What are the settings you guys have to save battery life? Also How do I setup the profiles?
Help From No One???
I turn background data off, turn data and wifi off. My setcpu profiles. Screen off max300 min300,100 priority. I got a droid x and my battery lasts with medium to light use 24 hours before I have to charge.

Check your governor settings too.
I've found conservative with 80/55 up/down threshold, 10% steps to give a good medium between performance and battery life. Also, I've downclocked the max cpu speed to 921Mhz. 128Mhz for sleeping.
Edit: I do have background data turned on, as well as enable always on data toggled on under settings/networks/mobile data. Wifi is to never sleep. I do try to use wifi over 3g whenever possible - it extends battery life considerably.
With light use, I get 3-4 days, moderate use ~2 days, and heavy use will give a good solid day.
Can't thank from Tapatalk, but excellent reply. I like the detail.

N/P.. I experimented with a number of different settings a while back, and although i'm sure this could probably be tweaked even further, it works exceptionally well as is. One of the methods of measuring was to see the stats from 'time_in_state'. I was looking for good utilization of cpu freq's between the min/max. My other criteria was good response in interactive apps (email, browser, scrolling).
ymmv.
PS. I do not use setcpu, but the above along with the sleeping script in the rom (see below), achieves the same thing.

I'm really struggling with battery life at the moment. Has anyone got settings I can use to save on battery life in SetCpu? Profiles etc
+1
I'd like to know too.
I would also like to know =[ my battery dies wayy too fast. I have the darkstone froyo build on my htc hd2 phone energy rom. Any programs or SETcpu settings that will help out?
If your on a rom with preflock disabled then you can underclock.
The only thing you need to change in setcpu really is to make a profile for screen off and set it to 245 (or whatever is the lowest I can't remember) both max and min (leave it on demand, or interactive if your rom has that).
This should give you about 10-15 hours longer battery life
so i wouldnt have to make any other profiles like battery? temperature? stuff like that? should i get rid of my green power and advanced task killer?
No you can keep them (well I don't know what green power is....)
The other profiles are mainly only needed if your OVERCLOCKING, however if your not touching the default max (main profile) then your not overclocking (1ghz).
To save power you UNDERCLOCK which setting a lowered screen off profile would do.
If your slowing the CPU down then the temperature will not rise, so that profile is not needed.
And you don't need to slow the phone down when your using it so none of the others are really needed either.

i think im kinda get what you're saying (sorry im kind of slow) so i had just deleted my other profiles and made a screen off one have it set to max all the way right and min all the way left, on demand, priority 100. Now on the main screen i think i touched it cause i read somewhere for max all the way to the right and min all the way to the left. This is confusing lol
The settings I have for my Desire:
Default:
Conservative 245-998
Profiles:
Screen Off - Priority 100 - Powersave
Charging/Full - Priority 50 - OnDemand 245-1305
Battery < 30 - Priority 0 - PowerSave
Running along side JuiceDefender, battery life is acceptable to me

I used darkstones froyo for awhile too. Battery drain killed it for me. I had no luck with anything. Changed to a nand build and its much better. Apparently SD builds just use more battery. With the SD froyo I could never stay below 60ma a few times would drop to less than 10ma but just not consistent. I lost about 8% an hour in sleep mode. Give a well designed nand build a go. In sleep I hover AT 4ma. My battery with Moderate use easily last the day, heavy use (multiple calls, emails, and browsing for an hour or two) still does require a recharge
Im using carbon ara theme with pcb just turn data off wen aint using it via toggle and have a profile for sleep in set cpu for min and max of 245 and from full charfe at 7am by 6 pm im still 65%. Thats using fb checkin email playing angrybirds and checking the forum

