JASJAR turns off at 40% battery!! Please help

When I got the jasjar 3 days ago there didnt seem to be any issues, so I upgraded to the Helmi_UNI_AKU3.3_v1.2 everything seemed to work as it should then my battery reached 40% and bam the device shutoff. So I tried the 3.5 and same thing, now I have my original ROM JASJAR_WWE_13076_164_10900_wwe_ship.exe back on and its a little better it gets to 33% then dies.
I know this wasnt happening prior to me owning this device as it was my close friend who gave it to me.
Can anyone shed any light on why this would be happening?
Thanks in advance.

You have to buy a new battery. Your battery is damaged. A few months ago I had the same problem. The Universal battery has a life spam of 6 to 12 months. At a certain point when you drop your phone or flash a new image, the battery forgets its state. It will think that there is enough power left but in fact the voltage is dropping to fast and the phone shuts itself off. Believe me you need another battery.

Thank you
Thank you very much for your advice, I just ordered a new one.
So when I flash new roms I should use my old battery?
Thanks again

Question
Does anyone know why batteries die so fast.
I had a battery the first go out at 20% then it grew to 55%
I couldn't use my Universal for a day.
I went back to the store and got a new battery.
I think, when you flash your device with a new rom and or radio. You should have your device fully charged.
Can anyone confirm?

Not sure on the answer, but I have 2 batteries, one 12 months old the other 2 months old & the Uni with 3.3 on it started this behaviour yesterday whichever battery it is using - roughly 30% left.
I am upgrading my other Uni to 3.5 just now to see whether that one suffers the same.
As I have a new battery & am having the same fault I am not so sure .....

It is a hardare issue, unlikely a software issue.

I do not agree. At first I had the same idea. I thought the device must be broken. I bought a new battery but still I had the same problem. But at the tech center thay gave me a free new battery to prove I was wrong. I got a original MDA PRO battery and when I use that battery it stops working at 2-3%.
1. So order an orginal battery. Use the old one when flashing.
2. Be sure that the battery is fully changed. Flashing can skrew-up the memory state of the battery. When that happens the current sate will be te fully charged state and it looks like it stops at 40%. But in fact it is does never get fully loaded.

This issues have already being discussed and sort of already concluded in many other threads, you can make a search.
Just to summarise,
1. Most of them agree it is a battery problem. Lithium Polymer is no good after around 6 months.
2. Few isolated cases of not battery problem which is hardware related.
3. I always activesync with my old spoiled battery (this is just my personal advice as I do not want to risk my new battery). This also avoids USB charging.
4. Charge only when LED is RED (less than 10%) and until LED turns GREEN (real 100%).

Add 2 more O2 XDAs with HW probs
Mine and a work colleagues Execs (bought early Jan 06 under their ****-up £99 scheme) both started to shut down at odd power reserves as in this thread. Both had new batteries, both before and since new batts sometimes wouldn't charge or recognise the power cables.
Also, both have been back to O2 for repairs with the result when they come back, one is in exactly the same state as before, and the other (mine) stck in splash screen. Both came with a note from O2 saying problem found and repaired, and even a QA check slip (ie:evidently no QA - are they pulling a fast one or what?)
Anyways, both are going back to O2 to try again.
If you are in warranty, get it back to them. Wait for the battery by all means but my experience says this is more than a battery problem.
Sorry, thats not what you wanted to hear I know.

Hope you get your Hardware problem fixed, like those cases mentioed in the other threads.
Mine is the battery problem like most cases mentioned in other threads.
My new battery now can goes from GREEN 100% to RED 0% to complete shutdown is possible.
But I normally charge around RED less than 5%.

[Q] Is my battery broken?

Hey all,
I am experiencing something like 5% in 10 minuttes on the phone. I've tried different roms and of course stock. Also different kernels. I've tried letting the phone completly drain it selv and afterwards letting it charge fully before booting up again.
I know the phone has terrible battery, but this is crazy. I use 1% by just looking at it, it seems.
Can this be a bug or is the battery done for?

Have you made Factory data and used Google's stock Android ROM..?
This sounds like Battery problem so maybe it's good to change battery.

How long have you had your phone -- if it's been a long time, the battery might have degraded over time (as most batteries do). If that's not the case, your rom could be reporting battery stats incorrectly. If flashing the stock google rom doesn't do any good, your best bet might be getting a new replacement battery.

[Q] Can a battery go bad this fast?

Hi all,
My SGS3 suddenly since last night has not been able to recharge, battery critically low. I have tried a few chargers, and rebooted several times.
Can a battery go bad this fast, because looks like it was charging and running fine the day before.
Thanks

Have you tried loading a stock ROM on there just to be sure it's not software causing harm to your battery? Not sure if your provider will warranty your battery if it is indeed your battery.
Good luck!

Hi, thanks for your response
It actually is stock rom, sorry forgot to mention it. It is rooted, but I never replaced the rom, just put in CWM recovery. I just moved from rogers to virgin mobile last night, just changed sim card. But the multiple reboots killed a maybe already weak battery?
Thanks

You should download and install better battery stats, it may help you find out if its being kept awake and draining quickly that way

Thanks for your response, necrowakker.
I guess that I forgot to mention as well that the phone was shut off during a recharge, and upon powering up, it still it complaining to plug it into a wall charger.
Like it was never plugged in.

