Is constantly killing apps bad for battery life? - Nexus One General

I was wondering, if I constantly am killing running process and they are always reloading (voice input, settings, gmail, market, etc), will this drain my battery faster? I'm at 76% with light use from a full charge and the phones been unplugged for around 4 1/2 hours.

That seems normal. mine usually dies within 6 hours, with all settings off. i think i need a new one. under battery settings it says display used 67 % of my battery life and for display time on it says 28 minutes

I've got my display using 73% followed by live wallpaper with 6%.

I mean Display% being higher just means you were actively using your phone more... or you set your timeout too high.
I don't think the actual restarting of the apps uses more battery vs them just running in the background all the time. Unless for some reason they restart almost instantly and you are constantly mashing the kill all apps button then maybe?
As far as your phone dying in 6 hours, that does not sound right at all. Mine definitely goes quite a bit longer than 6 hours consistently. It is currently at 38% battery after 17 hours 24m, with display having used 46% with 55m24s on. Part of that was while it was full brightness when I was outside. I have been at work though so its largely been sitting on my desk. Even when I first got it and was playing with it a ton it went well over 6 hours on a charge.

Some people do seem to have problems with battery life and I can only assume there's a bunch of bad batteries out there, or they are really hammering it..
I used about 25% in 6 hours today from normal usage* and that's even after driving around for half an hour streaming last.fm over bluetooth via 3G.. Sync switched on, wifi off, twitdroid running in the background. The only special thing I have is the setcpu idle tweak.
* Fair bit of browsing, some twitter, the usual 'ooh look you have a google phone' impromptu demos..

What is your display power drain?

Maybe my battery is not trained yet, but so far, on my 2-days old n1, battey lasts for 4 hours (mid. backlight, no wifi, very little use).
Still running stock rom and not planning on rooting.
What I noticed is that in my battery drain stats show Display contributing to 80% of total drain. That's with display being on mid setting... is that normal? What is yours (esepecially for people with stock roms)?
Are you playing with the phone a lot? Like is your display always on? 4hrs still seems extream to me, I am rooted and runninng a custom rom, but even when I wasnt I never managed to get through the battery that quickly, and I use the phone a lot
Here's what I do to get good battery... I only keep backlight on like the a ****as hair..lol barely unless outside...... widgets are cool n all, but if there constantly updating thats polling your battery, live wallpapers are cool, but a battery drainer, I also keep gps, locations and bluetooth off unless using them, wifi also.. also the background applications setting uses battery but if ya want updating widgets no way around that...
Also look in seetings about phone, battery use and see what's eating your battery, I use my phone hours at a time so my display is most my battery drain which is normal, everything else is like 7 percent or less, mostly 2 or 3 percent. ....
I think thats all I do, but you may keep stuff on like widgets and that unfortunately eats battery..
I am running everything in my Sig. I have had my N1 for about 2 months now right around that. After a 14 to 16hr day with some heavy to mild usage I am still over 50%, but then again I have 3g turned off and i am only on Edge all the time since i am always around WiFi. So i would tell you 4 hours is a bit extreme but hang in there it does get better. I remember being around 25% for the 1st few weeks until it got better. Other wise do what Temperbad said that is the best way to go. Only widget i am running that updates every hour is my Weather one. Turn the screen all the way down unless it other wise needs to be up. I am sure that is what is killing your battery. Mine is always on the lowest setting until i am outside.
Sadly I'm rooted, but I will state my percentage too.
Weirdly, my display usage is only 15% on Paul's Desire ROM. Honestly I dont see how this may be - but that is what it says. My brightness is quite high too..
Yeah, I'm well aware about widgets and battery drain regarding 3G and all that, I've had PDAs for quite a while.
For comparison, my old and ****ty TP2 would drain about 30-40% of its battery with same usage that would drain my N1 dry.
I do remember that LiIons get better in a week or so of usage, but I wanted to hear what you guys are getting. Would love to hear from someone who's just bought an N1 like me.
It's under full warranty, so I'm not worried too much. Just an inconvenience.

