I'm runnin baked snack 1.6 w/ ultimate kernel...and I have ridiculous battery drain!...I have autimatic task killer, setCPU (set @100mhz-800mhz w. Conservative governing), and I'm well seasoned in the usual battery saving how to's. When I check Spare Parts and go to "Battery History" under "other usage" I can't get rid of the 100% awake time...evn though my screen may only be on for 25% of the time.
If anyone has had and solved this problem or can offer any advice please LET ME KNOW!

Make sure you are not running applications that will constantly poll the system for information. If setCPU is set to scale based on system load it may prevent the device from sleeping because it will be checking the system state too often.
Another commonly overlooked cause is from Battery Monitors. These can often poll the battery level too often preventing sleep as well.
If all else fails backup your device, wipe the data, clear the cache, and reinstall programs one by one.
Bottle of Rum. Makes anyone sleep nicely.
No need for Automatic task killer
No need to underclock the CPU to 800. This might give you like 5 minutes longer battery life per day.
Check the Running Services and see if anything looks out of order.

right but if you can set it to auto underclock to 200-400 when in standby that adds up. Also juice defender

Good suggestion but the only problem I have with that is it causing my phone to shut off because it's already undervolted, I have it on conservative all of the time and in the app "Android System Info" it always shows me running at 200mhz from 70% to 90% of the time anyway.

I don't have any battery monitoring apps except bat stat widget...but nothing like battery indicator pro or a full on application. I'm running the Emotionless Beast theme with the percent mod in in the battery icon...I've heard rumors about this bieng a potential problem....could that be anything?

I stay on top of all my running application through the phone's "running services" tap in settings and through the built in task manager...only Launcher Pro and Widget Locker are left running all the time.
Use Overclock Widget instead of SetCPU. I find mine to be most stable at 400-1200 on, 400-600 off. ymmv

Yea I think the default governer that comes with the Baked Kernel is set to performance...which I know for a fact is detrimental to the charge life of the battery...and can you underclock you CPU with Overclock Widget?

Yeerp!!! Ezalis...you saved my phone mane....I backed up the whole ROM re-flashed along with the Kernel, wiped like 6x Data and Cache...and put everything back on one by one...worked like a charm, my % without sleeping is sittin pretty at 12% thanks for the help!
Not a problem, sometimes you just have to give it a clean slate to work with.
hey guys, im one of those sufferers of poor battery life on my nexus ever since i went to ics and i was wondering if you guys could share any of your own tips for saving batt.
personally i always turn off the auto rotate and disable g+ and nfc.
flash custom kernel..
matr1x kernel, TEUV ..
Or..flashing Bugless Beast ROM...
No matter what ROM/Kernel you flash, the biggest battery drainer of them all is the screen. (Evident in the battery history in settings.) Setting the brightness as low as possible will help battery life dramatically.
If you have a SAMOLED display, black/red backgrounds help save battery life tremendosly over any other color. (White obviously drains the battery the most.) For this reason, if you have AOKP or CM9/CNA I recommned flashing the Black Infinitum Theme. Black framework and inverted apps!
Also, other rules apply such as not syncing as frequently, reducing rogue apps that produce wakelocks (i.e. not letting your phone enter DEEP SLEEP.)
Download CPU Spy and check out the percentage of time your phone is in DEEP SLEEP. Mine is usually in the 80-90%, depending on your usage.
Check out Bedalus' battery thread on kernel settings: http://forum.xda-developers.com/showthread.php?p=22126792
Also, DO NOT fall into the trap of using task killers. All they do is consume more unnecessary CPU cycles. What about freeing more RAM you ask? Freed RAM does not consume less power than used RAM. In fact it may use more power when you want to boot up that app you just killed. Instead of fetching the data from RAM, it has to reload the contents once again.
However, I do have an exception with Juice Defender. Personally, if you want your email to sync every hour or so this is a great tool. Instead of leaving your data on, JD will turn on for a few minutes every hour (or any other user defined interval) and allow any apps which need data to sync. After this short period when it is on, JD will automatically turn off data for you.
1. Flash a custom kernel. I like matr1x best, it gives me great performance and awesome battery life.
2. Know what uses the most power. As the guy above me said, it's the screen. Lower the brightness. The next is 4g. turn it off if you aren't using it. The GPS and 3g are next. Use the power widget and only turn them off if you NEED them. Always use wifi if you can.
3. Set your CPU for battery savings. Download NS tools. Set the governor to ondemand. 200 minimum, and 1000 max. LiveOC to 105. Deep idle off. Leave the voltages as they are. They aren't worth playing with much, as the Mart1x kernel is already undervolted.
3. Turn off autosync. It drains battery. I can put my phone down overnight and it will loose 2-4% when this is turned off. Just remember to refresh things yourself!
This is all I have. It will improve things a lot!
1. use 2g only and switch to 3G when high speed is needed. you will notice huge difference in battery savings
2. use matrix kernel with conservative governor. Apex is a good ROM out there as of now
3. remove auto rotate and set the screen brightness to low - dont use auto
4. turn off NFC
Turn phone off. JK. Best of luck on saving juice. I agree with everything that has been said. I use no screen saver. Black background. I am using the latest CM9 w/Air kernel. (Matrix is good to.) I use it with about 2.5Hours of screen "on" time. 21-24 hours. I never charge the phone and I swap the batteries.
I use a battery saving app called "GreenPower" and set it to only sync my email once every one hour, whenever my NS' screen is off.
Also, I don't use memory hog apps, like Facebook and Google Maps, that keep running in the background; I only use their web-based versions.
You could also try "calibrating" your NS' battery by draining it to 0%, then charge it all the way (non-stop) up to 100%.
Use task manager, which is free on the app market to kill battery intensive task automatically

