XDA2i battery life

what sorta battery life do you guys get? Mine's about 3-4 hours (less if i use BT and WLAN!)
admitedly i didnt leave it charging for the full 18 odd hours 1st time round, so i bought another battery (needed a spare anyway) and made sure it was charged up 100% correctly...
its giving me exactly the same battlife!
obviously turning it off/standby itll last ages, but its crap when using the PDA!
am i doing something wrong?

join the club (no pun intended)

3-4 hours is especially bad though.. mine will last a day or maybe a day and a half depending on use, but no where near as good as my old xda II

i got 2 hours out of it yesterday night...
i turned on bluetooth and wifi, and watched it die (just left it on the desk n pressed the screen every now and then)
now surely 2 hours cant be right? i'm having to leave it plugged into the pc all day at work AND carry a spare battery!

Mine seems just OK. I took it off the charger last night at around 10pm and by 5.30 this afternoon the battery was down to 59%. That's with several calls made -no wifi - about 30 mins GPRS browsing - but BT was on all the time.
I'm switching BT off until I need it, and seeing if that makes any difference.

Wifi will suck the life out of it, Jim. Have you been through all the usual suspects like beaming etc?
Kevin

wow jim thats really bad.. have you tried discharching it completely, then leaving it on the charger for about 12 hours, and doing that a couple of times? sometimes that improves battery life.
i think i might try the worst case scenario you did and see how long mine lasts
kevin.. that sounds half decent.. especially with BT on the whole time. sounds like you're one of the lucky ones

Battery
I am the sort to cover all bases so please do not get me wrong.
Bro have you configured your Xda IIi backlight and power to go on standby mode yet?

tried it with mine, had bluetooth on (not connected to anything tho), wifi on (not connected to anything, but it was finding wireless networks every 10 secs or so and kept popping up that do you want to connect bubble), recieve incoming beams was ticked, gprs was connected and it was getting used a couple times each hour to sync my email, and i probably received about 4 phone calls and made one or two. my cpu was set to standard (not turbo)
mine lasted for 4 hours at this rate, so a fair bit better than yours.. unless you were actually using bluetooth and/or wireless

its now as low as hours!!!!
even with every power saving thing on possible, i can only push it to 3!!!!
o2 will swap my phone over, will do this on monday/tuesday (just gonna pop into shop) but it means getting the new one unlocked again... grr

wow thats pretty horrible. good luck with the next one

just upgraded to the imate rom (which is always clever before taking somthing back to the shop )
its now giving me 4 hours instead of 2... so it's gone up

i dont think my himalaya last much longer unless i let it go into standby
and lower the brigthness when using batt

4 hrs is not normal either, usually my 2i can last for 8 hrs (not counting stand by of course). yesterday it suddently ran out of battery within 5 hrs and really had me worried for a while. Than I found out it was because I adjusted the backlight brightness to very high. It seems the LCD backlight has a major effort of consuming battery power.
Tricks summed up from other topics:
* Darken your On Barrery backlight brightness (Start-Settings-System-Backlight-Brightness)
* Shorten your On battery backlight remain time (Start-Settings-System-Backlight-Battery Power)
* Set your CPU mode to standard (Start-Settings-System-Power-Processor)
* Close incoming beam monitoring (Start-Settings-Connections-Beam)
* Try you best not to connect any network (Bluetooth, GPRS, WLAN...) :?
* Put less item on your today screen
* Some software has update or refresh service running on background, try to increase their interval:
[list:8501145cfd]- OmegaOne BatteryPack has a default setting of 30 sec update interval, and a network activity monitor. All can be disabled in today item's options.
- Marsware WeatherPanel has a default setting of 30 min update interval
- All alike stuff you can think of ...
* Applications remain in memory when you click "X", shut them down if not using anymore. (Start-Setting-System-Memory-Running Programs)
- Some apps have convenience tool to do this, such as OmegaOne BatteryPack, or O2Plus.

There is a fix due next week, i currently have the beta firmware installed and its increased my battery life by 3 fold.
Wait for the next firmware and all will be sorted

yes!
i hope imate upgrades too

Whereabouts are you, Noodleman? O2 Asia (where I am) is renowned for being the last with things.

rom upgrade! where?!
where can I find a rom update for my XDA?! it doesn't have a specific carrier.... I bought it with english software.

I do not find battery with a better autonomy for the 2020i! Does it exist?
like 1800 mAh or 2000 mAh !!!

Up ...
No idea ??? :?

I believe this is O2 Europe - if it's the same beta I'm using.
Works well too.

