Hi Guys
I work in the IT dept of my company and ive got the job of supporting all our WM devices. (97% of them are the HTC Tytn II/Kaiser)
i get moaned at alot about this things and the main thing is the battery life is p*ss poor! All they run is active sync to pull in emails as they arrive and then the usual phone call, but yet the battery still wont last a day.
Does anyone know of any tricks or tweaks i can do on the devices to make them squeeze out every last drop of battery life?
cheers
Yeah, if you can get Advanced Config installed on their phones, fire it up, go to the right soft-key "Menu" option, and in there should be a Comm Manager selection. Pick it, and in the panel that comes up check on teh 3G button. Then, close out of Advanced Config and let it reset the phone. When the phone comes back up, go into the Comm Manager and there will be a new button to turn 3G on and off. Turn it off. If all they're doing is phone calls and pulling down emails, the Edge connection should be more than sufficient. I've also noticed improved battery life by leaving bluetooth turned on all the time (I now it's counterintuitive and could be a placebo effect, but I swear it makes a difference for me.) I can get well over 2 days on Edge connection with the stock battery using these 2 tricks.

If they don't have them already, you may want to have car chargers installed in the company cars of those with TyTN IIs. As for settings yes disabling HSDPA or even better going back to just plain GSM rather than 3G will help battery life (although also slow down any internet connectivity). You could also try turning down the screen brightness as this has a major effect on battery life but then they'll probably all complain the device has p*ss poor screen visibility (especially in bright sunshine - so if you're in the UK this won't be an issue )
If these suggestions don't work then I think the best plan will be to make it as easy as possible for them to top up charge during the day, perhaps with desktop cradles as well if this would encourage charging. I sometimes need more than one battery charge in more than a day (I've even used up all of my spare battery charge as well on a day involving lots of GPS navigation on foot) so yes these things do normally use lots of battery power if you have all the bells and whistles running and no charging occuring. Make sure wifi is left off on the TyTN IIs unless it's actively being used at the time.
Which ROMs are they using - all HTC official? There are reported differences in battery consumption depending on the ROM version used.
cheers for that guys
I will give both of your suggestions ago, next time i get one of the tytns in front of me.
I have the advanced config for the HTC diamond would that work on the tytn? if not where would i get that from?
Is it just me or are we being left with the sour taste of "Why should we have to compromise on the performance of the device to get 2 days battery life out of it?"
Unfortunately " push " email kills an already suspect battery. Activesync and your media net ?, edge? or 3G remains connected all the time . I had to go from " when they arrive" to " check every 30 minutes " for email or else my battery , even with minimal use would not last past 5pm.
I really miss my Blakberry in this respect. My Tilt does everything and everything for me, and does so on battery power. I guess if it just made phone calls the battery would last for days.
i agree denco, all the HTC WM devices ive ever had, they've had a load of functions but the battery is all very weak! whether or not that is something to do with HTC or WM i dont know, but its very annoying and just something we have to live with as my company signed a 2 year contract with Orange in March so there is nothing we can do!
Well, I doubt that it is Windows Mobile; ok, to be correct: WM has gotten more powerful with each new version, got even more and more graphical additions, just like Vista compared to XP. For sure this needs much more horse power and, in fact, processor and RAM are increasing. However, HTC barely increases battery capacy as well - might it be because of size / weight proportion or other reasons - I don't know!
I had the MWg Zinc II for a while and the battery life (1500mAh capacy) was amazing. However, audio / network reception quality was a joke on that thing.
Thankfully, there are HIGH CAPACY and EXTENDED BATTERIES available for the HTC's. They make your device look funny but surely increase your battery life as well.
I am (still) willing to sacrifice battery life for quality; arranging my life by having a car charger and also a 2nd battery with me when on the go. Hopefully HTC's batteries will evolve and have higher capacy in future devices.
Kaiser battery life
I am not an expert at this. I also was unable to keep a battery operational for half a day until I did a hard reset, and brought it back to stock ATT 6.1. Then used the phone without email for a day and noted no excessive battery drain. (70% at end of the day) Kaiser tweak added, with the “Disconnect after” parameter in the Data (GPRS/EDGE/HSDPA/WIFI) set to 1 min. Added the MS Push to my Exchange server, and only use the single email account. No appreciable battery drain. (68% at end of day)
The only thing I have NOT enabled yet is the ATT Navigator. Will add Google Maps and see if it messes with GPS chip. I have read and experienced the GPS draining my battery, even after turning it off, within a couple of hours.

