Short battery life on HTC, is this what you are seeing?

I've read a few posts on HTC Wizard battery life and I'm trying to quantify what I'm seeing (which is hard given varying conditions under which the device can be used and what features are active but I'll attempt that here). I'd really like to hear what other pepole are experiencing under similar conditoins.
I’m getting about two days worth of battery life before the unit is warning that the device needs to be recharged. Here’s what I’ve done with it over the past 2 days:
· 47 minutes time spent using the phone. I get the full 4 signal bars just about everywhere I go, including and the office and at home. I have not used the speakerphone at all.
· About 1 hour of PDA use
· Bluetooth and WiFi have been off. There was no GPRS use during this time.
· The screen brightness is set to the lowest level possible, one setting above the backlight being completely off.
· When on battery power, the backlight automatically shuts itself off after 30 seconds and the device turns itself off completely after one minute.
· I’m running Windows Mobile 5.0
The battery currently reads 18% after 2 days.
Is this in line with what other people are seeing?

I used to drain my wizard to about 50-60% in one day (from morning to evening), when I still let it go to standby, so that seems about right. It goes down a bit faster now because I always leave it on (just let the backlight go off of course) so agile messenger will stay online...
I'm pretty sure this battery life is pretty good for a pda phone though, you can't compare this to a regular phone.
I always connect it to the charger at night so it's no problem for me, and I bring a very small usb cable (like 15 cm) when I don't sleep at home. Usually there's an opportunity to connect the wizard to a computer somewhere so it'll charge, the computer doesn't need to recognize the wizard for that.

I need to charge my Wizard evry night, if it's friday with party etc alot of calls i need to have my samsung d600 with me becuase the qtek goes empty around 23.oo :/

Just done a typical "intensive" day, and I'm really pleased of that thing. Here's what I've done:
~50 min on the phone
~2h30 MP3 playing with TCPMP, LCD off of course
~30min e-mail and internet through wireless
obviously a bit more PDA use, cause uptime meter says 4h39 :wink:
I still have 54% battery at the moment.
Useful to mention, forgot to turn off wireless after browsing, so it stayed on for like 1hr with device off, and that still drains juice.
Backlight is set at the middle.
Once again, my BA would be dead by now. I had ~4h PDA use at standard clock settings, 2hr with wireless on. The Wizard just doubles both these figures. I definitely understand why they've dropped that guzzling XScale... wish there could be an optimised version of TCPMP soon though, video playback is the only thing where i see a real difference in speed, haven't managed to have a video playing smooth without hangups yet.
Skype doesn't run well, but it didn't either with the BA without overclocking it at the maximum it would hold, giving a stunning 1h30 battery life (with wireless on obviously). The device was really hot while doing this, and the standard charger would not give enough current even to power the device, battery was still going down when connected. Had to use a 2A Axim adapter to charge while skyping :shock:
So definitively a GREAT improvement.

I used my MDA Vario the other day and it went down to 18% in approx 4 1/2 hours.
Screen was at max brightness and on for the whole time,
Tom Tom running.
Bluetooth on
About what I'd expect. I don't think my Treo 650 would be much better in similar circumstances.

I just updated the other thread about the battery that up till now its been fine but two days ago the dreaded issue started with me too
I've just lost 20% in 3 hours without doing anything (its been off since)

AKU2 rom gives a definite improvement, I can have 85% left after a day of normal use.

Which AKU2 rom. T mobile hasn't released one for my phone yet, to my knowledge.

The qtek rom, many vario users are using this rom out of frustration for t-mobile not releasing theirs.

Hey if you upgrade the ROM you should run some tests before installing any applications. It would be a definite advantage to make sure it's not some buggy app that's causing your battery drain.

agreed... I think that is my issue too that it could be a memory leak somewhere in one of the programs
can only put it down to registrywizard, uptime, or resco, the latter i doubt very much though

I upgraded my vario to the newest imate rom and would totally recommend doing so.. my battery life is about double what it used to be now (may have installed something dodgy that was draining it though)
Its also much faster in operation and seems to be a lot more stable too (I suffered a lot from the random reboot problem previously)

what did you upgrade from?
and what rom version are you running? the ones on the ftp for kjam are numbered a bit strange and can be confusing

The numbers are confusing for me as a noob to WM5/wizard.
What is the difference between the Qtek & the Imate roms?

