever is happening, this phone is not going into a proper deep sleep.

There is an app in the Google Play store by a favourite developer of mine Francisco Franco called 'Naptime' (https://play.google.com/store/apps/details?id=com.franco.doze&hl=en-GB) that i may have to use if this overnight drain does not get resolved by the Android team.

I am going to try disabling all radios again tonight in the same room that my 15% drain occurred just to be sure it is related to radios.

Cheers,

POSSIBLE SOLUTION
=================

As Previous posters have stated, the solution for me was:
  • Settings->Network and Internet->Mobile network->Preferred network type->4G.
Battery life went from terrible to awesome.

It kind of makes sense since my provider has 5G availability showing about 1 mile from my house. So I probably get a very marginal signal and constant handshaking. I have also seen this with earlier phones and marginal 4G signal like I used to have at my workplace.

What is really annoying is that the Battery Usage stats do not show this and hence do not provide any help in diagnosis. There used to be battery apps that would help before security shut them all down. I don't know why Google can't show how much battery the radios are draining.

I have Google One support ticket for this but no response in 3 days ...

Hi Peter Firth 8845,

I'm seeing the drain even with bluetooth off, but only if I've had it turned on in the boot cycle.
It looks like the wakelocks appear the seconds I turn on bluetooth and not disabled till after a reboot.

I'm confident you can't replicate the drain if you turn bluetooth off, reboot your phone and don't turn bluetooth on again.

Hi all,

Update from me. I disabled BT and WiFi last night and my battery consumption was around 9% as opposed to just BT off which I guess is to be expected as WiFi is more efficient than mobile internet. I have in developer options turned off the keep "mobile internet switched on when connected to wifi option" to see if that helps. This flag is turned on by default and is supposed to maintain internet access if your wifi becomes flaky or you move out of range.

@Giles Knap Thanks for posting. I'm not sure it affects everyone as I don't have ready access to 5G. I think even though I have 5g preferred selected, it defaults to 4G anyway. I switched to "4G preferred" but did not notice any noticeable difference.

I have been asked by Google to send a 12-hour device log so tonight I will just keep everything on but tomorrow night I will go to airplane mode just to ensure my issue is in the radio aspect of the device.

First go into the battery usage screen from battery settings using the... Menu. 

Then  hit ... Again and you will see "show full device usage" on my phone the numbers show all radios and screen power consumption and the numbers actually as up to total usage!

@Giles Knap Thanks for your post. I was aware of that. I don't have any obvious issues identified here. I had a Pixel 4 XL in exactly the same setup and did not have any issues like this. It had very good battery management when screen off, unlike this Pixel 5. Besides my battery usage with just 4G was better than in full radio mode.

I did a 'normal' night last night with all radios on and it was back to using around 2.5-3.0% per hour whilst I was asleep. However, I've also noticed that my usage graph profile is a very regular constant decline and does not adjust much as to whether the device is in use or not daytime or nighttime. Normally when the device is not in use, the graph line flattens out horizontally considerably. I have done a factory reset and it makes not difference.

I'm sending the bug reports to Google today.

Hi Dan Toft,

I did what you advised last night. 

With Bluetooth off and everything else on, I rebooted my phone and did not turn bluetooth back on at all.

I went to bed with 85% battery and woke up 6hrs later with 82%. This was in the same room of the house that I was experiencing a 15% drop the night before.

So I have to agree that part or all of this standby drain is caused by a bluetooth bug when it is used in a single charge cycle. As Dan mentioned even if you turn it off during the charge cycle it still appears to cause wakelocks and drain the battery when idle. So by restarting the phone it starts fresh with no apparent wakelocks.

Hopefully enough users can submit some error logs where this is apparent as it could be something related to Bluetooth and the associated scanning it does much like Wifi.

Does anyone know anywhere official that this can be logged with so the Pixel and/or Android team can take a look at our findings? Or is logging via Bug Reports on your phone sufficient?

Cheers,

Pete.

Hi Peter Firth 8845,

Glad you were able to reproduce, from the logs you submit they can see which wakelocks were in place and for how long, unfortunately my replies in here keep getting flagged as off topic, but another way to demonstrate the issue is using AccuBattery and looking at the phones time in deep sleep (if there are wakelocks it will never go to deep sleep)

I also have submitted (and dumped to my pc) multiple bug reports.

