Just a quick heads up here. I've been using and updating your kernel with your app for while! Thanks for your hard work!

This morning I realize that the App now flash the Kernel at the same time. After a while it was downloading I got an error from Android telling me that the Franco Kernel Updater isnt responding. So I choose WAIT so it can finish download... the program finally restart my phone and flash the Kernel.

But Afterward, I got Several app that the Internet wasn't working anymore. (Tiny Tower, Swift Key, DragonCraft... ) And other app were OK (Like the Stock Browser or Transdroid)

I flash Back version 15, and everything is OK. Anyone else having this issue or this might be only a Bad Download...

I'm running AOKP Btw.

Thanks.

Jon.

I am totally for it, one of the main drains for me that I want to drop is the drain when in standby mode. On my previous phone (HD2) that was running exactly the same setup I have on my nexus as far as apps go, the drain would drop down to 3-6mA in standby mode, compared to the 40-80mA drain in the Nexus. The HD2 was a single core clocked to 1,2...
[Samsung Galaxy Nexus] franciscofranco:
I'd say you should go to the recovery and flash the .zip file inside /sdcard/Download, that should do it.
[Samsung Galaxy Nexus] jhericurls:
I agree. Screen off usage is already excellent. This could a good solution to help reduce battery with screen on.

The problem I see is that it might be difficult to set were the threshold should be before it jumps to dual-cores. Set it too low and it will be using both cores most of the time. Setting it too high and it would impact performance, and would there be any lag on crossover...

Hi! Im not really sure how the cpu sets its speeds....I used SetCPU to set a profile so that when the screen is off the cpu speed is forced to 350MHz. Now from what I understand when the phone's screen is off and not being used it goes to deep sleep. Does the profile I set interfere with this? Using CPU Spy its 46% on 350 mhz and 28% on Deep Sleep (While having normal CPU set to 700-1000 on Turtle Governor). Will it be better to disable the profile?

Thanks
[Samsung Galaxy Nexus] bradm23:
Franco, I really like this idea. Its your kernel so go nuts with the dev! I love the non widget idea, with maybe a app feature that you can turn on and off like hot plug!
[Samsung Galaxy Nexus] franciscofranco:
Don't use profiles.
[Samsung Galaxy Nexus] modstorm:
Thanks for the advice :)
[Samsung Galaxy Nexus] Nebucatnetzer:
This sounds really interesting.

However it might be a good idea to release this as a second line. Because it could cause many problems at the beginning. Nevertheless would it be very interesting if we could test it as well after your inner circle tried it. Just an idea.
[Samsung Galaxy Nexus] nikosrs4:
have you tried anything stressful after the uv? like watching an HD youtube video over 3G or something.
[Samsung Galaxy Nexus] franciscofranco:
Yes, today I'm gonna experiment with it and will probably release it, if successful, as a test version, can't make it as a mainline download or my mail inbox would drown from an email overflow :D

[Samsung Galaxy Nexus] darrendm:
13h+ and just 50%. Light usage, yes - but all prior kernels was well below this % with equal usage.

Best kernel yet Franco!
[Samsung Galaxy Nexus] :
I like the idea as well - being able to maximize battery life with the screen on would be great.

Also just to help balance out some of the battery drain feedback - I've been running 15.2 since last night on turtle with no performance issues, very snappy performance and am down to 60% at 16h 34min with WiFi, 3g, sync on and just over an 1h 10 min of screen on time (AOKP MS3).

It's not the most constructive to help improve a new kernel release but hopefully it serves as some motivation to keep on going - it's incredible work.
[Samsung Galaxy Nexus] ChosSimbaOne:
This sounds like a great idea, I could surely 1+ this. Thinking that maybe the threshold issues, could be customizable through the app do that PPL could find there level, instead of you receiving hate mail. Just an idea :-)
[Samsung Galaxy Nexus] EddieN:
I hate to be saying this since I didn't have issues before, but right after a FULL wipe, with ONLY CPU Spy and BBS installed, my phone has a really hard time falling asleep. It keeps lingering at 700Mhz and I don't know why. None of the times in BBS add up to the time the phone is at 700Mhz, so I can't see what's keeping the phone at that frequency.

The phone seems to fall asleep easier when I turn wifi off with the screen off, but shouldn't the phone sleep even if wifi is on when the screen is off? Maybe I misunderstood something.

Running #15.2 on AOKP M3, totally wiped with only BBS and CPU Spy installed

I think I'm having sleep issues too. My device has been on for about 5 hours and in CPU spy, it was showing over 3hrs in 700Mhx and only 1hr 30 mins in deep sleep.

So I reset CPU spy just now and left it for about 10 mins.

32secs 1000MHz and 12 mins @ 700MHz, no deep sleep.

Also running AOKP M3.
[Samsung Galaxy Nexus] neoKushan:
Ok, so maybe someone can explain this.

http://i39.tinypic.com/23tgwo8.png

This is a pic I've just taken. I left work with a full battery, got on the train and went home. Now, I'm not complaining about battery life or anything, but you'll notice that my graph has two distinct inclines (Right when the GPS enables)? One is clearly when I get home, as it coincides with the Wifi connecting but here's the thing - I didn't plug my phone in to charge, or connect it to anything. So how on earth is is actually going up?

