Hello -
I'm having an odd problem. Even more odd is the fact that I can't seem to find a single post from anyone experiencing the same symptoms. I recently upgraded my HTC PPC phone to the WM2003SE Special Edition ROM (And have tried a custom cooked SE ROM as well), and am noticing that ever since, for whatever reason, the pda is no longer using power from the external/extended battery. The power settings screen shows that the add-on battery is recognized, and when in the cradle, it shows that both batteries are being charged normally. However, when the unit is undocked, only the main (internal) battery seems to deplete (and my battery life is obviously significantly shorter than it was pre-upgrade). The extended battery shows 100% charge, even after hours of use.
Is this a known issue with 2003SE? Is there some utility or (registry) setting that's required to enable the unit to draw power from the external battery when running SE? Any help is much appreciated, as I love WM2003SE, and am really dreading going back to an older ROM. Thanks in advance for any assistance.
the extended battery is a reserve of your main battery used to protect your data when the main battery depletes ...
Theres no way (at least i think) to "enable" the extended battery for normal use.
It kicks in when the main battery reaches 0% and last for 72Hours but you cannot use the PDA in this time, its only there to retain data.
If I hadn't been using this pocket pc for over a year now, I might accept that answer. But in previous OS versions, that's simply not how it functioned. For clarification, I'm talking about the piggy-back extended battery, not a 'backup battery'. It extended the life of my pocket pc by well over 100% and the meters would show it depleting alongside the main, internal battery, not sitting at 100% as it seems to do now. The battery life of my pocket pc is now literally 40% of what it was pre-upgrade.
I do appreciate your response though. Any other thoughts? Any other people experiencing anything similar?
Hi, i may be assuming the wrong thing but to be clear ive attached a picture of what i mean.
Sorry if its not the same as you describe.
He is referring to the additional clip on battery not the backup battery. I cant understand why it doesnt work correctly, I thought it was a straightforward electrical connection that needed no driver or registry entries. I think you will need to flash back to original rom to see if this is a hardware or software problem.
Cruisin' is correct. And yeah, that's pretty much what I was thinking would be the next step (downgrading and testing to ensure it's not the hardware) assuming I saw no obvious answer here. Thanks, cruisin. I'll post my findings when I get the time to test with a previous ROM.
And thanks to you too, danny, for trying to help out.
sorry for maybe my silly questions.
anybody know how to connect external battery? I want to say complete wiring diagram between phone and external battery.maybe I can try to emulate external battery with some high capacity accumulators like 4XR20 (4xA size in other standard).other solution is to charge PPC from that external device,or maybe better to have dual function switcheable,external battery or charger.
any info or documentation is wellcome.
Are the external monitor and CF card slot features on your backpack working properly with SE?
If not, I bet there are backpack drivers contained in the original Himalaya ROM that are missing from the new one. The SE ROM, after all, was derived by modifying a version taken from a different device and adapted for the Himalaya. The backpack is Himalaya specific.
This is of interest to me because I currently use the excellent Diamond ROM and have been thinking of adding a backack for presentations.
Perhaps one of the gurus could help?
RE
Hi!
I'm using my 3rd backpack now for my O2 XDAII WM2003SE.
There's no need of any backpack driver if you upgrade from WM2003 to WM2003SE.
Secondly, you can't change anything in the main ROM AFAIK. However, for the EXTROM there's no backpack driver required.
Thirdly, the backpack battery lifespan is pretty short as compared to the main battery since during usage the backpack battery will reach zero first. Hence, it won't be surprise that the backpack battery can be charged to 100% and then reaches zero after a short use as compared to normal usage. This is a sign of impending end of life of your backpack battery.
How long have you purchase your backpack? If you charge your O2 with your backpack daily (after the backpack battery reaches zero) then likely that tha backpack battery will not last 365 charges i.e. a full year.
Otherwise, it could be sign a of faulty backpack. My first backpack failed after a few weeks of normal usage. My 2nd backpack failed after nearly a year of normal usage.
I suggest, if possible, take another backpack and test to see whether ist your backpack thats giving the problem or do a hard reset and re-install your OS again.
i have original batt XP-09 made in china..
what type of batt the best used in atom life?
coz i have XP-09 if overhead can not charge. i not try with another batt.
what is problem? batt problem or device problem? i check service center and say no problem.
need advice. thx
Hi,
I also have an XP-09 made in China. It also overheats but it never fails to charge. Does your battery charge under normal circumstances?
hmm.. i charge normaly.
if i use for internet sharing 3G the batt getting hot and cannot charge.
now i am charging normaly. coz i only use play mp3 and transfer mp3 via BT from PC.
can u give me photo ur batt xp-09? thx
ok. would upload as soon as i find a spare camera..
ok. don not so long time
My mwg atom life was bought in the UK from expansys http://img201.imageshack.us/my.php?image=img0701az2.jpg
I had this problems with my atom life and it was XP09. Since last month the device suddenly stopped booting using the battery. Device will boot when it is connected to the charger but, it is slow and the display becomes colorless. I can see that the device isn't detecting the battery any more once it is booted. I dont have a clue what happened to the device. Can any one give me a clue? Thanks in advance!
what is the different of xp09 for atom life and xp02 for atom exec?
i see both 1530mhA, 3.7v
i try xp02 on atom life, no problem
just wonder what is the different?
See this thread. It covers most of the issues you're asking about.
Well members,
I really want to know who has their battery percentage the same as in winmo. I know it has a issue with the battery driver, but still i am curious.
My battery.capacity=4462 Units.
Current percentage in Android 41% at the moment
Current Units in Dmesg 2988Units
After restart in Winmo it says 53%
If I calculate this, (2988/4462)*100= almost 67%
Someone knows what i am doing wrong?
PHP:
I will charge my battery again tonight, plug usb out, read units, change Units again in default.txt. Then I will keep for myself updates trough the day of the current data. Will post again tomorrow with updates.
Hope to hear what other people are experencing

