I have noticed one thing yesterday.
From the moment i had my Rhodium (2weeks ago) i installed advanced Config 3.3 on my Rhodium.
From the start i had the "SDcard power management" enabled.
Since then i had a terrible battery life, 20% loss in 3 hours so at the end of the day my battery was empty.
And did not blame the powermanagement of this.
Trying to locate the power loss i used acbPowermeter.
After two weeks i came till the conclusion that there was nothing which drains my battery.
True out the day i use my phone for just a couple off calls and sms messages.
3G is disabled because the poor reception.
Also auto weahter updates every 2 hours and my mail is also checked every 1 hour.
Bluetooth is always discoverble which does not effect battery drain more then bleutooth off.
Activesync is killed and Opera does realy close and used the nopushInternet tweak.
So after testing al these and more.
Even how much those apps uses de proc.
I had to try one more thing, disable the SDcard power management in Advanced Config 3.3.
And today that config change made me verry happy.
Normaly i start working at 5am and work till 3pm in that time the battery has lost 60% power.
And today i was supprised my Pro II had 91% power left.
So i just want to let you know that in my case the SDcard Power management f*****k up my batterylife.
Specs
HTC Touch Pro II
ROM-Vers: 1.19.404.1 (51489) NLD
ROM-Date: 06/22/09
Radio-Vers: 3.44.25.27
Engergy Info Tab says at 90% battery life:
Last fully charged
23:24 Thu 18aug 2009
Standby time:
18 hours and 40 minutes
Speak time:
1 hour and 4 minutes
Device Use:
5 hours and 4 minutes
I believe these specs aren't that bad because before i disabled the power management my battery would be emty in 16 hours.
So i hope that my findings will help you all.
Bluetooth is always discoverble which does not effect battery drain more then bleutooth off.

Are you sure about that?
in most devices bt in descovery mode drains the hell out of the battery!
I always have my BT ON only, because thats all you need once you devices have been paired.

Hey Faria,
First off all i still love your rom on my old wiza200.
Back ontopic:
As i found on the internet and my findings with the discoverble mode that it is not on all the time.
It only opens the BT pairing when a device want to pair.
After that it closes and acts as BT on mode.
BT does not sends it signal all the time.
But correct my if i am wrong
edit
If i may believe AcbPowerMeter the power drain with BT on and BT discoverble is nill and BT off against BT on is that it isn't a power drainer

ha.. you mean you have it in a timed descovery mode. if that is the case then it is correct.
if i m not mistaking bt on only, drains less than 1% in 24 hours of the battery.
I get 7 hours of battery life and I'm a heavy user. I already have that option disabled. I need to improve this battery!!!
incredible!! your results are great!! any other detailed report, to clarify things a bit?? it would be interesting to have some data to elaborate some statistics and see what we come up with
in your fisrt post, you mean that you achieved the written results at the cost of only 10% battery life, or have I misunderstood it all??? if it's correct, wow!! °_° you have a nuclear battery! from 100% (and powermanagement enabled) I usually achieve 24 to 26 standby hours, 30min calls, 5 hours device usage (most of them connected on 3g). no bt nor auto connections of any kind.
thinking about it, it sounds a bit strange though: the OS is basically the same since quite a long time, and so the management of sd power (I think). so why would it do good (if enabled) on many devices, and not on TP2, having on the contrary such a bad impact on battery life?? I hope my question is clear enough!
since I'm no expert or programmer, I'd really like to have a little explanation by someone who really knows how these things work!
thanks a lot for the contribution, everything that may improve battery life even just a minute is super appreciated! best regards!

Nope my is discoverble the whole time.
About the 1% drain i am not sure, but after i am done with testing we will see how much it drains our battery.

