How to Fix Android 12 Battery Draining Issues

While the OS update to Android 12 has heralded many good features and surprises, a few problems have also sprang up simultaneously. One such issue is that of the poor Android 12 battery life. A device’s battery life is always expected to improve with updates and upgrades, so this unexpected issue has been making  rounds on many discussion boards.

In this article, we will go into detail about what could be causing this issue, and how we could find a workaround. We have laid out 7 simple ways in which this issue can be fixed. But first, let’s begin at the basics and see what could be the reason behind your Android 12 battery draining fast.

Why is Android 12 Battery Draining Fast?

There’s no telling why Android 12 battery life has been disappointing many users lately. Moreover, it is especially hard to figure out what could be causing the issue for your device particularly. So, it’s best to go with a few commonly observed causes and guesses. The general consensus points towards it being a server-side issue that will correct itself if all software updates are installed, and the device is factory reset. Here’s the catch: downloading the previous backup after factory reset has proven to be counter-productive, so it has been widely recommended by developers to let go of the backup, and start anew following the factory reset

While this can very well solve the issue, the reason behind your Android 12 battery drain could result from a slew of other malpractices as well. If your mobile data is set to always be active, even when you are using your wifi (for smooth transition between networks), or if you have turned on features costing more battery life, you could be facing the same issue. You could also be facing this issue if your Android 12 apps aren’t updated and have bugs in them or the apps aren’t optimized enough causing them to drain more battery.

The bottom line is, whatever the issue might be, the fixes remain more or less the same. Now that we have a vague idea of what could be causing the issue, it is time to take a look at the fixes.

  1. My battery would stay 3 days with android 11. But after 12 Now only 1 day and some hours. Which is a little annoying. But almost every solution on this list is either unacceptable or even worse than the battery lasting less than 2 days.
