I'm getting bad battery using my phone. Can you guys recommend SetCPU profiles or settings, or do I need a new battery? Thanks!

In case you've set a min/max something like 19 (min) to 768 (max), try setting the min quite a bit higher, like in the 200-400 range. See if that helps. Also, don't go crazy setting a whole bunch of profiles. In fact, for troubleshooting, don't use any so you can narrow things down.
245 245 works really well and doesn't make the phone take forever waking up

Not specific to this topic, but I suspect you really see much difference between 806 and 604...
For your screen-off profile, change the min to something like 245. Just try it for a day or two and see what happens.
I too have poor battery life. We're talking down a percent every 2 minutes. I'm running the Droid does rom. I'm gonna try your settings and see how that works.

My battery drains fast too. I stopped using setcpu. When I'm not using the internet I turn it off. Now my battery last a lot longer.

im at 710/844 2**/4** with half decent battery life. but i do stil walk around with a charger
getting linpacks of 5.783 @ 844mhz!
Well a lot of you have seen my posts on this subject but the op asked so...
I have no setcpu installed, no autokiller. The Froyo ROMs are default set to 710mhz and I enable JIT as it helps battery life. You also NEED to calibrate correctly to see best battery life.
CGriffiths86 summed up my long winded version of battery calibration like this...
1. Fully charge the phone
2. Shutdown, boot into recovery, and Wipe battery stats
3. Reboot from recovery and use the phone as normal until it completely dies
4. Fully recharge the phone
With battery cal, no setcpu, and no autokiller, I get 27-30hrs on a full charge with solid use all day including bt music playback, navigation, calls, texting, and minimal web access.
The other settings I use are.
VMheap 24
Screen at 35% brightness
N2...
What about the other 2 settings with JIT? Do you have them checked or unchecked? Comcache? and Dithering?

I dont use compcache (although I have read that it works well with FROYO based ROMS), and I dont enable surface dithering (doesnt add that much crispness to the display to me and takes away from processing power). I dont believe either of these settings will have much impact on battery life though so try them out and if things are still as snappy as you want then MPTY.
oh yeah try turning off auto sync it helps me a bit
Using CELB 2.8, I get about 24-30 hours of battery life with a fair amount of usage.
http://www.techradar.com/news/phone...android-battery-life-should-last-a-day-690439 when Page made this comment, I was at the time convinced that my phone itself was to blame and quite incredulous with regard to his statement. Turned out...he's right, at least in my case. I'd say stop looking at OS settings and focus on the apps you have installed.
I was having absolutely terrible battery life, even with this rom (though at version 2.5 or so), and couldn't figure it out for the longest time. The culprit turned out to be NewsRob, an RSS reader that syncs with Google Reader. I had it initially set up to sync every 4 hours or so, but the default is 1. Somehow, thanks to Apps2SD, when I flashed a new ROM, the sync settings reverted back to the defaults. I finally figured this out and changed my settings to manual sync and battery life has been epic ever since.
Another app that I think was causing some drain was Locale, as it's constantly polling your phone for data about its condition. I stopped using it altogether and am just out the 6 bucks, I guess.
And another thing that helped was completely removing AutoKiller from my phone.

This is gotta help a lot, thanks! And thanks to the other guys for quick replies!
With a full battery in the morning, o usually have about 20% left about now which is 10:53pm EST. I charged all night last night, wiped battery stats this morning as soon as I took it off the charger, and I have 52% right now! And I have used it more than I usually do. I don't know why that seems to have worked but I hope it does the same tomorrow.
Oh yeah, Setcpu set to 710 max, 245 min, screen set to manual brightness at 45%

Go on ebay and search for HTC Eris batteries. For $15-20 you can buy 2 extra batteries with an EXTERNAL charger. I run my batteries to 15% or less, pop it out, put in a fresh (cool) battery, and put the dead one on the charger. No more carrying a charger everywhere I go or using a landline because my cell is about to die. Then your settings don't really matter. Even if you can use 3 batteries in a day, you'll have a fresh one (or 2) charged by the time you burn up the 3rd one.

I just switched from the G2, and I don't seem to be getting as good of a battery life. I just went down from 50 percent to 4 percent in 3 hours. Is this normal?
I don't think my phone is sleeping when the screen off. I'm kind of new to android, so excuse me asking, but how do you check if you phone is not sleeping and draining battery while idle? Is there an application or something to check?
One more thing, I just got the new update yesterday. I heard that it's not good to use a task killer, but I'm now using the built in task manager to close apps before I lock my phone seems to be helping with battery life. What are you opinions on this?
Check the battery thread, life seems to vary along among the Vibrants. A lot are reporting 11-15 hours of use before needing a charge.
I read that it's good to put Wifi on never sleep (if you're on Wifi) and use a black wallpaper
Interesting, how do I go about changing the wifi to never sleep? I can't find it in the settings!
Drm running. Go2 apps running- Apps & stop it
Vibrant + xda app

If you change WiFi to never sleep, it eats battery like crazy (at least for me, I'm bought with no data, and could barely last a day from when I woke up to going to sleep). With WiFi art to never sleep when charging, I only drain around 40% in an awake day (from when wake up to going to sleep).
Also, when I set WiFi to never sleep, my cell standby usage skyrockets.

