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.

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 Problem?

Hey,
i have a problem with my BA.
as soon as my Battery is as low as 60% or so if i hit the power button it does an automatic restart. It even restarts every 2-3 minutes when i want to use Wlan.
I tried another Battery (but both are around 4 years old) and there seems to be the same problem.
I also tried a hard reset, but the same problem occurs. So i think it has to be a hardware problem.
Can there be any other problem than the Battery?
Thanks

does any one have an idea?

Recently, I've had the same problem. At one point, my unit dies and reboots at 59% and is not usable until I recharge it. Now, it dies and reboots at 79%. Further, it drains from 100% to 79% in 4 hours on standby - barely used. I'm assuming I need a new battery.
I'm thinking about getting a 3600mAh, but it looks thick and my unit might not fit in its leather case anymore. I'm trying to figure out the thickness of the 3200mAh battery, but I can't find pictures showing its thickness.
I've been reading here that some people mentioned these batteries do not charge in the cradle. I'm not sure if it is user error or fact, so I'm nervous about buying them.

Try a new battery. That should do the trick.

Definitely I'm sure it's the battery in my case, but do you think one of those 3600mAh or 3200mAh batteries will charge on my cradle? That's the real question.

it will charge but I don't know if it will fit in...those batts are a lil' bit thicker than the normal one...

it has an adapter
With the craddle comes an adapter A serial with the Jack to the AC port... of the craddle...

I just realized it wont fit in the cradle. But yes, I'll have no choice but to use the AC adapter.

Charge Indicator Inaccurate with 3600mAh Batteries
As a note, the 3600mAh battery charge indicator drops at the same rate as the OEM 1490mAh battery. There's probably more juice in the 3600mAh battery but I assume WM2003 is only programmed to read 1490mAh batteries.
Also, be careful with losing your memory using the 3600mAh battery as it has a tendency to fall out due to its size. Because the battery stick out further than normal, a few times I've pushed the battery out of the locking position and lost all my memory.

Hmmm... Let's point the topic back to the RESTART problem. It has happened to me too. Sometimes turning off at around 70-85% battery left. And pressing the power On restarts the BA. Sometimes the Mobile cannot also display Network.
I am particularly suspicious on the programs we might have installed and not the battery itself. Here are some of the softwares I have installed and uninstalled (uninstalled included as they may have messed up also with the system). Maybe you can also point out if you have identically installed some of which that may explain the problem.

I am only using 4 accessory programs that I've used for years. My problem started years after that. I'm sure it's the battery because even with the same programs and a new battery, the problem is gone.

What's your battery life like? (WM6 & WM6.1 welcome)

I'm curious to know what other people experience in terms of battery life. I've just put a fresh 1500mAh battery into my phone, and I've flashed it with two ROMs in as many days.
I got average battery life out of the first ROM I tried (Schap's v4.31 Full), but I'm currently running with CRC's Release 13.3 Stable (Build 20270) and I can - literally - see the battery life ebb away in front of my eyes. From the moment I unplugged it, the battery went down to 99%, 98%, 97%... slowed down at 94%, but it's carried on going down.
The phone's only been unplugged for about 3 hours, with moderate usage (occasional use, installing a couple of apps, a lot of time just sitting by my computer) and already the battery is at 79% (one minute ago it was at 80%).
I can monitor the power consumption with BatteryStatus and it does seem to be using more power than you'd expect just idling - 43mA with the phone idle, bluetooth turned on and paired to my headset and the backlight on. With the backlight off completely, it's still using between 25mA and 50mA! Is this to be expected, or is something sucking the battery power up?
Is WM6.1 just a thirstier OS than WM6, or is CRC's ROM particularly resource intensive? I have done a little tweaking, but mostly doing things like turning power management ON (to lower SD card power usage) and installing a couple of extra apps (none of which are currently loaded in the background).
If people have a particular ROM which has very good battery life, please let me know - I'm interested to see what people are using and what kind of battery life everybody is getting.
Cheers

