Hey there! I've been noticing a weird behavior of my battery for one week or so. After charging to 100%, it drops normally (at least as it always has) until around 55-65%. Then, it starts dropping MUCH faster. I leave home in the morning (8 am) at 100% and when I get back (5pm) I usually still have that, around a 65%. I usually charge it then, for if I have to leave or whatever, but this last week I've noticed that if I don't, after hitting 55% it starts dropping super fast. I've found myself going to have a drink with a 35% left and after just 2h without even touching the phone, picking it up to see the time and see a 2% left. This had never happened to me. Tried doing a recalibration, no great chance. It might've improved a little bit but nothing worth noticing). I've thought it might be the batter itself, but the "first half" of it seems to be working fine. I'd expect the whole time to drain fast and not from 65%. Btw, iPhone 5 with the following Cydia tweaks and apps: Activator Auxo BlurriedNCBackground Dashboard X FolderEnhancer FolderIcons Forecast Gridlock iCleaner iFile IntelliScreenX 6 NCSettings NoNewsIsGoodNews OpenNotifier Springtomize 2 SwipeSelection Winterboard (no weird themes applied, just icons changes and a bit of that). Thanks!