I expect that my testing will be done with in two or three weeks.
Because i want to exclude every possible power drain and drain the battery till its empty to besure how long it takes.
Althought my battery isn't empty jet i will post some screens of the actual battery state.
And later this weekend when the battery is empty i will also post data of my findings.
With my tests i hope to save power and still be able to use the Pro II as its ment to be.
Or else it will be useless expansive plastic brick after 7hours of use time.
At this moment my battery has 43% power left.
And the last full charge was at 4am on 20-08-2009.
So its standby for a little over 54 hours. (current time 11:30am)
In my attached screen it say standby time 49 hours.
I do not know if this standby indication is the actual standby or what is left.
I mean that my Pro still has 49 hours to go.
Think there is a bug in de energy tab, but can not find anything on the NET.
This is what i have done the last 54 hours.
Why is tell you this? althought i am not an heavy user like many people here.
It maybe can help to compare my use with all you people.
- 4am 20-08-09: woke up and disconected my phone from the charger.
- 5am got to work, at work no provider connection so phone is searching for connection for little over 8 hours.
- 3pm got home, so now and then check the weather, play arround with new appz, had to put is some new appointments and contacts.
- Tryed some new reg tweaks, and took some pictures and make a short movie (1.39min) off the awefull weather over here.
- 10pm got to bed with 73% power left in my battery.
- Same story: 4am woke up and got to work to arrive at home at 3 pm.
- Did some checking on the weahter app, added a new contact, tryed some g-sensor games.
- And made two phone call about 10 minutes (not much for the last two days)
- Also send about 12 sms and 2 emails.
- Got to bed at 11pm and woke up at 10am with 43% power left in my battery.
- My mail is checked every two hours, no pushmail by the way
- I used the alarm function as my wake up call
I will let the battery drain completly and try some other possible power savers later this week.
And will post my findings over here including some findings i made with acbpowermeter and what effects background services or programms have on the battery.
At this moment i think i have charge my battery tomorrow morning if it does not shut it self off because of an empty battery over night.
If 4 days standby time is possible with little use then i'm not happy with the power drain.
Why: my wifes Omnia i900 is not used for over 3days (Backup phone at the moment) and has a been standby for 4,5 days and has 50% power left.
Okay i know i can not compare these two devices.
Because there different and we do not use the devices the same.
Later this weekend i will post what i have done and post some data and statistics.
And i will post which changes i made for my new tests week.
What i have done so far,
Energy settings:
-screenlight in battery power is full
-screen goes off after 1 minute
-device goes off after 2 minutes
Phone settings:
-band settings are set both to auto
Bluetooth:
-is set to discoverble
WiFi:
-Did not use it this test
Commanager
-Do not know whoe made it.
but is use the new commanger to quickly switch between 3G on or off.
Because in my area there is a poor reception of 3G
So currently 3G it is switched off
Advanced Config:
-sdcard powermanagment is disabled
-also the others mmc, nand, sim, async, pptp,l2pt
-Data connetions (gprs auto attach) disabled
-miscellaneous (auto daylight savings) disabled
Appz & tweaks
-manilla nopushinternet
-Opera wil close instead of minimize
-Activesync is killed by faking a server
-No2chem 1% battery bar
-Zuinigerijder TouchLockPro
-XDA-Developers GPRS 1 minute auto detechment
Rhodium settings tool:
-Auto rotation is off
-Power special tweak is switched off (next week testing it switched on)
So next week more data and background info
waiting to see the final results!!
btw, what is "power special trick"?? never heard of that.. sounds useful
the more minute of battery life we can obtain, the better!
how do you disable the sd card power management? i want to give this a try. also this is my first post and id like to say this site has alot of useful information!
any updates
I tried disabling and...well maybe there is some little improvement here, but I don't know if it's really because of this or if it's because of different patterns of usage during the days.. mine varies a lot.
as a raw comparison, it went from almost 60hrs standby and 5 of usage to almost 75 and 6 /6.5. both test with phone always on on 3g network, no data connections, no wifi, bt and such. just simple usage (documents reading, editing, tweaking, mostly PIM related tasks.
again, I'm not really sure it's power management related.. maybe V6Maniac did a more rigid comparison, mine's not worth it
waiting for updates
cheers
Palringo
Guys,
I am not a techie so dont flame me if what I say proves to be wrong.
When I installed cleanRAM and when went to the Customized Process List, I saw Palringo as one of the running processes. I remembered using Palringo on the day I installed it, but never after that, which is at least 10 days before. And it stayed there even after a day. Hence I decided to remove the installation and the process is gone now.
Now my batter is really good!!! I had a full charge by 6 pm yesterday and now it is holding at 84%. I did connect to Internet through WiFi for about 20 to 30 mins for skype call, updated weather and stock. Yet it is holding at 84%.
Let me observe it for few more days and let me come back to you if I find anything interesting.
it is known that certain programs are really nasty battery drainer. there's a recent thread somewhere reporting that a (maybe older( version of ESET mobile antivirus did the same. so we have another entry for the black list of abnormal battery drainer
thanks a lot!
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%.

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.