Extend battery life
Couple of things I have noticed with this phone
1. Get an app Task manager or similar type apps. There are a bunch of them in the store and here. This will allow you at one click to see what is on in programs and better manage that.
2. Go to the Development section here and read the Bionix 1.9 Thread. It explains how to recondition the battery. Even if your battery is new it is good information understanding how the phone views the battery.
3. If I am out of range or do not need, I stop the wifi and bluetooth. In the menu you can set the settings alot of ways, so you just have to experiment on this. (In home screen, hit lower left button and go to settings)
4. I use my email and phone ALL day (min 10hrs) and typically, I get 15-17 hr of use before it hits 10%
5. Finally, once you are comfortable with the phone, you can load a custom ROM from the Development section. The developers here are very through and Do squeeze the most out of the phone.
Good luck and you will love the phone as I do.

1 - terrible advice - esp with JI6 having one built in (long press home).
2 - This is also in the General sticky
5 - try bionix 1.9.0 (or 1 if you want alt lock screens) and try JACs oc/uv - great battery life so far.
On average use I get close to 24 hours out of a charge using mostly WiFi and enabling no-sleep option, running Bionix 1.9.1 with stock kernel with JI6 modem. I'm also running LauncherPro Plus with facebook widget set to auto-refresh every 5 minutes, the most frequent setting for Google sync, and NoLED notification. I think that is very reasonable.
p.s. I do not use task manager since the operating system is supposed to manage the apps on its own.

I use an app from the market called Y5 (free) to automatically shut down wifi if I'm in an area without it and back on if I'm in an area with it.
Works well for me.
My vibrant is less 23% after being off the charger for 4 hrs. One of those hours was me driving without using it.
Something is wrong. Dunno if it's the update, but something is lilling it FAST - wifi ang gps off the entire time...

I use the living hell out of my Vibrant, and usually it lasts for about 4-5 hours. This being during playing games with brightness maxed, or streaming music over 3G and/or Wi-fi.
If I have a day where I am not doing the above, and just using my phone for emial and the facebook and gmail synching, I easily get over 10 hours before I hit 20%.
All in all I am quite happy with it's battery life. I have just learned to leave my phone on the charger till full charge after streaming music drains it to <20%.
I really should put MP3's on it and test how much that drains the battery compared to streaming.
Either way, I get better performance on battery and memory management then my old (work supplied) BB Bold.
My G2 definitely has more battery life than my Vibrant. That said, once you apply the above mentioned tweaks and especially with JAC's OC/UV kernel, and setcpu set at 200-1000 at conservative, the Vibrant battery life improves quite a bit. Still, its not as good as my G2. But not that bad either..
Keep in mind that the G2 doesn't have to power a billboard sized SAMOLED screen either.
Other than that flash on of Sombionix's ROMs with either of the new kernels and then recondition.
I get pretty good battery life because I don't have 3G in my area so I keep it forced to edge and I don't use bluetooth ever and wifi stays off unless i need it.

Fully charged on the way to work. On the charger less than 4 hours later with moderate use. No better after update. Was using a task killer with minimal improvement. Love the Vibrant but despise it's battery life.
Something is wrong. I just went 26 hours down to 19% before charging

People, recondition the battery. It's easy.
Charge it to 100%, keep it plugged in and reboot to recovery, clear the battery stats, drain it all the way, then charge it back to 100% again.
You can start in the morning before work/school and finish at the end of the day. I've never had an issue with battery life on this phone. I can play 6 continuous hours of video/games on this thing and still have battery left.

Can't get past "Reinstall Packages"
I am trying to recalibrate my battery after the OTA destroyed it, but every time I select to reinstall packages so I can get to the battery section, it looks for Update.zip on my sdcard, and it wont let me get any further. All I can do is reboot the phone.... any suggestions?
hi guys, i'm a newbie when it comes to rooting and stuff
i reduced all my lcd settings (display is only at 10%, removed animations, etc), turned off unecessary apps (wifi, etc) and i'm using setCPU (so i could downgrade my cpu speed) after i learned how to root here with the ff settings:
cpu range 200-500 mHz, conservative.
my phone still seems to be draining fast. i'm not watching vids or playing games.
can anyone help me or give me tips which overclock actually worked for their S2?
i was hoping my battery would last about a day.
thanks!
Suggestions: restore your cpu settings to normal to establish a base line. Then download Osmonitor and see if any application is hogging your cpu. If not, then, in recovery wipe Dalvik cache (not anything else!).
You don't say what rom you are on but assuming you are not watching video files all day, you should get a full day easily.

