More than half of the time I'm using my iPad Pro, I'm using it at my desk with a Bluetooth keyboard. It is no issue to plug it in while I'm using it, but I'm not sure if that is what's best for the health of the battery? If I use it while it's plugged in, it will stay at 100% the whole time. Does that mean that the time I'm using it does not count as a battery cycle? Is the iPad just using the power from the cable to run? Or is it continuously drawing power from the battery and then topping off the battery? If I were to use it for 5 hours without keeping it plugged in, I'd probably have about 50% battery left by the end of the 5 hours. I could then recharge the battery. That would count as a half of a battery cycle. I know after 500-1000 cycles, the battery life will start to degrade. If I were to use the iPad while plugged in, will that reduce my number of battery cycles?