However I can't replicate it in safe mode which means it's cause by some app, or setting.

I have been experiencing some battery drains as well since I first received it. I don't think it's just an overnight drain issue, but an idle issue because it seems to affect my regular day usage as well, but isn't noticeable because I'm on my phone during the day. 

After a full charge, phone typically says phone should last 17 hours - that seems wildly inaccurate for what people have been touting this battery as. I am getting roughly 6+ hours of SOT with the battery saver on (set at default 15%).

I decided to leave my phone off the charge and in 6 hours, the phone went down 13% which isn't as insane as the 40% OP has, but I left a 4XL off the charge last night to measure and it only went down 5% with Always Display on! My P5 I had to turn it off because watching the % tick down during idle drove me crazy!

Some say that the bluetooth is the reason, I just can't do without it since I have a fitbit watch and requires all day BT (never an issue in the past).

I am also having concerns with the overheating on this phone, and the inconsistent wireless charging speeds (also not an issue on the 4XL on the same chargers). Thinking that this phone maybe wasn't ready for primetime. Hope Google releases a fix as my return window is nearing.

Hi,

@Peter Firth8845: I have actually found that when the phone comes off charge, initially, the phone idle is quite good but it seems to get worse (this I have discovered is as @Tu Duong says happening during the day but you don't notice it as much as you are referring to the device regularly so thinking it's going down about right). For the first couple of hours after charge my device goes down less than 1.0% per hour but then sooner for no apparent reason accelerates to the 2.5-3.0% bracket again. This might be to do with the fact that I think the phone is very optimistic to say it's 100% charged as it still seems to charge for sometime after it has reached 100% when you look at Accubattery. 

I will be doing a factory reset to keep Google Support happy and then seeing how I get on and submit another bug report to them assuming as I fully expect to get the issue again.

@Dan Toft Interesting you can't reproduce in safe mode. I assume BT is on?

@Tu Duong. I had a Pixel 4 XL before and it's standby time was good with Fitbit and BT always on but got much better when I switched from Fitbit to Polar watch. This has only started since switching to Pixel 5. It's a shame as the phone itself is great. 

I do wonder how we will find out if this is some hardware issue for a certain batch of phones or a general software issue as surely there would be more people complaining about standby time if it was simply software...

i was experiencing terrible battery life, including constant battery drain when idle.
Since i changed preffered network type from 5G to 4G, it has completely and utterly sorted my battery problems.
No real drain any more when idle, and even when in constant use, the battery life is nothing short of fantastic.
I have a moderate 5G signal where i am, so disappointing to not be taking advantage of 5G speeds, but until there is a software fix, i'm leaving 4G as my preferred network type.

Hi Sam, that is not a solution for everyone as I don't have 5G where I am and so it automatically connects to 4G (I've even set 4g as preferred) and it's made no difference. Do you have a device connected 100% of the time through BT?

Hi all,

Just wanted to add my two cents to this thread. I had the same issue with the battery draining overnight (around 20% battery loss per night). So at 75% one night before sleeping, I decided to put it on safe mode and it went up to 77% initially which was weird, then only lost 2% charge overnight.

Since then, I've done a factory reset and last night I left the phone with Bluetooth off, WiFi off and lost around 5% charge which is a lot more reasonable. My battery graph is what I would expect to be too.

However, the battery life still isn't great and definitely isn't living up to the reviews online I've seen of people going 2+ days without charging their phone. I consider myself to be a light user and only use my phone for messaging and internet browsing. I'm definitely charging my phone everyday whereas my previous 3 year old Huawei device could last a good 2-3 days without needing topped up. I really hope Google get to the bottom line of this issue. I don't want to feel like I have to be careful with what features I have turned on/off and indeed have to disable features such a Bluetooth as I really need it for track and trace in this day and age..

Sorry I can't offer any more advice, a factory reset definitely helped me but I'm still not entirely convinced with all of these reviews online raving about the battery life of the pixel 5..

Hi Nick,

I'm starting to think that part of this issue could be related to an already reported issue regarding the battery percentage.

There is another thread in the Pixel forums related to the mis-reporting of the battery when charging. This has been responded officially to and is being addressed in a future update.