I was wondering is someone can help me. I've been using Deck's ROM's for the HTC EVO 4G for some time now and I hear about all these guys getting 20-30 hrs of battery life. I'm currently on 1.2.1 and have never got probably more then 11 hours out of my battery life with heavy or mederate usage. I've updated all my radios, wimax, etc....I've tried different kernels, I've installed vipermod and undervolted, I have CPU profiles. I've installed a new 3F3D driver. I've tried the wake lock fixes and still nothing has changed. Am I missing something here to how these other guys can get that performance out of their batterys. I'd like to post this directly to his thread but this is my first post and I guess I need at least 10 posts. I'm a bit of a noob but can hold my own.
I run decks with tiamat kernel 4.0.5 and I get outstanding battery life. Give this a try then let me know how it works out. Check your accounts to see if anything is synching that's insignificant. Then check your apps update frequencies. Lastly, turn off all of the haptic feedbacks, animations, and effects. Live wallpapers kill a lot of battery too. You might also want to try enabling and disabling auto brightness to see which is more energy efficient. If your overall goal is great battery life, then a lot of the bells & whistles are pointless.

I've tried tiamat 3.3.7, 4.0.5, and 4.0.6 and have got the same results with all three. I've tested each and one of these over about a week period. Currently I am trying SavagedZen 2.2.1 and up til this morning it hasn't changed much. I've took off all auto syncs. All haptic feedbacks, animations, and effects have been turned off. Never use live wallpapers and have read that lighter wallpapers will conserve battery. Right now I have auto brightness off and down to about 35-40%. I did however just checked off data enabled about 2 hrs ago and seem to have got better battery since. So far I'm at 82% with about 4 hours of moderate use. (mostly texting and surfing the web). I didn't know if there was any other tweaks internally that I'm missing or if it's more of a puzzle with what combinations to use.
Just saw my background data was enabled. I unchecked that as well. We will see how this goes I guess.
It seems like it's definitely data related. I downloaded skype from one of the forums strait to the phone and my battery percentage went from 79% to 68% just for the duration of the download. Is this common?
Do you use an SBC kernel? Have you whipped battery stats in recovery? Have you tried using the kernel governors (smartass, powersave, conservative) without setcpu?

I have used kernels with SBC and without and haven't seen much difference besides the initial 10% loss of battery. I usually I wipe cache, Dalvik cache, and battery stats everytime I flash a new ROM in recovery. I usually do a factory restore too. I've used smartass and savaged zen as governers as well. Currently I'm using savagedzen governer with a max at 1036 and a min at 245. I also calibrate the battery when i flash a new ROM. Currently I'm standing at 60% battery with about 7hrs and 37 min on battery. Probably the best battery life I've seen. I'm still seeing massive drains when I use 3G. I was just on xda forums on my phone for about 5 min. and the battery went from 65% to 60%. If I turn 3G off it stands idle for awhile.
I'm scratching my head trying to think of what will help. You probably won't like this, but when my rom has me stumped with a problem, I wipe and start over. Maybe an extended battery is the answer? They are dirt cheap for the EVO now.

Yea I was thinking about an extended battery as well. It seems like taking 3G off does wonders for the battery. Are you keeping yours on or off to get great battery life?

Lowering your max and min cpu frequencies will improve your battery life. I've always used 128 MHz as a min with no ill effects. Ever since I got my evo I've kept the max at 998 MHz and it was plenty fast, but I am currently trying out 691 MHz max and it seems just as snappy so far (battery life was great at 998 MHz max for low or moderate usage, but with heavy usage I've noticed it drains too fast). I'll probably try out some lower max frequencies to see how low I can go without affecting performance.

Use JuiceDefender to automatically toggle your data connection (3g/1x) off when the screen is off. This will dramatically improve your battery life especially when you're in areas with poor signal. If you want, you can set it to turn on the data connection at user-defined intervals so emails, google voice, and anything else that needs a data connection to be refreshed periodically can go through. With the paid version, you can even allow exceptions for programs like google music, pandora, or wireless tether, so they can keep the connection while the screen is off if they're in use.
Ill try juicedefender. I had it before but didn't really know what settings to use. Current battery is doing well. I'm curious to if all these people experiencing 20-30 hrs of battery life have data turned off a alot. I'm currently at about 14 hrs. with about 42 percent left. Thanks for all ur advice.

