It is not mentioned in the OP of the main thread, but somewhere in the thread.

Short explanation:

Setting A57 cores to zero means, the whole cpufreq subsystem for the cpu gets unloaded. As soon as at least one core comes online, it needs to be loaded again, and initialized etc. (you can see that yourself in the sysfs, where the whole tunables governor folder disappears and appears again etc.)

This is HUGE overhead which consumes quite a lot battery.

If you have at least one core always active, the cpufreq subsystem main parts stay loaded and usable, so the overhead is much less, hence less battery usage.

On top, the a53 cores need to do much more work, which in the end even needs more energy than the stronger a57 cores, although the latter are less energy efficient.

So it is a completely wrong assumption to think having zero A57 cores would help for battery, it is the other way round. We all learned that over the time and understand more and more the big.little concept mechanics.

Andi
[OnePlus 2 Android Development] gm.cinalli:
And you call that "short" explanation? LOL thank you very much for that complete answer!

So you plan to remove the 0-N hotplug profile for the A57 core in the next releases of your kernel?
[OnePlus 2 Android Development] andip71:
No, I don't plan to remove it.

Maybe it is good for some specific reason one day for specific users.

Hence I decided to put the warning message only, but not (yet) to take away functionality.

[OnePlus 2 Android Development] :
This is something equivalent to engines in automobiles: When you stop at a traffic signal, you do not switch off the engine to save gas. You bring it to idling mode and push the gas pedal (and shifting gears) to move again.

Whenever you fire up (start/restart) the engine, you need more gas and hence you end up burning more fuel than saving. Law of physics...
[OnePlus 2 Android Development] Lazdaa:
Not sure if this is caused by this kernel or my settings, but im being random reboots throughout the day. How can I figure out what caused this?

My settings

zzmoove

A53: 3 cores, 1.3ghz

A57: 0-2 cores, 1.5ghz

Thermal relaxed

Zan I take it that u have a oneplus2
[OnePlus 2 Android Development] TaRsY:
Please pull /proc/last_kmsg right after reboot occours, and post it here.

Otherwise you can change all settings back to default (be sure issue is not rom related) and start to set them one by one and test which one causes the instability.
[OnePlus 2 Android Development] zoroarctic:
Try a 1-2 cores setting on A57

A few posts earlier, Lord Boeffla explained how offloading the A57 CPU cores could consume more battery. Maybe in your case the stress of unloading them is causing reboots? I've used that configuration before and I haven't run into issues, but it depends on our usage, really :)
[OnePlus 2 Android Development] andip71:
On 3.10 kernels, there is no last_kmsg anymore.

Just for education [emoji1]

The new concept is called pstore.

When you create a debug info file, the pstore logs are contained.

[OnePlus 2 Android Development] mcc2005:
I use A53 with elementalx [MENTION=4691858]1.3[/MENTION] GHz and A57 with zzmove @1.5 GHz

and Thermal-Relax

All works like a charm. Have round about 5h SOT.
[OnePlus 2 Android Development] CrashTestDroid:
European cars offer start-stop. We don't have it in North America is because fuel economy tests ignore idling fuel consumption.
[OnePlus 2 Android Development] ZaneZam:
hmmm, we will see...

thx my friend actually didn't know about pstore, learned again! (or i forgot and learned again *gg*)

aaand [MENTION=4192744]Lazdaa[/MENTION] using boeffla app->action->create debug info file right after the reboot would be the easiest way to generate this

and then either attach it here or send it to me support-zz@boeffla-kernel.de (not to lord boeffla!! support@boeffla-kernel.de)

we have to keep that seperated and also have to spare the lord with pontential unstable stuff (well not that much actually *g*)

+ bug reports of it. thx for understanding ;)