I have my display set to "Auto Brightness," have a display timeout of 1 minute, have my email get synced every hour, and also use a live wallpaper.
My display accounts for 63% of battery usage.
Auto brightness will use more battery than keeping it low. Cause its constantly checking light density through the sensor to give it the correct lighting...

I agree, but disabling that, disabling GPS, WiFi, turning off 3G, killing all widgets.. ok yeah my phone will last me 2 hours longer, but it's also boring as hell.
Might as well go pick up a simple nokia for $10 - battery will last for weeks, but what's the point..
Not saying your advise is bad, it's a good idea.. just that all these advices to turn everything off - what's the point of even having a PDA then..

I've read otherwise, though I don't think that Auto Brightness is the optimal battery saving setting.
Obviously it's a middle ground between max and low.
Here's a report of my usage today:
~Wifi and 3G both turned on the whole time
~30 mins of MP3s with head phones
~20 mins of 3G tethering over Bluetooth
~40 mins of apps usage (mostly the Browser and the Gallery)
~8 mins of talk time
one 1 min update through the bootloader
have gmail sync turned on, also twidroid syncs every 15 mins
The Battery use app shows:
54% Display (active 6% of the time)
16% Cell standby
14% Phone idle
4% Wifi (active 51.6% of the time)
4% Android System
Right now 14h26' since unplugged, still having 43% of the battery left. The battery meter says 12 more hours until 0%.
All things considered, the battery life is quite good on my N1.
Edit: forgot to mention, the display is set to the middle setting with the Power widget, no auto brightness

Wow... that's some serious battery life.
Ok, some questions..
1. screen brightness setting?
2. how long have u had that phone (battery) for? Did it improve over time?
3. Is it rooted/flashed or stock rom?
4. you got any syncing widgets running (RSS/twidroid)? Live wallpaper?
Thanks a bunch for your input!

Just one comment. I keep Wi-fi and GPS on all day because Wi-fi sleeps when the screen is off and only polls when the screen is on if you're not using it. GPS is only used when your location is required in an application. i dont know why people are always like "you have to turn these off to get good battery life" (Notice wi-fi is 2%)
also i've been running 8 hours with moderate to heavy use (internet, music, phone calls etc) and I'm @ 40%. The drain from 70% - 40% seems to go so slow compared to 100% - 70%.

Sweet, thanks for the info. It seems my battery is also slowly "training" its way closer to these numbers.

Your right... about the updating widgets and wallpaper, they do make the phone funner.. but why need gps on when not using, or bluetooth, or wifi? Just simply turn them on when using...
So much going on with this phone I can say its good pretty decent battery....
Anyone know how to make my gmail sync every hour instead of instantly?
When I got my Nexus my battery was just as poor, but after using it for a couple of weeks I'm getting about 10 hours usage with medium brightness, WiFi, and gps.
So just give it some time and it should fix it itself.

Battery Life??