I've charged my phone in the last hour to '100%' but it started going down a lot quicker than it did yesterday. 

So I charged it again less than an hour later back to 100% but left it a little longer at 100%. Now I can see that the battery is draining at a normal rate for my use.

I'm not saying this is the smoking gun but I do think a part of this issue could just be related to a known issue regarding battery stats when charging.

Food for thought.

Pete.

I spoke with Google and seems like they want to replace the unit. Honestly, I may just return it. I'm getting this numbing sensation in my hand and arm from the unit when it heats up and not sure I could live with that.

Is the overheating a common issue for those in this thread? The phone gets hot doing regular tasks like browsing the internet.

====== HELP SOLVE THE ISSUE ======

Hello everyone,

For those of you whom like both me and Nick Austin 2216 that experience battery drain if Bluetooth has even been on in your power cycle I'm trying to find the source (Google doesn't seem to care since it doesn't happen in safe mode).

I got a strong suspicion that it's related to an app not supporting Android 11 properly - but testing 85 apps 1 by 1 would take me days, so I would like your help.

I want to find the apps that are installed on all the affected devices.

So if you would be very helpful to fill out this form (I'm not tracking anything, not even your email)

I used the app List My Apps to generate my list, but do whatever you're comfortable with, getting the package name would be a big help however.

Once I have a few replies I'll compare the lists and find those that appear multiple times, and post the results + test them on a factory reset phone.


====== EDIT  ======
I've got 3 replies so far (one is myself) - I appreciate your help!

Results so far:
11 apps shared by all 3.
13 apps shared by 2.                   
150 apps that are unique.

I'll be doing some testing tonight and over the weekend and report back.

Dan,

I am with you - it seems to be an app that is triggering this. I put it in safe mode, and it only drained about 3% overnight.

I immediately turned it back to regular mode, and it dropped down 3% which I am ok with if it netted 6% battery drain overnight. I had Bluetooth, Location, and NFC on so the culprit is definitely software based.

One thing I did notice is that when I rebooted the phone it went back to the pixel launcher. I was using Nova Launcher. And a few things I've noticed...

1. The idle is extremely better during the day. I turned ambient display on just to track the idle and it took 39 minutes to go down 1% all while the vibration motor is going on in an active group chat I have on in the background. 

2. Youtube and Youtube TV picture-in-picture resolved. I was losing this ability with Nova Launcher and the pip feature was just hidden in the background and would only show up on the keyboard.

3. Less heat when running certain apps. I am noticing that everyday tasks is not as taxing on the SoC and things like surfing the internet and playing videos don't make the device warm to the touch as it was the last few days. 

I am going to continue to monitor and hopefully this is the culprit, and will continue to use the pixel launcher. I like the pixel launcher, but I was just so used to the Nova Launcher that I was using it, so not a big deal.

So far nothing from removing the shared apps (the ones that are removable)

and just in case someone out there still claims it's 5G - looking at the logs from the phone it's clear that something happens the second you turn on Bluetooth.

Sooo good/Bad news.

I think I've found the source of the problem! - or well at least my phone is now going to deep sleep - I'll charge and report back in the morning with the actual results.

The bad news is that the app that seems to be causing the issue in my case was one that I'm the only one using (if it really is that app causing it I'll be reporting the issue on their Github) - I'll anyways since it clearly has some bug.

I'm currently factory resting my 2 xl again to see if I can reproduce the issue again w/ no other apps installed. - if I can I'll test with some of the other apps.

I've marked the apps that everyone but me shared with bold if some of you have some spare time and want to test yourself.


The way I tested was using adb (it's less hard then you think).
I run a logcat and monitor the screen when I turn on Bluetooth, in this case I was getting 1000s of "BtGatt.ScanManager: awakened up at time xxxxxxx" in a few minutes.


The problem is that even turning off Bluetooth didn't stop them, only rebooting. so it takes some time back and forth testing.


==== EDIT =====
Since everyone who submitted (but me) are from the UK I cannot obtain half the apps :/

Someone else needs to try and uninstall these and see if it makes a difference
BBC iPlayer
Google News

None of the others I've highlighted seems to cause issues (SEEMS), I would highly suspect the covid afaik it uses Bluetooth to track who you pass during your day.