Your phone or battery is defective. Call HTC for a replacement.
Yesterday, I was using the Google navigation on 3G network with the phone connected to a 500mA car charger. After 1hr, the battery dropped 20%...Anyone knows if a 1000mA car is enough??
Tonight, I was watching a Youtube HD video on 4G network (2/3 bars on 4G) with the phone connected to a 1000mA USB wall charger. After 10min, the battery dropped 2%...Well, even 1000mA cannot compensate the consumption of the battery.
The power consumption of this phone is ridiculous. Something must be wrong with the system/circuit design.
NOTE: I'm not complaining the battery but the power consumption of this phone. The charging cannot compensate the usage of the power. Think about a laptop. It's even more powerful, but you can use it freely without any concern about the battery as long as you plug it in an ac adapter. Why can't Epic 4G do this?
man i been seeing the same problems i was listen to the sprint radio while hooked up to the charge and would see it stay at the same percent for about a hr before it went up 1%. this battery issues is making me hate the phone right now and i cant find any rapid charge programs or settings for this yet. cant wait for some custom rom to come out that hopes to fix some of these issues
yup 4g is a battery hog which is why people are complaining about battery life,I suggest you turn it off, it's just not worth it IMO, which too bad cause we're paying extra afterall.

I saw a post this morning. The 3G even consumes more battery on Epic 4G during browsing. so we can expect even worse under 3G.
I'm on my third Epic and they have all had battery drain issues. Battery manufacture dates ranged from July to mid August. Right now actually, I'm streaming some radio over 3g and have an AIM client running in the background and the batter is slowly draining while plugged into the charger included in the box.
I have tried a factory reset just to be sure any apps I installed weren't affecting anything and still no dice. Even with running navigation in the car while plugged into a usb charger the battery will drain about 1% every 5 minutes or so. I'm probably returning the phone for good in a few days
This is with 4G disabled, using SwitchPro widget to enable 3G. I also have background updates disabled(under accounts/sync), I manually do them periodically.

That shoul be more than enough. I use a Motorola-branded 850mA microUSB car charger (quite cheap on Amazon). On a recent day-long driving trip, it was sufficient to maintain the battery level while streaming audio over 3G and simultaneously running GPS tracking. I don't think a 500mA unit would have handled the load, however.
I'm really starting to think this phone is an epic fail. I get from 1.5 hours to 2 hours of use from a full charge! Thats with everything off, 4G, wifi, bluetooth, GPS. The sprint store manager wouldn't exchange my phone because he said their is nothing wrong with it. If it takes 6 hours to charge and then I get 2 hours of use, this phone is worthless to me!

Yeah that doesn't sound right. I think most people would have a hard time making it last only 2 hours. Maybe gaming while running WiFi tether.
Keep in mind with CDMA, the lower the signal to the tower, the more power it takes to keep the connection active. For GSM this is less of an issue. How is the signal where you live?
An interesting side note. I plugged in my charger for my Bluetooth which is only 180ma and it went from 70% to "Fully Charged" in 10 seconds. When I unplugged the charger it went back to 70%. It really didn't like that low power feed.
Sorry if it came out orange. I used screenshot the app and that's what i got. Anywho, its a perfect combo what I've done. See the up time, nearly 15 hours up time. I only lost 35% of life during the time too as you can see how full the batt is.
Remedies: Autokiller set to extreme. ATK: Set to aggressive, with auto kill set to when screen is off. Interval every hour. Cachemate: all settings lit up, so it clears about 12-14 MB every hour or 1-2 every manual clear. Set CPU: Conservative 1000/100 with set to boot. Notice, set CPU resets itself every reboot for now, just make sure your good.
Then you should be good as I have for TWO days on one charge nearly 24 hrs ago.

Sorry if it came out orange. I used screenshot the app and that's what i got. Anywho, its a perfect combo what I've done. See the up time, nearly 15 hours up time. I only lost 35% of life during the time too as you can see how full the batt is.
Remedies: Autokiller set to extreme. ATK: Set to aggressive, with auto kill set to when screen is off. Interval every hour. Cachemate: all settings lit up, so it clears about 12-14 MB every hour or 1-2 every manual clear. Set CPU: Conservative 1000/100 with set to boot. Notice, set CPU resets itself every reboot for now, just make sure your good.
Then you should be good as I have for TWO days on one charge nearly 24 hrs ago.

