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...
I am having problems with the internal battery in my wizard. Everytime I switch battery my clock and calender resets. I have the service manual and see where the back-up battery is. I was just wondering what kind of battery it is and if I can just replace it?

The Wizard does not have a backup battery like other PDA's. It has a persistant memory model like a PC. I have never had to remove the battery so I guess the clock would reset.
Whether the Wizard has a battery or not there is definitely a design flaw. It always used to remember the time and date settings when removing the main battery buy after about 6 months it no longer does. this has happen on both our Wizards and many others. It's very annoying when you change sims and then have to reset the time and date.
So far nobody has been able to explain why this is happening. There are thoughts that it may be the new roms which have changed something in the power management.
Kiru, you say you have the service manual and have found / identified the backup battery? That would very interesting if there is one.
I remove my battery to move my sim to other phones quite regularly, and my clock/date settings always remain intact on my mini-s. If I look at battery stats on my SPB pocket plus, it shows 2 batterys. Main batt and backup batt. I always assumed the device had a backup battery to store date/time settings.....

He's talking about the small backup battery inside the device. If your sure Wizard has a backup battey, then yes its removable.
The type of battery, and volt is labeled on either side of the battery.
Just my $.02...
If this problem is less than a year old try warranty repair options?
Also, you can set the phone to update its time and date from the cell tower. I've never set the clock on my device it just nabs that information from the cell tower. Should happen as soon as you get a signal instantly...
The setting for it is under Phone -> Time Zones
Hope those help...
As i'm sure the backup battery is only used for the RTC (Real Time Clock) since the device is now persistent storage...

Just follow what FESCSteve said...and it should work....if not....then send me a pm and I can email it out to you
When i switched my mainboard my back up battery was dead, but after a couple days its back to normal, so i guess just keep charging your device and the back up battery will work again.
as for replacing it, it's soldered on so you'll have to unsolder it to replace it.
At page 37 of the service manual you can see about a "Golden Cap". It is not a battery, it is an high capacity capacitor. It works like a battery but has never to be replaced because it (should be) is charged by internal circuitry from main battery.
Aikon
okay I managed to get my internal battery working once again!!!.....I think is drained due to the fact that I don't charge my batteries with my phone, but use a desktop charger. I then plugged my phone into the charger for about 24 hours, and finally, the back battery is charging (as to what pocket breeze says) It still isn't 100% charged, but it seems to be holding the time and date again!!!... just fyi I have 3 batteries for my wizard and never charge them using the phone....so that could have been my problem.
same problem here

Last week my battery was totally empty so I had to charge it using my 220V charger.. At that time I also found out that my internal battery is empty when I exchange SIM cards. Last Sunday I charged my SPV M3000 for like15-20 hours but I still have the same problem...
What more can I do to make it work again?
I have same problem with my O2 Mini S. I charged it with the wall charger for around 18 hours although it took just 2 hours to get the the main battery fully charged. The date/time still reset when I plugged it out and removed the main battery.
Anybody kindly help please. Thanks so much in advance.
too bad my problem came back again....and I don't know why.....when I left my phone charging almost all day, my battery meter says my backup battery is 75% full.....then when i changed my battery.....all my clocks reset again...it's gets really annyoing especially if you change batteries alot. But does this only happen when people are using spare batteries?..and always swapping back and fourth?, I rarely use the phone to charge my battery as i have a desktop charger.

It seems that there really is a backup battery (capacitor) that can be damaged. I have read the Wizard service manual and this little component has to be replaced if this problem still occurs :-(....
both mine and my wife's wizards are only charged by the mains charger and they both loose the time and date settings when changing sims. This problem started about 6 months after having the phones so I think some component seems to fail after a while as there are many reports of this happening.
All I can say is that it's very annoying as I travel frequently and change sims often.
As for getting the time from the cell tower, this doesn't work for me for some reason.

Unfortunatly I have the same problem. When changing the sim and thus removing the battery I lose the time and date setting. I charge my phone by the mains charger or sometimes by an USB port.
Perhaps it has to do with the new ROM I use? I recently upgraded to the molski rom. Perfect ROM by the way.

