I let my phone discharge fully till it turned itself off!
Charged it for 4 or 5 hours.
Now I used it to make 3 short calls (5mins each) and send 10 or so texts, and surf for about 5 minutes, use google sjy mpas for 5minutes, showcase some video to some friends 2mins, general messing 10mins altogether.
Phone is up 40hours now (since charge) and still at 80%. I am very impressed.
I put it to airplane mode between 12am and 7am though as I don't like to be woken by drunk friends texts at 2am etc. (it happens sometimes).
I think those of us (me included) who slated the battery life originally didn't relaise we were using the phone non-stop pretty much for the entire day, trying out all the features on it. I doubt the first week of use will be "typical use" for ANY user
Happy Days
My battery on day one seems fine, 12.5 hours running so far, screen at 100%, everything on automatic syncing (and I mean everything, Weather, Twitter, FB, Gmail etc), continuous WiFi connection throughout, plenty of "first day" playing around and still sitting at something like 20%. With a few more charges and more typical use will last a day just fine, which is all I ask, since I always charge my phones overnight...
When i got my phone i let it run out as it had half power, i overcharged it a few hours then let it die, then i do the same again but not overcharge it and let it die. Now i charge it when i need to but i seem to be getting 3 days worth with usage out of it and i use gps, web and have things on auto. Seems to be much better than when i first had it as the battery didnt even last a day but now its past 2 days.
I assume with newer firmwares etc this will improve
My battery life seems to get worse. I charged it fully ... it has been on for 6 hours and I have put 3g on for a while (1hour max and i barely have used it) and my battery is already 60% ... is that poor?? This is my second phone as well!!!

I thought a full charge only required 3 hours..?
Anyone having surprisingly short battery life go into the phone keypad and dial in *#*#4636#*#*, when you key in that last * you will be taken to a testing menu (I've added a contact with this number and when in the dialer I can long press on the number as select edit number before calling to take me to this screen)
In this menu there are options to see phone and battery information as well as usage statistics for apps. The best battery option is "battery history" this shows you what apps are using your battery for various things such as network and processor usage. You can see this data for since you last rebooted your phone, unplugged it or for the whole life of the phone.
The first important part is "other usage", "running" shows you the percentage of the time your phone has been awake and doing stuff, "screen on" is the percentage of time your screen has been on, the difference between these two is when your phone has the screen is turned off but the phone is still working such as when syncing. Ideally you want these two percentages to be as close together as possible but it depends on how much syncing you have going on automatically in the background. If your running percentage is at or near 100% then an app is keeping your phone awake and using battery.
Next we have "partial awake use", this is what as been running in the background when you have the screen turned off and any apps that process or sync in the background would be listed here, the longer the bar, the bigger the drain on your battery. On my phone now the biggest bar by far is android system but it is still only small.
With "sensor usage" this is what has been using your sensors, games that use the sensors will feature heavily here.
"Gps usage" is again pretty self explanatory, whatever has been using gps.
"Network usage" was a real eye opener for me, I found out that an app was downloading megs of data all day and dwarfed all the other bars and was the reason for my bad battery life. Here the blue part of the bar is download and the red part is upload.
And lastly "cpu usage" on mine these are all practically non-existent but if anything is using massive amounts of processing it will show up here.
I only found out about this the other day but it has helped my battery life substantially, I used to take it off charge in the morning and be down to around 60% by lunch time, now I'm at 98%. I did this by uninstalling any apps that used too much battery and that I didn't really use very much as well as the vampire apps that were running and syncing continuously in the background, I also reduced the frequency at which some of my services such as stocks, email and weather synced, and used it on a low brightness when possible.
This is my first android device and I can now happily use it without the fear of running out of battery before the days end
Wow, thanks andybut85, that was a very informative post!
If you download Spare Parts from the Market it gives you access to the same info - instead of 'dialing' to test mode.

My biggest is "Calendar" (54mins from Boot, compared to 1min for Andriod System!)
What Calendar could this be? Im syncing from Google Calendar, so will it be that? If so, wouldnt my email syncing show up as constantly on too?
Or could it be some other App that is making it run constantly?
Any help gratefully received.

