So one day a couple weeks ago I suddenly had a problem where I would find my phone powered off in my pocket at least once or twice a day. I thought it was my case wearing out and making it easy to hit the button. So I changed cases and got one that makes it kinda hard to hit them. This wasn't the issue. Then I noticed as I was using it out would shutdown as if I had told it to or the battery was low. I also saw that the battery percent gauge was fluctuating as much as 15-20%. Had anyone come across this? I searched around and couldn't find this particular issue.
