A month or so ago, I noticed my Lumia 1520 couldn't keep charges or something. I'll have phone charged to 100%, but after 15-30 minutes I get low battery pop up and it shuts off. Sometimes, after plugging it in, I find it actually isn't low and can work with it more once I manually turn on battery saver (which won't turn on automatically anymore). Other times it is actually at 2% or whatever.
In the beginning, I dismissed it as buggy Insider Builds. But after updates weren't fixing it, despite reporting it once or twice in Windows Feedback, I backed up in the insider rings. That didn't help over time either. So I did a full reset, got out of insider builds and to the official AT&T build they sent out recently. Still didn't remedy it.
So.... Thoughts? Is it a battery going bad? Or Windows 10 being persnickety?