Have a look for "Total in all time" with mine the calendar is roughly half that of android system, it could be that recently your calendar has had to sync for a long time, this could be a one off or if it's still high for the total time it could be a deeper problem. You could also try rebooting and seeing if it occurs again.

I'm still having problems with battery drain.
My Desire will not last a day
Installed Juiceplotter to find out when and why my battery drops so fast.
See attached image.
The battery drains very fast when i USE the phone, so when the screen is on. (20% in one hour)
I have two push email account activated, one with the HTC Exchange, and one with TouchDown.
But that doesn't explain the drops when phone is active.
Anyone else having this kind of batterydrain ?
I have positive "story" about battery too. Im on second charging. Saturday at 1:00 Im unplug it from charger and now 34h later Im on 7/10 battery.
Im make few calls(cca. 10 calls long 1-3min), few times(cca. 3-5x) check emails accounts(4 pop3 email accountes), quick test sygic navigation, little search on market(install calendar widget and some other app), and play few levels of Teeter...
3G is turned ON
GPS, WIFI is turned OFF
Also automatic sync is for most things disabled or setup to sync 1x per day...
Hmm Can't say I'm impressed by my battery life... it dropped 20% overnight..
I''ll keep an eye out on what's running and see if i can fine tune, but turning things off seems to be a bit pointless as it is made for use not just sit on a desk being pretty.

i got great battery life at home over the weekend connected to my wi-fi network.. i have a feeling its the crappy edge reception in my office thats eating into battery life during the week..

yep, that sounds highly plausible. Bad or weak connections to the network (especially mobile internet connections) will really drain a battery as the phone needs to use more power to maintain adequate connection strength.
you can check your signal strength in the "settings / network strength" section. I notice in good 3G areas my connection is -95dBm or higher. At work (which is in some sort of black spot in Dublin) I only get EDGE connection and my signal strength is about -80 to -85dBm. I bet this makes a big difference to battery life, especially if I try browsing or data connection.
my signal strength at work is -91 dbm...
i'm guessing bigger numbers are worse?

spare parts showed me that "media" was using the network a lot, bowever i cant work out what this corresponds to, it says DRM protected content storage, download manager and media storage. shows as having downloaded several megs
i use spotify for music, anyone any ides what these could be?
thanks
only guess but i'd say its spotify.. i have used servcies like that in the past on my pc.. and they sometimes have a lot of downloading going on that you dont even ask for!... worth checking out..

yes it could be, but spotify also comes up as a separate user of resources and i tested it since unplugging when spotify wasnt running and "media" still comes up as the biggest user.
makes me think that its not spotify

Hi everyone,
I bought my new Desire two days ago, and im noticing a really fast battery drain.
I had a Hero before, and although it had a smaller battery, i would charge it every two days.
When i check tha battery usage, i can see big percentages in cell standby, phone idle and android system. (Its where the percentages should be really low imo..) Things like display, bluetooth etc that were supposed to drain more my phone's battery have much lower percentages..
Maybe all this comes from the snapdragon cpu??
I also have 3g off, always on mobile switched off and brigthness to a really low level (although i think amoled displays dont drain the battery that much)
My battery will last one day the MOST..
I know that the new battery has to be charged a few times before it has its full potential, but i think that somehow battery is getting drained..any tips???
Thanks,
T.
I to have this same issue if anyone has any ideas on this would be great

