I guess some of you know the pain I went through with Trickster MOD when some of my users came back to me crying that my MOD made their nav and status bars missing and to see the same thing here, it annoys me like hell.

The problem with these users is they themselves install modded SystemUI.apk with f***ed up signature, thus when dalvik-cache is cleared optimized dex file can't be recreated. This problem is because of shoddy skinner/modder and users should take it up to them to fix it, not stating FACTS where it isn't due.
[Samsung Galaxy Nexus] WitchMX:
I am on r215 and I see the same thing. It says 1400 in the App but in the widget it says 1200 all the time, no more and no less, only 1200.

I ran Quadrant Standard and in system information it said that the current frequency was 1200.

Why is kernel updater still listing the latest ICS nightly and not JB?
[Samsung Galaxy Nexus] bat0nas:
Thanks!!!
[Samsung Galaxy Nexus] windmark:
I just installed r216 and for fun tried to run 1920 MHz but my phone just froze and got really hot. It then rebooted and had drained 60% of the battery after.

Think I will stay on 1200, it works really well :)

Can anyone be helpful to those of us who simple don't have time to search 1000's of pages...

how are people getting near 4 hours screen on? WiFi off? Gps off? 3g only? Screen at lowest brightness? What is standard for those seeking good battery life?

Also, saw someone mention throttling when someone posted below 5000 on antutu. Is that thermal throttling? What antutu scores do others get on JB with Franco kernel.

And before you flip out.. yes I could search for the answers. But I just don't have the time. Besides, that's not the point of a discussion forum. The point is discussion...

Everyone's phone and they way they use it will yield different results. I never got over 3hrs on screen time. 2.5 is it for me and my usage, which is good seeing as though stock i could not get over 1 hours... so a 150% increase is awesome. You have to figure it out by trial and error.

Here is some food for thought. A Toyota Prius was raced around a track and a BMW M3 just had to stay on it's bumper. At the end of xxx amount of laps, the M3 got better gas mileage than the Prius. How you say? Because the Prius was running at 100% constantly and the M3 was was maybe at 20% of it's potential. The point of this is to show that even a low CPU frequency and battery oriented kernel can be bad depending on how you use it.

Also, don't say you could search for answers but "just don't have the time" and expect others to have the time to do your leg work, that's not what this forum is about. It just sounds rude.
[Samsung Galaxy Nexus] simms22:
yea, as many things not running as possible. if you dont use it, dont leave it on, itll drain battery. also, its a good idea to get rid of the facebook app, its written horribly and drains much battery even if never opened. lower your brightness, dont use autobrightness. live wallpapers drain battery too. and yea, that was thermal throttling. thermal throttle lowers your cpu speed to cool down the cpu, so benchmark scores can get lowered by a lot. and antutu score would depend on cpu speed.
[Samsung Galaxy Nexus] Wynnded:
Some might even suggest that if you have the time to flash custom ROMs and kernels, and post about not getting help in the discussion forums in addition to mentioning that you don't have the time to go back a few pages and read the thread prior to posting....then you just might have enough time to do so.

Any reports of data drops on r200? I've been having some since I flashed it.
[Samsung Galaxy Nexus] Moz007:
Franco, my sister has a galaxy s2 and when her phone freeze or crash, she can press the power buttom for a few seconds and the phone reboot, with my nexus i can't !

Do you think this is related to the kernel or the phone ?

I'm so tired to have to take off the shell and the battery...
[Samsung Galaxy Nexus] TyroneLT:
I concur with mostly what has been said here. You'll find your answers when you take the time to search. Not trying to be rude but your question greatly depends on how you use your device and what apps you have running on it. Now that being said, in short what has worked for me to allow me to reach 4 hours screen time is the follow:

Turn off radios when not in use (Wi-Fi, 3G/4G, Bluetooth, although lately I've been leaving Wi-Fi on and still able to get 4 hours screen time)

Turn screen brightness down (I range anywhere from 5% to 45% depending on the environment)

Stay away from auto-brightness (it uses up CPU)

Use an app like Watchdog Lite to monitor apps eating up CPU in the background and disable or delete them

OnDemand tends to be the most stable governor although with Jelly Bean its hard to say.

