Best Kernal for 10.1

Hi Guys,
What would ye recommend for the best kernal to put on with AOKP? Guess im looking for battery life rather than hugh performance, although i dont want it to be really laggy.

huh??? theres only one kernel that can used for AOKP and if you're using AOKP you're running it. you gotta do some reading up bro. AOKP is an ICS rom. but anyways. even if you weren't running AOKP there's only one kernel developer (pershoot) so far for the galaxy tab 10.1.

You always have the option of using a popcorn kernel. Not sure how that compares to the stock kernel or pershoot's kernel, but since it's really the only other option, I'd say give it a try. Best with melted butter.

I experienced really fast battery drain on pershoot's kernel. I don't have evidence to prove it and at the same time don't want to diss pershoot's work and there is a big chance that I might be wrong but that is what I witnessed.
that's why I stuck with stock based kernel's right now.

The popcorn kernel sucks until rooted and modded by heat.
sorry couldn't help myself like you couldn't.
As far as seriously, it all depends on how you configure and use Pershoots kernel as to if you'll experience lessened battery life enough to be bothered by it.
If you can read this it was sent using my GT-P7510.

ya man i know its an ICS rom but just flashed it for the galaxy nexus on friends phone and put a different kernal, was just wondering if there was different ones for the Tab. looking at the comments below it seems best to go with the kernal packaged with AOKP was just wondering if there was a better one. Thanks every one for your help.

kernel hero = Preshoot

At this very moment we only have preshoot's ICS kernel available for GT 10.1 since he is the only one involved in kernel development but we would all love to see more developers jumping into the Kernel Wagon!
But sincerely speaking ......... I think preshoot's kernel would give anyone good battery life if they do not have over-clocking on.

Pershoot's ICS kernel or HC?
I always had good battery life with Pershoot's kernel on HC. Actually, not just good - great.
However, so far, CM9 is a poor battery performer. I've got a suspicion why (I think it's the same wifi power management bug I experienced on the Galaxy S II with some firmwares) but I haven't had time to confirm.
If it's not the bug I'm thinking of, it'll be a ***** to debug - high drain despite good deep sleep percentages is really difficult to solve. (Basically, something is failing to power down in deep sleep.)
Maybe more info this weekend when I have time to get a kernel tree synced and building for the 10.1.
I think there were two reasons no other kernel developers have done much with the 10.1:
1) Until Heimdall supports the 10.1, developing kernels for it is a bit of a pain in the ass (Edit: If you have a retail Tab - the I/O Tabs had fastboot...)
2) Pershoot does a damn good job - if it ain't broke, don't fix it. There's only two features I miss that aren't present in the kernel, and they weren't worth the hassle of maintaining my own fork.

i get good with battery life on CM9 (for tab 10.1). especially so with the new wifi module coming.
this is with no sync on (using new module):
45 hours - 93%
with sync on, just a bit less then that.
another person with 3g + wifi always on (using new module), about 14 hours, lost 13%.

New module? Holy crap, I just revisted your sources. I guess ICS doesn't like the legacy BCM4330 module.
That explains a lot...
45 hours to 93% is consistent with what I got with HC. Right now, I'm intermittently (Sometimes life is great, but at some point it behaves like something is not properly powering down in deep sleep and remains that way until reboot - it can take 2-3 days to break in some cases, in others it breaks almost immediately.) getting around 1%/hour standby which is poor for a 7 AH battery on a wifi-only device (esp because I KNOW it used to do much better). I suspected it was wifi power management, but it's apparently not the specific issue I thought it was (even though it has very similar symptoms)... (As I said - I've been so busy I haven't had time to mess with it myself, I was going to this weekend but now it looks like I'll be changing track.)
I just rebuilt, time to flash!
BTW, which remote do you pull Dmitry Schmidt's patches from? Last time I tried to find upstream for that stuff I failed.

You sir, flat out ROCK!