You just need to relax
My Desire couldn't get through even one day of usage when I first got it. Several things contributed to this:
1. The battery is not fully conditioned
2. The device is new so I want to play with it all the time. I'd turn it on randomly for no reason whatsoever.
3. I use several widgets that requires updating just because of the novelty (ie, Friendstream, News, Twitter, Stocks, Weather)
Now, I go through about 60-70% charge per day which is fine by me. The only things that have changed is this:
1. The battery has gone though several recharge cycles
2. I only turn on my device when I really want to do something on it.
3. I no longer keep many of the widgets that requires updating and for those that I do keep, I make it update less often.
Eg, Updating your weather every hour is not necessary. Every 3 or 6 hours makes more sense.
Eg. Rather than having your Twitter or Friendstream widget on your homescreen, why not just have a shortcut that goes directly to the application and then set it to sync on launch? It's better than having your widget update when you're not even looking.
Also get an app like battery indicator to give you a numeric readout of your battery life left. My android battery indicator was in the red yesterday and complaining I had to recharge, but battery indicator said I had 12% left and I got 30mins more constant music playing out of it before I got to work and it was still on 5%.
when the battery is running low - you get a button to show battery usage stats.. can you get these through some of the widgets or a comparable app from the market?
almost every update is set to to once a day, or every six or eight hours...so i dont think that the updates drain the battery that much..
its just weird that the most battery usage comes from call standby, phone idle, or android system..
mine was the same, i found its due to sense & all the background updates. currently running helix2 homescreen & now I only go thru abt 50% battery each day & that includes 2 hrs of music each morning.

alright i know this seems stupid but remove all your task killers, i got rid of mine this morning and my battery has been fine normally by now i would have plugged my phone in for a juice up, but not today i had bluetooth on by accident all morning and by the end of the morning it was still at 70% yes i know it sounds stupid but it actually helps
There many interesting suggestions posted here and like most i've been absolutely hammering the battery on my handset simply because its a new and highly entertaining/useful device.
Here's some of my findings...
The battery/app usage screen can be quickly accessed by pressing the menu button on the home screen, selecting settings and "about phone". It helped me nail down some of apps causing excessive drain.
Much like the iphone and any other high powered smart phone, high screen brightness, wireless LAN, bluetooth, 3G and the GPS receiver all take its toll on the battery. One of the biggest drainers is the GPS receiver so use it sparingly, I initially had it on permanently for some of the maps functions but the battery was lasting about half a day! Sadly i've noticed the radio is also a bit of drainer, which is a shame because it makes a nice alternative to MP3 playback.
Data updates and notifications again much like the iPhone have a surprising impact on battery life so set them to manual or long intervals.
In summary, learn as quickly as possible to get the most out of your smart phone by balancing out the hardware and software options.
As a sidenote, I was previously an iPhone fan but this handset has really changed my opinion of how a smartphone should really be. The combination of excellent hardware, an OS thats clearly designed from the ground up for mobile use and an ever growing (open) software base, will in the long term win over Apple's over analy retentive ethos! Top marks also to HTC for their sense UI and application suite, it works on top of Android almost as if it was always part of the OS itself and I just love the integration of social networking features....leaves the iPhone in the dust!
I have noticed that Turning off the Data Connection helps a lot.
Last night I turned data off, before I plugged my phone in for charging. In the morning the battery was showing MAX power. Where normally in the morning would be 97%, because charging stops once the battery is full.
I am still experimenting with all the Apps & Widgets that turn data access ON/OFF, but my conclusions so far, just get a simple widget from the market, and keep data connection off, until you need it.
There is an app that turns data connection off once the screen goes off, but if you download something or wait for something to load and the screen goes off, data will also be switched off which is not what you need.
Ok I've had my desire now for couple if weeks. I've read many many posts regarding battery issues so please bear with me.
I've come from iPhone 3gs and estimate my battery is seeing 25 percent less capability.
There are it appears many settings for internet connection. (Always enabled, auto sync, background sync, connect to internet, then individual settings for certain apps when they wanna sync. And then WiFi settings. What I'm after is to kill the internet completely when my phone is not in use, (this is regretable but have to save battery).
What I want is to kill the internet completely when the phone is not in use. No background, no sending hunting for signal etc. Then in one click I wanna connect. AND have the apps sync that I want synced. And have full internet etc. Then in ONE click shut internet off compleley. Is the best way to do this, by setting up your auto sync and background to be always on. Background always on, everything always on or connected, then hold the power button to wake the phone but hold it till you get menu and then select connect to internet from one of the options. Then when I pit the phone down, hold power key, then select disconnect from internet. Will this work and kill my internet connection 100 percent? And get everything synchronized when I turn it on?
Not interested in juice defender, read some bad stories (aswell as good)
Thanks.
Long press the power button, click 'Mobile network' to toggle it on or off.
I use this settings when in work as I have a very poor 3G/H signal in my office, other wise the 3G/H singal drops and connects like a yo-yo all day long draining my battery like crazy! I turn it back on when I'm leaving work. This way I still get calls/texts while in work and I'm sitting at my computer for my internet.
JuiceDefender (even the free version) is working wonders for my battery life. The basic version forces your mobile Internet connectivity to only turn on for 1 minute for every 15...amazing what difference this makes.
I've been using it for the last three days or so in basic mode, and my multiplier is already over x2.
The only downsides I've found are that the 3G/HSDPA is a little slow at "waking up" if I want to use it if JuiceDefender has previously turned it off...I have to have the screen turned on for about 20 secs before a connection initiates - it's a relatively small price to pay, however.
As a rule, I have auto-syncing turned off during office hours since I'm in front of my PC at these times, so don't need to have GMail, NewsRob, Weather, Facebook, Twitter etc. updating on the phone. I turn syncing back on just before I leave the office - and there is plenty of stuff then synced up ready for me to look at whilst on the train home. I leave syncing on for the rest of the night whilst I have WiFi on the phone - and this seems to draw *far* less battery than when 3G/HSDPA is constantly on.
With this routine, I'm easily getting 24 hours out of the phone now...
The real battery killer is when you're using Internet-enabled services in a patchy area. The battery drains away extremely rapidly I've found. In can easily lose up to 40% whilst on the train home (which takes no more than 1hr 20mins) whilst I'm trying to use the Internet etc. as it is constantly cycling between cells moving between G-3G-HSDPA...

