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... :!:
yo homies
just wondering what sort of batterylife are you getting out of your tytns.
post your times like this
wifi--
media playback--
phone--
GPRS--
anything else you care to mention--
cheers Ganon
firstly bought my 838pro (dopod variant) less than a week ago, so have not gone through everything yet
wifi - yet to try
media playback - little
phone - 2hr+ per day
GPRS - yet to use (did play with the videophony a few days back)
Battery was recharged about 3 days ago, so its ~3days I guess...
One thing to take note is the battery indicator is bit querky, the level is scaled on a 10% rate, eg 100%->90%->80% etc
Battery Seem to last for a bit m ore than a day depending on usage.
I believe that it has the stardard/average PPC phone battery power longetivity but the battery reports every 10% instead of 1% is inacceptable...
Battery Indicator
Does anyone know how modify the battery indicator to run at 1% intervals?
I cannot find a solution to this yet. Hopefully some of the experts will...
I dont get why the fact that the battery goes down in
10% leaps instead of 1% bothers people so much. It does not make the thing less accurate,
perhaps it makes it even more accurate since depending on use one percent might
go a lot faster then another.
I'am quite a heavy user, so I recharge daily for few hours, when
the phone is connected to my comp.
I understand. As a heavy PDA Phone user. The TyTN battery seems to last for quite a long time. But the increment of 10% is too big for a battery meter.
Just like a thermometer, 2~3 degree celcius changes are not very significant for what we feel. But that doesnt mean it shouldnt show every 1 degree
For the car fuel indicator, no one would want it to pop from 10% to 0% all in a sudden. Altho we all know that 10% means low on fuel.
The resolution of 10% is too big IMO for this application UNLESS there is a significant reason for it to be 10% like it will drain ALOT of battery if it is being reported every 1 or 2%.
Hi
My XDA trion makes me sad.
The first time all works fine, but now the charging end at 90% and after 1 day the battery-tool says "low of battery"!
I tried a softreset, but the problem dont disappeared.
Can you help me?
EnzephaloN
I read in some review that it can play MP3s for 8 hours? Has anyone tried how long they can play MP3s for?
I have the same problem as EnzephaloN.
After charging my Dopod 838 pro to full charge in the afternoon. The following day, when i wake up, it is down to 20%!!
Has anyone else experienced the same problem?
I barely used the phone during this period and I have turned off Wi-Fi and Bluetooth.

mine's even worse, charge overnight, and after taking of charge at 9am it's dead by 4pm after just a few calls and the rest of the time on standby, noticed that the machine stays slightly warm all the time. the few times that it has held a charge it is cool to the touch, even when using it
switch to gsm band.......and use UMTS band only if necesary
am using only gsm band, but still the machine only lasts 4-5 hours on a charge. Stays warm the whole time

