FS#136 - rather high battery discharge while Pandora is powered off
The Pandora does seem to use too much energy while it is turned off. A testcase: The pandora was turned off over night (about 8 hours) and battery state dropped from 98% to 96%. When removing the battery from the pandora for the same amount of time, the state is not changed at all.
This is based on the zaxxon firmware release with hotfix3, beta2.
Problem: if you don't use the pandora for a while and forget to remove the battery you can cause a deep discharge which might damage the battery. This is also a problem if the Pandora does eg shutdown itself since power is out and you can't directly attach it to a charger.
Possible causes:
* Design fault in the board.
* Too much powered on while the device *should* be completely powered off. The only things that should get power are the clock and the power button. This should basically not drain much.
Regarding the clock: The PalmPre is based on the OMAP3, too. There you basically have no discharge when it is powered off, so it is unlikely that the fault is in the OMAP3 itself.
