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.

How to disable USB Charging in Hermes WM6

Hi
I have upgraded my Dopod 838pro from WM5 to WM6 with the official ROM from HTC.
I connect my 838pro frequently using USB cable to my desktop to surf the net. In order not to ruin my battery, I disable the USB charging feature in WM5 (under the power ->advanced tab).
However, after I upgraded to WM6, this feature is lost. I tried the registry hack for WM5 but it didnt work for me in WM6.
Can someone help to let me know how can I disable USB charging in WM6? Thanks a million.

Why do you care? A brand new battery is around 10-20 bucks in ebay. I have been charging with usb for the last 4 months and didn't observe any significant battery life drop. I wouldn't mind buying a new battery for $15 every 2 years.
I would be changing my tytn in 2 years anyway.

I have been charging my previous battery frequently and it last only 5 hours from 100% to 10% with minimum usage now. That battery is only 1 year old. I have just bought a new battery and hence would like to preserve it abit longer until I have found my next good phone

Plenty of people have reported batteries going down quicker with certain ROMs, especially dependent on the radio version. Is it possible your battery is not the problem? Is the new battery definitely better?
When the light turns green it's stopped charging, so shouldn't overcharge. Li-ion batteries don't have memory problems.

It's not memory problems that these batteries develop. It's more that they have a certain number of charge cycles before their performance degrades. Most Li-ions I believe are rated to about 500 cycles tops before the battery life drops below 80%. So every time you plug it into the computer it would kind of count as a cycle. So a large amount of charge cycles and these batteries will degrade much quicker than normal.

Since 1 year I allways connect and charge nearly every day my little toy via USB. Never had battery drop. Even now with the new Radio and WM6 its works much longer as before.

I second that. It sounds more like a rom problem than a battery problem. After
all, there are people (including me) who keep charging via USB and don't
experience battery problems.

The last 4 months I've only charged my device with the USB connection and have no battery problems.
BTW: There is no way to turn the USB charging off, unless u cut some wires & remove some pins. see prior thread discussion:
http://forum.xda-developers.com/showthread.php?t=273344

I charge my phone like a million times a day it seems. Between car charger, home charger, usb from my pc. It gets plugged into things at least 3 times a day if not a lot more when I'm at home messing with stuff on it while its plugged into the pc. Battery works just as good as it did when I got the phone over a year ago. And working in the cell phone industry for years I still say that this phones battery life is amazing compared to most other phones. Even a year later this battery seems to last longer than any other pda battery especially considering all the things I do with it. ie: gps/irc/streaming audio/video via orb/talking on the phone with the woman. Can usually go 2 days of avg usage doing all that providing hsdpa is disabled. Once I turn on hsdpa I get almost a full day of avg usage.
Edit: All that being said, seems like a big waste of time worrying about disabling charging over usb considering how cheap a new battery is and how little a impact it seems to make anyway considering other peoples testimonials. Just my 2 cents.

Found this in Hermes Wiki:
Disable charging when connected to USB
Registry entry to control USB charging:
[HKLM\\Drivers\BuiltIn\Battery\EnableUSBCharging]
if EnableUSBCharging = 1 --> Phone will be charged when connected to a USB power (laptop, etc.)
if EnableUSBCharging = 0 --> Phone will not be charged
I have not yet tried this myself though.

Li-ion Batteries
I was doing some research about Li-ion batteries and came across this info - How to prolong lithium-based batteries.
Seems like the more you charge them and not totally discharge them the better.
Sogam

I have a DOPOD 838Pro which I upgraded to WM6.0 as well. The battery issue is well documented and has less to do with cycles or memory effect than it has to do with your settings. Upon upgrading from WM5.0, I noticed that the backlight setting for "on battery" was reset to half way. I normally used it on the leftmost side turning the display readable indoors. There is no point in setting the backlight to the maximum or even to the middle, as the screen provides poor reading outdoors anyway.
In my experience it increased my battery life between 25 to 35% taking an average working day, i.e. average number of hours on the phone.
Cheers

You can get a replacement battery here for only $7.29 shipped. Shipping takes about 2 weeks though but cheap.

Only had my Hermes a few weeks, but I've owned Compaq/HP IPAQ's for the last 6+ years. They always said in the manuals it was best to keep the device connected/charging as often as possible. Out of those devices I have only replaced batteries once for each device over the years, so I think it works well. My Hermes gets connected to my desktop at home and work most of the time, though I admit since its a phone and has better battery life then my Ipaqs I do connect is a bit less often.
That said, as others have written, batteris are cheap and unlike Apple devices, user replaceable. Thank you HTC!