I know the Kernel is wonderful and all, but self-sustaining? Say it ain't so! =P

After installing 15.2 I lost my sd card. I had to revert back to 13.1 and it works now. Went back to 15.2 lost the sd card again.

The kernel I run on my Optimus 2X does exactly that. He has what he calls normal (performance) and batterysaver modes.

I don't know why but he actually looks at how long the phone hits a certain speed (MHz) instead of system load. I'm sure there's a reason for it.

Numbers in (parenthesis) are batterysaver kernel, other is performance.

If the speed of the phone exceeds 650MHz for 200ms (300ms), he enables the second core. If the phone goes below 500MHz (650MHz) for 1500ms (1000ms) he disables the second core.

I get awesome battery life now from the phone, which I didn't when it was new.

[Samsung Galaxy Nexus] AdamHart612:
I'm also seeing a similar problem. CPU Spy shows just 9 minutes of deep sleep over 4 hours, losing 70% battery in that time with less than an hour screen on. Better battery shows that it's *backup* (com.google.android.backup) causing a partial wakelock. Came from a full wipe.

All the other versions I've flashed have been awesome though! Over a day battery and fast as hell. Thanks Franco!
[Samsung Galaxy Nexus] goldleader:
Flash 15.2 from recovery and you're good to go ;)
[Samsung Galaxy Nexus] EddieN:
Could you post a pic of you seeing that wakelock in BBS? I'm seriously not getting any information about whats keeping my phone awake. It's all just kernel uworker stuff and everything is under 10 seconds. Just doesn't add up. I even set a custom reference but it gives me similar information.
[Samsung Galaxy Nexus] ArmanUV:
15.2 on AOKP M3 rock for me deepsleep-wise:
[Samsung Galaxy Nexus] EddieN:
Feels like I should be getting the same results considering i'm on a fully wiped phone with the same rom and kernel, NO other apps that are conflicting. Unless of course there's a major difference in hardware in all phones which I doubt
[Samsung Galaxy Nexus] jhericurls:
False alarm folks, deep sleep working fine. I realised that if you have your phone connected to a USB, it doesn't sleep... you learn something new everyday

Settings > Back up my data - untick. Problem solved
[Samsung Galaxy Nexus] AdamHart612:
Sure.
[Samsung Galaxy Nexus] bradm23:
I'm assuming you updated your kernel lately? This is what happens when the phone re calibrates the battery (one of the reasons clearing bat stats do not work)

This will go away after you let your kernel settle in. I once ran my phone to 1%, put it down thinking it was going to die soon, picked it up an hour later and saw 10% remaining.

On a side note, this is a prime example why it bugs me when a new release is to come out and people are complaining about battery life. It truly takes 2-3 days and a few charge cycles to settle in. So when people complain how bad 15.2 is, most likely user error (rogue apps) or simply the battery is lying to you.

15.2 has been running 12 hours for me and I still have 70% remaining! I have been using it a little, with some web browsing, texts and calls. I can't wait to see what this new idea Franco is taking about brings. I would love a performance kernel that shut down a core under low use, seems like the concept of a hybrid car
[Samsung Galaxy Nexus] AdamHart612:
Those are the results I typically get as well. Gonna try jhericurls suggestion, then wipe and reflash if it doesn't help. I actually did a double take when I saw how much I'd lost after a 20 minute drive. Normally on Franco Kernel I'll lose 1-2% an hour max on standby, but on the drive alone I lost like 15%. And the phone was charged while turned off. Lol, I'm pretty sure my battery called in sick today.
[Samsung Galaxy Nexus] neoKushan:
Ahh thanks for that! To be fair, I've only had the phone a couple of days, so it'd probably still be calibrating the stock ROM at this point, nevermind the custom ones.

As for this shutting down a core idea, I'm actually surprised it doesn't do that itself. nVidia made a big deal about how Tegra 3 had a 5th core which gets used when in low power mode, shutting down the other 4 cores - makes sense for a dual core system to do the same, for the same reasons.
[Samsung Galaxy Nexus] darrendm:
Looking good
[Samsung Galaxy Nexus] stesmi:
Do you know why it has a 5th core?

There are two explanations. The real one and the one they tell us.

The one they tell us is that the 5th core draws less power than the other 4 cores so they added that to switch to.

The real reason is that the 4 cores cannot be switched of individually, neither 1 and 1 or in pairs or anything, it's either all 4 on or all 4 off.

The 5th core actually draws MORE power than the Quad with 3 cores disabled. (I have read a deep test where they disabled 3 of the cores and measured power draw.).

I know, silly but that's how they designed it.

And of course, the 5th core draws less then the full quad enabled, but that's besides the point - adding extra logic (ie the fifth core) will draw more power than not adding it to begin with, not to mention extra cost of producing it, etc, etc.

