If your phone is having problems syncing with your Google Account, you could see a message, 'Sync is currently experiencing problems. It will be back shortly', or a Sync issue icon 
Most sync issues are temporary. Usually, your account will sync again after a few minutes. But if you keep having sync issues, try the following solutions.
Important: Some of these steps work only on Android 9 and up. Learn how to check your Android version.
The Pixel battery continuously learns your behaviours and optimises itself based on your most recent app usage. When you set up a new device or after a factory reset, optimisation may take up to a few weeks to take full effect. For best results keep Adaptive Battery and Battery Optimisation on.
It's normal for your Pixel battery to drain a little more than usual after a software update. This is because the phone is working hard to download and optimise the new software and get everything up and running.
If you still experience unusual battery drain after a few days, please let us know and we'll be happy to help.
