The truth about Kernels - Verizon Samsung Galaxy S III

So. question. I used custom kernels on my incredible, so im no stranger...
But can someone suggest a kernel that will increase battery life and performance of the phone for the galaxy nexus.
The problem im finding is there are way to many to choose from,.
For some reason ive been hearing good things about the Lean kernel...
Can someone comment?

I don't think it's bad unless it affects your offline life.
On a serious note, even I was wondering if flashing different roms(flashoholic that I have become) has a negative effect on phone/memory/sdcard/ram/processor/battery/etc life.
I also want to know this... will flashing make your ram less?
or how about... will always doing factory reset will make your ram (or any memory) less?
I myself flash 2-3 ROM's everyday. I think my battery life has decreased somehow .

I flashed a new rom/kernel whenever its available and it suits me. Otherwise, I'll be trying out initd scripts or mods.. It's battery life also had depreciated much. While owning the i9003 for over 2 years, I've gotten the Nexus 7 and 10. I now prefer Nexus's development because only Nexus can get the latest development and you get to enjoy all the developments from big names like Trinity, Franco, Faux, Motley, Rasbeanjelly, AOKP (pub edition), CarbonRom and many more.. To ROM/kernel junkies, you must own a Nexus at least once in your lifetime, no regrets... I highly recommend it...

[Q] Most battery life ROM fo our Pico

Here is my question, what is the rom with the most battery life with normal use? ofc performance will be good (ofc not the best) but atleast for using as daily driver, what is the best rom battery/performance for you?
I don't think it's a good idea to compare roms..I've seen many threads blocked due to this kind of situation.

isnt a comparation topic of all roms, only want to know opinions of ppl of wich rom has got more battery life with good performance
Asking for opinions about which ROM is better in some feature (eg batt life) can be seen as either asking for the best ROM, or just comparing ROMs. Either way, both aren't allowed, so thread closed

[Q] Which Rom Has the Best battery life?

Well, title says it all. Which ROM so you guys recommend for the best battery? Excluding the stock ROM of course! Tell me your SetCpu / Performance Control profile! ( This counts as a question does it?)

There's no such thing. Better battery life is completely dependant on you. Since we all use our phones in our own unique ways, battery life will be different for everybody regardless of the ROM.
That being said there are a few great threads that will show you how to get the most out of your battery on ANY ROM. Look up T.J. Bender's thread The Total Newb's Guide to Wakelocks and/or Insanely Better Battery Life When Idle by Skipjacks. They're well worth your time if you want your battery to last longer.
If I had a dollar for every time I said that, I'd be making money in a very weird way.
Thanks for your reply!

Thanks for the reply. I know the battery varies depending on the user, I was just trying to ask and see if what other people are getting on other custom roms. As you can see there are a lot of Roms in out dev thread, picking out one thats good is hard enough xD. Trying to compare better/ smooth roms with other ones. And btw I was not asking how to improve it xD

Sorry for the weird post...
Jelly Bean Leak 3 :good:
I have tried them all...
Sorry But Kexec doesnt play well with the battery
And non-kexec ones have heavy Bugs
So after a year of wandering and flashing...i came to the conclusion that JB Leak3 has the best battery backup...atleast on my phone .....:good::good:
If you are counting Leak 3 as stock...I have heard JBX 1.0 Kernel gives a long battery life...however i havent tried it personally....So go ahead do some searching and flash any custom rom and then the JBX 1.0 kernel over it...
Thanks! I'll try that!

I tried alot of roms. All of them are really good but with no luck, kexec doesnt become pals with my battery xD. I tried JBX too! I also saw posts that it helps out alot. JB leak can be flashed with JBX?? 0_0 I always thought JBX kernel is for 4.2 + roms...

You're right, JBX won't load on the jb leaks because it requires a based kexec ROM.

That first question has been answered here:

And JBX has been thoroughly explained by the original developer in the JBX thread over in the development section. Read over that and ask relevant questions there. :thumbup:

I apologize for being disagreeable but my experiences with the ROMS suggests there is more to the story then a blanket statement about how much you use your phone determining the battery life you will have.
thank you for your suggestion to look at the jbx thread

No need to apologize. My experience has been that there's tons of things (apps, scripts, mods, kernels, CPU settings, etc) that will make battery life better regardless of the ROM and tons of things (rogue apps, CPU settings, poor data signal, wakelocks, etc) that will make it worse regardless of the ROM. With all of the variables and available options it doesn't seen to me that someone can simply pin good or bad battery life on the ROM, alone.

I think numa has the best battery life till now over the many roms ive tried . .

Hy friends I'm coming from note 3 and I've searched but can't decide what kernel is best for sound and battery I'm not interested in games or something else .I have to say this is so much better that crap touchwiz but on note 3 the battery was good and faux sound rocks .thanks all and appreciate the opinions .overall happy with the decision this is so much better than samsung

kernel wont really help with battery. battery life is all about how you personally use your device, how you personally set it up, what apps you choose to install, and very much the quality of your phone/data signal. all other things are very minor when it comes to battery, including kernel.

Use one or the other. You will cause conflicts otherwise. My bet is on Viper.
No conflicts I use fauxsound with quality and viper4android for the rest of the settings the only thing is that I'm using the driver from viper but no problem sound is great I feel that soundstage is better than what I had with note 3
PS : any opinions on sound on lollipop I know that on l we have support for 24bit 192 kHz

You can't possibly know if you're getting conflicts or not. ...but you will be. Use one or the other, or you may find excessive battery drain. good luck!

Kernel for stock ROM 5.0

Hey guys.. Returned after a long time on XDA.. Was using unrooted nexus since a year now..
Planning to unlock bootloader and get a custom kernel for my n5 currently on lollipop having LRX210..
Which would be the best kernel for stock ROM..?

People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
