The Samsung Galaxy S21 series now receives a new update (G99xBXXU1AUB6), and it is added along with the February 2021 security level.
The change log is not quite as descriptive, and just like the update that came before it, there is talk of improvements in overall performance, security and camera. Although Samsung does not say this explicitly, it appears that the update is trying to address issues with power consumption caused by some users on a recent update. XDA Forums says it solved the problems.
The issue has also been acknowledged by Samsung and it is said working on a solution.
According to reports on Reddit and Samsung’s Community forums, the previous firmware update significantly affected battery life. This was apparently just an issue for the Galaxy S21 and S21 Plus powered by Exynos. Users reported that the problem was put on airplane mode, meaning it had something to do with cellular connection.
The Snapdragon models and the Galaxy S21 Ultra-powered Galaxy S21 Ultra are apparently not affected.
The new update is currently being introduced to users in the UK, Switzerland, Belgium and Germany, and is likely to reach more markets in the coming days. You can also check it manually by going to Software Update in Settings and tapping Download and Install.