Hi Guys! and Gals..
Wondering hows your battery life?? Can you make it through a day Ok? I have a touch pro on Sprint and battery life stinks in the worse way.
Last time I checked, it went 13hrs until 31%.
I usually use it for around 90minutes continously reading or web browsing during my commute. There is also 4-5hrs (or more daily) during which I only get 1-2bars of receptions, so it drains battery faster. There was probably also a 30-40minute phone call using bluetooth.
I can go an 10-12 hour day with light use:
45 mins of phone and text (no bluetooth)
20 mins phone (bluetooth)
30 mins misc.
30 mins games.
20 texts.
Data on about 8 hours without Wifi and 4 on (N enabled)
1 hour browsing, emails etc.
30 mins with Microsoft Reader.
Probably a little more.
Also syncing a lot with calendars.
Not bad, but I feel like it could be better.
t-mobile usa.
I have 75% by end of the day
Adjust your PEAK TIMES for ActiveSync, that way your device isn't consistently trying to allocate resources to collect data such as emails.
Screen brightness, system volume, hibernating times, etc.
ALL OF THOSE are key factors in how quickly your battery will be drained. Anything involving the on-screen display is what will quickly deplete available battery life on a single charge. That may seem very "cliche" to say, but the fact is, this device has a 4.3-inch screen, so it's a power hog.
For today, it's been 17.5hrs since I unplugged and the phone has been mostly sitting except for a few occasional brief checks of the phone, 30minute email syncs, and a 15 minute phone call. It's at 40% battery after the 17.5hrs.
It did drop around 20% in the first 6hrs since the phone was in an area of horrible 0-1 bar reception. The rest of the time has been 2-3 bar reception.
17.5 hours @ 40%... are you serious?
My TMOUS HD2 has never gone more than 8 hours on a full battery charge. This is with "normal" usage. Regular email checks, activesync with direct push.
Comming from the Blackberry Bold II with 13-15 hours of battery under normal usage patters, the HD2 is VERY WEAK!!!.
I'm contemplating sacraficing the sleak look of the phone for the extended battery.
Anyone have the ex battery? How's your battery life?

If you need direct push in your life, then I suggest changing 3G to EDGE network.
Difference is quite noticeable.
It sucks,and if you want better battery life don't use it.I returned mine after 48hrs.
All the advice is great,but....
-If I have go from 3G to EDGE.
-Lower the brightness almost to the minimum.
-Set activesync up.....What is the point of having so much technology? if I can not use because the phone dies.
I need real time email and 3G to work,plus all the stupid menus that windows mobile still has made me change my mind.Microsoft has been in the market for a bunch of years and winmo still sucks.
Do not get to impressed with the HD and the movies,cause the thing dies in no time.
Don't buy it and stick with android.
I end the day with about 60% battery life left with mild-medium usage. A few phone calls, some maps/gps, active sync every 4 hours, facebook every 2 hours, weather every 3 hours.
VERY happy with battery life on this phone
i went all day yesterday (my first day with it) so i used it alot, took it of the charger, at 7:30am, and plugged it in last night at 10:00 and it was at 39%. that was BEFORE i turned off 3g(i dont get 3g in my area) so this hd2 blows the iphone battery out of the water....IMHO
my last device was blackberry 8900.
that thing lasted 3 days with moderate use. compared to that, 15 hour limit does suck, and there are times I don't want to use the phone to conserve the battery, which makes rage, but oh well. now I always carry an extra battery in my pocket, so that's a bit better. but that doesn't make it okay.
with the 3g off, wifi off, auto back light,running the energy rom apr 9. unplug on 9 am use about 100 sms and 10 minutes phone call with all the auto data off,just manual check weather and email twice still have 80% after 3pm.
turn off voice commends - this will help
Its getting better
I have recently done a few things to help the battery. I adjusted the the screen brightness to a comperable setting that a friend of mine has his set to on his iphone3gs I did not do anything to the 3g settings or anything like that. I set me email to sync every 4 hours. But my hotmail I just click send/receive and sync it myself. I play music all day on my phone. Check twitter internet facebooks while music is playing and a lot of texting over a hundred sent and recieved daily. Before I made a few tweeks it would kinda die quickly but now it appears to be a lot better.
My batter DOES NOT LAST FOR CRAP!!!!! I took it off charge at 8:13 and at 10:30 i checked my phone, it went from 100 percent to 81 percent. HOW DOES IT GO DOWN 19 percent in 2 hours when i didnt even USE the phone, i just hit the backlight to check the time, this battery is unacceptable everytime i check the phone the percent has dropped

