Test of of 15.2 kernel turtle
[Samsung Galaxy Nexus] minipaolo:
I'm always following franco's suggestions to improve battery life.

This time I just wanted to try to set francoTurtle on 350-1000 and actually it seems to work much better than what I thought. It looks more battery efficient, even though I might be wrong because I just tested for 1 day. No lag at all and great battery life!
[Samsung Galaxy Nexus] chirea.mircea:
The problem is I don't have time to fiddle around with the phone, I need most of the apps. Though I'll look into the partial wakelocks, see if I find any culprits.

Man, wish I get that battery life :D

Off-topic: Why didn't I try AOKP sooner??!

That is with the extended battery, right? What brightness?
[Samsung Galaxy Nexus] modstorm:
Works fine for me
[Samsung Galaxy Nexus] nu_skool:
What an idiot I think I know what I am doing wrong... I'm running stock which is 4.0.2.
[Samsung Galaxy Nexus] laserprom:
No, standard stock batery whit 25% brightness and all time wifi
[Samsung Galaxy Nexus] Nebucatnetzer:
My idle drain with the test kernel is as well very nice.
[Samsung Galaxy Nexus] slimfady:
Try BetterBatteryStats to trace wakelocks :)
[Samsung Galaxy Nexus] Mondfahrer:
I am rly happy with my batter life. Can't understand all these issues. Since I am using smartphones, I'll always have to charge my phones every 1,5 days and I used quite a lot phones, Iphone 4 as well :-)

Still nice work Franco!

Hi ,

I've got a problem with this Kernel , every time i try to copy some stuff on my GNEX(Wifi or USB) the phone reboots and i get some kind of ext4 error in kmsg.

http://pastebin.com/f3e2igdq

Anyone got an idea whats wrong with my phone ?

edit:

Here is another example , this time i only copied some stuff after a reboot : http://pastebin.com/Y5xhEVQ3
[Samsung Galaxy Nexus] nikosrs4:
did you flash latest kernel? have you updated the franco.kernel app?
[Samsung Galaxy Nexus] darrendm:
Using the test kernel with dynamic hotplug. Will see how it goes over the next few days

EDIT:

What app gives accurate mA readings?
[Samsung Galaxy Nexus] nikosrs4:
try battery monitor.
[Samsung Galaxy Nexus] meilstone:
Can someone tell me me if playing music is below the cpu consuption to use both cpu's. Would be awesome if hearing music does also work with one cpu on the dynamic hotplug.

Francoturtle makes very good results. Having 28 hrs with 3 hrs display usage.
[Samsung Galaxy Nexus] Fihlvein:
Probably mentioned already although didn't see on last few pages: francoGazelle (at least) reverts to interactive after every reboot.

[Samsung Galaxy Nexus] franciscofranco:
Really? That's a new one. I'll check it out later.
[Samsung Galaxy Nexus] atsavlis:
Something new I noticed with the test kernel, not sure if anyone else is having it. When I open the dialer to either search for a contact, ir dial a number, it lags allot until the second core kicks in, then it runs smoothly...

Can anyone confirm this?
[Samsung Galaxy Nexus] CaspaTheGhost:
Gonna give test kernel a try, thanks for the continued work Franco.
[Samsung Galaxy Nexus] psycho2097:
it doesnt give accurate results. only gives accurate idle drain if left completely idle over 2 hrs. thats it.

playing music uses a low power C4 state or smtg, but it uses significantly low power than the 700mhz state. atleast thats wat i know.,
[Samsung Galaxy Nexus] rosswaa:
with Franco kernel ttorrent crashes and phone reboots constantly, other apps do it aswell

Changed to trinity and no crashes or reboots with apps
[Samsung Galaxy Nexus] opensourcefan:
I've been running Gazelle for a couple days with many reboots and it has stayed. When I selected it I confirmed if my script was written, which it was.

Did you check Set at boot?

---------- Post added at 09:47 AM ---------- Previous post was at 09:24 AM ----------

I just had an issue for the first time with this setup where the kernel app hung on start up for about 40 secs with only the header showing. Had to force close it to get out. Tried that 3 times, hung each time. Decided to leave it and it eventually fully opened after a minute or so. Then I hit the Check update button and it hung on that with it stuck blue for more than a minute. Is it a server issue maybe?
[Samsung Galaxy Nexus] Fihlvein:
Should be on boot but cannot confirm - kernel app doesn't start currently at all, hangs on start. Gotta put kids to sleep now, back later.

