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.
When I got the jasjar 3 days ago there didnt seem to be any issues, so I upgraded to the Helmi_UNI_AKU3.3_v1.2 everything seemed to work as it should then my battery reached 40% and bam the device shutoff. So I tried the 3.5 and same thing, now I have my original ROM JASJAR_WWE_13076_164_10900_wwe_ship.exe back on and its a little better it gets to 33% then dies.
I know this wasnt happening prior to me owning this device as it was my close friend who gave it to me.
Can anyone shed any light on why this would be happening?
Thanks in advance.

You have to buy a new battery. Your battery is damaged. A few months ago I had the same problem. The Universal battery has a life spam of 6 to 12 months. At a certain point when you drop your phone or flash a new image, the battery forgets its state. It will think that there is enough power left but in fact the voltage is dropping to fast and the phone shuts itself off. Believe me you need another battery.
Thank you
Thank you very much for your advice, I just ordered a new one.
So when I flash new roms I should use my old battery?
Thanks again
Question
Does anyone know why batteries die so fast.
I had a battery the first go out at 20% then it grew to 55%
I couldn't use my Universal for a day.
I went back to the store and got a new battery.
I think, when you flash your device with a new rom and or radio. You should have your device fully charged.
Can anyone confirm?
Not sure on the answer, but I have 2 batteries, one 12 months old the other 2 months old & the Uni with 3.3 on it started this behaviour yesterday whichever battery it is using - roughly 30% left.
I am upgrading my other Uni to 3.5 just now to see whether that one suffers the same.
As I have a new battery & am having the same fault I am not so sure .....

It is a hardare issue, unlikely a software issue.
I do not agree. At first I had the same idea. I thought the device must be broken. I bought a new battery but still I had the same problem. But at the tech center thay gave me a free new battery to prove I was wrong. I got a original MDA PRO battery and when I use that battery it stops working at 2-3%.
1. So order an orginal battery. Use the old one when flashing.
2. Be sure that the battery is fully changed. Flashing can skrew-up the memory state of the battery. When that happens the current sate will be te fully charged state and it looks like it stops at 40%. But in fact it is does never get fully loaded.
This issues have already being discussed and sort of already concluded in many other threads, you can make a search.
Just to summarise,
1. Most of them agree it is a battery problem. Lithium Polymer is no good after around 6 months.
2. Few isolated cases of not battery problem which is hardware related.
3. I always activesync with my old spoiled battery (this is just my personal advice as I do not want to risk my new battery). This also avoids USB charging.
4. Charge only when LED is RED (less than 10%) and until LED turns GREEN (real 100%).
Add 2 more O2 XDAs with HW probs
Mine and a work colleagues Execs (bought early Jan 06 under their ****-up £99 scheme) both started to shut down at odd power reserves as in this thread. Both had new batteries, both before and since new batts sometimes wouldn't charge or recognise the power cables.
Also, both have been back to O2 for repairs with the result when they come back, one is in exactly the same state as before, and the other (mine) stck in splash screen. Both came with a note from O2 saying problem found and repaired, and even a QA check slip (ie:evidently no QA - are they pulling a fast one or what?)
Anyways, both are going back to O2 to try again.
If you are in warranty, get it back to them. Wait for the battery by all means but my experience says this is more than a battery problem.
Sorry, thats not what you wanted to hear I know.
Joe
Hope you get your Hardware problem fixed, like those cases mentioed in the other threads.
Mine is the battery problem like most cases mentioned in other threads.
My new battery now can goes from GREEN 100% to RED 0% to complete shutdown is possible.
But I normally charge around RED less than 5%.
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

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?

Hello people, after having used my Touch pro 2's GPS function extensively one day on battery, I have realized that the battery's life has shortened by huge amounts of time. It lasts for less than 24 hours now, so I was wondering if I needed a new battery or is there something I can do to restore it back to the previous state. Thanks!
I don't think using the GPS should ruin your battery, just doesn't make sense! Are you sure you shut off the GPS after using it? Are you running any other programmes in the background? Did you flash a new ROM?
My battery started going down twice as fast after swapping to the new "official" Sense 2.5 ROM.
you can try a couple of things that may extend your battery life. try first turning off the auto speakerphone when the phone is face down. i just did this and i can tell a marked difference in just a couple of days. also search battery life reg edits. theres a ton out there here and on ppcgeeks that will definetly help. in general i noticed that when I use GPS the battery drain is pretty high. hope that helps

Using the GPS all day will def drain your battery much faster, especially if you're using aGPS and/or an app that also downloads data to compliment the location info (like google maps). The GPS radio isn't 2-way like the phone or 3G or wifi, but it's still a radio and will give a noticible hit on your batt life when used even moderately, let alone all day.
If you're going to be using GPS a lot, you might want to try different radio roms to see if any of them make a difference in the batt life for you, but I don't know that will make as much of a difference as it does for the phone reception, etc. I would also suggest evaluating various GPS apps, with an eye on relative battery drain
Well guys, thanks for the answers, but that still doesn't solve my problem because I don't use the GPS function often at all, but the battery still drains quickly. Also, there are no programs running in the background. There is however a data connection that is always on and the mail checks for mail every hour. But the thing is I don't want to change any settings to enhance battery life, If it worked fine with the same settings before, why wont it do the same now? Do I need a new battery? Thanks!

