Battery drains to 50% then stays there.
After my old battery's liftime was over I bought a new one, put it into my HTC Wizard, then switched the device on.
Everything worked fine, the battery was 'preloaded' to 50% - I thought - because that's the value the battery indicator was showing.
After charging to 100% I plugged the Wizard off and I could almost watch the battery draining back to 50%.
BUT: Because the battery lifetime from 50-10% is that long (aprx. 2d standby and 4h gprs/bluetooth/display > ON), I don't think it's a battery hardware problem.
On the battery was written: 'Charge to 100% - then put into device' but because I don't have an external charger, so I didn't follow this suggestion.
Could it be a problem with some kind of calibration (maybe the device reminds the 100% voltage at some point?)
Sometimes this trick helps:
Switched-off device charging until LED light's green. Then plug off and boot. Then plug back into the cradle and charge it up to 100%.
But as I said - sometimes it works sometimes it doesn't.
Any ideas welcome to get rid of this bug
