The solution by ""Alyssa d"" works on iphone 4 and possibly other iphones. When you want to recharge (preferably on low battery, like 5%) connect the power cord and start the flashlight. Since the phone does not charge when it's on, the flashlight will drain all battery. That will make the phone turn off... so it will start charging! Even when it has enough power, it will not turn on! So it will keep charging to 100%! The only drawback is that you cannot use the phone during charging.
