It is the original OEM charger that came with the phone. The battery I am having this issue with is the extended Mugen 3600mah one. If I plug it back in after unplugging it and let it charge for another 15 minutes and then unplug it it will read 100%. I do not have this issue when I use the Original battery. That would seem to indicate that the extended battery is the issue, but is it possible that the phone was "programmed" to accurately read only the OEM 1500mah one that comes with the phone?

Littlerichie, I also have a Motorola Mini USB charger as well as the USB connector that can also charge the phone. Ought I try charging the battery via one of those and see if this issue comes up?
