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..

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 got this app and the paid version, I'm currently at x1.30 useage. How do y'all configure it? I read post from other android users getting way way higher numbers. I just really don't how to configure it(total noob). I have root and got rid of the bloated sprintware. If anyone could post a guide or steer me in the right direction....I would ove you lots!!!

I am fairly new to android and I heard a lot about this app as well. I just let it configure my settings for me. I'm getting around 1.70x right now and its probably my 3rd charge cycle since I got it. It was around 1.30x at first. I got the ultimatedefender exension so it could prefer wifi before using 3g, I think that helps save on battery.
I hope there's other settings to tweak to get the most battery. I would love to go a entire day on this thing.

I tried it a few times on the evo and felt it was not helping me. I didn't believe the numbers it said it was saving me.
on my hero it was incredible with collins battery tweak, as for the epic i dont think its fully compatible as my settings were to turn 3g off with the screen and to turn data on 5m every 2 hours to sync, 12am to 7 am airplane mode. and i didnt notice much on the epic, but then again it didnt shut my 3g off...
Mine currently says 1.74x. I don't think it's really helping though and it's kind of annoying having to pull the wait after I pull out the phone to get on the internetz
im not sure if it is helping either and it gets annoying when i am having a convo with someone on say gtalk and it disables data when my screen turns off.
I used to use it. My favorite thing about it was being able to turn off data while using certain apps/games. Also set it to check for emails every 15 minutes.

I'm getting 2.25x. Install JuicePlotter and run without JD... and you can see your battery drain without JuiceDefender. I've used it for quite some time, and the graph matches my real time use (I've also used other battery monitoring apps and seen the same kind of results, JP just shows it in a nice graph). Then install JuiceDefender (I'm running the beta channel) and watch how much more slowly your battery drains.
When ACS released the latest SyndicateROM with Froyo I jumped on it and disabled JD because my girlfriend saw her battery lasting a LOT longer once TMobile (she has a Galaxy S with them) released Froyo. While it was better, it's ridiculously better with JD.
It will auto configure itself... but I customize it and have it disable during the night, 30 minute data off during the day, configured the apps I want (and yes, disabling data when using a game is a great way to save if you dont need data during the game).
Im at x2.14 now, self customized using JD Plus. 3G/Wifi turns off during certain apps running in the foreground, 3G/Wifi is off when the screen is off, Wifi automatically turns on/off depending if Im home or not. Best $1 ever spent.
I'm using super power, and JD and will be testing out, I'll let you guys know!
On custom. Data turns on every hour and during the night, data is off from 1:30AM to 8:30AM. Data is only activated after unlocking and ignores on low battery below 15%.
Everytime i use this app it starts ****ing with my permisiions and ****s up the phone i finally just said screw it. Its horrible.
I own Juice Defender Ultimate. I use the beta and It says I get around x2.35 on average. I use Advance settings and set them to my liking. I spent a week where i tried one day JD and next day no JD, same process the whole week. ended up as 30-40% more battery with JD.
I'm currently on the CM7 ROM, I have juice defender and done all the minor tweaks as far as disabling wireless network location, turn off the wifi and GPS, and an app killer. I still only manage at max 9 hours before my phone tells me to recharge.

Yeah, I need some help too. I get about a day and a half with no use at all, and about 10 hours with minimal use. 4 hours with real world usage... I can't deal with this. Could it be the battery? It performs like a 1 year old, used, refurb battery came with a stock phone!

Have you configured the battery since flashing the rom?
I get decent enough battery life, with light usage I can go about 36 hours w/o a charge but on my heavy usage days I usually have to use the car charger a few times a day.

all of these... biggest one is to turn off data when the phone is in your pocket. use wifi when u can, avoid using 4g unless plugged in, configure the battery in recovery (i've actually notice that this helps less than anything else for me), and finally: get an extended battery. it's worth the extra hours u can squeeze out of it. don't expect more than 4-5 hours screen on time with any rom/kernel/modem combo with a stock battery.

