I am having major battery problems with my 7a. For the last month or so, my phone randomly just super drains to a dead battery, normally from around 30-40% to 0% in seconds. I literally watch the percentage go down or it just goes dead in my pocket. It's incredibly frustrating. I have all the battery optimisation stuff turned on. I don't play any games, I dont watch HD videos, or anything like that. It seems like it's more of a battery indicator problem than a battery problem itself. I saw some strange sounding fixes on another thread, which didn't work for me. I am considering a factory reset, but wanted to ask here first. On a side note, where I live is 30 degrees every day, so the phone does get hot, naturally. Any help is appreciated. Thanks!