Ahhh sorry, I misunderstood, I thought you were just saying it drains faster while you use the GPS like that, not since you used it...I get it now.
That one day of heavy use shouldn't have killed your battery, take a look at THIS thread, others with the same issue/question have posted different things that have worked for them...you might want to give the steps in post #31 a try before thinking about buying a new batt.

You can install " battclock " and you can continuously see what the battery drain actually is during different functions.

Yes, great recommendation! (why didn't I think of that? lol)
And with battclock you can now see your CPU usage in real-time, which is probably one of the best coincidental indicators of battery drain (much more so than memory load, in my opinion)
Hi Dimitri,
I experienced the same problem where my battery life suddenly "shifted" from 48 hours to 12 hours on regular use..
I thought the problem was the battery and I replaced it, this did not help at all..
The only cause of this problem that I can think was loading the official HTC UK 6.5 ROM (1.86.401.0)..

This is exactly what I am experiencing. (This together with not being able to connect the device to PC)
Installed several 6.5 ROMs and suddenly the battery lasts only half a night.
My question is: When the battery is full, when you turn the device off (completely off, not in standby mode!) does the battery drain then?
As far as I see, the battery has only 50% left after a night rest while it is off. So, the only way to keep the battery full is to remove it from the device.
What are your experiences with this?

If you are truely turning it completely off, the battery should NOT drain at all. Have you tried a new battery? I bought a pair of batteries and an external charger on flEabay for like $12. The batteries are good as originals as far as I can tell.

Yes, I have two batteries, even an external charger.
Even when a battery is charged with the external charger, then put in the phone it drains the battery
hey guys can anyone link any of the forum topics to tweak battery life? the only things I have done is the general setting on the phone and the power management options with advance config are there more options and tweaks available?
thanks for all help!

My question is: When the battery is full, when you turn the device off (completely off, not in standby mode!) does the battery drain then?
As far as I see, the battery has only 50% left after a night rest while it is off. So, the only way to keep the battery full is to remove it from the device.
What are your experiences with this?

Bright light...I'm also having BOTH of those problems...stock ATT rom. Within the past week my battery life has dropped exponentially, and when I went to sync last night, had not done so in a week or so, I get nothing...none of my PC's will recognize the phone as even being plugged in, let alone sync. I'm thinking maybe an ATT botched update?

So it seems I'm not alone.
Mine is a universal one, no brand whatsoever. I will try to reflash the original (6.1) stock ROM, including radio.
Have you flashed yours already?
@Bright.light @VirtualHomer:
I have the crap battery + no activesync issue.
I'm on the Josh's Black 1.7 ROM. I tried hard reseting, reflashing, going back to the stock ROM, but no improvement.
I have heard that removing the battery overnight is a possible fix for the USB issue (maybe for both?), but I haven't tried yet, will try tonight.
If anyone out there has any potential soultions here... would be great. Right now, I only get 1/2 a day (~6 hours) out of the battery & no hotsync at all (other than BT).
One thing I am pretty sure of: The bad battery life and the activesync issue came up around the same time. Wierd.
Cheers