Root has nothing to with battery life directly, but you can use T.B Pro to freeze some garbage apps always.
Besides you can't get any benefit from using SetCPU? LOL. Well I don't wanna a debate here, but that damn app will not do any useful thing other than mental satisfaction.
And you stop any app which is set as Automatic refresh in an specified interval, run as low as Widgets possible, Turn Off WiFi and Packet Data when not needed, and try to use Juice Defender which is doing a great job on mine.

thank you for the replies
@tangiers: can osmonitor also freeze useless apps? or it just merely monitors your phone?
@jimhaddon: what is an exchange account? i don't think i set-up anything like that while i was tinkering with my phone.

I beg to differ. After I isntalled SetCPU and Underclocked/Undervolted my CPU I found that my battery life increased quite a bit and was no longer experiencing battery heating.

I9100 CPU is smart enough to change it's state when needed, you don't need an additional 2US$ software for that, when will people agree this fact? Anyway, why shall I care!
I'm also in the camp that thinks setcpu is a myth for saving battery. The cpu already scales up and down as needed stock. At idle the cpu sits at 250 mhz.
SetCPU
I found out that setCpu actually drained my battery faster, so just uninstall it.
See if it gets better.
My battery drains too.
Solved that problem by charging overnight.
Sent from my GT-I9100 using xda premium
There are many factors that's can cause battery drain, wakelocks, signal strength, method of data wifi or 3g, display etc etc
You could have a rouge app that is keeping your phone awake, download betterbatterystats and check for partial wakelocks.
Signal strength can be a factor, see your current signal strength and then change the modem to see if this reduces.
No need to tinker with setcpu, you can underclock if you wish but generally leaving it on stock is fine.
Most importantly enjoy the phone don't get to obsessive with trying to save every ounce of battery its a smartphone at the end of the day otherwise we'd be carrying Nokia 3310s with us, and remember you can always charge nightly!

Things that drain the battery :
Gps

Wifi

Display brightness
Display time up setting
Try to configure them and see how much you can squeeze that .
Check on setup battery the top ranking of battery usage.

See my screen time above. I feel its pretty good. 6hrs+
I underclocked to 800mhz, auto brightness, ICS stock rom with the famous KH3 modem. The phone looses 2% over 8hrs of deep sleep. I think thats awesome. My phone lasts for at least 13hrs. (I charge it overnight and take it out @ 6am and use it till 11pm.)
Off topic: I was using my dad's iPhone 4 for a while and the battery life is amazing. But I still hate iphone.

since you are rooted, try flashing jeeboo kernel
other tips, if you are not using Google Now disable it, freeze samsung push service, settings -> wifi -> advanced -> network notifications - uncheck.
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.

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.

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 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.
I've been researching extensively how to improve my battery life on my Android phones and I believe I've found an amazing setup for the Atrix. My phone has been disconnected for 3:15 and I'm at 91% right now with moderate use. It used to burn about 5% an hour before with NO use. Yesterday, it lasted 14 hours and I still had 20% left when I went to bed.
Aura 1.1.3 Debloat #7 ROM
This ROM seems to be the lightest one I've tested. It's only 150 MB and very fast.
SetCPU
I set up a profile to underclock the processor all the way to 216 MHz when the screen is off. The processor is running at 1.1 GHz max. I haven't tested underclocking it to 1 GHz or 900 MHz. I'm sure that would improve the battery life even further and not have a huge impact on performance.
Battery mode (Android settings)
Obviously, it's on maximum battery saver.
General settings
I set the screen timeout to 30 seconds. Maybe 15 seconds is too short for you as it is for me, but that would save some more juice.
Every other battery-killing feature is on, like wifi, GPS and sync. I don't use task killers anymore and found out that my battery life actually improved a lot after I ditched Advanced Task Killer.
I just wanted to share this with the community. I hope it helps you. Any suggestions to improve it even further are very welcome.
Yeah task killers are pretty much useless, watchdog is a wonderful alternative.

Interesting and thanks for sharing, but...
I can get almost the same results by using any other ROM without SetCPU and just using Max Battery Savings but I'm not interested on that setup because I need to have PUSH email all day.
Maximum Battery Savings makes push emails useless, and for a device that's supposed to be "connected" push mail is a must (at least for me).
Unfortunately, push mail is what kills batteries, specially on 3G/4G.

