Now, that's too fast a consumption of the battery. Depends what you are doing of course (lte connection, video, low signal, navigation, etc) but it should last you between 3 & 4 minutes I'd say.
[Samsung Galaxy Nexus] jhericurls:
I just did a quick test.

Nightly #10 with TeamKangs AOKP build 14. Screen 10% brightness and full HSDPA signal.

Screen on idle, it dropped 1% after 4 minutes.

Browsing it lasted 2.5 minutes.
[Samsung Galaxy Nexus] Elganja:
that's roughly what mine is... so it appears that is just normal. that is all I wanted to confirm
[Samsung Galaxy Nexus] jknisley:
Well, I *think* I've done those things. I'm getting about 20% drain overnight, at this point, which is down from 50%, so I'm seeing that as a fast improvement. Is there any way to check what's registered with the Location Service Provider, or really anything else within the umbrella of "Android System" ? Or is it just look for "Android System" in the partial wakelock list?
[Samsung Galaxy Nexus] mDroidd:
Franco?!

you are getting lazy.

2 days after your last release, still no udpdate!!!

just kidding, I see many ROMs having last update 31Dec

Thanks for all your work! and I thought you would post a picture of you with maguro?

Awesome kernel when it comes to battery and performance. Best battery life out of the recent releases. No lag and very smooth
[Samsung Galaxy Nexus] evostevo1:
This kernel seems to work buttery smooth on 4.1.2 , but can anyone tell me if its right though?
[Samsung Galaxy Nexus] SahilC:
Try using trickster?

[Samsung Galaxy Nexus] Shadow-Nexus:
This kernel is really killing my battery and even with the 384 version and using the lazy governor

Any suggestions?
[Samsung Galaxy Nexus] evostevo1:
Try deleting battery stats in recovery.
[Samsung Galaxy Nexus] Shadow-Nexus:
I do it every time I put in a new battery since I have 2 spares through the battery calibration app and nothing it stills sucks
[Samsung Galaxy Nexus] evostevo1:
It takes a few cycles to fully calibrate though.
[Samsung Galaxy Nexus] osm0sis:
Somehow I think your battery stats are still messed up. The fact you use multiple batteries and are experiencing this problem can't be a coincidence. Those apps are generally garbage, stats can be wiped from recovery.. that's just for reference though, since Google engineers have said that wiping your battery stats should never be done. Instead, simply run it down until it turns off, charge it all the way up, then leave it plugged in a few extra hours once it reaches 100%. We had a discussion on this recently, and that's apparently when the calibration occurs.
[Samsung Galaxy Nexus] Shadow-Nexus:
Should I do this with all my batteries?
[Samsung Galaxy Nexus] osm0sis:
No. It is possible that the poor stats file has all your batteries charging below full and they need recalibrating, but there is only one stats file and the reason it is likely screwed up is because you have so many batteries on the go, ie. it never knows where their charges are at. My recommendation is to try sticking to 1 battery for a few days. Calibrate it like I said and just use the one and see if things improve.

No problems with battery drain on r283 here, so hopefully that'll help the issue on your end.
[Samsung Galaxy Nexus] Shadow-Nexus:
Which version of nightly 283 are you using?

512 or 384?
[Samsung Galaxy Nexus] gaich:
Final results with 283

[Samsung Galaxy Nexus] Neo3D:
Are we talking about Battery Stats? If so, it's a myth. It has nothing to do with recharging or calibration:

https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT

If you were having problems on r282, try a different nightly. I had problems with r282, my phone reboot 3x and everything was running kinda slow. Trying r283 for a few days.

Is anyone using the lowest 230mhz setting for the CPU? Maybe that's my problem causing instability?
[Samsung Galaxy Nexus] HeliosAI:
Gotta say kernel r276 is incredible for battery life. Got screen on time for 3.5 hrs! Head and shoulders above my usual of barely over 2 hrs (on other kernels).
[Samsung Galaxy Nexus] StuMcBill:
For some reason my phone is freezing a lot with this 283 release. Is there anyway I can troubleshoot what is happening?

Also, I find that the top of my phone screen, basically just under the speaker gets REALLY hot when I am using the phone normally (screen on).

Any ideas / advice?

