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.

Battery
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%.

Average battery life on EVO rom

Can I get a general idea of run time for use on a full charge running on latest EVO rom (3.0 ?). Trying to figure what's causing my horrible battery run time. I just got one of those non-oem battery with the blue label that says "FOR HT S620/DASH" . I charged it to a hundred percent and left it alone with 3 tasks running but the screen wasn't on. Came back 2-3 hours later the reading said it was 41% base on CeleTask. I didn't check the standard power management reading. So I'm not sure if it's CeleTask malfunctioning. Maybe EVO rom draining it or bad battery? Does the phone go into idle mode if you leave it alone and the screen black out or is it still functioning until you put it into lock mode(idle mode?). Any thoughts on the battery or other causes would be very helpful. Also Wifi wasn't on.

I have an 1100 mAh battery (supposedly), and the charge lasts around 3-4 days of light use.

What tasks did you have running?

I am getting about 3 hours of standby.... also when I have a full charge and I then turn on the media player or wifi I have about 15 minutes of battery before it shuts off. Then after it shuts off and I plug it in and repower it will say I have 35-45% ....really quirky. I was going to flash back to the earlier ROM and I still may but I seen that there will be a new ROM soon with better battery life

I bought one of those $2 replacement batteries from amazon two weeks ago. My original battery would take a huge dump (98% to dead) in the matter of 3 hours if I turned the wifi on for 5 minutes and then turned it back off.
With my new battery I end up with 82% by the end of the day with very very light use.

Light use on 3.00 + Battery cab.
I unplugged at around noon and it is now 12:38A.M.
and my battery is at 68%
I close apps when not in use and it updates weather every 60min Via edge.
With Moderate-heavy use(Texting, and opera) It will get about 10% by 1:30-2A.M.
Talk time is Decent though Went 2 hours and only lost about 10-15% .
\I have noticed a Concerable Drop in life after updating from 2.80 to 3.00
This is Also on the OEM 1100MAH battery(and I'm also using a little Much of a charger..so its screwed my battery)

Better battery life with a replacement
I'd replaced the original battery with an unofficial replacement, since the original was nearly dead (1 days). This one lasts about 3 days with the new EVO 3.0 ROM.
I haven't done any real measurements , but I feel like I have better battery life with respect to the previous versions.

my test:

I gave the direct link of the product, but probably it expires when I abandoned the site! you have to find the product "S620" on search box

for me everything is fine I'm using the original battery, 3VO ROM with Arabic for WM6.5, many tasks opened most of time and the battery is just fine and hold for 2 or more days..

My battery life

Hi, I am noticing that my battery life is very short. I have to charge my phone atleast twice a day. Last night I watched a program on my phone which was forty minutes long. After that my battery was already 60 percent about. However.now, in the morning, I woke up and checked one thing on the internet by 3g and now my battery is already 40 percent. Why is this .... I know that battery life on here is not good but mine seems worse.
Is anyone getting the same?
Thanks in advance.

Tell us your settings:
- Do you allow background data?
- Do you always synchronize?
- Do you enable data connection?
- Do you connected to the Wi-Fi all the time?

I swear my battery life is far far better since i put that Generic rom on, maybe the minor updates htc have released help battery life ?

Maybe the update will fix the battery life issue? We'll see when it rolls out on t-mobile handsets.
Other people have reported excellent battery life (mine only arrived today) and it seems to improve over time. How long have you had it?

I had mine 1 week today was originally on the T-Mobile rom and have had terrible battery life up to even yesterday, updated to the Generic Rom yesterday and it honestly seems to last longer now.

I was waiting for someone to report this before I did .. I too was originally on the T-mobile ROM and updated to the Generic ROM. I didn't notice any increase in battery life. In fact I didn't notice any changes apart from the minor T-mobile branding having gone.
Yesterday I did the OTA update and again didn't notice any changes. I did this morning though, in 10 hours the battery only dropped 4%. Of course the phone hadn't been used in that time and I have wi-fi and bluetooth switched off but I am sure this is a lot better than I was getting.
Maybe the OTA update has improved battery life. Let's hope so.

