Samsung’s One UI skin is pretty optimal and offers a lot of cool features and a sleek design. However, the South Korean company has added some aggressive background app killing policies, according to Don’tKillMyApp.
Don’tKillMyApp is a website that ranks Android OEMs based on how they handle background app management.
Typically, the website lists OEMs like Huawei, Xiaomi, Asus and Oppo as problematic, while Sony and Nokia do pretty well. However, now Samsung is in the first place as its aggressively killing background apps, thanks to One UI 3.0 and 3.1.
The South Korean company has implemented a new restriction that stops apps from staying awake in the foreground. This is on by default and is pretty different from what other Android devices do. Further, the shift has broken some health apps as they aren’t able to gather sensor data.
9to5Google, which first reported this issue, has found a workaround for the issue in the Settings menu: Settings > Apps > Your App > Battery > Battery optimization > All apps > App Name > Don’t optimize and then toggle off the battery optimization.
Previously, Google said that it would prevent other manufacturers from doing killing apps running in the background, but it seems that hasn’t stopped Samsung.
MobileSyrup staff reporter Jon Lamont noticed that his Fitbit wouldn’t sync properly while reviewing the Galaxy S21. One UI 3.0 aggressively shutting down apps was likely the cause.