[Samsung Gear S2] bishop72:
My watch is fully charged at the beginning of the day, 5:00 am, and 12 hours later it is down to 39%. I checked my notifications and did use the internal music player when working out for 30 minutes today. So was just wondering what everyone is experiencing with battery life.
[Samsung Gear S2] supersoulfly:
Think I can get 24 hours with the screen always on and wake up gesture set on. 2 days with wake up gesture on and always on screen set off.
[Samsung Gear S2] goobyjr9:
70%@24 hours with wake-up gesture, moderate heart rate monitoring, NFC and Wifi turned off, and lots of notifications.
[Samsung Gear S2] bishop72:
Wonder why my battery is draining so fast...
[Samsung Gear S2] integlikewhoa:
I'm at 70% after an 8 hour work day. Wake up gesture on, wifi, bluetooth on.
[Samsung Gear S2] refereeme:
After a day I get home with 33%. By bed time I am closer to 28-29%. No way could I get 2 days. This is with brightness low, although ambient still working. Gesture on, wifi & bluetooth on. This is the biggest disappointment about the phone.

Can I get through a day? yes. Can I get the claimed battery life? no. I do not get many notifications (maybe 15 emails and 10 texts a day on it).
[Samsung Gear S2] mobeast17:
Currently at 65%. Last plugged in was yesterday morning at 6am. WiFi off since its always near my phone. Wake up gesture on. Brightness at 6. I get a good amount of notifications too. This can easily last me 2 work days.
[Samsung Gear S2] CTBob:
Mine was at 62% last night so two days won't be a problem. Since it's new I'm still playing around with it and using more battery than is necessary. Put my wife's photo on the watch face just to see if I could. I did shut off WiFi since my phone is always nearby and NFC since that doesn't really work yet and I'm not sure I would use it anyway. I also turned off the turn on with notifications. Accidentally put it in a waterfall pond this morning doing some maintenance and am glad I don't have to worry about that aspect of it.
[Samsung Gear S2] goobyjr9:

[Samsung Gear S2] optimummind:
With brightness at 7, all connections on (WiFi, BT, NFC), screen always on, and receiving notifications, I finished yesterday with about 20%. The watch was taken off the charger at 6:45am and put down around midnight.

Today, I made one change and turned off WiFi. Watch off from the cradle at 6:45am and right now at 10:36pm, I have 31% left.
[Samsung Gear S2] refereeme:
Last night I was at 33% again (10:00 pm). I turned off the functions wifi/bluetooth/nfc and this morning I was at 20%. I am running it down today to see if that will help condition the battery (100-0 then full charge) and if it adjusts how the percent remaining is displayed.

I seem to remember that batteries should be usually kept between 20% and 80% with an occasional full cycle to help keep them conditioned. I'm no expert though so this may or may not be true.
[Samsung Gear S2] refereeme:
29 hrs and it shut down. Light use of the device.

-30 email/text notifications.

-15 hrm tests.

-screen brightness of 5.

-22hrs with wifi/bluetooth/nfc on,

-8hrs with it off (during sleep).
[Samsung Gear S2] CTBob:
61% left last night. 60% left seems to be my average. NFC off, WiFi off, watch on with notifications off, heart rate frequent. Basic watch-face with white background and date. Notifications from ESPN and texts.
[Samsung Gear S2] FitzAusTex:
Ending 18 hour days with about 35% in the six days I've had it. Brightness @3. BT and wifi on. Nfc off. Always on screen on. Tilt to wake, and heart rate off.
[Samsung Gear S2] CTBob:
Decided to try the always on feature today and ended the day at 31% instead of my usual 60% so this feature uses a lot of battery. Going back to not always on.
[Samsung Gear S2] scoobrel:
With the s2 classic, im at 38% with light usage, a few notifications, wifi off, nfc off, wake up gesture on and 50hrs and 22 mins off the charger.

Edit: brightness on 7.
[Samsung Gear S2] Meanee:
Varies a bit from what I can see. I took it off charging dock at 6:30am. At 3:10pm, I have 82% left. Always On screen disabled, brightness at 6, WiFi, BT, NFC on. First day, it was worse.
[Samsung Gear S2] Rafik Jabbour:
That is extremely weird. Just bought mine. Charged it fully through night.

- Picked it up at 06:15 @ 100%

- Wifi on, NFC, on, HRM Frequent.

