I've always read in the past that the app doesnt actually help with battery life because its purpose was for OCing and Android regulates the cpu clocks already.
So I'm wondering, for those currently using it, have you noticed any difference in battery life (without underclocking while in use)? and if so what profiles are you using?

I have just one profile, screen off= 216/216. I'm now on 14 hours with 30% left. Much better than before, when I was getting 11 hours at the most.
I also use the battery calibration app. But that's all I've done.
Just want to add I use wifi calling, and I run everything else, gps and syncing gmail and facebook is on. Screen is set to auto brightness. The only thing I have off is bluetooth.

Android does regulate the cpu, but I don't think it will take advantage of more conservative governor modes unless you tell it to. That's only relevant if the kernel supports more conservative governor modes. And, as the other responses have pointed out, you can force Android to be more conservative by capping the max clock speed.
Hmm... Guess its worth a shot. Good lookin out guys.
when i go into setcpu there are alot of options to choose there is no auto detect like on my mytouch 4g. how did you guys get it to work. i picked the last option which was custom and it forced close on me.

Yeah.. When I hit the tegra 2 option it wont let me change the governor.
You need to be rooted so that you can let set CPU have super user access. Are you rooted yet?

I think that that means that the kernel is not supported for the "automatic" governors. However, you can still create profiles to regulate the CPU based on perameters that you set, i.e. Screen off 216/216

So all G2x see the same in setcpu - no autodetect and only governor available is "driver"?
Will custom ROMs like CM7 change this?
SetCPU improved my battery life tremendously! Before I was losing about 15-30% and hour, since 8:30 this morning my battery only dropped to 73%. I set my active profile between 457mhz and 816mhz depending on remaining battery and it's still fast as hell.

From what I've heard, yes, that is what every g2x setcpu user sees. I don't know whether CM7 will fix this, or maybe later versions of setcpu

Once we get some custom kernels, we should be able to change the governors in setCPU, dependent upon on what the kernel supports.
SetCPU Custom Frequencies for G2X
I got SetCPU today and was playing around with it and it looked like it was limiting my CPU all the time due to lack of profile, not just when I had the screen off per my profile so I looked into making a text file for custom frequencies and am posting it here since there doesn't seem to be any help for g2x with it.
This is a really simple file, tell me if you guys have any better ideas, I just put in:
216000,528000,712400,1000000
I'm attaching it. I put the file in my dropbox, grabbed it via the app and then moved it to /sdcard/setcpu.txt via astro file manager then loaded custom profile from within setcpu. Hopefully this saves someone some time or you can tell me if I'm going about this the wrong way
I'm sure it could be fine tuned more but I was getting irritated at how much of a pain it was to unlock the phone with it set too low, so for screen off I have it set to 216->528. You could add 254000 in or something. The phone seems to be as usable as before now with setcpu enabled like this while it should be limiting the cpu when the screen is off. It sucked (well not the battery) without a custom profile.

Yep, I agree. My phone has been off the charger for almost 9 hours, and I'm at 70%.
I have everything on, including wifi calling, and one profile in Setcpu for screen off 216/216.

Actually, your assumption is wrong, as is often the case.
I'd quantify it more as normal use. Lots of texts, some games of Pro pool, a few phone calls, checking Pulse 3-4 times during the day for 10 minutes at a time, some mild web browsing and watching a few youtube videos.
I ended up at around 18-19 hours of of use.
Today, I'm off the charger for 8 hours, and I still have 45% left, and I would say that's with some moderate to heavy use.

