JasJar crashes at 35% battery power

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.

http://forum.xda-developers.com/viewtopic.php?t=54066
-----------------------------------------------
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

Poor Battery Life with Radio 1.09

I updated my Orange SPVM5000 to the 1.09 radio, and it seems to have had a bad effect on my battery life.
When there is a low signal it seems to drain the battery very fast, dropping 20% in half an hour.
Is this a known side effect of this radio version?
Any ideas on what I could do to improve things - I have searched for battery and 1.09 and trawled through the many posts that are returned to no avail.
I have Orange ROM 1.30.90 WWE, and ExtRom 1.30.174 WWE
(I haven't altered anything else, just the radio, so that seems to be the cause of sudden battery drain)...

I have a grudge as well:
Where there's low reception (or may be - not sure though - I've been using Wi-Fi for a while and then TURNED IT OFF officially) -- the phone gets 100% drained overnight...
During the daytime it's Okay, and the battery loses just a few %, 10-15% during the day... doing Bluetooth ActiveSync and all.
I so far can blame only Wi-Fi, Bluetooth, or Telephone (whatever constitutes "radio").
I think I may look for that elusive application that could help log battery levels, to identify the culprit... I'm really pissed off with this already, and 1.11 reports for the UK aren't very soothing either... Gotta understand why the Hell does it discharge so quickly (XDA II does never discharge that much... and deffo not discharge to 100% ever. But I gave it to my missus now.

Weird... I found my upgrade to 1.09 improved the battery life :? I also turn on flight mode (At the point where I'd turn a normal phone 'off') before i go to sleep - this helps with the battery also

One thing that I am experimenting with is that it seems to happen when I put the device to sleep by closing the lid. If I press the power button first then it seems to behave normally.
This may be a complete red herring, but for the moment my battery life seems stable if I follow that option.

Closing the lid only turns the back-light off - the PDA still stays on... This would explain your lack of battery life. I always hit the power button when I've finished with the PDA

AFAIK the PDA is always on. With the previous ROM closing the lid and pressing the power button were equivalent actions, at least in terms of subsequent battery drain.
It is probably a red herring, and more likely something to do with trying to get a GPRS signal and hold on to it...

The phone is always on - the power button puts the PDA function to sleep however (At least, that's how i understand it)

Battery issue, very Strange

My device : Imate Jas Jar, see below.
My device was doing soft resets when my applications were going in and out of data contection by different software tools, data connection via Wifi or GPRS.
For example I would open Netfront 3.3, then close it and then device would soft reset. I would turn on wifi, then turn it off, the device would soft reset.
Well all I did was change the (orginial) battery over for a new one and all works fine.
All I cant work out is that the power spikes requires to do connection functions must have been to tough for the battery, hence the battery wearing it self out. I have no idea otherwise.
Any ideas...I dont !

i have the same issue now!
do you confirm that changing the battery solves the problem at 100%?
Thanks.
Bye

Yes.. a new battery did fix it.

Is this right, am I reading one of the first battery issues on a Universal running WM5 as opposed to the other battery issues under WM6?

other strange issue from me :0)
After changing to WM6 my Device( Universal) use to shut down ca. by 30-35% remaining battery reading. After following so many post here I thought my battery is going down.
However just recently for few days I have flash back the original ROM. Now comes the strange issue: After flashing the original ROM I have observed that I could use my device (with same battery) down to 5% reading.
After one week later flash back the WM6 and see there the device shutting down again by 30-35% battery reading.

I have always and still do suspected a falwed battery interface driver in WM6 but could not technically reproduce it. This is still a work in progress for me but its good to know that there might be a real problem after all in WM6.

Battery dies in less than 24 hours.

Hi guys.
My wizard battery lasts less than a day. I hardly use it. Wifi and other radio are off most of the time.
I tried changing ROMs, radio roms etc. I even got a new battery but to no effect.
Any help ?

