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.
Well judging by the number of threads on the subject this problem is very widespread, check out the threads below:-

-----------------------------------------------
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

Hi!
I'm using the latest QTEK ROM with A2DP.
The problem is that my set blacks out at 38% battery power and refuses to power up after that unless I re-connect to the AC for charging. It happens a couple of times already. Any setting(s) in the Universal to check this?
I remember I managed to get the battery level at real low level (less than 5%) previously prior to the ROM upgrade.
Thanks
Hi,
I have a similar problem.
I charged the unit till 100% then reflush the Rom

RE
Hi JoseF
Thanks, however, I'll consider this as my last option
Meanwhile I would like to get more feedback on this issue
Qtek 13077 ROM ????
My i-mate continues to crashes with the battery is less then 43%, apparently the problem occurred when I made 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 miter showed 23%, then I made a phone call, the i-mate crashes in seconds. Could somebody inform what is the true voltage of the battery in the i-mate is 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 for Qtek, we needs to investigate what the the Qtek ROM this doing with the JasJar?
Ive 3 batteries
The standard 1620mah dynapack which works fine 100% to flat no worries
A 3200mah extended which will charge to full but dies at 43%
(the guy replaced it with another which did the same thing)
and
A 3000mah which will go flat ok but wont charge beyond 47% and the orange light stays on forever, although luckily it doesnt fry.
has anyone had any of these extended batterys work ok?
Just to add a bit of info, all modern li-ion have a built in fuel guage chip which tells the device its in how much power is left in the cell. so its possable this is a battery issue rather than phone problem
r 1.03.00
g 42.36.p8
d 1.30.90.wwe
RE
You may be right about the battery thing
However, I've tested my existing battery to very low level prior to the ROM update without problem
And with other feedbacks in this forum I doubt it could be a coincidence that our batteries are having the same issue.
I would rather think its a ROM thing.
I'll need to test my battery on another Universal before confirming.
I just tried to flash to an older rom but got a country error, there seems to be no old orange uk rom i can find.
Im a bit new to all this rom flashing business and also wanted to try an older rom to check out the camera as im not sure if i have a realy poor camera or if there is a software issue with that in the new orange rom also as one guy in another post is getting far better results out of his camera mines like a real snow storm in the dark parts of pictures
RE
Yes, the new QTEK ROM update does cause the camera quality to suffer especially when in night mode
Well, just have to wait for another ROM update to resolve these issues :roll:
Fosa or Zarn
You have a digital multimeter?
Case yes: You it could measure the voltage of the battery when is total loaded 100% led=green, and when the battery will be flat 0%. This test would be excellent to verify if the Battery power remaining is correct. Currently when my battery is with 3.28V = 55% in the battery power remaining = crashes.
ok, can do, not that it will help much unloaded.
I'll charge the original cell and post the results shortly.
The battery management wont always turn the battery off at the same point as the battery ages it will change. You have to bare in mind that a battery is a little like a piece of rubber the harder you push on it the bigger the dent but when you stop pushing it recovers its shape.
The same goes for the voltage of a battery, when you draw a large current the voltage will drop further than if the device is in standby but once you disconnect the load there will be an amount of recovery
li-ion batterys are far more complicated than they first appear.
The battery is by no means connected directly to the phone.
there is a microprocessor in the battery that controls both charge and discharge via 2 fet transistors, buy doing this it protects you against the battery exploding/catching fire from over charging or over discharging.
As far as im awaire the microprocessor will adjust both switch on and switch off from many variables not just voltage drop.
The phone its self mearly supplies power to the charger built into the battery and draws power from the battery all the measurement and battery managment is within the battery
This is why the battery suddenly just stops and you need power to bring it back to life.
so in theory no matter what the condition of the battery it should always give a full scale deflection from full to empty as the onboard management should know how much capacity is left in the cell and report this via the data lines to the phone
If you connect a bulb to an almost flat li-ion battery you will find little drop in brightness before the battery just cuts power totaly to protect the cell within from over discharge.
Something that springs to mind that hasnt been mentioned here is have you checked all 4 battery contacts are clean? just a thought because the two larger outer pads provide power while one or both of the smaller pads send data on the charge status to the phone.
heres some interesting reading
http://www.batteryuniversity.com/parttwo-34.htm
Intresting reading on the care of li-ion as they dont like being either fully charged or fully discharged..strange eh...
http://www.maxim-ic.com/appnotes.cfm/appnote_number/128
http://www.intersil.com/data/an/AN1174.pdf
two examples of li-ion battery management.
safety law dictates any li-ion that is user replaceable must have one of these little chaps built in.
hope that makes sence