So far, after repo syncing, rebuilding, and flashing last night - the new wifi driver seems to be doing the trick. I'm now seeing battery life consistent with what I used to see on HC. Went to bed at 95% and it's down to 94% now. Previously, I would've lost at least 10% in that period of time.
Of course, it needs a few days to shake out - previously it took as much as 2-3 days before it flaked out, although even pre-flakeout I don't think I ever saw CM9 on the Tab do this well in terms of standby battery.

I spoke too soon, and it turns out I was wrong with my initial guesses as to the nature of the problem. I haven't been as rigorous with the Tab as with my main devices.
It turns out it is exhibiting the same Broadcom bug with frequent wakeups that I777 UCKK6, I9100 XWKK5, and a few Infuse leaks had - See http://forum.xda-developers.com/showthread.php?t=1308030 , it's the first entry in the list there.
It's annoying because it's a combo of system and kernel - on I9100 and I777 it was usually caused by system changes, but sometimes would surface if a kernel developer started mucking around in the BCM4330 driver...
In the attached zip is:
A dmesg dump
A shot of the battery screen (less useful than I thought it was now that the problem is not what I originally thought it was)
A dump of /proc/wakelocks
A Wireshark pcap of the problem - note the protocol 0x886c packets happening at 1 Hz

Siyah vs. CM9 Remix | for Resurrection

Hey this is a thread for all the Resurrection lovers out there to discuss what Kernel goes best with Resurrection ROM
I've tried several Kernels by myself but couldn't come to a conclusion which is better in which aspects.
So lets discuss openly the pros and cons of each Kernel
If you have tried any other kernel other than CM9 and Siyah please put your opinions as well.​

Nice post! I'd be interested to see the results from ppl as I just updated to latest 1.7 remix and this time have left the CM9 kernal. I did think about flashing siyah straight after 1.7 package but decided to give CM9 a trial first
Will report in a few days!

I'm a Siyah fan too but after reading few reviews considered to give a try with CM9 will see how it goes

I'm currently using the stock CM9 with 1.7 and found it to feel pretty good so far, messed up a little yesterday when the phone froze while playing a video.
Before freezing the phone had 50% battery after removing the battery and restarting, the battery had dropped to 15%
I'm still a bit of a noob to all this so go easy
When flashing a new kernel, do I just put the zip on the card and flash?
Or do I need to wipe anything first?

This is my personal opinion, not trying to put anyone down.
Okay tried CM9 Remix kernel for few hours and already fedup :\
I see no better battery life compared to Siyah kernel, in fact CM9 Remix Kernel had lesser support than Siyah.
Lets see;
Siyah -
CWM touch recovery (and full support)
additional cpu governors (lulzactive,smartassV2,etc..)
Overclocking upto 1.6
support for BLN(Back light notifications)
CM9 Remix -
NO CWM touch recover and some of the CWM features are not available
NO additional CPU governors
NO overclocking
NO support for BLN
So for me CM9 Remix kernel isn't the one.
as i have tried Siyah kernel already im going to give Abyss or some other Kernel a try and will update on how it goes

This is a really difficult conversation because there are so many variables.
1) Kernels - each one has configurations so you need to mention what governor you are using and any other mods that you have done to the basic kernal config. Or if you are using it stock without changes you could state that.
2) Apps - all of us have different apps installed and some apps make demands on the system when it is supposed to be "sleeping". Dedicated battery enthusiasts use CPU Spy and Better Battery Stats to try to figure out what is eating the battery all the time. Then they freeze those apps until they are needed.
3) Usage - I'm retired, so I play with my phone a lot....spend an hour a day just reading XDA. I must turn it on at least 30 times between charges. Others have to work, so they put it in their pockets and leave it alone for a while. Some folks play 3D games which consume power like crazy. Using phone data eats more power than wifi. A black background on your screen eats less than a white background... and so on.
So this is not a simple conversation. The more you tell about your situation, the more others can see if it applies to them.
(PS - I´m not talking much about my setup because I'm still on RR 1.1 with Siyah 3.0.1+. I´m trying various governors to see which works best - currently on lutzactive. I'm usually down to around 45% at bedtime which is fine with me.....If I leave the phone alone and just use it as a phone, I can probably go 24 hours.