Yeah I also did that wipe battery stats at recovery.
I just thought maybe my expectations were too high, although it seems as if my battery drains drop pretty fast.
I would say about -10% battery drop every hour, just checking the time and send/receive text messages. Occasionally I surf the Web on the phone when on break at work. Other than that the phone is in my pocket, and after my 9 hour workday my phone demands the charger.
This is with the stock battery, so I guess this is normal unless I'm using the extended battery?

u could also run a kernel that allows for over (under) clocking/undervolting. that helps some, too
get the duricell portable battery extender, add milliamps to your arsinal in one way or another with extended batterys or whatever, if you call sprint and complain loudly and dickly they will rebate you the cost that u spend on a new battery or batt extender whatever... that being said all the above options work great, u can also use night mode on chainfire 3d to save battery, or perhaps half your pixel rate, or perhapes turn off some colors (havent seen an app to do this yet) and reset your battery memory in cwm, kill ur batt, charg while off, then cycle again like that. (theres an app for that) if your not rooted, root your phone. if you dont want to root your phone, cycle ur battery the old fasion way or pop it into a rooted phone and do it.
I used to get really poor battery life (due to my phone not sleeping as evidenced by Spare Parts app). I rooted, used Titanium Backup to freeze various apps, and got an Zboost antenna booster for the office and called Sprint who sent me an Airave for the house. I wiped battery stats and cleared my Dalvic cache and the thing the finally got me right was finding out the Amazon MP3 app was still logged in though not running. Once I made sure I was logged out of that and Lattitude (Google Map feature) and Facebook, I haven't had any problem with a sleeping phone. Stock Froyo, standard battery, but rooted. When they say a bad app keeps your phone from sleeping I think they mean an app that requires log in...although this does not seem to be a problem if you stay logged in from a browser, only from an app!