Help - Battery Drain excessive

*jump to ashtricks for immediate problems without reading software/ROM changes.
I know this is going to be made especially difficult with all the different software/combo's that can be loaded, but I have to post this up and see if any one else has seen this and if it might be hardware or software.
I have a HERMS 100 (8525). I first got the phone in April with WM5 (don't know which build they might have been on then) and which ever Radio was coming on them then. My battery would usually last 2 days with my avg use.
This has been the case threw upgrades until the last 2-3 months. I upgraded From one version of WM6 to VP3G's 2.X build of WM6 and I upgraded the radio to which ever version was the newest at that time (maybe 1.47 or 1.50). I Noticed a sudden drop in battery life, but the phone pretty much always made it a full day even with high use, so I didn't think much of it. I did notice about this time that sometimes the phone would alarm me and say it had 20% battery remaining, but if I rebooted the phone it would say 80 or 90% power remaining when it came back on and work fine the rest of the day.
The following has been over the last month. I upgraded to VP3G's 3.0 and again later to 3.6 and again to 3.62. I noticed the battery continued to degrade throughout this time. So I upgraded the radio to 1.54. The battery continued to go down hill at an even rate, but I noticed something else, the battery would not take very long to charge, but was dying faster and faster.
Well I started tracking and experimenting. Starting last week (no change in software or ROM's for the last 2 or 3 weeks) the battery would rarely make it through the day even when the phone was not in use any during the day (Granted I get no cell service at my desk at work, but I never have even back when the phone would last 2 days searching for signal). Most days last week it wouldn't make it 5 hours from being unplugged even when the phone wasn't in use. I decided to run the battery all the way down to where it wouldn't even turn the phone on anymore as I had heard sometimes you needed to do that after a rom upgrade. It did not help, but I noticed that the phone said the battery was fully charged within 2 hours from being completely dead.
*
Today was the worst, I unplugged it after being plugged in all night. Unplugged it at 6:45am. I did not use the phone, it just stayed in standby (I hadn't even taken it out of standby any today. I am at work with no service (When I say no service, I don't mean sometimes it finds something, I mean no cell service from any carrier makes it past 10 feet of the front doors entering the building and I am about 150 feet from the closest wall to the outside). I grab the phone at around 10:30am to check on a meeting notice, clicked on the phone to wake up and the battery alarm alerted and the battery said I only had 20% power remaining. In 5 minutes of doing what I was doing the battery had gone down to 10% remaining (so the phone went from lost 90% of it's power, never being used in less then 4 hours). I went back to my desk, plugged the phone back in and within an hour I noticed the amber light on the front that I relate it to telling me it's charging had turned green, I unplugged it and checked it and the battery said it was full 100%. Could the battery really charge that fast?
*
I know this would be easier if I could remember what radio and what version of WM5 came on this phone and loaded it back on and I am in the middle of downgrading the radio since I had ran WM6 with no battery issues separate from WM5 until I did that one upgrade with the radio. I guess I am curious if this could be a hardware (phone or battery) where it's not charging fully or if this seems to be a software issue.
I know all the factors that can be involved make this hard, but thanks for any responses you guys can give.

ok, how about this one, Is my battery screwed? I notice while I am using the phone the battery gets really hot. Today it did the same thing of all of a sudden saying I had 10% power after only using it for 5 mintues, rebooted the phone and now I am back to 70%.

Hi,
There's a lot on here about this problem. Have you read the wiki?
Some solutions you might try:
- turn wifi off.
- turn off all beams
- put in the fake server trick.
- search to see if you have any software that continuously polls the battery or is seeking an exchange server
- ensure all your apps fully close rather than minimise
- invest in a new battery.
WB

Thanks, I have gone through the wiki Continuasly since I got the phone in April, but with all the stuff out there, I could have easily missed something.
- turn wifi off - Never turn it on
- turn off all beams - Beaming disabled
- put in the fake server trick - Have to research that one
- search to see if you have any software that continuously polls the battery or is seeking an exchange server - have to check, don't have exchange server setup. I do have it checking emails every 15 minutes, but I never had any issues with that setting and the battery lasting a couple of days
- ensure all your apps fully close rather than minimise - X button set to close not minimize and I often check it to see whats running.
- invest in a new battery. - Will be doing that next. Just waiting to see what case I might get for Christmas.
Thanks again, I will research those other items.

I had a similar problem where the stock battery would only ever last for ~7-8 hours - even on standby. I got an extended life 3000mAh battery and that managed to last for about 14 hours.
I had a talk to HTC and they agreed to warranty claim it. I'm still waiting for it back... It was sent back to them on 14/11, and I'm still waiting.