I can easily get over 40 hours with light usage and over 20 hours with moderate usage, but that's only because of JuiceDefender. Without it, my battery drains like crazy at work where there's really bad reception.
I use the customize profile with mobile data enabled, schedule enabled at a frequency of 30 min, and apps enabled when the screen is off for google music, pandora, and wireless tether. I also enable the text notification which puts the icon in the status bar. I've run into problems when I disabled notification where JD gets shut down in low memory situations, but having the icon in the status bar prevents that. I leave wifi, location, and night mode diabled, but that's just because they're not useful for my usage. I'm sure the other profiles work fine as well, but I just like knowing and controlling exactly what JD is going to do.
Try using saveged Zen with conservative governer, viper mod and other little things people have mentioned

I'm going to run JD all day today with those settings to see what it does for battery life with my data on. Yesterday seemed to be the best battery life I've recieved with data off for the majority of the day. Got about 17 hrs with 39% left. I'm happy with that. If JD can get me something like that without having to toggle with data on/off that will be nice.

I've run viper mod with tiamat before and undervolted 50mv with little or no change in the overall performance of the battery. Any suggested settings for savaged zen using viper mod?
Undervolt as much as you can, all phones are different. As for jd, sorry I forgot about that. It's a HUGE improvement. Your battery can pretty much double. It can be a little annoying in some cases.

Didn't really get to do a full trial on battery life yesterday. I downloaded a Sense Rom and tried some troubleshooting that I read on Deck's page but it didn't work. Today will be the first full day I try JD with 3G on. I will probably try viiper mod tomorrow after the results I get for today. Thank for the help guys.

You can't judge in one day.. you have to wait like 3 days of use to let it settle down
Deck's + SZ + SuperCharger script + ViperMod script.
I believe I have found what i belive is just about the perfect setup for this ROM
My evo is lightning fast, in app performance is almost comparable to my xoom
And with heavy usage my battery lasts at least twenty hours
Kernel: savaged Zen 2.2.1 bfs
Setcpu info: Max clock to 1136, try 1152 if 1136 is stable for Max clock, min 245. Savaged Zen governor, screen off profile with interactivex governor and min bumped to 384mhz. Eliminates all screen on lag
Market app: chainfire 3d its a graphics driver that increases all animations, 3d effects efficiency and speed, and improves battery life IMO follow in app instructions and install the driver, make sure to nand backup first and to not have the phone connected to the charger or computer when installing
Market app: battery calibration wipes battery stats to build new ones that are correct for your ROM kernel setup
Advanced setting in settings menu: performance settings, VM heap size set to 48
Market app : SD booster set SD cache to 3000 makes all SD apps and media faster.
Market app : busy box install 1.18.4
After all this install any user apps you wish and run fix permissions in ROM manager or recovery
Its a lengthy setup, but there is much profit to be had. This setup is faster then I've ever seen an evo run and has the best battery life of any ROM kernel combo I've tested.

A few days ago I started running a nightly of Franco Kernel. My battery life immediately increased and I was able to run for about 18 hours and 2.5 hours of screen time. However, after each progressive day, the battery life has decreased steadily until today I was barely able to squeeze out 12. I've checked my battery stats and it doesn't show that any particular app is hogging all the battery or anything. CPUSpy also says that it's entering deep sleep as usual. Any ideas and has anyone encountered this issue? Franco 156 with Liquidcool 1.4
Thanks in advance.

That could be dependant on soooo many variables... How is your signal strength in the area you reside? What are your settings, governors, Any kernel wakelocks? What are your ROM settings. Are you in WIFI, 2G or more?
I don't think you'll get an easy answer on your question here. Just play with your settings and see what suits you best.
I myself am using Franco with the Rascream ROM and getting currently 4hrs of screen on time on stock 1750 battery.
My settings:
ROM: Rascream
Kernel: Franco r174
Powermode: Balanced
Governor: On demand
Min: 729 MHz
Max 1228 MHz
OMAP4 interface 1.4
No other performance or battery saving apps or tweaks....
Just test your settings and be aware of wakelocks (but you allready are since you have the batterystat log included).

