Battery drain after updating to Android 12 in pixel 4a
1
After updating to Android 12, the battery seems to be draining at a significantly higher rate on my pixel 4a. Losing a percent per 15 minutes when the phone isn't in use. This wasn't the case before the update. I used to get 24 hours of full usage in a single charge. After the update, I need to charge the phone twice in a day.
Please look into this and resolve the issue.

Thank you.

Thank you for the reply. I have tried all of that and still facing battery issues. This is after the Android 12 update. Before that, I had excellent battery backup.

I have noticed exactly the  same problem with my Pixel 4a after installing the Android 12 update. Pretty weird that the upgrade breaks something that was working well till now : The phone basics take more priority than any other bells and whistles.