Sent from my Amiga 500 using Workbench!
[Samsung Galaxy Nexus] PsychoAssasin:
I just flashed r283 this morning and have gotten just under 3hrs screen time before hitting 7% battery left. Very sinilar to r276 which was what i was using before although i think r276 was very slightly better battery life wise. Speed i would say is about on par as well since i havent noticed any major changes. I run everything stock except maxfreq of 1.3ghz
[Samsung Galaxy Nexus] dynamicpda:
I'm seeing the same problems on HDXenon XV with r283, both 512 and 384. I switched to lean kernel r4.4.0exp1 and I don't see the same problems. (I've been using Franco kernel without no break since Milestone 3? at least with no problems until now.)
[Samsung Galaxy Nexus] Puzzlegirl:
No freezing, lagging or heat here on r283 and battery life is excellent, the best I've been getting for a good few nightlies. I didn't get on well with r282 though and started using 729 to 1228 MHz, which I'm still using currently with interactive. All in all, brilliant kernel - thanks Franco :D
[Samsung Galaxy Nexus] nuwan32:
get a logcat and post it here for franco to see.
[Samsung Galaxy Nexus] CADude:
Its odd how 282 and 283 seem to have an equal number of people who have problems with them and don't have problems with then.
[Samsung Galaxy Nexus] dannejanne:
Great kernel. Spotify handles well at 230Mhz max screen off frequency. Just had to up the voltage to 1100 for that frequency.

I also think the audio sounds much deeper with this kernel. Is it possible for the audio quality to differ between kernels?
[Samsung Galaxy Nexus] msfan01:
Hello,

i have a little noob Question: Can i flash Francos excelent Kernels for 4.1 JB on AOSP 4.1.2?

Greetings
[Samsung Galaxy Nexus] leets4uc3:
282 and 283 have both been fine for me. Quick and smooth and just like usual.

Works fine with 4.1.2 aosp
[Samsung Galaxy Nexus] dehein:
Are there any updates you could use from android 4.1.2 kernel?
[Samsung Galaxy Nexus] doomed151:
Yes.
[Samsung Galaxy Nexus] chrisgtl:
Also lots of strange battery drain for me with #283 - Rasbeanjelly ROM.

Nothing is keeping the phone awake, I have normal hours in deep sleep according to CPU Spy. Better Battery Stats shows no partial kernel wakes.

Went to bed on Monday night with at least 35% battery left, 8 hours later when waking up my phone is off with completely dead battery.

Went to bed on Tuesday night with 33% battery left, 8 hours later when waking up my phone is off with completely dead battery.

Very strange, all I have is Gmail sync nothing else. All my other apps are logged out so no notifications/sync can be made. My ROM battery stats show a steep battery drain graph all day long.

Going back to #276 to see if my graph goes back to almost level when in deep sleep.
[Samsung Galaxy Nexus] slvrarrow:
Although I've not seen battery issues I can't help but think it's something to do with the recent vfs cache pressure changes.
[Samsung Galaxy Nexus] schizophrenia:
actually i have similar thing

nothing much runs in background (the phone isn't even online) but battery drain is faster than normal.

i posted about it earlier

but again, i am not saying it's the kernel

i just wanted to share and see if anyone got any insight why

please let us know how your testing turns out
[Samsung Galaxy Nexus] Dr Byte:
Same thing here; built in battery stats and BetterBatteryStats agree, as does JuicePlotter - my phone went on a nosedive for six hours... exactly. At 9am it woke from "overnight" mode and turned on wifi/data/sync and immediately went from "flatline" to a dive. No apps running, no wakelocks, supposedly 96% "deep sleep."

So "Nothing" consumed the power on record, but it burned up anyway. There were two short spikes of activity during the dive (which was mathematically straight) where some apps updated. I would have expected to see dips in the % graph when those happened.

The built-in Battery stats showed the phone screen OFF and only awake for trivial amounts of time. No screen time at all in that window.

Just as suddenly, it stopped at 3pm when it switched over to 3g data when I left Wifi coverage, and has been normal ever since. I only thought to look because the battery level was so low, about a day beyond where it 'should' be.

Battery is an Extended one, and hasn't been out of the phone since it arrived, nor did it reboot during that time (uptime over 24 hours - ie, installing 283 from 276.)