RE
Sorry zarn, but I don't have a digital multimeter.
Is your test going to prove that the battery is going to its end of life soon?
How could that be since the Universal is less than a year old? :roll:
At any rate I'll be testing my battery on another Universal without the QTEK ROM update to determine whether its a battery issue or the ROM update issue.
Im just going to do it out of interest... like i said in the previous post its not likely to prove anything except if the guys battery is totaly out of whack
Dear Fosa and Zarn,
I’ve already known those URLs:
http://www.batteryuniversity.com/parttwo-34.htm
http://www.maxim-ic.com/appnotes.cfm/appnote_number/128
I liked very much this article:
http://www.maxim-ic.com/appnotes.cfm/appnote_number/128
However, when I asked to verify the voltage of the battery and without taking it off the charger, I’ve put two tiny wires on the terminal of the battery, in the manner I could verify the voltage without taking it off from the Jasjar. Last night I’ve left it charging until the green-led light and I’ve noticed that the voltage was 4,231V = to 100% on the battery power remaining miter.
I’ve did a test putting the light of 4V to discharge the battery, and at the 2,83V, it disconnected automatically (stopped to supply current). In more or less one minute, it starts to provide energy again, in other words, the protection circuit of the battery is Ok, and is not with this tension (2,83v) that the Jasjar stops, and only when is 3,28v.
I’ve got the feeling that the problem is on the ROM, however I did reinstall the original ROM and yet the Jasjar still crashes at 58% of the battery(= 3,28v).
Before making the upgrade the miter was going from 100% to 5% without crashing.
With the ROM Qtek WWE_13077_130176_10900 the miter shows 100% to 42%, and at this point it starts to crash.
I’ve already bought a new battery just to test it, but it still not arrived from Hong Kong, and as the customs is on strike here in Rio de Janeiro, Brazil, I don’t know when I’ll get it.
Until now I think the problem is that the Qtek ROM made some changes on the firmware or in the register of the battery, changing the miter calibration.
Battery results
Im suprised it cut of that low, thats very low for a 3.7v li-ion, thats more what you would expect from a 3.2v.
Anyways, as requested heres the resuts of checking the voltage at various points.
This is using an original dynapack 1620mah battery as supplied by orange with the phone, but its around 3 or 4 months old now so far from fresh.
the meter used was a Avo M801 (not a cheap one though is probably due to be calibrated...)
100%----4.16v straight off charge still warm
75%-----3.93v
50%-----3.78v
38%-----3.76v
25%-----3.73v
10%-----3.65v
5%------3.63v
cutoff----3.58v
Im going to do the same with the extended batterys im having problems with just as a comparison, will post the results here if anyone is interested
Whats going off here...?
I just put one of the extended batterys in which was fully charged..
to be greated with a blank batery bar, and unknown in the chargeing remaining window... unpluged and repluged the charger and was then told battery at 225%
doh.....
Jasjar battery miter
Hi Zarn
Thanks a lot for the table of % * V, now I am certain convinced that the Jasjar miter needs to be calibrated again, I believe that the problem is the DLL or the responsible register for this detail(miter)?
While I or somebody of the forum does not find the solution, I will continue using this way, because the battery still lasts for 24h.
RE
OK guys, bad news
I used my battery which knocks out at 43% from my QTEK 9000 set and put it into another QTEK 9000 set without ROM update and it also fails to boot up unless I connect it to an external power
I hope that QTEK can release a small ROM update to resolve this issue
so hang on..
you put your battery into another non updated rom handset and it still wasnt working properly...
surely that means your battery is at fault not the rom..
cant u borrow the other guys battery for a few hours?
Are these original batterys were talking about btw (1620mah dynapacks)?
or cheap replacements?
RE
Hi zarn,
My battery is the original default battery....the Universal is less than a year old
Could it be that the new ROM update has changed something in the battery...maybe the IC chip in the battery, if any?
RE
zarn,
If you'll read another similar thread you'll find many others with different variants of the Universal facing the same problem after upgrading the new QTEK ROM update with A2DP
Are you saying their batteries are faulty too...such a coincidence?
Hi I was in Hong Kong and I bought the O2 XDA NEo the problem is that everytime I hit around 45% the shuts off, if I try to turn it on it will go to the windows splash screen and go into a restart loop but if I charge my phone it won't happen. Is something wrong with the phone or the battery is diffective?
How long does your phone last on a battery? And what are you using with that (e.g. when you always have bluetooth and wifi enabled the battery won't last as long as when you don't have those enabled).
Because it could be your battery is faulty, or the chip on the battery is faulty (from which the % is read).
If your phone, fully charged, lasts for a few days (3,4,5 depending on what you do) it doesn't seem the battery would be faulty but the readout is not that good.
