Takes about 1 hour to go from 0% to 100% ,it gets really hot while charging...normal right? but when i leave it overnight in the morning or even at midnight when its done churning showing the green indicator, the mac and charger is VERY COOL, like normal when not charging. SO, is it dangerous to keep it charging overnight? I don't mean dangerous, but not good for the battery? I guess no? Because its detecting its fully charged and in a way seems to DISABLE charging , keeping the MAC cool and not letting it heat. Any thoughts? Should I leave it overnight? Charges full in 1 hour But i cannot wake up to turn to off I turn it off in 6 hours when I wake up. Not recommended/recommended?