Hi Dan,

I have uninstalled those and will see and report back. I had all of these apps on my Pixel 4 XL without this issue.

My factory reset made no difference at all in the end. I suspect doing as you say, stopping Bluetooth and then restarting will work but far from ideal.

Dan, first off thanks for doing the leg work. My peasant brain can't comprehend what you're doing, but I'm sure the community appreciates you trying to find the source of the problem. I have 130 apps on my phone, so I am not going to bother with adding any apps to your list.

For me, today started optimistically thinking that switching from Nova to stock Pixel Launcher would help the battery life on this and it may have been a placebo effect. I will say that my usage today was pretty intensive playing many videos, messing around with widgets, being in group chats that vibrated constantly throughout the day, and using exercise and music apps for an extensive amount of time. I managed to eek out 4.5 Hours of SOT with 14% battery. This was after me leaving the phone off the charge last night - so realistically; I got 4.5 hours on 93% battery (one can only assume unless the battery indicator was stuck). One thing to note is that I did have ambient display on today as I was trying to monitor the idle of the battery and at times the battery would sip super slowly, and at other times it would move a bit quicker.  I'm still not super impressed with the battery life because I had to plug it in at 5pm to fill it back up, so SOT is decent (I guess but idle time still not the greatest. I've attached some screenshots.

One thing is that the phone is considerably cooler throughout the day, and the tingling/numbing sensation I was getting from the phone has dissapated which is good.

My battery has been awesome, until today for some reason. 
This has me baffled. 
Btw, the reason for the dip and rise is being connected to Android Auto throughout the day. But the phone has been unplugged for about 6 hours as of this screen grab. 
How does 3 minutes of Google use up 22%?

Just wanted to report back, 7 hours idle results in 6,5 hours of deep sleep or a 3%, all while connected to my smart watch - so I suppose problem solved for me.

@Nick if you uninstall the apps and then reboot you should be able to use bluetooth as normal.

@Tu D. No worries - glad it's appreciated even though I'm spamming a bit :-)

Please go ahead and add your apps, it only takes a minute, and could help narrow it down even more, I'm letting excel to all the leg work on comparison.

I see that you have bluetooth on, does turning off bluetooth and rebooting help? I know it's annoying, but try to go a while day without ever turning on bluetooth (or if you do turn it on, make sure to reboot at soon as you switch it off).

Thanks Dan. I forgot to thank you for all your efforts. I'm glad you have sorted your issue. I

 am taking a slightly different tack. I have uninstalled those apps (though it's disappointing to have to take that course of action) and establishing that the phone is ok with BT off. I then plan to turn on BT once the phone has gone beyond a few %age points of discharge so I can see if it comes back and if it does the true extent.as I have said before, I believe the battery percentages are top-loaded. It takes about 90 minutes to charge to 100% but there is still charging of around 400mah after that take another 90 minutes before charging fully stops.

@Nick Austin 2216, No need to thank me, really what we should be doing is complaining that google makes it so hard to track what's using battery :)


Sounds like a reasonable plan, once you've assured that it solves the problem you can start to install the apps one by one, once you've identified the source you can post it here and reach out to the devs.

It appears to be related to the Android API level 30 changes to how Bluetooth scanning works.
In my case I'll live without the app until a fix is implemented, all it did for me what show me my AirPods battery life - not like I'm ever outside and use them anymore 😂


I would also HIGHLY recommend BetterBatteryStats if your phone isn't rooted you do need to connect to it via a PC and ADB, but it's fairly easy to do, and it allows you to see what's keeping your phone awake. - it really helped me to at least identify which wakelocks were in place.

Hi Dan,

Thanks for your input here. Ok. Unfortunately, those apps did not see any noticeable difference. So at the moment I'm faced with the choice of using my smartwatch properly or switching Bluetooth off and restarting the device. Even then the battery drain is better but can be quite variable still

Google support who I've been dealing with whilst posting on here, have taken me through various loops to go through, again no difference in the end result so they are sending me a replacement device. It will be set up exactly as this one as this set up is what the one I had on my Pixel 4 XL with no issues like this. It will be interesting to see if the new device has the same issue.

Same issue here, 

I haven't noticed it before last night. The battery has been ok up until now but not as great as some people are reporting.