I would love to see more info/screenshots on this. The one SS you included somehow ended up thumbnail sized only. 2 days is nuts, anything over 24h would be.
hey guys
I've been really happy with the battery life on my epic - I get about 12-14 hours with on-off use, 4G off. My battery is sitting at about 35% after playing a bunch of games for about 3 hours in between classes and it has been running off battery for about 8 hours, browsing the web, sending texts and downloading apps on both 3g and wifi.
I'm using Advanced Task Killer and its set to kill aggressively every half hour - it kills all apps except Juice Defender, itself and LauncherPro.
I'm running LauncherPro - if that matters - doubtful, but I didn't like touchwiz. And I'm running JuiceDefender on default settings. Basically it kills the 3G radio when screen is off unless its transferring > then 15kbs of data. The normal radio remains on for calls/texts.

What is the EVO fix? I'd love to try some extra tips.
My two cents - a typical day puts me at home and at work for the majority of the day and night, which both have wi-fi. I've turned off "look for open networks", "never allow wi-fi to sleep" and I leave wi-fi on. After a full night of charge I took the phone off of the charger at 11am on Saturnday and it finally turned off Sunday at 8pm - 33 hours is pretty darn good, almost two days. However yesterday I took the phone off the charger after leaving work at 6:30pm (so no wi-fi, just 3G) and in just an hour with watching a 15 minute long normal quality YouTube video, a few texts and a short phone call I was down TWENTY PERCENT. What the heck.
Over wi-fi, like I said, I'm good - great battery life since I'm not waking up the 3G radio to do anything. But when I get out of those wi-fi areas that's when my battery starts to drop. Anandtech is getting similar results with awful 3G battery:

Something is wrong with the 3G radio, and I hope Sprint & Samsung seriously do something about it.
You guys are all failing to look at "Cell standby" details.
Time without signal on this phone - no matter WHAT coverage area you're in - is ALWAYS > 50%. This is bull**** and a Samsung software issue. Take a look for yourself.

I never had a problem with but I've been reading many having a problem with "Cel Standby" going out of control. Mine it at 17%. Highest I have saw it was in the upper 30's range after a full day (14hr)
Just an update on my usage from Pg.1:

I am not seeing this issue. Never seen it above 3%. Besides most of the battery is going to the screen it seems. I am actually wondering if it reporting the usage correctly. If the screen was really take that much of the power, it should be lasting a lot longer.
People getting great battery life are reporting they are using task killers and data connection blockers. That isn't even where they majority of the power goes. The system tells us it is going to the screen. Not the tasks or data connections. It seems counter-intuitive.

Turn airplane mode on then off. (settings -> Wireless & Networks)
This will solve the problem until the next time you reboot. You must do this after every reboot.
I'm working on a more scientific breakdown of power consumption. But here are some brief findings.
The highest power consumer is the display. Even on the lowest brightness setting it consumes more power than a normal LCD (I'm comparing it to my Evo). If the display is only showing a black background it is lower power, but then again if all it is showing is noting, it may as well not be on at all. If you actually want to display something on the screen, it consumes power like it's going out of style. So much for Super AMOLED being a power saver (total and completely false.)
The next highest power consumer is the 3G radio. Under similar circumstances (similar signal strength) the 3G radio is consuming more power than the 4G and Wifi radios combined. Wifi seems to consume the least, followed by 4G then 3G. This is crazy and if not fixed might be unacceptable.
Next is background apps, most specifically anything that uses the network (email syncing, social networking and location reporting services like latitude) being the worst. The sync settings on the Epic are not as robust as the Evo and I've struggled to gain control of gmail without just setting it to manual only. Do not use latitude and although some will speak out against task killers, having one to keep "maps" at bay is worth it alone.
Then there are more obvious things like live wallpaper. Or specifically anything using the CPU / GPU and GPS.
More to come, but right now, something must be done about the 3G radio and GPS or this phone could live up to the moniker of Epic fail. I really hope Sprint and Samsung are doing something because otherwise if the phone worked as it could, it would be awesome.
I have epic 4g now for a week. Its still not activated, just sits at home connected to wifi - while I use touch pro2, awaiting sero plus on oct 1st.
There is push sync with hotmail and google. I get home and play almost constantly with the phone from 5 to 11pm - testing new apps/games, reading twitter etc - before I get low battery warning.
My biggest surprise was that the SCREEN (supposedly high efficency AMOLED) is draining more than 40% of the battery! Not the wifi, not the cpu or whatever else is inside. This is with default power managment settings.
What numbers do you guys get in the end of the day? What are you using - 3g,4g,wifi,gps,apps?

