I'm not trying to be funny. You are being cryptic and dribbling out info. Finally you stated the problem.

I'm not sure of the answer. The problem may be the battery, or may be the BlackBerry hardware.

You didn't answer the question above about whether the battery is a genuine BlackBerry battery (OEM) or an aftermarket battery (non-OEM). You need to test with an OEM battery that you know is good. If you can borrow one before buying, better, but you need to rule out the battery.

It could also be a fault with the battery meter of the device. I've heard of running the battery down until the radio turns off and then fully charging in order to reset the meter.

There may be other hardware possibilities. Don't know. But now that you have finally stated the problem, maybe others will have ideas other than what I've already mentioned.
