I have had my iPod Touch 4G since Christmas, and it has been plagued with bad battery problems ever since I first used it. Especially overnight, it will almost always lose 50-70% of its battery. I have read almost every thread about battery problems, and I have tried everything. I manually close every app after use, I don't play games, I don't use Facetime, I don't have Fetch on, screen brightness is only about 60%, etc. I took two screenshots from last night and this morning, where after unplugging from a full charge I left it on the table overnight (8h) with no apps open, and when I woke up it had lost at least 50% of its charge. I had the same problem with two iPhone 4's last year before I returned them - it can't be that I'm getting lemons every time. The only thing I leave on is Push and Wifi, which people tell me to turn off to improve the battery life. This is ridiculous. I bought the iPod to have instant access to my e-mails, not to turn all its functions off (which I almost already have). In any case, receiving ONE e-mail in the span of 8 hours cannot explain how it can lose 50% of its charge overnight. I don't know what else I can try, I am getting fed up with Apple portable devices.
