So, I have recently noticed that the battery in my iPod Touch is acting, strange. I have had my iPod touch 4 for a year now. The battery drains EXTREMELY quick and when I recharge it, it also recharges EXTREMELY quick. In less than half an hour, it is supposedly full. I am afraid that I may have charged and discharged my iPod too many times and the lithium battery is losing memory. But then there is the strange part. When my iPod starts to drain, I sometimes set it down because I'm kind of scared about it now. But when I come back, it "magically" increases in battery. For example, the battery icon was at about 3/4 capacity and went down to 1/2. When I checked back later, it went back to 3/4 capacity? I'm not sure if there is a bug in my ipod that is making this happen, and if so, how can I fix it? Are there any updates that can fix this?
I have not updated my iPod recently (maybe a few weeks to a month).