That is simple. I get about 17hrs uncharge off which 3,5 to 4 screen on. That is sufficient for my use. With Lazy and power safe I feel that the performance suffers too much. With these settings everything is still smooth and snappy... as you can see I adjusted the min and max from my CPU above the standard that comes with balanced power mode for the same purpose.
Thanks guys. I moved some things around and I'm getting better life again. It seems like the problem lied in either an app called 1Weather or My Data Manager. Have any of you heard anything about those apps?

I've used 1weather for months and it has never negatively effected my battery.
I'll play around with it for a few days. I wouldn't have imagined that it would be 1weather, but due to the nature of My Data Manger constantly keeping track of something could have run the battery down. Funny how it never showed up anywhere. Though the battery drained significantly during standby. I uninstalled both and battery is fine now. I'll see what happens when i put them back.
What's a good figure for battery life on the GS3? The best I've got is about 31 hours using on demand and bfq. Any one got better life using other settings? I heard someone getting about 43 hours life but that seemed to be a little unbelievable. Let me know what your getting
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
What you reported is definitely "the average". Most actually only get a day, if they're lucky of moderate use and have to plug in before sleep every evening and get going on charge in morning. So its more like 15 hours actually. And your 31 max is very common high end for people who've stretched it out.
I'm not sure if you're stock rom or not and if rooted either but that makes a big difference.
I'm rooted ( and would ALWAYS RECOMMEND ROOT FOR EVERYONE EVEN UF NOT FLASHING ANY ROMS AND STAYING ON STOCK. The ability to have full control is important.
Changing kernels and more importantly, undervolting, will give you that longer life you're looking for.
I'm currently on KyanROM with either Ktoonez or Faux kernel (heavily tweaking and testing both) and have this phone beautifully undervolted to exceptionally low and very stable mv numbers! Thus getting me that lovely 36-45hour average (you mentioned you saw posted elsewhere - yes it is possible and many are doing it). I basically only need to plug in every OTHER EVENING or night between 6pm and midnight depending on usage and I'm a moderate to heavy user (with a lovely 3-5 hours of screen time as well) AND I also have my phone overclocked to 1.8Ghz! Surprisingly, the oc doesn't make much battery life impact at all because the phone isn't constantly having to run at high levels, only in short spurts. Actually, due to rooting and kernel change I'm able to have my phone run as low as 192Mhz during much of its general activity and deep sleep ( which I get a ton of as my phone basically always goes into it when the screen goes off). This saves me A LOT of battery life.
I also use LTE, which is actually one of the biggest if not the largest battery hog, next to screen time of course. But with that being said I only use it when needed and have it turned off when not in use.
As for my peak I was able to squeeeeeze out 87 hours once, on my stock battery BUT that was with some abnormal(for me) measures that really help conservation. Ie, no LTE, under clocked to 1.2Ghz for good part of the three days, much less then normal screen time over the period of which I used it at lowest level with even further reduction via screen filter, I actually used airplane mode during my three overnight sleeps (which I seldom use but if you can hack it, do it! It can really save battery overnight. My current setup basically SIPS MY BATTERY AT 1% EVERY 3.5-4 HOURS OVERNIGHT WHEN IN AIRPLANE MODE), mobile data was off for most of time but did use my wifi at normal level (wifi uses less especially if good signal with few reconnects/scans), used my typical low UV numbers, kept my notification updates/syncs/wakelocks to a minimum and lastly kept my memory virtually clear if unnecessary background apps.
Doing ALL of this allowed me to get OVER THREE DAYS BATTERY LIFE. But keep in mind I seldom do many of these battery saving tips on a regular basis but some do and if you can, they WILL work to extend your life substantially!