I'll agree with everything rodhull says, especially the lag after switching the screen on. But I know the developer is working hard to resolve this and other issues. JD looks like it will very shortly be an excellent solution to this, which is really an HTC problem - they should have provided a better battery!
I got my Desire a week ago and the first two days it drained in no time.
Today i have used the phone for playing, surfing, talking, mail, used wifi and gps . and I still have 48% left on the Battery.
Time since last charge is 16 hours and 4 minutes.
I am not doing anything special to preserve the battery

Me too, when at home my battery uses about 1-2% per hour with everything syncing and stuff. When at work, it's 6-8% per hour and it's switching between 3G and 2g the entire day. This seems to have a very big influence on battery life.
Hi All.. Just visiting from the X10 pages.. we're having similar battery issues over there too... suspect that these "super smartphones" are really battery killers... A lot of people on the X10 seem to be getting much better battery life now - I got c.40 hours out of mine earlier this week - with wifi usage - no BT and no GPS... There seems to be a few useful things you can try.. first of all - most people have now ditched Juice Defender.. concluding that it doesn't actually help at all.. if anything I reckon it was using more juice..
Wifi sleep policy - set one.. !
Switch data services off when you don't need them (when asleep etc).
Specifying just 2G/ GPRS when in a weak 3G area..
install task manager or ATK to kill apps that run in the background.. sucking up juice!
Hope this helps some!
I've heard some people say they get 3 days out of their desires and others saying they get just over a day.
This thread it would be great to collect a list of people with desires and their average battery life as well as a list of apps they have installed and widgets on display and maybe the rom they are using.
Just trying to work out
I'm going to collect data and put something up tomorrow - but I noticed last night that my battery went down really quickly when my Alarm went off (using Gentle Alarm) I also confirmed this using JuicePlotter which showed the battery sharply decrease just at the same time in which my alarm was set to go off.
I also noticed that having wifi turned on didnt seem to effect battery life that much...
Yeah my battery lasts really well leaving WI-FI on too. Not sure why others have an issue with it.
My battery will last a day tops turning on from 7.30 and off again around 12am ish
During day I will use Seemic (on manual update) and use FB on net every now and then.
May occasionally go to the Market for Updates.
I only use mobile Network when I need to so I turn off and on when required.
I will play Word Up and Solitaire for 30 -40 mins a day roughly.
Battery % will vary between 65 - 45 by 6.30 pm
Today it is down to 75% at 2.10pm - although I've not played any games today so far.
I bought an X10 and returned it because the battery wouldn't last even a day despite having all kinds of task-killing crap installed.
Then I bought a Desire and had the same problem - 6, maybe 7 hours of battery.
I found a post on some obscure blog that helped me track down the culprit: there are apps that don't let the device go to sleep completely. I had two of them. And Android (at least the HTCs) have a built-in function to see exactly what those processes are:
From the dialer: *#*#INFO#*#*, choose Battery History from the menu and then Partial Wake Usage. Nothing should have more than a tiny fraction of a bar. But on mine, Grooveshark was using 99%. I uninstalled it, tried again a few hours later and saw that Mikandi was using 99%. I uninstalled that, and now I'm getting more than 24 hours of heavy use.
Some apps just don't behave.
Why would Dialer App have such a high network usage?

