What's yours?
Okay I'm on stock kernel with .42 firmware, rooted and locked BL and my record is about 1 day.
Your battery life is so good because of the 10% display brightness.
Most of use, including me, use auto brightness.

Do you really think auto brightness is profitable?
I have the brightness settings in the notification bar and I think so it's the best.
I'm not a fan of auto brightness.
I'm on stock kernel too with .42 firmware, also rooted and locked BL. With supercharger.
My record is 1 day, but i use autobrightness, and have music playing almost all day. Wifi on, data on, and like 20~30 min on calls per day.
i do have switchpro widget with a brightness toggle set to 10% and 30% so it's actually easy for me switching my brightness settings... and yea i also have the brightness slider on the notification bar but i don't use it that much...

Hi, i just noted .. every time that i see the battery usage the most percentage is for the screen!! (41 % after 21 hours) is this normal??
i have disabled the animations and other effects leaving just the bravia engine
Yeah the screen is the biggest battery drainer by quite a bit. Try turning screen brightness down or put on auto if you havent already given that a go

Don't worry much about it, it's normal that the display is always on top in terms of usage stats, it's ON most of the time coz we are using it(unless for music wherein display can be OFF).
If you actually want to minimize the battery drain due to display, just set the brightness as low as you can handle(i set mine usually around 30 to 40% brigthness only).
I'm actually surprised that you have low display usage in 21 hours, you must be a very casual user only. As far as I can remember, my fone never last me a day since I bought it. Coz I used 3g/data most of the time, surfing net and messenger.
hmm may be a dumb question but, how i can set the brightness on auto?
I use the Power Control widget on screen. The three options are low, auto and full brightness so its just a case of cycling through each. You will know when youre on auto if you put your finger over the ambient light sensor you should see display adjusting

hmm on android assistant appears "Light sensor not avalible" .. it's possible that my arc doesn't have the light sensor, it's a prototype after all
Not sure mate, maybe. Have u tried a reboot?
Sent from my LT15i using XDA App
Yep still "not avalible" ..
A last question, this arc (just as i said) it's a prototype, a very complete prototype. I just wanna know if this device is Sim unlocked (being a prototype). Or if the bootloader unlock can unlock the SIM too, i want to change of carrier.
please tell me when your battery is almost at the end, check how long was your screen turned on? i get around 4 hours, brightness 30-40%, with auto rotation, bravia off...
Hello all
I'd like to hear from you what battery saver do you use. searching into the market I've found green power, juice defender and so on, but which is (for you of course) the best one?
I'm looking for something that allow me to turn off data connetion when the screen is off and turn it on after a specific amount of time for gmail and other programs notifications.
I'd like to hear your opnion.
thx in advance
regards
As far as I know, Juice Defender would be a good choice.
SetCPU is very nice:

Neither.
I tried juice defender and it seemed to use more battery on me. I just use setcpu and turn of only on mobile data in phone settings. data switches of when phone a sleep.
you should install tasker as this can do pretty much anything you can think of.
i run a task that runs each time i unlock my phone and it sets the screen brightness to 15%. this will save alot of battery as the screen is the biggest killer.
nice 8) thanks, I will try!!
cheers

What about when you are in direct sunlight?
Doing anything manually is not an acceptable solution for me. Only thing that works is editing brightness levels within framework-res.apk which would allow brightness to go under 30% (which is the lowest if backlight on auto).
I have another Tasker task via a dock icon that sets the screen brightness to maximum when I need it. When I receive a call the brightness also goes to maximum automatically.
Thanks brivs

Just wondering if the auto brightness on the HOX is worth using ?
I have found on other hand sets apart from the Iphone that it ends up using more battery.
So just a basic question do you use auto brightness and if not what sort of level do you have brightness set at ?

hmm, now that you mention it. Putting it on auto actually may draw more power since it always has to adjust itself depending on the light in the environment your located in. I used auto all the time and I get HORRIBLE battery life, cant even get through half a day so I put it on around 40% or so now. I put it between the C and the B in the Automatic Brightness text and I use medium font size. That should be around 40%. Going to report back later to see if it saves battery or not.
Well I have been using around 40% myself for a while now but was reading somewhere that auto brightness is better but I wasn't sure how accurate that information is.
Does the font size have anything to do with battery life ? I have it set to small at the moment.
Auto brightness only works if they do it right, which is to say that it properly sets brightness for a given situation. (100% outside, 0% in darkness, and properly scale between the two extremes)
Yes but on this device is it worth using will it save you more battery life then just say manually setting it at say 40%
For Auto Brightness i use the App "Display Brightness" from Market .

Auto brightness actually saves battery. I lose battery even faster than usual when setting costum brightness even when it's way lower than 50%

Really? I guess I'll do some testing do you notice a major difference? Cause setting the brightness myself I keep having to change it for when outside cause if to sunny can't see screen properly

I recommend using auto brightness. It really does save juice unless you put the screen on really really low brightness I guess but that sucks because you can't see the screen

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

my zen if im using with cell data off and lowest brightness (which i feel is still too bright) and letting dragon blaze run for about... 1 hour from 10:20am-3pm and then leaving the screen on i went from 94%-70%... is that good?
i find at work if i only turn the screen on to check the time and turn screen back off thru out the 4 hours i use 3-8%
how long "should" it be lasting if i just do web browsing, pandora, or gps?
again, thanks for reading -hugs-
off-topic: is there a way without much tampering or using another app to bypass the brightness limits? because as I already gave my opinion "i feel the brightness even at lowest is still tooooo bright"
You can use the app "Screen Filter" to dim the brightness below what the lowest is. I use it at night a lot.
Consider your screen on time. I get about 4-5 hours of screen on time before it dies. On standby, it drained about 5% over 6 hours when I didn't touch it at all.
