Today i was charging my phone from almost dead (like 10% remaining) and i plugged it into the wall charger. I went to make a phone call on while on charger and after the phone call i let it sit. At that point it was about 95-96% charged but i ran to the other room quickly and come back to find my phone it rebooting. That is the first time i seen it happen but im not always there while the phone is charging other times so this could of happened before. Is this a problem? What do you guys suggest? Thanks
