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?
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.
Hey guys,
First of, YES I USED THE SEARCH FUNCTION .
My battery life is absolute horrid right now, and I tried everything.
I tried out different roms, every radio, deleting programs, hard resetting tons of times. I even bought a new 1500 mAh battery but it was still crap.
Battery log says my device in standby mode with the screen turned of uses -70ma, when I turn my screen up it jumps to -320ma, and when idle on the screen for a few sec it goes to -200 ma, but when I browse through stuff again it goes to 3xxma again. When I surf on the internet it picks up to 450-500ma.
Now, this morning with the 1500 mAh battery fully charged I played a few games of XTRAKT, few texts, 1 hour of music listening and 10 minutes of being on Opera through a HSDPA connection. It was down to 45%.
This isn't the normal rate the battery goes down at right?
I use HDtweak to manage my connection and put it off after a minute so it isn't that I keep dataconnections open. I never use bluetooth or wifi either.
Could it possibly be that it's the charger of the device? I perhaps have the feeling that it doesn't put enough juice into the battery even though the green light led goes on to indicate it's full.
Some feedback would be much appreciated cause it's put me on the edge of selling my device, which would be a shame cause I'm really fond of it (except the battery ofcourse ).
Thanks in advance!
/a
P.s. I am from a pda background, so it isn't that I'm expecting too much of the device or comparing it to a normal cell.
May I ask what you searched, as there are 3 or 4 active threads on battery drain right now?
Hi
Had same problem.
Try to browse a storage card if its very slow You must format it and it will back to normal.
very strange but its working.

General battery drain yes, not the possible issue of a charger though. If I'm wrong I stand corrected. .

Hi Antrak,
Touch HD has the longest battery life of any similar 'phone. See e.g.
http://www.pcauthority.com.au/News/1...-the-rest.aspx.
Either your battery is not charging correctly, as you say (try it via the PC USB cord?), or you have two dud batteries in a row (very unlikely) or you have a bug in your m/board. 70mA in standby is too high. It should be <20mA with only the 'phone on in standby mode, providing you are not moving from one cell to another all the time, and have decent signal.
One other suggestion. Drain the battery completely to zero, then recharge it to max. This should reset the internal battery meter. But don't do this too often, as it ages the battery faster.
If none of these work, return the 'phone for a m/board replacement undere guarantee.
I have the same problem... After charging for 10 hours, my batt shows 55% only.. and last 1hr on STANDbY!!!
IMAGINE! charge for 10hrs juz to get to use for 1 hr.. im disappointed by the batt.. im not sure if HTC is gona let me exchange with a new one or do I have to buy a new batt..
try check your sync..its active all the time or not..
if yes..
find the threat to make a fake account for sync, so you can active it manually.
so your battery will stand more longer,
about charging..
me also facing the same problem..
need to change it more longer to get full battery,
but
if i change in my car,
no issue
very fast
i thing charger issue..
but i bought original set..
??????????????????
Okay I've charged my HD through my pc with a USB cable and formatted my SD card like a other user said. Gonna see how it holds out today. It could very well be that some chargers have issues.
My experience with the Touch HD says that when charged with a USB attached to a computer the battery life is a lot shorter than charged through a wall socket.

This is always going to be the case. Quickest way to charge your device will always be through your wall socket and with your device turned off!!
Same battery issue.
i recently purchased a new touch HD (T8285 telstra version) and am experiencing the same horrible battery issues. it takes more time to charge it, than i get use out of it.
i've tried multiple batteries, and am in the process of trying different ROMs.

Indeed, here's an illustration...
Image1:
Charging via USB takes longer. Consumption and therefore charge current is erratic after the battery level reaches 50% when charging via USB on my HD. So the battery fills up to about 60% of its capacity by the time when the battery level is reported to be 100% and charging stops.
Image2:
When charging with an AC adapter this is not happening and the capacity is fully utilized. This is also quicker.

That's strange. For me it's quicker if the device is turned on. When it's off it takes around 8-10 hours to charge but when it's on it's alot quicker.

If your device is on there is always power outage especially with programmes running, whilst if your device is off, there is no power drainage so device should charge quicker.
What rom are you using? software installed?

Latest official rom with alot of software installed. But it doens't make sence to me either. It's logical for something to charge faster when it's using no power (off) then when it is using power (on).
Combine battery threads ???
Hi to Moderators,
There are now several threads on the HD forum on battery and charging issues.
Can these be combined into one place and stickied, so we can get a clear picture?
Current threads are this one, plus:

I have a gut feeling from what I'm reading, that HTC have had a bad batch of batteries or charger circuits in the HD - in which case the best starting point is to call their service points and ask for help/replacement, instead of spending lots of time on other remedies. The symptoms described have lots of commonalities, and the HD is normally an excellent beastie for battery usage.
Thanks for all your help, ladies and gents! Your work is much appreciated.