WiFi doesn't drain battery when the device is turned off, cause the WiFi module will also be turned off automatically - just test it: leave WiFi on and press the power button - after a few hours look at the effect on the battery... :wink:
I usually recharge my Vario every 3-4 days. Although I don't use WiFi and I also don't make many long calls I usually use GPRS always on to receive my mails. I also use BT quite often to listen to music over my A2DP headset - maybe one hour per day on average...
So there must be something wrong with the devices of some of the people posting here... :!:

Average Battery Life on T-mobile Wing

I was just wondering what is the average time of battery life on your wing..mines is currently about 10 hours idle but while im using it that goes down to about 5 or 4 i just wanted to know what is the average before i call t-mobile and ask for a new battery.

A few of us here have been having problems with the battery actually. When I first got the phone, I left it clean and stock. I would do a lot of texting, make a couple phone calls, and play a few games here and there. From 7am to 1am, I would go from 100% to about 54% (18 hours of usage). Now, if I leave my phone idle for 2 hours, my battery drops down from 100% to 80%... I can't even go a full day without needing to charge the darn thing. 200 hour idle time my arse!
But personally, I don't think it's a problem with the battery... The phone is doing something in the background which is causing a massive battery drain. Right now, I'm testing my phone to see if I still suffer the same drain while in flight mode. I'll post the results HERE in about an hour from now.

The longest the battery can last is 1 week...
On a full charge, you can talk for 5 hours...
the more features you use, the more power it'll consume.. if you do a lot of internet browsing, I believe I saw GPRS Data connections use more power then WiFi.. so use wifi when available ...
also, be sure to regularly check your phone's task manager before setting it aside for long periods of time... sometimes it can be hard to notice the camera, text/mms, calender, Internet Explorer, Windows Media Player, are all running in the background while you're at the home screen...
My wing usually lasts me from unplug at 8am until plugin at midnight... power usage always varies a lot as... as you can tell.. the data connections use a lot of power... and if wifi isn't available, it uses at least 30% more power doing a GPRS Transfer -- based on the initial information i've read about the issue.

I noticed Bluetooth and WiFi taking more battery than GPRS

As long as I plug it in while I am at work to a USB cable, I don't seem to have any battery problems. I use GPRS and SMS constantly.

I spend the whole day on the phone ... between texting and I receive all my work email directly to my phone... so I'm on it various times during the hour... and it seems the battery drain is huge.
all I have done is turn the screen brightness down whenever I'm not using it, and have the dynamic overclocking on, so the processor goes down whenever its not in use ... but I still think the battery drain on the wing is ridiculous.

Well david, overclocking doesnt help
Im clocked at 247mhz, i can make it last about 24 hours using it here and there. calls about once a hour for 5 min or less, texting through the day, and occasional wifi use. at stock clock speeds, it lasted about a day and a half, but it all depends how much you use it

At 1st i thought the battery darin was rediculous as well but when u think about it when u use it the battery goes down about 8 times as fast( depensing on what ur actually doing w/ it.
Now i charge it at night and go to school with fully loaded battery 6AM, i text all the time and when i get home its around 85% 2:30PM, use it occasionally and at the end of the day after at least 3 hours of talk time its on around 30-20% i could last w/o charging it but i charge it overnight to full, with NORMAL use and not talking for about 4 hours per day so far its lasted 4 days for me. could have made it to 6 but i wanted to showoof my new phone to my friend
so battery life is not that bad just depends how much u use it, Also if ur listening to music just turn off the screen and thats a REAL battery saver. also press the power button when on the phone and etc.

