backup battery status still says 0% - MDA II, XDA II, 2060 General

I've even tried putting the phone on the cradle without the main battery to see if this would force a backup battery charge. The charging light stays red, and after a couple of hours, backup battery status still says 0% (so it's not a sensor issue), and if you remove main battery, it continues to be the same as a hardware reset.
On a positive note, xbackup seems to restore things quite well.
Can anyone else think of any good ideals?
The error message on boot-up emphasizes the problem
"To prevent possible data loss, replace or recharge your battery according to the owner's manual"
I find no such instructions in my owner's manual.
i have also purchased a new battery but still don know how to charge backup battrey

Could be the backup battery is dead my friend. You can google for the service manual to take the XDA apart. The battery is basically a large watch battery so a replacement should be quite cheap.
I had to replace the touch screen on mine, I wont lie taking the XDA apart is a bit of a pain. You will need a very very small screw driver and a torque (6 i think) screw driver.
Hope this helps

I had the impression that backup batteries stop'd working period when one went from ppc2003

Device is dead when starting up in the morning.

Good day,
I own a Orange M1000 now for 4 months, (Qtek 2020)
3 weeks ago I installned the Sin Merged v2.0 rom.
No problems, everything went ok and smooth.
Yesterday when I got home I have put my phone on my desk.
When I tried to start it this morning, nothing, it won't go on.
I browsed through the forums and tried a lot.
With no result .
(Hard reset won't work, can't get into bootloader, leaving SIM and battery out for a hour, charging the device with the adaptor).
The only thing I get from the device is a red light when I put in charger without the battery in the device.
I really don't know what to do now, any help would be appreciated!
*frustrated at the moment*
I don't want to be annoying, but isn't there any one who could help me?
I really need my phone for my work and school and I have no replacement at the moment.
Really, any help at all would be very, very appreciated!
I have the same problem today, all I can do is sending back to repair
Sorry, I may be stupid but it wasnt clear to me if you charged the battery in the cradle, ie battery on charge without phone.
Take the battery out, leave the phone on the desk and pop the battery only in charger. Wait 2 hours or so (minimum), now put battery in XDA and soft reset.
That worked on mine when it went mental like this.
thanks for your reply .
I just try and seem you are right.
the backup battery all gone and I charge the o2 without battery for an hour and the backup battery for 50% charged.
Is that the only way to charge the backup battery ?
It seems the backup batter takes its charge from the main battery. So if you have a totally flat backup battery (a non removeable one inside XDA) and put a fully charged main battery in, with no charger connected you will see the backup battery slowly charge itself from empty to full from the main battery.
This seems to prevent charging when the main battery is totally dead.
The only way to get it running again is to remove the main battery and charge it outside the XDA.
This is at least what happens on my XDA, so forgive me if its different for anyone else.
Thank you for your replies,
So it worked for you allen?
My problem is, I didn't get a cradle with my phone, and I can't get ik spare here at stores.
Sending back for reparation isn't an option.
I didn;'t have a lot of moeny and I bought it second hand. (still in box though..)
Any suggestions on where to buy a cradle?