Don't use task managers. Android manages tasks fine on its own. Task killers are known to kill system processes which take a ton of power to restart, amongst other things. They're overall not good for your phone unless you are on Froyo or below lol. Also look into the app Auto starts and freeze apps that you don't use. Alongside other suggestions here you'll save a ton of battery. Disabling animations and vibrations help too.
I get about 4 hours on-screen time with this set up, and a whopper of idling time.
Nexus S (GSM i9020a)
AOKP (Milestone 4)
Air Kernel (3.45)

I definitely agree with several of the posts here. Definitely root, rom, and install a different kernel. 4.0.3 based ROMS I have found don't have as good battery life as 4.0.4 based ROMS..

You can also download BetterBatteryStats. It can tell you which apps are consuming more power on your phone.
If you are on ICS 4.0.3 Stock, you might want to think on installing a custom ROM based on 4.0.4.
Disable background processes (Whatsapp, FB, Twitter, etc). If you are not using Wireless, disable it.
Also, if you use apps which contains ads, it has been found that these ads will consume about 70% of the total power consumption of this app. An adfree might help on these situations.

This, basically. I think we should have a popup saying "BETTERBATTERYSTATS" as soon as someone types in the word "battery" into a thread title. Maybe force them to download it before proceeding, too

Agreed! This sounds like a good idea
OK,
I was not too impressed with the new icon and look of 2.6 but...
Now that the visuals have been accepted, I see a definite improvement.
One being memory, as I get 550mb of used memory after hibernation has been manually completed, or automatically in lock screen.
Before I would get about 650mb used on average.
Speed has improved as well with the new xposed framework. I think it is mostly due to how the xposed modules are loaded, and how well the apps are hibernated.
Though, Wanam xposed still has a few bugs that have been ignored by the developer, the ability to change button settings in Display are still hidden. You can disable wanam and reboot to change the button settings in Display, and enable wanam before rebooting to get around the limitation.
Kb/s seems to lock now... before it would randomly go away during hibernation or reboots, thus needing to go into the module and toggle the setting.
So far with Xposed getting better and better, having a fully functional stock ROM does not mean your missing out on options and performance.
Here is a list of Xposed modules that I run on 4.2.2 that work very well.
3dot Mod
Burnt Toast
Complete Action Plus
CrappaLinks
Disable Location Consent
Downloads2SD
GoogleOfflineVoice
Greenify (Experimental Features)
MinMinGuard
Network speed indecator
Play Store link in App info
ReceiverStop
S-pen Only
SPDY
Secure Samsung Clipboard
Wanam Xposed
YouTube AdAway
Battery improvement update!
OK I did an hour test using a 720p video file running MX media player, set with volume at 50% on the speakers, and 30% brightness with Power saver Disabled. The settings are good for personal use in a quiet room with adequate lighting.
I was able to watch one full hour with 10% battery drain. WIFI enabled, and everything but OTA setup for syncing. My apps are setup with a dummy google account that has sync disabled, so all the data and email are with my proper accounts.
This is a great improvement, as I always had to use power saver enabled to get that type of battery usage.