[Samsung Galaxy Nexus] solarus2011:
First, many thanks for the great Kernel and app Franco. I'm having the same issue. Worked great yesterday so hoping its just a server issue too.

[Samsung Galaxy Nexus] meilstone:
What do you expect from us to say?? You havent lost a single percent while staying in idle mode. Thats the best result you can get. Or should ur battery charge itself up??? :D
[Samsung Galaxy Nexus] trixnrice:
Could somebody provide some insight as to why i have ve so much kworker activity while in idle or deepsleep. took my phone off the charger before I slept last night. in 6-7 hours i'm getting 7-8% drain, which is not bad, but i've seen better. hot plug is enabled. and i'm getting a nice 2ma drain until wakelocks occur, log shows it bumping up anywhere from 9ma to 23ma and not dropping down for awhile, kworker specifically is showing high contribution to awake status. gmail and exchange wakelocks hardly contribute to the drain as their wakelocks last for only seconds, and show no percentage attributed to the awake time. so any ideas??? picture posted below using battery stats.
[Samsung Galaxy Nexus] poopooface:
I am using the test kernel as well and I am not having this issue. I have a fair amount of **** installed in my dialer (SIP account, google voice), but searching for contacts and dialing numbers is smooth as silk. I should note that I am running Turtle with the minimum set at 350, so as soon as one CPU kicks up to 700, it's engaging the second CPU. This could mean that my second CPU kicks in quicker than yours.

At any rate, I couldn't do a battery life test on the new test kernel last night because my gf kept on playing games on the phone after I went to sleep LOL. I'll try again tonight.
[Samsung Galaxy Nexus] Fihlvein:
About francoGazelle governor reverting to interactive - I wiped kernel app data and cache, uninstalled, reinstalled, verified that set on boot is ticked, and it reverted again after reboot to interactive.

Using 15.2, 700-1350MHz, using franco's boot animation. No hotplug.

EDIT: My bad, sorry. If both franco's kernel app and CM9's performance module have 'set on boot', CM9 will take over the command. ;-)

Check your System/etc/unit.d folder and see if the script was written, should say 13overclock or something like that.
[Samsung Galaxy Nexus] superbobup:
I've also been having this kworker issue, though it does not seem to affect battery life by much as I lose ~3% over 8hours. Franco answered what the kworker wakelock is but I have yet to figure out why they are there
[Samsung Galaxy Nexus] hasnol143:
what do you guys suggest for the best ROM for this kernel? I was thinking of trying out Apex
[Samsung Galaxy Nexus] franciscofranco:
People with app crashes please I need logs, the app works just fine for me.
[Samsung Galaxy Nexus] nic85:
Undervolting is the Way :D

Inviato dal mio Galaxy Nexus
[Samsung Galaxy Nexus] Fihlvein:
I can't come up with anything else than the following scenario: when the app is launched, it immediately tries to connect to some server address - and if it fails, it will just hang there as long as the connection is not succesful.

You could try to reproduce that by taking the server connection offline for a moment and try.

[Samsung Galaxy Nexus] opensourcefan:
It's working fine now, betting it was a server issue.
[Samsung Galaxy Nexus] Antzor:
Just here to report my battery life, so far very good for me. Screen on time was 2 hours and 43 minutes, using the interactive governor with 350mhz min and 1200mhz max speed.
[Samsung Galaxy Nexus] MarcLandis:
Why do you use the interactive governor when Francisco puts all the optimization into his own governors?

Marc
[Samsung Galaxy Nexus] maisi:
Yes I'm using the latest Kernel version.

I don't own the app, don't have a credit card :/
[Samsung Galaxy Nexus] franciscofranco:
Test3 kernel has been made available at: http://androtransfer.com/franciscofranco/index.php?dir=./Galaxy Nexus/test_kernel

It now checks for the current frequency (to see if it needs to shut down cpu1 or not) every 10 internal kernel ticks (HZ), instead of checking the current frequency every damn millisecond. This should decrease the overall overhead. Test and feedback please.
[Samsung Galaxy Nexus] DooMMeeR:
is it a problem of your Kernel or the current CM9 state that 5GHz WiFis are not showing up?

otherwise GREAT work franco :) brought your app, even if I don't really need it :) support is important ;)
[Samsung Galaxy Nexus] king23adrianc:
Decrease overall overhead. Does that mean losing performance.?!
[Samsung Galaxy Nexus] neoKushan:
Decreasing overhead is a GOOD thing.
[Samsung Galaxy Nexus] franciscofranco:
No.

