When/how to charge the iPhone for optimal battery life?
Should you wait until the iPhone is really flat/ low battery and then charge it up full, or are smaller and more frequent 'shallow' charges healthier?
I also heard somewhere that every couple of months or so it is a good idea to let the battery run completely dead and then charge it up, in order to calibrate it or something... but that doing this too often could be detrimental.
Any help/ advice would be greatly appreciated! I don't know if I should let my iPhone run really low before charging it or if smaller more frequent chargers are the way to go.
Thanks!
