My nephew's iPod touch 4G is having some serious battery issue, a full charge takes about 2 hours but it takes only an hour of usage for the battery to drop from 100% to 20%. My nephew wanted to know if this is hardware/battery related or if a restore will fix it? If we chose to restore what's the proper procedure? We don't need to backup as my nephew doesn't have anything much on his iPod. If even after a restore the battery doesn't improve then we shall assume it's the battery. iPod touch 4th Gen on iOS 6.1.3.