Wing Battery Drain
I have improved my Wing battery drain by doing the following...
- Turn off the automatic weather update on the Today Plug-in
- Check my emails manually (do send receive when I am ready to read)
- Suspend device when not in use - need to use device lock app.
- Update ROM to PDA Viet v 14 (thanks to easy instructions from David)
With the new ROM and the device locked - even the accidental press of any of the face buttons (when phone is in pocket) turns the device back on - even though the screen remains locked (due the Device lock app). Is there any way to suspend the device completely so can only be turned on by hitting the power button only? I would still want to receive / answer calls etc. without having to hit the power button....

Go to settings, Lock ... and there is an option to lock all buttons except the power button when device is powered down.

I am trying to fix my sisters Wing (I have a Wizard). I have tried disabling background programs, as well as setting things to be more gentle on power usage, and still she loses battery like crazy. I know the Wizard had some battery drain issues with certain WM6 cooked roms, and a cab fix helped. Does anyone have a cab fix for the Wing? Also, reading in this forum section, it seems that the Wing doesn't always disable background programs. Would you suggest a third party task manager to "pick up the slack" or does it not matter, due to the nature of the winged beast?
I appreciate any suggestions. While I am new to the Herald, I am "old hat" on the Wizard, so I do have a general understanding of how the HTC devices work.
Thank you in advance.

I have read a lot of bad stuff about battery life with every rom except the OME t-mo. I had the PDA viet and battery life was terrible, With the stock rom it is at least 4x longer.

hello ive the same problem with the last 4 wings ive and ever since ive switch from the stock Tmo OS and upgraded to the TouchFlo OS, Ive noticed a huge differnce with the battery life even overclocked
If your will to taking the risk ide say go for it, i jus started messing around with rom and i got say its a big improvment from the original wing which i was ready to throw against a wall!!

I have Touch Flo on my Wing, and if I charge it to capacity I usually only need to do so it every other day so long as I don't play any NES games on it. I keep the wifi off if I'm not using it of course. I have it dynamically stepping the CPU in a range from 100mhz to 234mhz. It really seems to help extend the battery for me, while still giving it the tiny extra kick it needs to run nes and sms games.
My wife has the official wm6 rom on hers, but is also dynamically overclocked as mine is. She needs to charge hers nightly, BUT she also plays solitaire and bubble breaker daily.
Overall it's on par for battery life with my prior motorola phone, which I never used for anything but regular phone calls. With that in mind I'm not necessarily impressed, but am definitely content with it.

I've had HORRIBLE battery life and AWESOME battery life, all within the same week. lol
There was a problem I had at one time, where filesys.exe would take over all the CPU and kill my battery.
Here's what I do, though.
Dynamic overclocking/underclocking
Turn off GPRS when not in use
Disable Push Mail
Turn off WIFI and Bluetooth
Turn the screen brightness down
Turn off the screen altogether, even when on a call, unless you need to see what's on it
There's a few tweaks out there that deal with enabling the power saving features on L2TP and stuff...

First post here-
I've had my wing about a week now and have a question concerning battery usage.
It has always been my understanding that batteries will develop a "memory" if you charge and recharge them under their full charge capacity.
i.e. if you use it down to 60% and then charge it to 100% it will remember that and not use the full original 100% charge. obviously over time not just from a single "half charge" like that.
So since every time you connect it to USB to sync it begins the charging process, won't that wear down the battery and make it develop such a memory?
Is their anyway to connect to to the PC without having it charge?
I have always preferred to have any mobile device drain it's battery to nearly empty before recharging to try and minimize the memory effect.
Thanks

Today's lithium ion batteries do not develop this like older rechargable batteries. You can plug your phone in at any time without worrying about losing battery capacity!

Thank chris30_2001, good to know.
oh and it's ALWAYS lupus

I listen to Streaming Radio with my Wing at work all day. I get approximately 4 hours of listening time before I have to swap out with another fully charged battery.
I use PBar to shut off the screen while listening.

