So 6.3.1 is better than 6.2?
[Samsung Galaxy Nexus] slider112:
I don't know about better necessarily, but I've been running 6.3.1 for almost a day now and it definitely seems to be on par with 6.2, which is pretty amazing in it's own right. :D
[Samsung Galaxy Nexus] sola fide:
I'd say that 6.3.1 has some advantages over 6.2 If you use the interactivex governor. When you look at the change log, imoseyon notes several bug fixes and improvements to the interactivex governor as well as the general interactive governor. While I haven't noticed a huge difference between the two in my daily usage - I will say that Bug Fixes are always a good thing. :good:

I've had my phone on me since 8 this morning, basically 12 hours right now. My screen on time is around 2 hours and played ingress for 30 minutes of that. Only charged it for 5 minutes while in the car moving it in the parking lot...right now I'm only at 58% battery life. That's incredible no matter how you look at it. (not even accounting for all the random apps I have syncing in the background and the constant WiFi on and off as I move around). There's a reason I've stuck with this kernel and don't stray away from it: stability, dedication, and consistency from imoseyon. :D
[Samsung Galaxy Nexus] pcphobic:
I haven't had the chance yet to do an overnight battery drain test yet.

But based on usage I can definitely see some improvements in terms of screen usage time with version 6.3.1 stable.

I'm still experiencing this with 6.3.1 and AOKP build 6.

Fast Charge is off. I have tried on 3 different computers (all have been updated to the latest version of adb from the Android SDK), all show my device as offline.

This is not an issue with franco kernel or AK kernel, both allow access via adb (my device is not shown as offline).

Has anyone found a solution?
[Samsung Galaxy Nexus] Blackcrx:
personally I feel that governor settings are different for everyone and depends on how you use your phone.

best thing is to understand what the settings do and adjust them to your needs
[Samsung Galaxy Nexus] dirtygoldfish:
I had this happen, and it had to do with 4.2.2 and some changes in debugging I believe. You have to update SDK tools through the Android SDK Manager, and then when you plug your phone in a prompt comes up. After that you can ADB as normal again.

Is it Windows 7 32bit or 64bit, I've found this can be a difference that causes problems. On Windows 7 does the phone even show in your device manager? If so, what does it label it as?

Well what governor and i/o scheduler are you using? That can make a difference. Are you using an app to control it with profiles? Or just using 1 set of settings for all uses?

---------- Post added at 01:09 AM ---------- Previous post was at 01:05 AM ----------

Also, you might want to know that the creator of this Kernel is not on this forum. imoseyon hosts his kernel on Rootzwiki. The OP gained permission to repost it here on XDA but the OP has no control over advancements or bug-fixes. If something really is wrong with the kernel it will probably be best to post it on his Rootzwiki thread. We can really only give you advice and tips for this Kernel on XDA. But, I would wager a guess that some setting changes would clean up the problem you're having.
[Samsung Galaxy Nexus] vivekbalan:
Thanks for the reply. I will try to post the query in rootzwiki then.

I used stock LK settings, did not change any governor or any other Kernel settings. Tried restarting but no use.

Can you tell me the best settings to run the game smoothly. Thanks again.

Does this kernel really support SWAP? And can I use SWAPit Expander with it?
[Samsung Galaxy Nexus] wasdf:
If you are hunting for performance, you should use franco one, try to run nenamark2 with lean and franco and u will get what i mean :p

Edit:

I think u may want to test different gpu mhz, and I have tested it already...

512 27.0 | 26.6 (buggy and lag screen.. so i just test it for 2 times only..)

384 27.5 | 27.6 | 27.7 | 27.6 | 27.7

307 24.3 | 24.4 | 24.2 | 24.2 | 24.3

Now go for franco kernel and run nenamark2 and see the different! I guess you must love lit :P

outstanding idle draining with this kernel. tested 6.3.1 over night for 8-9 hours, started the test with 76% battery, woke up with 76% (!!!!) with 3g on. amazing.

ok i may exaggerated, it was more like 7-8, still amazing.
[Samsung Galaxy Nexus] oifi:
Update sdk
[Samsung Galaxy Nexus] sola fide:
ADB works fine for me. However, you do need to update the SDK with 4.2.2. The first time you attach your phone with debugging enabled your phone will have a screen asking for permission to use the computer you're connected too. If I remember correctly there is a "always trust this computer" checkbox. After that you shouldn't have any problems.

---------- Post added at 10:38 AM ---------- Previous post was at 10:31 AM ----------

I personally use the interactivex governor with ROW scheduler. Always been very smooth and quick. There are ways you can adjust all of these settings using scripts. However the easiest is to use an app like SetCPU or TricksterMod. I prefer SetCPU to create profiles for different scenarios (charging w/ screen on, screen on, battery below 25%, on phone call, etc). If you use interactivex do not set a screen off profile. This is mentioned hundreds of times on this thread and on the rootzwiki thread.

