Only had the phone for two days so this should improve even more:
overclocking to 1.4ghz, under clocking when screen off to 0.3. 9 hours screen off, didn't lose a percent, still 100 on desire Z. EPIC!
thats good to hear ! Cant wait till i get my hands on it! damnit ! 5 or more days togo
Did you have any other functions enabled? 3G/WiFi? Sync'ing with FB or Twitter apps? Anything like that?

how many hours can you get out of it when you are using it throughout the day, e.g. email, internet browsing, twitter, bit of music and phone calls? using data and wifi?. Im on my 5th day and averaging about 14 hours, hoping that the battery hasnt settled yet, otherwise my hope is for the NAND being hacked and roms for optimal performance!
Do you actually get more real-life performance out of the overclocking (snappier menus, faster app launching), or the only place where it shows is the benchmark? Is Sense faster, or is the difference not visible (0.8 vs 1.4)?
On the other hand, underclocking could be really useful to preserve battery. But doesn't the processor underclock on its own when in standby (by design), do we need to use 3rd party apps?

contrary to what you should expect,
overclocking this SoC just hightens the clock's max roof from 800MHz to 1GHz, 1.2 or 1.4GHz, not the "permamnt" MHz count,
because it auto-fluctuates and adapt depending on usage
AND with the SetCPU app (which I assume JupiterDroid is using),
cycles per second can be optimized even more.
The phone won't go up all over the way to 1.4GHz when idle, but will maintain a very low cycles per second clocks, thus improving battery life
Here's my experience w/ battery life and overclocking the Desire Z (for today).
I only have it set to overclock to 1GHz and I have typical SetCPU profiles to underclock to 245MHz when not in use.
My phone has been off the charger since 9am (5.5 hours) and is sitting at 92% battery power. This includes permanent connection to WiFi (no sleep policy), receiving updates to email/gmail and some text conversations with Trillian and a 15 minute email (composed w/ keyboard).
Compared to my old HTC Hero (Running VR 1.5.0), this is a huge improvement, though with VR 1.5.0 I could run JuiceDefender & have similar battery life with the right profile setup.
Yup I even notice better battery life in actual use. My friends were running youtube and doing web searches like crazy on my phone last night + games for a good 5 straight hours and the battery was holding up well.
I've got to say, the battery life on the Desire Z is outstanding... 18 hours with light use and battery still @ 92%!!!
What about 1GHz core compile?

are you using set CPU and overclock?
Is anybody getting time without a signal percentage in the cell standby item in the battery usage? Im getting 12% sometimes more and im getting about 14 hours battery life with moderate use! I dont feel im getting the best out of the battery and worried this might be part of the issue!
Hi guys.. sorry for the novice post.. i have had my Desire Z for a day and am interested in overclocking it - but
a) are you saying it possibly INCREASES battery life?
b) is the speed diff noticeable in day to day use - or just benchmarks?
c) How do i overclock - what is SetCPU and how does it work?
I don't think my battery has settled yet .. I hope not anyway, and I just (temp) rooted and overclocked to 1Ghz last night, haven't tried higher yet because I feel like my battery is kind of just disappearing so far, none of this epic "all day and then some" stuff some people are reporting. I think it may be that fact that I've been using the device pretty sporadically so far, and it hasn't had a chance to settle.
Also "cell standby" seems to be using a lot of battery, and I'm thinking that's because I'm unfortunately in a spot where I get extremely poor to no coverage most of the day. So I'm thinking the cell radio is using a lot of juice trying to get that 1 bar I sometimes see here. There didn't seem to be a way to easily disable the cell radio without disabling wifi though, until I found this "airplane mode wifi tool" on the market which I just installed.
So now my cell radio GPS and bluetooth are all off while wifi is on, hopefully that will make a difference. I'm wondering if using 802.11n is more draining than 802.11g also I know both my router and the desire z support N but "network info II" reports I'm only connecting at 65Mbps, while my laptop connects at 150Mbps.

