Evidently the calibration is off. Let the phone run until the phone tells you to plug in the charger. Turn the phone off, plug in the charger and let it charge overnight. Turn the phone oon and you should see a 100% charge level. If not, repeat once more. If that doesn't fix it, whether paying to get it fixed depends on 1) whether it bothers you (it should) and 2, what the phone is worth. It may cost more to fix it than to replace it.working battery, Shows 0%
