Google has announced that it is shipping an unexpected update to Pixel 4A phones this week. According to Ars Technica, the company emailed Pixel 4A owners to tell them the update will address battery performance stability but that their batteries may not last as long after it’s applied.
Google repeats that in a new help page titled “Pixel 4a Battery Performance Program,” where it writes that it had noticed issues with “some” Pixel 4A phones.