Yeah is really not understandable of how to calibrate the battery, iv been trying it for the past 2 weeks...and i still have not get it right! well..i got 4320
My battery reports completely wrong in android, to the point where it's 30-50% left then dies as it's really flat!
Hmm,
Code:
Try to use this line in default.txt if you don't got it yet
board-kaiser-battery.battery_capacity= ****
**** stands for the unit you get in with Dmesg in terminal of android after a full charge.
I can say that doesn't even is correct for me.
But I Tried another value. I read (translated) on japanese forum dat you have to put the mAh instead of units.
So I tried with 1350 (Of my Kaiser160).
Now my android shuts of when it's 15% instead of 59%. He also said something like, try to double the value. I am testing now with the value 2700
You guys should try :O
I've to say, after changed to 1350, i had a more realised idea how android does with the battery. I can say that android sucks more battery than winmo.

Hi there, well iv tried the above instructions, but i found out something is strange, i deleted the batterystats.bin and then make sure that the board-kaiser-battery.battery_capacity= 1400 (my battery is 1400) i adb pushed it to my device....but strangely when i reboot....it changes back to 2700 automatically....i think this is the reason why we still cannot calibrate our battery for now...since as soon as my battery reaches down to 20% and suddenly 4% then shuts off...
Perhaps do you guys think that to keep our kaiser's stanbby time longer rather buy an external battery charger and make sure that battery is charged up fully.so that we can utilize the battery fully.
i think for now we should just try an carry our chargers with us say to work or school..and charge it over night....
Usually i wouldnt charge my phone for bout 2 days but it will last..but now i realieze its a must if ima use android..
Cheers
i never trust the battery status when charging.
if I am looking for a full charge I wait until dmesg reports a charge of less than approx 30mA. if it shows charge at 100/100 and it still is showing over 100mA then it is not done charging.
also if it is showing less than 30mA and a charge of less than 100/100 it really is done charging. don't wait for 100/100 if it is done charging.
as far as battery usage is concerned, one thing to not as far as a difference between winmo and android:
winmo shuts down many services when sleeping.
such as in winmo if you are playing music and it goes to sleep, music shuts off.
and same for wifi.
android doesn't seem to shut of anything except the screen.
maybe there is settings for what is to be run while sleeping.
I had a program in winmo that allowed you to turn on or of services during sleep.