Stop your device checking for emails for a few days and ses what happens. Definitely install the fake server trick. Activesync continuosly trying to do its dirty work can be a pain in the arsenal, at times.
Let us know how you get on.

Well I turned off email checks last night and disabled the radio this morning so it wouldn't search for signal when coming to work and set the phone on my desk. I never used it this morning, just had it sitting on my desk in standby, until about 4 hours after I took it off the charger and the phone buzzed me and when I checked the phone the battery said 0% remaining and the phone cut off a few seconds later (now I am sure if I would have turned it back on the battery would say something like 70%, but I didn't do that this time). I left the phone off and plugged it into the computer to charge, the LED on the front come on amber for about 20 minutes then went to green. I turned the phone on and it says 100%. I don't see how the battery went from 0 to 100 in a matter of 20 minutes.
I did a lot of searching the last couple of days and phone issues from email to bad manufactured batteries (which I happen to have the brand someone suggested as a bad one), I also saw people pointing out do the fake server trick, yet I can't find a single time where anyone said what the trick is or how to do it. Not even in the WIKI where the trick was mentioned as a possible fix (or google for that matter, just the same words first posted in a thread here about it).
So, how do you do this server trick?
I plan to get a new battery after Christmas at any rate.

Check this thread:
http://forum.xda-developers.com/showthread.php?t=338421&highlight=fake+server+trick
I was having the same battery drain problem (less than 8 hrs on a full charge), I did the fake server and turned off auto day light saving time checking the clock settings, I now get 12 - 15 hrs on a full charge.
I'm running vp3G's 3.62.3 AT&T ROM with radio 1.54.07.00

Thanks! I was just finishing flashing a new ROM when I saw this. I did the fake server trick, but this rom doesn't have the Dya Light Savings time option where the instructions say it should be. Maybe that's all removed by this rom. TIme will tell.
Thanks again.

@ Firehawkns
hey buddy!!
I am using a JasJam for the last 2 months. i dont know if my reply is useful to you or not. As far as battery life is concerned am impressed with mine. Am using TNT's latest ROM and my radio version is 1.54.07.00. I use my phone all day with couple of calls that last about 2-3 min each. But every night I get calls from my gf, to whom I talk for 3 hours straight(mostly starting from 11pm to 2 am) and every day I put my phone to charge after I finish the call. So after finishing the call I still have 50% of battery. Moreover our call starts right after I leave work at 11pm so by the time I reach home which is around 11.30pm my phone connects to wifi too. So all the time am on the call as well as an active wifi connection.
So as per my experience the battery life is cool. So try TNT ROM!!!

Interestingly enough, now I've got my phone back from the warranty claim, it's only drawing 81mA with backlight on, no wifi or BT. Before sending it back, it was drawing ~180mA with backlight on, no wifi or BT.
This will just about double the battery life that I get in theory...
Install BatteryStatus on your device and see what it tells you.

That is a cool program.
First off I really hope it isn't the phone, for one it's my third one from Cingular since the first two died within 2 weeks (back in may), second it's got one big gash down the corner where it came out of the holder and hit the road one day. I think that would be just enough reason for them to not do anything with it.
Anyway, I am going to replace the battery because I can't figure out why the phone is doing things like saying it has 20% batt remaing, then I reboot and it goes to 70%. I am hoping this is a battery issue. So far the phone has been unplugged for a tad less then one hour, has not been used and the battery meter is on 90%.
Battery Status is a kick butt program and I plan to do some searching today to see if people have benchmarked there ratings/draw. I notice mine jumps randomly. With wifi, BT, all programs all terminated, backlight on the lowest it will go and radio has one bar 3g sometimes, two bars Edge sometimes, but didn't change during watching this list below, but the MA does this every 5 second refresh:
111--190----125-----109----250----210-----140----135----226---111---etc.
I am currently running a barebones fresh flash WM6 rom with nothing installed except Cingulars media net/ISP settings, radio is 1.47.10. Going to try 1.50 today I think.
I turned the radio off just now and the MA went down (expected) to 84 and is jumping between that and 104. The battery has dropped to 80% since I listed 90 above. The phone has now been unplugged for right at an hour. Also it might be interesting to note that the little battery percent/bar icon on the "Battery Status" software once in a while will display -1% like it is right now, the phones battery display says 80% and when I tap the battery icon on battery status it jumps to 80%.
Anyway, I am just listing points since this thread is here, I know I need to replace the battery first before any additional insight can be brought forward.
Thanks everyone.