To wrap up (this long winded post/reply) I'll give you my general UV mv range numbers and the typical everyday simple battery saving methods I use.
1.My voltage at lowest clock of 192mhz=800mv with gradual (smooth and almost linear curve) increase up to a mere 1200mv at a whopping 1.890Ghz clock.
I use NOOP scheduler with ONDEMAND governor most of the time, sometimes SmartassV2.
My screen off and deep sleep use this lowest 192 clock speed and with no wakeup lag.
2. I use my screen at 0% brightness most of the time (except when outside or in high lighting environment). I use the brighrness widget app to control this as it is easier and works better then stock settings. I actually even further reduce my brightness with Scree Filter App. That app is awesome and often use it solely for brightness control because it has full control and can dim it to basically full black if wanted. Which is MUXH lower then stock control. Fyi I use my phone a LOT more at night or in dark environment thus allowing me to dim screen HEAVILY yet it still is actually plenty bright with ample contrast in dark environments to do everything. This saves on my battery HUGE!
3. I use LTE when needed and GSM/HSPA+ when not. Seldom turn of mobile data altogether. I do turn off wifi when out and only using mobile data.
4. I use Screebl app to have screen turn off when not in use. Its great liitle app. Basically let's you turn down screen timeout to 15 seconds or less so screen is never unnecessarily on but it always stays on when in use due to the accelerometer and it knows when the screen is not flat on table! Its very annoying when browsing or doing stuff where screen isn't touched for long periods and the screen goes to sleep! But this stops that! So its always on when upright or in use and when phone down it turns off immediately.
5. Very important step and can take some time and research but making sure to keep partial wakelocks and apps keeping device awake to a bare minimum! DEEP SLEEP IS VERY IMPORTANT TO SAVE BATTERY! You basically want it to go into that every time your screen goes off and to stay in it uninterrupted for as long as possible. And many users phones are NOT making it into deep sleep due to partial wakelocks and they don't even know it or how to fix it. Not getting deep sleep can unnecessarily kill your battery!
I use a few tools here: Better Battery Stats/GSAM Battery Monitor/Battery Monitor Widget from within System Tuner Pro (which is my also my main and highly recommended tuner app for CPU oc/uc and UV,etc.).
These apps really help to determine what, if any, apps are causing partial wakelocks ( displaying in wake number amounts and overall wake time) allowing you to determine what to do to fix the problem and let the phone gets as much battery saving deep sleep as possible.
6.I'm not big on auto app killers and actually recommend against them as Android ICS does this already very effectively but do keep in mind that the more active background memory that is used, the more battery the battery is drained. So I personally kill unnecessary apps myself from the background whenever possible to save a little battery here and there. Using the apps listed above in #5 can really help to detect a nasty background app or service that is quite possibly unknowingly using a ton of CPU and/or memory, thus draining more battery and also often just slowing down your phone!
7. For those who can use it Airplane Mode is a big saver! Try overnights if wanted as long as missing notifications, emails, calls, updates, etc is alright for you. I seldom use it but it does help.
8. I almost never use my Bluetooth and GPS but when I do that is the ONLY time they are on. They get turned off immediately and really be careful with the GPS in particular because you might be surprised how many things on your phone will use it in the background, sucking your battery!
9. Be careful with sound and vibration levels. Haptic feedback too. I don't do much here but its anotherctip nonetheless.
10. Lastly is treating and charging your battery right! I found an amazing site linked down below in a couple of articles that really explains these batteries and how they work in a very in depth technical level this is still not too hard to follow. Aside from the two links I posted check out the others on the left menu as there is a ton of useful and educational info!