Outside of that you are going to have to do some reading, especially if you are using this Kernel.

[Samsung Galaxy Nexus] ray2jerry:
I can confirm random data drops on r216 (the same kind that were on the later ICS kernels but seem fewer) which is a shame, because I'm pretty sure I wasn't getting any with r215. It could also have been some cpu clock settings that I changed that caused it too, but it's hard to pin down exactly what could have caused it.

Also, the audio bug where it stops music playback if you put max volume is still sadly present (imagine my frustration between the audio abruptly randomly stopping and then the music disappearing completely when the data cuts out... I was only trying to listen to music after work! :eek: ). Needless to say I had to resort back to stock kernel to maintain my sanity and get my weekend rockin' lol.

But I'm sure he's on it, it's been amazing work so far... thanks Franco! :good:

[Samsung Galaxy Nexus] WitchMX:
My phone has been very smooth since #215, and with #216. I dont really judge the performance of my phone with benchmarks however I used to have a number as a reference.

The thing is that with 1400 OC I have higher results in Antutu than with 1500 or 1600, I found that weird, besides, when I switched to 1600, while runing Antutu a very thin green line flashed horizontally once in a while ...

Like I said the phone is very smooth and that is all that matters to me, but I just find that behavior strange, besides the widget is not giving me the right CPU Frecuency, I think.

Regards and thanks to Franco for the amazing work.
[Samsung Galaxy Nexus] dumbdroid:
After a full day with r216 i was out of battery by 16:00pm. And had several reboots when browsing with 3g connection at stock frequencies. The phone as getting real hot while browsing.
[Samsung Galaxy Nexus] WitchMX:
I usually get around 3 and 3 h 40 min of battery life, no matter what rom/kernel I use. With JB I 've noticed a slight improvement, I use my screen with around 80% to 100% brightness, because of work I am in a zone with very bad signal, it comes and goes so I guess that contributes to drain a little bit more juice.

In my experience with 1400 OC I get around 6300 in Antutu with Thermal throttle on, but with 1600 OC I get around 5700, so it is weird. Phone is very smooth and responsive so I dont really care for benchmarks.

Hope this helped

cheers

Interactive seems to be the smoothest running cpu governor for me.

Are the on demand and Wheatley governors taken from the previous franco ics kernels (that is, optimized) or default?
[Samsung Galaxy Nexus] dpaine88:
Been away from my PC for a week, just getting on JB now.

Are most of you still using 720mhz as a minimum speed?
[Samsung Galaxy Nexus] simms22:
try ondemand/deadline. then set the sampling rate to 30000(300000 is default) and up threshold at 98.
[Samsung Galaxy Nexus] lcheng1:
I think you mean the sampling rate to 30,000, and the up-threshold to 98.

[Samsung Galaxy Nexus] CaspaTheGhost:
The biggest factors concerning battery life are screen and radio, period.

More screen on means less battery, I don't agree with those who use low brightness settings as I have always used auto brightness without an issue.

Now radio, poor signal means less battery as the phone has to work harder to hold signal. WiFi is much more power efficient and will show major improvement in battery life when used. On mobile I can get say 3-4hrs max, WiFi gives me 4-5hrs.

Final tip is get an extended battery, official one that is, more power and improved ergonomics.

My experience has shown that all the rest (CPU, UV, sync etc) have a minimal effect in the overall scheme of things.

[Samsung Galaxy Nexus] M3drvr:
In other words, dont use the phone as a phone, or turn radio on. And put at a very low screen brightness.