I'm running the touch rom without the actual touch. I can't remember which one it is. I spend at least an hour a day gaming (text twist, random solitaires) on it. I usually hit up the web a few times a day for 10 minutes a shot. I use it as an ebook reader. I send txts constantly. I talk about half an hour a day. All this leaves me with about 30% - 50% of my battery by day's end. Now, if I turn on bluetooth all day it will end up around 18%. Wifi is such an evil power hog I never turn it on, EDGE is fast enough for me. I charge my every night under my pillow (it's my alarm too). Battery life has been the same since I got it about 6 months ago.
Edited to add: I also do some dynamic underclocking for things that don't need a huge amount of power, like my budget program, etc.

[Solved] Battery usage

So im trying to figure out where my battery is draining to... I cannot go a full day on a battery charge and its really annoying at night it jsut dies and plus i cant really do too much on it for fear of battery drainig itself. Is there a way.. i can check to see what might be taking up battery
Wifi off
GPS Off
no 3G in the US
Bluetooth Off
Push Mail off... (though am syncing 3 mail accounts every 2 hours... minimal mail though)
Internet usage 30 minutes (besides, weather stocks)
Phone usage .. about 60 minutes in the day
Gyrator on
General usage.. games, tinkering etc (60 minutes... hey its still relatively new)
Appreciate the input.

Strange..
I've got two mail accounts, talked for 15 minutes with a bluetooth headset (been connected all day).
From 06 in the morning until now at ten in the evening I still have 7 bars on the battery. (three in the TF3D)
Consider doing a hard reset and set up stuff and see if that helps..

After tinkering for a couple of weeks, I hard reset and just put back on what I want. I also used Tweak HD which has a few tweaks to lengthen battery life. It made a big difference to me.
Orinigally it had drained in about 18 hours, afterwards it went slightly over 40 hours.

this is strange - i use my phone alot and it easily lasts 2 days
have you tried replacing it? when i bought my first diamond it was faulty, replaced it and batteyr life changed
also try flashing a stock rom on again and see what happens - less than a day - defo not right!

diamond v hd
had 3 diamonds, battery was lucky to last 10hrs, ate 2680mA battery packs like jaws ate boats!
HD, charge 1 every 2 days.... huge improvement... would love it to last longer, but its a million times better than the diamond and thats all that matters...
HD battery life in conclusion, is great, and i do hammer my phone usage!

I'm seeing similar battery issues as the OP. I barely make it through a 12 hour day on a charge, although I get a lot of e-mail on 2 accounts (one checked every 15 minutes, the other every 2 hours). In an effort to track down battery drain, I downloaded and installed HomeScreen PlusPlus and find that at rest with screen intensity at 60% my HD draws 150 mA, with the screen dimmed at 10% it draws 70 mA, and in standby (blank screen) it's drawing 30 mA. When the data connection is active, it draws between 250-300 mA, and when using the phone with screen on about 400 mA. I figure that with those numbers and a 1350 mA battery, 10-12 hours is all I can expect. If anyone else is monitoring their battery draw, I would appreciate seeing your numbers for comparison.

Oooh this is a good idea...
anyone else done homescreen++ to find battery drainage.. im going to get to it this weekend...

Have the same issue.... I have nothing special installed and for some reason it drains very fast on basic features.....

Same issue here
Recently I've been getting less than 12 hours out of a full charge. I've uninstalled a few things and turned bluetooth and wifi off and today it seems better with about 80% left after 10 hours
Vaguely considering a hard reset if the problem continues...

have fixed certain aspects now using the new version of Tweak HD

For our benefit.. could you please tell us...
1) your version of Tweak HD
2) WHat did you do to improve battery life
Thanks

Progress
So I installed Homescreen++ to be able to monitor my battery utilization... and im averagin 150mA to 350mA with it being closer to 300mA most of the time... no wonder I am getting 10-12 hours of battery life.. and this is with the device not doing anything.. except cehcking mail accounts.. NOTHING else...
I really need help with this.. every night at around 9:00pm.. i am without battery and its driving me nuts...
short of a hard reset... what can I do to monitor what programs or processes are taking up my battery?