Siyah: Feature packed, lots of fluff, but very nice options as mentionned earlier.
CM9: Basic, VERY BASIC kernel. Gets the job done and most people sync their base with it.
I personally use CM9 with Siyah, works great.

I totally agree with you.
I use my phone very often too. not to play games but to text, listen to music, and i leave the phone data connected always to use IM services.
I'm sure it must be same with any regular user.
I love to play around with my phone as in trying out new stuff on it
This time its the Kernels and OSs that im testing on currently checking Abyss Kernel and already noticed that the soft key lights should be turned on time to time by going to settings :\
will see how well it does in other aspects

I've been using Siyah with RR 1.2 and 1.5 and battery life came upto 8-10hrs
wanted to try a different kernel and chose CM9 Remix which was in the download section of the RR thread and it was an utter disappointment for ME (others might like it)
refer to my earlier post for results.
currently im testing Abyss and will update on how it goes tonight

which one is the best?

It depends on user. Im a heavy user and a need freak so CM9 Remix didnt do much good to me trying Abyss at the moment. Await for results

This is very useful and im waiting for updates

AbyssICS (2.6b)
Okay lets see how Abyss worked out for me.
After the utter dissatisfaction over CM9 Remix kernel Abyss was quite impressive with battery consumption.
there's always a BUT
1. the softykey lights were never on even though i change settings, it stays on till the phone display sleeps and even of you turn the screen on again the lights never come back :\
2. Settings -> Storage always keeps force closing and you cant see the stuff in the external SD card even by using a file explorer (root explorer)
3. I didnt like the screen which comes saying some official italian bla bla when you restart the phone that got a very bad design
soooooooo im switching to Siyah-v3.2b4 after seeing its all new cool features and i found a great article on how to get the best out of the kernel
ill share it here : http://forum.xda-developers.com/showthread.php?t=1369817

No tweaks, but the screen on time suggests that the phone has been on standby most of the time, with no Data.
I always tend to have a fantastic battery performance too when I leave the phone on standby, with no Wifi or Data use.

I used the stock cm9 for a while on v1.7 RR and found the battery to last quite well, decided to try siyah 3.1.2 a couple of days ago and day by day it is getting better but not sure its as good as the cm9 yet....gonna stick with it for now and see as it has more options.

[Q] How to flash the Franco Kernel?

Hello,
I have done nothing to my Nexus 4 so far but I recently noticed that the battery isn't that good. I heard that the Franco Kernel might give more battery life. I don't play any games I just use it for texting, surfing and listening to music. Is the Franco Kernel good for my usage then or would you suggest another kernel?
I found the thread where I can download the Kernel but what is OP, Milestone and Nightlies? How do I flash this Kernel? Do I have to root? I couldn't find any HOW TOs.
Hope you guys can help!
Thanks!

Yes you will need to unlock your bootloader, install a custom recovery, and root. Then you download the franco kernel zip and flash it through recovery.
OP = original post
Nightly = means the latest build (they are compiled every night, and may have bugs)
Milestone = usually means a complete version (stable releases)

Milestone = stable version
Nightly = newer version may contain bugs
U first need to root your device and download the Franco kernel zip and place it in your extSdCard. Once rooted goto recovery (volume up + home + power) select install zip from external card. Browse to file select then install... And enjoy...
Make sure u know wot you doing. Read first n read alot before any action else you may brick your device.
:*: Neebi :*:

also you can buy the app and it install the flash by itself,
i guess you still need to root
since you don´t game it`s weird to have bad battery, try greenify

Your apps will make the biggest difference. Stop apps causing wake locks such as Facebook and anything with auto refreshing/push alerts.
The biggest benefit for me of using Franco is adjusting color profiles. Once you try other settings, you'll never go back to stock colors.

