Hello,
I need your help with the following problem:
I have been using my Jasjar for 5 days now and I have a problem with the battery.
As soon as it gets to 35-40% battery power the unit switches off without any notice.
The only way I can turn it on again if I put it on a charger, and than it turns on again like after a soft reset.
I installed the latest ROM from the clubimate but none 3rd party applications.
Please let me know what can be this problem.
Thanks,
Zsolt
same problem here
Hi Ronaldovic,
Have you tried with another battery or just the original?
I was advised to change the original battery as that might be faulty but I couldn't get a new one yet.
Zsolt
For the O2 XDA Exec the battery has a 6 month warranty. You should check the situation with the JJ
battery issues..
I had similar issue and also where on switch on the screen light goes off and back on. This seems to be linked to battery chargin "top-ups" therefore sometimes the supply from the battery is not continously smooth. Try fully draining your battery and charging fully
I have same problem with my Exec. Any solution ??
I buy new battery but...when it gets to 25%, still switch off. So I dont think it's error of battery, may be it's bug of ROM for Exec???

1 month ago I have same problem. I think is not battery.
I make upgrade by all the ROM (JAS JAR, QTEQ, MDA PRO ecc.) but the problem I have not resolution, and 2 week ago my pda (MDA PRO T-Mobile) go in htc warranty.
Sorry for my bad english.
I have also noticed this problem a few days back. My Jasjar switches itself Off when the battery goes down to 22%.
I never used to have this problem when my Jasjar was with the original factory installed ROM version which was 1.13.53 WWE, Radio 1.03, ExtRom 1.13.137 WWE. When this ROM was installed I used to get the first low battery alarm at 20% and when the battery went down to 10% the screen would dim out and the SD card would deactivate, but still the unit would not shut itself out.
I installed the updated ROM when it became available in March which is 1.30.76, Radio 1.09.00 and ExtRom 1.30.164 WWE.
I am not too sure if the problem is linked with this ROM as I usually never allow my battery to run that low. However a few days back when I forgot to charge my battery I noticed this problem. I repeated this deliberately a number of times and each time the Jasjar shuts itself off exactly at 22%.
Just wondering if there are any solutions yet.
Regards
Same here, device just dies @ 26%. Was going to buy a new battery, but that might not resolve it?? *sigh*
RE
This battery issue has been discussed in two other similar threads.
In my case I just changed the default battery to a OEM one and everything works fine :lol:
Isn't the default battery an OEM battery? I'm tempted to buy one of the 1750 mAh batteries off of ebay (original JasJar battery is 1650 mAh) - is that a bad idea?
Try overnight charging of the battery for one or two days..this will solve yr problems... :lol:
Hi,
hard reset to your device, don't forget to get backup contacts, sms and data.
battery issue
I've had similar issues. Screen goes blank when battery low, plug in to charger and all is ok. What I've found is sometimes, not always, the battery screen brightness has gone to 0, but on-mains is set for full brightness. I never changed it, so maybe the device is trying to save power itself.
MNB.
Same here. My Jasjar dies sometimes when the battery is on 60%, 50%, 30%, 20%. etc. If I use the internet or camera or something then it will go dead, but not everytime.
Sometimes I can use anything and it will last till about 10% when the SD Card disables, then I charge it.
Don't know what to do. I don't want to buy a new battery if I'm not sure that is the problem.
Yes the same on my O2 Exec. Crashes at around 32% no matter what. Only remedy is to put it on charging again.
This started after I upgraded to the lastest O2 Rom; prior to that there was no problem whatsoever and I could go down to single digit battery percentages without any issue.
Is it the new ROM? Is there any work around to this malady?
Thanks to all who reply, in advance.
Cheers.

-----------------------------------------------
So can we say that downgrading does not fix it, or removing certain software combinations?
has anyone actually proved that replacing the battery works or not?
With the issue this widespread (and across carriers) has anyone tried to contact HTC about this? I still have my doubts that this is ROM related, seems more likely to me that many of the initial batch of batteries have gone bad.