Wouldn't the dialer use the network to call people when you dial?
Thanks for the "cheat code" on the hidden menu. Very interesting.
I can sometimes squeeze 2 days out of my battery. I'll only get a day and a half on this charge though because of lots of txting and facebook use.
I found this menu option in Settings > "accounts & sync" > Background Data. I turned this off and seem to get a little more battery.
Changing the brightness down a bit helps, and i'll set the screen timeout to lower as its at 1 minute now. Plus If I use friend stream instead of the facebook widget then it updates when I want to and doesnt keep active.
Least amount of battery time i've had is a day. I never turn my phone off.
I never get a full day out of mine, maybe 8-10 hours max... I have no idea how some people claim 3 days, I'm not exactly a power user!
Stock ROM (not a provider one, just generic) on T-Mobile UK network
Wi-Fi and GPS off
Widgets: Standard Flip Clock, SMS, FriendStream, Stocks (2hr update), Agenda, News (2hr Update)
Market Programmes: K9 Mail (1Hr e-mail updating), ES File Explorer, Shazam, Voice Search, Pkt Ebay, Tricorder, UK TV Guide, GBCoid
In Standby (screen off), not using web, not calling, not texting, not using apps, I lose around 10% per hour, faster if anything at all is on.
Oddly, despite the very poor (for me anyway) standby life, in call life seems really good, I made a call last night for an hour, where phone was in the orange phase when I started and still hadn't gone red at the end...

I wanted to try turning background data off but sadly the market does not work when you have this turned off (a warning pops up when you try)

True re the dialer. Was thinking network as on net use.
anyone got background data or mobile data turned off?
if so whats your battery life like?
also anyone tried with 3G on and compared to GSM ONLY?

Well the only app that have a bigger bar is Android System... Is this normal?
Settings ; About phone ; Battery ; Battery use and it will tell you when it was last unplugged and what has been using it.
4h 27m
Cell standby - 45%
Phone idle - 45%
Wifi -7%
Android system - 5%
Display - 2%
Obviously you can see from that I've hardly used it. A few texts, checking email periodically. Display brightness is on full, weather update is set to manual. Only have a few apps installed. Main one being data counter widget.
2000kb wifi
780kb cell.
Oh, and SystemPanel, tells me I have 93%.
Switch off 3g when you don't need it,this can nearly double your standby/idle time ,use a 2g-3g toggle if its a pain.
Juice defender with its plotter can give you very useful info on when your phone is using its battery the most.
On idle with 2g 1% per hour is normal, with 3g 2-4 %.
As soon as that screen goes on start thinking 15-20% per hour!
Most smart phones are the same,my x1 ,touch pro all got caned when I first got them,but a bit of experience and a few tweaks later they were doing 3-4 days.
Also flatten it and fully charge it when switched off helps too.
My battery life is pitiful too, im a pretty light user now ive had time to play with the phone for a while but battery will always need to be put on charge by around 10pm when only unplugged around 7am the same day.
I bought up the partial wake usage list and UID followed by a number is using twice the power of Android System.
Does anyone know what the UID is?
My battery life was rubbish until i updated the radio version to 32.37.00.32U_4.06.00.16_2. I am also using MCR3.1
Before my battery life would be fully discharged within 7 hours. Now i have 1day+ Not too sure as i now have a brodit car mount that charges my phone during my commute.

