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...
I charged my Nexus LTE(unrooted,4 days old) till it was 100% before I went to bed. As soon as I set my alarm I unplugged it to test to idle. Well I just woke up 6 hours later and it was completly dead. I have it on the charger now, I hope i can see the spycpu cause that was main purpose for leaving it off. I do not sleep surf either.
Is this a defective phone?
Wow that's nuts. I definitely never get that sort of battery drain. Are you rooted? Using a custom rom or just stock?

unrooted.
I have to leave for work now with out a phone, I will try to check up via computer (feeling like a dinosaur).
Ha ha I know I feel so bad when I don't have my phone. Maybe see if it happens again tonight. If it does I would get on to the carrier. Have a good day at work!

Are you sure it was dead or you just had a sleep of death? If it truly was dead you definitely have something draining your battery during idle. I highly recommend you turn off your LTE antenna if you haven't already unless your using data intensive apps and you need it, such as surfing or netflix or something. Also, change your sync times to less often, I do every 15min. Sign out of google talk, use wifi when you can, adjust screen brightness, disable bluetooth. White backgrounds will eat your battery faster as well. What else am i forgetting.... Root will help if you can manage to, its incredibly easy especially with the new rootkit out, because you can load francos newest build which has increased my battery 2x, with 25% drain in the last 8.5 hours even with a 1/2 hr of whale tail last night. Also make sure your not running something stupid in your background thats eating your battery like a task killer or battery spy or something, those just rape your battery
If you turn on Google+ instant upload and it has thousands of pictures to upload that will kill your battery in a few hours. If your phone is staying awake because of Android OS then try turning off your GPS.

As noted in a lot threads on a lot of forums, there are some phones that have a problem with the Android OS and the "Keep Awake" time. There seems to be an issue with some phones not truly going to sleep when the power button is used to turn off the screen as opposed to letting the screen turn off automatically when the screen times out. This results in a very high time in the Settings/Battery/Android OS/Keep Awake menu.
In stock form and with every rom that I have installed, my "Keep Awake" time was always about 50-60% of my total battery time. If the phone had been off charger for 8 hours, I'd have 4-6 hours of Andorid OS "Keep Awake" time. This was true even if the phone had been in my pocket unused and seems to be exacerbated by my habit of turning the screen off manually with the power button every single time. I used to never let the screen timeout.
There seems to be two "fixes" according to Franco (of kernel fame). One concerns the camera. Seems the camera is started and then turned off during startup. But in so doing, it leaves a sensor active and this prevents the phone from actually going to sleep. So he recommends starting and using the back button to go back to the home screen. The other is DRM Protected Content. He recommends this be disabled or frozen. A third, that I don't believe I recall seeing him recommend but that I have seen on his thread at XDA (down for blackout right now) is to disable Maps.
I have done all three of those and my Keep Awake time has gone from 40-50% of my total battery time down to a few percentage points. I mean if I don't use my phone it will now show less than a minute of Keep Awake time per hour.
Good luck
My VZW nexus can idle with moderate use on constant LTE and get 15 hours with out issue. Hell I have even gotten more so check google+ as suggested. If it went dead on idle with nothing running constantly to cause it than I would say your phone and/or battery is defective

Ive been getting good battery life, despite my awake time being around 6-8 hours at the end of a charge. I tried the camera close but that never helped, I've just disabled DRM though. Also, GPS locator has been associated with this, which is probably what you meant by "maps". I just turn off my location unless i need it for navigation in location settings

It has to do with digitally protected files, music, etc. One time I went home screen/menu/settings/apps/all/drm/disable. The last time I did it from Titanium and pressed the freeze button for that app.

Hi, how its your average batery life?
I have never really run any tests for it, but i've left the tablet alone for a few days, just sometimes checking for Firmware updates, and it barely lost 30% (maybe less, can't recall).
with no live wallpapers on mine lasts a few days with moderate use (checking email, rss, news, maybe playing a couple games)
Well i got the Archos 80 G9 250 gb version and mine lasted for 4.5 hours of continuous video playing , screen brightness on 50 % . The problem is that even in deep sleep it looses battery . How can it last for a couple of days i can't understand , any hint ?
I have the flash version, maybe that would make a difference. Check the wifi sleep policy, and make sure it turns off during sleep. Also, I keep bluetooth and gps off. perhaps try that?
I have the basic 80 g9 and for just using it the evenings it will be happy to last for 4/5 days with email, twitter simple games etc. When I've travelled with it in 3 hours of video playback I lose about 50% with no connections such as WiFi or 3g.

