Batteries and Samsung don’t go well together, especially after the company’s disastrous Galaxy Note 7. Malfunctioning batteries on the phablet caused it to be declared as a public safety hazard. Additionally, Samsung’s Galaxy S9 and Galaxy S9+ also develop battery drain problems after software updates. Now, it looks as if the problem might not be isolated to the S9 lineup. Take a look below for more details.

After Samsung launched the Galaxy S9 and Galaxy S9+ last year, the Exynos variants of the smartphones started to develop battery problems. Now, it looks like their successors might be in for a similar fate. Users on the XDA Developers forum are consistently reporting that their S10 smartphones powered by Samsung’s in-house Exynos 9820 are failing to enter deep sleep, resulting in a battery drain.
