stock kernel - Nexus 6 Q&A, Help & Troubleshooting

Dose the Stock 5.01 N6 kernel idle with 2 cores ? I'm watching it with prefmon app and its idiling at 300 with 2 cores always on .

you forget, stock uses mpdecision, so its always changing your cpu speeds(and cores used) as needed. and if its idling with 2 cores always, so what? my cpu idles with 4 cores always on, but thats just how i have it set.

No I no but I don't remember ever seeing any Device (stock kernel ) idiling with 2 cores . Just seems strange even with mpdecision . idiling on home screen with nothing running , doesn't seem right .

na, its alright. you wont lose extra battery because of it, if thats what you are worried about. many custom kernels include this as well, since there isnt any difference in battery loss.

Not worried about battery , I don't think its the normal behavior for stock kernel .

i go back and forth from ElementalX and stock , I no ElementalX runs 2 cores now but I already flashed back system IMG and boot img so ElementalX should be 100% gone . But ya hopefully there's still stock kernel users here on XDA ;P

Mpdecision idles 2 cores.

I think you are right, it always has some awake states while not even using the phone. It's not really worse tho, but battery management could be more efficient.
@main poster: the CPU Governor also makes a large difference, which one are you using?
anyone tried antutu cpu master? set your freq to the lowest when idle....it works better with juicedefender installed

Well. a CPU Governor manages the CPU speed,
for example, governor ondemand: when idle 245mhz when any action happens on phone, 1400mhz.
another example, governor performance: always at 1400mhz (uber fast battery drain but high performance all the time)
smartassV2 has a more complex way of managing speeds, it adjusts the speed according to the actions on the phone. it's a nice CPU governor and saves you battery. I'm currently using interactiveX as CPU Governor and vr as I/O schelduler, also gives fine battery results.

Drivers of XXKP4?, Those are the same as the XXKPG Drivers because it they were different your device wouldn't even boot (except for gpu drivers)

To be honest, the meaning of baseband is eluding me right now (as I am kind of new in smartphones biz).
But what I did is to flash XXKPG and right after that the "SMD_MODEM_I9001XXKP4_CL374422_REV00_user_low_ship_EMMC.smd" part from XXKP4.
I did that because the wiki is stating that
- "MODEM/PHONE is independent of the OS contained in the PDA, making it possible to mix-and-match MODEM and PDA versions from different ROMs, sometimes jokingly referred to as "FrankenROM". This can be useful for example if a specific MODEM version has drivers that conserve the battery better. Currently the I9001 MODEM reported with the longest battery life is the one included in the 2.3.4 XXKP4 ROM."
and someone said in XXKPG dedicated thread that battery life problems could be easily resolved flashing MODEM from XXKP4.
The logic result is that the two parts are somehow different...
If I am wrong, please explain.
Thanks.

the idle drain is high in the first 4-5 hours, i lose around 7-8% , then in the next 5 hours i lose about 3% , so my point is if i leave my phone on standby for 10hrs it will appear as if i'm losing 1% /hr , but if i wake it before i realize it's draining much more. using stock kernel and with radio ON through the night, and i kill all apps before putting it on standby.
starts with 90% because it crashed when i modified status bar and battery icon

[TUT] How to raise temp_throttle_skin (battery throttle)

I AM NOT RESPONSIBLE FOR ANY DAMAGE THAT RESULTS FROM USING THIS TWEAK, RAISING THE THRESHOLDS OF BUILT IN SAFETY FEATURES MAY DAMAGE YOUR DEVICE
I saw a few people have tried to alter this file with no success, weird when its the same permissions as temp_throttle and temp_shutdown. Here is a working method to alter this value, to be entered in terminal:
su
cat /d/tegra_thermal/temp_throttle_skin > data/local/tmp/temp_throttle_skin
echo 50000 > data/local/tmp/temp_throttle_skin
cat /data/local/tmp/temp_throttle_skin > /d/tegra_thermal/temp_throttle_skin
Click to expand...
Click to collapse
This tweak helps performance especially when charging, but be aware other parameters or kernel bugs can cause poor clock speeds and core use
Notes:
Do not use "echo 50000 /d/tegra_thermal/temp_throttle_skin" as a shortcut, this doesn't work.
I told the devs of tegra overclock about this, it's coming in the next release
If you are not sure if it worked just go to /d/tegra_thermal/temp_throttle_skin in es file explorer and open it as text, you will see it's current value
To set this at boot you will have to make an init.d script, otherwise you can open your terminal preferences and paste the command in "initial command", this way as soon as you open the terminal the commands will be executed automatically