My battery is on order with expansy. Expect it in the next 4 to 5 days and will definitely let you all know of my experience with the new battery
Regards
I have an XDA Exec and I have just upgraded my ROM to the newest QTEK version. Since then, I have noticed that it crashes and reboots when the power level showing on the power meter reaches about 25%. I don't believe this problem was occurring before the ROM upgrade.
Although it stops working when 25% power is showing, I do not think that the battery life is actually reduced at all. It seems to me that it is more like the guage is inaccurate now and the power is really near zero when it crashes.
I wondered if the power guage needs recalibrating in some manner after the ROM upgrade because the settings have been lost. I know that some laptop computers need their batteries to be calibrated on first use. Does anyone have any ideas or information on this?
Thanks
Mark
Mark,
did you ever solve this issue? I have the same problem. Thanks for anyone's help.
Have only just noticed but im having the same problem to so annoying
Bad news, I am afraid. It is a harware fault and needs a repair.
In the end I returned my Exec to O2 under warranty. I got it back last week but they had forgotten to return the battery. After a phone call they sent me a free brand new battery by next day delivery.
Unfortunatelyt this means that I can't say for sure whether it was a battery problem or the phone itself. The covering letter with the phone said they had found a fault and repaired the phone, but since it seemed to be a stock letter, I can't be sure.
Anyway, my Exec certainly works fine now. I can get down to less than 10% with no crashes. I definitely did not have anything to do with the ROM upgrade.

Mark,
Thanks for the reply. That was not what I wanted to hear! I am going to continue playing around with it; I can't believe we're the only ones to have this problem. Let me know if you get any more news. I'm getting tired of sending the HTC in for repairs.
i-mate crashes with battery in less then 43%
My i-mate continues to crashes with the battery is less then 43%, apparently the problem occurred when I make the upgrade to ROM Qtek WWE_13077_130176_10900, was looked like that this version has something that change the battery configuration, since Qtek 9000 comes with 1750 battery mAh? I reinstalled the i-mate ROM 1.30.82 and the problem persists?
I made a test leaving the i-mate on, without using the radio until the battery settings showed 23%, then I made a phone call, the i-mate crashes in seconds. Somebody could inform what is the true voltage of the battery in the i-mate when it is 100% and when it is 10%, at the Main Battery settings?
Battery problem...u ccan verify this by using a differrent one may b from yr friend...
I have the same problem, its only started happening after the ROM upgrade from o2, before it would run down to 0% no problem but now it gets to 25% crashes and i have to reboot it and turn the backlight of otherwise it crashes again. Are you sure its a battery problem because ive had the same battery for 6 months and the problem only started after the upgrade.
Thanks to all of you guys for adding comments. Good to see others with the same problem. Misery loves company.
Anyhow, I can't exactly say my problems started with a ROM upgrade. I have two used universals. Here's my story:
PDA#1. Upgraded with previous Orange ROM as soon as I bought it and started having the 25% crashing problem
PDA#2. Never had crashing problem, upgraded latest Orange ROM, down to nearly dead battery today and no crash.
Hmm, to test the bad battery theory, I will swap the battery in PDA#1 with the battery in PDA #2, and if I get a crash, I can blame it on the battery. Otherwise, it's the OS. Both PDAs have EXACTLY the same programs installed from fresh ROM upgrades.
Battery test
Hi PDAholic.
Which was the result of the test with the battery.
Hi
See my previous post in this topic. I can confirm that my problem seemed to start when I upgraded to the newest QTek ROM (from original O2 ROM). However after it has been returned to O2 for a repair, I have once again upgraded to the same ROM and now it works fine.
So, it must ether be a hardware fault on the Exec or a battery fault. My evidence is not consistent with it being something to do with the ROM version.
Anyone have definitive information on this problem?
Mark
Mark: I thank you for your post--but you have to admit, there is nothing wrong with a little experimentation!