"In computer science, overhead is generally considered any combination of excess or indirect computation time, memory, bandwidth, or other resources that are required to attain a particular goal. It is a special case of engineering overhead."
[Samsung Galaxy Nexus] arhung:
hi franco, can I use your kernel with ARHD 2.1.5?? because I love your kernel since i use nexus s but I also love using ARHD with my Galaxy nexus too! so if ARHD can use your kernel, I think it is perfect for me!!
[Samsung Galaxy Nexus] dmmarck:
Franco--

Thank you thank you thank you.

Gladly paid.

Take care!
[Samsung Galaxy Nexus] Kaboosey:
You can't since ARHD 2.1.5 is 4.0.2, whereas this kernel is 4.0.3.
[Samsung Galaxy Nexus] arhung:
ok:(then I just wait for mike release ARHD with 4.0.3
[Samsung Galaxy Nexus] zephiK:
Or... get a rom with 4.0.3 on it. 4.0.2 was so 2 months ago.
[Samsung Galaxy Nexus] Antob125:
Hotplug still has to be off?
[Samsung Galaxy Nexus] ballubas:
Yo! I've just downloaded the latest test kernel and will try and give feedback Sunday night!
[Samsung Galaxy Nexus] joelteixeira:
I want to know about hotplug too. Keeping off for now.

BTW, maybe placebo effect but the phone seems even smother than before.
[Samsung Galaxy Nexus] wareagle99:
He had stated previously to have the hotplug off I believe for the test builds.

It is working great for me at the moment. Previously I had flashed the first build but lost approximately 15% in 30 minutes for some reason. So I reverted back to 15.2 until now. This test is working great so far!
[Samsung Galaxy Nexus] DooMMeeR:
could anyone else have a look if they can see any 5GHz network…
[Samsung Galaxy Nexus] king23adrianc:
yes i can see it from wifi freq band. auto, 5ghz, 2.4ghz
[Samsung Galaxy Nexus] DooMMeeR:
Hmm so it must be an issue with CM9 atm -.- I can only see 2,4ghz networks atm and none of my 5ghz wifis -.- sucks as the channels 1-14 are crowded as hell here

But thx for checking:-)
[Samsung Galaxy Nexus] drawde40599:
700 min

700 min is recommended min frequency for any governor right? I'm using francogazelle atm 700/1350 is my setting ( when switching gov from francoturtle to gazelle app forced close btw it did set the setting but it did force close ) no I didn't get log sorry not *****ing just saying

Is there a place to whine about issues with the app?? Or kernel? Or is xda the place

App is force closes when changing the gov and freq (I did make sure no update in market )
[Samsung Galaxy Nexus] chirea.mircea:
Something is still causing me spurious wakes and I can't seem to find out. In middle there are some long wake portions I can't figure out who to blame for; I'm not talking about the single pixel one every hour or so (weather - through the damn app shouldn't update at night as I told it), I mean the three long bars.

BetterBatteryStats doesn't help much, as the first two are from when I was downloading something from the phone and playing a game and the rest are short couple-of-minutes long, mostly sync stuff but the wakes in the stats are over an hour long.

As for the kernel, I got pretty good battery usage during gaming as opposed to ARHD + tuna kernel UV. I use the turtle governor at 350/1200.
[Samsung Galaxy Nexus] johno168:
Hi, just a quick question whats the galaxy nexus default min CPU speed?
[Samsung Galaxy Nexus] aquavalanche:
oh my, you got a really nice battery usage there!

anyway, may I ask, what's the difference with Turtle and on demand..
[Samsung Galaxy Nexus] Ad1tya:
Hey Franco,

I can't seem to get USB OTG working. Is there some app I need?
[Samsung Galaxy Nexus] darrendm:

[Samsung Galaxy Nexus] Bisazz:

[Samsung Galaxy Nexus] zurchpet:
I am using fitsnuglys latest CM9 kang. And I can see and connect to my 5 GHz Wifi network.
[Samsung Galaxy Nexus] johno168:
Hi Franco! I just flashed your kernel and its really speedy on aokp, however I was wondering why your using 700/1000 on your francoturtle governer and not 350/1200. I changed it to 350/1200, but are there any advantages in doing so? Thank you so much!