Do you leave 3G turned on? Do you have your e-mail and/or weather checking themselves automatically?
The phone can certainly be doing things that consume the battery, even if you're not manually handling it at the time.
I don't understand why battery life seems to differ so much from phone to phone. My battery life is excellent and I use it a lot. I do have to charge it every night but I expect that from a smartphone. It always lasts me throughout the day with music, videos, calls, texts and web use on 3g. I couldn't be happier with the battery life of my phone.
PLEASE give me good tips how to save battery? BTW im using ENERGY's latest rom with cookie 1.7. i dont understand why i have to stop my email and turn off 3g when this phone is MEANT for these features. theres no point of a having an excellant phone when you cant use its features to its full potentiol without having it die within 10 hours( with moderate use)
Battery is weird
The other day i charged my hd2 fully then got on an airplane all connections were watch from paris with love which looks great on the phone landed after an hour and a half and my battery life was down to 15 percent i think i might have a bad battery when i am in the car i leave it on the charge and when i am in the hotels that i stay in it stays on the charge or plugged into my laptop and thoughts??

Battery drains as fast as hell

My battety lost One percent in one till ten minutes. I alrrady tried to delete the batterystats but it doesnt help. Any suggestions?
Were you doing anything on the phone, when it droppped 1% in 1 to 10 minutes?
regards
Nope. Even in offline mode it drops that fast.
You tried restarting the phone? I'd prolly try a factory reset after that if nothing changes. Other than that I have no ideas.
Regards
I tried restarting, different firmwares, flashing back to stock rom with nandroid. Nothing helped...
How old is the device, and how many times did you charge it 'till now?
I'm on my 4th day since last charge, and standing at 43%.
In anthing battery related, this phone is god.
Hey hi,
I know is frustrating.. but I think we can fix it ..
First we have to figure out what is taking the charge on your batteries.
First check if wifi or bluetooth is turned on. If yes turn it off.
Bring down the brightness of your screen
go to WIFI Settings and turn off the network notification
install Advanced task manager from Market and see the background application. Some might be running as default. But kill all for safer side.
When ever you open an application it stays on the memory u have to kill it using that tool.
OR
IF nothing worked jump into an other firm ware update. I have this android 2.2 i9000xxjp3 Its working very smooth But its an beta version. I am quit fine with that ..
I already did this. And nothing helped.
Similar to my thread:
http://forum.xda-developers.com/showthread.php?t=730302&page=2
Autokiller does not have any effect. I uninstalled all task managing sh*** and I can't find any significant difference.
However, I found after 5 charging cycles it was better than before (now 2/3 day instead of 1/2 day).
