What would you guys recommend as the best kernel for battery life??

Yeah I've read that already but I've also read that the motley and omega kernels were the best but this test says otherwise. So I was just seeing what the majority of people would say. Do you have any preference for a battery saving kernel?

Franco's kernel is giving me pretty good battery life. Down to 17% with 4 and a half hours of screen on time and almost 5 days since last charge

Wow, I have about 6.5 hours of on screen time and like 16 hours total since last charge and I have 9% battery left. And I flashed some stuff and rebooted like twice so I'm sure that took up some battery too

I will test one by one

Battery life is much more relevant to how you use your tablet than the kernel. I get anywhere from 5-8 hours display time depending on if my usage is more gameplay or more browsing. The only kernel I actually saw a significant difference in battery life under same usage was faux kernel, performed well but my battery died noticeably quicker.
I now use omega 3 because it gives me faux like performance with stock like excellent battery. I used stock for the longest time, and still would if battery was my ultimate priority, but omega 3 smooths out some games and just about equals stock on battery life. I've never on any device actually had a custom kernel improve battery life over stock. What effects your battery life from day to day is primarily the days usage.

You are saying bull**** im sorry, but you never saw any kernel improve more battery than stock? Oh my god, what world you live?
Im a testing this every day since Galaxy S2... So i know what i saying...
I have the N7 5 days, and i test kernel stock for 3 days and i got 6.5h screen on time, after i installed Franco R42 and used the tablet the same way and i got 9h screen on time, now im testing intersect kernrel and i have 85% with 2h and 30min using the same way always
Resuming, any good custom kernel is better than stock.

my choice is still m+ kernel http://forum.xda-developers.com/showthread.php?t=1937146
I get screen times around sometimes more than 8+ hours with normal use ( web not high power consuming thd games)
This kernel supports man adjustments like undervolting and setting the frequencies.
its works with trickstermod which lets you even deactivate some Cores. Im running undervolted, underclocked
With just two cores without lag or something.
Give it a try

All your opinion based on your "said" usage. Fact is I got 9 hours screen time on stock if I kept gameplay out of the equation. So no I'm not saying bullish*t, I'm saying my results. Just because yours differ and you buy into the "custom is always better" doesn't make MY findings on MY device any less true. Can custom be better? Sure, but it's not fact that it is.
And you say you've only had your 7 5 days, definitely NOT enough time to get real results. Especially since you spent 3 days on stock and less than that on Franco your results obviously aren't same usage scenarios.
Clarification: same usage means about same amount of use in same timeframe doing same activity. Which 6½ hours usage over 3 days is not the same as 9 hours in less than 2.

You wrong
Stock kernel frequecy with 4 cores enable
No UV because Franco R42 not working
No heavy games you are correct.

And 9 hours screen on is maybe possible doing nothing at all CPU heavy!!". Not what most people get doing normal things on their tab. Anyone can keep the screen awake doing nothing really and post a screen saying they got 9 hours. 4 to 6 seems to be the norm. ..no matter the kernel.
That's my story....thanks for enjoying it!

After updating to 4.3, I have noticed that using the stock ROM/Kernel is giving me better battery life than before.
It's equivalent to what I used to get using custom kernels.
Also, I haven't noticed any overheating. At least it is not worse than before for me.
Now before you say "Oh that's complete Wi-Fi use" or w/e. I never got ~ 5 hours of Screen on Time when not on Wi-Fi before either... even w/ PA and Franco and UVing.
With that being said... In my first 24 hours of 4.3 use, I have 5 hours SOT.
Wondering the same thing myself.. to see if its worth flashing 4.3 for the battery life vs losing my custom rom features and adding some annoying things i've seen like constant notifications..
Would appreciate input from people who have already flashed it. Or I could just wait for uxylon to get on 4.3
Going to patiently wait for slimbean 4.3 haha.
Yeah..Battery life is great so far..I started while i had 77% charge left..Still managed to reach 4Hrs sot out of total 23Hrs..

No doubt I'm getting better battery life. Looking like around a 20% increase. I can attribute this to mainly a better cellular signal that I now get. On WiFi battery is roughly the same.

To be frank I'm not seeing much better here than in the "battery impression" thread. Firstly the op has a low score for using WiFi, so I could only imagine his previous experience was even more mediocre, but don't lunge this is just my observation.

Hey everyone, I had this idea, why not post our battery stats at the end of a full charge, telling everyone what kernel and rom we are using what we used the cell phone for, so we can compare some good stats and reach conclusions ?

It is not bad guys. When I read battery would be 2300 I was like damn it will suck but I see google really did a great job here with optimization! Of course we might not get same juice as the g2 but for a 2300 battery I would say is damn sweet! On top of that we got awesome kernel developers like franco and faux which will for sure make possible battery improvements + auto brightness levels seem too high to me. Once somebody decreases them a bit, that will translate into further juice.
Just once I'd like to see a person do a test without any Wifi whatsoever, do it all on 3G/LTE.

Download LUX from the play store, you can set your own brightness. Increases battery life by 20% easily.
So far I'm at 17 hours total ontime, with almost 4 hours screen on time. And I still have 10 percent left.
I will root my phone and disable all Google apps which I don't really need. I think that will make my battery last even 2 hours longer.

Hi guys!
I'm currently using an S3 and I'm hoping to upgrade. My current options are a used Z1 or a brand new nexus 5. My main concern is battery life and screen on time! With my current S3 I get 2hours of screen on time or 2 and half hours of screen on time if I'm lucky! As you can see that, its really bad! With the Nexus 5 users have been able to get around 4 hours max.. Do you guys get a longer screen on time than that?? If so could you please post screenshots/ tell me how much you get?? I know it varies with the amount of usage, but every bit of information would help! Thank you so much
actually it's possible to get a 24 hour long battery life with 6hour screen on time.the stamina and battery saver mode is very efficient.