Josedias: My experiment is still underway. I will say that taking out the nearly dead battery from non-crashing pda and putting it into the crashing pda did not result in the latter pda crashing. However, I am now waiting for the battery from crashing pda (which is now in non-crashing pda) to die. If it does, the problem is the battery. I actually have another theory if none of this pans out, which I will present with my next post.
Pdahollic
Will be good to hear what your fndings are.
I spoke to o2 today and told them about the problem with the battery they tried telling me that it was software related then i told him that i was using the latest software from there website and he was like hmmm ok let me put you through to returns. Got put through and the kind person that i spoke to there said just to pop it in the post with the returns number and will send you out a new one the same day.
So i should hopefully have a new 1 by the end of the week will let you know if i have any problems
Okay, interesting results here...
I was actually unable to reproduce the shutdown on either PDA, with either battery!
I have a theory why, and perhaps those of you with the problem could try and see if it fixes your devices.
When I started the experiment, I wanted both PDAs to be as equal (controlled variables!) as possible. So, I charged both overnight until the green light came on, then did a soft reset to both PDAs. I have a feeling this might have somehow reset the battery meters in both devices.
Pretty much all PDA manufacturers recommend when you first get a device to charge it to 100% then begin using it. I do know that when I did the ROM upgrade on the device that kept crashing, my battery was very low. So, I presume that when I started using the device, the battery calibration was way off. Say that the device thought the battery was at 100%, but it was actually only at 75%. When the battery discharged to 0%, the device thought it was at 25%, and thus did not issue any warning messages. Then, without warning, the device died and would not come on without charging (which is what mine did).
I don't know for sure if this is what has been happening, but it makes sense to me.
My next experiment would be to stick a near dead battery in a device with a fully charged battery and see what happens. Although, at this point I probably "ought to leave well enough alone."
Again, I suggest to all of you to charge the device overnight to 100% WITH THE GREEN LIGHT ON, then do a soft reset and see if your problem is solved.
I will keep you guys posted on any further problems. Good luck.
Hi everyone!
A bit out of topic but I could not find any other discusion that could relate to my problem which is also related to battery.
I've got this guy who bought a brand spankin new XDA EXEC straight from Taiwan and the lame ass used it for about 4 hours without preformating the battery until it seized on him. It happend at the time of Active Sync instalation.
It did not die out sooner because he had it connected all the time to PC via USB cable thinking that this will charge the battery.
Now all he can see is the O2 welcoming screen and the ROM initialization figures.
Any ideas guys? I feel sorry for him and am trying to help him somehow.
I presume he has tried to do a hard reset (both softkeys, reset button and power). If that doesn't work, he could put it in bootloader mode, disable USB, and try reloading the ROM. Make sure he realizes that it takes a LONG time to soft reset the Universals. A common nube mistake is to keep hitting the reset button thinking it has locked up on the splash screen. Not that I would ever have done that...
I received a T-Mobile MDA Pro on tuesday and it has the same problem - but, my battery seems to die at 50% and will only power back on when the charger is plugged (mains or usb) in?
Hi guys ive just been on the phone with o2 and i have been told that it is indeed a hardware fault and that i will be getting a new one back from them in the next few days.
Qtek 13077 ROM ????
Could somebody inform what is the true voltage of the battery in the i-mate at 100% and when it is 10%, in the miter?
I have charged the unit till 100% led = Green, then soft reset, the problem persist?
Now I am 100% certainty that the problem occurred when I made upgrade to Qteck, we needs to investigate what the the Qtek ROM this doing with the JasJar?
First off, I have seen many threads on the MDA PRO (and all its variants) cutting out at high battery power levels and from what I can see there doesn't seem to be any concrete resolution. But here is my situation.
I bought a new sealed MDA Pro and immedialy flasshed to the latest T-Mobile rom. Thats where the problems began. I seem to be plagued by the MDA cutoff at 60-70% problem.
The way it manifests is the radion loses signal and cannot locate the carrier at or below 70%. At this stage a reset of the device and it reboots but as soon as you use the phone or wifi it crashes .. black screen.
As with others if I connect the USB cable and charge by PC or mains everything returns to normal. Not a very mobile solution!!