Battery
Where did you get a 1500MAH battery for a herm? i could only find 1350!!!
I'm using Black Satin. 6.1pro but it doesn't have anything fancy, like manilla 2d or stuff its really basic. With 3g turned OFF! the phone doesn't overheat. As soon as the phone gets a little hot the battery just drains for some reason. I believe that the 3d card when its turned on it must not have signal everywhere and as soon as the connection is broken if you step outside of the coverage area it tries to find the signal and BOOM! your phone is dead! battery just drains.
on the average day ill take it off the charger around 8am. and just leaving it on standby not doing anything its usually dead around 5pm...
And this is the Black satin rom so far out of all the roms i tried it has been the best for power consumption. There is a guide on the "Best" tested roms in the stickie... its a great starting point. Some of the top rated roms didnt work for me cause i needed to install some 3rd party software for work ... and they didnt work, im guessing cause there was some stuff that was stripped out.

it is not only about the rom. it is also about the battery you purchased.
I have an old original battery which is about 4 years old. I also have a cheap brand new battery I purchased from china. The 4 year old battery holds more power than the cheap brand new one. I found that the new batteries are not properly initialized, or that there is something wrong with how they report the remaining power. My new battery drops down to 60% percent very fast. Then it hangs there for a long time and then starts going down very fast again. In standby it gives me 2-3 days. With wifi turned on, I get about 20-30 minutes. The original battery gives me a couple hours even with wifi turned on.

what you say makes sense, when i called HTC about this overheating / Battery issue they told me that they didn't specifically make batteries. After reading a bunch of posts there seems to be different models from different countries of the hermes. After looking deeper into the battery issue there are also different manufacturer of batteries from different countries also. The thing is HTC can not tell you EXACTLY which on you need cause each operator has different standards for the phone some even modify the phone from HTC... When i called Expansys which was where HTC recommended i purchase the battery from they had 2 models. 1 that was 1300mah and 1350mah. I Opted for the "House" brand instead of the other one which was cheaper in price ... I guess this is the reason. Like memory when it is made in JAPAN its quality is not the same as KOREA.

I agree with regards to the battery quality. That's why I only buy Cameron Sino 1500mAh batteries for my Hermes (I buy them from Morpeth Mobiles here in the UK, they also sell on eBay and I'm sure they'd ship international if you wanted to buy from them).
They handled a recent return excellently and I've been very happy with their service.
The nice thing about the 1500mAh batteries is that they fit inside the case without a replacement back cover...
I know that using 3G can suck the life out of our phones given the awful chipset (using it on GPRS only or in 3G with a very strong signal will always yield better results) but at the moment I'm not sure if it's a problem with this particular battery or with the ROM itself - I have two others with which I can do some comparisons, so I will be doing that later. However, the battery life today has been awful. I got home earlier, and less than 12 hours after being unplugged, my phone was down to 18% battery. Just awful, the worst battery life I've ever seen from my phone. I'm not sure whether it's the fact it's Windows Mobile 6.1 or whether it's a problem with this particular battery or the way the ROM has been cooked... I'll have to do some more experiments, but I know for sure that something's not right!

The roms Also do play a part i beleive, some use up more memory and have processes running.. this uses power. Its the same as a LAPTOP. The LT will not last forever.
But im really dissapointed with the Hermes. i had NON touch screen HTC's . s640 and S621 and they used to go for days on end without charging...
i herd some back feedback on these touch screen phones also ... about the life... but every time also the 3g would murder the battery life!

Although on balance, I still don't think our phone does that badly... You realise that it's almost on-par with the more recent technology, particularly when you hear some of the battery life horror stories from iPhone users, who are dismayed that they can't get more than 12-15 hours' use out of their beloved phone when they attempt to do anything vaguely like USE it (push email, multimedia etc)...
The saga continues.
I may just buy a petrol generator on a small trolley and attach the whole thing to my belt. Now THAT's ultra portability. I could use my phone on 3G for days!