In the advanced config, there are also settings for "Power management", make sure there is enabled in all of them.

Nah, considering the EEEpc I have gets about 2 hours battery max, and I can do a stack load more on the TyTnII than on the laptop, I', pretty happy. I had aan old Nokia that would go for 2 weeks without charging, but for a high end, gps enabled windows phone, 2 days is amazing.
@ splash08 : you can also try upgrading to the new 1.70 radio found in the kaiser rom thread, seems to give me less drain. Also, you can buy larger capacity 3rd party batteries.. maybe thats the best soultion.
GPS (Telenav) causing my battery drain
Since my last post on the 27th, I have had ZERO problems until I used the Telenav on Friday evening the 5th. Since then can only get about 4 hours out of the battery before it drains completly and that is with ZERO use. I have uninstalled Telenav and done multiple power down, but stilll draining. Looking for a way to turn off the GPS before I do a hard reset.
GPS had no issues with google maps and no battery problems.
ive now tried all those suggestions but non have really made a dramatic increase. I thought i cracked it at one point, over a weekend my phone last from saturday all the way though to monday night! but then i realised that saturday and sunday is off peak so the push/pull function was set to every 60mins! As soon as i got back to work during the week the device would last just over one day, on emails only.
i think i may have to look into getting the extended batteries or maybe changing all the devices for a none HTC device, as they seem to have a weak batteries (but i think this may be the last resort at it will cost a lot ot change all the devices)
Hi all, searched and couldn't find what I was exactly looking for.
when i first got the phone, the battery life was short but since a couple of weeks ago, it's gotten much, much worse. i've had the phone for maybe a month or so.
i'm talking about the battery draining 10% in 30-40 minutes on standby with nothing like bluetooth or wifi on. at least the phone used to hold a charge decently if it was on standby, now it drains like i'm using it even on standby.
what are the greatest factors that affect battery life? when i first got the rom i have now, it wasn't this bad so i don't think it's the rom itself. plus i absolutely hate changing roms (it takes hours to get all my settings back)
some things i thought of:
i could use g-light but i noticed this makes my memory use quite higher and this doesn't do anything for when it's on standby anyway.
how often the accelerometer checks for rotation, right now it was at every 200 millisecond. I've changed it to 750 now, i'll see what effect this has.
same thing for light sensor. right now it's at 500 ms now.
radio. but again it was fine at first with this 1.09.25.23 radio.
anything else?
With my original 900 mAh battery the consumption was about 15% every hour. This was with the data connection always on. Without this on, it would last 2 days at least.
I also loose quite a bit of power when I'm in a bad phone reception area.
But not knowing where the battery consumption is being used up can be very annoying.
Whenever I'm abroad (and thus have all data connections disabled with NODATA) I always get a massive boost to battery life so it could be some process sending/receiving loads of data that you're unaware of? To test that you could install NODATA and kill all the data connections temporarily to see if that helps? Not that that would narrow down what was happening completely but it might help point you in the right direction.
i also suspect it might have something to do with data. what i've noticed is that my emails don't download fully, only the titles download and i think it stays connected while it's 'stuck' trying to download the rest of the messages, i notice this because it says in the menu 'stop send/receive' meaning it's still trying to send/receive. normally, i have it set to check every half hour. but i guess now it's always connected to data... anyone know why it's doing this? (maybe i need to start a new thread as i can't find an answer for this email send/receive problem by searching...)
kill the 3G chip that works for me but be sure the the provider has a GSM network
yup, 3g is turned off. these days the usage is more like 5% used up every hour in standby with email checked every 30 minutes. i guess that's acceptable...
Well I am mildly disappointed at the battery life of this phone. With full "phone curiosity" mode turned on I am getting maybe 3/4 of a day worth of charge. As I get more familiar with the phone and some of the novelty wears off, I am hoping to get maybe 2 days? Anybody at that point yet to comment?