Hmm.. On my Schaps 4.22full, radio 1.54.00 on good reception (on Finnish network) I get around 30 mA with GSM and 3G when idling(no wifi, no bluetooth, no beam, backlight around halfway). With airplane mode on I get around 28 mA. Tried with backlight dimmest and the drain was 15mA on GSM network.
Usually I put the 3G off so the battery would last longer.
The phone takes more power when searching the network so it would be a good idea trying to switch the phone part off at your office.

Well, looks like it was indeed the battery. Over the last week the phone would randomly shut off (about 4 times a day), the battery would be at 10% within 4 hours even if the phone hadn't been used, and while using the phone you could almost watch the battery go from 90% to 30% within a 5 minute talk time, reboot the phone and it would be back at 80%.
Put in the new battery yesterday after charging over night and the phone not only didn't shut off at any point, but I had 60% power remaining by the end of the day (with some data and voice use).
The old battery was a Dynapack from China, that I had read on here is prone to defects.
Thanks for the help everyone, wish I would have gotten a new batt sooner.

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.

Battery life is extremely short

Hey guys, I've had the phone since Saturday and even though I've been through a few charge cycles my battery only lasts about 6-8 hours. Today I took the phone off the charger at 10:00 AM and it died on me at 5:45 PM. I only texted a few times and only did an hour or so of Slacker Radio. Seems a little low for what I'm doing with the phone.
I am on Kumar's classic 2.2 ROM with 2.11 radio.

A lot of things can drain the battery, 3g on in a no 3g area, weather updates, twitter , email updates ...
But If I was you I would try a diff radio ... I get a full day out of mine at this point a little more ...

I've tried 2.12 as well and the battery didn't improve.

Is your activesync checking as items come in? That's what drained mine terribly. Basically, it can be a ton of things that make your battery drain such as:
1. backlight
2. agps
3. certain programs
4. etc
You'd have to list a bunch of stuff on what you're doing to your phone

Can you turn activesync off? If so, how?
Also, any other tips to save battery life?

Definitely lower down the screen brightness to 20%, turn off Bluetooth and WiFi, don't let things like Twitter and your e-mail update so often.
Also using the internet/music/videos will drain quite a bit of power, especially if you use the internet while listening to music.

Yeah I mainly use internet radio while at work. Would using WiFi be easier on the battery than using 3G/H?

Yes, I've done it both ways and wifi most definitely draws less juice when streaming data than 3g (and when idle too, for that matter)

do you think it matters whether you install programs on your SD card or on the device?
i have CHT installed on the SD card and i can't make it 8 hrs on light usage.

I only have 3 apps installed so far, but it's on the device.
Also, is there a way to have the default wallpapers without animation? I'm sure that doesn't help the battery every time I unlock the phone either.

Yes. Try installing it on and running it from the phone instead, I'm sure you'll see at least a noticible difference.
Honestly, there's really not much of any reason to install apps on the SD card with this phone...there's more storage available than even most power users would ever come close to filling.

im in teh same boat. had it since march. on elegancia rom which people say is great for battery. on 2.12
now im in a bad service area in my basement often so i know sometimes thats the cause. but even at the gym 40 mins of internet radio dropped my battery almost 20 percent.
if i do nothing with the phone it usually drops 5 pct an hour 10 pct with moderate use but 20 easily if i do anything on the web over 3g or wifi. its awful
oh and i have lumos configured, i only have email connect every 2 hours and weather every 6. nothing else connects

Wow! your phone's battery usage sounds a little over the top. Might want to try using a different radio. 2.08 has given me the best signal/battery efficiency, but of course that varies from phone to phone.
Also, I bought a 2600 mAh battery so now I'm not afraid to use my phone. As long as you don't mind the extra bulk it adds to the back of the phone , I would suggest getting an extended battery to everyone complaining about how their battery dies too fast.

I will back up the statement that putting apps in main memory will save you battery ...
The less your phone has to access the SDcard the less power it uses.
A big thing is if you have any apps that run all the time that are on the SDcard , not only does it drain battery but will degrade the performance of the SDcard .

Anyone else have any ideas?

talked to tmo on webchat last night got em to send me a new battery
so if nothin helps at least il have two

I'm trying that method right now, we'll see what happens.

Bad battry life... anyone ?