Try upping it to 216/312 or a tad higher and you should be fine.
1.Reduce display brightness of your screen
Although Samsung Galaxy S come with Super AMOLED which is supposedly to reduce your battery consumption but ironically it is one of the biggest battery life eater of your phone. Try to disable Automatic brightness and set it to the lowest level will improve your battery life a lot.
2. Remove unused widget in the menu
You must always remember that the more widget you have, the more battery life will be consumed up especially those widgets that use data connection and auto sync based on schedule. PS: only keep those widgets that you really need.
3.4. Turn off Bluetooth, GPS when idle
Only turn on Bluetooth and GPS when you need it, otherwise please disable it as it will consume your battery resources. Or please ensure that the charger is hook on your device when you turn on the GPS in the car.
5. Turn off 3G data connection, use Wi-Fi instead
Always gets connected with Wi-Fi when available. 3G data connection consume more battery compare to Wi-Fi connection. Turn off both of them when not needed.
6. Ensure you phone have a good signal as poor signal consume more battery life
When the phone is at the poor receiving end it will tend to use more power than usual to increase its signal strength with the communication tower. So it is always good to make sure that your phone has a good signal reception. You can try to switch to 2G if 3G connection signal in your area is poor.
7. Try to disable / reduce auto-sync whenever possible
All you have learned, data connection does consume lot of your battery life. By disabling the background scheduled auto-sync applications like Facebook, Gmail and Twitter can save your phone lot deal of battery life. If you really have to turn on the auto-sync feature in the phone try to reduce the frequency of auto-sync will also help to improve your phone battery life.
8. Disable new Samsung Apps notification
You can turn off new Samsung Apps notification if you not using it.
The configuration can be access through ~ >Settings >Application > Samsung Apps > Off
9. Turn off motion sensor
Only enable the Samsung Galaxy S Motion features that you using and try to disable those you not using like turn over, tilt, panning and double tap, turn them off as it might save your some battery life.
10. Use solid black static wallpaper and no live wallpaper
Most of the phone including Samsung Galaxy S Super AMOLED will tend to use less power on just solid black wallpaper than a lively solid white color based wallpaper because there will be almost no backlight on the screen. Please do bear in mind that a lovely animation live wallpaper will even cost you more battery life as ~ CPU power = battery life.
11. Fully close application that not use
Samsung Galaxy S is a super multitasking mini computer that come with dual-core processor but running a lot of applications at the background can actually increase your battery usage because they all require your phone CPU processing power. So it is advisable to fully close all the background applications that you not needed.
12. Freeze unused bundle applications
Too many original bundle software running in your Samsung Galaxy S? Freeze them… Titanium Backup Pro provide a way for you to freeze away all the stock application like Social Hub, Email, Maps that are running and utilizing your phone processing power even when you’r not using them. Ps: Your phone need to be rooted before you can use the Titanium Backup Pro.
13. Undervolt and underclock You 800Mhz GHz CPU
Aside from display, Samsung Galaxy S′s powerful CPU is one of the reason why your battery life eat up so fast. You can just underclock and undervolt it with SetCPU if you don’t need that much of processing power. Ps: Your phone need to be rooted before you can use the SetCPU.
14.Download and install JuiceDefender
With an amazingly over 5,000,000 downloads recorded so far in the Android market, JuiceDefender will definately extend your the battery life of your Samsung Galaxy S. JuiceDefender pack with powerful and easy to use power manager app that specifically designed to extend the battery life of your Android device. It can automatically and transparently manages the utilisation of your S battery like when to enable and disable the 3G/4G connectivity and WiFi.
JuiceDefender is available in the Android Market for free and if you would like to have a more powerful (customisable) version you can download the add-on JuiceDefender Ultimate for a small fee of $6.83.
15. Use custom ROM / firmware
Custom ROM / firmware offer a lot of optimization and tweaks to improve the performance of your battery life. You can try it out if you feel that after you have tried out all the tips above and your battery still draining too fast. But please be reminded that flashing a custom ROM / firmware will be voiding the warranty provided by Samsung.
Please let me know if there are other tips and tweaks to improve battery life of Samsung Galaxy S/Cappy that I have missed out.
I think #14 is not necessary if you are running a custom ROM
why wouldnt it be?
I believe number 11 has been proven untrue in the fact that killing tasks that the phone will reopen soon after actually reduces battery life hence the reason task killers are bad. Also the captivate only has a single core processor.
Other than that nice work it should help people out.
If you use a stock ROM with no voodoo color built into the kernel, then use full brightness, I do and I get great battery life, the screen isn't the biggest battery life sucker.... this isn't the greatest battery saving thread from what I can see.
Sent from my SGH-I897 using xda premium
Generally good tips, but definitely a few holes here and there.
For example, GPS doesn't drain when 'on', only when certain apps use it, making it pretty safe to keep toggled on all the time.
You can go further with SetCPU and other similar apps but underclocking during screen off, and I think that's helping me save battery in my personal experience.
Having a black wallpaper is good and all, but I feel that doing that is a bit too far in optimizing battery life. What's the point of having a pretty decent screen when all you do is use a black wallpaper?
Or flash Darky rom 10.2 Extreme Edition.

That is no good, considering the screen should be taking most of the power.
You either arent using your phone or you are crushing batteries in hours.
No I'm using it, Android OS process in ICS includes more than what they do in GB. It last all day (~15 hours with %40 left)
Sent from my SGH-I897 using xda premium
Yeah I have the ICS port, build three, and the battery sucked the first day due to all the downloading and cpu usage, but after that and a full charge and battery diagnostic wipe it was a great life with decent usage on apps and data and messaging with auto brightness
In Point 11, Captivate uses single processor....and killing system apps causes more battery drains....
My limited experience with roms suggests that as roms are works-in-progress their battery life can vary widely. Serenity6.1 has really seemed to be a long life rom.
These steps do make a big difference, also the Beta 2 build for ICS solves a lot of issues that users had with ICS battery life. Honestly if you want even more battery life grab the 3500 mah extended battery off amazon for $10.