yes, the battery is very inconsistant. sometimes it lasts over a day sometimes not even a 1/2 day. There are several forums that have posts about this. I am not sure whether its a set of dud batteries or something else.
had mine for 2+ weeks now, and my battery life is consistent, to where it really depends on my usage. 2-3 hours of talk time, Activesync constantly running with my Exchange server, i will usually get around 16-18 hours.
Now, granted, during the day, i will run various applications during the day, such as a Twitter client, browser, facebook, etc etc etc, and no huge variances in battery life
I agree, very inconsistant for me as well. Seems like most times is about 12-16 hours.
I can usually get away with a charge every 2 days with moderate talk time, push email, RSSHub updating every hour, facebook integration with contacts, weather, etc, etc.
One thing you guys might want to try if you haven't already - hook up the Wi-Fi. I previously had a Motorola Q with comparable services running and it would barely make it through the day. I honestly think the lack of Wi-Fi was its demise because I live in a stone house and get very poor reception.
So anyway, give the Wi-Fi a try and see if that works.
the choice is features or battery life. the nicer a phone, the lower the battery life. the lesser the phone, the better the battery life. a car charger should resolve most peoples battery issues with any phone.
or in a terrible case, call verizon say your battery is awful. they will send you one complimentary battery. now you have two, for free! keep one fully charged and change them out as needed.
My battery life is just fine... long full days @ work with constant txting, calls, vibrate on, data, etc... I did install cabs to stop push internet and reduce RAM consumption but nothing else.
I truly love this phone. It is the absolute best I have ever had.
I don't know, sometime I found Imagio drains more than it should be (My ram is around 48% free all the time with the help of HTC Ram clean). Somewhere near 100% (fully charged), it can fast down to 96 or 97 and sometime I saw figure jump continiously from 92 then 91 then 90.

Here is the "push internet" cab:
http://forum.xda-developers.com/showthread.php?t=532948
I installed it, took me to 48% on reboot but the phone quickly jumped to 80% again in no time. The only thing I really keep open is Google Maps.
I've turned of automatic weather updates, rss hub only updates every 8 hrs, etc... If I don't leave any data hogging apps open in the background, I can get through an entire day with moderate use.
I called Customer Service today. The guy told me that because I have an Exchange Account setup that 6 hours on a battery falls within the specs.
Maybe off topic a bit, but does anyone else have a problem with their phones not storing "Last Full charge" info?
Hi all, I just got my HTC Pure over the weekend and I had a question from those with more experiecne.
First I know (or I think) that the battery life will improve over the next week or so as the battery gets used and charged. Today however was an issue. The phone came off the charger this morning at 100% and then went to work. While at work there is absolutely no signal in the building. (never has been) The only time it was on the network was a 1 hour lunch, and then light internet use for approx 25 minutes this evening. That is all, no calls, nothing, and it had 19% battery left in only 12 hours off the charger.
Again, I am sure that it will improve, but the question is ... does being off the network (GSM) drain the battery faster? Does the phone use a lot of charge "searching" for signal?
I am sure that there are a lot of things that I could do to extend battery life, as a work around (no bluetooth, plug it in to the USB on the computer at work, turn off 3g etc) but I was just curious if someone in the know on how the network and battery use go together if the dead zone is the biggest problem.
Thanks
Not exactly scientific results, but before att put decent coverage in my neighborhood, the battery seemed to drain a lot faster. I guess turning it off would help, but down to 19% that quick just seems ridiculous

