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...
Hello,
I need your help with the following problem:
I have been using my Jasjar for 5 days now and I have a problem with the battery.
As soon as it gets to 35-40% battery power the unit switches off without any notice.
The only way I can turn it on again if I put it on a charger, and than it turns on again like after a soft reset.
I installed the latest ROM from the clubimate but none 3rd party applications.
Please let me know what can be this problem.
Thanks,
Zsolt
same problem here
Hi Ronaldovic,
Have you tried with another battery or just the original?
I was advised to change the original battery as that might be faulty but I couldn't get a new one yet.
Zsolt
For the O2 XDA Exec the battery has a 6 month warranty. You should check the situation with the JJ
battery issues..
I had similar issue and also where on switch on the screen light goes off and back on. This seems to be linked to battery chargin "top-ups" therefore sometimes the supply from the battery is not continously smooth. Try fully draining your battery and charging fully
I have same problem with my Exec. Any solution ??
I buy new battery but...when it gets to 25%, still switch off. So I dont think it's error of battery, may be it's bug of ROM for Exec???

1 month ago I have same problem. I think is not battery.
I make upgrade by all the ROM (JAS JAR, QTEQ, MDA PRO ecc.) but the problem I have not resolution, and 2 week ago my pda (MDA PRO T-Mobile) go in htc warranty.
Sorry for my bad english.
I have also noticed this problem a few days back. My Jasjar switches itself Off when the battery goes down to 22%.
I never used to have this problem when my Jasjar was with the original factory installed ROM version which was 1.13.53 WWE, Radio 1.03, ExtRom 1.13.137 WWE. When this ROM was installed I used to get the first low battery alarm at 20% and when the battery went down to 10% the screen would dim out and the SD card would deactivate, but still the unit would not shut itself out.
I installed the updated ROM when it became available in March which is 1.30.76, Radio 1.09.00 and ExtRom 1.30.164 WWE.
I am not too sure if the problem is linked with this ROM as I usually never allow my battery to run that low. However a few days back when I forgot to charge my battery I noticed this problem. I repeated this deliberately a number of times and each time the Jasjar shuts itself off exactly at 22%.
Just wondering if there are any solutions yet.
Regards
Same here, device just dies @ 26%. Was going to buy a new battery, but that might not resolve it?? *sigh*
RE
This battery issue has been discussed in two other similar threads.
In my case I just changed the default battery to a OEM one and everything works fine :lol:
Isn't the default battery an OEM battery? I'm tempted to buy one of the 1750 mAh batteries off of ebay (original JasJar battery is 1650 mAh) - is that a bad idea?
Try overnight charging of the battery for one or two days..this will solve yr problems... :lol:
Hi,
hard reset to your device, don't forget to get backup contacts, sms and data.
battery issue
I've had similar issues. Screen goes blank when battery low, plug in to charger and all is ok. What I've found is sometimes, not always, the battery screen brightness has gone to 0, but on-mains is set for full brightness. I never changed it, so maybe the device is trying to save power itself.
MNB.
Same here. My Jasjar dies sometimes when the battery is on 60%, 50%, 30%, 20%. etc. If I use the internet or camera or something then it will go dead, but not everytime.
Sometimes I can use anything and it will last till about 10% when the SD Card disables, then I charge it.
Don't know what to do. I don't want to buy a new battery if I'm not sure that is the problem.
Yes the same on my O2 Exec. Crashes at around 32% no matter what. Only remedy is to put it on charging again.
This started after I upgraded to the lastest O2 Rom; prior to that there was no problem whatsoever and I could go down to single digit battery percentages without any issue.
Is it the new ROM? Is there any work around to this malady?
Thanks to all who reply, in advance.
Cheers.
Well judging by the number of threads on the subject this problem is very widespread, check out the threads below:-
Jasjar shut down when battery power remaining is less then 43%