When you rooted your phone was the kernel changed? .. I've had experience with some custom kernels not reading the battery correctly when off, and only after switching it on it still States its low til a little while later it actually looks like its charging .. ( like the battery level goes up over time) while being off the charger.
If thats not the case, try charging your phone again, but while its on after you know its definitely discharged and not just a ROM memory issue. If you turn it off to keep from getting calls during the night switch on airplane mode to keep that from happening. And check if your battery does on fact charge correctly. ...
After 3 full charges and discharges your battery still gives you bother. Then you can either look into what process it was when you rooted,
if it did change anything more than just giving you more access, or see about a hardware replacement, if it is under warranty, and you can take the flash counter back down to zero (if it counted up) and unroot it.
Also using unsupported chargers over the recommended charge rate for your phone, could have done it damage but that's a long shot with today's safety measures on phones.
Edit:
Don't forget to install better battery stats too, just for checking and reporting. Stable ROMs should be able to handle over 300 hours up time before needing a reboot. So using airplane mode should not bother your phone too much

Thanks for all that info.
The phone has been rooted for at least 6 months now. It has been running very good until this morning. No kernel was changed for the rooting. I just wanted titanium backup to work.
I am still presuming that maybe the battery was weak, and when I was changing out the sim card of the service providers, I did reboot about 15 - 20 times to try to get all the services running, maybe that was enough to kill a battery.
Heeter

I've don't some silly **** with powering and charging and pulling batteries for every reason, I can't see Samsung giving you a bad battery if its worked fine for 6 months, you'd probably know within the first 6 weeks if it was faulty. ...
It may easily be a software memory issue with the battery that's confused it. If you are using cwm as a recovery it may have the erase battery stats option on it, if so give it go,
charge your battery to 100, allow it to drop to zero, or til it shuts down, plug in, power it on allow to boot, and leave to charge to 100,
once that full discharge and recharge is done, your battery has its full stats. If it gives you hassle after this point, think about buying a registered Samsung replacement for your phone.

Great, thanks will try that.

S4 Mini battery meter gone crazy

Short story: I bought a S4 Mini GT-I9195 second hand and the battery meter goes up and down like crazy. Thought that flashing Android 4.2.2 will solve this but couldn't do it (auth error in Odin). Rooting seems soo complicated.
Question: Is it possible that the battery meter issue will be fixed if I root/flash a different ROM?
Long story:
I had in the past a device with Android 4.4.2 (Allview brand) and the battery would drop many percentage points in seconds after several hours/days of what seemed to be normal usage. Now, the same happens with S4 Mini, and this made me believe there's a possibility I can make this phone usable by downgrading to KitKat, since I already have a device with 4.2.2 that works great regarding battery readings.
In more details, the issue is that the battery lasts up to one week if I am not touching the phone. The chart (GSam Battery Meter) shows a steady level decrease. When I use the phone however, there comes a moment (ususally around 40%, but not necessarily) when the battery level drops with 1% every 10 seconds.
It can go from 20-30% to 0% in minutes. After I plug the phone, the battery starts charging from 30-40%.
After unplugging at 100%, usually it goes straight away to about 90%.
I have tried already to clear cache, format the battery, so on. I have also tried to flash 4.2.2 with Odin, but it won't take any other ROM then the latest.
If rooting, and risking to brick the thing, wouldn't do anything to solve this issue, I may be better selling as it is, while it is still working at least. Otherwise, I can't use this phone!
Thank you for your help!

I was having same issue. Tried many things (calibrating battery, changing rom and kernel, flashing different stock roms via odin). But none of them solved this issue.
Changed my battery. Bought new battery(Deji). I don't have this issue anymore.

Yes, as umuturunc says, sounds like you need a new battery.

lg g3 battery % is lying.

I know it's a dinosaur of a device but I've got it modded and it's a good phone and works great. Ok what happens is the battery charges and holds and lasts all day but the level indicator says 100% all the time until the phone shuts down. I've flashed stock firmware from 4.4.2 to 6.0 and 3 or 4 different custom ROMs and it is the same no matter what I do. I have seen it show different battery levels in booting up after flashing something or a situation like that but its a unstable reading because of the way it'll fluctuate. So I'm thinking it's a hardware issue. The phone works as it should with the exception of that. It has a original oem lg battery unknown if it's been replaced or it's got some kind of fault. It's basically my work phone my side chic to my Nexus 6 because the SD card storage holds my music so it would be nice to have that working so I know when it's going to die. Anybody else with this issue. Thanks in advance.

Was the battery ever changed? I think it May be related to battery

That I'm not sure of, it's a oem lg battery and it works good and lasts all day, actually surprisingly very good battery life that's what made me think it was internals because if I reboot into recovery and then back out out when it boots it'll say battery is is dead and shut back off, but I'll reboot again OR just plug it in for a sec it'll boot back up with 100% battery life. It never gives a accurate reading. Well I'll order a new battery off e.bay there only 7$ to 10$ for a original lg battery. It's a great phone for what it is with some mods it's fast as hell.
