Help Battery not charging correctly

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.
 
Thanks. My phone was already rooted so I tried the Battery Calibration app let my phone drain down to 97% and it charged straight to 100%. But I may have lost the beep sound because I was next to it waiting for it to charge but never heard it. I will let you know if I have further issues as this time I will let it discharge to about 40% before re-charging.

Hey Twinn, thanks for the continue support.

I did what you said when I heard the beep I pulled the plug out just to make sure it is at 97% (although it was showing 100%) then I plugged it back in I heard another beep it was only 10 mins after the first beep so assumed it was at 98% but I allowed to continue charging for another 30 mins and once I unplugged it, it was at 100% charge. So the battery is not a problem since it charges to 100%. There seems to be an issue with when the phone gets up to 97% in some way it gets confused thinking its 100% until you unplug it from the charger which then and only then it recognizes that it's still at 97%. Interesting scenario seems finding a needle in a hay stack to pin point why this is happening.

Somehow I have to calibrate the phone/battery so it knows it is at 100% while plugged into the charger and then beep.

Im going to try and wipe battery stats manually via ClockworkMod Recovery let the battery drain again and charge to 100%. Is the only option for now.

so u didnt do what i advised you... try once again what i said before. first charge to 100%, wipe battery stats, discharge to 0% and fully (without interrupting) charge to 100% but DON`T UNPLUG phone after beep! Leave it for another hour or so and then unlpug. it should be 100%. and then it should work normally next time when u hear beep, u can unplug and should have 100%. at least it worked for me and i dont have this problem anymore.
