Perhaps the thread at http://lists.openmoko.org/nabble.html#nabble-td840534|a840534 would prove informative to you? If your battery is fully charged/almost full before you head for bed, then it is possible that it reaches a fully-charged state and begins to discharge soon after... which means that it has ?8? hours (dunno how long you sleep :) ) to discharge; while I have read estimates of battery life being around 8 hours, it may be less if you have WiFi, GPS, BT *and* GSM switched on... even if you have a superb GSM signal in your bedroom, possibly WiFi and GPS could have bad reception, causing even more power usage. I'm no software guru at all, but the import of bug reports and mails on this list seem to indicate (correct me if I'm wrong, please, people!) that the logic of whether to switch the charging circuit on is determined: a) on boot b) on detecting plug-in of a power source to the USB connector A third case should probably be added - if battery voltage (or charge percentage) drops below a specified number, check if the USB power source is still connected; if so, flip it on again, and let the battery charge. This, of course, is assuming I have the problem description correct :-) Cheers, Ed. _______________________________________________ support mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/support