Sorry for the OT, I will now resume my regular topics.

[Samsung Galaxy Nexus] turl1:
That's the same concept behind hotplug governor, why reinvent the wheel? :rolleyes:
[Samsung Galaxy Nexus] StuMcBill:
I would also be interested in a version where CPU1 shuts off when there is less load on the CPU with the screen on!

Perhaps even a toggle switch, so when you really need to save battery you can disable the second core altogether?

Keep up the good work! :D
[Samsung Galaxy Nexus] bradm23:

I noticed in your app that after I updated it hot plug was unchecked. I did re apply it but just wanted to see if this was normal. It was checked before update.

Hotplug governor is broken at the moment, I'll do it in my own way, and wheres the fun if not trying it? ;)

So far it's a success, my device is shutting down cpu1 during screen_on if the frequency is 700mhz. cpu1 is online again if freq its > 700mhz. Let the testing begin. Currently only for turtle governor.

I've had this issue since I started using the Powersaver mode of the AOKP ROM (i.e. turning off wifi when phone goes to sleep). When the phone wakes up again, the wifi come on with full functionality but shows zero signal even when connected).

Can someone who uses AOKP Powersaver mode with another kernel please confirm if they get this issue? Or otherwise confirm if it is a kernel or a ROM issue.

Re: wifi signal meters.

I just toggled wifi and seems to work now. Hmmm very odd.

[Samsung Galaxy Nexus] samizad:
In AOKP, would you mind activating the powersaver and tell the screen off for a while? Then see if you can reproduce the wifi meter bug.

I can confirm that if you deactivate the powersaver mode, and toggle the wifi on and off, then the bug disappears.

[Samsung Galaxy Nexus] Antob125:
Can anyone recommend setting for franco kernel? I just downloaded his app and have it set to francoturtle and hotplug enabled. I'm looking for the best setting for battery without hindering performance too much.
[Samsung Galaxy Nexus] samizad:
I think the app default settings: francoturtle, Max CPU 1000 Mhz are the best, with hotplug enabled.

It gives very good performance for day to day stuff, and you can always switch to higher CPU or governors on an as-need basis.

These settings, with AOKP Powersaver options, give me about 1% battery drain in 6 hours, when my phone and I are asleep!!!
[Samsung Galaxy Nexus] Antob125:
Do you recommend undervolting? Is so does anyone have good values that are stable and don't hinder performance too much but improve battery?
[Samsung Galaxy Nexus] samizad:
I don't recommend undervolting below the default levels. In fact, my phone rebooted this morning when the alarm went off and I touched to dismiss it. I think the problem is the cold windowsill where I put my phone overnight. I will experiment tonight with slightly higher voltages than default.
[Samsung Galaxy Nexus] ChosSimbaOne:

[Samsung Galaxy Nexus] kecinzer:
I have to say, that version 15.2 is the most battery drain I ever try :(. I don't know why.

I have AOKP M3 - clean install, only I stay with stock kernel for about 15 hours and I had almost no drain, then I flashed franco 15.2 and now battery goes down in 8 hours over night (no data) 6% (normaly I have 2-3%) and also during day with data on and idle.

I have XXKK6 radio.

First. Thanks Francisco for this wonderful kernel.

I only tested it since 15.0 but it really seems perfect performance wise and seems bugfree too.

But I have to say that I remarked the battery drain too with 15.2... 15.0 and 15.1 were better battery wise.

Take care and keep up the good work :-)

Had a strange battery thing happen this morning...

Phone was plugged in and charging from around 10pm on, at 3am or so battery monitor showed that it reached 100%, it stayed plugged in but fell to 99 and 98 quickly and then stayed at 98 for another 5 or so hours without a change in voltage. I removed and re-connected the plug and it started charging again.

Seems as though once 100% was reached it stopped charging and didn't start again until I interfered.

Not sure if it's a ROM thing or what, first night with this setup.

[Samsung Galaxy Nexus] franciscofranco:
Ok so let's do a bit of testing:

http://androtransfer.com/franciscofranco/Galaxy Nexus/test_kernel/

That test kernel has the dynamic hotplug coded into francoTurtle governor, which means that everytime that the device is at the minimum frequency cpu1 is down. When it's > min frequency cpu1 is up again. Since with turtle governor the device spends around 90% of the time at minimum frequency its going to be interesting to see if shuting down cpu1 will be beneficial or not.

The only intruction is that you have to disable hotplug mod to prevent conflicts.

---------- Post added at 02:45 PM ---------- Previous post was at 01:59 PM ----------

tested quickly for 20 mins:

it appears that while screen on, the frequencies change a lot more than usual, i mean, i am using system tuner, and the load keeps haphazardly increasing and decreasing. i hav been idle, screen turned on for around 19 mins, and i have 7 min @700 and 12 min @1000. cpu1 keeps coming online intermittently every 2-3 secs even if i am idle, just system tuner open. this never happened on turtle. at turtle in idle i used to get 90% @700.