Easiest way to get over 4 hours is buy an extended battery, the official saMsung one. That way you can use the phone normal and have it look gold with nice screen brightness and get in that 4+ area screentime

Deadline is the default here, I got tired of other IO schedulers that are not present in mainline kernel :)

[Samsung Galaxy Nexus] :
Hi,

With r216-512 GPU I can set 1.9 Ghz with the stock voltage, no freeze/reboot. About 35 mins of use at 350 Mhz-1.9 Ghz for a full use at 1.9 Ghz for about 6 mins (CPU time in System Tuner for me, but with a reboot... It's deleted so no screenshot) with browsing and SMS then freeze/reboot :(

I take a look at my last_kmsg and the reboot is caused by a kernel panic... ?

Maybe need some more tests by increasing the voltage slightly...

In any case not bad for a first test at this CPU freq :)

And 1.9 Ghz is not battery friendly, hey Francisco 1.9 Ghz brake my battery life, can you do something :what: :D ,obviously, just kidding :D

I'm glad to see my phone always handle 1.8 Ghz stable with your kernel (it will be time to bench at this CPU freq LOL). And handle a little 1.9 Ghz, I mean when I set 1.9 Ghz it's not a direct freeze/reboot... maybe a 1.9 Ghz stable playing with the voltage...

And with Jelly Belly rom all is fast, extremely responsive and smooth, it's awesome!
[Samsung Galaxy Nexus] kimboinatl:
Been running this for a bit today w/ a new JB ROM (Jelly Belly). No crazy overclocking, just running it at 1200/700 ondemand. Nice and smooth. I am using the 512 GPU kernel, though. I'm hoping I see some good battery life over the next few days.
[Samsung Galaxy Nexus] ramerco:
Thanks to people posting gov settings. Seems less laggy with on demand and 30000 sample rate. Also I can confirm better antutu score with 1400 MHz compared to 1600 or 1800... guess that thermal throttle really kicks in...

Glad to have found smooth and stable settings. 1400 oc, With 1250mv.

[Samsung Galaxy Nexus] mike216:
I'm going to post this again in hopes that some pick up on it.

I have this weird bug where my CPU stays stuck at max if I turn my screen on then enable data. I can fix this by simply turning the screen off then back on again. This happened on a couple ICS roms and now on JB. It has nothing to do with francos kernel. I'm posting here to help any with odd battery drain. Very strange so if you think this might be happening to you then grab system panel from the playstore and see how your CPU throttles when enabling data.

I'm a Verizon user you GSM guys probably won't have this bug,who knows though

Take care community

hi

Hello , i a a new here and i have 2 questions:

Since i have JB on my Galaxy Nexus what do i have to choose :

franco.Kernel-r207-384GPU.zip

franco.Kernel-r210-384GPU.zip

franco.Kernel-r215-384GPU.zip

franco.Kernel-r216-384GPU.zip

franco.Kernel-r216-512GPU.zip

And 2nd question can i flash this with Rom manager? THX
[Samsung Galaxy Nexus] mike216:
Go with 216-384 GPU and yes you can use rom manager but get use to not using it and learning to go in and manually flashing in recovery.

I hate to see new users using this buggy non source JB builds!

Be carefull bud and remember sometimes it takes a long time to boot so be patient
[Samsung Galaxy Nexus] ssglackey:
I had this issue too. Check your model number in Settings->About phone. It must be Galaxy Nexus, I had Jelly Belly and widget was displaying like yours.

Franco, quick report here on latest app 5.6.2:

If "Turn Thermal Throttle off" is checked and the phone is rebooted,

1) CPU settings

2) Color Multipliers

3) Contrast settings

will not set on boot after a reboot

but if the option is NOT checked before reboot, things work well :) thanks!

[Samsung Galaxy Nexus] ssglackey:
Franco,

Could you make an adjustable thermal throttle point? Now it is 75C, it would be nice to have a user adjustable range from say 65-95. Turning it completely off isn't so cool, because you can expect reboot, while with higher throttling point you can benefit from higher OC without a reboot.

Personally I can run 1,3GHz without throttling, but anything higher will cause my device to reach 75C quickly. With throttling point set at 93C (r210 linaro by rogersnm) I can run on 1,5GHz easily

I think your users will appreciate it.

Thank you