I really feel your pain. I must recharge during the day everyday. I've ordered a second battery, but it hasn't arrived yet. I've done all I can do with HD Tweak and Schap's Advanced Config, even turned the screen brightness down further to no avail. I don't want to hard-reset, but I'm going to give that a try this weekend. Before I do, If any of you experiencing good battery life has a few moments and is willing to install HomeScreen ++, please post your numbers to compare to ours (mine are in a previous post). The download link is:
http://www.chi-tai.info/cs_batterystatus_xda_neo_wm5_im_cs.htm#Download
It can easily be uninstalled through "Remove Programs" later.
Thanks in advance for your help; I am so enamored with this amazing device that I can't bear to give it up!

Battery life much better than my Kaisers...
​

Apparently Batti uses a lot of battery (ironically).
I've just replaced it with Ariel battery and will let you know how it goes:
http://forum.xda-developers.com/showthread.php?t=364278

I'm not running Batti.
I have been through an Apache, a Blue Angel, a Hermes and most recently a Kaiser before springing for this amazing Blackstone. All my previous devices made it through at least a full day before requiring a recharge.
My ROM is 1.14.405.3 and Radio is 1.09.25.14

I'm thinking of springing for the HD, I currently have a Hermes. Battery life is a major concern of mine, and on my Hermes I had to purchase a larger battery with the extended back plate.
Does the HD turn off the screen when not in use or is it on all the time? Also how does it do with WiFi on?

Battery\power consumption issue

hi, i am having a bit of a problem, i have searched the forums but could not find much relevant. my X1's battery is really struggling.
On one occasion i managed to get 22 hours out of it, but the average is between 9 and 12. I lock my keypad and turn the backilight off when its in my pocket, i have it set to update rss and e-mails every 4 hours, i downloaded an app that switches the modem connection off after 1 mins idle time, i never use wifi and i haven't even been making any calls, and dont use any apps, ie games ect. i send a few sms, and after 9 hours away from a power supply, my hungry beast is down to 10% battery. i can not work out where my power is going. as i said i have searched the forums, and my phones settings, but can not find anything to help. if there are threads with answers please link me to them, or if you can help, please tell me
1) are there any power management apps that i can download to monitor and control the power usage
2) is there anyway to prevent the modem auto connecting whenever it finds an Edge\Gprs|hsdpa\whatever signal, as i am convinced this is the main culprit. even with rss\email updates switched off, the phone is ever connecting to the network
3) how are people who claim to be getting 24 hours+ with extensive browsing, calling, gps'ing and wi-fi'ing actually achieving this
4) would the rom firmware update help with my problem
(apologies, the question mark key on my laptop has returned to the big keyboard in the sky!)
any help anyone can provide would be much appreciated, as i am afraid to use the awesome features my phone has, for fear it will die.
thanks a lot

Have you got any shell applications runinng (TouchFlo, full SPB)?
Else sounds like your battery is fooked.

Weird
Well, how long have you had it? In my first week I was getting about the same, but now in my second week it's improving with charge/discharge cycles.
I don't use data connections but use Wifi/BT quite a bit and listening to music and it will last a day now.

Trying using just edge and lower your screen brightness to 20-30% when you use it.

I had a similar problem when I updated to the R2 ROM and installed some applications... primarily AEButton plus and S2U2 (although I believe it was AEButton that was the culprit here...), I would get 13 hours or so before the phone went down to 30% from full charge... I uninstalled both programs and then got 84 hours with moderate use (lots of sms, few mb internet and a few calls (about an hours worth)... so I am wondering if you have either of these installed or if its an app that is causing the problem... (I now have AEButton 2.6.6 installed and after 6 hours its only dropped 10% with quite a bit of internet use (mainly edge) and a few sms's)...

I've tried S2U2. And as I've stated in another thread, it is indeed a battery drainer.

That's not true at all. Just activate the energy saving option.
My battery lasts for 5 days now, longer than ever before. Cannot say if it's the effort of S2U2, but it's definitely not draining faster than without it.

EDIT: Just found out I'm running a really old version. Updating

had the phone for about 3 weeks now, tried charging and draining it a few times, still on the vanilla ROM, and i did have one of the interfaces installed (cant remember what it was called, not touch flo though) but i removed it. i hope the battery is not tits, but how can i test. i will try the brightness\edge only thing, so as for my 4 questions, no answers then(question mark)
thanks for the advice!