I use it to get the best battery life possible. It is the only way to disable Samsung's DVFS, and allow for Greenify to fully function to maintain RAM usage.
I get 550mb used after tablet wakes from sleep. I can go at least 8 hours on a charge doing normal activities. With power saver off I get about 5 to 6 hours on usage time.
It all depends on what apps you run, and how you use your tablet. Heavy video editing, GPS and rebooting will drain the battery down faster.
I recommend, never turning off the tablet to charge. If you need to reboot into lock screen and then charge while in hibernation.
The reason is it takes 10 minutes for the OS to settle after loading. It can consume up to 6% of the battery once started up and fully charged.

I donno... Nobody has posted real world specs for what they get with 4.4.2 or modded 4.4.2, though custom kernel ROM will be faster if overclocking the CPU. Since there is no real good heat transfer to cool the CPU / GPU, the batter gets beat by the heat and current drain.
1.6ghz does a fine job when the apps you run are for the most part bug free. The most recent BBC Iplayer/media player, MXplayer, Netflix all do very well with cpu / gpu management along with image quality.
I just noted that Google fixed some issues with a few apps, as I was going to comment that last weeks Google apps have a memory leak or keeps google services running. Now since they fixed it a few days ago, I get 550MB used after wake up and ready 95% of the time, when for a week prior I got 700MB average. And that is with sync and wifi on.
I am ol skool, if it works don't break it, use it.
I don't do benchmarks, as they have little to do with real world performance. It is your apps and how you setup your tablet that makes all the difference.
Hi all,
I've been trying to squeeze as much battery as I can from my Note 4, I've just got GSam to monitor my processes and see what may be eating up battery.
Within the app it has a section called app sucker, under the header android system there is a subsection called "silent logging" along with many many others, does anyone know what this is? Can it be killed or if it's even needed? There are another 30 something processes as part of android system.
I'm not rooted and afaik I simply have to put up with these things.
Battery life isn't great for me at the moment which is why i'm digging a little deeper to find the culprit.
Any help would be appreciated.

Yeah, it can also be a reason for sure.
But, the 3rd installed apps, the services of the bloatware, or the background cached app, it can also make ur device drain more faster.

+ Flash Evira kernel 2.0

It seemed to me that VoLTE might be causing battery drain on my Note 7. After a few hours of not using the phone, where I'd normally expect the battery level to drop by 0.5% an hour, it was much more than that. Although I have to admit that I sometimes used Whatsapp Web in those periods and one of those cases might have been affected by that. I'm also using 2 SIM cards, both on 4G but the other carrier does not support VoLTE, so it was always off.
So to test things out I've had VoLTE disabled for a few days now and idle battery use seems to be more economical. This is inconclusive, I have to test with and without VoLTE for a bit longer, but have you guys maybe experienced this?
Regarding the Li-Po battery, as it is non-replaceable, I started taking better care of it than on my previous phones. I use AccuBattery to notify me to unplug the charger before the battery reaches 80%. Also, I tend to charge it from 15 to 75% or so whenever I don't need long battery hours. I recharge fully if I know I'll need a lot of juice, but the phone's battery is quite large, so I'd like to preserve it when possible. Battery University says frequent deep discharges (nearing 0%) are harmful to your battery, while AccuBattery says the only issue is high voltage (when the battery is at 80–100%). They coincide in the high voltage issue, but AccuBattery tries to disprove BU's claims about deep discharges.
To be on the safe side, I'm trying to keep it in the middle for now. What are your opinions about this?
My phone battery was at 27% before I sleep. I put it in economy mode and when I woke up (4 hours later) it was 12%.
I desativate all my background apps, Facebook, Whatsapp and even so it is drainning so fast.

Xiaomi Service Framework is a bloatware that Xiaomi mainly uses for data gathering.
Also MSA can be disabled too.
