Upgraded to WM2003SE, no power from external battery.

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.

[Q] Strange battery problem

Hi all,
My battery drains really fast, faster than normal if I see the replies to the calibration thread. After less than half a day (as in 6hours) with wifi turned on and "playing" a bit with it (exploring apps, check them out etc.), say about 2hours of intensive use, my battery is at 25%. It never lasted longer than 24h, that's with wifi off most of the time. Running CoPilot it lasts only 2-3hours. I tried the calibration for nexus one posted in android dev forum several times, including battery stats wipe. It's at 29% but overcharged says 3762mV, also if fully charged it never goes above a certain V which I don't remember right now but I'll post back when it's fully charged The V it stays at is a lot lower than the replies on the calibration thread said it should be, that's why I'm think my battery doesn't charge fully.
I'm running LeeDroiD with no setCPU.
Is this behavior normal? Do these mV's correspond with the batt %? (29% <> 3762mV)
Thanks!

I'm using Leedroid as well, but I don't see excessive battery usage.. Most of the time I can survive for > 12 hrs..
from my Desire + XDA App

I have the same problems as you with a short battery life, I upgraded the battery to one with a larger capacity but that makes no difference, I have been told that this is a common problem and a fix will be out in the near future from HTC.
I also use Co-Pilot and when I ran it the battery could not keep up, I bought a car charger from e-bay and it may be a fake and I now have the new charger with the USB plug and that works ok, if you have a car USB charger try using it with the original sync cable, if the battery stays full then the old charger is at fault. My understanding is that there are a lot of fake chargers and accessories out there and they look the part but do not supply enough power to run with the phone running Co-Pilot.
Hope this helps.

A lot of the extended batteries on the market are well below their advertised capacities (see here). I've not heard of any official "fixes" for battery life, but then again I get 30+ hours from a charge,

Yeah I'm not gonna buy a non-genuine battery; simply don't trust them.

I have spoken to HTC about the battery problem a few times and according to the guy I spoke too there is a patch that will be released soon, I dont know the exact details but it is supposed to help the battery life, my phone would be dead if I ran Co-Pilot for an hour.
I am now using a 1600mAH instead of the standerd 1400mAH, the battery is the same size as the original and was supplied from a trusted manufacturer. I have also killed my task killer and will wait and see what happens, some people say that its not neded or HTC would have built one into the software, so I will give it a go for a week or so and see what how it works out.

Well hope this "patch" helps and it'll be integrated in the custom roms. However, a task killer isn't necessary because of the way android is designed. Apps get hibernated as soon as they don't require any interaction/resources anymore (eg. Load a webpage and immediatly go to home; Internet will load its webpage and as soon as it's loaded the Internet app goes into hibernation so effectively its killed just takes some ram (i think), at least it doesn't use any resources at this point anymore).
Services, however, run continuously and do indeed take battery the whole time.

Phone randomly turned off

I've had this phone for about 2 years i think (is there a way to tell the exact days?). It was working fine until about a couple of weeks ago. It starts to randomly turned off by itself. I would call somebody or pick up a call and using text message and it would just turn off by itself. But when ac adapter is plugged in, no problem at all. Not sure if it's the battery or something else.

according to my personal experience it is because ur battery is not holding charge any more... it happens with most of the batteries..i had same problem. my battery would require 5 to 6 hours to charge and it would b empty with in 1 hour..it was in the beggining later my battery would not even open my phone without connecting it to AC adaptor.. So you can now buy a new battery.. increase the life of ur battery by doing following things:
* when u buy ur battery charge it to at least 8 to 10 hours
*do not use ur device when it is charging.
*do not use Internet sharing with ur new battery.
*do use ur old battery if u r sycn ur device with PC for long period of time.
* Use Omap clock to reduce the overclocking.. it provides bit long battery life..
hope this helps...

Thanks. there are batteries for $2+$3 shipping or $9+fs. Hmm, decisions... Should i trust these?

Why don't you measure the capacity of your batteries? It is easy - lookup the thread in my signature.
For the Excalibur the battery drain with full lit display (all radio parts off - keyboard lights off) is 98mA. So roughly 10 hours will it last until the battery is flat. I had measured 2 different batteries in my device and their data has produced the attached chart in Excel.

[Q] Z2 Battery replacement in a Z1?

Does anybody know if it is possible to use the Z2 battery in a Z1 ?
My battery has always been really good until a few days ago, now I am lucky if t last half a day, without use!
So I wondered if the size of the battery is the same on both, if so it should be a bonus to get 3200mAh instead of the 3000mAh on the original Z1 battery. :good:
So if anybody has done this or know`s if this is possible, please give a feedback, so I can order the battery that will give the most
SOLVED: The connection is not compatible, so I have to go for a original 3000mAh battery

Ur problem can be:
ROM/kernel which doesn't handle battery correctly, if u changed it recently.
If u changed ur ROM recently, next time while flashing try to wipe battery stats as well.

Hey, Thanx for the reply and tips but I have had the same kernel/ROM for quite a while now (Ihackers 6.2 and Ihackers advanced Kernel 6,2 ) and have not had any issues before this. The only thing is that I have not been using stamina mode because the battery life was more then good enough without it , but after turning on stamina mode the phone have been working fine again, so I really dont know what happened the 2-3 days I had the xtreme battery drainage
I will try turning off stamina again and see if it happens again, then I guess it is some kind of bug or app that drains the battery and not the battery itself that has become weak... :fingers-crossed:
Too bad i did not test that out before I ordered a new battery
But it is nice to know that I will have a new one on hand if the need for replacement comes to a reality, it wont last forever

Haha happens to me all the time, I realize I should have tried something else before pulling the plug .
BTW any new app that u installed, which requires either GPS, Bluetooth or Wi-Fi the whole time?

Battery level to high

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.
