Hi All,
I rarely use my Magician device, and when i eventually turn it on, the backup betery is dead and often I need to re-install the whole things from scratch, as I have lost every single bit of information stored on memory.
I was wondering whether there is a tweak so that the backuo battery doesnt get used at all, instead the main battery, so this way I will not have the problem described above.
Thanks in advance.
The backup battery gets drained only after the main battery is depleated.
I got the same problem, phone turns off any moment and if i want tot turn the phone on he's resetting itself to factory default. Even when my main battery is 100%
possibly corroded backup battery.
Its the case with my I mate jam. I do have a XDA mini and it has no problems.
The backup battery is behind the loudspeaker, so dissassemble and clean, really.
And if your thinking if you can order a replacement batt, think again, i cant get a hold of a replacement battery so i have to clean off the corrosion every few months.
backup backup backup is the moral of the story.
Whitemoo.
Qtek s100 backup battery problem
Helloo,

I've just acquired an O2 branded (from HK) XDA IIs, and when phone powers up I am notified that the backup battery is at 0%.
Leaving the phone charging in its cradle for 2 days and backup battery still shows as 0%.
Have done both soft and hard reset, as well as upgrading to latest radio stack and OS.
Am I now forced to do surgery on this unit and replace the internal backup battery?
Has anyone performed this process on this unit before?
Hints, part numbers etc
I appreciate all help and thank you in advance.

In a seperate thread, Sandy suggested charging main battery first in aux charger location, and then trying to charge backup battery since she is under the impression that backup battery charges from main battery. (see Blue Angel forum)
Thanks for the suggestion Sandy.
However, the problem persists.
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.
What's the longest you've left it on charge.. I had a flat backup battery after it had been off for repair and it took over 3 hours on charge before it showed any charge being taken.
Also I did charge the main battery first as it does affect the ability of the backup battery to acccept a charge
Everynight for the past week it's been on charge for atleast 8hrs at a time. However this is not in a cradle but rather using 'travel' charger. Could there be a difference?
I remember hearing the same problem a while ago, and im sure the only solution was to get a replacement as it was a faulty device.
my o2 xda is running tnt wm6 for a long time now with no problems but recently my battery has started draining super fast like right infront of my eyes it drops percent numbers. i run battery status but that has never bugged the battery before. i also tried switching batteries with two of my friends and their phones run fine but mine drains fast. i have charged it with both the computer and the charger. it charges super slow and upon charging when i restart it the battery drops something like 20 percent or more instantly. could this be a virus? i factory resetted my phone and formatted my memory card but im still getting this issue. please any help would be much appreciated!

try other ROMs.
the fact of the matter is that ive been using this rom for so long without problems and this battery charger thingy just started a few days ago. could this be hardware problem?
Time for a new battery. Try nothing else until you have replaced it, with a new one, not one from another phone.
new battery really? u mean a battery from another phone doesnt do? and yes my battery dies very fast even my friends battery in my phone. cudnt this be a problem in my phone then? cause its his battery
Its definately a battery issue.
Check out this thread and I think you will relate: http://forum.xda-developers.com/showthread.php?t=353780
Then go to eBay and buy an new OEM replacement for like $10 shipped. I think I paid $8 for mine.
I personally think it is a bug.
On three separate occasions using various roms, my battery would drain from 100% to 0% in an hour. I would reset everything, recharge and it would run normal without problems.
I do not know what causes this but it does appear to be a software glitch, at least in my case.
try to hard reset your device and then test (after backup your data).
this can give you the clear reason (in case of the rom was running well with you).
good luck
try another radio!
i had the same issue, but it stop draining after i ordered the new battery
I suspect that it is not the battery or the unit.
its right said:

Actually I am suddenly having the same problem with a brand new battery on a brand new Wizard.
I just loaded the newest Mfrazz Rom which seems to be fantastic in its applications, speed etc. however immediately on loading the ROM, my battery does get hot in normal use and drains to 30% in a normal day. I have even loaded the IRDA disable cab to no particular effect.
Is there some specific procedure to which you are referring for hard resetting the Wizard? I assume you don't just take out the battery?
Dead battery
Lithium batteries can be killed rather easily. I know from rc helis. Most mobile phones use lithium-ion batteries. Helis use lithum-polymer batteries but they have pretty much the same charactoristics. li-poly is a little more volitile, they can and will explode if you charge or discharge too much or too quickly. If you over charge, you kill it. If you over drain, you kill it.
If you are in a place where you get little or no signal turn off the radio. It will discharge quickly if it's searching for a signal. Also if you are not using the bluetooth or wifi turn them off, same thing. That's why they provided the Comm Manager. Try not to let your charge get below 20%. Definately don't let it run completely out or stay that way long.
A dead lithium battery will not hold a charge at all. Just like you see, the numbers dropping off quickly. It will charge fast too.
(Snot the battery)

Looking at it afresh, it isn't the battery which is heating up on installation of this ROM, it is the unit itself. The battery seems to be remaining at a comparatively normal temperature though the heat generation does drain it very quickly as I said.
Not sure that this problem has ever been addressed before on these boards? It may be something to do with not flashing to a manufacturer's ROM before flashing to Mfrazz's new one?
Has anyone ever seen these symptoms before?
In addition to some of the other posts ,you could check this :
WM6 may need to "learn" the battery levels again.
Try FULLY discharging & recharging your battery 3-4 times.
If this doesn't make things better, maybe you should check if you are running anything strange in the background...