Hello again,
Is the generic Rom the Rom without the T-Mobile stuff?
How would you get that? And would that remove your warrenty / insurance?
How have some T-mobile people get the OTA update whereas some have not?
Have you realy found a difference with it?
THank you

Yes to without T-Mobile stuff.
You can download it in the Android Dev Desire section on here. There are extra steps to take.
It WILL void your warranty.
Anyone that got their phone direct from T-Mob will NOT have it unless they did it manually. And by that i mean manually flash generic rom then update.
I noticed my battery is better but it's only one day. And i never really had a problem with it. I charge once a day anyways.

Thank you for the help.
However I am unsure if I should get the generic ROM.
What are the other advantages?
Because there is not a lot of T-Mobile stuff on there.
If I got mobile insurance with T-Mobile and flashed the ROM would I be able to claim if my phone got damaged or lost?

Advantages. The phone is as it would come straight from the manufacturer. You will always receive updates for the device before Vodafone, O2,T-Mob etc would have them ready.
If the phone was lost then yes. If damaged...probably not but if it develops a fault you can always drop it in a drink and claim on he insurance...bit dodgy like!

My battery life story
So, I downloaded the brut Google nav mod the other day and haven't had a chance to use it until today. Took a journey which took about one hour, and made sure that my battery was fully charged before I went. I still hooked up the phone to the car charger though, to save power. One thing I noticed about charging the desire, however, is that if it identifies the battery as being already full when you connect a charger, the indicator light stays green, so doesn't top up even when you have been using it for a while. I noticed this about 20 minutes into my journey by which time the battery must have gone down quite a bit. Removing then replacing the charger sorted the problem and the Orange light indicated that it was charging again. By the time I got to my destination the battery was at about 50%.
On the return journey, I hooked up the phone again, turned on Google nav and set off. About 30 minutes into the journey I stopped off at a petrol station to grab some snacks, checked the battery and read 17%! Even though it was supposed to be charging the whole time!! I then got a message saying that the power from the car wasn't enough to charge the phone and I should attach AC power ASAP, which I obviously couldn't as I was in the car. I ignored it, got home safely enough, disconnected the charger and then watched the phone die .
Ok, so I was using gps and 3G which clearly uses up power and I guess Google nav is fairly processor hungry, but I would assume that having it connected to the car charger would be enough. Coming from a tocco ultra, I'm used to rubbish batteries, but at least that would charge up in a car.
Don't get me wrong, I still love the phone, but I just need to know if this is gonna be a regular issue, or something that can be sorted out with a Rom update.
Just for info, I've had my desire for nearly a week now on TMO using the old Rom. And, the car was Passat estate which is in very good nick, so I doubt that was the problem.

I would look if the charger really charges the phone or if it drains it also when not using GPS/Nav etc.
Reason I'm saying this is that I once bought a charger that actually drained the battery instead of charging it, while it worked fine on my older Nokia phone. I'm assuming the phone deactivates some power saving features because it thinks it's hooked up to a charger, but at the same time the charger is too weak to actually charge it.

I have not used branded rom before on this phone but the htc rom battery life is fine. Mine has been going for three days with usage fine

intresting my battery last a day

I just started charging 2nd time my battery and it lasted hmm since about 2pm till 15% at about 00.00 which is pretty much 10hours of heavy use. i did leave it on sleep for about 2 hours though and i left it at 25% and after that it had 25-24 % lol so if you turn all the updates off it will last quite a lot i guess

I rang up T-Mobile today (tech support) to ask about the lack of update considering the rom was behind the non carrier phones at the start and then an update too. They said they do work on them when they see a notable difference worth updating.
Anyway, I also said I was incredibly dissatisfied with the battery and how long it lasted and wondered if it could be to do with the ROM being well behind the stock HTC one. The tech support guy was excellent and very helpful. He said that with the type of battery in the Desire, you need to make sure you have it on a MAINS charger from quite low for a good couple of 14 hour sessions with the phone off. This builds up the charge for the battery and you should see a marked improvement. He said that most people don't bother to do that and as a result get poor performance.
He did say him and 4 members of his team have the same phone and while some of his team had battery issues he didn't. The main reason being that he had spent a few days not taking it to work and running it down in the evening then giving it three 14 hour chargers. He said that made a huge difference.
He also said if I was dissatified to a point of big frustration they would replace the phone or refund. Can't ask fairer than that

[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
Sent from my T-Mobile G2 using XDA App

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.

