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.

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..
