My phone’s battery percentage seems fairly steady through most of the day, then drops quickly once it gets near 20%. It doesn’t happen every time, and I’m not sure whether that points to an aging battery, a demanding app, or just an inaccurate reading.
Has anyone figured out how to distinguish a real battery problem from a percentage estimate that’s off? I’m also wondering whether cold weather or a recent software update can make the battery percentage estimate behave this way.
