Yesterday a mix of people who own Google Pixel phones and other devices running Android 9 Pie noticed that the software’s Battery Saver feature had been switched on — seemingly all by itself. And oddly, this was happening when the phones were near a full charge, not when the battery was low. As reported by Android Police, initially it was assumed that this was some kind of minor bug in the latest version of Android, which was only released a few weeks ago. Some users thought they might’ve just enabled Battery Saver without realizing.
But it was actually Google at fault.
The company posted a message on Reddit last night acknowledging “an internal experiment to test battery saving features that was mistakenly rolled out to more users than intended.” So Google had remotely — and accidentally — changed a phone setting for a bunch of real-world customers. Several staffers at The Verge experienced the issue. “We have now rolled battery saver settings back to default. Please configure to your liking,” the Pixel team wrote on Reddit before apologizing for the error.
