1 I was wondering if there is a way to see how many charge cycles and battery capacity you have left on an iPhone? I have tried using iBackupBot, but it says I have used 15 cycles, but my iPhone is 2 1/2 weeks old, and I usually charge it up from 60%. So, is it possible that I have only used 15 cycles? 2 At what percentage should I charge my iPhone? Like I said, I usually use it untill 60%, but I was wondering if thats ok? I read that with Li ion batteries you should do shallow charges, is that true? My main concern is that I am on a 2 year contract and I am very conscious of keeping my battery healthy. Should I even worry about when to charge? Any advice on my questions and iPhone batteries in general would be appreciated! Thanks!!!
