okay there is a main battery and backup battery, once my phone was 20 perfect main, and like 30 perfect backup, when i turned the phone in standby the for a long time the main battery went to like 11 percent and the backup went to 100 percent, what do u need backup for, and what happens if it runs out?
The backup battery retains settings and data in the event of a dead main battery, so I assume if both went dead it would be similar to a hard reset, all would be lost.
the back up battery will be the one to hold every data in your phone once you run out of the main battery... it can only sustain up to 20 minutes and after that .. GODBYE to your datas.. unless you can charge your phone before this 20 mins grace period runs out.. goodluck
This morning when I turned on my imate jam, it immediately went into a hard reset. Once I had a chance, I checked the battery levels and the unit claimed my main battery was at 67%, and my backup battery was zero%
I have had my Jam 9 months and have never had this sequence of problems before. The screen was not left on overnight, and there were no applications left running.
Can someone help me understand how the backup battery could be drained and the main battery be OK? Has anyone else seen this behaviour?
It will take me several days now to 'rebuild' my Jam with all its apps and settings......
Had the same problem with my JAM. Happened about a month ago for the first time and then again today.
My battery indicator also showed 0% Backup and 67% Main Battery.
Downloading newest ROM update tonight. Will post again if problem persist.
I was using version 3 software, and have since upgraded to v11. What version of s/w were you using?

