Any idea why my phone runs out quicker when using power saving mode? With power saving mode on, 17 hours with 4.5 hours screen on. Yesterday 1d 8h 5 hours screen on with power saving off.
Using cleanrom ace and adam kernel 2.5

It could be the kernel? Power save mode is nothing compared to a well built tasker profile or two. Or even a good CPU profile.

Maybe you have used your phone differently on those days? More screen on time? With higher brightness? Maybe the tasks you did were more battery draining (other games, video recording.... or something else...). Battery saver mode sets max cpu frequency @1000Mhz and that's it. If you check what is draining battery in your phone you will see that at times (full brightness) the screen eats up to 70% of energy so the savings from cpu are negligible.

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.
Hi Guys!
I am facing a very extreme battery draining situation...
Something is keep waking up my phone while my screen is turned off.
Is there any good app out there I could monitor / Find out what is constantly waking up my phone? I can not find any good app for that.
Thanks for your help in advance.

Get yourself rooted and grab SetCPU. I have a profile set on that which underclocks my CPU when the screen is off. Doing this GREATLY increased my battery life.
I also use Tom Hubalek's Battery Gauge Widget to help me monitor my battery. But, after using the RCMix S v2.0 ROM and calibrating my battery (and the mentioned CetCPU settings) I get a good day out of my phone with a lot of wifi and 3g usage.
Never had any issue so far with my battery... I am checking battery usage in the settings menu but it is not enough. Need to see what exactly using my battery 'cause its unacceptable to drain 60% in 5 hours... The only thing I can see that something is using (waking up) the phone even when the screen is turned off...
I am using SetCPU as well with Smartass governor... can not be the problem...
Also set a profile for screen off - i have it set to 245min-245max smartass. It seems to save battery more than just set on the main screen.

Have you tried changing the Wi-Fi sleep policy? Also, pocket mode and fastboot, if you have those options.
My SetCPU is set to OnDemand. I thought Smartass was unstable and gobbled more power than it should? I dunno, though, I use whatever the ROM developer uses for the ROM; I don't change anything.
But you're right, my phone has lost 61% in 14 hours. 60 in 5 is wrong.
I think JuiceDefender has some of the features you're looking for, though:

Ach, I have mine to 245-600MHz when the screen is off. Any less and my rom is lacky when the screen wakes. Had the same settings as you for other none Sense 3.0 ROM's though. MAJOR power saving. If you leave your phone downloading, though, the screen off profile kills the download rate.
Check it out, upload a file to your phone via wifi, turn the screen off and watch the speed plummet to about 100kbs!
EDIT:
Anyway, I had a massive power saving when I used this ROM:

Dialer
If you're using a gingerbread based ROM, it could also be the dialer. At least it is for me. Sometimes he just goes crazy and I have to reboot the phone. Apparently the dialer checks the phones proximity using the sensors again and again.

Juice defender and Setcpu are in the same basket as task killers.
If you are using Smartass you don't need any profiles. Check your widgets, probably you have one which updates every second and kills your battery.
Does this Battery Use look normal? I'm mainly worried about "Android Os" keeping the phone awake the whole time. This is the first charge after the initial charge drained.
Looks pretty normal to me. Are you using Auto Brightness for your display? Big drain on the battery if so. Try disabling Auto Brightness and adjust the slider to about 20-30 percent and see how that works for you
Normal for first charge. Let it cycle a few times. Check under settings/developer options/apps---don't keep activities. If it is checked thn the OS will run a lot refreshing and deleting app data.
I'm not using auto brightness, just using the power control widget on the half circle mode. Nothing is active/selected in developer options.

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!

On Stock battery - Kyan Rom/Ktoonez kernel (at this moment)
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!