Basically dont use your smartphone as a smartphone. Thats what you're saying by turning off all the good features of the phone.
1, 3, 4, 11 are like NO DUH!!!
5. Are you saying use EDGE? It will save some battery, but you have to consider it may take longer to load something, and thus the screen might be on longer, negating savings. Plus, it's a PITA to change back and forth.
6. Other than switching to EDGE, not really in your control.
7. That's stupid. It defeats the whole purpose of having a smartphone.
9. As long as you lock orientation. I doubt it saves much though...
15. YES, that can be HUGE.

Idk if this goes in Q/A or not I never had a Q/A section as I came from the amaze but anyway. What battery savers do you guys find best? I Use Batter Defender but doesn't seem to really extend it. Would i be better of not using one at all?
I use 3 programs to help me maximize my battery life.
1) Badass Battery Monitor to figure out what's sucking juice, how long I've left, and how long until I'm full.
2) 2x Battery to manage background data. This probably saves me the most battery by disabling that data transfer a lot of the time.
3) Lux Auto Brightness to tweak my screen brightness. It's pretty much on "dark" now all the time aside for when I'm in really bright light.
JuiceDefender
I use the free version and it's very good!
I think the most effective battery saver is to flash a kernel that has become voltage control features and undervolt the cpu.

I'm not a fan of under volting the CPU. Mainly because if my understanding of Ohms Law is correct, it's pointless. And my personal experience with it seems to corroborate my feelings.
Under volting the CPU in my experience just introduces stability and reliability issues. I've personally never seen any battery savings from it, especially since the CPU should, theoretically, just draw more current (I) to compensate for the lower voltage (E). It's watts (P = ExI) that matter, and the CPU, if I understand correctly, is going to demand the necessary P for the frequency requested. So under volting either starves the CPU (it can't get enough P), or over currents it (it draws more I to compensate for less E). There are slight variations in each CPU, obviously, which may allow for a margin of under volting to be possible without issue, but the battery savings of this, I feel, are so small, any you notice are most likely a placebo effect. Your screen, and apps constantly polling the CPU or network are your biggest source of battery drain to worry about IMHO.

With an higher frequency the phone will use more power, like a pc processor when you overclock it so this is natural, but overclocking/downclocking has nothing to do with undervolting, MadJoe is right.
With JuiceDefender for example you can set your 3g/4g to shut off when you don't use the phone, it activates 3g/4g when you use your phone and at regular intervals in backgroud so it can fetch emails etc.
All automatic so you don't have to switch off and back on network connection every time.
As network connection is one of the services that consumes the battery a lot this is really effective and really improves battery life!
I've read a lot of complaints about these PowerManagement Apps using more battery life then they safe.
I don't know if this is right.
At the moment I'm running CM9 with modified auto-brightness options, auto-sync and 2G/3G/WIFI always on.
I'm really happy with the battery life I get, so I don't see why you would need a Battery Saver app with this phone.

Hard to answer without testing some roms for yourself....
Synergy Rom is a good start which eliminates bloat from the provider...and then optimize the rom. Add a better kernel over stock like Imo or Ziggy and that took controlling CPU power (depending on your setting) can help gain better battery life...mean over 8+ or 12+ hours of life
30+ hours with almost 4 hours of screen time : cm10

This isn't really a tweak or script, but turning off mobile data and using wifi helps a ton. Constantly searching for 3G or 4G connection is what kills my phone's battery.
Here is what helps me..
-turn off any data that doesn't need to be running in the background while you are using it i.e...gps, 4g, bluetooth. (Use "phone info" from the market to switch from 3g to 4g.
http://forum.xda-developers.com/showthread.php?t=1771840
-make email manual push. when you have email set to constantly search for new incoming messages it can run down more than needed. if nothing else switch to every 15-30 min.
- turn off all notifications that you dont need to be notified about
-screen brightness will be a HUGE battery eater. I have mine set at 1% most of the day which really helps. this screen is bright enough to have it that low and still see well.
-download "widgetsoid x2" free. a fully customizable toggle bar which will allow for easy on off for items like bluetooth, gps, wifi and gives you a brightness option to customize 3 settings. I have mine set for 1, 25 and 45%
-use setcpu or another app alike to control cpu. create a profile for "screen off".I set my profile at 348x486. this drops the processor while screen is in sleep mode and will save battery life.
-I dont know how effective this is, but I heard it helps and makes sense. Choose a dark wallpaper. Having a bright, full white wallpaper takes more battery life to display.
As for ROM's, its hard to say. there are so many things to take into consideration when someone says they got 30 hours on a rom vs the next person who only gets 12 hours. how much are they using it, what do they have running inthe background...etc. I tried both bean and synergy and I prefer bean. He just released R6 yesterday and people seem to like it a lot. I personally prefer R2, his original release. It has been super solid and I have had better results from it over 3.1, V5 and his late R6. My buddy has had GREAT results with synergy, but I did not. I gave it a week and ended up restoring back to bean.
download BatterySaver app from market. My s3 runs 12-15 hours on "Intelligent Mode"
Honestly, you can only do so much with software tweaks. If you're a hardcore power user, I suggest getting an extra battery of a similar size (~2000mah) or getting an extended battery.
As for what you can do to save battery, the only thing I can think of that people haven't already mentioned is turning off animations. It can make things feel a bit choppy, but you'll get things done faster, which means less screen time.
I just got upgraded from CM 9 stable to CM 10 stable and I love it. Only problem is battery life. I feel about a 10-15% reduction with the new upgrade. I've had CM 10 for about 4 days now. I don't want to touch the performance settings without knowing what I'm doing. Is there a way to change my performance settings to extend the battery life? Also has anybody played with a different kernel with CM 10 stable? Thanks