I had that problem until I found out that activesync was staying active even after I unplugged the cable. I never found a way to keep it from doing that though so now I just make sure activesync is shut off wheneve I disconnect it. Kind of a pain, but it beats the battery dying on me.

Well ill make sure Activesync is off.
But do you think the problem would persist even after I changed roms!

It did on mine. It's something to do with activesync itself apparently. It doesn't stay on as often as it did when I was using T-mobiles ROM, but it still does it occasionally.

make sure your extrom is ok, because a corrupt extrom is also a cause of battery drainage, better yet there was a rom floating that only erases your extrom (blankextrom), i forgot who made it but its from the wizard forums

found it, go to post number 7, look at the sig below there is a link for the blank ext rom, enjoy

Maybe your battery is bad. Buy a new one on Ebay for small cost. I bought mine for like 7 euro`s including shipping (battery itself was € 3,5). Also disable mail fetching every few minutes.

i tried two different NEW batteries straight from tmobile and the problem persists. and mail checking is on manual, which means only when I click send/receive

I'm pretty sure mine was caused by activesync running even though it wasn't connected because ever since I started making sure it wasn't running after disconnecting it from the cable my phone hasn't had that problem at all.

i end-tasked (closed) activesync from running in my phone when i went to sleep, and when i woke up i lost 50% battery again, (with all radios off)

Some programs can drain the battery. As an example, I really like PhoneAlarm, but it drains the battery tremendously, I think it's because it polls different system parameters. This polling causes the battery drainage.
Also, the way to stop activesync from turning on by itself it to create an exchange server account. I use mail2web, it’s free. After you set up the account on the phone, when you go to the activesync menu, hit schedule, then set it up for manual.
After I set this up, I never have a problem with activesync. You can do a Google search to get the step-by-step directions on how to set it up.
Also, charge the battery with the wall power cord, try not to use the USB power. Each one uses different circuits in the wizard. I also let the battery drop below 10% before I charge it. My battery lasts about 4 days.

Like calouro said, there are other programs that can drain a battery pretty quick, mine happened to be activesync. Since you shut it off and you still get battery drain then yours must be a different one, possibly a today plugin if you didn't have any other apps running in the background.
Just had a thought, you don't have any today plugins such as weather panel that are set up to update over gprs on a regular basis do you? If you're turning your radio off and it can't update it may be trying over and over to update and draining your battery.

no i don't have any today-addon or plugins, i have batterystatus installed but this problem persists even without batterystatus and it does this even after a fresh HARD reset, which tells me this is a manufacturer's program or hardware causing this flaw, i'm not the only one with this problem, there are others, look at our discussions here: http://forum.xda-developers.com/showthread.php?t=319897

Yah, I read that post. Did you try not turning off the radio over night and see if that sloved the issue?

I've changed batteries. Using a brand new one now.
No active today plugins or anything else. Dont even have activesync running. Made sure I exited that. Still no help!

how did you flash?
i think it may be extrom prob, as someone said earlier. if you are flashing with shelltool, extrom(corrupted or not) is not replaced, when its broken, shelltool rom change will not help.
second thing is "fake connection" for activesync to stop it from turning on and on in searching of sync.
third thing is using soft, that is waking up/keeps machine awaken somehow...
xeno1 said it all before...
i think it may be something installed from good extrom too(extrom holds programs which are installed after first boot)....
one more thing:
after >60 flashes i noticed, that level of battery while flashing may be reason of fast nrg loss.
If it was 50%, machine(even charged to the max after flash) drops fast to 50% then drop slows down - wise thing is to let it discharge to ~5-9%, then charge to the max. After 1-2 such operations battery is ok.
It is useful, even if battery was full(machine "learns" about battery as it is new - sth like that).
there are no miracles.
sorry for funny english..

HEre's something funny that happened.
Before flashin a blank extended rom I had 73% battery. Once the flash was over I had 100% battery.
Now I'm tryin to drain the battery with backlight and phone and wifi continously on. Once that is done, I hope things will get better. I'll keep posted with what happens.