Heya,
Don't know what it is but my battery life increased a tad. Am running Dutty's X3.0 with the 1.32.x.x. radio. Watching a 1 hour xvid dvd rip (no conversion) in coreplayer on full backlight with no HSDPA on, wifi or bluetooth takes away 20% of my battery, which is acceptable.
Don't think it's the SD card format though, it might be that I never have the activesync process on anymore by setting it to manual update and closing it (it otherwise keeps running.)

Hi,
I noticed the following problem on my Diamond 2:
If I turn off the phone for night charge it never shows green in the morning.
The only way to see that amazing green light is to charge the phone whent it is turned on.
Of course I applied the latest hotfix - no use for the off mode charging. And of course I wrote to htc - will not waste your time repeating their suggestions.
And I am not happy with my phone battery life - it hardly endures one working day - lets say - 10 hours...
ROM - Official, yet.

I never turn my phone off so the green light problem never arises. However I will check and see if occurs.
As for battery life, you will need to give it a few weeks of use before you see maximum battery life.
Make sure you don't continually discharge the battery (better still keep it charging whenever you can) and you should see improvement over time.
Unlocking and replaceing the ROM can also have a significant effect on battery performance as does the Radio version in use. That's going to need some work on your part but the improvements are there to be had.
Some apps that are in common use are also power hungry and can cause a significant drain on power.
And if you install your apps to mem card then again that uses more power than installs to phone storage memory.
You can also turn off any unused background apps and processes.
Only turn on Bluetooth and WiFi when needed.
All these things help.
Personally I carry a spare standard battery with me at all times and strangely since I bought it I haven't needed to us it. The placebo battery effect?
Thanks for the answer.
About the battery usage conseption:
You suggest that I plug my phone each time when possible?
I thought that as the battery has XX recharges according to the specifications it is not good to charge each time whenever you got AC or USB access
I started to follow your recommendation anyway.
For example however - my laptop is never (when possible) with battery in it. I use the battery only when necessary, becasue in the user manual is written that has 300 cycles of recharging. And I always wait until completely discharged before charging. That is how I began treating the Dimond, too.

With Lithium Ion batteries the "quoted" numbers of "rechage" is is an approximate equivalent to give some idea of life expectacy.
It's a hangover from the old NiCad battery days and is not really very helpful when applied to Lithium Ion usage.
The most important aspect of LIon is it's ability to hold it's voltge at max current for longer than other technology. It does this best when well charged and maintained at near max as possible as often as possible. The downside is it's life expectancy which does deteriorate over time.
If you require max daily useage then max charging whenever possible will give you this and you will have to accept that the battery will at some point loose it's charge retaining capabilities and will have to be replaced.
For most of us that's the most important thing.
This is not a battery issue, I believe that this is a software one.
I noticed this morning, having left my phone on charge, and 'off', all night, that the indicator light was still red. When I switched on the phone, it showed only 80% charged.
Having seen this before, I carried out a soft reset, the battery indicator then showed fully charged.
So the battery is charging fully, but the battery charge indicator is showing less than that.
Hello to all!
Since I don't have honor to post on main development page I need to post here in question!
I can't find nowhere something about battery life, I installed without problem ROM on my SIV and battery life is very poor. Yesterday I watched on YouTube MKBHD Hangout with Motorola CEO Dennis Woodside which have length of 39 minutes I think. My battery was at star 98% and at the time of ending video vas 45%. Battery can't last full day of normal usage. (it last from 07:00 to 18:00). At beginning I noticed this problem and I installed One Power Guard and its always on powersave or standby mode.
This anyone facing with this problem?
Yes mine is exactly the same. Running v4.0 and battery life is terrible now. Camera app force closes every now and then and sometimes maybe twice a week it reboots.
Plus I can't charge it switched off - everytime I plug it in it starts up.
Hi,
My battery is a little poor too, but it was because I was with my cellphone screen on almost the whole day... When it was an extreme case (when I was in 4.3 AOSP ROM and it didn't last even some hours, like you), I recalibrated it (I used to do it with my Xoom and X10 Mini Pro, it may be a placebo, but looks like it worked...
To recalibrate simply let your battery run completely out, then plug to the charger and let it charger completely while turned off (the white battery icon appears), then turn it on and let it run out again, then charge fully again. Remember that plugging and unplugging your device from the charger is bad for your battery, and remember to keep the screen brightness very low, turn off WiFi, Bluetooth and SPECIALLY 3G when you're not using.
Hope this helps,
~Lord

You need to flash v.6.0 which mostly correct FC camera app. I notec when i was runinng on ART reboots was more common.
My solution was to flash MK9 stock rom, this is the most stable and reliably by me so far.