ofc, just a note, you'll have to run this command every time you reboot, or make init.d script. thank you for this :good:
btw, just wanted to say, changing this value doesn't remove throttle for me. i still get throttled down at 40ish temperature of battery (on werewolf stock version, and yeah, the file reads 50000, or whatever the value i put in)

i've just tested iodak & werewolf, both throttle down at, what i presume, is around 40c battery temp. doesn't matter which governor i use.
stock rom, 20a, if it's of any use.

no problem, man.
i just can't understand what the problem is for me, and why it's not working. on PH85's kernel, i dont get throttled almost at all. his tegra_throttle_skin is set to 48000 on boot. iodak and werewolf are on 43000, and i get throttled almost as soon as i start using the phone for something that uses all four cores (it's quite noticable on benchmarks f.e., since it will often throttle during the test itself :/). i tried your method of echoing to temp file then echoing it back, tried root explorer text editor, and saving it. the file shows the change, but no change in the performance.

Well you verified it changed the value so theoretically it should work. Does the value stay the same when it throttles? Try leaving the terminal window open to force the value to stay

Another one its not working for!? Maybe I did something else, but I don't think so... Perhaps the problem for you guys is the throttling is caused by something else
Sent from my rooted P880
I must say I still occasionally get this throttling, but nowhere near as often. I think for this value to work all the time it has to be the kernel default. I find when I set it at boot it seems to work, but if I forget and it throttles, enabling it doesn't help. For those on CPU variant 2 and above use ph85, it has skin throttle @48 default. I am variant 0

Well.. he said right.. don't overclock too much. You can but it reduces the life of the phone hardware (from what I've seen ). You can overclock when you need it during gaming and then underclock after it.

And it is not 2.222GHz, it is 1.2 GHz. 2.2GHz will burin your phone... But I think you can get those values anyway.
AFAIK, there is no significant effect of overclocking on the CPU.
My previous device has 600mhz CPU and I overclocked it to 824mhz and used it for 2 years without any problem(it got stolen after that..?)
Also the capacity to which your cpu can be over clocked varies from device to device.
Again taking my previous device as an example.
For some people, it was stable at 824mhz but some people got many random reboots if they increased the frequency above 729mhz.
So basically we all have to find that frequency above which the phone starts rebooting (it may vary from person to person) by proper testing.
We shouldn't really bug cocafe for these reboots.
Tl;dr: the maximum overclock frequency at which we have no reboots varies from device to device.

Exacly, I forgot about that. For example my PC CPU can overclock to 3GHz at stock voltage. For 3.1GHz I need to pump it up and it heats alot more... So there is some wall. I am sure that is the case for phone CPU too, some can be OC-ed to some point, some can't.
It has been said that OC reduces life of CPU, but I keep my PC CPU overclocked since I bought it - 4-5 years ago. It is still alive. And now it cost like >10 beers in cafe.

[Q] Undervolting help

Hey I'm new to this undervolting thing. I believe I just undervolted by -25 globally using kernel auditor but my mV numbers in the boxes don't match the ones in this video(https://www.youtube.com/watch?v=T8THaPMp2ao). For example my bottom box 1040mV but the video's is 1010mV. Can someone please tell me what I did wrong and how to fix it?

If the app doesnt tell you, Wipe data on the app and reboot. Stock voltages are applied every reboot, until the app applies custom.
find out what you devices bin number is, then youll know what voltage chart your device should use.

Undervolting isn't going to do much of anything for long term battery life. CPU's are very minimal battery users for most day-to-day operations, so your actual battery life gains are going to be minimal, <5%, if you notice anything at all.

I'd say even less than 5%, more along the lines of less than 1%. but its decent for lowering temps slightly as well. me, I dont undervolt at all, yet see from 5.5-6.5 hours screen on.

All CPUs running??

Is it normal for all four cores to be at 13+% constantly? Can anyone clarify how the 821 runs? I'm on stock 4.0.3 OOS. I was trying to see if I could run completely stock -- but not seeing what's using CPU is driving me crazy.

Yes, it is normal! OP3T does not hotplug on load, so yes, all four will be active.
