Galaxy S21 battery issues appear after February security update

Samsung Galaxy S21 battery problem

Android developers have already released the February security patch. Most OEMs have started rolling out the update to their phones as well. The Samsung Galaxy S21 series is one of those few advanced phones in the game when it comes to receiving updates. A recent phone update added support for wireless DeX on PC. The February security update has already been received, but unfortunately, it is causing battery life issues. A thread on Reddit is open and now full of complaints from Galaxy S21 phone owners.


Interestingly, only those who own the Exynos variant are experiencing the problem. It is not known how many units have been affected, but it appears to be widespread. Some owners also reported that the battery drains faster as expected. Problems with cellular connectivity have also been shared.

It seems that the battery issue is temporarily resolved with the phone in airplane mode. It is not clear if all variants of the Galaxy S21 have this problem. We know that some Galaxy S21 and Galaxy S21 + are experiencing the mentioned issues. We are not sure if the Galaxy S21 Ultra has the same problem.

It can be assumed that the March 2021 security patch will follow and bring the necessary fix for battery life. If you own a Galaxy S21 and haven’t applied the February 2021 security patch, we suggest that you skip this one and wait for the next build.

Samsung is said to be aware of the issues. Now we are working on a solution according to our source. A new firmware update may be released soon to fix the problem.