Hi guys, I have my omnia 7 for less then a week now and I found it's battery life terrible, the worst performance ever. It drys off in less then a half of day with general use. I fill the battery to 100% over the night and then I wake up in the morning at 5.30am and when I'm back from school sometimes it's allmost empty, sometimes is at about 20% with a usage of About 15 mins of gaming, some browsing/facebook.. few calls and sms and an hour or two of music playback.
I have wifi, bluetooh, push mail, feedback and locations off. Have also been reading on the social.answers microsoft forum about that and there were different tought. I'm wondering how is it with yours.. is it REALLY this bad or it is something wrong with my phone/battery. I don't want to take it back if all are like this as it will be at least one week on service.

mine is on par with any other smartphone ive owned. i can get 24 hours out of it comfortable. thats with about 30 mins calls, 15-20 sms, 30-40 mins gaming, wifi, bluetooth, location & feedback all turned on, windows live & facebook hourly sync & 5 email accounts syncing between every hour & every 2 hours. i have noticed battery life seems to suffer when i use last.fm over HSDPA so maybe its something related to music playback. but even with 3-4 hours of last.fm im still getting 13-14 hours.

ok thank you guys for reply.. I'm deffinetly taking it back for a replacement on monday.

It could be some app running under the lock screen draining your battery, like a game or Last.fm... other than that, yeah, sounds like a replacement is in order

Nothing running in background. anyway I'll take it back in monday and ask them for a replacement if not, I'll have to wait a week or two to get it back from repair service... trought I hope to get it back till new year.

Maybe consider just buying a new battery?

you should definitely ask for a new battery first, before sending it to service. In the end all is made in China... P.s. My bat. lasts the same as descibed by the others. 1-1,5 day...

giving 390€ with 24 months of contract, using the device for one week and you really think I'm as dumb to buy a new battery as I have 1 year warranty on battery and other accesories ? ... Really ?

Thanks, I'll see what it can be done..

my omnia7 leasts longer than my galaxys with data and email sync .. so no problem

Ok I was at my carrier and they said that the phone needs to be send on service (no replacement options) so I'll probobly send it after new year.
But I notice that when I'm at home (I live about 7-8km out of the city) my battery last muuuuuch longer, actually enugh for what I expect - 2h of music, about 2h web and of market browsing (connected to home wifi + mobile data enabled connected on 3g+ full signal) and when I'm in school (city centre) it drys my batery much faster. Today after 3h with 20min of music and 5 min of web browsing it fell on less than 50% and few hours later on -20% and then it turned off. (same if connected to school wifi or just 3g+ also with full signal)... I really don't get it .
And many of my school mates have the same carrier but don't have any of this problem... might it be somekind of carrier transmitor selectnig bug with windows phone 7 or what ?

Things to note - browsing with WiFi requires less power than browsing over 3G - 3G browsing will suck out your battery a lot faster. (The phone will not use your mobile data connection if you're over WiFi) Also, depending on the lighting conditions, your screen auto brightness will probably also have your screen on a lower brightness setting in your house.
That, and I don't really recommened using your phone as your primary Music/Video palyer if you're serious about battery life - that does a good job of sucking your battery too, and you'll ntoice most of the people getting good battery life aren't really using it as their primary media player.

actually I tested it with using at home with same settings (brightnes to low, wifi/3g off/on) and I can see that when I'm in the city centre it sucks the battery in only few hours with data connection on and not connected to wifi so I assume that my operator wich recently updated it's network did something wrong as my school mates have noticed this too but none of them isn't using a smartphone on this network so it isn't so obvius. I temporary solved the problem with turning off data connection when I'm in the centre and turning it on only when I need it and when I'm out of the centre.

I also noticed my battery life sucked when I had the official twitter application installed on it.
Today I left it charging for 8 hours on my laptop and the battery meter barely moved, I removed Twitter and hey presto it started to charge properly.
Back to Beezz and now all is ok

Apps don't run in the background so it is pretty much impossible for twitter to be draining your battery if it is not open.

Maybe it was just a coincidence but as soon as I removed this app my battery started to charge.
Unless it was a one off issue with charging over usb.

my batterylife is the best ive ever had in a smartphone ... i need a custom rom on my galaxy s with android to get close to the batterylife of my omnia 7 ... i am using hsdpa with the same provider on both phones permantly and im syncing emails with them ... even with gaming (sims 3 or nfs underground) the windows phone least longer.

Not at all. There could me a memory leak in the .NET/silverlight runtime - even Microsoft developers make mistakes
Tbh, I have the Twitter app installed also and my battery life is as good as can be expected with a modern smartphone: 1.5 days heavy use (Music, Twitter, Facebook, web browsing & constant SMS/e-mail)

may I ask somebody for a favor ? Under the diagnosis (call ##634#) type *#2*# (battery diagnosis) and please check what does it say on the third screen at the last line "Result". For me it's "Pass/Fail". Might this "fail" mean it's something wrong with the battery ?
PS. after dialing ##634# a shortcut for diagnosis will show up in the apps menu... just delete it if you don't need it.
And to get to the third screen use the big arrow on the top =)