Phone shutting off at 35% battery level

Ever since I upgraded to Marshmallow, the phone is shutting off at 35%.
If I plug it into a fast charger it'll start back up. Non fast charger forget it. Battery shows 35% when I plug it in to charge.
Took it to Best Buy after speaking to an AT&T tech. The Samsung rep at BB, said he ran some recovery software to check for missing or corrupted files associated with the upgrade. It appeared that they just reinstalled the 6.01 update.
Anyways it did nothing and the Samsung tech said I could try doing a factory reset or maybe try a new battery. He then said that if the problem started after the the MM update, then that's the issue. He mumbled something about the phone just wasn't able to handle MM blah blah blah.
ATT offered to ship me a new phone with a working upgrade.
Before I go that route or try a factory reset, I thought I'd check here for other ideas.
Not happy with the phone since the MM upgrade. Along with the phone shutting off issue, it's shutting off while charging on my wireless charger, phone screen is screwed up in landscape mode and doesn't show any of the buttons that show in portrait mode.
Is there a battery calibration app that will run on this without root?

I'm a computer tech, with a VZW N4. I popped over here to see if I could help a friend with the ATT N4. Looks like he's stuck without root, but saw your post and decided to reply.
I always recommend installing 'Battery Left Widget' from the Play Store and use it on the main screen. If you want to test the battery... do the following. But I'd recommend getting a new battery. It's most likely the cause of your problem.
Go to the settings and change the 'Discharging Widget Man Text' to "Estimated Battery %". The other settings can be as you wish, but I prefer the 2nd to be time remaining and 3rd to be time dead. Do the same for the charging options.
Let it calibrate for a few days. If you see a big discrepancy between the system battery (in the top right) and the widget, you've got a dying battery. Buy a new one. My Verizon version of the Note 4 started dying at 22% and rebooting. Dying battery was the cause. I knew this because it would read 72% in the top, but 42% in Battery Left Widget. And when it would get to 5% in the widget, it would start rebooting. The other battery at the top was reading much higher. A new battery fixed my woes. However the OTA upgrade to MM did a job on the battery too.
One word of advice ... turn off Fast Charging. It probably killed your battery in the first place. The original Samsung chargers will still charge it to full in a couple hours, but Fast Charging does something bad to the batteries, and they don't last as long. I know, I've had a Note 4 since day one, and I'm on my 4th battery.
A note about MM upgrade. I have to say, I wasn't a fan either. My battery didn't last as long on MM as it did on LP. The tricks about doing a full wipe didn't help. The only fix was to get my VZW model rooted and I regained control. Now I have a MM rom that actually works well and gives me 15 hours a day of usage, 3+ hours of on screen time.

What rom you are using anyway. I have changed my battery and switched to miui 8. But problem remains same with an extended battery life... But mine won't charge more than 67% and shut down @ 12% with a SOT of 3 hours and above.

I would try your battery in another device, just as a test.
Well ... mine is a VZW Note 4, not AT&T. I've used multiple roms over the past few months. I don't know what type of extended battery you are using, but if it's the ZeroLemon, it may need a better kernel to work with it. The phone doesn't know about extended batteries without additional instructions, so charging and time to empty can vary.
I just know I will NEVER buy another Samsung battery from anywhere. I think 99% of them are fake. I went with an Anker brand and it's been perfect.
Currently, I'm running MODest v5 ROM. I just installed Nseven on a 2nd device as a test. As for the MODest ROM, after only a couple of days of testing, it looks like I'll get even better battery life than I did with PaulPizz v2 (over 16 hours of heavy use compared to the 13 with PaulPizz)

Thanks for your quick reply... Im using samsung original Stock battery and there is sticker of smart care and it is from a samsung showroom
So no idea its original or not.. Should have been original... My note 4 SM 910S SK tel korian version so the rom options are very limited. Do not have any warranty period left so im confused whether i should go for a hardware checkup... Anyway im pissed of since the marshmallow arrives....the problem started right after that update.. Since then i have changed rom changed battery.. So now i guess i have to change the phone finally... Anyway thanks for your reply..

I have the same problem with charging to only 67%
If you take out the battery it will continue charging to 100%.
All this cr*p started when updated to MM
Going back to stock 5.0.1 and doing the #*0228# reset should help.
And samsung batteries are a disaster, even the genuines ones.
