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

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 have brought a new battery it is a high power version 3200ma and when it is in the pda it allways reads 100 % on the battery meter does not go up or down so dont really know if its charged charging or empty any ideas.
the same here
no ideas
No solutions yet
my 3800mAh from expansys operates correctly with the battery meter.
Same problem, its not a bad battery meter, its a ****ty third party battery. E-bay, right? i bought two of them from different people, and my batteries kept playing up for no reason. I marked one to keep track of which one was which and it turns out each have different problems. One stays at 100% for ages, then drops gradually to 78%, gives me all the error messages, and after a soft reset lasts till ~50%, and the other has different issues. It must be something to do with the chip on the battery. There isn't really a solution in my mind, just make sure you know what each battery does
ahh i should have read this earlier .did any one bought battery from mr buybits off ebay? if so do's it has any problems ?
My hermes standby time was about 2-3 days depending on my usage. but two days ago, i charged my hermes to %100 and then i slept, when i woke up in the morning, my tytn was closed, i tried to open, but it did not.. So when i pluged the charger, red light flashed and then yellow, which means my battery was fully empty and started to be charged, so it worked again.
And now it takes about 2 hours to be fully charged, but it only takes 4 hours to be completely discharged again!!! It happened so suddenly! As i know, batteries die slowly, not that much suddenly??! Do you think there could be another problem?? Or is it just my battery?? is it possible that my battery died in one night??!
I could think of a couple of things...bad battery, faulty device, or you are just doing so much with the phone that the battery is being drained. Do you keep bluetooth turned on, and wifi, and have your phone polling for new emails every 15 minutes? That will most certainly drain the battery really quick. Also, do you have the device set to automatically hibernate when not in use? I just received a new 8525 due to warranty 4 days ago, and I have not done any modding to it yet. Off the bat, I noticed that my battery life has significantly increased.

There are causes depending on the battery and causes depending on the hermes:
Battery:
1> The battery has a certain lenght of life. This type of battery is very sensitive and can be charged around 300 and 500 times. Each time you connect the charger you "consume" a bit of the life. Nothing to do with memory effect but with the physic of lipo batteries. How old is your battery?
2> Lipo batteries can not be discharged below a certain voltage (3.00 volt per cell. The hermes battery is a one cell type). If this happens, you kill the battery (short capacity, impossible to charge,...) The pda is normally equiped with a circuitry able to avoid this.
PDA:
1> You can have running applications burning power. But you know that
2> In certain circumstances, the motherboard can have a problem and starts to burn your battery. This is a hardware problem which needs MB replacement. This problem is described in the maintenance manual of the hermes and is tested by service people when a hermes is refurbished.
You can try the following:
1> Fully load your battery and close all applications (No phone,nothing). See what happens in one night
2> Fully load the battery and shut the pda down. See if the battery remains fully loaded. If it is not the case, try again with the battery out of the phone. If the battery is partially/totally discharged with the battery out of the pda, the battery is dead.
3> See how much your phone consumes by using this application: http://www.acbpocketsoft.com/Products/acbPowerMeter/acbPowerMeter-Overview-2.html
Start your hermes without anything loaded (no phone,...) With backlight on (default level) and nothing running except this application, the level will be around 70mA (average). Without backlight, you would be around 25mA. At least this is what i get on mine (rom,... see my signature). This test is very dependent of the OS and the radio rom loaded
This will not repair your battery, but i hope this will help you to identify the problem
" As i know, batteries die slowly, not that much suddenly??!"
yes like humans batteries age and die after awhile
but all electronics like humans can die of a "heart attack" too
Thank you everyone is very helpful here Well i found the reason for my short stanby time, i am using pays rom 1.31 and there is a program called HSDPA switch, somehow when i uncheck the `Turn on HSDPA` box, everything seems to be normal again!! After a deep searching week, now i know the problem. I know its very odd, but when i re select that box, again my battery finishes in about 2 hours... Strange yep..
I know there are already a lot of discussions on battery drain and believe me, I have read every single one of them. However, I think mine is slightly different:
When fully charged and using WIFI for 10 minutes, 10% of juice will be used. Listening to MP3 for 1 hour will also use another 10%. Overall, battery life is really bad but the key is it only happened suddenly. It have been very good up till now.
I have tested this on another battery and have exactly the same results so it is not battery related. I have also hard reset the phone and tested the battery with nothing installed and it still drains. A full charge only lasts me like 4 hour of very light use.
I installed Battlog and the power consumption is around 90 which I think is pretty low, but at times, even with this low consumption, I can see the battery usage literally falling before my eyes, like 5 % in 5 minutes.
I have also tried the HTC battery test, i.e. fully charged the battery, turned on plane mode and full brightness. After one hour, it only used 8% which I thought is normal. However, if I start using the phone by just simply clicking around, it will start dropping.
I believe the phone is fine on standby but once it starts doing things, even simple operations like moving around folders, it starts consuming a lot of power.
This all happens after an overnight charging episode when I noticed that the light stays amber in the morning and the percentage stays at 80%. I soft reset the phone and it immediately show 100%. This has never happen again but my battery usage is never normal since.
All in all, I think it is somehow hardware related, like the battery gauge is bad or the charging is never complete but it still shows green. It is still under warranty but I think will be very difficult to convince the service centre that there is something genuinely wrong with the phone.
P.S. Should also mentioned that I am using the stock telstra rom and have also cycled through the batteries twice before testing.
I had the same problem...
You should try resetting you battery:
1: let your battery drain to 0%
2: fully charge your battery while keeping your phone off!
this solved the problem for me..