The only other "atypical' event was that Lookout had a notification open to tell me about a new feature after its update.

It may be Wifi driver related, or simply an event triggered by switching it on/off.

Reported in full, just in case someone else sees the same thing and notices a pattern.
[Samsung Galaxy Nexus] --__LoRiS__--:
I noticed a difference over build 276 (or 277...I don't exactly remember) during night with previous build, battery drain of 0% today battery drain of 1,5% for hour...why?
[Samsung Galaxy Nexus] franciscofranco:
People reporting battery drains, were you using Wi-Fi when the drain occured?
[Samsung Galaxy Nexus] Shadow-Nexus:
Sometimes most of the time I was on 3G
[Samsung Galaxy Nexus] franciscofranco:
Very strange to be honest, I really don't know I got awesome battery life grrr.
[Samsung Galaxy Nexus] StuMcBill:
I'm on HDXenon too! I wonder if it's something to do with that?

I have tried to get a logcat, but every time I record one with catlog, the freezing doesn't happen!

Is there any better way I can obtain one?

Sent from my Amiga 500 using Workbench!
[Samsung Galaxy Nexus] --__LoRiS__--:
I don't use WiFi during sleep... I remember that I was impressed for no drain during night!
[Samsung Galaxy Nexus] franciscofranco:
Users reporting unexplained drains please flash this and see how it works: http://minooch.com/franciscofranco/... Bean/experiments/franco.Kernel-r284-test.zip Thank you.
[Samsung Galaxy Nexus] schizophrenia:
i am not really saying it's related to kernel so dont take me wrong

the only variables between days ago that my idle battery was normal are:

1. new kernel version

2. i dont get wifi/3G data because i am at overseas

all others are constant

and yes, my idle battery drain without both wifi/3G is worse than with wifi on in a week or so ago

I have yet to test the idle drain with wifi on as I haven't got the chance
[Samsung Galaxy Nexus] P30SiNa:
I also have strange battery drain!I charge my phone twice a day after the new nightly!!

I'll try r284-test thanks.

btw I don't have any wakelocks.
[Samsung Galaxy Nexus] stoske:
I was on CNA 3.6.6 and 277 kernel for some time, and battery life was excellent. But there was some lags (in settings menu, opening some apps...) so I triend 283.

283 version is faster, no lags at all, but I also noticed little battery drain.

ROM is the same, as well as modem.
[Samsung Galaxy Nexus] franciscofranco:
Yeah I think that r244-test fixes it. Its important as if I confirm it it will ship correctly for M6.
[Samsung Galaxy Nexus] stoske:
I will flash it right now and send you a feedback.:cool:
[Samsung Galaxy Nexus] --__LoRiS__--:
Franco can you tell me all your kernel settings? I will try to compare r283 and

284 and give you a feedback. Thanks for your excellent work :)
[Samsung Galaxy Nexus] franciscofranco:
I use the same settings I ship with the kernel.
[Samsung Galaxy Nexus] The Gingerbread Man:
Battery drain caused by phone being in bad signal area searching for better signal. Try switching radio, ULIE1 has been good for me. Also, why don't you charge every night so your ready to leave the house with 100% everyday?

[Samsung Galaxy Nexus] 11768:
Me! :D

Previously, I was at 230mhz to 1306mhz and recently change to 729mhz to 1036mhz as recommended by some member here, feel smoother but battery wise for me is no good. Full wifi usage only give me close to 3 hours screen-on time.

Now going back to 230mhz but underclocked to 1036mhz. :good:

[Samsung Galaxy Nexus] franciscofranco:
That dmesg is from cm kernel. If you were playing for a while it might be reboot due to temperature? Dont undervolt too.
[Samsung Galaxy Nexus] schizophrenia:
cm kernel? hmm

but i am on r284-test and i have never downloaded or used any other kernel besides franco

actually i always play games for long and never had an issue with temperature.

i mean it's hot but not that hot.

thanks anyway

just reflashed and hope no more rebooting
[Samsung Galaxy Nexus] slvrarrow:
How many backported useful features from kernel versions above 3.0.x are included in your kernel Franco?

