How many charge cycles does it usually take before the battery level indicator is actually accurate at estimating battery level? Also, when doing a battery cycle, do they mean fully letting the iPad battery die and then recharge it to full battery or just to use it normally and just recharge it a few times once I'm done using it? Off-topic: I'm loving the iPad keyboard... It's very very accurate and responsive and I can type on it at a rate almost that of how fast I can type on a physical keyboard... But I do make a mistake every one in a while.