Have read things before about phones shutting down when it says there is still 20% battery left or something which might just be a mis-reading. When I use the battery of my old magician the readout seems to be fine although when I use the battery that came with the prophet I saw it shutdown once at 10% (though I never make that, because it's always charged before that point ).
its actually gotten worst now it will shut down at around 60% and will go into a restart loop if I try turning it on
hmm, something is not right (doh). I recommend you bring the device back for servicing.
However, if you have a battery laying around from a magician or another prophet try it with that one and see what happens. At least you can rule out the battery/device. But otherwise you can leave the tech-guys to that
I did order a new battery from ebay but its not here yet so I can't rule it out and as for repair it will be kind of hard since I bought it in Hong Kong while on a vacation and now I'm back to canada.
so I finally got the battery from ebay the 45% shut off problem is gone but now I have new problems, I notice with this battery the neo runs slower which dont' make sense and for some reason it won't charge when the neo is off only when on, also it won't charge pass 89% so the light on top is never green??. The first thing I did when I got this battery is fully discharge it until the phone shut off and recharged it while its on because it won't charge when it's off? any ideas or did I get another defective battery??
Hmm.. that's weird. Did you upgrade it with another rom perhaps (e.g. AKU 3.2 or something). Because those roms sometimes have troubles with charging.
But the phone should be charging allright when you turn it off (well, make it go in standby that is). Or do you completely turn the device off?
Can't imagine you have 2 faulty batteries though :/ Maybe there is something wrong with the device? Hard to tell...
completely turned off and I'm using 2.3 rom LvsW_Edition
great I tried flashing to the dopod rom got an error and stuck at the 3 colour screen i think its the bootloader what do i do now?
erm... well you could try the 2.20 qtek rom which seems to be working well for quite some people (found here).
Although you have to make sure you read that thread good and use the ROMUpdateUtility_NoID.exe (found on ftp) to upgrade (or you download RUU-Prophet-G4-AKU2.2-2.20-2.47.21-Jester-r1.exe and take the ROMUpdateUtility_NoID.exe from that using WinRAR, but it's wasting bandwidth a bit ).
Update instructions:
1: With the qtek 2.20 rom you need to extract the zip and the exe file in the zip with WinRAR.
2: Then there is one folder called 'OutputFile' and a folder called 'RUU_TOOLS'.
Inside the RUU_TOOLS there are some other folder (prophet -> WWE), when you go through them and in the WWE folder you see a bunch of files (readme.doc, enterbootloader.exe etc etc).
You need to copy ROMUpdateUtility_NoID.exe to the WWE folder with all the files. And you also need to copy the 'nk.nbf' file to the WWE folder (from the 'OutputFile' folder).
3: And then you need to put your phone in bootloader mode and run ROMUpdateUtility_NoID.exe to upgrade, which should work nicely then.
Hope that was a good and clear explaination
I just reflashed the rom with LvsW_Edition and it brought my phone back to life but I still have the 89% problem but thanks for your help anyways
Well, I have no idea what could be wrong.
My phone charges when it's turned off, so I guess it must be a phone problem :/ Maybe a charger problem, but that seems unlikely.
well I don't know what happened I guess after the 2nd discharge the phone is stuck at 98% charge now not 89% I dont' think it's the phone or the charger since the old battery that dies at 50% charges with the phone on or off, I'll keep discharging this battery maybe it will eventually bring it to 100% full charge
I had enough with this battery its completely unusable with this battery in my phone it slows down so much that navigation is impossible, I have to reset the damn thing every time. I was reading on a post here regarding a 1800mah capacity battery for the prophet so I bought that on eBay and sending this garbage back.
The scenario is this. I charge it every night. The orange light does work and it will show 100% in the morning. It will then shut down at random times and when restarted say the battery is low. I can plug it in again and reset it and it will show from 0 to 100%. Once I take it off the charger it may run all day and deplete the battery or it may die suddenly and tell me it's got a low battery again.
Should I consider the phone dead or does it sound like a faulty battery. It is the original battery and is 2 years old.
Marksm,
I think could be caused by:
1st: some hidden app wich consume a lot of energy that is placed on your phone or
2nd: a phone virus made to produce that behavior or
3rd:a battery control software issue.
For that, I'd advise you to:
1st: verify the programs and process that are running on your phone, seacrh for unknow ones and see on the internet what they do so you can remove the unwanted ones;
2nd: install one or more of the mobile antiviruses (one at each time) that are avaliabe on the internet and perform a full verification of your PDA;
3st: put a new ROM on the Blackstone; but first read how to do it well, if you don't know how, and be sure to be aware about all issues and risks that this action may bring.
Wishing you a good luck!
Stay in peace!

