Original story follows:

The Samsung Galaxy S21 FE has been highly praised by fans and critics for its stunning display, stylish and comfortable design, and good camera quality.

However, like any other device, the Galaxy S21 FE is also prone to bugs and issues. If you are experiencing an excessive battery drain issue on your device, then you are not alone.


Samsung Galaxy S21 FE abnormal battery drain

According to reports (1,2,3,4,5,6,7,8,9,10), multiple Samsung Galaxy S21 FE owners are experiencing an abnormal battery drain issue preventing them from using their phones for longer periods.

They claim to be getting about two to three hours of SOT (screen on time) even with the energy saver mode turned on, which is quite lower than expected.

Some allege that their phone battery drops by 1% even on turning the screen lock on and off.


While for others the battery drains quickly even when the phone is kept in idle mode. And undeniably, it is quite an annoyance for one to charge their phones multiple times throughout the day.

This is certainly frustrating for those who need to make use of the phone for their day-to-day routine or official work. Interestingly, a user says that the issue popped up after installing the March update.

I have Exynos variant of S21 FE and I am using it since last 7 months now. Totally disappointed with battery performance and the heating issue. I am getting an SOT of not more than 3 Hrs on an average.

Battery draining fast even with battery saver.

Customers have tried tinkering with various system settings and restarting their smartphones time and again but to no avail.

Potential workaround

Removing bloatware could be a potential workaround to put an end to the quick battery drain.

A Redditor claims to have removed Personalization service, group sharing, continuity service, visit-in, Samsung Free, and many other apps and got rid of the problem.

It is also recommended that you disable the ‘adaptive battery’ and ‘sleep apps’ settings on your device.