Sometimes mine goes as high as 72%, and that's the screen alone, and i have the brightness down all the way to zero (and even at zero it's still plenty viewable).
Definitely the screen is the biggest battery drainer. I've NEVER seen anything higher usage than the Display. Its usually in the 60-80% of battery usage.
And I keep the power to the lowest setting on a daily basis.
The screen is always the biggest offender. Usually in the 70%+ range with brightness all he way down. The samoled talk is just marketing bs. Maybe better performance when the screen is black. Unfortunately all black backgrounds happen to be the minority on websites, applications etc.
Display used to be the main offender on my phone (60-70%) but since I upgraded to DI07, Cell Standby is crushing my battery. The airplane toggle doesn't do ****, had to buy a cable so I can plug it in at work just so at the end of an 8hr day I have more than 30% battery left even with JuiceDefender running. Getting pretty frustrated.

I have this exact same issue. Cell standby is killing my battery. Right now I have 18% time without signal... it has been as high as 25% before. I never had this issue before DI07.
Cell Standby is 41%, with Display at 32%, time without signal is a whopping 50%, and I get near-full to full bars at work and about 2-3 at home.
my cell standby was over 50% after the update. I went in and changed my call setting>System select and chose "sprint only" which will not allow the phone to roam, but it got rid of this battery drain. I have a lot more battery now. But i will have to turn it back whenever i loose service. There's got to be a better way to avoid this thing always looking for the GSM towers when it's a SPRINT PHONE and should for CDMA unless there's no signal. I don't understand how they allow such a dumb issue to haunt tihs phone.
My current numbers:
Cell Standby: 34%
Phone idle: 25%
Display: 17%
Android System: 10%
Email: 5%
Maps: 3%
Dialer: 2%
Wi-fi: 2%
Android OS: 2%
Cell standby has gone up for me since the update, but my last charge was actually the first time I saw any significant "time without signal", and I think that was because I had 4G turned on all day. I have it turned off now and that number is back to 0%.
I'm learning some tricks to keep the battery charged on this thing. Yesterday I managed to go all day from waking up to going to sleep without charging (around 18 hours, though I rebooted at one point so I'm not sure the actual total) and I still had about 1/5 of my battery gauge left.
I've found wi-fi makes a HUGE difference. I have wi-fi both at home and at work, and that's probably 80% of an average day for me. Wi-fi drains the battery *much* less than 3G.
I have my screen turned down not to 0, but probably 2 ticks over that. I use the notification bar swipe to turn it up or down, so I don't know exactly, I just set it to as dim as I'm comfortable with in any situation. Power mode and auto-brightness are turned off.
I switched my background from the default to one that's very dark. I'm convinced that makes a big difference.
I do use a task killer, but I leave my email running, along with whatever else seems like it should be kept running.
Obviously when you look at percentages, there's always going to be *something* at the top of the list, so it's pointless to constantly try to knock whatever's #1 down to the bottom. Different people use their phones differently, so if someone else has their display at the top, it just means they're looking at it a lot and maybe have it too bright. But no matter what you do, something's always going to have a higher percentage than anything else.

How are you able to control the brightness with the notification swipe? I've made it brighter but not dimmer.
Sent from my SPH-D700
So for all the people that have their phone on the lowest brightness, but get a Display usage >50%...are you using your phone that much?
Because I have my display on auto, and my Display usage is a 32%, and that is still enough for it to be #1 on my battery use list.
First, let me get the immature response out of the way: "What sucks my battery? Your MOM!"
Now that that's out of my system, my battery drain is generally caused by the same things as everyone else: screen and TWS. Although I mitigate TWS by using the airplane mode trick which seems to still work for me.

I dunno, I just do. The way the thing works is a little tricky, it seems like it's absolute rather than relative, meaning if your display is already on the dim side, you need to start with your finger way over to the left to take it down the last few ticks. There's only so dim you can make it - the lowest brightness setting would look like a 4 or 5 year old phone at its brightest. That's true regardless of how you dim it. So you may just have it pretty dim and because of the way the notification bar thing works, when you put your finger in the middle, you're making it brighter without meaning to. But if you slide all the way to the left, it'll be as dim as you can make it.

+1 to this, after I changed this setting my time without signal is about 3% before it was up in the 50's. Good tip right there

Does anybody have data from other android phones - nexus, droids...?

3-4 hours of talk time takes up 70% of my use during a 10-16 hour usage. Second would be my screen.
My screen is 79% and cell standby only 7%
My screen is all the way down, even tho with the new update I notice my screen got dimmer than before.

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.
