Hi,
I have an Imate JAM, it does now show battery status. When I go to Settings -> Power, it shows 0% and with it, it says 'Unknown.'
What to do?
It does charge, but doesn't show charging status.
have you tried a hard reset ?
Yes, I have tried hard reset. It used to happen occasionally. The phone does charge. I know it because if I don't charge, it just shuts down to let me know that the battery is fully empty now. This error occasionally gets fixed. It does sometime start showing the battery status, but then again goes back to the problematic condition.
Try using other battery meters like "Ariel battery meter" see what they indicate.

do u live in a city where temperatures are near zero? this could be one reason.
or
backup ur data on storage card, flash rom 1.12.00 and see if anything happens.
or
if ur device still works perfectly with this problem, ur magician is having a hard time determining the amount of battery remaining...can still contuniue with it.

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.
Hello guys... I have a problem in my O2 mini. every time the battery indicator goes 50%, my O2 mini shuts down, and I need to recharge the battery again to at least greater than 50% to turn it on. Can somebody tell me whats wrong? could it be the battery ? I already performed hard reset but still the same phenomenon occurs over and over again.... Meaning I could only use my O2 mini as half the time as the usual xda mini... Kindly help me please...
I had the same problem. My device started shutting down below 70%, so I knew it had something to do with the battery.
I replaced the battery and now I can still make calls at 4%!!
Try installing a new battery and see if it works..
Good luck..
ITS A MIRACLE!!! no father... its Coat Saver
Its just so mysterious... I was charging my xda 2 mini thru pc usb.. suddenly there was a blackout of power ... then it turned on again... i checked my mini... its not charging but the thing is...... it can now be operated below 50% ... it doesnt shuts down below 50% anymore... WHAT A MIRACLE!!!!
Same problem with mine, below somewhere around 50% puff!! Maybe it's the hardware battery indicator that is stuck and returns values fairly optimistic about the drownage of the battery.. and maybe traumatise it like joysonx had done would make it right. Who knows!!
same to mine
me too, mine can't work below 60%.
Maybe I should try joysonx methode to shocked the battery.
Cross ur finger hopes it work.
The indicator always stop at certain %, but it show full charged after soft reset /////Does anyone has same issue?///
I have the same problem
I have no problem on my Jade. Try install ArielBattery (freeware from xda) .. this app shows detail battery % to 1% increment.
I've the same pb. After one night charging, the led doesn't turn red. But this is not critical.
Try not to suspend the 3G during charging, but only switch off the backlight
this problem was by me too in November,
make a hardreset. It has helped me.
I made hard reset before 2 months.Still i have this pb
ya me too....
notice its sometimes only. after off and on back its ok
same problem here.
Back to the store tomorrow
I've been having this strange problem these last few weeks. It happens in different ways.
1. Bellow 25% phone randomly shuts off then when i reboot its 0% battery.
2. Bellow 25% at random % I lose phone signal then the phone starts to lag and capacitive keys don't work then the phone shuts off and when i power it on its at 0%.
3. Phone gets to 15% i plug it in to charge, it doesn't charge but discharges to 0% then shuts off and after that it charges.
If i remove the battery then put it back in after it says 0% it may show 30%/20/15/13/25/30 etc. Sometime it doesn't charge after 87% or 92%. Is it the battery or is something else at fault? Also i can't get more then 2h15m screen time whatever i do and wifi drain is 30% in gsam.
Earlier I had same problemes on my Note 1 and it was because of my battery. Probably your problemes are becuse of your battery too.
Ok I will try a new battery.
I have exactly the same problem!!!!
Like exactly.
However I'd like to add some things:
1. Sometimes the radio signal for mobile starts randomly cutting in and out. It will be full bars, LTE, then nothing, no signal symbol. Then Full bars again, then no signal. In 1 minute revolutions. I am not physically moving during this time.
2. Even at near full battery the phone will get super laggy, stutter, and then finally crash. Once it reboots the battery will be 40% or something. Not super low but lower.
3. The camera seems to have a huge effect as well. I will open the camera, take a picture, and the picture won't save...it will just start to freeze the phone up until I have to pull the battery or it reboots on its own.
I also have a new battery coming in the mail.
However I should note that I am Note 4 910-H using a 910-C variant Custom ROM.
I was worried it was the special Modem I flashed to make the C variant ROM work on my H variant phone that was causing the problem.
Great, but unfortunate to see someone else having this issue too.
Ill post results of the new battery here.
Btw, ive been able to resurrect it from a very low state of charge (3% etc). The only way to do this is to use my fast charger. The fast charger is the only thing that will save it. Even then it takes ages to charge and gets white hot while it does. Its like the fast charger is battling for charge against some unknown force.
Post if you remember when you get your new battery. Hope that fixes it for you.
hi
my note 4 910c become very hot when i use the internet , can i change the modem from lower android like 4.2 to android 6 ? is it work ?
I have exactly the same problem and please if any1 finds any solution just share it here... I tried almost everything but not a new battery.
Battery Calibration By All The Ways, Battery Quick Start via *#0228#, Many Custom ROMs, Many Custom Kernels and Many Stock ROMs and the problem still the same even after I cleanly installed stock 6.0.1 ... Any help please.
Thanks in advance.
New Battery fixed 99% of my problems.
However the phone still randomly freezes and disconnects from cell service.
I think its the modem driver. Freezing might also be due to sd card.