Kernels don't change this I'm afraid, and 3G will always use pretty much battery. Wifi on the other hand uses nearly nothing.
If you say you're not a heavy user then Franco's Kernel will be a good one for ya. As it contains hotplugging (meaning it will make the device slower if it's not used but fast when you want it to be)
Slower = more battery conservation.
Also let's you underclock your device. As for example you don't play games so you don't want it at 1512Mhz, you can run it at 1ghz and the time your screen is off lock it to 384Mhz (or a bit higher) which again makes your battery last longer.
It comes to a small downside, that kernel comes with its own app which costs a bit of money. But it's very much worth it as you can tweak it just as you want.

"unfortunatly" you need root before you can flash this. But there have been very useful links in previous posts, try those!
Then if you've done all that, look into Greenify. You'll notice a difference when using it, trust me

Hi easygoingx! i wouldnt recommend you flash franco for now. I have been using franco for 2 months , i purchased the app and everything but lately it's comsuming a lot of battery! it drained my battery a lot with last updates i was getting crazy!
if i were you i'll flash trinity!
i've turned on my phone 30 min ago and my battery is in 98%, with franco it would be by 92%
but if you wanna flash ,first root your phone and put a custom recovery (cwm or trwp) and download the zip to your nexus 4 and flash it from custom recovery.

That's definatly not the cause of Franco, but most propably some other apps rogueing. Try Greenify.

It's maybe the case with nightlies on particular devices.
I'm not the one to judge on that but on Milestones (Milestone 2 aka latest) there is nearly no battery consumption in idle and I've used Franco since r102 (newest is r136)
In the including pic I had flashed Milestone 2 from Franco, then afterwards changed some values in the app to my liking (aka max freq 1350, min freq 384 etc...) and then left it be for a couple hours and look at the result. Lost maybe 1% over nearly 4 hours. If I leave it on generally over night on wifi + data sync enabled, I lose about 2-3% (depending on the sync times ofc). I sleep approx 6h a night btw
Also feel free looking here and see all the positive comments of people and their battery! (also one of the most active and responsive forum topics around)
Therefore I highly recommend Franco!

Oh now I understand these terms. Thank you guys! I'm considering flashing my phone and change the color settings. I'm really annoyed by those washed out colors!
You know what really annoys me? That when I am on 3g and my screen is locked IT DRAINS my battery SO MUCH. Isn't there any ROM/Kernel that fixes that? I mean the S3 has this even on Stock and unrooted....
Hmm... Somehow my phone gets so warm lately.... I'm kinda worried.

They sure are.. but you can take a pick from like 30-35 presets (using Franco's preset myself). Trust me, the result is just... awesome! (if you prefer AMOLED (cause you refered to an S3, you can also change colors to that, it's in the spreadsheet here (check kernel column to see for your chosen kernel))

I doubt that there is a way around the battery drain with 2G/3G/3G+ but just having a different kernel will do miracles concerning battery life. Always feel free to ask this in the thread, maybe someone has a "solution" to your issue.
I don't know how often you're without wifi. But just make a tasker task like I have:
- "if wifi connected (=state)-> Data off"
- "if not wifi connected -> Data on"

Don't worry about it too much. The nexus 4 is known for having bad thermal handling inside the phone (read this) but it won't harm your phone in any way.
If however you are still worried just download the kernel and go to "Voltages", just press-25mV a couple times (I recommend 3 or 4x). This will reduce the heat generated from your device. (Yes your device can handle this, even more but I'm not responsible )
Another thing is what is getting hot inside your device, battery or CPU? Franco Kernel Updater (app) has Device Monitor which let's you check the CPU temps. If the CPU gets warm/hot too often or too fast, just reducing the max CPU frequency can help you out (1.5Ghz is "too" much anyway, you'll be fine with a couple steps less )
Hope this helped If you have more questions that I could answer, just quote me

[Q] [Kernel]Which one do you suggest?

Hi.
I'm looking for the best kernel for Nexus4 stock ROM 4.4.2.
I tested meny kernels and everyone have some problems.
One is freezing display, ather is draining battery or restart nexus.
I have no idea which one is the best form me.
I don't play games.
Usually I'm using Nexus to talk, WiFi, navigate and call by SIP client.
Stability and saving battery is very importent for me.
Temporary I returned to Franco Kernel r199.
It's work good but not the best.
Which one of all kernels do you suggest?