Funny enough it is my wifes first smart phone. I was just looking at it to change some things to better suit her needs. When I opened the task manager I discovered that a) the programs would only minimize when the X button was pushed, not close and b) windows Live messenger was loaded. I would guess that even though she was not signed in on live messenger it could have killed the battery. Gonna make a couple of tweaks to ensure that it does not fire up again, and see what it looks like tomorrow.
So today was better, but she seems to have had intermittent service. Her media net indicates that it was connected all afternoon. She burned through 40% battery in the AM and only 18% in the afternoon.
I would imagine that the location services for the weather on the sense home screen as well as possibly push email running out of control searching for the signal. I will turn things off 1 at a time until I find out what is driving the battery loss.
Is there any software to monitor battery use and what was using the battery? There is in android.
O.k. continue to have issues with this phone.
Tested last night. Charged to 100% and then light use. Approx 10% down after 3 hours.
Set commmanagerpro to turn off the data and phone radio during the hours my wife is at work. She called today and the screen is showing that the phone radio is off, but it has lost 90% in less than 4 hours. She also said it is hot.
Maybe her purse is somehow turning the screen on? Would the screen being on without any radios cause the phone to plow through battery?
I am gonna try a battery monitoring app and see if it will tell me anything. Its freekin weird.
What radio version are you running?
You may want to consider flashing to a different Radio ROM.
try to see if there are any TSR, residente program, active, maybe be the the problem...
as far as radio versions the 4.49.25.91, for my exprience run far...
you can try to swcht to other radio version...
I am using the AT&T stock radio. I flashed to the energy ROM, but the battery issue is so extreme that I doubt that the radio or the ROM are the driving factor.
She does have 3 magnets in her purse. 2 magnetic catches on her side pockets and 1 on her wallet. While I could not reproduce the device turning on by itself from the magnets, that does not mean that it is not.
The other thing is that there was some warning on the screen about the GPS signal. I imagine that is a side effect of turning off the radios, but maybe not. Is the GPS always on normally? Would a GPS pop up cause the screen to stay on for possibly 3 hours.
This afternoons test will be having her leave her phone in her jacket pocket rather than her purse. We will see how it goes.

I will look at that radio. I doubt its a program since I had no problems with it at home last night. It has to be environmental. My money is on the purse, but we will see. I'll post later and let you know what we came up with.
There was a few days ago where she lost 60% of her battery in the morning but only 12% after lunch, so that convinces me that it should be something that we can identify and work around.
Energy's ROM may have included the radio.
I had horrible luck with .91 and flashed back to .17.
Symptoms of a bad radio are rapid battery drain and device heating up.
Also, if the device heats up, it will no longer charge until the battery cools down.
If you have AGPS enabled, that was likely your error message when you turned off the radio.
A couple of pointers;
Make sure you monitor which programs are running as you may just be minimizing instead of closing.
Check your power settings and make sure to turn off screen after X minutes
make sure all updates (weather, e-mail, stocks, etc) are set to every hour.

Thank you for your advise. The biggest area of opportunity from your list for me is the Radio I think.
The rapid discharge of the battery due to a bad flash, would that be location specific? The rapid drain only seems to happen in a spot where she has no signal (thus the reason I programed it to turn off the radio in those hours)
The running program should no be an issue. To prevent that, as a matter of standard setup for my phones, they have a small script that soft resets them every morning a 4am, so that they are fresh and clean for the start of the day.
As for updates, I have adjusted everything that I can, and some did not have any effect (mostly because the radio was off, can't save much more than that).
I do leave the bluetooth on all day. That should not be draining the battery in 3.5 hours though. I have read a lot of the battery life threads and many of the ideas would cripple the phone, and I am not going there. Sure maybe I don't need weather updated every 30 minutes, but I want me email when it comes in, not once every few hours. I also don't want to have to push 20 buttons each time I want to make the internet work. Its this kind of usability that sells iPhones... I hate them, but they really do just work... and my wife wants a phone that you don't need to be an expert to use.

Do you know how to view your radio version? Its listed on the bottom of your phone when you reset, the 3 numbers that display, R is the radio version.
You can go to the radio thread and flash another version, just keep testing different versions until you get one that works well. Radio ROMs will not overwrite your data.
Radio's are definitely location specific in regards to region and carrier.
Borderline coverage is a major battery killer, but you're disabling the radio, which should resolve that issue...
G-Profile is a nice app that allows you to set what type of connection and when.