I have exactly the same problem. I restored the original ROM and SPL and nothing has changed.have you tried another battery? Is like the battery controller is broke. The phone is under warranty but the battery is not covered, so I would know if send it to HTC or to buy a new battery!
Similar issues reported in a post above. A new battery seems to have fixed it but needs more time to tell. I will probably order a new battery too.

turn off your phone, plug it all night long then restart in cwm recovery and do "wipe battery stats" ( or something like that in advanced)
restart and see
I have already tried that i have turned the phone off and left it to charge for two and a half days long without disconnecting the charger but the light still didn't turn green.This is really annoying cause the battery drains fast and when its less than 15% the orange light turns on which i don't like to see
I have the same problem with my Legend since I update from stock 2.1 to 2.2.Actualy because of this I root my Legend then i can calibrate it but nothink seams to help.After all night charging the led is still red and when i start it up it shows 75% and go down fast.(1 hour or so can bring it to 5% easily).After when i switch it off and take out battery for few second and put it back it come back to about 55%.actualy the same problem as you have.
I just live with it....i trayed every calibration method and app. and nothink helps.
On another forum one guy told me then it probably need to be recalibrated in factory because i dont have the right tools for it.
I dont think then HTC will do that for me specialy after i root it.
If you find solution please let as know.thanks

Then unroot it, install your carrier's firmware just the way it came with on the phone, and send it back. I would imagine it be hard for them to tell that you've rooted it.
Or just before you do so, check if the battery's still messing around before you send it back.
I have two battery's and the problem is the same with both of them.If is true then they can not understand i will give a tray...i think then this is the first think they will look it at just to tell me f**k you..hahaha
I' ve the same problem with stock legend 2.2. How can we do?help!
Inviato dal mio HTC Legend usando Tapatalk
So this is what i tried i drained my battery completely till i had 1% of charge then i put it to charge while the phone was still on and it has been on charge for two days and i see that the phone has charged to 76% usually it would charge to 65% so maybe if i leave it for a couple of days on charge i could get a full 100% charge.So that is my last hope unless you guys find something else.
I will post back if it works for me
BTW couldn't it be a kernel problem??
All I know then the problem started when I update from 2.1 to 2.2 stock rom.so my theory is then when you flash new rom the process take some time and energy from battery and when the process is finish the system take current battery state as full which is not true because of used energy from flashing process.So maybe providing DC power with the same voltage as fully charged battery when flashing new rom may fix it.I maybe wrong but in theory it may work.what you think?
I have 2.2 since release date,and the problem is present since one month,after about 6 months 'hotspot mode' for home internet.i think is a battery problem (charge and navigate at same time for 2 hours for day)but this thread show that is a common problem!
Inviato dal mio HTC Legend usando Tapatalk
i'm having the same kind of trouble for the past 2 months. no matter what i've tried nothing happenned. i'm running custom 2.2 , without rooting or so and charging level stops at 71-75%. drops down relatively quickly until 15% and easily can stay with 3% for over than 5 hours.... htc suggested to run a factory reset,but even this didn't help. if someone finds a solution it would be ...LEGEND...
The phone is actualy charging the battery correctly,i find that out with the multimeter.I measure the battery voltage after all night charge and even then in the phone it shows 75% and voltage 3.950 with multimether i find out then voltage of the battery is 4.220.So thats mean then phone is charging correctly just the indicator(software)doez not interpret it it right.Still is anoying to look at red led after 1-2hours of use.
I have S-ON so maybe even if the calibration app.say after i tray to calibrating then batterystats.bin is deleted it maybe not true becouse of S-ON.
Do you guys with this problem have S-OFF or S-ON?
Maybe is not related to S-OFF or S-ON but who knows...
Maybe if we charge the battery till its full and testing it like pirate81 said with a multimeter and then flash a new rom maybe that could fix it has anyone tried this??
I start to think then XDA developers forum is useless...i post my problem hier to get help from people(xda developers)which I think then they actualy know somethink about android but It seams to me then XDAdevelpers actualy dont care..end i am sorry for that....dissapointed.I see then this forum works on basic.."help your self"...where are you XDAdevelopers...we come to your forum because we need help from you...
I know you doing it for free so i should be happy for what i get but i was waiting a little bit more of interest....sorry i am just dissapointed.
Anyone find a solution?
Would it help if we went back to android 2.1
I allready trayed that..save your time...no changes.
Can't we just use someone elses battery stats file someone who's battery does charge to 100%
I have same problem for 6 months already and yes, it started when I upgraded from 2.1 to 2.2 and it's only getting worse. It was 95% maximum, then 75% then 65% and now it's 45%.
Changing battery or firmware (custom or official), wiping stats, factory resets or calibrating batteries does not help.
Now it dawned on me that I still heve 2 weeks of warranty left and I think I'll try official service.
Please let as know when you will get it back...if they change just rom and calibrating or you will get new phone.I am interestig if it is software or hardware issue.thanks
