New updates are added at the bottom of this story …….

Original story (published October 29, 2021) follows:

The stable version of Android 12 arrived with the Google Pixel 6 phones. Since then, it has also been available for other Pixel phones. However, some models have issues after updating.

Some Google Pixel phones experience battery discharge after Android 12 update

Some Pixel phone users report their battery life discomfort on their devices (1, 2, 3, 4). They point out that the battery life after the Android 12 update deteriorated significantly compared to Android 11.

After updating to Android 12, it looks like the battery is draining significantly higher on my pixel 4a. Loses one percent per half hour when the phone is not in use. This was not the case before the update. I would get 24 hours of full use on a single charge.


The reported issue appears to be present in much newer models. For example, many of the affected users have a Google Pixel 4a 5G or a Google Pixel 5, both released last year. So the problem is not limited to older models.

The problem was present in Android 12 betas

In Android 12 public beta versions, an alleged excessive battery consumption was already reported (1, 2). Now that the stable version is available, some Pixel phones still have the problem.

The problem is with the Android system intelligence service. There were many steps about this issue in Android 12 beta application. Looks like the issue has not been resolved by Google.
This was my first pixel phone, and if this is how Google tests its devices, this will be my last …


There is a solution

It appears that there is a solution that is supposed to help solve the problem, according to a report. However, not all affected users are willing to use the process as it requires a factory reset and clean installation.

1. Back up everything
2. Go to Settings / system / reset options / Delete all data (factory reset)
3. When your phone restarts, DO NOT RECOVER from backup
4. Once you have the phone up and running and the Play Store has updated everything, reinstall your apps from Manage apps & device / installed (drop-down menu). Switch to “Not installed” and select the apps you want.

It is not known if Google is known

It is not known at this time whether Google is aware of this issue. Among the reports, some product experts recommended that affected users submit their feedback. However, they do not confirm that the problem has escalated.


So at the moment, affected users can only wait for an official statement from Google on the matter. They can also try the solution described above.