Thanks alot for that. I needed it. My laptop used to charge when i connect my HTC Touch Pro, but then it stopped. I changed the registry you listed and it charges again.

Battery issues

Ok, this is just plain frustrating and I have no clue about what to do.
The lifetime on my phone is dropping ridiculously fast. I replaced the original batery (that used to get ran down pretty quickly, about half a day, without using the phone much) with a spare battery a friend gave me (it's from a different model, but a minor modification it fit perfectly. For a while, it worked somewhat more decently (although should I have used the phone, I'd lose about 1% for every 30-45 seconds of usage). But for a couple of days, it started wearing down a lot quicker as well.
For instance, just charging the phone and then leaving it without actually touching it on the desk will leave it at 88% battery life within about 30 minutes.
I've checked the processes to see if there's anything out of the ordinary, but everything seems fine. I'm thinking maybe the battery may have gotten damaged in the meantime since it wasn't the designated model for this phone, but I'm having serious doubts.
Also, I've ordered a new battery which should ship any day now. Hopefully it will solve the issue, although I'm considering getting a new phone.
Any ideas?
Also, the old Asus that I used to have (WM 6.0, standard keyboard) still has an amazing battery life, at least compared to the HTC (it can do about 3-4 days in standby, and 2 days with normal usage. Also, it's able to run for 12 hours while playing music and occasional web browsing. I can barely squeeze two hours of usage from my HTC)

Maybe you should get a new and proper battery to your device, maybe your fix does not work anymore. Also you can damage the excalibur motherboard if your messing with different volts from batteries design for other phones.

Well, the battery voltage is the same. So is the pin layout (well, that was pretty self implied). Both batteries are manufactured for HTC phones.
I guess I'll find out when my new battery arrives. However, my phone has been acting weirder and weirder. SD card issues, now the battery... And on top of that, I wonder if the two issues are related.
Edit: also, will the charger output make much of a difference? Say I use a 500 mA charger or a 1000 mA one.

Issue solved. Apparently it was from the SDHC patch I had installed a few days before. Removing the patch did not solve the issue (also, the patch disabled my WIFI) so I proceeded to reinstall WM on my phone. Now it runs fine, with regular battery drain.
I think the patch may have not allowed the CPU to enter idle mode. I can't think of any other explanation.

nah its definitely ur battery. i had the same problem, its that ur battert has degraded and it has become unable to withstand its charge. just call ur phone carrier and tell them. the should send u a free battery.

I know some HTC batteries are the same voltage, but why do you think they make different ones especifically for every model eventhough they have the same voltage.
Just to let you know and regarding the output charger; I did a little experiment once, with motorola chargers (V3) since you can charge your dash with them but I tried to charge the exact phone (motorola) with the original HTC output charger.....and it didn't charge at all.
After months of using the motorola charger I started to realize my battery was not working well in my excalibur and in a period of 4 months my battery didn't hold a charge for more than 3 hours. I bought a new one and I strictly used the orginal HTC charger.
My battery is 9 months old now and works like charm (2 days + hours) with the latest ookba 3vo rom.

[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.

HTC One Battery Extender Case?

So the battery life absolutely sucks on my One. If I start using it at 8am its dead by 5 pm. And that's just normal usage like surfing the web over WiFi, playing games (candy crush, dots, angry birds space,) maybe watching a few short videos over WiFi and the occasional text message. I have a battery saver app and I can see that it helps but I guess there's only so much it can do,Z so I want to get one of those cases that has an external battery built in. I have a few questions.
1. Does anyone here use one of these? Please give your input.
2. What's the best one? I've done a little research and found that the i-Blason and Mophie ones seem to be most popular. They're both a bit pricey.
3. How do they work? Does the phone just start directly using the external power after you switch it on, or does it just charge the internal battery?
4. Can these things have any kind of adverse effects on the internal battery from odd charging voltage or anything like that?
5. Do they actually extend your battery time as advertised? I'd be happy with getting two full days out of a single charge and some of these things are advertised as extending it by more that 1.5x. It seems like if the external battery is just charging the internal battery it would be a bit less efficient than if it were directly powering the phone. Does that make sense? It just seems like there couldn't possibly be a direct conversion of 2300 mAh from one battery to completely charge another 2300 mAh battery.
I hope that wasn't too confusing. Personally, I can't wait until lithium-sulfur batteries are in all our electronic devices (potentially 4x energy density.) Google it. Sounds promising.