Stating the obvious, but if you don't use your phone, your battery will last a long time!
Personally I need to use my phone (otherwise why would I have bought it) so have push email running with full Exchange sync 8 till 8, FB & Twitter syncing once an hour, spend a couple of hours a day making calls, connect to WiFi using my iPass account whenever a hotspot is available and spend a lot of time dealing with emails etc.
I put my "less than a day" battery life down to the fact that my screen is on and doing stuff for much of that time.
Of course if I just leave the phone on the desk at the side of me and don't touch it all day, even with push mail and all that sync, if the screen is not turned on much, I get 2 days.
It's the screen that eats the battery. The more it is on, the shorter the time between charges.
Wow I don't understand how you people get such amazing battery life!
I am no noob anymore regarding Android and Smartphone's in general, so I understand most 'hints & tricks' in this thread. But simply for me this does not work.
Some important stuff:
- I ALWAYS have 2G on, never 3G.
- I use wifi at home and in most places I go
- I have almost everything set to 'manual' updating
Ok.
For example my last situation:
I unplugged it at 23.30 yesterday. I used it for a little bit, over wifi. Checking twitter, surfing the web, watching some video's in HTC Flash Player. I went to bed around 02.00, watched some Law & Order that's why it was so late. So before turning off the lights, I turned wifi off. The battery was around 80-85%, from what I remember.
I wake up at 12.00. The battery was still above 50%, that's for sure. I do some facebook, twitter, news, etc. All over wifi.
And now, just before 17.00, my battery was dead (while I almost typed this entire story on my Desire -.- I was pissed). So that means, about 17 hours? Which about 10 hours I slept and the phone was doing nothing, over 2G!
So yeah... and when I read all your story's about 2 days (48 hours) I am really like: WTF
Some more details:
-No live-wallpaper. Just the black 'carbon' one.
-I used to use LauncherPro beta, but battery life was just as bad. Now I am back on HTC Sense. I have some widgets, like the Calander widget, a small music widget, bookmarks widget, etc.
-I tried to find out what uses the most battery while sleeping with that code and it showed Android System. So nothing weird there.
-Again, everything set to MANUAL updating
-ONLY 2G.
-Brightness set to auto.
So really, I think it's my wifi that sucks the battery life out of my Desire. I remember when I went on a trip and was just 'listning' to music, my battery only dropped like 10 to 15% in 3 hours.
-----------
Btw, I remember that this 'some people have great battery life some people don't' story was the same with the HTC HD2. The only different thing there was that I was one of the people with the 'good' battery life. Now I am on the 'losers' team
Any help would be great!
Hey all, I don't know if anyone has even noticed on their Evo's but on mine, the Android system usually eats most of the battery. I noticed there is a ton of processes under Android system that are running compared to like five on my Hero. I've never seen the core system processes take up more than maybe 15% of the battery, but right now, I'm at like 41% with 16m 6s of CPU total and 47s of CPU foreground. If anyone knows why this is or a way to fix it, please let me know. I'm on the first MR update. I've been able to get a lot of battery stuff figured out, if I can get the system to calm down, then I should be able to get even better battery life than my Hero.
I'm seeing the same thing, android system is at 96% battery use after letting the phone sit overnight. Never saw that on my nexus, this is strange.
Could be related to the fact that everything is syncing up, I just activated last night too.

