This certainly seems like a stoopid question, but the more I try to figure this out the more I don't get it. I've read the posts on this forum, read Apple's battery info and I'm more confused for all this info. What I think I know: Apple recommends 1x a month running the iPad's battery down to 0, till it shuts off and then recharge back to 100%. This helps the battery maintain its full charging capacity for longer. Then the area that gets so grey: In the past with an electronic device like my phone or camera or laptop, whether I use em some, a lot, a little-during the day, once home I charge them up for the next day. Regardless of whether they need charging or not, I will "top them off" to start at 100% charged in the morning. But with an iPad should we keep running the battery down until it gets to 20%, 10%, 5% before recharging it. OR?! is it okay to plug it in in the evening b4 bed, even if its at 75%, or 63% and "top it off" for the next day? CM battery illiterate or perhaps over thinking things?