The interactive governor is also another very popular choice as it was created by Google. Also, some people prefer deadline as the I/O scheduler. Hope this helps with you're using of LK.

However, if you really want more performance maybe another kernel will suit you better. There are other kernels that focus more heavily on performance. LeanKernel is designed to be lightweight, efficient, snappy and smooth when the user needs it, but also battery conscience at the same time.

---------- Post added at 10:45 AM ---------- Previous post was at 10:38 AM ----------

Also a good option, I also modified my GPU freq to 384 and found a slight improvement but without any major battery loss. I also agree that pushing it to 512 is overkill and will probably cause problems. Leankernel by stock install will run the GPU at the phone's stock 307mhz. On rootzwiki there is a post under FAQ's that has very easy instructions on how to run a script with terminal emulator to bump you're GPU up to 384.

Franco kernel is also a well known stable and well developed kernel for the Galaxy Nexus. I've also used Faux's kernel and found it to be a good one as well. Some users really like the DerTrinity Kernel but I've never used it.

i think its gotta do with the ak kernel. i flashed it for testing, then saw there is a new version of lean, flashed but it aint booting anymore. checked the ak thread, there was a zip which supposed to revert the wifi thingy and says should work but it didnt, tried old 4.3 lean and it doesnt boot either.

just flashed franco kernel and it booted ok. weird..
[Samsung Galaxy Nexus] nickcct:
From AK kernel, you should flash the reset stock kernel before u flash to other kernel.

I experience that even I can boot, but feel lag when from AK kernel flash back to lean kernel. After flash reset stock kernel and old wifi driver, I feel smooth and no more lag on lean Kernel.
[Samsung Galaxy Nexus] moomingstarz:
I think you're right. I'm *pretty* sure a few dozen pages back, someone did say something about coming from AK gave bootloops and they had to flash something else before going back, and I assume that is the revert-wifi thing. The only way I know how is to go back to full stock and then re-flashing your rom + lean again (if you really wanted to use it) but the process is tedious and not worth it :eek::eek:
[Samsung Galaxy Nexus] drmxmyt:
flashed the stock kernel zip, then revert the old wifi. but still lean kernel doesnt work. good thing i did a nandroid backup yesterday. i can go back and try. but its silly a small thing makes so much trouble.. :(

Is this because of some settings in the kernel that the sound on my calls is getting all messed up? I have never had this issue with the stock kernel before. I'm on ARHD with Lean kernel (latest) and using Trickster Mod app for control. Amazing work by the devs of both!

Hey guys, I hope someone can help me here.

It used to work, but for some reason lately I cannot run the checkv script, or any other scripts. I checked the Terminal and Verify PATH entries is not on:

but after I try running checkv I get:

SU rights are given properly.

I am on Samsung Galaxy Nexus GSM running latest AOKP. This has been happening to me on the past few 6.x LeanKernel releases, I am currently on 6.4.

---------- Post added at 12:53 PM ---------- Previous post was at 12:40 PM ----------

I found a solution. The script files were not in /sbin. LeanKernel is integrated to my ROM (AOKP) and it didn't have the scripts there. When I re-flash the kernel with Franco's app, it doesn't put them there. So I just flashed the zip from recovery and that worked.

Wow, this kernel is very very fast but my battery drains very quickly, and I have the same configuration as I had in Ak kernel. Is interactiveX the same as ondemandX (switch off one core processor when on deep sleep) because if so, it should have lasted more than in Ak with interactive...
[Samsung Galaxy Nexus] Braneless:
I've found the opposite to be true. Per Battery Monitor Widget, my phone drains at an average of 15%/hr (while screen is on) with JBS 5.1 and 6.4 Drain rate averaged almost 30%/hr with same rom and 6.2

I run 350/1350, 384, and interactivex. Getting about 15hrs of life with 4-5hrs of screen time.
[Samsung Galaxy Nexus] dirtygoldfish:
Regardless of if I'm running interactive or interactiveX my standby drain is about 1%/hr with wifi or data on, and a bit less than 1%/hr if those are both off. That seems pretty normal based on what people have reported over at the Rootz thread. So if yours is draining substantially higher, as always, check if anything is keeping your phone from deep sleeping.
[Samsung Galaxy Nexus] pcphobic:
Guys, I have done my own testing and I still find Lean Kernel to have the least battery drain during idle. I do my idle drain test when I sleep so that I do not disturb the test. Always...the result shows Lean Kernel drain the least battery when the phone is idle.

For those having mysterious drain, it could be some rogue app or you have turned on Google Now or you have accidentally enabled "Always Report My Location" in Google Maps Location Settings.

I suggest u install Wakelock Detector and see what is waking up your phone most often when it is idle.

For those interested to know, with Lean Kernel I can leave my phone on 3G (not using wifi) and it drains at the rate of 1% per hour. That is pretty good.
[Samsung Galaxy Nexus] binlalo:
I'll check the wakelocks because it's weird, leankernel has always given me the longest battery life so there must be something wrong here.