Only 0% or 100% batt but nothiung in beetwin

Everything was just fine until yesterday when i realized the batterty's built-in monitor wasn't reading a real batt stat. I was sure I was running out of charge and the divice was still saying there was 50% left. I did a soft reset and my atom didn't boot. I took the battery off and waited more than 3 hours, put it back and couldn't boot. I haven't ever done anything to my mobile. No register tweacks, fisical hits or rom upgrades. I searched the web and found a procedure to get it back. Reset+camera choose 1 option and there you go with your device booting at last. I did so but when it ended whith the system loading proces it sent a notification saying that the battery was exhausted and it went off. Again it couldn't boot in a normal way even with the ac adaptor plugged in. I made sure the battery was fully charged. I did a bootloader again (reseat+camera) with the usb connected and i could get it back again but showing 0% battery indicator and would turn off as soon as i unpluged it. I tested the battery with a multimeter and even when it was fully charged i tried to recharge it until green light then i turned it on and the batt monitor was 100%. I could unpluged the usb and everything was fine. It didn't turn off but the indicator got stock in 100%. After an hour or so of normal use i was sure the battery was 90% or less while it was still indicating 100% of charge. I did a soft reset and couldn't boot again. I think the device knows when the battery is 100% charged but when it is less tha 100% and i do a soft or cold reseat the mobile thinks the battery is 0% and won't boot.
Yes, I have ugraded to ROM Xda-Atom-Exec-ENG-20060721-MOT0822 to see if this fixes it but now i have a rom-upgraded aton exec with the same fatal error.
I am at work rigth now and hopping my atom doesn't need a soft reset because if so i need to plug it in in order to be able to do a reseat+camera and wait some minutes until green ligth shows up. My atom knows 0% or 100% of battery charge but no numbers in beetwin.
Any ideas?
did you charge the battery for 8 hours on first use, continuing to discharge battery completely first three charges?
This is crucial for battery performance I now get at least three days of moderate usage and at least 7 days in standby, my advice is go buy a new battery follow the instruction manual completely, failing any changes (be sure to buy battery from somewhere you can get refunded) return the battery. Try also reflashing using bootloader mode, not using the SD card!
The last time i used bootloader was after hard reset a no card inside then i performed the last ROM upgrede available from O2. It seems to be a hardware problem more than a software problem as i thought at the begining.
I hope you are rigth, i guess the device gets charge information from the battery and the battery is telling it when it is 100% and 0% when it is under 100% and after a soft or cold reset. I am going to drain the battery all the way down and recharge it up to green light to see what happens. By the way i did not charge the battery 8 hrs when new.
Where do you think my atom is geting the batt charge information? From one of its inside sensors or from batt circuits?
Thaks for your advice.
I mean reflash using bootloader mode, ie. enter bootloader then plug in USB and run DSUU installer from your PC. Its hard to say where the fault lies, some Atom's had power management issues and O2 are fully aware of it, if yours is still under warranty I suggest sending it to a service center but be prepared to be without it for at least a month! (should change their name to SLOW2) and also be prepared to have it returned to you only to find they havent done a damn thing!
Its a bad battery, same thing happened to me. Just return it for a new one, the material is moulded with the smart chip inside there is no way to fix it.
Now my battery is beetwin 100% and 85%. I have searched other forums and i found out it is definitly a battery issue. It has been more than 6 months since i bougth my Atom so i have no more battery garanty. I thing i am going to wait before i buy a new one in orther to get the most of it since it still last more than 2 days.
Thanks for the information.
when a battery xp-02 (for atom family) is sometime stop at certain percentage, says 72% for long time, i do a soft reset and it drops to says 40%, is it a symptom of bad battery? or it is a ROM problem?

backup battery level has been disappeared!

Hi to all, and thank to moderators to keep this usefull site alive.
My jasjar was working good but nowadays it suddenly goes off and wont return untill the recharger connect. when plugging the recharger the red led turns on for about 30 seconds and then the phone comes on with yellow led turned on, and when I check the battery levels usually shows the main battery 100% has been charged and the backup battery level has been disappeared!
and after completing the charge process the led turns off instead of turning to green.
I have flashed it with the latest arabic rom and cleaned all necessary parts of mainboard with electronic contact cleaner. I have also measured the backup battery power on the board and it shows about 2.5 v that I think its ok. any idea is welcomed.
How old is your device?
Almost everyone experiences similar symptoms after 5-6 months, and then the battery dies. I haven't had the backup battery disappearing though...
If it still has the warranty(which I doubt after flashing a ROM...), you should have the provider change the batteries. If the warranty is still void, they can still order a new battery, but it will cost you a bit.
Good luck!

I appriciate your attention. Unfortunatly the warranty period has been expired, and I have tested 2 other jasjar original batteries (from friends) but still the problem exist.
I appreciate the appreciation.
if that's the case, you might want to take it to a repair shop, because this might mean a problem with the battery control or power routing circuits, and I don't think anyone should meddle with those, except maybe the designers...maybe the guys in the shop can do something, like a new motherboard , battery, or something.
Good luck in getting it up and running again!

automaticaly Hard reseted after take of battery

I want to know the reason and the solution.Plz. I need to change my battery frequencely.Right after I put a new one,and start my alpine.The align screen is showed again.All data settins are lost.It's just like after flashing the ROM.
I've searched this forum.But no results was found.I admt Maybe I need to study English harder.But plz do some help.

have you checked that your backup battery, the one built into the phone is fully charged before you take out the battery. (check in your settings menu under power)
i have replaced mine from a totaly broken xda (picked it up on ebay) as mine had failed and would no longer hold a charge for more than a few seconds.
i also had major probs with a hi powered battery it kept failing for some reason, totaly losing charge in a mater of hours on standby and this kept hard resetting my phone. so i no longer use the larger batteries.
The backup battery is fully charged
After have taking off the main battery about five minutes and putting on a fully charged one the back up battery might shows the power percentages about 25%.But It almost takes me about 30 seconds to change a another new battery,it's not possible the backup power's problem. I change battery exactly the same way when I do it.That's just too weird it sometimes hard reset and sometimes just doesn't.

The backup battery is fully charged even after having take off the main battery for three minutes!so there is nothing to do with the backup power.
I change battery exactly the same way everytime.Why just sometimes it gets hard restted and sometimes it doesn't.It makes me wonder.
Is this eda ii a broken one?Maybe I should turn it back to the repaireman's house for a few weeks?you know how bad China's services are ,they never do things that customers need.
Thanks your heartkinded help anyway

Thanks the same way though your idea seems not where the problem at.
like i mentioned it could just be because one of your batteries has an intermitant fail, as i said i had the same problem with a hi capacity battery, it somtime hard reset my phone for no reason.
just try buying a couple of new batteries, or lable your batteries and see if its only on one of them that the HR occurs.