Mine only gets warm with intense browsing, streaming media, or wi-fi use more than 30min or so.
Also when i have UMTS/3G off mine will last all day. but with it on, it'll last a little more than half a day.
if it stays warm, i suspect you have some background task running all the time or your power saving has been turned off, why don't you do a full backup, then hard reset and test again? mine works more than a day with UMTS turned off and less than a day with it on.
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.
I've had my Touch HD a couple of weeks now and I absolutely love it. My primary use of it is as a pocket pc and the phone comes in as a handy extra.
However, I seem to be getting battery usage problems that other people have been experiencing and I have a few questions.
I'm using Powerguard and AEButton Plus to show me my power usage. Both report about 85mA when no applications are running and no data connections are in use. I have my backlight turned down pretty low, activesync closed down and I don't use AEButton Plus to turn WiFi on and off as I don't use WiFi. Is 85mA about right? I've no idea what it is while it's in standby.
Yesterday I used my Touch HD a lot, playing about with GPS, surfing etc and by the end of the day I had over 60% charge left. Today, after a full charge overnight from the mains, I have used my Touch HD very much less but I'm already down to 56%. Powerguard still reports about 85mA when my pocket pc is idle but I've been able to watch the percentage power drop every minute or so. Then it would speed up and at other times slow down again.
Why would the battery drain so much faster today with the same or less power being drawn? AEButton Plus reports an uptime of only 1.5 hours yet almost half the battery is used up.
The battery is only a couple of weeks old. I cycled it about three times when I got it, ie letting it run down completely and then charging it back fully. I'm not charging it in the cradle but directly off the mains overnight. Has the battery lost it's calibration so quickly?
If I have applications or devices drawing more power, shouldn't I see that in a higher level current usage. When I have GPS on it goes up to about 300mA so I'm assuming that at 85mA there is nothing else running that shouldn't be running.
I have spent a lot of time installing all the applications etc onto my Touch HD and so only want to hard reset as a very last resort. I really need to be able to use my pocket pc and get on with my life now, but I can't if I'm worrying about whether it will last through a phone call.
I've got a spare battery on order, but I would really like find out why my battery is draining so much more quickly now.
Please help. I love my Touch HD. It does everything that I want and it's gorgeous, but I need it's battery to last at least a day.
Thanks,
Teresa
Sorry, I should also add that I'm using the stock V1.56 ROM.
Teresa
This is getting weird now. I've now started to use my Touch HD more. I made a 20 minute phone call, ran TomTom for a few minutes and now I've had google maps running with GPS for about half an hour and I've only lost a few percent. My power is at 50%. It seems that the more power I draw from the battery, the more slowly it goes down.
Do I need to cycle my battery again? I'm worried about doing this too often as it stresses the battery and shortens it's life.
Teresa
batt and batt % are not a reliable thing
you can't really rely very much on it
and it's never linearly
I know the battery usage isn't linear and it tends to speed up as more power is used. However, the pocket pc uses the value to decide when to shut down. My Touch HD has just run out of power with an uptime of only 3 hours and 50 minutes and it was fully charged only sixteen hours ago. This does not leave me confident in being able to use it for a whole day.
What can I do to improve the battery life? I have an HP iPAQ hx4700 with a four year old battery in it that still lasts ages and ages. I don't think I'll get anywhere near as long a life from my Touch HD battery. I only need it to last a day between charges with an uptime of at least six hours or more. As soon as the capacity of this battery starts to degrade, it will be useless as it's only just useful now.
Teresa
get dotfreds taskmanager too see what processesvare are running inthe background.
use advanced config to enable the power saving features
Thanks for the suggestions. I've already spent ages searching these forums so I have been using dotfreds taskmanager and all I see is idle running at about 80% because the other 20% is being used by the task manager. AEButton plus only uses about .1% every few seconds. Is 85mA usage high for idle?
I'll try advanced config to turn on the powersaving features.
I need my pocket pc and phone all day to day as I'm out and won't be able to recharge it after this morning. I just hope it lasts.
Teresa
Hi,
In this forum I saw many tips how to reduce the battery usage. You could search those.
For example turn off 'Receive all incoming beams' in Setting/Connections/Beam.
You also can flash one of the cooked ROMs that present here. I use onkolog's Lite ROM and battery usage is very low (10-20% per day with moderate usage).
Thanks, but turning off incoming beams is one of the first things I did. I think I've followed most of the tips I've found and I've even managed to stop that pesky activesync from keeping on coming back.
I'm not running Powerguard today and I'll just use my Touch HD normally and see how it goes.
I don't want to flash a cooked rom just yet as I've never done that before, but I'll try that eventually if my battery usage continues to be so poor. I have a lot of applications installed on my Touch HD, so building it takes a very long time. I use it for everything, from shopping lists, access databases, reading ebooks, playing games, satnav to plain old diary. These are all applications that ran quite happily on my old pocket pc without undue battery usage. The only main difference on my Touch HD is that I'm using TFDetacher so that I can still have my old Today screen as well as Touch Flo.
Hi, only if you run out of solutions, you could look at this thread for an extra battery (I've not tried it myself but it increases your battery life by 200%)
http://forum.xda-developers.com/showthread.php?t=529673
Thanks for that, smeddy. This looks like a really interesting product. I will look out for what people say about it.
My battery seems to be much better so far today. I'm still on 100% with an uptime of 25 minutes since I charged it up over four hours ago.
85mA while idling is reasonable if you have backlight level at >50%.
68mA is the lowest I've seen at minimal backlight level on my HD.
Hey TeresaTT,
Something I can tell you with a high degree of confidence is that you really cant trust the battery gauge on the HD that much, either under idle conditions or with higher battery loading. And just try doing a reset and I bet that it'll will come up on a different % value after you reboot!
Another thing is that battery consumption is quite dependant on not only how you configure various functions of your phone but also what ROM you use. My present ROM seems to be noticeable more battery effecient than many of the ROMs I tried before, and most especially the stock ROM that came with the phone, and the stock ROM I initially upgraded to.
EDIT:
Cant comment on the battery current consumptions as I've never felt the need to measure them.
LoopyLoo
Thanks for the info. My Touch HD draws 85mA with the backlight set pretty low, just one point off the lowest. Therefore it seems that the usage is pretty high. I'll have to look at other roms and try one or two, although I need to wait until I've got some more time free. I've already spent hours and hours on my Touch HD, but I do love it. It's a huge upgrade from my old HP iPAQ hx700.
Before my battery would last about a day but after flashing to my current custom ROM now lasts 2 to 3 days with moderate usage. If left on standy idle the % doesn't seem to go down. Probably last a week doing nothing...
I believe the official ROM I had before was buggy with power management i.e. even when on standby with screen off, sometimes it may not cut off power sucking features like WIFI, gprs/hsdpa, bluetooth etc.
Thanks for that ez2remember. It looks like my Touch HD is behaving normally with a stock ROM. I've had a quick look at the ROM forum and it almost looks like a foreign language. Even the dummies guide is a bit foreign with HSPL, USPL etc. Then I have to pick which ROM to use and hope it's stable and all my applocations work. I can see that this is going to take quite a bit of time for me to research. I'm fairly technical so I'll get there in the end.
Yes I agree flashing can seem a bit daunting. This is my first real WM device. I've played with one briefly before so found the conversion slightly complicated. I came from s60 devices. Dummies and step-by-step guides on s60 were really easy to follow. I just think WM users are far more technical so instructions seems more complicated than it actually is.
It's just a matter of getting the latest HSPL onto your device (one time affair) then you can flash as many custom ROMs as you want.
You can use nue ClockSpeed 1.3 to manage the clock of the processor.

Also, Pocket Shield will switch off screen wile talking, and a lot of functions I don't use.
My garmin gps shut down few days ago and i had to use garmin in my HD for around 1.5hrs....
I think i lost only around 20-30% charge.
My battery lasts atleast 2 days with wifi on all the time ( wifi auto off in standby mode.)
I do make few calls and sms
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% 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!

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.

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.
