Here is the gist of the article as a video:
New updates are added at the bottom of this story …….
The original story (published October 29, 2021) follows:
The stable version of Android 12 has arrived with the Google Pixel 6 phones. Since then, it is also available for other Pixel phones. However, some models are having issues after updating.
Some Google Pixel phones experience battery drain after updating to Android 12
Some Pixel phone users report discomfort with the battery life of their devices (1, 2, 3, 4). They point out that after the update to Android 12, the battery life deteriorated significantly compared to Android 11.
After updating to Android 12, the battery seems to drain at a significantly higher rate on my Pixel 4a. Lose one percent every 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 problem appears to be present in very recent models. For example, many affected users own a Google Pixel 4a 5G or a Google Pixel 5, both of which were released last year. So the problem is not limited to older models.
The problem was present in the betas of Android 12
In public beta versions of Android 12, alleged excessive battery consumption had previously been reported (1, 2). Now that the stable version is released, some Pixel phones still have the issue.
The problem comes from the intelligence service of the Android system. There has been a lot of talk about this issue in the Android 12 beta program. It appears that the issue is not being resolved by Google.
It was my first pixel phone and if this is how Google tests its devices, it will be my last …
There is a workaround
It appears that there is a workaround that allegedly helps resolve the issue, according to a report. However, not all affected users may be willing to go through the process as it requires a factory reset and a clean install.
1. Save everything
2. Go to Settings / system / reset options / Erase all data (factory reset)
3. When your phone restarts, DO NOT RESTORE from backup
4. When the phone is operational and Play Store has updated everything, reinstall your apps from Manage apps and device / installed (drop down menu). Go to “Not Installed” and select the applications you want.
We don’t know if Google is aware
Currently, it is not known if Google is aware of the problem. Among the reports, some product experts recommended affected users to send in their comments. However, they do not confirm that the problem has been made worse.
So, for now, affected users can only wait for an official statement from Google on this matter. They can also try the workaround described above.
When there is more news about the alleged battery drain issue in some Google Pixel phones after updating to Android 12, we will update this article with the relevant information.

Update 3 (November 03)
10:30 am (IST): While Google is working on a fix for battery drain issues on Android 12, we suggest heading to Battery settings> Battery Manager and then enabling the ‘Manage apps automatically’ option. , if it is not enabled by default.
With this option enabled, apps that you don’t use often will stop consuming your battery in the background. However, this also means that notifications may be interrupted in certain situations.