yep...you are right....maybe we should just focus on dmesg for now...by the way, do you guys have the same problem as i have...20% then suddenly drops to 4% then shuts off?

i dont have that problem..however today, i charged to 100 percent and talk to my gf on the phone for about an hour..it went down to about 40 percent..i set it down and didnt touch it for about 20 minutes..and it went up to about 70 percent..very weird
Yes, i can tell you, in the settings under connection (i think, i have dutch android language) you can define a setting that wifi goes to sleep after your screen sleeps.
Code:
Also,best way to use android is that you have to
1. fully charge your phone in android and keep the powercable on it,
2. look in dmesg for the units. when te units aren't getting bigger, than that's the last one that is charged.
3. write down or do something with your mind :D
4. restart to winmo, KEEP POWERCABLE ON
5. change and/or put a line to your default.txt "board-kaiser-battery.battery_capacity= ****"
change **** to your units you have written down
6. after you changed units, start to android.
But still it doesn't is good yet. I experienced that 1350 value is the most effective one. When android said 15%, i tought lets restart and look what winmo says. winmo was at 1%.
Also, i was a little cocky and without 100% battery i started android. I can say, it took ages that 100% was changed to 99%. Also you never know when battery is going to die
Maybe someone can do something with this.

i think for now...we should just look at the charge in dmesg....which is the most accurate telling for now...

try to put these lines in sysinit.rc:
#battery patch
chmod 777 /sys/module/board_kaiser_battery/parameters/battery_capacity
write /sys/module/board_kaiser_battery/parameters/battery_capacity 1400
I'v changed it to 1350. It was charged properly and drop to 4% from ~10%, so nearly ok. But when connected charger it's full in about 10 minutes????
Edit: After dischargine (5 minutes), it charges probably normally.

Thanks! i think it worked now!my battery now runs down normally...
How long everybody using your Kaiser battery? I can use 3 days in Winmo but it could not exceed 1,5 day in Android (NAND) :-(
I have the same as you.
But i stopped using Android on ma phone. I'am out with Winmo, don't want to use it anymore. And android dies just quickly.
Am using now en Nec N343i
Will try android again when new updates or new kernel arrives
yo ppl...now most of the time i can figure this type of stuff out....but this time im kinda lost....i edited the sysinit.rc file....also the battery_capacity file.....im running poly 2.1g on NAND but after i reboot the phone....does nothing.....any tips or site with a little more info...?? thanks in advanced for any help

Hi,
I have polymod 2.1 gamma with all updates (UPDATE 15 Mar 2010, UPDATE 18 Mar 2010, UPDATE 23 Mar 2010) and the kernel from "ponack.net/poly/BT_Update/" installed on NAND (Tytn II). It runs really smooth, but I have a problem with my battery.
I have written the battery patch from tiagoclc in the sysinit.rc before I installed on Nand (but with value 1350 from my battery). But is this enough or do I have to delete a *.bin file from battery? I hope someone can help me with a description.
I have seen a fix for "Myn's Warm Donat" here:
forum.xda-developers.com/showpost.php?p=6243182&postcount=306
Is there also a fix for Eclair 2.1 available? Or does someone have a "complete" description for this battery problem? My Batterie is a few hours on 100% with this battery patch and I can not charge it. But this could not be true.
I hope someone can help me.
MT
Maybe kernel problem.
I'm experiencing the same problem as everyone.
Lately my battery suddenly drops from 100% to 4%.
When I put to charge, it reaches 100% very fast. Should reach only 5%
I think it can be a problem in the kernel.
Now, i'm trying to solve it. If I find something I'll share with you
I can not determine which kernel brought the problem...
23/04 - 16:16 (GMT-3 - Rio de Janeiro) - Trying an old kernel
23/04 - 17:00 - Nothing. But came to the conclusion that the problem is with the battery.
Battery really "thinks" its 100% charged, since it accepts flash a nbh without the need of the phone is charging. And this only happens when the battery is at least 50% charged...