I have tried every variant of ROM out there and the problem remains. I have charged the battery for 16 hours etc etc. I have tried phone in Auto, GSM modes .. same problem :!:
The only thing I haven't done yet is buy a new battery and hence my post.
Will the purchase of a new battery solve the problem? As with other threads it would seem this came along with the latest roms. Does flashing a ROM when the battery is less than fully charged cause problems?
On a final note, if after the radio loses signal it is turned off I have been able to run the device down to 20% running videos and MP3. Is this a probem with radio levels above1.09.00 (Just thinking out loud)
HELP: This device is perfect for my daily use and having purchased a less than mobile device I am now close to getting rid .. but I dont want to
Any advice greatly appreciated... expecially from those who have fixed the problem.
I had this problem and a new battery fixed it.
Thanks. Look slike a new battery
There seems to be different speculations on what causes the battery problem on the Universal: the power charge cable quality theory, one idea about the battery level stored inside the batter which some claimed to registry heck could change and another idea about the battery 500 charges limitations.
But if yours is brand new, then none of the above applies... So the refresh to a new Rom definately must have something to do with it. Wonder anybody who had bought a new replacement battery after the power drop had done another rom refresh and whether the same problem returns?
I have just bought a replacement battery (1800m Ah at standard size by MoMax which gives me another 30% more power everyday which is something good I got from paying for a new battery) yesterday to change the old one out for the same reason. Looks like until someone found the real cause, I am keeping the old one for my next rom refresh...
New Battery ... problem resolved.
my mda says that it has like 93% battery life and while im scrolling around on the web after 15 minutes the phone just automatically SHUTS OFF and restarts saying low battery life and then it dies again. whats the deal with that? what do i have to do to fix this? its sooo annoying. any help will be greatly appreciated!
you might be out of RAM..
close some apps that are running..
IE eats up a bunch of RAM..
Looks more like a faulty battery to me! OUT OF RAM or LOW RAM never will give out the message: LOW BATTERY.!
If you have the chance to try another battery (maybe you own a second one or a friend might have the same device) just give it a shot ...
i tried with a different battery. the phone still reboots if your on the phone or interenet for longer than 10-15 mins. whats up with this?
I have EXACTLY the same problem with my phone. This phone is onlt 1 month old and was a replacement for a previous MDA that had SD card problems...
I have the exact same problem. When I don't use WiFi the battery lasts for several days. But when I use Wi-Fi in 10-15 minutes it restarts and shows battery very low.
I have noticed that if I connect and immediately disconnect the charger, it shows that there is a lot of power left in the battery and the phone will actually last a while. It definitely can't charge it so fast, so somehow its getting confused about how much battery is left.
Can anyone help with this, please?
I just did a clean install of the official T-Mobile Rom, and the problem is still there. The phone keeps restarting.
Help please.
right there with you guys. ihave and 8125 and they same thing happens i am just glad i have a spare phone. Bad very BAd.
Guys
Junner2003 is right. The problem is a failed cell in the battery. If you don't put the wizard under any load it will last for a while however as soon as you ask it to do something (like use the internet) it dies real quick.
Get a new battery (not a second hand one that you know nothing about) and the problem will go away. I had the same problem a few months ago and went through all the same issus mentioned on this forum but a new battery solve the issue once and for all.
Thanks for the input, jt_armstrong. I'll replace the battery and report back here. I am thinking I about getting a high capacity one like this one
http://cgi.ebay.com/2400mAh-Ext-OEM...ryZ15034QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Hey everyone. jt_armstrong and Junner2003 are right. At least in my case changing the battery seems to have solved the problem.
I got the high capacity one from ebay, and so far it has been working perfectly.
I don't even know why did I update, 1.43 worked fine for me. After I installed 1.48, I've noticed several problems:
- battery drains a lot faster
- problem with the auto lock, or lock with "end" button - after I want to use the device again, it won't turn on all the time, buttons glow, but nothing happens
- few times phone didn't wanna dial some people when I enter their contact and try to dial their numbers
Anyone experiencing similar issues? Both versions of ROM (1.43 and 1.48 are WWE East Europe)
can't be that I am the only one facing these problems in 1.48
hehehe seems u are tryed to flash 1.48 a second time?