You are right in assuming that battery life and connectivity issues came at the same time.
I was assuming this was because of a (bad?) flash, or maybe a bad ROM which changed something in a position that should not be changed and which is not restored by flashing another ROM.
A night without battery won't help, I think, because my device has been numerous times without any power and without any battery. However, I will try it again.
Could this be a faulty device? Or a design error?
@Bright.Light
I confirm that a night without the battery solved nothing. I have had my phone on for 5 hours now, taken 5 calls, none of them too long, checked email every 10 minutes (automagically) and I am down to 27% battery.
Also, I confirm that a replacement battery solves nothing, as I have also tried this.
I am planning on returning my device to an ATT store next week for a replacement... We'll see how it goes.
Cheers,
Matt
I'm in the same boat with mine. About two weeks ago the battery just started draining fast. Fast enough that it wouldn't make it to 4-5 hours without being charged. You could watch the battery meter drain. And what was weird was that there was no ROM change or anything that started this. Came out of the blue. Calling Spring tomorrow and getting a replacement is the best solution I can think of.
I've had my new desire z about 2 weeks now, and am utterly dissapointed by a frankly dreadful battery life.
It's my second DZ, given the original was nicked, but (kicks self) wasn't insured, so was purchased from a supplier that shipped my phone from Hong Kong (I live in UK, and the new phone is an identical model, except for a slight difference in key layout - A2727 I think is model number)
The original phone would give me over two days life with very low use, which i considered to be fair for a decent smart phone.
The new phone barely gives me 10 hours with no use. I've done a couple of tests - unplugged it at 2am, but 8am it's at 30% or lower. This was done with all data connections turned off.
If i leave the new phone to go dead then that's it - it won't charge. The only way i've found to get juice back into the battery is to hold it in my old touch-pro 2 until it's charged enough to charge from the desire.
Last night was the clincher. I've gone out with some friends to the pub. I had a conversation over it, and checked my battery life - 42%. As a last dith effort i factory reset the phone at that point to rule out a mischevious app, and checked - 39%
Within 2 hours, and with no use at all that was down at 8%. In order to avoid the charge issue i cut my losses and turned it off at that point. Once home (oh, about 4 hours later maybe) I was unable to turn it back on. I then left it plugged in overnight, and was still unable to turn it on this morning until i'd done my cross-phone charging trick.
I'm now entirely convinced there's some form of hardware issue at fault here, so i'm wondering if anyone else has had the same problem with this phone before? I see lots of thread regarding poor battery life, but most seem to be solved by turning data off or some rouge app, neither of which are an issue in this case. Also, any hints for making my life easier when I phone HTC tomorrow? I've read elsewhere their support might not be all it should be.
Thanks in advance for any help! I've ready to pull my hair out as what is a fantastic phone otherwise has been completely ruined by this battery issue.
I think you should get a new battery to rule out that the battery itself isn't a problem. I had similar issues with my G1 a while back and it solved a lot of wierd, seemingly unrelated problems. Batteries are pretty cheap online, $15 or so and some are free shipping.
The way that I figured out my battery was toast was by comparing it to other batteries. it had a bulge in the center where it should have been flat. Fingers crossed it isn't hardware.
had already tried a diff battery (did you know you can chew a corner off a touch pro 2 battery and make it fit??) Which i know worked fine in the old nicked dz and imo as i was getting same issue ruled out battery problem.
anyway... phone has now been returned and i'm waiting 2-3 weeks to get it repaired under warranty (though am hoping for complete replacement obviously)
Chewing on batteries has got to get you extra xda brownie points. I'll remember that

I'd like to think there was some techincal or engineering skill in there somewhere.
but it was mostly "Well, apart form this nugget of plastic they're the same shape..."
I'm having the exact same problem... When you take you shutdown to recharge a dead battery, does it sometimes try to turn back on? I left my apartment like 30m ago with 100% battery, and I'm at 84% and declining. There's nothing running. And I've replaced the battery, same issue.
I think I might just RMA this one.. seems like an engineering issues.
Edit: I'm the 40 seconds it took me to type this, battery dropped to 82%.
Wanted to bump this post. I've since wiped / reloaded and wiped battery stats. It's still jacked. I think it's an internal electrical thing. Reason is: I'll power down to take the battery out. When I put the other one in, it'll turn back on. Or if I power down to charge, it'll turn back on - plugged in or not. I don't want to deal with the RMA process again, but I think it's my only choice. I've taken two phone calls this AM @ 100%, and it's at 96% now. Drives me insane. Ugh... I'll call TMO. Anyone know if the replacements are still rootable?
So... I had my phone replaced, and it's still doing the horrid battery thing. Flashed CM 7.1 RC3 or w/e the latest is, cycled one battery - and it drops like a stone. I have two chargers (one at work, one at home) and they both charge the phone up to 100%. But it's still losing battery life quicker than I'd like. I used to be able to get a good 18 hours out of this phone. Even with a new battery and a new phone, it's acting up. I'll try to flash an older ROM and see if it's the same thing. I updated to #130 nightly from 7/10. We'll see how it lasts today. But I do remember I had horrible luck with CM's ROM's on my G1. Battery would just drain for no reason. The main process taking up the most battery life is "Cell standby" so I changed to the latest radio - and it still drops. OP - have you figured out your problem? I've removed a ton of apps, and it's still messing up. I listen to music for... 45m in the AM, and I get down to 54%. I've formatted my SD Card as well.. it's driving me insane.
I just flashed CM 7.1 a few days ago and while the ROM is great, it does seem to be a litter harder on my battery than 6.1 was. With light/moderate usage yesterday, I got about 16 hours and that was running the battery almost completely dead. With heavy usage, I get about 10 hours and need a bump charge in the afternoon.
You might want to look into getting a Mugen 1800mah battery. You can get them on Ebay from 35-40 dollars. The seller 'nakedcellphone' is based out of Southern California and another user has confirmed ordering from them and getting a legitimate battery (lots of fakes on Ebay). Either that, or carry a charger with you...
Have you tried using Watchdog to see if there are any 'rogue' apps that are causing the drain by running in the background? What about going to spare parts > battery history > Partial Wake usage? There it will show apps that are draining your battery when you're not 'actively' using your phone. For me, the Android System is the highest drain in that menu. Good luck! Hope some of this helps!
I just checked spare parts, and there's nothing too odd in there. Just my music app. And I've changed that too - thought Winamp was killing me. I'll check Watchdog. This is a brand new OEM battery along with an RMA'd G2. It has to be the OS / Radio or something. I've stripped like every non-essential app too.