We must concentrate everything in one thread!!!
We have to use search
I have set 1350 in sysinit.rc and it seems to be ok, but before every charge I have to reboot to charge it fully. then it discharges nearly fine - there are some fluctuations beetween 2-3-4 percent.
I have an issue on my HTC desire as the battery gives me constant values:
- battery voltage: 3923 mV
- battery temperature: 24.3 deg Celsius
- Current:
* either constant to 8mA (after a full charge the current says 8mA for some hours if phone is in standby)
* or constant to 44mA (whatever I do, playing games, browsing, watching movies..., or doing nothing)
Those values can be obtained with the secret menu (*#*#4636#*#*), using the apps "Battery Monitor widget" and CurrentWidget, or from kernel logs (cat /proc/kmsg in terminal emulator).
Apart from that my phone behavior seems to be normal, and the power consumption seems ok.
For some it might not be a big issue but, as I am trying some ROMs and different kernels, I would like to get the real current used (in mA) in order to really test the power consumption.
I did already did some tests to understand where the issue come from:
- full wipe (cache, data, dalvik) to get a clean ROM
- try a different battery (battery reference are both 35H00132-06M)
- change ROM and kernel
but I always get the same values !
That's why I suspect the issue to come from the battery sensor.
Now here come my questions:
1- Did any of you already had such an issue ?
2- Is the Battery Current sensor and Temperature sensor are the same one ?
3- Where are located those sensors ? In the phone or the battery ?
4- Do you think this wrong values could lead to strange phone behavior or damage the battery ?
Thanks for reading this boring post and even more thanks if you have some answers !
If the battery is being used in the same way as another battery then the results will be the same. If your getting 44mA from using your phone then good. Power consumption is low. By turning the screen on and not doing anything, I get to about 120mA. To be honest, this just seems normal, nothing wrong here. Unless I am missing something everything is fine.
My problem is that every returned value is a constant, I don't see any changes in terms of current if my screen is off (even in airplane mode, nothing running) or if I play a game.
I still get the same current, voltage and temperature values. That's why I suspect the sensors not to work.
Now I would like to know where are located those sensors (in battery or in phone) and if this sensor issue could lead to potential problem... I suspect it could damage the battery.
Anyway thanks for your answer, regarding your 120mA with screen on is it a normal value ? how long does you phone lasts on a battery cycle using CM7 ?
Testing the sensor
mmh, my question does not seem to passionate lots of people
I have a new element, I installed the apps called z-DeviceTest and Temperature sensor is said to be not working.
Is there anyone who could try this app on his HTC desire and see if the problem comes from the app or from my phone.
Once again if someone could answer the following questions, it would be quite helpful for me:
Is the Battery Current sensor and Temperature sensor are the same one? and where are located those sensors ? In the phone or the battery ?
problem solved !
I went to the shop where I had bought phone and batteries and I made some tests together with the reseller using Battery Widget Monitor. It has been easy to find out that the issue was coming from the battery.
Actually I was unlucky, I had bought 2 defective batts ! Or at least the battery sensor was defective. The batteries seemed to work fine but because the sensor was broken I think that after some charge-discharge cycles the batteries might have been broken.
So in case you have such a problem, just try another battery.

damn it, it happened to my battery as well.
I have experienced the same problem and reach similar conclusions.
More details are given on my blog 78michel.unblog.fr
Looking more in detail to this battery caracteristics, I am now anxious about one point:
You observed , and I confirm :the temperature is always at the same level.
Looking more deeply at safety IC for LI-Ion battery , it seems that the NTC which normaly gives the temperature of the battery has also a safety component which prevent from extra heating and fire.
If the temperature is constant , may be it is beacause the NTC have been replaced by a resitor. This means that there is no longer any safety system active!!!!!
I am trying to check this point.
I have the same problems as mentioned above. Always constant 3923 V and constant mA drain.
I have bought 3 batteries from different sources all have the same problems
2 batteries have the S/N 35H00132-06M and 1 with S/N 35H00132-01M
The only battery that is working is the one that was shipped with my phone.

