Google accidentally turned on battery saver mode for many users on Android 9 Pie. The Google Pixel community of Reddit on Thursday got flooded with user complaints on saying that the battery saver in their device randomly turned on for them, even if their devices were fully charged, reported XDA-Developers.
Many users noted that their smartphones with Android 9 Pie randomly saw this battery saver issue turned on in phone’s Settings. The battery saver was set to turn on automatically at 99 percent, which is unusual because Android only allows battery saver trigger threshold as high as 75 percent.
Google acknowledged and apologized for the issue later same day by noting that it was an internal experiment which mistakenly got rolled out to more users than it intended.
A Google representative noted on the Google Pixel community, “Hi all, some of you may have noticed that battery saver turned on automatically today. This was an internal experiment to test battery saving features that was mistakenly rolled out to more users than intended. We have now rolled battery saver settings back to default. Please configure to your liking. Sorry for the confusion.”
The XDA report also says that not just Google devices but devices other than Google also got affected by this issue. It noted that Nokia 7.1 Plus and OnePlus 6 running Android Pie was affected. Even more, a LineageOS developer building Android Pie for the Xiaomi Mi 6 was also affected.