I don't think there's any way overclocking can actually increase battery life, but managing CPU speed with SetCPU seems to be more effective than the default behaviour for some reason, so the fact you're overclocking when using it but underclocking when not using it results in longer battery life. I'm pretty sure it does regulate the speed automatically without setCPU but maybe it doesn't clock the CPU down to absolute minimum by default when the screen is off?
Anyway the noob friendly guide to overclocking by JD is on the forum with an [INSTRUCTIONS] tag.. I can't link to it apparently since I'm a noob.
Edit: Added link ~TheRomMistress
Thanks guys. Main thing i'm curious about is whether i just install SetCPU or i have to "root"
Yes, SetCPU needs root access.
Still trying to figure out how the OP is underclocking to .3 using SetCPU.. Lowest I can go is 245..
Unless I'm an idiot and completely missing something.. I'd love to turn this phone way down when the screen right off. As it sits, I'm lucky to get a full day from a fully charged battery.

Your mileage may vary
You can check by yourself and then uninstall if you are not satisfied (or just reboot and changes will dissappear, since we don't have permanent root yet)

First off Happy Thanksgiving to those who celebrate it.
Ok so i am wondering a couple things. I have an HD2 with one of Mdeejay's blends on it. I use launcher pro so looks aren't really gonna change too much. currently I am having huge battery drain. I'll charge over night and cant seem to get past 80%
1. Which Rom is the best on battery power?
2. Are there any underlying things in WINMO that maybe I should turn off before starting android?
3. Are there any underlying things in my android build that I can turn off?
4. My task killer seems to always get full even when I don't start certain apps, is there anything I can do about this?
Thanks to all that help.

1. Some roms may cause problems, but all compatible ones shouldn't have influence on battery life. It's just hit & miss, try the one MDJ suggests. (probably mentioned in his thread)
2. There are some tweaks available yes, I personally doubt they work though. I get good standby battery life w/o even having looked at those tweaks. Just search for registry tweaks on this forum.
3. You can always turn off mobile data, sync, 3G (and obviously wifi, bluetooth, and low screen brightness). Install setCPU to underclock your processor (again, there's a lot of informative threads on this already)
4. Uninstall your task killer and never think about it again. They only do evil on Android. Having apps in your RAM memory is now actually a good thing, as opposed to windows. (yet again, a lot on this can be found through search.)
About the max of 80%: your battery isn't calibrated well. Either search for batterystats.bin on this forum and you'll find a guide on how to recalibrate, or reinstall your android build with a 100%, completely charged battery. Check the percentage in WinMo, and then leave it turned off for half an hour to make sure it's reaaally fully charged.
Completely agree with the above, with the exception of SetCPU. You're far better off with a recent kernel (I'm having great success with MDJ S6.1) setcpu is pretty much redundant now unless all you're interested in is melting your processor with ridiculous overclocks and pointless benchmark scores. ("Oh look I get three more points in quadrant than you but my phone reboots every 15 seconds")
After I performed my battery calibration I get two days moderate use out of my phone with no problems.
what if I were to charge to the full 80% then re-flash wouldn't that make it so the battery is 100%... also if i can only get 80% I would think that a flash at 80 would tell my phone it was 100 when in actuality it was 80. Maybe I'm confused about the whole battery conditioning issue.

You might want to read my post again, I suggested to install setCPU to underclock the CPU, to improve battery life. I don't quite see the point in overclocking either.
I updated to the current build, using the samsung tool to update when it came out. I've never rooted, so I have always been stock.
Wiped it, and then went through their whole process to install.
My system shows im running 2.2.1, so I know I did it right.
My question is, Froyo is supposed to have improved linpack scores by up to 5x. I used to get like 8 mflops, and now I get around 13. That is by no means 5x more. Is something not working right? Are other people getting this result?
Next, my battery life is horrible, well much worse then before. While running 2.1, I used Zeam launcher, and had Advanced Task killer set to auto kill everytime I turned my screen off (with the exception of a few apps I used). I would traditionally be able to get like 16 hours of battery life, and still have like 30% battery. This is with texting and web browsing during the day. Now, with minimal texting and less use, ive been getting like 12 hours, and im at like 5% battery life. As far as I know, I have it set up just like I did before. Anyone else running into this at all?
(most of my battery is being used by my Display 89% right now, or so my phone says...)
Maybe I am completely offbase on these, but I want to know if anyone else is running into these questions. Any suggestions would be appreciated.
I am fairly new to Andoroid so take it for what it is worth. I am also experiencing a drop off in battery life since Eclair (which was also no great shakes re. battery life, lasted about a day), and did the requisite things necessary to to extend battery life - screen at lowest setting, no automatic sync, wifi/BT/gps off when not in use. In my case, the hog is display (98% ) which I attribute to spending more time with the phone since Froyo update. In my previous phone, a blackberry, it took several days and a few battery pulls for the OS to completely "settle in" - I don't know if that's the case with Android OS.
Five times!
Where did you hear that? People with certain phones saw close to a 2x improvement because of JIT, but JIT isn't optimized for our phones so it doesn't do as much for us. Personally, I think a 50% improvement with only software changes is pretty impressive.
Also, don't use task killers with 2.2. FroYo has better task management than eclair did. And people who have tried using task killers to improve battery life have reported worse battery life than just sticking with the stock memory management.
And you know that since your display is using almost 90% of your battery, the problem isn't a runaway process. It is more likely that the problem is how much time the screen is on. Get spare parts and tell us what percentage of the time since last charge/boot the screen has actually been on to use so much juice.
Battery could be the TWS (time without signal) bug. Go to Settings > About phone > Battery use > Cell standby. See what your time without signal is at. If more than a couple percent then toggle Airplane mode on and off. Also make sure you update your PRL. You may have to do this every time you reboot. My understanding is that it's a common problem with 2.2 and CDMA devices (not just the Epic).