i have the same problem with voltage indicator - 3923 mv even my phone is low on power or fully charged!
strange issue....
someone did find any answers till now?
i'm try'ing to change my rom from cm7 (7201) where i am now to another rom to see if problem persist.
i'll be back with some conclusions...soon!
I'm seeing the same issue with 2 bilitong gold batteries. Despite them claiming to be 1650mAh they test at little more than half that with jumps in the % left reported rather than a smooth reduction The batteries appear to be 'genuine' bilitong batteries as they arrived in the blt packaging and not just a battery with a lable.
They also only charge to 99% and the charge light stays orange when powered on although the charge light goes green when its switched off and charged
I would surmise that these effects are seen from batteries which are trying to hide what they actually are. aka the manufacturers disable, or more likely do not include the protection circuitry which
* reduces the cost of manufacture
* decreases the losses through the battery as there is less control electronics to power/incur resistance losses
* prevent reporting of what the battery state is and is doing hence indicate its true capacity.
this would also explain why some folk say that a battery melted/damaged their phones.
Unfortunatly there are a lot of 3rd party batteries for the Desire who have bugged electronics inside.
I tried several 3rd party batteries before ending up with an original HTC battery, that works fine.
It seems like all those companies just buy the same electronics, assemble it with the cells and case and put their name on it. (polar cells, andida, etc.). They maybe check the values once, and because they seem legit, they think it is ok.
Im afraid those electronics are a big intended fraud, because the output seems made up to not be perceived so easily...
Unfortunatly sellers and manufacturers seem dont really care about their broken products, because most people just buy them and dont check for sensors or dont give a ...
But I do see some serious risk here, as others pointed out before:
if the temperature reported is always 24°C , the device would not switch off loading when the battery starts overheating, like it would normally do. IMHO this could lead to serious damage to the battery, device and surrounding.
If you get one of those batteries, I strongly recommend to get your money back.

Agree fully, especially regarding the overheating, which also likely means the CE labeling is false or at least unjustified outside of any tested ones.
Temp reported at 24.x even when phone is hot.
Mv always reported at 3923
Claims 1650mAh (or anything from 1500mAh up to 3500mAh in other Chinese batteries) but shows between 2-3 times the power drain of a old original battery (@ about 1100-1200mAh of original 1400mAh) whether under load or in standby if battery power set to 1650 in monitor utility, which means they are probably only about 750mAh real capacity at best under normal load.
I see when searching that shenzhen Himax (presumably not to be confused with Himax tw) seems to make some bilitong brand batteries, but there does appear to be a separate shenzhen bilitong unit/factory in poison province China (shenzhen, Guangdong Province).
Its quite likely the companies are related, and they may well be the sources for many if not most of these crap batteries. Its notable that these 'branded' bilitongs despite their very pretty and professional looking packaging had nothing on them stating a capacity rating, so anything could be claimed.
Pretty packaging wrapping a turd..
Happy to revoke this view if I am given any verifiable evidence (preferably me testing) to do so.
Just testing a bxt (baixt) claimed 1600mAh blue coloured battery which seems OK at least. (NOTE - not the gold coloured bxt with ridiculous 2450mAh claims).
Voltage seems to be reported OK although temp is wildly inaccurate in the one I have.
Seems to be testing roughly 1000-1200mAh with low standbye drain
So seems very OK at the price
Note this is testing on my backup zte blade/san fransisco where the standard batteries are lower capacity than on the HTC desire:
(1250 vs 1400)
Dear xda community,
my problem is that my battery level says my battery is charged to 4432 mAh (checked via couple of battery calibration apps), interesting thing is, that the max capacity of my original battery pack is only 3000 mAh
Things that may occured by this is, that my phone reboots frequently if i plug it off the charger. It does this in a way which makes it for me unusable, because it did not even load further than the lg logo in the bootloader, only way to fix it up again is to plug the charger back in. I tried flashing a new rom, an older rom (where these problems never came up) and also flashing the latest kernel.
I'm currently running on cm-13.0-20160309-NIGHTLY-d855.
Hope somebody can identify the problem and help me out
Best wishes,
LoCk :3
dude ur battery is gone.i had the same problem and the only fix is new battery.so go get a new one ok,it will solve ur problem i guaranty u that.