EDIT: one more question :) has anyone been able to get 3+ hours on francegazelle? Thanks!
[Samsung Galaxy Nexus] stesmi:
What's wrong with the explanations given before?

700 vs 350: Tests have shown a negligable increase in power usage on 700 vs 350 BUT it is faster to drop down to deep sleep.

1200 vs 1000: 1000 needs less power than 1200.

Performance was good also so looking forward to the test...
[Samsung Galaxy Nexus] atsavlis:
With test version 3 I am having lags for a few seconds when I unlock the screen, then its all back to normal. I think the lag is until the second core kicks in?

[Samsung Galaxy Nexus] darrendm:
Been using test2 and most recently test3. Not had any SoD's.
[Samsung Galaxy Nexus] franciscofranco:
People with SoD's, are you GSM or CDMA? Are you undervolting? Because I haven't done any changes that can give SoD's, I only coded a timer that does nothing but checking if the HZ*10 is true or false.
[Samsung Galaxy Nexus] joelteixeira:
I'm using test 3 kernel since yesterday and didn't had any SoD yet. Using GSM and tried both Gazelle and Turtle gorvenors without hotplug.
[Samsung Galaxy Nexus] franciscofranco:
Dynamic hotplug is only with Turtle governor just in case you're wondering.
[Samsung Galaxy Nexus] drawde40599:
test 3

AT&T, GSM galaxy nexus --Only issue I had was with app trying to change from turtle to gazelle, app forced close phone got very sluggish I rebooted and got stuck at boot animation loop had pull battery, was strange,and never has happened to me be4 , but after that not one issue at all and app started working right kernel smooth running good no SoD, i normally run at 1350oc but left everything alone besides gov setting for this test kernel NO!! UV or OC
[Samsung Galaxy Nexus] CaspaTheGhost:
No SOD with test 3 but getting the lag at wake.

I'm GSM, no UV just running as you intended and the levels are higher than I have been running on previous kernels.
[Samsung Galaxy Nexus] franciscofranco:
Lag at wake...hum, that's strange. I'll drop a new test4 in a sec, imoseyon sent me a patch to fix the instability that comes from hotplugging. But I don't have any wake up lag at all. Did yo change anything else besides flashing the kernel?
[Samsung Galaxy Nexus] CaspaTheGhost:
Nope, just a kernel change today. Noticeable, and reproducible so I'll wait for 4 to drop. Apart from the SOD on 2, it ran well and seemed to have minimal idle drain.
[Samsung Galaxy Nexus] kecinzer:
Can someone help me investigate what causes my wakes? I'm desperate about battery drain in last days :(
[Samsung Galaxy Nexus] drawde40599:
No lag here, at all very smooth . did u not want gov setting changed? Keep at turtle? Or don't matter ( I like the gazelle 700/1200 )
[Samsung Galaxy Nexus] franciscofranco:
If your testing the test version the point is to test the dynamic hotplug, and that's only present in turtle governor.
[Samsung Galaxy Nexus] bimo2700mf:
the SOD already gone after switch the clock to 700-1000 MHz , if I switch to 350 - 1000 MHz the problem arise again, never happened with kernel test

I'm running GSM nexus with undervolt core
[Samsung Galaxy Nexus] jhericurls:
750mV for 350Mhz is way too low. Should be a minimum of 800mv

[Samsung Galaxy Nexus] flolep:
Hey guys.

I had two SODs too...

The first one was with test kernel version 1

The second one with version 3...

I am with turtle governor, from 350 mhz to 1350, no undervolt, just default kernel ones...

I have the GSM version of galaxy nexus.

The first SOD was with charger plugged.

The second SOD was with charger unplugged.

I have the checkbox of hotplug unchecked in francokernel updater.

I post here the screenshot of the battery stats history. You can see the stop with "missing data"... My phone was only sleeping and then stopped and I had to pull off the battery and put it back to have my phone working again... And battery usage has dramatically diminished when being in SOD state...

Hope it will help...