I don't think it's the ROMs. I still use the original WWE I-Mate rom (2.16, the one and only update they did so far). It's possible that the ROM introduced the problem but then everyone using the ROM would have the problem which is not the case I believe.
My JAM starts to show me the message that says "Backup Battery is very low" and asks me to replace it. This message appears in random basis.
Well, if I look at Battery Status Screen (or even at Resco Today Plugin) the backup batt shows me 100% charged then goes to 0% (at same time of that message). In 4-5 sec the battery stats returns to 100%!!!!
And thats occurs even my JAMis plugged in charger !!!
About 2 days ago I install new ROM, at the same version than older, except that older is PTB (in portuguese) and the new is WWE. But both is same version.
I've search the foruns and find that backup batt is an Varta V18hrt. And it's impossible to fint it here in Brazil!!!!! And I don't see any place selling this battery in any place over the net. I really don't whant to buy this cell in any foreinger (outside Brazil) place, as I don't have any International credit card and I don't like things like paypal......
Then I have 2 questions:
Someone knows if exists any NiMH 1,2V thais is equivalent to Varta V18hrt ??
Case not: is somewere any chance that I replace the Varta by any Lithium (or even Alkaline) 1.5V cell ??? Doesn't matter if I have to replace that cell in a regular basis....
Thanks for your help.
dont think u need to replace ur backup battery. try taking out ur main battery n clean the points. it mite help.
I think maybe a soft problem... I've upgrate my JAM with 1.13 ROM+1.13 Radio+BigStorage and the problem stills occours, but less than before....
In 72h after change, I only see this problem 3 or 4 times.... Before it happens 30-40 times a day!!!!!!
Someone have experiencing something like that ?
There is no backup battery of Varta inside the Magician. It was a mistake by a poster who was referring to another device.
Magician has only a condensator, holding the data in RAM for a couple of minutes. The condensator shows up as "Backup Battery".
I have a similar problem of the backup battery not showing up at all, and a message "Low backup battery" after soft reset.
I ignore it. However the condensator still seems to work, because if I remove the main battery for a minute, the data is not lost.
There is definitely a Varta battery in the magician, I have just opened mine up and removed it
Its inside a steel can soldered to the main pcb, you need to pry the top off the can to get to the battery.
The battery is a Varta V18HRT button cell, and has 124 written on the plastic casing around it.
Cheers.

Backup battery is a small cell inside the phone that saves the time and date settings from being reset when you remove the main battery.
Hello guys i havae some problem with my Blackstone i use it from 2.5 years and i never had problem like this so..
Now when i recharging my device always stay on same % for example even for 1 hour its show always 20% or 50% or anything depends when i put it on the charger..
After restart can show 100% full or anything.. so i found out that the indicator absolutly do not work so if i restart it and show me the real % for example 50% the device always will show 50% battery untill the battery is fully discharged..
And right now i dont know how much Batterry i have and when will need to recharge..
I don`t know but i think this is a battery problem? i use this battery from the begining i mean from more than 2.5 years and maybe is time to change it?! but this heppand when i drop my device once on the floor so do thee is posible by droping the device some senzor to be broken or this is not posible i mean its a battery problem and i will need to buy new one?! or give me some idea how to test this and fix it.
Now no matter that the indicator do not work i still can use my device 1-2 days with one charge even if always show 20% this mean that in the battery itself have power for 2 days conversation internet and etc.. but just do not shown right.
Do anyone of you had the same problem ? and how do you fix it?
Also im looking to buy battery from ebay and i found today this :
http://cgi.ebay.co.uk/HTC-TOUCH-HD-...ultDomain_3&hash=item4aa9446824#ht_3230wt_905
What you think about this battery ? or can someone who already bought battery from ebay point me to get some good one
I read in the Diamond forum that peoples expirience the same problem with the indicator and even after Hard Reset or flashing new ROM the problem is still there.. so if this is right then i dont have reason to Flash again my device if the problem will be still here.
Any Suggestions?
Thanks
I did some tests... so i fully discharge the battery and i saw that even when the battery was on 0% and always the Warning appear i was able to play with the the Device with Wi Fi ON and Games and Music around 45 minutes wow.. this mean that the battery somehow was not calibratet and when its shows 0% in her still have around 30 40 % so after fully discharge the battery till the device Turn OFF by itself then few times turn it ON till there is not enought power even the WinMo to Startup i put it while OFF on the Charger and i was able to recharg to 100% and the light become green this mean the senzor itself work maybe just the battery need calibration again.
Now will see do the indicator work corectly after few more recharges and will write here for peoples who have the same problems in the future
...
hi dude, i think you should simply buy a new battery, but preferably an official htc battery - rather than the unofficial gold one you have posted a link to on ebay.
if you do decide to buy a new battery then put the new battery into your blackstone and charge while device is turned off.
this should fix your problem

Actually i think its not Battery die problem because i did some test and i see improvment my battery last at least 2-3 days with alot of usage wifi and etc so this is more than normal.. the problem was that the indicator do not work corectly and like i wrote above i discharge fully the battery till the device die and i saw that when my battery was on 0% i still play alot alot my device to swtich off this mean that befor when the indicator shows 0% its remain anorhter 30 40% power this heppand due to 2.5 years usage and i recharge the device when i have time not always when is fully without power and i think that this cause somehow a discalibration of the Li Ion so today when i did the trick i see improvments and now the indicator start to count ever single % so i think when i do this one or two more times the Battery will be calibratet and will show very corect how much Power i still have.
I think this way because if this battery was already died the device will not last 2-3 days with super usage.