My phone was maximum battery savings one time for some reason. I didn't do it. But for some reason, it was seriously draininng my battery bad. I think i was on 2.2/froyo before i unlocked so i don't know if that had anything to do with it. I do know, i haven't had reason to try it intentionally since my battery is great overall. It does help since atnt turned up the juice on the 3g and called it 4g reception has been very satisfactory lately helping power consumption by not having to look for a signal as often.
I voided my warranty.

Exactly! When the phone switches back and forth 2G and 3G/4G it drains a lot of power. So it too depends on the zone we are in at the moment and that's one of the reason we see a lot of different results among users. Of course, phone and app/game/internet usage style also counts.
Cheers!

I think a lot of people don't realize that terrible reception can account for terrible battery. Often we don't get that feedback when people are whining about battery. Also, lots of the people whining about battery play lots of games, and some of those games that put the gpu through it paces suck up juice faster, but the user is not realistic about that either and expects battery life of a phone that is used lightly.

Yay for undervolting
not "killing" aka "ending" or possibly more familiar "closing" your running apps.. that's like, like if you log into your windows box and you don't have the "X" buttons on the window caption bar.. you just leave everything that you run running until you shutdown..
before you even try to retort, obviously there are exceptions. in windows explorer.exe runs endlessly until you shutdown. on your android device that's the equivalent of your preferred launcher.
what else.. msn? the equivalent of your favorite sms app. facebook and notifications? similar to that browser you keep open with 5 or 6 tabs swiftly consuming your precious processor.
i'm not sure an argument even exists. "task killers" has "killers" in the name which naturally has negative connotations. call it a task manager. windows has a task manager.
other than that nice tips
I am stock everything.. even launcher
3hrs 14min screen on time
~12ish hours off the charger
still says 50% battery. which means 50%-59% on motoblur
pretty darn good eh?
Don't understand the point you were trying to make. Are you saying killers/manager is worthwhile or were you trying make a worthless point about the names?
Anyways task managers are worthless. A good comparison to make are mid/high end laptops and their ram. On a forum I frequent, users were comparing their battery runtime with similar setups. Some were getting extra ~hour or so than others who couldn't figure out why they were getting shafted on battery. Some people don't realize that 4 dimms of ram consume twice the power of 2 dimms of ram no matter the gb of x amount of ram. Thus its better to have 2 dimms of 4gb each than it is 4 dimms of 2gb. The ram consumes power whether you use it or not if it is connected. The 1gb of ram in the atrix consumes the same amount of juice whether its holding 300 mb of data or 800 mb of data. Whether the cpu is computing with something active or not in the ram is what's relevant. Task managers only help when you have a rogue app. Id rather uninstall it then deal with a poorly written app.

Although that may be true for windows computers it its not with Linux which Android is based on. I know that there are virtual machines and all that jazz for the apps but the core system is all Linux and it's even optimized for battery life so when you press the home button yeah that is still running in the background but if you ever need to use that ram it either clears that app from the ram or (based on the app) kills its altogether. And like someone else said ram uses the same amount of power weather it's being used or not.
Also if you're using well written apps then they shouldn't be using any CPU in the background.
If there is some app that's hogging CPU in the background then you need to just uninstall it. Task killers especially auto task killers are actually using a lot of your CPU constantly checking for apps that are using too much ram but Android already does that automatically.
tl;dr
Linux can manage its own ram without you and for the love of God, stop using task killers they're making everything worse.
i was defending their usefulness in general not so much their effectiveness in battery preservation. probably the wrong thread. if any its minimal.
i'm talking about active task management tho. when i'm done browsing the web and want to fire up pewpew for some old school polygonal destruction i kill the browser entirely. i guess its really based on the type of user you are whether or not benefit is to be had. some people are active while others are standby

Sure, it depends on how you use the phone and the strength of the signal you're getting in your area. Would you guys just turn data off in bad signal areas to save battery? How would you handle that?
This is what happened. My battery is doing amazing. I changed the battery mode to Performance during the day and I still have 65% after 12 hours. Not bad. It's about 2.9% an hour. The display was used for a total of 2 hours and 10 minutes.
Battery life posts are useless unless we have some kind of standards during testing.
Like setup your system and then a 15min phone call, 1 hour of video/ ect.. same call.. same video same ect .. ran on each battery setup will give a truer idea on what saves battery the best.
This whole .. it was off charger for 5.33 hours and I used it alot and its at xx% doesn't hardly mean anything.. how much use is alot? How much is little?
Need some kind of same standard test that can be run..
nice to know
Why do custom roms get worse life on the ATRIX? Im new to this phone. (Used to be a HTC only guy)

Mostly its not about the ROMs you use, but the Kernel or Baseband (Radio) firmware.
At least for me it's been much better than with the original ROM.
Also you must take into consideration other factors like type of use, voice/data signal quality on your area, and many other factors.