Mine didn't and I used the May 1st update. Still Stock.
If no signal is happening in the building, I would think it's the various things continuously trying to run, like Email, GPS etc. Constant failed attempts to update your phone's apps would definitely drag the battery down in a hurry. I have my email set to 3 hrs. updates along with weather updates. Nothing I do is so important at this point in my life that faster than 3 hr. responses are required. I also don't use things like Tweeter and FaceBook so those aren't constantly eating my battery. I get about 1.5 to 2.0 days from my battery currently.
Here is the current (no pun intended) testing results...
This AM 3.5 hours used 100% of the battery (in the purse)
This PM 4 hours used 21% of the battery (in the jacket pocket)
Gonna try to leave the phone outside of the purse all day friday and see what the results are. Then see how it works around the house on saturday, in a standard limited use type scenerio. Then Sunday put it into the purse and see if it becomes an issue again.
If all of this works out that the purse it the problem, then I will start tweaking it out, and changing radio's etc to get the max I can out of the battery.

So today we left it out of the purse. Here is what we got...
On the table next to the computer, so confirmed that the screen is NOT activating at all. Phone radio off, data off.
AM... used 40% in 4 hours.
Better, but still not good. Gonna try to ensure that the email is set for longer, currently it is set for 10 minutes, and then try to turn off a-gps and the regular gps and make sure that those things are not killing the battery. Then flash a new radio. We'll see how that works next week.
First, test it and watch it over normal, with signal, average 4 hours at home this weekend. I think it will do great... meaning that it is the purse, or the environment that is causing the problem.
I don't know if anyone is following my personal drama, but maybe it will come up in a search some day and help someone.
Here is the saturday update.
Took the phone off charge at 2am and looked at it at 11 am this morning. Used only 2% in those 9 hours. So it is definitely NOT a defective device, or battery. (it actually charges up in only a couple of hours)
So looking into the profile schedule manager that I installed, turns out it has not been running. So the whole purse/no purse thing may be horse hockey still. Monday I will be setting it manually to airplane mode to verify that it holds a charge, then finding a new program to do the scheduling. (looking into phonealarm)
If the radio was on, at full power searching for a signal, it would only last approx 4 - 5 hours at best. So it makes sense that this is what is happening.
Anyone notice a change in their battery life in the past few days? My girlfriend and I both are going through our batteries in just over half a day with no use. It's like the phone isn't sleeping. Looking at battery use Display is using all of the battery. I'm running CM7.0.3 and she's on stock. Looking at mine right now the phone has been on battery for 1 hour 34 minutes, and Display is taking 57% of the battery and I'm down to 84% battery.
Yes! I've had my N1 since January 2010. I stayed stock until recently when I installed CM 7.1 RC1 shortly after it was released. Battery life had always been great, both stock and under CM7, especially with SS4N1. Then, a few days ago it just fell off a cliff. I now get only about 7-8 hours, even with little to no usage. Before I'd barely lose anything if the phone wasn't being used (a percent every couple hours).
Now the Nexus One Battery Calibrator application shows a drain of ~200 mA or more constantly.