It seems the likes of faux has a lot from future kernel versions and I'm wondering how much we've still got to come performance wise
[Samsung Galaxy Nexus] nuwan32:
I use 384. There's only a 25 mV difference but the performance is noticeable
[Samsung Galaxy Nexus] schizophrenia:
just noticed the r284-test is a 384 kernel? noticeably slower on game.
[Samsung Galaxy Nexus] dannejanne:
I do. Max screen off freq. at 230Mhz.

At first Spotify stuttered quite a bit when having that low. But i upper the voltage for that freq. to 1050-1100 and the stuttering pretty much went away even on that low frequency.
[Samsung Galaxy Nexus] franciscofranco:
I think its 384mhz yes, I didnt even look to be honest, just wanted to get it out to get some feedback regarding the battery drain reported by some users :)
[Samsung Galaxy Nexus] yellowdie:
Wait a second. So instead of running 384mhz at 1025mV, you're running 230mhz at 1050mV?!?! Ummm...:eek:
[Samsung Galaxy Nexus] Neo3D:
Okay, maybe I'll go to 384 then. I was wondering why Franco set the default to 384 instead of the lowest possible 230?
[Samsung Galaxy Nexus] franciscofranco:
For that same reason ;)
[Samsung Galaxy Nexus] osm0sis:
I think because that's Google's default min and probably makes things a little less laggy.

Edit: Haha, what Franco said.

r284_test seems nice and smooth. I wasn't experiencing any weird drain with r283 though, so I can't comment on that one.
[Samsung Galaxy Nexus] franciscofranco:
r284-test killed the microlag you reported some times after r277?
[Samsung Galaxy Nexus] osm0sis:
Seems smoother in the widgets and Settings scrolling. Could just be luck?

I even noticed that with r283 it felt smoother after a bit of usage.

Best I can describe the areas of generalized minor lag I saw in r283 vs r277 are:

- mostly the app drawer being a little slow to get started moving,

- paging through widgets chokes more,

- homescreens feeling slower to switch between,

- the "hiccup" in Settings as it hits the accounts section when you scroll down fast after a fresh boot is more noticable.

With r284_test doesn't seem to obviously lag as much somehow with the widgets drawer and the settings hiccup, so it's smoother, but still seems slower than r277 with the homescreens and the app drawer getting started moving.

Let me guess, you changed nothing? :p
[Samsung Galaxy Nexus] franciscofranco:
Ok good. Yes I changed something!
[Samsung Galaxy Nexus] 11768:
Noticeable during what operation?
[Samsung Galaxy Nexus] nuwan32:
What.. I run 230 at 775mV and my 1036 is at 1025mV LOL
[Samsung Galaxy Nexus] rodnar77:
i can confirm this also helped me... so i guess i have to flash this after every Franco nightly...?

minor inconvenience for a super kernel!!
[Samsung Galaxy Nexus] slvrarrow:
Micro lags for me reduced too. I always test a scroll of either this thread or the android development section on desktop mode in stock browser - much more infrequent "micro lag" now compared to (especially) 282
[Samsung Galaxy Nexus] osm0sis:
Nope! Either use the updater app, or if you really want to use the flashable recovery zip then just open it in WinRAR/7zip and delete the /system/bin folder from it. That dir contains the sdcard binary, so it won't flash over your working stock one in the future if you do that every time. That's how I keep my latest version zip on my HD.

Agreed! Default voltage for 230MHz is 820mV, bumping it up to 1050mV is definitely bonkers.
[Samsung Galaxy Nexus] yellowdie:
dannejanne said they run 230 at 1050-1100. lol

AWESOME!! :D :D Thanks! (I'm out of Thanks again... :()
[Samsung Galaxy Nexus] joaquinf:
Batt drain while idling and connected to wifi seems very good. Unfortunately i can't comment anything about kernel wakelogs because betterbattstats does not provide any info after a kernel flash if i don't plug the phone. But this release is much more batt friendly IMO.

Performance is great as usual franciso. No noticeable difference
[Samsung Galaxy Nexus] osm0sis:
Update BBS? The new versions should fallback to "Since boot" as a reference point, so no need to plug anymore. :) :good:
[Samsung Galaxy Nexus] sruel3216:
nothing i hate more then the hicups when scrolling fast in settings and throught the widgets in the app drawer. I can never seem to find a kernel that completely gets rid of that. il try 284 and see how it goes