okay that's nice 2 know
I got eleven hours... Will see if ut gets better after some cycles. But i rly think its a battery or phone defect.
Hi i just did a battery test on 10 mins of wifi browsing battery drop from 65 and now 60 with 45 pages. Can someone do a similiar test to compare cause i think mine also a flaw set from samsung thnx in advance
How old is your SIM Card?
I know some old cards can drain battery hardly cause there is no power saving implementet, newer have better power management.
Maybe the card is defective. If you can, make a test with adiffetent SIM Card.
Send from my GT-I9000 (I9000XXJF3) using XDA App
The other day, My battery was pretty low, less than 10%. I checked battery usage, and everything was okay. But I made 10 mins of call, and that used 23% of the battery, and that's from a full charge ;
EDIT: current usage stats, from a 100% charge to 31% battery left.
13h 36m since unplugged
Display 31%
Cell standby 20%
Phone idle 14%
Maps 12%
Android System 7%
Voice calls 4% - Time on is 1m 32s. 70/100 = 0.7. 0.7*4 = 2.8%. 1m 32s = 92s. 2.8/92 = 0.0304... *60 = 1.826
So, 1.826% of the battery is used for each minute of voice calls, which means a full charge would last for around 55 mins of talk time. WTF
EDIT 2: I'm using stock European ROM, XXJF3(?)
Do you guys have power saving enabled on the LCD?
I too experienced similar problems with my battery, a single charge did not last more than 17 hours tops. However, since last charge now I have had it running for almost 48h. So what changed?
- I moved to a better coverage area for 3g, but having only 2g on didn't make a difference.
- I disabled powersaving on the LCD
- I uninstalled the widget "Weather from yr"
- I did a full depletion + charge with the phone OFF
After doing this my battery improved tenfold. While I before when checking "Battery History" in *#*#4636#*#* secret menu I had about 80% Running time. THis is now down to 18%. There was nothing before or now in partial wake, which led me to believe that my phone was actually never quite asleep.
So, try what I did, and see if that fixes your problem, it did that for me!
I'll try it. Yes, i rly have a very old sim card. I think i get a new one when my contract renews on a other carrier. Maybe it helps. Thanks fou your help guys.
1 percent in 10 minutes means absolutely nothing. Does your battery fall from 100 to 0 in 16 hours after doing NOTHING on the phone? (equivalent of 1 percent every 10 minutes.) Try this a few times. Check what's using the battery the most. Remember that with any smartphone on the market right now, the more you use the display, the considerably less battery time you will have; so 16 hours on one charge is completely normal if, say, you have 2 hour display on time throughout the day. it's not realistic to expect any better, and don't believe people who say they can go a full 2 days with moderate/heavy use - this really isn't possible unless you have turned off literally everything, in which case it stops being heavy use.