Yeah,
<http: //developer.android.com/sdk/android-2.2-highlights. html>
Says 2x-5x. I seeing as i'm not even getting 2x, thats kinda a joke.
But something within the update had to have affected the screens battery use. Like I said before, I had fine battery life not 3 days ago, and now it all of a sudden drops. I HIGHLY doubt that that is a hardware issue. I can test, but I have worked with computer hardware for years, so that just doesn't make any sense to me.
Linpack does not execute any code..it does a floating point calculation..wit JIT you get up to 5x efficiency in code execution..does not mean it crunches numbers faster 5x faster..
The phones that are achieving 5x or more speed are doing so through a flaw in linpack...
I just can't seem to crack the battery life conondrum. I've calibrated (charge to 100%, wipe stats, then full cycle).
If I'm listening to music its consistently I'm sucking ~10% an hour, if idling ~4-5%. Which means I'm getting around same battery life as my old nexus one – mediocre, I end a working day with around 30-40%. If I want to go out after work i have to remind myself to charge during the day...
Right now I'm even running a mild setcpu undervolt (with faux123 kernel) and profile (screenoff max cpu 600mhz) but seeing not much improvement if any.
I am on gingerbread AT&T radio so thats not it either... any tips aside from 'use juice defender' (which I don't want to do as I want always on data instant push etc., I know juice defender basically shuts your data radio off)?
Note this is the same with stock gingerbread as well as the ROM and kernel I'm currently on (redpill, faux123 kernel)
I've done everything you have and i'm on a Bell Atrix....i have been looking into this for about a week or more and i just can't crack it either!!! it's driving me nuts and i have spent sooo many hours googling, searching xda and other sites and have tested MANY different methods and still can't seem to figure it out. For me i know its the phone idle...but what it is i can't tell, i have SystemPanel monitoring as as well as watchdog which i alternate with. Flashed the battery calibration fix and calibrated the meter blah blah blah....driving me nuts and i know its not a faulty battery because before i unlocked and flashed 2.3.4 i could get about 30 hours with heavy to moderate use!!!
For the love of god i wish a team of dev's would look into this!!!!!!!!
Honestly none of the faux kernels worked for me... Try gobstopper, stock kernel with watchdog was the only combo to give me good battery life. Not to mention lock sounds works properly, and its fast. All bell users should use it. Seriously... 19+ hours worth moderate usage.
phone idle is still high but it seems to be a slow drain.
Sent from my MB860 using XDA App
a.) not an option for me, AT&T phone
b.) I'm not seeing faux's kernel do any worse than stock kernel, I don't think its the kernel?
c.) yeah I tried system monitor as well, the highest process was opera at 3%.... 3 lousy percent lol
1. Calibrate your battery again (I have posted a guide in the General section)
2. Flash a kernel which allows overclocking, install SetCpu, add battery saving profiles (downclock to 500mhz on screen off, downclock to 800 mhz when battery less than 30%, downclock to 800mhz if temperature higher than 50C)
3. Freeze all MotoBlur bloatware (there's a guide in the general section)
4. Disable data and wifi unless you need it
5. Install Watchdog and set it up according to instructions I provided in my calibration thread.

Well, if you keep data or wifi turned on at all times, then there's no way you can have something more than mediocre battery life, sorry.
It's not the Atrix'es fault, its the brutal truth with all modern smartphones.

it is not a kernel issue, i simply dont know exactcly what hack in particular gives ninja the amazing battery life. but im working hard to determing this so i can share it.

