Notes about expected battery life
Battery life is a work in progress. The power saving software is in a very rudimentary state. At the moment 12h is about the most (note though a recent result of at least 21h, mostly in suspend, with multiple short wakeups, on the predecessor device GTA01). A week standby and 6 hours talk, 20 hours mp3 might be attainable when power saving software is complete.
Make sure that the battery never discharges completely. This is an issue because the internal charging circuitry can not be turned on until the FreeRunner has booted, and booting through USB power alone does not work.
Should the battery become completely discharged, your options are: - Use external stand-alone charger (compatible with the Nokia BL-5C battery) - Boot the FreeRunner with an alternative battery, or with a spare GTA01 or GTA02 battery, plug USB power, then switch to the empty battery. - Boot the FreeRunner with a 4.5VDC external power source (steady hand and great care involved), plug USB power, then insert the empty battery.
Compatible Replacement Batteries
Other known good batteries (that can power the freerunner) include the bl4, bl4c. These may not work to revive a device and may not report charge information. It is probably a good idea to check that your battery is not greater than the stock battery's voltage of 3.7V unless you know what you are doing.
