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.
Joe

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%.

Battery issues

Ok, this is just plain frustrating and I have no clue about what to do.
The lifetime on my phone is dropping ridiculously fast. I replaced the original batery (that used to get ran down pretty quickly, about half a day, without using the phone much) with a spare battery a friend gave me (it's from a different model, but a minor modification it fit perfectly. For a while, it worked somewhat more decently (although should I have used the phone, I'd lose about 1% for every 30-45 seconds of usage). But for a couple of days, it started wearing down a lot quicker as well.
For instance, just charging the phone and then leaving it without actually touching it on the desk will leave it at 88% battery life within about 30 minutes.
I've checked the processes to see if there's anything out of the ordinary, but everything seems fine. I'm thinking maybe the battery may have gotten damaged in the meantime since it wasn't the designated model for this phone, but I'm having serious doubts.
Also, I've ordered a new battery which should ship any day now. Hopefully it will solve the issue, although I'm considering getting a new phone.
Any ideas?
Also, the old Asus that I used to have (WM 6.0, standard keyboard) still has an amazing battery life, at least compared to the HTC (it can do about 3-4 days in standby, and 2 days with normal usage. Also, it's able to run for 12 hours while playing music and occasional web browsing. I can barely squeeze two hours of usage from my HTC)

Maybe you should get a new and proper battery to your device, maybe your fix does not work anymore. Also you can damage the excalibur motherboard if your messing with different volts from batteries design for other phones.

Well, the battery voltage is the same. So is the pin layout (well, that was pretty self implied). Both batteries are manufactured for HTC phones.
I guess I'll find out when my new battery arrives. However, my phone has been acting weirder and weirder. SD card issues, now the battery... And on top of that, I wonder if the two issues are related.
Edit: also, will the charger output make much of a difference? Say I use a 500 mA charger or a 1000 mA one.

Issue solved. Apparently it was from the SDHC patch I had installed a few days before. Removing the patch did not solve the issue (also, the patch disabled my WIFI) so I proceeded to reinstall WM on my phone. Now it runs fine, with regular battery drain.
I think the patch may have not allowed the CPU to enter idle mode. I can't think of any other explanation.

nah its definitely ur battery. i had the same problem, its that ur battert has degraded and it has become unable to withstand its charge. just call ur phone carrier and tell them. the should send u a free battery.

I know some HTC batteries are the same voltage, but why do you think they make different ones especifically for every model eventhough they have the same voltage.
Just to let you know and regarding the output charger; I did a little experiment once, with motorola chargers (V3) since you can charge your dash with them but I tried to charge the exact phone (motorola) with the original HTC output charger.....and it didn't charge at all.
After months of using the motorola charger I started to realize my battery was not working well in my excalibur and in a period of 4 months my battery didn't hold a charge for more than 3 hours. I bought a new one and I strictly used the orginal HTC charger.
My battery is 9 months old now and works like charm (2 days + hours) with the latest ookba 3vo rom.

[Q] Terrible Battery Life - Hardware Fault?

I've had my new desire z about 2 weeks now, and am utterly dissapointed by a frankly dreadful battery life.
It's my second DZ, given the original was nicked, but (kicks self) wasn't insured, so was purchased from a supplier that shipped my phone from Hong Kong (I live in UK, and the new phone is an identical model, except for a slight difference in key layout - A2727 I think is model number)
The original phone would give me over two days life with very low use, which i considered to be fair for a decent smart phone.
The new phone barely gives me 10 hours with no use. I've done a couple of tests - unplugged it at 2am, but 8am it's at 30% or lower. This was done with all data connections turned off.
If i leave the new phone to go dead then that's it - it won't charge. The only way i've found to get juice back into the battery is to hold it in my old touch-pro 2 until it's charged enough to charge from the desire.
Last night was the clincher. I've gone out with some friends to the pub. I had a conversation over it, and checked my battery life - 42%. As a last dith effort i factory reset the phone at that point to rule out a mischevious app, and checked - 39%
Within 2 hours, and with no use at all that was down at 8%. In order to avoid the charge issue i cut my losses and turned it off at that point. Once home (oh, about 4 hours later maybe) I was unable to turn it back on. I then left it plugged in overnight, and was still unable to turn it on this morning until i'd done my cross-phone charging trick.
I'm now entirely convinced there's some form of hardware issue at fault here, so i'm wondering if anyone else has had the same problem with this phone before? I see lots of thread regarding poor battery life, but most seem to be solved by turning data off or some rouge app, neither of which are an issue in this case. Also, any hints for making my life easier when I phone HTC tomorrow? I've read elsewhere their support might not be all it should be.
Thanks in advance for any help! I've ready to pull my hair out as what is a fantastic phone otherwise has been completely ruined by this battery issue.

I think you should get a new battery to rule out that the battery itself isn't a problem. I had similar issues with my G1 a while back and it solved a lot of wierd, seemingly unrelated problems. Batteries are pretty cheap online, $15 or so and some are free shipping.
The way that I figured out my battery was toast was by comparing it to other batteries. it had a bulge in the center where it should have been flat. Fingers crossed it isn't hardware.

had already tried a diff battery (did you know you can chew a corner off a touch pro 2 battery and make it fit??) Which i know worked fine in the old nicked dz and imo as i was getting same issue ruled out battery problem.
anyway... phone has now been returned and i'm waiting 2-3 weeks to get it repaired under warranty (though am hoping for complete replacement obviously)

Chewing on batteries has got to get you extra xda brownie points. I'll remember that

I'd like to think there was some techincal or engineering skill in there somewhere.
but it was mostly "Well, apart form this nugget of plastic they're the same shape..."