1. I don't use these so I can't comment on this.
2. The iBlason and Mophie are the only ones available that I have ever seen. The Mophie being the higher quality (materials not necessarily battery life) of the two but also twice the price.
3. The phone will use the battery cases charge first then once that is drained use the phones internal battery. However if your phone battery isn't fully charged and you plug a charged case into it, it will charge the phone.
4. It's a good question and I'm not 100% sure. If you use it properly it shouldn't cause any major issues. Using it "properly" meaning your phone has full charge when it is paired with case so that the case isn't charging the phone. That being said, the damage is no different than someone constantly charging and discharging their phone in short bursts rather than using it until it's dead (or as close to possible) and then fully charging. The big thing to be aware of is that the damage caused is simply a reduced battery capacity and usually isn't big enough to notice during the life span of the phone (1 to 2 years).
5. Yes they do. Some of the claims may be a little higher than life experience, but nothing drastic. It litterally adds a second battery to your phone, so it IS going to extend the battery life quite noticeably.
One thing though, I have had my HTC One for a month or so now and have kept it stock, occassionally trying custom roms, but always going back. I have consistently been able to get over a full days use with WiFi always on, GPS always off, brightness always on auto, and I have exchange synced and set to push notifications. I am constantly checking email and texting for work as well as browsing the internet and Google Currents. I also have the power saver turned on. A full day use for me being from 8am to around 12am.
I think either something is wrong with your phone, you are playing too many games, or some setting or service is draining your battery. I would post your battery usage here for some to inspect. And it might be a good idea to uninstall the batter saver app, they usually don't make any huge dent on battery life that can't be done without the app, since most rely on a polling service that runs in the background and eat up battery life themselves. Just make sure your sync settings are reasonable (not every 5 minutes), turn off GPS and only turn it on when needed, don't turn on WiFi unless you need it, turn off 4G unless you need it (switch to CDMA only in mobile settings), enable eco mode (power saver that throttles CPU based on usage), and make sure brightness is set to auto or a medium to dim setting.

Mostly right. I'll toss out though that cases have different current outputs-- the mophie cases will output at a high enough rate to cause a phone to register as being on AC. the i-Blason case charges at about a third of that rate, meaning that it'll trickle charge your phone/reduce power consumption rate, but it won't outright charge unless you're not using it.

1. I've used one for about 2 days. I returned it. It works well and the Mophie definitely feels of high quality and feels great in hand. However it makes the sleek device very big and bulky.
2. I would recommend the Mophie purchased at your local corporate carrier store, reason being is that usually your carrier will offer a 1 yr warranty on a premium case like this. However if you break or it shows ridiculous wear and tear they wont. I cannot comment on I-Blason's warranty. Although I think the Mophie is perhaps more expensive. Some carrier offer discounts based on employer's of the account owner. So that might help get the case cheaper.
3. See comment below
4. Usually since they're molded directly to fit your device, most manufacturer's will accommodate the OEM's requirements. But the Mophie charges as fast as it would if you had plugged it into an AC charger.
5. This question is a bit more confusing for me to answer. All I can say is that if they advertise a 100% charge then that means they're matching the mAh capacity of the device. (Ex. phone model has a 2000mAh battery internal and the case advertises 100%, then that means the external battery is also rated at 2000mAh.) So in reality if you're expecting a complete 100% charge while your device is still on, then no, you may get from 1% up to 70-90% depending on how much you're using it while its charging.

This is not entirely true. Because the Mophie has an on/off switch. So if the case is set to off, it'll use the internal battery first, then you need to switch the battery case to on to begin charging the internal battery. It is entirely possible to use the phone till it completely shuts down when it run out of juice and the Mophie have a full charge.
It uses the same charger as the phone itself so the case never has to come off, however even if the switch is set to off it'll charge both items at the same time.

1. I've used one for about 2 days. I returned it. It works well and the Mophie definitely feels of high quality and feels great in hand. However it makes the sleek device very big and bulky.
2. I would recommend the Mophie purchased at your local corporate carrier store, reason being is that usually your carrier will offer a 1 yr warranty on a premium case like this. However if you break or it shows ridiculous wear and tear they wont. I cannot comment on I-Blason's warranty. Although I think the Mophie is perhaps more expensive. Some carrier offer discounts based on employer's of the account owner. So that might help get the case cheaper.
3. See comment below
4. Usually since they're molded directly to fit your device, most manufacturer's will accommodate the OEM's requirements. But the Mophie charges as fast as it would if you had plugged it into an AC charger.
5. This question is a bit more confusing for me to answer. All I can say is that if they advertise a 100% charge then that means they're matching the mAh capacity of the device. (Ex. phone model has a 2000mAh battery internal and the case advertises 100%, then that means the external battery is also rated at 2000mAh.) So in reality if you're expecting a complete 100% charge while your device is still on, then no, you may get from 1% up to 70-90% depending on how much you're using it while its charging.
This is not entirely true. Because the Mophie has an on/off switch. So if the case is set to off, it'll use the internal battery first, then you need to switch the battery case to on to begin charging the internal battery. It is entirely possible to use the phone till it completely shuts down when it run out of juice and the Mophie have a full charge.

