I have a 1520.3 running the 10 preview. The phone is about a year and a half old. I haven't had any major issues until the last couple weeks. It started when I was playing games on the way home from work (public transportation), the phone would randomly pop up with the "Battery Critically Low" message and then shut off instantly. i could have a 90% charge and it would still happen. A lot of the time I would be able to turn it right back on and still have a good amount of battery left. I assumed it was game related.
A couple weeks have gone by and it's now started happening more frequently and seems to be completely at random. I did a hard reset a few days ago and it doesn't seem to have changed anything. This morning I had a full charge, used it for a bit, then was playing music in my car. I had checked a few minutes before and the battery was at 88%. Suddenly the "battery critically low" thing happened and the phone shut off. I turned it back on and it's now at 75% and working fine.
There have been other times this has happened in a similar situation and when I turn it back on the battery will be extremely low (like 3-10%), then I can reset it and it will suddenly say 50%. I can't make any sense of any of it. Any ideas?