You may be shooting yourself in the foot with some of those things. App killers aren't that useful on Gingerbread since they keep killing apps that just reload on their own, and every time the reload it uses power. Just because an app is loaded doesn't mean it is running. Try letting the system take care of it. Juice Defender may help a little but it keeps shutting down data and starting it up, which means you don't get as much usefulness out of the phone and may waste power in some circumstances.
See what you have set to sync. Turn off any autosyncs you don't need, like weather screens, facebook, etc. If at all possible set them to only sync when you open the program.
I use the exchange option for gmail using the stock samsung app, which gives me push email but doesn't have to keep polling the server. I don't know if that makes a difference compared to imap, but it works well for me. don't think you have that option in CM7.
Wifi is a much more efficient way transfer data than 3G, use it whenever you can, and set it to never sleep. Otherwise the 3G radio keeps starting up again and wasting battery.
You can freeze the DRM stuff if you don't use it. I don't know if it really makes a difference but everyone thinks it does, so I do it.
Having a black wallpaper helps a little because on a AMOLED screen a black pixel uses no power.
The biggest battery killer is being in a bad signal area. If you always have 0 or 1 bars then your phone is going to always be draining the battery trying to find a good cell. In that case Roam Control may help you.
That's about all I do, and with the latest Stock gingerbread EH17 and EI22 I'm sitting with about 40 to 50% left after 12 hours, that's with light to moderate use.
I've been through the ringer with this. I'm pretty comfortable now, routinely managing to have 33% of battery left after 12hrs w/3g always on, sync always on, intermittent music listening, 2.5-3hrs of gaming and general "screen on" time (auto brightness), 1.1 GHz OC, no undervolting, and GPS always on. Here's what I'd suggest:
Flash a ROM w/ NO CIQ (thanks k0nane!) - In addition to being a leech on your privacy it's a leech on your battery. It's old news to long-time Epic owners at this point, but ditching CIQ improves battery life and overall responsiveness of the Epic. A popular stable Froyo ROM for this is SFR 1.2.
Minimize always-running services - Long press your homescreen, select "shortcuts," select "settings," and select "running services." Tap this to see what's running ongoing services (not apps) your phone is running. All of these are drawing current to stay in RAM. Things like Juice Defender, Tasker, and others show up here and draw power in doing so. JD and Tasker especially can drain a lot because they perform constant tasks as well. Uninstall them and let your phone manage itself.
The same goes for task managers and app-stoppers - Froyo and above does this fine on it's own
Freeze/Uninstall system services you don't use - This includes things like Sprint voicemail, the "Email" app, and the "SprintAndroidExtension.apk," and SNS services. You'll most likely find these on the "Running Services Page" as well. You can Titanium Backup to uninstall them, but I recommend the SDX Stock App Remover as that can restore them (TB can't reliably). TB can freeze these as well, which accomplishes basically the same thing. SNS is connected to Facebook, so if you use that a lot you might want to keep it. DRM services can also be removed, but may cause problems reading the SD card. I stay away from it.
Use Spare Parts to monitor wakelock and CPU usage - If you notice something giving you persistent trouble, shut it down. This is time-consuming, but you'll get a good feel for what apps are out there to accomplish similar tasks and which one best suits your needs.
Uninstall apps you don't use - Next time you wipe and flash a new ROM, reinstall or restore backed up apps as you need to use them and not all at once. You may find you don't need quite a few of them, allowing you to keep more space open on your phone and requiring less current to maintain them
Don't charge the battery overnight - most phones can reach capacity in 2-4 hours depending on charge level. Beyond that, holding at or around fully charged will degrade the battery by denying it the ability to release the stored energy. I charge mine in the evening a few hours before bed and top it off in the morning before leaving for work.
Get an 1800mAh battery sold for the Epic Touch - this is what moved me form "getting by" to "definitely comfortable." For around $25 (incl shipping) on ebay, I've gotten a new lease on my Epic's life. It may seem like cheating to bring in a new battery, but it makes a lot of difference WITHOUT adding more bulge to your phone (makes it a tad heavier though).
Hope this helps. Remember, of course, that what works for one phone won't necessarily work for another. Despite being the same model, minor imperfections in silicone can create individual temperaments for each phone.
I as always trying to make my battery last by stopping this and uninstalling that. Then I thought; why did I buy this phone with all of these capabilities to turn them all off
So, something like the "Hyperion Sprint Samsung Epic Touch 4G 2 x Battery + Charger" (too "young" to post a direct link)
Would fit in/work with the Epic 4G (without needing a new cover)? Even though its for the Touch?
Lol, I've been doing many of the suggestions across the board, and have gotten much better results. But I'm still not "comfortable" with my battery strength, especially when I'm unable to charge my phone all day...
Looking into your running services is a big one. week ago my battery life greatly decreased. I kept seeing market update pending and it wouldnt go away. Never update never go away. I manually updated the market and the battery is back to wonderful. It drops 2-3% at night off charger. Thats about 8 hours.
A sticky with all the main running services and which ones you can stop would be wonderful. I have sns services running. I think i can stop it but not positive. I also have sanservice running supposedly some type of samsung update. Its not doing anything but its been running for 2 days. No negative effect on battery(that i notice) but its running. Also make sure you turn location off. Ive also noticed that even when you back out of google maps its still in running services. A restart fixes that but thats annoying.

SNSservice is a Facebook and Feeds and Updates Widget service. ALWAYS stop it. It does not matter to Facebook, even if you use it, but if you remove the Feeds and Updates Widget on one of your screens, that service continues to search for it and will kill your battery in a matter of hours (it starts a "restarting" loop). Either leave the widget on or kill this service after every reboot or if you are rooted, freeze it along with DRM service.
My other battery tips are to log out or sign out of every app such as Lattitude, Facebook, Amazon MP3 (it's ok to use them, but don't just back/exit out, actually sign out of them so you have to log back in next time). Apparently, staying signed in causes your phone to not sleep and you can't find what is causing it (i.e. you can't see it "running" anywhere...people call it a misbehaving app, and you would have to delete apps one at a time to find it by trial and error).
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.
App installed are not strange at all;
Adobe Reader
Android Task Killer
AL Voice Recorder
Amazon MP3
Astro
Google Authenicator
Compass
ConnectBot
Currency Converter
ixMat Scanner
RealCalc

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.

When clicking on the graph, there is a blue bar showing how often/when the phone is "awake", like in the screenshot I've attached.

do you keep mobile data turned on? if so, do you keep 3G turned on, or just 2G?

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

No, it's strange you have a task killer on Ice Cream Sandwich. WTF? This isn't Eclair. Get rid of the damn task killer.

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.