I was not aware they had an on off switch, that would change the way the phone handles the device and give you a bit of flexability in how you use it, which is good.

I wonder if it would use the case battery first if you turned it on when both are 100% charged. Everywhere I've read, people seem to use them to charge the phone after the battery gets low. It would be great if the phone would just draw power from the case until it dies and flip over to the phone battery. I feel like that would keep the phone battery more healthy by avoiding inconsistent charging. If you're constantly killing the phone battery and using the case to recharge to less than 100%, then killing it again... it just seems like that would be bad for the battery.
Thanks everyone for the input! Keep it coming!

Good question. My thoughts would be that the phone would only draw enough to keep topped off. So I guess if the switch is left to the on position the whole time you would get the desired effect of draining the external pack first. But I would guess that doing that would reduce the efficiency of the case somehow.
In the end whether your constantly killing and charging your battery no matter to 90% or 100% with the case or A.C. charger, doing it more often will kill your battery either way. Given lithium ion batteries are way more forgiving than the old cadmium based ones that built up a memory of sorts.

To keep the battery healthy in a phone, make sure you charge to 100% each time. You don't need to fully drain battery, it's actually healthier to go from 50% to 100% than 1% to 100%.

So if my phone only gets down to about 40% each night before I plug it in to charge all night I'm ok? In the back of my head I'm always wondering if I need to drain it all the way sometime.

You are fine, it's better to not drain the battery all the time. It lasts longer if there's charge left. You just have to make sure your fully charging to 100% and not charging only to 70% or something like that. This is how lithium batteries work in all devices, laptops etc...

And either way you wouldn't notice the loss in capacity until you at least 2-3 years out.

So I've been thinking about this a lot over the past few days and I have something else i want to throw out there...
If you have your phone plugged in to a charger while at full charge, you can use it all you want and it will never go below %100. Does this mean that it's completely drawing power from the charger, or is it still drawing power from the battery, which is just constantly being topped off? Because I know I can completely remove the battery from my laptop and as long as it's plugged in to the charger, it will continue to function just fine.
If the phone is drawing 100% power from the charger, doesn't that mean that it would do the same for one of these battery extender cases?
Like I said before, I think that would be a lot more efficient that just using the case to recharge your phone's battery after it gets low. This way you sort of cut out the middle man.

BTW... I found that there was a weather app that I think was constantly trying to access my location even though I have location services turned off. I now get a good 10 hours of battery life with moderate usage. Still want a battery extender case. 2 full days would be awesome.

HTC battery life DOES suck compared what it can do because you are not going to buy a phone like this if you wont chat/text/call/email/play games alot. Mine lasts 10-15hours (usualy 2.5-3hours screen time and NEVER more than 3) and thats annoyng because its ok if im just ordinary home-work-home rezime but if i need to go out of the city for lets day 2-3 days - im screwed and allways must think about charging.
I have overlooked everything nothing wrong with the phone - the battery is just too small.
i keep wifi ,gps and bt off if i dont need them but my phone ofcourse syncs everything (thats the point of a smartphone - to be connected!) and i play often also.

Nope its being topped off, phones are all about maximizing space in the phone, it would require more wiring for the motherboard to be able to draw power directly from the micro usb port as well as the battery. For example, my Samsung phones can be plugged in but if I take the battery out the phone turns off.

I got this one - all day w/o charging w very heavy usage. Traveling w/o signal - 2-3 days no charge. Makes the phone bigger and you can't see the gorgeousness of the phone, but it protects it all around and it lets those 4 cores and crazy display to do its job w/o dying on you fast.
This guy sells them for $20. Have seen them in other sites for $70-130. Same exact model.

You just don't know how to manage wakelocks. Do some reading. Mine lasts almost 2 days with 5 hours screen on time.

1. I have the i-Blason black.
As a Case
Pros: Great volume controls, Black matches the black HTC One and the black earbud plug, kickstand, central USB plug.
Cons: Thick, Gets Warn when plugged in
3. There's a button that turns charging from the case on or off. Phone will be like it's externally charging.
4. The i-Blason is a lower current charging, so there's a warning that pops up. I think it's not harmful.
5. Extends, yes. But >1 day, no. Well, if you're not using the phone, yes, > 1day. What I do is I let it charge the phone when I'm not near a usb plug and it gets < 80%, then i let it trickle back to 100% in about an hour. It automatically stops charging the phone at 100%.

Learn how to manage your phone guys. Track down the offenders instead of buying these battery packs and other nonsense.
