when is th Backup battery used and for what?
thanks
the magician (and many others older model) doesn't have persistent memory, it needs a battery to keep its contents. The backup battery will not start your phone, but it will keep your data safe for a few days (after your main battery goes dead), giving you enough time to charge your battery.
Super!
thanks for the info!
Cheers,

Have you tried how long the backup battery lasts? Because once my main battery exhausted, and after 30 minutes I put on the charger, and saw the backup battery is at 80 %... So I think the backup battery lasts for a half day, or is it depends on what background porgrams running, or what?

Jam and all other wm2003 device have two type of backup battary option....
1)Which is situated in jam motherboard...a 3v battery...
if u remove ur man battery then it will keep power on ram for 30-40 min at most....after that a hard reset...
2)jam keep a portion of main battery for backup reason...that is if even ur main battery reach 0%...then this backup portion of main battery will keep power to ram for nearly 72hours (3Days)...if ths portion also reach to 0% then the 1st option will work for 40 min..
i think this will clear any quary abt backup battery of wm2003 device..
PS:new wm5 devices doesnt have any backup batter nor the 1st one nor do the 2nd one...as this is a persistent memory based os...thats is one another reson thats why wm5 devices have better battery performance then of wm2003..
we know that backup battery is important in wm2003, but does it still useful when we're in wm06? since the memory still be saved in the main memory..
just a thought= is there any tweak or registry input which read both battery (main and backup) as one unity (a big battery) so after the main battery drains, device will automatically change to backup battery...

The backup battery does not hold enough power to drive the full PDa..it would not last long at all...it is only used to keep the memory data intact.
Works without the backup battery..
I ran my BA for a while without the backup battery. The only thing that happened was that the clock resetted itself on reboot...
Dear forum!
I have the problem, that it seems like my Backup battery is defective. If I remove the main battery a hard reset occurs. So I removed the Backup Battery for replacement. But following is strange: When I remove the backup battery and turn on the device the status bar of the battery shows 100%. Is this ok. Normally it should show that the battery is not available.
Any expierience with that?

First i want to thanx again to dev. for root.... THX
I have one observation, whene i started to root my phone battery was on 48%, when i finished step 1. and boot the phone it was at 0%? same thing after i switch it off and on (now its charging normaly - but 48% was lost) Is it normal and would my battery regain the 48% and if the phone has some internal sensor for battery is there any way to reset that counter (shold i try to discharge battery completly or what)?.
thx for the reply
jep, its normal to have this. that's way they say that you have to have 50% battery charge...
Same thing happened to mine but when i kept it without charge
The battery was increasing by. It self back to. It original which i had 75%
Sent from my X10a using XDA App
by using root explorer app or adb..you can try to delete /data/system/batterystats.bin and then restart your phone
the batterystats.bin file will rebuild by it self and sync the battery power after phone restart
hey i worried about the factory resets phone to do much more than 8times per week. i dont ever to do resets than lower battery 20℅... after last reset battery discharge 3 hours 10℅. before last reset not drain quickly just 2% per 8hours without battery saver. i did when the phone is turn off when 0 battery i put on charger and see 0 battery so i power device. is it bad ??? i want my old battery status.. or maybe i waiting for battery calculating time ? because not show how many hours left to discharge.