Oh man, that's the worst Coincedentally I've had a sudden HR myself only yesterday when I restarted my laptop with phone still connected via USB. Luckily I make a full backup every couple of days using Sprite backup. Works like a charm, not a thing lost, everything was put back as it was before the HR
I upgraded to version 1.12.00 WWE.
Everything went well until yesterday
Still the same problem
No response on using the on/off switch only a clicking sound sometimes. LED indicator flashing red.
Soft reset no effect
Had to hard reset.
After booting up - backup battery 0% and main battery 75%.
I phoned the distributers in South Africa and they think it might be a battery problem :wink: . I am loading my new battery for the required 8 hours tonight. Will post again in about a week to report on progress
I also use Sprite Backup and set it to do a backup every night. It works very well a restore my system without any problems
I have an MDA Compact, I am also on ROM Version: 1.12.00 WWE, and have the same problem.
There again, I had the same problem before I upgraded recently too, so I can't say for sure whether it is a ROM problem.
Like the other posts, I am very careful not to leave BT, incoming beams, backlight etc. on. I also shutdown any running programs I am not using.
Yesterday, I had to do a full restore (using the Backup.stg file over ActiveSync) which worked a treat. Still, I am very frustrated over this intermittant backup battery drain problem. Especially when the Main Battery is showing over 90% full.
This "feature" seems to be a common problem.
Any other thoughts?
One week with a new main battery and .....
So far so good. No need for any hard resets this week
Had a message of low backup battery once after installing SysWatch Trial but system power utility showed full backup battery. Hopefully this was only a software problem as i didn't get it again after uninstalling syswatch.
Just a quick update
My problem seem to be something of the past.
Look like the main battery might have been defective after all
I have similiar problem since 3 weeks ago
HI,
My Imate Jam has rom version R 1.12 D 1.13 WWE
and since a month ago it started showing 0% backup battery.
I called PPCTECHS because they upgraded my jam to 128RAM and they told me to force a hard reset.
I did it and it worked for a coupled of days but jumped from 0% to 100%.
Then anytime I do a SOFT reset it shows me the message BACKUP BATTERY VERY LOW and the led is always flashing while the pocket is off or on 24 hrs a day!!.
I will buy another main battery and try your recomendation.
I am very desperated.
The led on my Magician is always flashing as well when the pocket is off or on
24 hours a day, on battery use.
The "backup battery" is the internal battery of the device and as far as I know is not user replaceable. The purpose of the backup battery is to give you 35-40 minutes to change the main battery before you lose everything in RAM. Replacing your main battery will not resolve the backup battery issue.
PPC Techs give 6 months warranty on their workmanship so if the backup battery issue occurred after the upgrade..contact them again and see if they can do something about it.
Thanks
I already ordered a new battery, but will contact PPCTECHS anyway. Thanks
Just an update.
This problem is gone. Looks like it was the main battery. Maybe a problem charging the backup battery?
I think it's a common problem. I bought a O2 XDA mini in German last year. And when it was shipped to China. I flashed GER rom to CHS1.3 Rom. When I got it, this problem still happen. As I checked it, it's backup battery problem. So today my colleague brought it back to German. Because my O2 XDA mini still under warranty. Because there are two years warrranty for O2 XDA mini in German. I hope they can help me solve this disgusting problem.
I had a similar AND slightly different problem. My phone died to a hard reset and then turned off soon afterwards. Instead of a red flashing light, I had a CONSTANT red light, (I think this means hardware problem???)
I removed the battery and re-installed it, did the hard reset keys, everything and the unit would not turn on. I charged it for one day straight, still would not respond. I then charged it for another day. Still nothing, (except for the constant red light). I had plugged it into the USB cradle and the battery charger separately but nothing helped.
I then (2 days later) plugged it into the USB cable at work, and this is where it gets REALLY weird!
The unit turned on, but the LCD has flashing, (like a loose connection), alternating between difference brightness it seemed. Once the hard reset stuff was over, I check the battery and the backup was at 28% and the main battery was at 94%.
As I left the unit to charge, (with the screen still flickering like crazy) it screen got better and better, though it sometimes still flickers a little.
Now, (2 weeks later) the batteries seem fine, I haven't had a battery issue since but this is the STRANGEST part!!! I can not increase the brightness beyond the third tick. If I move the brightness beyond that, it doesn't get ANY brighter! So I'm basically stuck right now at 3 brightness level only!
I tried a friends battery, and it was exactly the same, (brightness level), so I don't think it’s the main battery. Anyone have ANY ideas???
Hello
I had this problem for quite a few months,i did what some of u did and i bought a new main battery, and the backup battery was back to life again from 0% to 100%.
But everytime that i take off the main battery all my data goes in the same way as before even when the meters say that is on 100%.
Can anyone tell me why?is that a hardware problem with the backup battery?
if it is how can i get this battery? i've being searching on the internet and i couldnt find any shop that sells just one unit of this battery (Varta V18hrt).
Hi!
Varta V18hrt: where have you read that Magician use this battery for backup? Do you know how to replace it?
Thanks!
i took the backup battery out,so i could see the battery that uses!!it's quite tricky to put it back again!!
Today my magician took a short fall from ontop of the computer (which is on the floor) onto the carpet - no big deal I thought, but now it gives me the No Backup Battery problem.
I'm backing up all my apps and junk now since it fortunately hasn't done a hard reset or anything.
This seems very common, are the backup batteries in these things considered flakey? Difficult replacement?
Will have a look once I've backed it up.
Hello
As far as i know with the problem that i had, the problem wasnt the backup battery,just some problem with the main battery for some reason didnt charge the backup and make look like that it wasnt any battery there!
hi..
i've also got this problem.. my backup battery show 'none'. i've charging this
unit till its full..but my backup battery never charged up.. maybe its the
main battery problem. unable to charge backup battery.
by reading this threads it seems man battery problem.i'm gonna try to buy new battery(main)...and try charge again..thanks for
ur info...
On my PDA2k, when I looked at the battery display, it showed me the main battery and the backup battery.
On my M5000, I only see the main battery...? Does it have a backup battery? Am I safe to get the SIM out without it all resetting?
I'm guessing it is, but would like to be sure
The Universal uses persistent memory. Your data is safe if the battery runs down. Just like a mobile phone, when you change the battery etc you don't lose your phone back! Its taken M$ and HTC years to get this basic tech to market!
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,
Klenovsky

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...
regards

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...