Last time I was checking I had 34 hrs and 11% used for standby. Then I used GPS with screen on full brightness, had it set to WCDMA only with very bad coverage, was taking images and filming, watching video and surfing. I had no taskkiller or juice defender.
I easily get 48 hrs with a bit more moderate use.

Maybe you could enlighten us what your settings are.
My phone lasts no longer than 16 hours. But I also have Wifi, GPS, Bluetooth and Push Mail enabled most of the time and always 3G enabled (because otherwise I would have no use for a smartphone really).

Well, you have the same phone, they both have the same battery, they are both relatively new. If we put the phones side by side and did the same things on them are you really saying your phone lasts for twice as long as mine? REALLY? I'm sorry but through a day of what I would call "moderate" use, battery is uncomfortably low after at most 24-28 full hours (down to around 5%) and this seems to be the case with not just most galaxy S owners but pretty much every smartphone owner - it's very difficult to get the battery to last longer than 24 hours with "moderate" use.
What's your display use time at the end of those 48 hours you have the phone running for?

Just had the best battery life I've gotten with this phone, and here's how I got it

I'll try to keep this short and sweet. I'm coming from a phone that was married to its charger (an overclocked-to-all-hell Pre) and I constantly micromanaged its battery by turning on data, wifi, and gps only when needed. With the Atrix's huge battery and the upgrade in phones I decided, "What the hell. Crappy battery life with this phone is still better than the best battery life with my old one. Enjoy the features." So I left Wifi, GPS, and Sync on 100% of the time. (I did, however, set all my apps to manual sync.) I have 3 homescreens and very, very few widgets. With a normal day's use this usually netted me about 14-17~ hours with about 2~ hours of screentime. Not the greatest, but amazing comparatively to the Pre.
Today I finally took the time go around and start messing with Tasker and other battery optimizing techniques. Here are a few thigns I did that have already netted me large returns:
The first is the simplest: I changed my screen brightness from Automatically adjusting to a static 15%. Though not the best, this is is bright enough for me in close to all situations and the ones where it's not I just change it back to automatic (this is done via the excellent Widgetsoid).
I use Google Voice for texts and that means I always need a data connection--this throws out things like JuiceDefender because it prevents me from receiving instant notifications. Between home and school I'd say I have a WiFi connection about 85% of the time, so i went into the Wireless preferences and turned my WiFi Timeout to "Never." In case you didn't know, a wifi connection is much more battery friendly than a 3G/4G one. Remaining always connected keeps my phone from cutting the connection and then rescanning for a network to connect to several times a day.
I used a Tasker profile I found online (it was either Reddit or Lifehacker, you can probably find it on both) that turns my GPS on only when I load an app that I've specified I want GPS on. I've known about this for a while but I was hesitant about instituting it because a luxury I wanted was to be able to open up Navigation, Yelp, or Foursquare and have an instant lock-on with my location. After testing today, between being generally located by wifi or cell-tower triangulation, and then having an exact location a few moments later with GPS, I found almost zero difference between leaving GPS on and having it enabled right when the app was opened.
Lastly, I downloaded the newest SetCPU here from XDA (it's free for XDA members. Search for it.) and had it throttle back the processor all the way while the screen is off. In addition, it will have the processor scaled back some when the battery reaches 30% and 10% respectively, and a few other instances such as the phone temperature getting too hot.
I'm laying into bed right now and according to Circle Battery Widget I have 37% battery left after 11 hours of being unplugged. Now, while this doesn't sound very great at all I want to specify that this is with my display having been on for 4 hours and 15 minutes. This is by far the largest battery hog (45% in this case) and there is no way my battery would have lasted before I changed these few things. I don't know how applicable they are to anyone else but they sure did help me and I felt I should let people know.
The battery on this phone is freaking AMAZING!! I use my phone a lot! Prior to this I had the Captivate and I would have to charge it around 3 or 4pm cause it was already at less than 15% and dropping quickly.
On 4/26 this phone lasted me 11 hours with lots of usage around 3 hours of display time.
On 4/27 I unplugged it at 10 and it died today at 1am! That to me is sick!! I charge every night so lasting a whole day of use is fine for me!
Oh and I have my brightness at a bit more than half, which I could have never done on the Captivate lol
my experiences have been rather positive as well.
4/26 unplugged at 12am.
4/27 flashed ginger-blur, restored apps, ubuntu webtop mod, all of the other mods.
@6pm i had 7 hours and 16 minutes of screen time and 1 gb of data used. I was at 15%
my only issue is that i only get battery updates every 10%. any idea why?

you need the circle battery widget to get 1% updates. There may be a couple other battery apps that do it as well, not sure.
Ive got a 120 apps installed and get close to 14hrs of battery life with screen on time of 4-5hrs

I'm pretty sure the only way I could get 5 hours of screen time is in airplane mode.
Coming from the Pre ( I still love that phone OS) I can testify to glorious battery life on my Atrix. I don't even charge it at night, I run all day long and charge it usually at my home office desk before I go to bed.
I do miss my Pre. My wife has one and it gives me sad puppy eyes every time I look over at it.

