Should I let the battery fully drain then go for a full charge over night? Or does this not matter for the Ipads battery
I do that out of habit when I buy a new device, I'm sure sure it's strictly necessary though. I do think it's a good thing to do periodically (every few months). Probably doesn't have to be not he very first change, though.
Li batteries have "top memory", another wordsyou have to charge them to 100%. Ni batteries have "bottom" memory, so have to drain themе to 0. Ipad is on Li batteries and the only reson you need to drain it once in a while to calibrate your battery meter.