I had actually "reset" the battery but only drain it to 5% before recharging as I have read that it is not safe to drain to 0%. I'll try to completely drain it tonight and recharge. Will report back.
btw, I noticed that when the battery is charged to 100%, the led stays amber for about 15-20 minutes before turning green. Is this normal or should it turn green immediately after reaching 100%?
Tried completely draining the battery and charge overnight but have no effect. The problem persists. So this is definitely not a battery problem.
I guess the last thing I can try is charging the battery with a standalone charger or another HD to see if there is problem with the charging mechanism in my phone.
The latest Telstra rom seems a bit better on battery
led amber
The led amber must turn to green
immediately after unplugging.
some thing is wrong with your charge

aidinali, can you please explain what you mean? I thought the led will go off if you unplugged the charger. My problem is that after reaching 100% as indicated on the phone, the led stays amber for another 15 minutes before turning green.
Well , I'll correct & explain more....
1-when you reach %100 ,the led will turn to green immediately (if you’r phone is plugged in).
2-if you unplug ,the led will turn off (as you said ).
The problem is that since the battery meter in HD has not been defined by percentage , it doesn't match with
Apps like battery level or battlog .so when you see %100 on them , it' s not "real % 100 ".
I believe there is something wrong with the phone as the percentage usage and charging status do not match. However, since the basic HTC software does not have any battery usage in percentage, it’s hard to convince the service centre that something is wrong.
Any software that shows the battery as a percentage all have the same reading, so I assume they all rely on the mainboard for that information. There is obviously something wrong with either the charging process of the phone or draining more battery than it needs during usage.
I have 100% exactly the same problem as in the original post.
Does anyone else?
I have also tried 2 batteries and had exactly the same results with both, so I also know it is not the battery. The only app I have installed other than Dutty's 6.5 rom is Tomtom which does not need to be run for any of these issues to occur.
Any chance on warranty? I think it's software...
Try a different ROM. I've been having the same problem. I just flashed a new ROM about an hour ago (partly because Dutty's 6.5 kept freezing). I'm hoping both problems will be solved now.
i've found the latest radio rom to make a big different to battery life. 1.14.25.24_radio
the previous radio rom (1.13?) did suck the juice and made battery last 2 days less than 1.14
Try charging with a different charger. Ie. connect a USB cable on your PC and charge it from there.
I've had very similar problems with the stock charger a month after i got my TouchHD, and ended up testing with my old P4350 charger and all problems went away.
I've had similar drains even witch WiFi off, no emails, exchange or 3G access...
Now i'm getting a whole day's usage and i'm left with 30-40% battery, with 2 hours average talk time
I've tried with a number of chargers.....battery still sucks.
I've just switched from Dutty's to Energy ROM, radio is 1.14
If anything...energy drains more quickly than Dutty's
It says it drawing 350mA
Ok, I've used Energy ROM but now using Dutty's Leo. The only thing I've loaded so far is Battery Guard which say it's drawing 98mA when on standby(ie....backlight goes off). That'sa massive difference on the 250mA readings I used to get....now all I have todo is figure out which program I'm loading that is killing my battery.
That still only equates to 12 - 13 hours on a good standard battery with no use at all.

Standard battery should last longer. Sounds like your battery may be slightly faulty. Make sure you let battery drain fully before charging, and always try charging with device off. Should help improve strength.
I had same problem when i flashed miri's rom, hd got warm and didn't last, it cooled down in standby, the answer to my problem was that the wifi was not set to save battery mode, once i set it to save power everything was ok
Used 8% in 24 hours

Have been trying that for a month now....something seems to have suddenly worked It only used 8% of the battery in 24 hours! I live in the rainforest with no service so cellular was turned off...wifi on, but I only accessed it about 6 times......still,nothing has changed. The same conditions would leave me with a dead battery in 7 hours previously.
Time will tell if it keeps up this well.
By the way....Thanks
So basically you're saying people should drain down the battery to 1% or so and not to 0% (device dies when battery is out) to get a better battery strength?
Seems to be the general consensus. I'm still not sure if that's what made the difference for me but previously,I would put my device to standbye when I went to sleep at 10:30pm and it would be dead by 6am
Hello,
Sir like many others, I too have a battery problem with my SPV M3100
The battery always shows it's status in the 10s. Which means like..
90%, 80%, 70%, ...
It never shows up something else then tens which is not really good.
The second problem. If the battery is 100% charged, I open WIFI in few seconds it will drain to 90% and 80% and then 70%.. It drains really very fast. I know that WIFI eats up the battery but not like 10% in 1 minute???
Third problem, If I keep my mobile 100% battery on stand by mode and I don't get a call. After 24 hours I go and see it will show and battery left 100%. But if I go and do a small task in mobile, it will drain like 30% in once. That is quite ammazing I have never played on music so can't say how much it drains while playing music on hands free.
Overall on standby mode, the battery lasts like 3 to 4 days. But if you use it for even a small thing, it drains really fast and battery was dead.
Please help, I think this all is not normal, Radio version can be the reason of this???
Thank you very much
Faisal
i have too this problem, if you find any way for solve this plz help me
I have the same problem..
Even when I go online with GPRS/3G/UMTS/HSDPA..
Does the problem come from the battery?
My battery has UTSTARCOM text on the battery. How about you?
EDIT : You need to flash a ROM with a 1% increment fix, it's because the stock/official ROM has 10% increment battery meter, I don't know why.. And my battery drains very fast because I have over-charging it.. I leave my Hermes charging overnight when I'm sleeping, and it leads to over-charging.. You need to unplug the charging cable when the charging complete ASAP..
I have the same problem on my Spv m3100. The power meter deplete at 10% increments. Unlike my HTC TyTyn 2 - Kaiser this shows actual units.