My Battery Research

hi i make some battery "meters" to compare with others and see if we have a bad battery or something its draining our battery. after several test freezing apps, motoblur services and so on i get some interesting stuff like freezing sometimes motoblur service will not help on battery in fact could cause some FC, and not sure if some apps are "calling" the freezing services that make drain faster.
i make a "chart" using gingerblur with apps, fresh sbf test, sbf with apps and so on.
i was using live wallpapers and without LWP, i noticed an maybe "obvious" if you arent in home screen LWP will not drain your battery. maybe only when you wake and stay too much in homescreen, perhaps its not to much IMO yes you can save Battery using a normal wallpaper i can say 5% max.
in my test i use NO DATA, since data will drain a lot the battery and its kind "unestable" to check because bad signal data transfer and so on, i will research more later, in all my test i leave the screen doing nothing i didint execute any process and FULL BRIGHT, and i use Battery Monitor widget to chech 1% by 1%
Using GingerBlur 2.5 in .57 version and all my apps drops from 99% to 63% ( 36%) in 2 hours using LWP in homescreen (secret LWP from SGSII)
After a fresh sbf .83 no apps installed,NO LWP after 1 hr drop from 99% to 88%, after 1:30 from 99% to 81% then i start using the phone and after 2 hr drops to 76%
then i install all my apps,using LWP drop from 99% to 70% then 2 hours later and one phone call drop to 61%
i use this .83 with all my apps 13 min phone call and 2 hours playing a movie in through my tv and drops 30%
and last using a LWP but i was in settings screen for 2 hours and i drop from 99% to 75% again using FULL Bright in all cases
(in airplane mode i get for 9 hour just 6% decrement using setCpu screen off 425)
i will compare this with my 2200mah anida battery (when arrive ¬¬ )
so im wondering who else can try "compare" this results so we can check averages and see if we have a good battery and then a rogue app.
And last i found 1 app that make me drain pretty fast
Enhanced Email (it drops in airplane mode like 7 hours like 16%)
lighflow seems drain a little no to much
My battery drains like 1% per minute on voice calls. I don't know how Moto thinks it gets 300 mins of 3g talk.
I hard reset last night and I'm getting ~3% per hour drain, which is typical for me. Screen time kills this thing no matter what brightness level I have it set at.
Here's my setup:
Blur doing FB and Twitter sync
Gmail set to push
Corporate Sync email, calendar, contacts set to push (setting this to 15 min or 30 min makes no difference in my experiance)
Docs and Voice apps, but not auto-syncing
Astrid tasks syncing with Google
A bunch of other apps that don't sync and aren't running by default (I just installed them, haven't run them yet)
I did a factory reset because something was trashing my battery usage. I burned through a full charge in 6-7 hours yesterday and my phone was quite warm.

yea seems the atrix get pretty warm a lot, in my "heavy" usage playing or watching a video can get 40+ degrees.
i get 1% per hour with no data and like 4% with data.
i was reading heavy usage and get like 24 hrs and i say no way my battery sucks lol.
i usually get like 12-14 hour with medium usage all day data on (maybe 1 or 2 off) posting on fb some browsing msn and like 4 hours playing music
i have 10% bright its enought for me. at least the atrix let me last a little more than my nexus one battery isnt amazing FOR ME perhaps isnt bad at all with "heavy" usage i guess i will get like 9 hours or little less

I wasn't using it at all. I had just power-cycled it so nothing was running (games/movies/etc.).

Lol. I came from Milestone and I am finding Atrix cold .
My Milestone in hardcore use was easily reaching 50 celsius degrees .
My atrix while I am in hard use usually stays in 42 degrees too.
Guys i get a full day out of this phone without even trying etheir you guys are not flashing the phone properly or your phones are corrupted this phone has better battery life than my iphone 4 did
I get at least 2 days. Now that I am not playing with it constantly, I normally get 3 days (and 2 inactive nights) to about 20-30%.
Not rooted.
Do fairly regular email, fb, maps, /. , etc.
No movies
Virtually all data is via WiFi
BUT
It is not my primary computer. I program days and do most of my work on a real computer. Tonight in my chair with a glass of wine, I am using an Eee netbook -- a real keyboard is dramatically faster for me.
And I have developed the following important habit: I always put it to sleep with the slanted key at the top whenever I am done, so my screen time is fairly low. I think this helps a lot.
I expected battery life to be a problem before I bought it and that's why I like the back cover -- easy to change the battery. However, this has even better battery life than my last Blackberry and I thought that was excellent. I won't be buying another battery until I have a year or so on this one.
I believe the essence of all of these power conversations is that if you use it as your primary computer, you will use up the battery fast. If you use it primarily as a phone and as a portable secondary computer, the battery is excellent.

FYI
I'm currently running 1.5.7 & a couple of days ago i froze updater 2.2.1 because i was sick of getting reminders to update (using gladiatrix). Since then (although it only just clicked) my battery drain has been horrid (10% per hour in standby), after thawing updater 2.2.1, my battery drain has gone back to normal (1% every 2 hours in standby)
Mmmmm I will freeze as well to se improvements perhaps there is no updates atm and maybe will not get better
