Did you ever do that thing where you wake up in the morning and realize that your phone or your tablet hasnâ€™t been charging all night? Youâ€™re heading out for the day in half an hour, so you need to charge it up fast.
First of all, charge it from the wall. Charging from a computerâ€™s USB jack is much slower.
Second, donâ€™t use it while youâ€™re charging. Put it to sleep. Otherwise, itâ€™s like trying to fill up a bucket while waterâ€™s draining out the bottom.