I've been tearing my hair out for the last few days, uninstalling apps right and left, trying in vain to figure out what's causing this. I even considered a full wipe and reinstall of CM 7, thinking that some system setting somewhere had gotten horked.
I've always had WiFi set to never sleep, since I'm usually either at work or home. I've also had preferred network type (*#*#4636#*#* -> Phone Info) set to "GSM auto (PRL)" for months.
I've not made any other changes I can think of that would've had such a drastic impact on power consumption. I didn't track all the app updates that happened around the time it started, so I suppose it could be one of those. But I've uninstalled just about everything and it's still happening.
I have the same issue! Just in the past week or so. I have about 50% battery then a hour or so later it's dead! I was going to get a new battery today but maybe it's a CM7 issue. I use the nightly as soon as they hit the mirror.
An update on this... There may be a big issue going on with T-Mobile or some recent update:
http://www.tmonews.com/2011/07/t-mobile-g2-users-suddenly-suffering-from-huge-battery-loss/
Looks like other users on different phones have the same issue!
Thanks for that article, Lost Dog. Makes me feel a bit better. At least I know I'm not just going nuts.
My phone still has increased battery drain even if I put it in airplane mode though. It helps, but it's still much faster than before. This makes me really puzzled as to what the cause could be. How could the cell network still be causing increased drain if the phone's completely disconnected from it? Some sort of configuration information it received that persists even after the cell radio is turned off? EDIT: I may be wrong on this one, see below.
Last night I tried a complete wipe (using Temasek's full format "Format-signed.zip" first), and re-installed CM7.1 RC1 completely fresh. I installed only the minimal Google applications and a couple crucial tools (my password safe app). However, I'm still getting the same quick battery drain today.
I hope we (or T-Moblie) can figure out how to fix this. It really cripples my phone as a useful tool to have such short life!
EDIT: I'm going to try a workaround I've seen mentioned in comments on the TMoNews and Phandroid articles about this: limiting the cellular connection to 2G/EDGE only. It seems to have made a significant difference so far. I may have been incorrect then about airplane mode not having an impact. I'd only been checking current drain with the N1 Battery Calibrator app, and never left it in airplane mode for long. Anyway, I'll post back later this afternoon with results.
Ok, so switching to 2G-only for the cellular connection seems to have made a HUGE difference. The drain rate seems to be back at around what I'd expect. Everything else I left exactly the same (WiFi on, GPS enabled, same applications, etc.)
So, I'm starting to suspect something may be up with T-Mobile's 3G/3G+ service in some areas that's preventing phones from idling properly.
Anyone else want to give it a try?
Interesting, I'll switch over to 2G only and see how that affects my phone.
I've gone as far as wiping everything and that didn't help so if it really is a t-mobile issue then that would shed some light on the situation.
I see the same trend when switching to 2G only. Very steep power usage with 3G then a dramatic decrease in the discharge slope in 2G.
T-Mobile has an issue. The trick will be getting someone there to listen.
Sent from my Nexus One using XDA App
Here is my screenshot. You can clearly see when I turned on 3G. Dramatic difference. Looking on the T-Mobile forum there are many people seeing the same issue but there's mostly finger pointing and speculation as to the cause.