Edge 7 freezing, no power, overheat

Hello people,
I have problem with my Samsung Edge 7 and please if you can just tell me what can be a problem and on which way should I go to solve this problem I would appreciate it very much. No need for step by step solution just tell me what can I do except send it to Samsung repair shop or recycle it. I will take it apart by myself if needed but I don't have a clue which part should I look to replace or what.
So... the problem is that I manage to charge the device one day when it don't want to charge and after that I managed to turn it on. Everything was working fine, didn't try anything much just unlock screen and put it to sleep.
After that I turned it off so it don't consume battery while I would be able to backup my data. When I was able to do backup I turned it on and it powered up normal so I proceed to backup my contacts (export to SD card).
When the export finishes phone just froze and I have to turn it off with POWER + VOLUME DOWN button combo.
After that few times when I try to power it on it just froze on boot up logo and I turned it off that few times with the same button combination as before. Until it don't want to power on anymore. So I tried to put it on charger to see if anything will happen, and nothing did.
I just left it to sit on my desk and I noticed that the phone is heating but I got no reaction at all from the phone (powering on or charging)
The day after when the battery was drained obviously I managed to charge it up again but when I power it on after it got to 100% charge it froze again and there goes same procedure as before (button combination restart, no response, heating, battery dead, charging...)
So now I can't even charge it anymore and I took out SD card to check if my contacts are there at least. But nothing, that contacts vcf file is not even saved on SD card even I choose that option when exporting my contacts.
Now I don't know what else to do since my phone wont even charge or power on and I would like to backup my data at least and then I can recycle it if I must.
So please if you have a clue just tell me where can I look at what can I try to do.
Thank you in advance and have a nice day
some of sgs has these problem. The motherboard is broke, i had same problem and sent to samsung service, they changed motherboard. I guess it's related to cpu temp sensor, inside the cpu.
Thank you Ganjax for your reply. That was the thing I was afraid of. So all my data goes away with motherboard?
I will wait few more days with some replies even I find your very useful and accurate since you had the same problem.
hey I also have the same issue, putting the phone in the freezer and letting it freeze makes it so that it can turn on for only 5minutes or till when it drops back to room temperature hopefully this will be enough to get your photos back.
millkyway4 thank you for you reply.
I am not in a possibility to try your method because I disassemble my phone and striped down battery for research purposes.
Neither I think that those 5 minutes will be enough to transfer all my data but if I ever reassemble my phone I will give it a shot.
So... Considering my research and striping down the battery the things goes like this (if someone is interested in this topic):
I disassemble the phone and remove the battery. Battery is connected on motherboard by some connector that I don't know the name or type, so if someone knows I would like to know too.
Since I couldn't find positive and negative lead on that connector (because of microscopic leads) little bit down on flat cable, near the battery, I removed coating and manage to find leads and measure voltage of the battery to confirm positive and negative lead.
By the measurements I assume that battery voltage is fine (~3.7V), but when I connect it to external charger which have built in ampere meter the battery doesn't charge as other batteries and ampere meter readings vary by 100mA +/- I set up to be initial charge. In normal case when I charge batteries amperes only goes down by the time the battery charges so I find this event an anomaly.
Since that is the case I removed the chip (from which the flat cable is coming out) that is on the battery assuming that it is causing that anomaly. Leaving the battery with only positive and negative lead that I connected and also measure and put on my external charger. But the same thing happens as with chip, or what is called, on the battery.
Going further with my research I cut down flat cable from battery chip (electronics) and connect positive and negative lead, I found before, directly on my charger on which I adjust voltage on ~3.75 volts and connect the connector with flat cable back to motherboard. So you probably see what I did here but if you don't the research I want to conduct is that my external charger acts as battery for the phone and I try to power it on like that.
In this case ampere meter shows 0 since the current which is flowing trough the phone is none. After I am sure that this is the case I tried to power on my phone with connected external charger like that and my ampere meter shown a current draw of 100-200mA on the POWER button pressed but the phone doesn't turn on.
So now I need someone with a little bit better knowledge of the phone, batteries, working order and type of connections like this to tell me what did I do right and wrong so I can prove that Ganjax statement, and my assumption, that motherboard is dead is really correct.
Ganjax don't mean I don't believe you or something, I appreciate your reply, this is just for research purposes because I would like to play with this stuff and that is the things that interest me.
And if there is some "fanatic" like that to tell me what can I do next and try or point out what should I do and don't make next please leave a comment and we can discuss this matter together and find out something about this case.
Thank you all and have a nice day
