Ever since a couple of days ago my battery is not charging correctly. I have a very simple battery app that shows me the percentage of the battery charge. The issue is that when I plug the phone to charge from the wall socket using the original charger, the phone will make a beep sound indicating that it has charged while it is still plugged in, the battery app and the default icon that appears when the battery is charged it shows 100%. When I unplug the charger from the phone the app shows 96% this is also supported by the phones default battery icon as the very tip (connector) is not filled in green. This cancels out that the app is showing incorrectly. When I plug it back in to charge it will charge again to 97% make the beep sound and the same scenario is displayed. Unplug charger plug it back in 98%....until I reach 100%. I have done nothing different or installed anything from when it was working till this problem. The only conclusion I come to is I got a battery issue I need to replace. But I thought I would post the issue in case someone might have a solution. Thanks.