Try matrix. I am using that for a long time

From what you say: hellscore or matr1ix are the best for ya. :good: Test these 2 and go for the one that suits you the best.

Try moob amazing performance + good battery backup + ice cool phone while playing games ! All you need !?

HellsDoctor, guaranteed 4hrs+ SOT even with light gaming (Subway Surfer, Hill Climb Racing)

Please please best kernel threads are not allowed. Anyways I suggest moob or Mirage kernel

Hellscore and HellsDoctors were OK but now battery is down after 6-7 hours.
I don't know why.
On Franco kernel r199 I can use My nexus even to 20h.
Today I was upgraded My navigate app (1,8GB) by WiFi and now I have 60% battery and 11h using Nexus.
WiFi and 3G is always ON.
GPS is On when necessary.
I'll try matrix and moob.

Best kernel threads are not allowed. As you can see, you have several posts with as many different answers, leaving you with the exact option had you not even created this thread: go read the kernel threads and search and try them for yourself.

Best kernel solution?

Hey guys! This is my first topic on XDA, so I apologize in advance if I do something wrong.
I love my 6P and since it's a Nexus, there's always some tinkering so I can make it even better and suitable for my needs. I pretty much like stock-ish ROMs with that touch of Pixel phones and I find that original Google kernel serves me well in terms of battery life and overall performance (I'm probably one of the rare dudes to state something like this). But original kernel is very limited in terms of other options custom kernels offer, like gestures, screen color control, audio boost, etc. Regarding custom kernels, I never had any good experience with battery life, even when setting the governors on powersave/noop/cfq or any other I tried.
So, I guess what I'm asking is - can you recommend me a kernel that's exactly like the Google's out-of-the-box, but with those added options I mentioned above? Or is there some way to restore settings on custom kernels to default Google's settings?
Cheers!

I keep falling back on ElementalX, it offers enough customization, and still has decent battery depending on your settings. There's a million and 1 ways to configure it. I tried other very popular, more feature rich (they have everything, plus the kitchen sink, and sometimes cupboards too), but the battery drain is just too high for my liking. Not even using the phone, and every time I wake it with one of those kernels, it's dropped another 8-10%, without being used.
I haven't tried them all though. Many of the slimmer kernels don't offer a way to disable touchboost, so I rule those out as soon as I see that.

Oh, ElementalX was my first choice too, but suddenly that too started to drain my battery quickly after a while. At first I thought it happened because of some app, but when I flashed default kernel everything got back to normal. That's why I wonder is there a way to copy those default settings and apply them to some custom kernel.
You think disabling touchboost is a big deal? Cause of battery life or something else?

You may check this thread regarding kernel governor profile customisation:
https://forum.xda-developers.com/ne...dvanced-interactive-governor-t3290605/page471
A lot of options to choose from. EX Kernel, Flash Kernel, (I guess other kernels) support this mod using a kernel manager app.
I'm currently using EX Kernel + EX Kernel Manager + Ghost Pepper profile.
Fast enough for me. Plus it helped me saving some juice.
Depending on your usage, it takes trials and errors until you find the good kernel/config that suits your needs.
Happy reading...

Wow, I stumbled upon some other loooooong post about governors, but this one is amazing! I didn't know touchboost has that much influence on battery. I will try this out, thanks mate!

I get better battery life on ElementalEx over stock kernel without a doubt. I am running interactive with Ghost Pepper profile and touch boost disabled. If battery life is your main consideration you could try Franco's Kernel but you are sacrificing some phone performance to get the better battery life. I found the drop off in performance very noticeable but his kernel has its fans. I think ElementalEx has a better balance between performance and battery life.

Touchboost wastes battery because it boosts you to 1248000 every single time you touch the screen, and it holds it for like a second or two. It does make your phone faster, and responsive though.