I'm having the exact same problem... When you take you shutdown to recharge a dead battery, does it sometimes try to turn back on? I left my apartment like 30m ago with 100% battery, and I'm at 84% and declining. There's nothing running. And I've replaced the battery, same issue.
I think I might just RMA this one.. seems like an engineering issues.
Edit: I'm the 40 seconds it took me to type this, battery dropped to 82%.

Wanted to bump this post. I've since wiped / reloaded and wiped battery stats. It's still jacked. I think it's an internal electrical thing. Reason is: I'll power down to take the battery out. When I put the other one in, it'll turn back on. Or if I power down to charge, it'll turn back on - plugged in or not. I don't want to deal with the RMA process again, but I think it's my only choice. I've taken two phone calls this AM @ 100%, and it's at 96% now. Drives me insane. Ugh... I'll call TMO. Anyone know if the replacements are still rootable?

So... I had my phone replaced, and it's still doing the horrid battery thing. Flashed CM 7.1 RC3 or w/e the latest is, cycled one battery - and it drops like a stone. I have two chargers (one at work, one at home) and they both charge the phone up to 100%. But it's still losing battery life quicker than I'd like. I used to be able to get a good 18 hours out of this phone. Even with a new battery and a new phone, it's acting up. I'll try to flash an older ROM and see if it's the same thing. I updated to #130 nightly from 7/10. We'll see how it lasts today. But I do remember I had horrible luck with CM's ROM's on my G1. Battery would just drain for no reason. The main process taking up the most battery life is "Cell standby" so I changed to the latest radio - and it still drops. OP - have you figured out your problem? I've removed a ton of apps, and it's still messing up. I listen to music for... 45m in the AM, and I get down to 54%. I've formatted my SD Card as well.. it's driving me insane.

I just flashed CM 7.1 a few days ago and while the ROM is great, it does seem to be a litter harder on my battery than 6.1 was. With light/moderate usage yesterday, I got about 16 hours and that was running the battery almost completely dead. With heavy usage, I get about 10 hours and need a bump charge in the afternoon.
You might want to look into getting a Mugen 1800mah battery. You can get them on Ebay from 35-40 dollars. The seller 'nakedcellphone' is based out of Southern California and another user has confirmed ordering from them and getting a legitimate battery (lots of fakes on Ebay). Either that, or carry a charger with you...
Have you tried using Watchdog to see if there are any 'rogue' apps that are causing the drain by running in the background? What about going to spare parts > battery history > Partial Wake usage? There it will show apps that are draining your battery when you're not 'actively' using your phone. For me, the Android System is the highest drain in that menu. Good luck! Hope some of this helps!

I just checked spare parts, and there's nothing too odd in there. Just my music app. And I've changed that too - thought Winamp was killing me. I'll check Watchdog. This is a brand new OEM battery along with an RMA'd G2. It has to be the OS / Radio or something. I've stripped like every non-essential app too.

faulty battery after 1.5 year of usage?

hi i have G3 32GB for about 1.5 year i had no reboots until 3 days ago when they started. I had two to three reboots a day mostly when answering calls shoud i change the battery?

Ive seen the batterys go out completley all of a sudden a year ago so from the standards ive seen with this battery ure in good shape try booting into safe mode for the day see if its a rogue app or tweaks if ure rooted

Last month the same happenend to me. Constantly reboots. Your problem will get worse and worser. Battery was only 1 year old. Ordered a new one and problems are gone. Juste get a new battery!
Regards

Had the same trouble with an S3 Mini, went through 3 batteries within a few month. Though it was a known issue, though not such a widespread problem with different brands of phones I don't think but yeah random reboots are a sure sign of a dud battery. Do the spin test on a flat, smooth surface. Not sure how to do this?
1: Remove the battery from your phone after turning it off & unplugging it.
2: Set it face down on a flat, smooth surface and spin it.
If it spins like a top it means it's bulging and thus a dud and you should replace it immediately with an official branded battery direct from LG to ensure maximum lifespan and authenticity.

Old Pixel XL and weak battery performance - old battery or something else ?

Hello
I bought a Pixel XL some years ago (2017 IIRC). Been a great friend so far, though the little internal storage is starting to show.
Anyhow, the battery performance/duration is really not that great. It will go from 100% to 0 in 8h or so. Usually it will shutdown itself around 30%.
Battery charging is erratic. While charging being off, and after showing full battery, i turned it on just to find it after boot with almost nothing, shuting down little after.
The device is warm to the touch while in standby, but not always. It's running the official version from Google, though the partition size has been changed and the device unlocked.
So, old battery needing replacemente ? Damage hardware ? Worn out silicon? what are your thoughts?
Thank you in advanced.

A battery failure seems very likely.
Replace before it damages the phone... go from there.
