    In that thread a lot of people have very low counts despite having 1+ year old phones.

    I got my 4s on launch day and I already have 170 cycle count. Is that how many times my phone died? Because I find that hard to believe it went to 0% and back to 100% 170 times.

    Cycle count is how many times the battery has gone through 100% of its current capacity worth of energy. Example: Use 20%, recharge to 100%, use 50%, recharge to 100%, use 30%, recharge to 100%; all that counts as one cycle.

    As shown here, your battery does not have to die for it to go through a cycle, if you go down to 50% twice, that counts as 1 cycle.

    So if I go to 99% then to 100% 10 times, its 10 cycles?

    No. You'd be only 1/10th the way through a cycle count. If you did that 100 times, then it would be one cycle count.

    It pulls its data from iOS' IO tree. iOS pulls it from the battery's internal circuit. The internal circuit is fairly dead on following a recalibration and remains correct for about 50 cycles after that until it starts to loose some of its precision.

    It loses accuracy, not precision.