Don't worry about changing the cpu and governor settings. There is an option to set at boot. Make sure that is disabled, so if you have any problems a reboot will go back to default settings. I use the conservative governor, and have my minimum cpu speed set to 192. I've read that that speed is not entirely stable for many people, but seems to be working fine for me. That has been pretty good for battery life for me. I believe the default governor is interactive now, and the minimum cpu speed is set to 384 by default.
Do you just "feel" a battery difference, or do you have any actual numbers to back up that assertion? Keep a close eye on Settings / Battery and use Better Battery Stats to record solid numbers and identify what's actually eating your battery.
Also turn off google now location settings if ur not using it. They are really hard on the battery.

Thanks for the replies.
It seems to be my screen that is responsible for eating up my battery. Have had the phone disconnected from the charger for 4 hours now and all I've done is 20 min with screen time doing a little bit of texting and facebook and my charge is at 75. I have the automatic brightness setting off and put my setting at pretty low.
The cell stand-by battery usage is 8% during these 4 hours. Should I maybe try another radio or is this normal? It lost signal for about 10 min today.
Just turned off google now and selected the conservative governor. Let's see if this makes a difference.
I used to be able to go all day with my phone with CM 9 and I even have the nexus battery.
Thank you for all your help
That's most definitely not normal, at least in my experience. Are you using the vanilla CM10 or some variant?
Some things to try:
Install Better Battery Stats (find the free version on XDA via a search) to see if any apps are causing wakelocks. This is a must.
Use CPU Spy or something similar to see if your phone is entering Deep Sleep. This is a must.
Turn off Google Now unless you actually use it
Turn off all unnecessary radios (WiFi, Bluetooth, GPS) unless you're actually using them
Turn off all auto-refresh settings in every app you have -- all social apps and weather are the biggies
For me, turning off the default auto-refresh in Facebook, Google+ and Twitter are massive savings alone, then Settings / Battery & BBS will help you locate the remainder of the headaches quite easily.
You might want to consider swapping kernels too, or at the very least reconsider your CPU governor and scheduler settings.
I would stay away from conservative governor you won't get much performance out of that, stick with what comes stock and use on demand.... even the default interactive sucks my battery down

I'm currently running the vanilla CM10
Turned off google now location access and set the govern to on demand early this morning and it is performing a little better most def.
I have noticed that my phone lost signal 4 times during the day for periods varying 5-10 min. I am currently on the I727UCLF6 radio. I'm thinking maybe I should try another one. Could that help with that battery maybe?
I have been thinking about switching kernels but I am a little doubtful because I don't want to mess up my phone too much since I so heavily depend on it. I loved the hotcakez kernel that came with AOCP, maybe i'll give it a shot this weekend.
Thanks for all the help people! Def the best forum by far on the web.

Just do a nandroid backup of the entire phone first before installing a new kernel and your risk drops to zero. If you install it and it all goes to hell, just boot back into recovery and restore your backup.
As for radio ... if you drop signal that often and your phone is constantly searching for one, I suppose that could impact the battery, sure. Are you certain you're in an area with solid coverage, though?

Yea I might have to play around with some kernels this weekend. Luckily it is a long weekend so I'll have some time if I mess up
My phone will go from 4 bars and a good signal at -78 dBM in my apartment and then randomly I'll lose signal for abut 5-10 minutes. A restart usually does the trick or I can just wait until it regains the signal which can be frustrating. I never had any problems with my signal at home running CM 10 so that leads me to think that there might be some problems with the radio.
Just want to confirm that these are the 5 radios I can use for AT&T even though I'm running JB.

I've been using a UCLI3 modem I found on XDA a couple of weeks ago, it has been incredibly stable and strong for me. But as many people far wiser than me have said elsewhere, everyone's mileage with radios varies and it really just takes some testing to see what works best for you.
so I should be able to run the 5 ICS radios I found eventho im running jb right?
thanks for your help