Lithium batteries don't recover like ni-cad. Spend the $10 and solve the problem. DONT EVER FULLY DISCHARGE A LITHIUM-ION BATTERY. That is the quickest way to kill it.

As far as I am aware it is difficult to FULLY discharge one of those batteries in the Wizard? The unit starts giving error messages when it gets to the 15% level and some time thereafter shuts most of its functions down to prevent this. Whenever I have had problems with these units getting hot and even discharging and shutting down, the battery level never seems to be at 0% when I plug it in again. I have never thereafter found any permanent damage to the battery.
I think we should address the problem which seems to be in issue here which is that somehting in the OS is causing the battery to discharge as opposed to replacing the battery and watching the problem continue. At least, that was MY problem.
I am obviously not saying batteries don't die. All I am saying is that for a lot of users, the problem may lie elsewhere. Meanwhile I have flashed back to T-Mobile and re-flashed the newest Mfrazz which SEEMS to be quite VoIP friendly and overnight the unit doesnt seem to have heated up.
since i cant order a battery from where i live i tried reflashing my phone and memory card and i think that fixed it. maybe in my case its an os bug. and yes i definitely have been treating my battery badly on discharging and over charging. thanks for the info
They are not that delicate if you know what kills em it's pretty easy to avoid. They don't develop a memory like the older ni-cads. if you are going to store one charge it first. They don't power drain by them selves unless they are in a device. Just don't leave a battery drained. Also they wont over charge in the phone. The phone will stop charging when the battery is full, and 0% is not actually 0volts. There are built in safeguards for the average user.
What will happen if I leave my Old Imate Jam without charging for many days? I am not using it. Will I loose everything? if the battery dicharges?
Nope. It'll eventually reach a point where it just shuts off because it's not receiving power.
Technically speaking, after your main battery drains, you phone may then switch to a backup coin type battery (I don't know if your phone has one), and after that drains, the worst that will happen is that the date and time on your phone will reset to factory. That's it.
Thanks jadel and kraize for your support.
Hi, when my phone (Galaxy S4) turns off due to low battery, I can actually turn it on again and it boots. However, when it finishee booting, it turns off istantaneously. I can do this a lot of time (over 100!) and the battery won't run out of juice. I think the battery might have some more juice to use for the turned-on phone, so my question is:
Can I recover this battery in order to correctly send information to the phone about its status?
It's an original samsung battery and I never replaced it, but maybe it isn't yet time to replace, since it seems it has a lot of juice left. Should I madly press the power button until it won't start up (and maybe reset the status indicator in some way)? or maybe there are some of the contacts on the battery to short circuit to do so?
Any suggestion will be appreciated thank you!
Hi, my sisters gave to me her old Galaxy S7 and I refurbished it: new cover, new display and new battery. Now I have a problem: when the phone reaches 40/30% of charge, it just shut down, no alert, nothing, the screen just goes black and if I try to restart it nothing happens, it's dead! When I attack the charger, it says the battery is at 0%!
I don't know what to think... the battery is new and this isn't the first time something like this happens: my previous phone (a Huawei P8 Lite) had the same exact problem; at 15% it just shutted down so I thought it could be the power outlet or the charger but I changed them both (now I even have an original Samsung charger!)... What could be the problem?
You didn't change the charging board when you were refurbishing the phone, right? You didn't change the whole motherboard as it seems.
Five things I can advise you to do:
Try battery calibration tips found everywhere.
Try simple factory reset.
Try installing the latest stock firmware, erasing everything in the procedure.
Head for custom ROMs.
Change some EFS components about the battery, it helped me somehow.
Did the previous owner had the same issue?
Thanks for reply btw no, I didn't change the motherboard since it worked just fine for my sister, the only problem was the previous battery that discharged pretty fast;
1. I calibrated the battery two times already, no fix :/
2. Did it already :/
3. Already did it
4. Guess I have to try
5. Is there a guide online to do it?
No, my sisters didn't have this problem, fast discharging battery aside, the phone didn't just shut down.
(sorry for my poor english)

On stock ROM, my device has a magnificent battery that I couldn't find in any other ROMs, although much of the ROMs has a great battery backup. So for you having such an issue, makes think maybe there is a problem about your new battery.
Try reverting back to the old battery, and check if it does the same loop.
EFS is probably the most important partition in your device, it is risky, and considered illegal to jiggle with in some countries, so, unless you are ready to take the heat, I advise you to not.
Phone reception plays a huge rule in the battery's backup duration, sometimes you can sleep with phone on 100% and wake up with ~60%. So maybe the carrier you are using has a really bad reception?
S7 tends to shutdown when phone's temperature is ~600°, and battery drains very very fast when phone is hot, maybe you have an issue with one of your motherboard components?