Even after a full recharge, the battery now doesnt last even 12 hours. And this is me not using the phone at all. It's just been switched on and kept that way.
And no thebacklight doesnt stay on, or the phone doesnt stay on (it goes into the standby mode as it should)

yea if i don't turn off the cellular radio then the battery only loses about 1-2% overnight (9 hour sleep).

Battery issue

I have read some threads about htc devices and their battery- life and behaviour and i didn't really read about the problem i'm having.
The device (topaz) is about 2 weeks old and i'm fairly satisfied with the batteryperformance. Playing with it for about ten minutes would make my battery drop about 5% which is very reasonable.
But lately - speaking of 3 days - i have this weird issue; the battery drains like hell; when i send 1 text message the device can drop 5-6%; which is quite much and absolutely a heavy fall suddenly, compared to what it used to be.
Also, when charging the battery, from 0-70% goes very fast, like about 10 minutes. The other 30% go slow.
I configure the device like this:
- GSM mode
- No wifi
- No bluetooth
- no data connection
System: beam is switched off, data only goes through 'my work network' and band is switched to GSM (which means no 3G - again)
My experience happens when i have no other applications (like GPS) running, and I also have G-light enabled (polling 100ms, mostly 40% backlight, and i have this running since day 1)
I did switch my rom quite often; but I always performed hard-reset and battery calibration afterwards.
installed in current order:
- Touch InCall
- Tomtom navigator
- ageye g-light
- TD2 tools (large cache settings)
- Taskbaricon 6.5.3
- Zenyee disable HTC messaging
Roms used: Dutty R6-R7
Radio: 4.49.25.17, 4.49.25.57

There are some rather aggressively power hungry ROMs and the culprit is mainly Touch flow/HTC sense.
Turn it off for a test and see if there is a difference!

Well, I do experience similar problem. My battery charges for 70% very fast and at 70% it seems to stay forever. (whole night) I haven't done anything to my phone yet. I have it just like it came from T-Mobile. I didn't install any additional application besides sbp backup. I do keep my memory running at around 40% all the time. I have Win6.1 and TF3D on. TF3D is T-Mobile customed, so not sure what manila it is based on.
Please, anybody, do you have other suggestion as what the problem may be?
I want to flash the ROM, yet with these issues I am still reconsidering. If it is faulty battery I would rather go and exchange it as it is still in warranty.
Thanks in advance for your help.

does anyone know a link to how to keep the battery in tip-top shape. I know there is a post somewhere on xda, but really don't want to look over about 1300 posts to find that. Can someone help me?

"Battery calibration is simply done by running it down completely until the phone shuts off by itself. Then remove the battery, wait 10 seconds, insert again, repeat. If the phone shuts off again in less than a few minutes you're done. Remove battery and hold power button for 1 minute, then insert battery. Don't switch on the phone. Plug the charger and recharge the battery fully until the green light is on. Then remove battery, hold power button for few seconds, insert it and switch on the phone..."

thanks for the tip. will try that. Still, a link for battery tips? I remember a post where a member explained how the battery works I am interested in knowing if it is better to drain the battery or when the battery is lo/very low it would be advised to recharge ...

Here is a link on the Wiki regarding battery consumption.
With Li-Ion batteries it is not recommended to discharge completely as it is with NiCad every 30 cycles.
If you have flashed another ROM that has changed your radio ROM, i.e. you've flashed an official ROM, the Radio ROM will be your culprit for increased battery drain. A weaker radio will constantly have to search for the best network and thus use more battery.
For a few power saving tips;
1. Setup sync times instead of pushing emails.
2. Make sure your data disconnects after use (a few programs out there for that)
3. Set your power settings to turn device off at select times of inactivity
4. Increase your file cache size.
5. Enable auto screen lock

how do you enable auto screen lock? I'd rather not use TD2 Tools. is there any other way?
