Did you try with Stock ROM??
i always do the 2times reboot phone after flash new custom rom as mention by eyebee on rocket rom.. i never experience the same problem like yours.. abyssnote some time make my SGN hot, then i flased FM kernel, my SGN temp became normal..
Which rom and kernel are you using? I feel that my note used to heat up a lot more when it was completely stock. Try undervolting your cpu. I am on rocketrom v19.1 and abyssnote kernel v3.3 and have minimal heating issues.

yeah with RR19.1 abys3.3 it still same still hot T_T , like my explaination in first post. i think i must try in stock rom , decreas my battery until 0 n full charger

[Q] CheckRom V6 & What kernel?

Guys what it the best kernel for checkrom V6?
I mean.. i want advices BUT why did you made such a choice?
For me it is Franco hands down. Tested v2, v6 and the latest 'test' one (this will become v10 tomorrow or the day after, judging by the users' comments), and all proved to be smooth, fast, stable and easy on the battery on my Note.
I would second Franco kernel also. Been using it since v6 had no problems with lag at all. Battery life with this combination seems good as well.
Now this is a good start
I have been in CF ROOT for XXLC1 but i dunno why i feel the stock kernel is a little bit lagged in menus!
Will try Franco Kernel
Thanks for your replys!

Franco 9.....pure awesomeness !! Best battery backup m getting by using it. Earlier tried Abyss 4.2 but got a high battery drain !
Go for Franco !!!
but doesn't changing the kernel change some supported features in the rom ? like ntfs support for instance ?

Check the changelogs of the kernel you are about to use it will give you all the salient features and changes that it has and can happen!
Cheers!
Hey guys,

Yeah of course! I have it installed on my phone. just go to the inbuilt kitchen (update it to the latest version from google play store) and download the file given there under the themes section. Its version1.1 as of now. And install it in recovery !!
Cheers! Hit thanks if it helped!
I was using stock CF-Root and it was fine, but the battery drain was a bit higher vs V5 CheckROM. Installed Franco and its running great, 1.5% Per Hour idle.
was using checkrom v6 with Franco's test kernel. Seems like its draining battery more than stock. Gonna verify it over the nxt few days by using stock
Also on Franco test kernel.
Also on franco kernel v9, works like a charm. Good battery life but no as good as CheckROM v5 & franco v6
For me Franco kernel cause constant sods.
I keep trying a newer versions and still same issue. This problem doesn't occur for me on other kernels

Yeah for some of the users Franco gives sods or screen salad issue - pixelated screen while other kernels work fine for them! Thankfully works fine for me

Well Franco works like a charm so far.. have been testing it for over 2 weeks and works very nicely ^^
Can't barely wait for V7.. Gotta wait for jkay's magic

[poll] what is the best kernel for the official ics ?

hey guys ,, i have finished all my work on viperx but im having difficulties for finding a suitable kernel to use without getting big battery drain ,,please select wisely ONLY according to battery life :angel:
I just tried Noobys kernel apart from stock one, I sometimes get excelent battery life, using almost 5hours of wifi, like 48 hours, but some days i cant get through the day, I think is related to my installed apps..
I wish i had tried more kernels to help you decide which one to use in your ROM, because im actually using Nemesis 2, but happens that i find both (rom+kernel) very stable for everyday use, and want to keep it like that.

IMO, The most important thing to chose a kernel is first it should stable, then good battery life. For include in your ROM I suggest you use the kernel that stable for everyone. As you know, every device has it own limitation, how high it can handle the clock, how low it can handle the voltage.
Why?
Some user dont know what custom kernel is, and what the advantages and disadvantages if using custom kernel. Some user usually flash and use the ROM as it is. If they flash the ROM and the ROM doesnt stable for them, mostlikely they will say something like "The ROM is not stable, I got SOD" or "This ROM is sucks, often reboot by itself". Yes, they will blame the ROM, whereas actually it because their device cant handle the UV or OC kernel.
Also you can write suggestion to use custom kernel to gain more battery life/performance in your ROM's thread.
The users can easily to flash other kernel that they like after they flash the ROM.
Well, this is just my thought. The decisions is up to you
----------------
as for the poll, I choose ZGK v0.1-beta, coz:
- 200/500/700/1000/1100 (OC not too high so it save, 200 as min clock good battery in deep sleep)
- stock voltage (no SOD)
- stable for my old P970, and battery drain is good enough

that is what im thinking of , but i need the best out of the kernel ,, hellmanor will help me out on this and with god's will i will release my rom next week probably :victory:
I was using Hellmanor's kernel for some days (Toccata 0.3) and the very was excellent!!! No problem with stability, always go in deep sleep.
Right now Im testing Adagio 0.1a hv

ROM & Kernels ?

I am newbie so please forgive me, Can some one please explain to me what a kernel is and why it matter?
Also say for example I install Werewolf CM10.1 ROM does the kernel also change to WerewolfJB automatically?
Sent from my LG-P880 CarbonRom
Yes because CM Roms run on different kernels and cant be used on stock or stock based kernels. And wise versa. And Kernels are...well not sure how to explain it. Let me try it. Is basically like a transmission. So better the transmission is so better runs and shifts the car. That's basically on a phone the same. Yes the processor is important but the kernel is what makes everything run like it should. I installed a costum kernel because the original one was so bad in battery life and this costum kernel is much better optimized. No more 10 or more % battery drain in standby in an hour. Battery life was pretty terrible on this phone now it is like a fully new phone with ok battery life.

The kernel is the core-engine all other software runs on. To make an analogy with a car:
The chassis of the car is the phone, the engine is the kernel and the body is the ROM. This is not a very accurate analogy, but I hope you get the point.
Different kernels focus on different keypoints. Some are very battery-friendly, some favor performance, some offer extra functionality to the system, etc..So there is not a one-size-fits-all perfect kernel.
ROM's are usually based on a certain structure, which the kernel has to support. So for a stock ROM you need a different kernel then for a CM ROM. Most ROM come complete with a kernel, a few don't. So if you flash a ROM which contains it's own kernel you overwrite the kernel that is on your phone. So let's say you've got the Optimus Prime kernel and then install the latest CM build, you overwrite your OP kernel and have to re-flash it after installing the ROM to get it back.In your case the Werewolf CM10.1 ROM comes complete with the Werewolf kernel.
Hope this answers your questions.

[Q] what is the best kernel for battery life?

What is the best kernel for battery life? William v5 or doomlord v12 or stock kernel

Doomlord kernel ruined battery life for me and I haven't tried william kernel.Stock kernel is best for me though.I get about 6 hours of screen time.
Although I think you should try them all for yourself and see which one works best for you.
EDIT:I have heard positive things about william kernel from my friends so I suggest you check that one out first.
Doomlord ruined my battery life also, so williams kernel V5 is little buggy about frequency management on 2nd core but it is really fast and save battery life !
i have great battery life on Doom12 and allthing is fine
There is no such thing as a BEST anything for all people
No one uses their phone the same, has the same apps/signal/setup/usage
Only you can find out what is BEST for YOU
The only thing you will get is a list of all kernels here as if you do the research you will see there are members in every kernel thread that think that one is the best.
BEST threads are closed on XDA because of this very reason
