My phone has a number of battery related issues. Sometimes it gets hot, for no apparent reason. I check to see what's running, but there is nothing unusual. My phone will not show that it is charging if I charge it while it's on. I must turn it off to charge. But last night it did not charge at all, and showed the battery was down to 29%. Then, after about half an hour trying to figure out how to do a hard reset (still don't know), it shows 100% charge on the battery. Is my phone lying to me? Waiting to ambush me in the middle of the day. Is my phone just a lemon?