Yeah, the system seems to have calmed down a bit today, though I also have the OC widget running to keep the processor lower during sleep. I'm guessing its helping, but I'm not sure if there is something else to get it down. I almost never even saw the System show up in usage on my Hero, now its one of the top contributers. I got used to having custom roms on the Hero, but so far all I need on the Evo is unrevoked. I know a lot of people around here don't like it, but I found I only needed a couple of apps that require root and so far love it. That OC widget really comes in handy.
maybe i can clear things up a little bit for you guys...what you see in the battery use section is distributed across 100% of the time since you last had it plugged in. if you notice all the percentage numbers add up to 100%.
if you plug your phone in and turn it on and off on you will see that android system is probably around the 90's thats because android system has used 90+ percent of the phone since you plugged it in....over time that number will lower, becuase other things will start using the battery power... what you see is a percentage based on time. not based on whats actually working RIGHT THEN AND THERE do you guys understand?
I too am having that problem and at 15% battery life warning - it still shows my Android system @ 40-44% usage after 8hrs of work.
I mostly text message all day long due to work - make phone calls and recieve calls from work every hour. GPS on for no more than 15min all day long to get direction when my keymap book doesnt help.
4g off, bluetooth off, background data 15 min only (gps) than off, gps off when not in use, mobile network (3g) off when not in use.
I would have figured my screen being on would have drained my battery life since I check text message every 10-15mins for 8hrs...
So went to work at 9am, 100% life
got off work 6pm, 25% life
I've done all the tricks, cdma only, force stopped a bunch of apps, goggle talk off, sync off, making sure maps/gps has been closed (forced or not)
still disappointed with battery life.
Unrooted Evo
My crappy AT&T Razr lasts me 2-3days with text message + call + 1.5hr of playing Bejeweled a day
*facepalm* you guys don't get it....

check your hardware version there is a thread about different types of evos and it seems like everyone who has the hardware revision 0001 has really bad battery life. i would exchange your device.
Yes we know, Freelancerx, or at least I do. But after over 8 hours and the system is still using more of the battery than anything else is a little disturbing. Never seen that on any other device. I have Hardware 0002.
I have this same issue with hardware version 0002. I run Fresh 1.0.1, i use Netarchy-toastmod kernal, have latest radio. I have also tried Damage Control (did get slightly better battery life out of DC but not amazingly different)
after 7 hrs since unplugged my andriod system is at 39%, cell standby 28% phone idle 20% display 9%.
i dont have bluetooth, wifi or 4g on. I use juicedefender+ultimate to turn off apn when screen is not on. I use set CPU to underclock when i am unplugged and go down to 128 when screen off and i am Stilll lucky if i make it all day with moderate usage.
Every day it is the same andrioid system is around 40% of the usage for the time it was unpluged.
the following is listed under included packages (not sure if this shows the same for everyone or if it shows what packages are running)
BRCMBluetoothService - Bluetooth is not on so if it shows packages running this may be an issue
Sync Feeds - I have all android syncs off and mail at 6 hours
settings storage
Rosie Utility
Acounts & syync
Account and sync settings
settings
HTC Widget Download Manager
Network Location
Setup
HTC Checkin service
Checkin serivce

Android system
Wonder if there is something to the android system on these (ie something not turning off that should) or if we are all just crazy and happen to get the same results.
I had a hardware 0002 model and often experienced the same thing with high system % usage.
My phone was replaced, due to a screen issue, and now I have the 0003 model and seems system % is much lower so far.
I haven't installed any system update yet, so I am on the first original release rom (not rooted yet).
Going to be testing it for a few days before I update and root, so I can make a fair comparison between the original and current oem's.

I think everyone here understands this. the question i think we are trying to figure out is why with similar usage and configurations some people get 40-60% android systems usage while others get 10% over the same period of time.
Android system is way too high.

Yes but if it is configured in an optimal way then android system is always beneath cell standby and phone idle.
For example, today after 15h 28m 23s since unplugged I have...
Cell stanby 38%
Phone idle 37%
Android System.....12%
That is with background processing with auto syncing every hour or so.
I am getting very poor battery life. Fully charged at 8am and dead by 5:30. Hardly even using it. I have a limited number of apps on, just a subset of those on my Nexus One and no rouge ones at all. Made a few calls, no web, a couple of gtalk posts and that is it.
See attached usage screen charge to dead and charging again!
The phone is useless like this... any ideas????
Are you in a building with poor reception? I noticed this issue when I left data on when my company moved buildings.

Is that solid blue bar from your WiFi being on all the time, or is that your awake bar on 100% of the time from a bad app?
That battery life looks atrocious. Show us the second screen to see the "awake" times.