http://forum.xda-developers.com/viewtopic.php?t=54649
perhaps it is heat related?
XDA Exec keeps randomly soft-resetting
http://forum.xda-developers.com/viewtopic.php?t=54066
-----------------------------------------------
So can we say that downgrading does not fix it, or removing certain software combinations?
has anyone actually proved that replacing the battery works or not?
With the issue this widespread (and across carriers) has anyone tried to contact HTC about this? I still have my doubts that this is ROM related, seems more likely to me that many of the initial batch of batteries have gone bad.
My battery is on order with expansy. Expect it in the next 4 to 5 days and will definitely let you all know of my experience with the new battery
Regards
My device : Imate Jas Jar, see below.
My device was doing soft resets when my applications were going in and out of data contection by different software tools, data connection via Wifi or GPRS.
For example I would open Netfront 3.3, then close it and then device would soft reset. I would turn on wifi, then turn it off, the device would soft reset.
Well all I did was change the (orginial) battery over for a new one and all works fine.
All I cant work out is that the power spikes requires to do connection functions must have been to tough for the battery, hence the battery wearing it self out. I have no idea otherwise.
Any ideas...I dont !
i have the same issue now!
do you confirm that changing the battery solves the problem at 100%?
Thanks.
Bye
Yes.. a new battery did fix it.
Is this right, am I reading one of the first battery issues on a Universal running WM5 as opposed to the other battery issues under WM6?
other strange issue from me :0)
After changing to WM6 my Device( Universal) use to shut down ca. by 30-35% remaining battery reading. After following so many post here I thought my battery is going down.
However just recently for few days I have flash back the original ROM. Now comes the strange issue: After flashing the original ROM I have observed that I could use my device (with same battery) down to 5% reading.
After one week later flash back the WM6 and see there the device shutting down again by 30-35% battery reading.

I have always and still do suspected a falwed battery interface driver in WM6 but could not technically reproduce it. This is still a work in progress for me but its good to know that there might be a real problem after all in WM6.

Same problem with my qtek s200, WM 6.1 Korand WWE 3.1
I used to have the same problem...after getting a new battery, things seem to work fine....I think it's the battery's aging...after using and recharging for many cycles..after a few years...
S200 is 6 months old, and it starterd to do this afer installing WM 6.1..
donno where to set this turnoff level ?
Mine will also turn off @ 30%. But, it only does this when you use the WiFi.
I had problems with charging my M600. It would also turn of, even when being charged, but not at 30%. It would normally charge to 100% and then turn of and only show the red light....
Looking for sollution, I overlooked the fact that the SDCard was still in it. So I took the SDCard out and now my M600 is working again.
I also have the same problem on I-mate JaMn
Try changing or re calibrating the battery.
Taken from the Universal WiKi (should work on the Prophet)
Charge the battery overnight with the supplied poweradapter, not with the USB cable
Drain the battery without SD-card, powersaving off and backlight on full
At some level, the device will turn off. Switch it on and go to the bootloader and drain the battery until it's really empty
Charge the battery again with the supplied poweradapter
Hello all,
I got my HTC-8525 from AT&t about two years back. Then I moved to India, I got 8525 unocked from AT&T, where I have used the phone regularly. I have even flashed some new ROMs, Radios etc.
Now, I came back to USA. I tried to use a SIM from AT&T in the phone. But when I insert the SIM in the phone and activate the phone mode from connection manager phones battery starts discharging very quickly, at the rate of 4% per minute approx. When I try to use phone without SIM in flight mode battery works OK.
Even I have replaced the battery with a new one, flashed original AT&T rom with radio and even tried couple of Radios also.
Can someone guide me, what can I do now? Is it a hardware problem?
Thanks,
Alex
Try turning off HSDPA (under Settings -> Connections -> Advanced Network).
Thanks for reply, but I am not able to find out Advance Settings in connections under settings.
Is there anything else also that I can do?
Can anyone help me?

Alex