The people in this thread have listed all known steps to improving battery life.
If you really follow all of these guidelines and have bad battery life, you might want to try a battery replacement.
If you are sure your battery is not the problem, you might also want to try a couple of custom roms. Who knows maybe you will get lucky with one of them.

Is there any way to log off from motoblur once you are in so you can stay offline? Of course any connection that gets cut will increase battery life.
I don't understand all these battery life problems. Its got to be an app you are installing or your battery is buggered!
Admittedly when I first installed 2.3.4 OTA, battery life dropped like a stone, but I drained it flat, and then charged it up again and its been fine ever since.
I'm running on stock 2.3.4 without root, and I have quite a lot going on (IM's/Facebook/Twitter) and I can last well over a day and a half with moderate use, this includes sms and calls.

Battery life is a very subjective issue. One person might be fine with the phone, while the other person will say battery life is terrible with the very same phone.
Besides the obvious drainage problems, it all depends on how you use the phone.
Honestly the best thing that worked for me was turning off "Syncing".
I currently have 3G on, BT on, ETC...
Syncing in the background killed my battery life. Now I usually make it through the day without the need for a top-off...

Im in stock gingerbread and battery life is definitely worse than on stock 2.2.2 and and im basically running the same Apps. I am a heavy user and I used to drop 10% per hour. Switch on at 7am and by 5pm I was changing battery. Now I am switching around 3pm.
That's why I have 3 batteries!
I still think its better than nearly every other device I have owned but that nay be because battery is larger. I dont know why they don't design to put in 2400 mah batteries (my treo 650 had one!).

The treo 650 also had a thickness double that of the Atrix .
The batteries in your phone are high-capacity lithium-ion batteries. This kind of battery technology cannot be simply reset and “re-calibrated.” When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently. By deleting this file, it basically wipes the phone’s memory on what the battery can really do. This actually does damage to your battery by using up valuable charging cycles, all while giving a fraction of battery life and performance.
Now, you might be saying uh-oh, I’ve already re-calibrated my battery! What do I do?!
Well here’s your answer. Use your phone like normal. Yes, your battery and phone wont perform as good as it can for a while, but after a few days, you will notice that it starts doing better and better. Give it time, its trying to rebuild all those logs that you just deleted.

This is the first time I am reading this sort of opinion, though I have read countless info on the subject.
If you want to make such a strong point, you better have source to back up your opinion (article, studies, other source of proof, etc).
These threads are all USELESS without NUMBERS.
Like another person with common sense already stated in this thread, you need to provide numbers.
GB has this improved tool (over 2.2) where you can see how your battery is wasting its juice. Watch those numbers for a few charges and then POST THEM TO COMPARE.
Saying your battery sucks without giving any numbers is like calling a color ugly.
(just in case someone misses the points, without numbers it's hard to compare, since it mainly becomes an opinion at that point)
P.S.- Please don't post "My battery lasts for over 9000 hours." and think that's enough info. Use your head.
Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.

He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.
PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Think about if your screen was on while the device was awake..your time would be cut in half

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.
Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Something we can all get behind here... I remember I used to get 24+ hours on froyo w/o customs kernels. Le sigh..

1. CM9, although i think aokp does better.

-CM9 still seems cleaner, but AOKP seems better.
ÜBER™ said:
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.

3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.

-I don't use the supercharger, but I do apply the same oom ram mods. These help close unused apps when they exceed the applied limit. Based on my experience, it's kept apps under control.

4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.

-THIS +9000! An app that spends all of it's time stopping other apps is wasting just as much "battery." I maintain, Advanced Task Killer, with NO, I repeat NO AUTOKILL. Set a widget on your home page, tap it occasionally to make sure everything is closed. Same effect as the built in task manager, but one single convenient tap.

-These numbers are pretty much the same for me. I almost always average 3 hours display on the stock battery between games and internet. 5-6 hours on the 3500, but I'm pretty sure it's not reaaallly the 3500mah it claims to be... . I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

I don't turn off my connections at all and get great battery life... and seens how the op states don't say anything about disabling 3g or anything id say your comment was the least helpful on the thread... but at least you tried... don't get into a battle of witts with me, I'm afraid your unarmed...

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.
Please follow the format specified by the OP. List the 7 items. Bickering in this thread will not be tolerated.

Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.
- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Using AOKP with shadow kernel.
Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.