The phone is now changed so, the history has gone! I'll do more screens tomorrow.
I am not sure what you mean by awake bar?
I keep wifi and bt on all the time, as I did on my old N1. I am in the same place in the day as I was with that and will have same reception, which is not bad.

That's it, like I say a sub-set of those on my N1 and all solid apps.
I normally listen to mp3 on the N1, but have not had time on the Galaxy yet, so it;s getting less use.

Other than that, don't see anything crazy... This battery life is really strange. When your screen is using less power than the 'Android OS' it shows you're really not using the phone much, but the phone is still tanking on battery life.
I'll post those screen shots for today when I get home tonight.
A few things I have noticed though. It seems to level off at midday, this is when i leave work and go home for an hour. While at home I will be on wifi. I do not connect to wifi at work.
Secondly, while at work I notice my data often changes between "3G" and "H", while the phone is in the same place. Probably 60% H and 40% "3G". It is not practical to turn "2G" only on, as I get the volume bug and the phone becomes unusable.
I am wondering if the data signal is draining it somehow? If so, how can I work around that? Like I said, I have a N1 before the GN which sat in the same place on my desk every day and had no battery drain issue at all.
I unplugged mine yesterday at 7.30am and it died at 9pm
I used the internet on/of all day made a couple of calls and about 50 texts, screen on time was about 4 hours.
Today i've used it in a similar manner and as of now (3pm uk) 7 and a half hours in its on 57%
The battery in this thing is better than my desire, granted, not much in it but it will easily get a normal user from one sleep to another

I'd say with 95% certainty it's just signal-hunting causing the drain. With my Fascinate at work, I'll easily lose 50% battery within a couple of hours, even if I'm not using it, while at home it'll last me between 15-20 hours before getting low. Easiest solution is to just buy another charger for work, and leave your phone plugged in whenever it's on your desk.
Don't like seeing android os at the top of that list! Does the nexus share some of the problems that have plagued the galaxy s line of phones, the android os bug!? :O

I kind of think you might be right. However, a phone that drains itself while doing absolutely nothing useful at all, is no use to me. I carry it about and am in and out the office though out the day. It would be unworkable to keep putting it on charge every time I come back in the room. I need a phone I can carry around for a working day without charging. My old N1 did. If this can't do it I'll need to get short of it and get something more practical. Seems ridiculous though.
Btw, task killer just got installed by default when I upgraded. All the apps that were on the N1 were installed when I signed in. Just never deleted it
Do you leave your Wifi on all the time even if you don't have Wifi signal available? Don't do that.
If you are too lazy to manage your data connection manually all the time, I highly suggest getting the app Juice Defender from the market. You can save the battery by setting a schedule for data connection and also it will disable your wifi automatically if your phone can't find a wifi spot it can connect to.

Yes, I leave wifi and bt on. I want to be able to do this. I am not asking for it to run for days. 1 full day is all, I have not issue charging every night.
I could look at the juice monitor, however, it does not seem too much to ask to be able to get 1 full day from it of average use. To me, it seems perfectly reasonable to expect the device to work for a full day with all services running.
Is there any tool than can be used to prove that the signal hunting is eating the power? Currently is seem to be in the big pot called "Android OS"??
Well, I'm not gonna defend the phone. Leaving all radio processes on, especially when there is no signal available, is well known to drain a lot of battery since the phone uses more power to search for available networks than when it has a stable connection to one. If you leave it on in a place with spotty or no signal it will make the problem worse.
Juice Defender (the basic one anyway) is free and pretty much manages the connections for you and basically extends your battery life with minimal effort. Give it a go for a couple if days.

+1 with Chrono.... Turn off Wifi completely if you are not using it.
if you are a new android user, you should also check the settings of the phone:
hit *#*#4636#*#* in the dialpad.
this will bring up a menu. there you should try phone (i think, my n1 got stolen a while ago). there, you scroll down and there is a menu to adjust the preferred network mode.
if it's set to CDMA preferred, it will search for a cdma single. you just adjust it (i think) to gsm only. google will help you a bit here.
