I just purchased a new 5s on Saturday and the past couple times that I've tried to let it charge to 100% fully it never says done charging. It will get to 100 but still have the lighting bolt not the completed symbol. I'm not sure if this is normal of what but all of my other iPhones would not do this. I've left it on the charging overnight and it won't completely charge. If anyone knows anything I would greatly appreciate it. Thanks!