Guys,
I have installed SPB Phone Plus, Inesoft software and digital clock on my X1, do you mean that it will consume more battery power with these programs installed?
I notice that my X1 now only last a day while before the R2AA upgrade, it can at least last me 2 days.

Mine had the same problem during the first week or so. Now i can leave it 12 hours without charging and if i don't touch it, the battery stays at the same level.

eh, how come u all battery so fast flat 1??
mine can stay for almost 1 day.. listen to music always.. always connected to HSDPA/3G/EDGE/GPRS... listen music through wired, play game little while.. no wifi..
in da morning 7am, full... go skool, listen music whereever i can.. surf net.. then come bak to home at 6.. is got around 4bar of "power" settings ther..

I've also had a problem with my battery. It wouldn't last through the night. I installed a process monitor this morning and I suspect the culprit is S2U2 v1.37. I've just updated it to v1.45 and I'm about to test again.
For those using this version what settings do I need to enable Power Save? Is it just the registry entry or should I be changing something else in the settings?

I had been worried about the battery before I bought my X1 and I ran across a WM 'bug' which could be the problem (I'm sorry, I don't have the source because it was a while ago and I was just browsing before I bought).
It said that when WM runs for the first time it presumes full battery power and so will charge to whatever level the battery is at at the time and no higher.
Some people resolved this by either:
1) Charging when the device is off to increase the maximum charge
2) Hard resetting the device and fully charging before the first switch on.
I have to say, I use 1 hour of video, 15-30 minutes calls, 10-20 texts, 30 min web browsing, email/weather etc updates every 2 hours, 30 minutes 'bumming about' (games, file copying, tweaking) every day and get at least 2 days of use.
Overnight, (ie when not being used and for 8 hours) I have never dropped a bar of power.
I do not run any additional programs in the background, apart from the spb panel.

Well I tested this and I can confirm that v1.45 of S2U2 does indeed save power. My battery was 90% last night and was the same this morning.

the power save in s2u2 is quite annoying isn't it? i had that on and when im listening to music through the media xperience panel, it just goes to lock the device (when the idle time is up) and stop the music. Its annoying as hell.
Plus whenever im watching videos (still with the panel), it just lock the device again.
Thats it, no s2u2 for me. Uninstalled it right after that

i had the same problem until i installed a cooked rom on it....now i get about 3-4 days....i recently tried installing a few different ones and the battery life fell again....but thry installing this

I had a similar problem when I updated to the R2 ROM and installed some applications... primarily AEButton plus and S2U2 (although I believe it was AEButton that was the culprit here...), I would get 13 hours or so before the phone went down to 30% from full charge... I uninstalled both programs and then got 84 hours with moderate use (lots of sms, few mb internet and a few calls (about an hours worth)... so I am wondering if you have either of these installed or if its an app that is causing the problem... (I now have AEButton 2.6.6 installed and after 6 hours its only dropped 10% with quite a bit of internet use (mainly edge) and a few sms's)...

Sorry, what program is S2U2? Where to download?

When I just got my phone back in November last year, my battery kept draining quite fast (empty within about 15 hours). By now even though I still use it as much as back then, the battery easily last twice as long if not thrice as long. I now manage to have it last for more then 2 days.

I notice power drain when I had SPB phone software installed and also after alarm go off in G-Alarm. With the spb phone, i think it's because of the repeating reminders option, didn’t really tested out, just uninstalled and X1 hold battery pretty well.
In the F-Alarm, after alarm went off it, seemed like only display did turned off and the device didn’t really suspended\turned off. And the battery could drop about 10% within a few hours. Soft reset stopped enormous consumption…
That’s my experience for now, hope helps someone..

Battery Drain HD2?

Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.

+1
-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days

we really need extended battery ,hd1 battery was much more better.

Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87

I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.

I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.

try setting Network Selection to Manual

Same here with and without stock ROM.

yeah.. the phone is a battery sucker.... another cons of HD2....

This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.

I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?

maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse

I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy

Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.