I picked up my Hermes from another xda member a week and a half ago. I flashed to CRC's stable 13.3, added HTC Home and a few other extras, nothing real system heavy or anything. Battery life was abysmal with bluetooth and 3g turned OFF, 3 email accounts syncing every 30 min, on the original 1350mah battery - I was lucky to last half a day.
I ordered a 3000mah extended battery, it arrived yesterday, I let it drain completely. It's fully charged and running now. I have bluetooth and 3g on, and my email accounts are syncing every 10 minutes. I will monitor the battery life over the next few days and report.
I too have noticed the battery meter being very eratic in CRC's stable rom for both batteries. I'm not sure if this is a battery issue or a rom issue. I may try turning 3g off as some have suggested and see if that yields better results.
My previous phone for 8 months was a Motorola Q9H, so I'm not exactly a noob to the winmo world. With the q's extended battery and bluetooth/3g on I was getting a good day and a half to two days with a rather large amount of data use in there. Honestly, as much as I love the upgrade to winmo pro, if the extended battery doesn't do the trick I'll be back to the moto for the remainder of my contract and the Hermes is going on ebay. Anyone with any suggestions or tips would be appreciated.

Thanks
Yep i just installed CRCs Release 13.3 Stable... Looks nice, but i think you are right .... im stuck with this clunker for now cause i need it for work but im waiting on a Touch diamond... As soon as my company can afford it! LOLOLOL
Let us know about the 3000ma bat... Is that the one with the HUGE back door that sticks out?
I seen that online and though to myself.... WTF the phone is already too big!!!

What's your battery life like
I have an HTC TyTN that originally had Windows Mobile 5. I flashed to the rom to 6.1 pro and also noted a significant power drain that I didn't have with 5.0 or 6.0. My thoughts are that moving from 5.0 to 6.1 is much like going from Windows XP to Vista. The power demands are greater. At least that's my hunch.

Roms RULE!
Well i tried all these roms ... The Manilla roms look GREAT the touchflo is really cool!!!! But dam the phone doesnt have enuff ram or juice... So what happens if you get all kinds of bugs ect...
But if you try some of the other 6.1 roms like Black Satin or CRC which dont have touch flo ... the bat is not soo bad... The lite verisons of the roms can also be nice .... But they lack support for other software.
i prefer the classic Windows with the home cause you can use the Screen Lock feature ... specially for the HTC Herm ... i always had it in the pounch then all of a sudden i would pull it out and IE was open!!! or i was calling someone LOLOL that sucks!

i have tried lots of roms that were developed here on xda.
the best battery life was using k's final wm6.0. it was unbeatable.
the other thing is that it also depends on the type of storage version of the rom itself. the big storage roms eat your battery for breakfast but you get better performance.
if you have more today plugins they also eat up the battery
you also should, before flashing your new rom, flash the original rom. after that you flash the normal rom.
you can also check the processes running in the backgroung, maybe there is something left over that occupies the processor.
3g is a big drainer especially if you get to an area where the signal is weak and dissapears. then the phone constantly tries to find the 3g and your battery drains quickly. normaly, when i don't go online as much, i keep 3g swiched off.
now i'am using the new wm6.5 beta and i get more than one full day of battery life of normal usage. phone, mail, internet...

Yea the extended battery turns the Hermes into a tank. It does have a nice feel to it in your hand though, and my Body Glove universal case ($15 walmart) actually fits, although its snug.
If the battery doesn't give me the life I'm looking for from CRC's 6.1, I am considering flashing to the stripped down version of ATT's 6.0 rom, or perhaps trying out the new 6.5 hybrid build from josh. Who knows, maybe CRC's rom is just a battery suck (which I can't imagine it is, it's pretty stripped down/light weight). I guess we will see after a few days here.

NICE!
i would like to try 6.5 .... but i cant seem to find any links with screen shots... If it has any sort of Touch flo ... Forget it ...
Do you have a link to 6.5 WWE?