I seem to be having a problem at the moment with 1.48 where sometimes (usually) if I plug in my phone to the computer it freezes up. Only way to solve it is to take the battery out.
Don't know if it's to do with 1.48 or some other program I've installed. Doesn't seem to do it all the time but it really p!ssing me off. That battery cover isn't easy to get on and off. Why on earth didn't they put a small reset button somewhere like on my trusty Trinity.

I reverted to 1.43 WWE East Europe, downloaded from HTCPedia, but seems like battery is again draining a lot faster than on my stock ROM. I don't know what whas the catch in my stock ROM, the one I got when I bought the phone, but seems like battery was far best on it.
It was 1.43 WWE East Europe as well btw, I have no clues..
the problem with battery is with htc sense. You can notice this disabling it for a day and using the Windows default. It is a huge diference
Im using 1.48 official and not get any special problem....
Yes, sometimes after reboot my device I not get lock of screen. But if to do long press of OFF button and choise LOCK then all works fine. Also, I have problem with Skype, but it not special problem, I think.
Battery works about 1-2 day with my style of using device. It mean 1-2 hour of speech, WiFi when available, Inernet browesing and checking mail every 10min. I think, this normal.
With 1.48 I have more faster connect to WiFi, more stable connect in GSM and more natural sound.
May be, I will reflash my device to 1.43, but now Im happy from 1.48.
i have the same battery drain with 1.48,
back to 1.43
I have similar problems. 1.43 was working great for me and I thought I could get a little more out of my HD2 with 1.48. Turns out not. Battery life has decreased, the phone crashes every now and then (as opposed to never with 1.43) and the camera takes horrid pictures with the flash. I am thinking of reverting back to 1.43. I am using the Western Europe ROM.
I will now wait for official HTC roms before installing anything.
Sure you can disable Sense and have huge battery life but that sort of defeats the purpose of the HD2 in my opinion.
Bear in mind that WM seems to take a little time to 'calibrate' the battery with each new ROM. Various threads I have read suggest anything from 2-3, up to 10 or more battery drain/recharge cycles before you get a true reading.
Ditching a new ROM after only a day or two may therefore be a little previous...

Strange with 1.48 I can take really great photos which I couldn't with 1.43. My phone since I have flashed it to 1.48 never hang/crash but battery drains very fast.

I had also read something like that regarding the battery and new roms.
example for Energy ROMs
BATTERY SAVING TIPS
The first few days
• There is nothing special about this ROM to make it use more power than other ROMs except that it is tweaked for performance over battery life. After things have settled down, you should get a couple of days usage out of a charge.
• Immediately after flashing, you will probably observe very poor battery performance. This is due to the charging circuit having to reset itself.
• The battery meter will not settle down and give accurate readings for a few battery cycles. Give it a few days.
• For the first few battery charging cycles, try to charge to 100% with phone off and then allow battery to drain down quite a bit before recharging. This is so the meter will calculate drain well.

Battery drain & other issues
I am not having iszues with 1.48. battery drain.
I heard this so often in the HD forum but never experienced it, and I was flashing Miri's roms every second day.
If people mean their battery runs down very quickly after a flash, well it takes a lot of power to reboot, and then you are probably going to run the device for a while to get all your settings back. Well this I have experienced, but next charge, no problems. I flashed yesterday and recharged overnight and after a day of use my phone had 50% left. No issues yet either.

Was about to agree with you when i noticed something today: i usually charge my phone overnight (it doesn.t matter how much battery i have i just do it to be sure) but few nights i left it without a charge and notice 3% to 4% battery drain overnight (1.43 rom). After update(1.48) i left it overnight and noticed 11-12% battery drain(even though i left my phone for a few days to get used to the new rom). Don.t want to jump to conclusions yet but there could be something about battery drain in the new ROM.
