I am not exactly a heavy user of my Mini 4 and wasn't considering the new one. That is, until I noticed a sharp drain in my battery over the past month or so. It doesn't last a day. I don't do anything different than when I first got it - play Words With Friends (45 minutes a days approx), read books, check email. However, the battery seemed to last more than three times as long when it was new. I did fiddle with the settings so as not to use the battery needlessly, but no help. I brought it to the Apple store thinking I'd get a replacement iPad for $99. But that deal is only good if the battery fails the Apple diagnostics. My battery came in at 98%. I don't know how that's possible considering I haven't changed the way I use it in 4 years. Any ideas? Now I'm considering the new iPad Mini. I don't really need the upgrades considering how I use it, but after selling the Mini 4, the cost would only be about $150, not much more than if I had the 4 replaced. I need to make a decision now since I will be traveling abroad for at least a year where Apple anything is considerably more expensive than the here (US).