I also got the same rapid battery drain since last Wednesday. At that time, I thought there may be a hardware/battery issue for my nexus one. To test this, I switched my rom from CM7 back to GB stock. After a few updates for the GB stock and used it for a day, same battery drain happened. So, I changed to use another backup battery yesterday. It did not help also. I thought it may be a real hardware issue.
Then, I found this thread and research a bit in the web. I found out it could be either caused by tmobile or google map updates. I first uninstall google map and reinstall the new version right from the market again. I also switch off 3G as well. No rapid battery drain for the entire day. The battery runs normally. When I came back home today, I turned on 3G, let it for a couple of hours, checked a couple of emails and received a 20min phone call. Everything seems to work fine. No noticeable rapid battery drain was observed. My conclusion so far is: this is caused by google map 5.8 update.
Try to uninstall it and reinstall the google map from the market to see if it helps.
Good luck.

Well, I'm willing to give it a try, but I'm skeptical. If it were the Maps 5.8 application that was preventing the phone from idling correctly, or transmitting tons of data, wouldn't we expect it to happen regardless of whether the phone was using the 2G or 3G radio connection? Sure, there might be a slight difference in the drain rate, but we'd still expect to see it in both cases. And yet the accelerated drain is alleviated completely by using only 2G. I have the Maps 5.8 application and can fix the problem by using 2G only. That indicates to me it's not an issue with the application.
I'll try uninstalling Maps tomorrow (I'm using CyanogenMod, so it's possible to remove it completely). Then I'll put the phone back on 3G and report back on what happens.
I've been experiencing similar battery issues the past week or so too. It looks like turning on 2G only seems to fix it, but what I don't get is why I'm still getting horrible battery life?
I have tasker auto turn off my 3G all together whenever my screen is turned off, and yet I leave my phone on my desk untouched all day and I end up at 40% when I get off work.
Wouldn't turning off 3G via Tasker be the same (or close to it) as turning on 2G only in the settings?
Hope t-mobile gets this worked out pretty soon!!
Glad I saw this thread. My wife and I both have N1s and have each been noticing unusually fast battery drain just in the last 3-4 days.
Last night I charged both phones to the same percentage, turned off 3G on hers and let them both sleep for a while. The phones are configured pretty similarly (stock, latest Maps installed, similar push settings etc). After about an hour and a half, my phone had lost 11% of its charge and hers had only lost 2%. That's enough of a delta for me to point to the 3G usage as the culprit. I guess I will be leaving my phone on 2G when I'm not using it if I am going to be away from a charger for a while.
It's NOT the Google Maps update.
Well, I did my experiment yesterday to rule out the Google Maps 5.8 update as the cause of this issue.
I'm running CyanogenMod so it's possible for me to uninstall Google Maps completely, not just the updates. I did so on Saturday night. Still set to 2G only, I removed my phone from the charger Sunday morning. A few hours later I enabled 3G. Later that afternoon I turned 3G off again.
I think the screenshot speaks for itself. Again, this is without Google Maps installed at all.
I asked around this weekend, and my friend's wife (also here in Portland, OR) is experiencing the same issue on her G1 on T-Mobile. Reading online I've heard about the problem affecting the MyTouch 3G, the G2, and many here with the Nexus One. The common elements seem to be: T-Mobile 3G service, particular models of phones, and some particular geographic areas.
Bottom line (IMHO): T-Mobile has a problem with the configuration of their 3G service in some areas, and it's preventing many phones from being able to idle/sleep properly, resulting in huge battery drain.
Here's mine, I posted this several days ago in the TMONEWS thread.

That's interesting. Even locking the phone to 2G/EDGE didn't have an impact? (not a Nexus One there it appears, what model?)
How did you go about disabling the 3G connection? I'm not sure if there are multiple ways to do it, but I used:
Settings -> Wireless Networks -> Mobile Networks -> Use only 2G networks
Really strange that even pulling the SIM didn't seem to make a difference. Or maybe that's not the same as turning off the cell radio entirely? Perhaps the issue is lower-level, like the radio constantly polling the tower or something even in the absence of being able to successfully register on the network for active use.
Does enabling airplane mode fix the drain issue for you?

This is a G2.
2G has been much better than 3g, but still probably only 3/4 of my former battery life, optimistically. I checked "Use 2g networks only", same as everyone else. The graph above is a little misleading, since I really saw better battery life, that initial flat and quick drop actually averages out to "decent", rather than "horrific.
At the "Pulled SIM and SD card" mark I re-enabled 3g, so the drain afterwards is still 3g related.
Pulling the SIM doesn't disconnect it from the radio tower, you can still make emergency calls/etc. so it has to maintain a connection I suppose.
Twice I hard-reset the phone, pulled out SD and SIM, and still had huge huge battery drain. Powertutor said IDLE draw was 1437mw on average, no SIM, no WIFI, just sitting there on my desk.
In Airplane mode it'll last for days...

I'm not familiar with Tasker. However, maybe it's just disabling cellular data use, not actually disabling the 3G radio? From what we've seen it appears the problem is very low-level, perhaps something to do with basic communication/negotiation between the cell radio in the phone and the towers, as there's no indication of particular application activity or significant data transmission that the Android OS is aware of.
In the T-Mobile support thread there are reports that T-Mobile is now acknowledging there's an issue with changes to their HSPA+ network in some areas.
I've had 3G off all day and my battery life is back to normal. I'm at 87% after at least 6 hours on battery. Yesterday I was down to less than 50% by this time. Luckily, I am able to be on Wifi at work so I don't have to deal with EDGE speeds, which make the Baby Jesus cry.
deliamber, you probably noticed this already but I'm also in the Portland market. It's gotta be a network issue.
I'm having the same issue on my N1 (I'm around the Portland area myself)
I did everything as well, 2g is the only thing that saves me..
Can't wait for a fix!