OK I've rambled on waaay too long here. Maybe I'll take this and post a battery savings tips thread with it lol. "10 points"!
Btw I've just received both my 3300mAh and 4400mAh capacity batteries. So I have much testing to do on those too and I plan on reporting back on them as well. Also with screenshots for data and proof...I can and will also post screenshots for all of the numbers and stats I've posted here today with my personal phone/battery accomplishments.
Hope this helps some of you out there because yes this phone can be known for terrible battery life but it CAN be tweaked to SUBSTANTIALLY IMPROVE that life to high standards and keep up with the best of them!

Seems about right. My phone is completely stock and if I really wanted to I could even use it for 2 work days. I usually charge it over night though. I used it for 2 days though while at work, and with 3 hours of screen on time I was down to 7% battery. Around 40 hours on.
I was stocked rooted using Sammy kernel. On demand BFQ. I'll try on demand noop and see if that helps. My screen was about 35% brightness.

Can I hijack a little here? My battery seems to be atrocious. It was okay stock after my first 3 full charges I was getting about 12 hours and 2.5 screen time.
Here is what I've done with my phone since:
Flashed to debloated stock Rom
disabled remaining unneeded apps (example ATT wifi app)
disabled Wifi
disabled bluetooth
disabled GPS
disabled GPS autorun states
disabled 4g
disabled autobrightness, set to 15%
disabled location reporting
disabled Push email with Exchange
disabled Motion
disabled auto google backup
disabled keytones and vibrate on all button presses
disabled touch key lights
disabled Svoice
disabled streaming on googleplay, only plays from memory card
disabled Google Now
fixed the cell standby bug (even though it may not impact battery figured wth)
Uninstalled FB
Set all Autosync accounts and email to sync only once per day
No widgets (only Google play music, Smemo note, flashlight, and folders)
Running save power mode for low power screen, no haptic, and auto adjust screen to blacks
Running mostly black wallpaper, No live wallpaper.
Running medium intensity vibration
I ran battery stats and got a lot of wakelocks from googlemaps and exchange so I disabled the push email and set it to once a day. Google maps I disabled latitude, and shut down the autostarts with gemini.
It's getting to the point where the phone is basically a dumbphone just so the battery can make it while it sits next to me at work. Today I have 48% after 8 hours and 50 minute screen time and 20 minutes of google play (only playing from on SD card not streaming).
Any ideas? It seems like I'm getting less than average.
All I did was also flash debloated rooted stock. Set to top out at 1.5ghz power save on. On demand BFQ schedule. Screen brightness as low as I can to still read. And got 32ish hours. I'm going to try OnDemand and noop like the other guy said and UV a lot more and see how close to 40 hours I can get

Can u link me on the bfq? Having troublefinding what that is.
Also, is that the built in power save that limits the processor or some other software?
I believe if you flash Sammy kernel it has bfq. I am on task's CM10 and kernel and battery life seems poor compared to CM9 or stock rooted

I use my mostly as a media device, but since I'm always near a wifi connection either at home, on campus or whatever, I also use Google Voice and Talkatone for free calls and texts and it works great. I also got two brand new Anker batteries and an external charger and they work fine (my old stock battery swelled and was just overall dead). So I'll use my phone in Airplane mode with Wifi on and I get around 22 hours with 90 minutes screen on time, which is decent, but I feel like it should be better than that. Depending on the ROM, I have gotten as much as 40 hours battery life (which is great) and as little as 14 hours, and this is ALL on Airplane mode with Wifi toggling, so I'm guessing its software/settings related.
i am on a new ROM as of yesterday so I want to make sure I have my settings the best from the jump. I turned off all Location services, screen brightness is low and with the exception of push gmail and google voice notifications, the shortest polling interval time I have for any app is 4 hours. Any other settings I can change to maximize battery life?
One thing you can try using gsam battery monitor to see of anything keeps the phone awake when the screen is off.
You can hibernate apps with greenify and can use dsbatterysaver to kill data on screen off.
Edit: you can also use Romtoolbox to lower max CPU speed to 800/1000mhz and set governor to powersave/conservative depending on the kernel you're running.
Tegrak can help undervolt but the app is a paid app. Romtoolbox has a free version.

To OP:
tt281gt has some great suggestions... I had an issue with conservative governor causing my flacs to skip. I was also running at 1000mhz. I changed to pegasusq and it was good to go. At one point I was using one of Kobridge's tweaks.I think it was Placebo2.0 It was the one where you had to pick like shift1,2,3 or 4 . Shift 3 had some great mods for the conservative gov. It was still great on battery but lost any laggyness. I know he has newer products that might be better than that. Maybe you can hit him up directly with your scenario and he can point you in the right direction. What your asking for is right up his alley!