Interesting about the comments re: big storage eating battery, and interesting also that other people using the same ROM as I am currently are also experiencing battery life problems.
I just swapped out the battery in my device - from the brand new 1500mAh battery to the older (identical) 1500mAh battery, freshly charged. As soon as I got to the Today screen, the battery was already down to 97% - and just sitting on my knee ticking over, it's already gone down to 94%. 93% now!
This is ridiculous. The battery life in WM6.0 is the same (just as bad? ) as the original WM5 ROM I had on it, it's mad to think that a simple point release of an Operating System can cause such a massive difference to battery life.
However, this ROM may have Big Storage enabled, so that could be sucking the battery life out of the poor thing. Does anybody have any pointers or links to previous discussiong about how (or why) Big Storage drains the battery more than a regular ROM?

the best 65 ROM so far and with relatively good battery life.
i had the same problem with the battery life and came to realize that NO rom is good enough in thus area.
i guess that is a small price to pay for free OS
i would also recommend you to try the original ROM for your country or WWE and check his battery life for a few days - you will soon find out that the more application you will install you'll get more processes that are running in the background = less battery life.
if you can live with the default WM - you wull get the best battery life.

Hehe, unfortunately the ROM which came with my phone was from my phone provider - T-Mobile UK - and it is awful! Broken Bluetooth, huge lag on the phone because of all the preinstalled crap, almost no free device memory, slow to respond generally... All of these new ROMs I've flashed make my device feel so quick again! It's amazing what a small change can do.
Has anybody cooked a WM6 ROM without the honeycomb Today screen interface? And is it totally impossible to go back to WM6/6.1 after you flash 6.5?

[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,
Regards,
Dave

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.

[Q] BA battery life only 2-3 hours?

Hi all,
I'm a noob who was happy to get a BA to use instead of a Pocket PC/ MDAII. I thought the battery was no good so bought two new ones (1490mAh).
But even these only give me about 2-3 hours, with all possible power saving settings in use (brightness, beams, bluetooth off, power down if unused etc.).
I've searched and read up a lot on here, it's an excellent forum. I've flashed the ROM from the original 1.12 WWE (I think) to various ones I've found on here using WM6 and WM5 claiming to give good life, still getting nothing better than 3 hours even when left completely idle .
So is there a common hardware fault known for draining the battery? It certainly seems battery life is a common topic here for BA, but I can't see a phone that gives less than say 12 hrs use per charge having ANY success in the marketplace, yet the BA is regarded as pretty popular.
I'm about to bin it and go back to the PPC, or worse the Nokia.
Any ideas please for troubleshooting or remedies before I do that? One strange thing is even when it's idle the back is slightly warm to touch, so I'm thinking of either an invisible rogue application running or a parasitic current drain in the hardware.
All help and suggestions gratefully received.

But even these only give me about 2-3 hours, with all possible power saving settings in use (brightness, beams, bluetooth off, power down if unused etc.).
I've searched and read up a lot on here, it's an excellent forum. I've flashed the ROM from the original 1.12 WWE (I think) to various ones I've found on here using WM6 and WM5 claiming to give good life, still getting nothing better than 3 hours even when left completely idle .
So is there a common hardware fault known for draining the battery? It certainly seems battery life is a common topic here for BA, but I can't see a phone that gives less than say 12 hrs use per charge having ANY success in the marketplace, yet the BA is regarded as pretty popular.
I'm about to bin it and go back to the PPC, or worse the Nokia.
Any ideas please for troubleshooting or remedies before I do that? One strange thing is even when it's idle the back is slightly warm to touch, so I'm thinking of either an invisible rogue application running or a parasitic current drain in the hardware.
All help and suggestions gratefully received.

get an extended life battery

SOLUTION found
The clue was the warm battery
A repair guy over the phone said it was probably water damaged, sure enough the "white spot" inside was showing VOID in red.
So I opened it up including some of the sheet metal covers on the board, and used cotton buds and methylated spirits, cleaned off some deposits.
Put it back together and it's now had >100 hrs of standby time and is still over 50% on battery meter.
Now on to finding a ROM I like and starting to use it.