My phone was at 100% when I went to sleep last night. When I picked up the phone this morning it was down to 63%. I checked battery usage and there were no apps that had been running. In fact it was only ambient display (2%), phone idle (2%) screen (1%) WiFi (1%). 

By my calculations that only amounts to 6% so where did the other 31% go?

I see people saying switch this and that off, remove certain apps but I've never had to do this with my previous phones and I certainly won't start doing this now.

We need a fix for this asap or I will be returning my P5

Yesterday was a lighter day of use, and so I thought I may get a better day of battery. Took the phone off the charge around 10am and went to bed around 1:00am.

These are the results after turning the Bluetooth radio off and then resetting. 

While it lasted me through the day, still not the impressive battery I am expecting. At this rate I'm getting about 5 hours of SOT which is simply unacceptable imo.

Dan, I attempted giving my phone access for batterystats, but couldn't find any adb devices. I downloaded the platform tools, ran command shell, and tried to run basic script to recognize the device but kept getting an error. I'll hit you up on discord for some help.

In the meantime I'm turning my BT radio off and only using it when necessary. We'll see if that does the trick.

@MrBelter Have you actually connected anything to the phone with Bluetooth in that time? Wondering why you stumbled upon this thread if your battery life is so good. Be happy!

Most of the time the battery drain causes because of the third party apps, device settings or else if you're using a third party charger. when the problem arose the things we can try is to re-install the recent downloaded apps and by testing the issue in safe mode and FDR.

Charged my phone before i went to bed and in the morning was 100%. Im not a heavy user the usual suspects, fb, emails, WhatsApp, music, phone calls and so on, i am on my second day today without a charge. Started the second day with 64% and im now on 43%, confident ill be ok till the evening.

Last night I turned off Now playing from lock screen and also turned off 5G (4G preferred) Went to sleep with 60% woke up with 51% so it was a great improvement.

Tonight I'm going to turn lockscreen now playing back on and leave 5G turned off and see what happens.

Hello everyone! Same issue here, on my brand new Pixel 5. I think I've noticed a consistent battery drain during night since the first day I got the phone, but this morning in particular I woke up with a clear 20% less than yesterday when I went to bed (everything on: bluetooth, WiFi, NFC, GPS).

Well, reporting my personal experience about some possible solutions that have been written here:
- I switched off 5G the first time I turned on the phone out of his box, so I don't think it's the problem we're looking for (btw, of course I'm happy for those who solved the issue in this way!)
- It seems the battery percentage stuck issue while charging is solved now (after the last update a couple of days ago, with the November security patch). I had that issue too, talked with Google (fun fact: I'm from Italy, and the Italian support team acted like they had never heard about that problem, while I was reading Google was fully aware of it in almost every single forum out there! They offered me to replace the device!) and waited for the update. So, I don't think the problems are related to each other
- I also did the procedure recommended by Dan. Generated a bug report, uploaded and analyzed, but nothing strange appeared! So, no app to uninstall for me I guess :(
- Now playing was already unabled too

SO...I just deactivated Pixel Ambient Services, Pixel Buds and Pixel Stand. I'll keep an eye on it and see what happens tonight, with everything turned on. If it doesn't work, I will try turning off something like bluetooth, WiFi or GPS.

Kirtis,

Do you have the Always on Display on as well? I am losing about 10% overnight but chalking it up to push notifications, gmail syncing, and AOD during that time.

I had a good discussion with Dan just to see if the phone was going into "Deep Sleep" - I imagine you had the same conversation.

For others, I would recommend installing AccuBattery and monitoring your battery usage. 

Stolen from Dan:
1. Charge your battery for about 5 minutes or so and it should reset your AccuBattery stats
2. Remove off the charger, all your stats should reset to 0%
3. Let idle for 20 minutes or so
4. In your Battery Usage (under Discharging) check your deep sleep %

When your phone is idle, it should be in deep sleep mode where you save the most battery. Mine was hovering around 70-80% which is normal. If you have a low percentage here, it means your phone is awake and consuming gobs of battery; there is an operation or app that is causing this to happen in the background. I would suggest following Dan's steps on how to track that down if you can't find it in the battery usage.

Hope this helps others.