Well actually i didn't checked that but i have the impression that mine looses a lot of battery in suspend mode .... I always shut it down and even like this when i start it again its not the same as it was .... maybe the actual starting process uses a lot of power don't know
Could be a rogue app. My phone was like that for ages and it was getjar nit letting the phone sleep properly. Try better battery stats or something similar to see if a service is causing partial or kernel weaklocks too frequently

The 80G9 1.5 GHz turbo I just started using is to new for me to get an idea of run time, so far about 8 hours of mixed use, on my 8gb classic would go between 5.5 to 9 hours depending on use, in deep sleep non use, it would go for days at least
What works for me, on best battery management, I like to put into deep sleep every time I put tablet down and plan not to use for a few minutes or more (this turns of Wi-Fi, screen, and stops mosts things from running) it always wakes up with a quick power press and Wi-Fi connects within a few seconds
I use normal sleep (same as when it times out I think) for quick pauses in use.
normal sleep for when not using but charging if I want to hear notifications for email, Color Note, Evernote etc. (Wi-Fi on)
If I want the quickest charge, (not using, overnight etc.) and I don't care about notifications (Wi-Fi off) I use deep sleep. edit, to be clear on notifications, my Color Note notifications work while in deep sleep
Turn off for longer periods not being charged/ used
You can set when Wi-Fi disconnects by going to:
settings, Wi-Fi, Wi-Fi disconnect policy (I have mine on never for now)
*and of course, use the correct cable and charger!
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

From what I know it lowers the CPU clock speed and decreases brightness. All with the intent of saving battery.
I read that while it DOESN'T limit the CPU, it does lower the brightness and cuts out your data/BT/location/NFC in order to preserve the little bit of battery.
Edit: And syncs.

I don't think it actually does any of that though. I have been using it a lot the past few days half on half off. I still get all MMS and emails right away plus my photos are syncing with google. My brightness doesn't change (auto or not). plus I have BT and WIFI on all the time for smart watch and of course data usage . Maybe the processor, but im not even sure of that. Guess I could do benchmarks with it on and off and see. I just feel like this feature is doing nothing at this time. On my nexus 5 I could really see the processor throttle and brightness him with battery saver.

Mine only does that under 15% battery. Seems like its doing nothing over that.
Sent from my LG-H815 using Tapatalk
The default is under 15% and when it kicks in, i definitely notice a difference in the phone.
You can change it to immediately from 15% and i bet you will notice a difference at any battery percentage.
Cpu speed is not affected, just checked this.
Brightness was indeed cut off considerably, haven't checked for other things yet :good:
I figured out why it wasn't working for me. Simply clicking the icon to green in the pull down only enables it when it gets before 15 percent. Didn't force it on now like I thought it was.
Why is there so little discussion on this feature? I found very few threads on this and this was the most active conversation even though it is so old. I found out today I could enable this feature at anytime, not just at 5 or 15%. So I have it enabled at 100% battery and testing today. Upon enabling battery saver mode and restrict idle apps, the screen immediately went dim. I turned it back up slightly. I also noticed apps acting different. Toggling between apps is quicker and the animations are gone. Also, I'm using chrome and it's acting different. It's hard to explain, but if I'm navigating from one website to another, it is feels like it is refreshing every time, it doesnt feel faster. Im not sure what it is doing but someone with more experience will probably be able to pinpoint exactly what is happening. It's not standard chrome behavior.

Not sure with the Chrome part of it. I use a different browser. With FireFox everything feels about the same as before.
I also noticed the animations are removed so there is no fancy domino effect or sliding going on. It's all instant and to be honest it feels heck of a lot quicker this way.
Screen is much more dim and is extremely conservative for the most part.
Clock speed is the same. Although I wonder if there is some sort of under the hood change such as MPDecision switching over to battery saving mode. It personally makes no sense to leave it as is considering in the past it use to cap the clock speed.
So using battery saver today along with restrict apps in background, the former definitely shuts down background data. I noticed Google play store not authenticating paid for apps. I had to go to the play store to launch the app and re-authenticate. That is where I received the warning that background data is off. I have a weather widget and that does not appear to be updating as that uses background data. I have a barometer widget and that does appear to be working as that uses sensor data. All that is required to re-enable background data is to uncheck restrict background apps under the battery saver mode. As of right now, I am at 71% battery and 2 hours 14 minutes screen on time, 3 hrs 53 minutes on the battery. I'm mostly using chrome while screen is on and podkicker and listened to about an hour of audio and a little bit of teamspeak usage with my Bluetooth headset. Brightness is at 37% which is pretty dim in this mode. I'd say it's equal to 15% in regular mode bit good enough to see.
Update, I went all the way to 25% battery remaining yesterday and I had right at 5 hour SOT. In my opinion, this mode is not worth the hassle. Background data is off and that breaks a few things. Screen is pretty dim and I ended up turning it up anyway. I have had similar battery life in the past anyway. I have had 7 hours 20 minutes of SOT before without this mode on and all my widgets working. I'm going to leave this mode off.
It saves battery
