I recently flashed CM9 3.x kernel rc3 (http://forum.xda-developers.com/showthread.php?t=1492461 ) and installed playerpro. And when I listen to songs phone overheats and battery drain is through the roof. Display is eating almost 90% of battery even though its off. Any idea anyone?

display always eats all the battery, that's normal behavior. Try taking it off full brightness or automatic brightness and set a level yourself. Dimmer is better. Overheating due to overclocking, usually, check what speed you're running at.

Display is off when playing music so display shouldn't eat 90% of battery. Plus I noticed that it isn't only Playerpro. I tried Apollo music player and it also give that issue.

What's the fastest way to drain a battery down ? I want to cycle through a few batteries and see if there's any improvement in battery life.
Play a game on it with Bluetooth and Wi-fi turned on, with the screen at maximum brightness ?
Do a massive amount of downloading from a 3H/HSPA service if your data plan allows you to do so ?
Depends if you want to leave the phone unattended or not while you do this.
Best way to do it unattended and without sound would be best. Right now I have Wireless Hotspot On, Bluetooth On, and I'm recording a video.
Make sure screen is on maximum brightness and set the screen timeouts as high as you can.
Use the video camera. Also try playing or streaming alot of videos.

What I did:
Get the PhysX smart wallpaper and max out the settings (this will max out your cpu)
Screen brightness all the way up.
Turn on GPS.
Turn on BT.
Turn on Flash LED.
Download a huge file over wifi.
Disable locking/screen dimming.
the fastest way to drain IMO, FUll screen brightness, buletooth, Use Wireless Data (not-wifi) to stream Pandora, or Youtube or other videos continuosly
Record HD video with the flash constantly on, and just set the phone to the side. Or set up a trip in the google navigation app, but just let the phone sit. The GPS will eat up the battery pretty quickly.

play an albums worth of music at full volume.. dont get cute and use headphones now i want you to appreciate that single powerful G2 speaker for all its worth... !!!
Im running MIUI and I notice in the battery use "media server" is always second under display that uses the most battery.
I listened to some music through my phone but maybe 15minutes worth?
It seems to drain my battery, in just 4hrs Im down to 55%- with everything off, cpu clocked to 614mhz, vipermod -50mv. Ive just been texting thats it. I have vibration and sound notifications off.

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!

http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
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

Hello,
Lately, my note 8 started to feel warm while I'm using it...
So I decided to watch CPU temperature using System Tuner:
https://play.google.com/store/apps/details?id=ccc71.pmw
First, temperature of the atmosphere here nowadays is about 35c to 40c...
for my note 8:
In idle mode, temp is about 40c, while normal using (wifi off, bluetooth off) like watch videos, using apps,
CPU temp is about 50c and battery is ~38c to 40c
sometimes while gaming, CPU temp could reach ~60c
The tab from the back left side is feeling warm
Is these temps normal??
What's your readings?
Note: I'm rooted on stock 4.2.2, and I didn't modify anything..
I just set the max freq at 1GHZ after overheating

Removing, disabling, or freezing Google Play Music will fix battery drain and temperature issues. Though there are thousands of apps that are buggy, since everyone has different tastes there is no real way to point out exactly what app outside of Googles Play Music that is causing drain without going into system and looking at battery. The top two items listed are the cause of your battery drain. Display should always be on top unless using GPS, Games, or Media without power adapter. Google's Play Music will cause Media Adapter to index in back ground. Depending on media type and media name, Media Adapter will run for 30 minutes to hours on end draining battery as well. 4.2.2 has a bug with media names, So using Windows or Apple's media management to create folder and names can be your issue as well. Search for any media with "_" in the name or folder.

Google play music is disabled long time ago.
I'm also aware of the media storage drain issue...
That's why I wished to upgrade to 4.4.2 to end the media drain issue.. but kitkat seems buggy too as many users confirmed that.
Also, I've no battry drain problem, it's just overheating!
My battery can last for about 8 hours without charing
ONLY OVERHEATING

No, my warranty is void...
I downloaded 2 different apps to check the sensors in note 8.0
it doesn't have temperature sensor at all!
How system tuner could give me CPU temp?? or it's just fake?!
I've had my M8 for 6 months now and just did a factory reset to improve performance but the battery is still bad for me. I start at full at 8am and my phone is dead by 4pm with normal usage, about 7 hours total. No apps seem to be hogging battery. Android, the default processes, and the screen take up most of the power.
App usage
You do realize that your NFC and bluetooth is on right?
I'm also suspecting that a app could be the cause of it but I highly doubt so. There's a possibility that your device packs with a faulty battery to begin with
Mine was bad too, I uninstalled every unneeded app, screen brightness never goes more than 40, battery saving mode on all the time, wifi bluetooth GPS etc on only when I use them, greenify quite a few apps too and all ads are blocked. I also wiped battery status and let battery has a fresh start. I don't play games, only use it for music, web browsing, emails, social networking; I am a medium user.
My phone can go from morning to midnight with one charge and that's all I need.

WiFi, Bluetooth and the such use little battery, at least according to GSAM. GSAM also doesn't say any app is hogging battery.

I'll try that. My brightness is already set low with Lux and I only use my phone for Web browsing/social media. Unfortunately I can't root on 4.4.4 right now so I'm limited in what I can do.

With Lux, you are using auto brightness, which is always going to be an extra battery drain as the light sensor is being constantly polled. Ditch auto brightness, and just manually set it with auto "off" for best battery.