- Brightness 7

- Screen always on

- Wake up on notification

- Wake up gesture on

Battery at 14:00 = 5%....

is this normal ??
[Samsung Gear S2] rlichtefeld:
Turn off WiFi, Turn off NFC, set brightness to 5, and you should get a LOT more battery.
[Samsung Gear S2] Rafik Jabbour:
Day 2:

Turned off (HRM, Wifi, NFC, Wake up on Voice)

Brightness set to 3

Picked it up at 06:15

Let's see the result.
[Samsung Gear S2] pigglett:

[Samsung Gear S2] Mønsters924:
How in the world do you get so much battery life?!

I bought mine a couple days ago and the first thing a did was turning off everything

- wi-fi off

- nfc off

- auto HRM off

- screen brightness 5

- gestures off

- voice off

- Screen timeout 15 sec

- vibrations low

Last night the watch was at 100% at 1 am and at 7:30 am it had only 36% left from doing nothing just laying around... Some of you guys going for 2 days, mine is not even able to go through half a day...
[Samsung Gear S2] skilli:

- Wifi off, NFC, off, HRM Frequent off.

- Brightness 1

- Wake up on notification on

- Wake up gesture on

- about 30 Notification a Day

about 60h to 0% Battery

What i noticed is that only with my Liongate Lazer Watchface the Watch lasts 2.5 Day long. With other Watchfaces its about 1.5 Days
[Samsung Gear S2] Mønsters924:
I maybe fixed my bad battery life I factory reset my watch I set it up like it was brand new. I restored nothing and I can already tell after couples hours that the battery life increased a lot. If it last me at least 24h+ I'm happy before the reset it lasted not longer that 8 9 hours at best.

Update : since my factory reset I haven't charged the watch, it's been 72 hours now and I have 56% battery left

Whenever an app asks for an update I am linked to the Xiaomi app store instead of the Google play store.

I am on China's 5.9.17 developer ROM.

Anyway to solve it?

Settings>System Apps>App Store

Go there & disable notifications and automatic updates.

I had already done that, everything was unchecked except "delete package" which I unchecked now.

For example if I di a research in chrome and that some of the results are app, I am linked to Xiaomi app store.
[Xiaomi Mi Note Pro] Kahun:
Don't think there is actually a way to go around it as it is a Chinese ROM because global one hasn't been released and there is no option to change the default App Store

That's what I thought although I was hopeful there was a kind of tweak

[Verizon LG G3] OstrichSak:
Halp!

I'm losing my mind trying to figure out the issue here. SMS works fine. Hangouts will only notify of a newly received message if you open Hangouts and are on the conversations list screen (main screen). If you are in a conversation it won't even update of the newly received message until you back back to the main conversations list screen. Doesn't matter if it's on WiFi or mobile data. This is a brand new phone that I bought about a week ago and for the record I'm using the same phone I bought a month ago from the same seller on the same firmware. The only difference is that mine is rooted and I've frozen or uninstalled most all of the bloatware and VZW bullcrap. Otherwise they're identical and one has what seems like an app bug but the other one does not.

I've tried numerous things before posting here (to include lots of searches that only seem to turn up similar issues for those who updated to Lollipop) including uninstalling Hangouts updates as well as Google+ updates as per one thread I saw. Neither had any affect on the issue. I went into the user's Google account to see if any other devices were signed in currently and it doesn't appear to be the issue.

My next step is to root and see if freezing the same apps corrects but where it sits right now would make a warranty exchange through the seller a little bit easier I would imagine.

I'm not really sure what else to try short of accepting the OTA update (Lollipop) which will w/o a doubt introduce more problems than it fixes based on what I've read. Not only that but my LG G3 is functioning just fine on 4.4.2 so I see no reason why the same device shouldn't perform the same on the same firmware version. Makes no sense.

Can someone help me out here?

Thanks!
[Galaxy Note 4 Q&A, Help & Troubleshooting] MrKurtz:
Guys I need help, IDK what else to do.

I bought my SM-N910C Exynos 5430 Note 4 about a month ago, everything was just fine, working perfect on stock 5.0.1. But then, a week ago, stupid me decided to root my device in order to block ads. I used CF-Auto-Root, the root was successful, but after that the phone started overheating even from light use, watching youtube videos, netflix, or a couple of minutes of hearthstone (or any other game) would turn the phone into a burning nightmare.

Out of frustration I decided to unroot my note 4, I flashed a stock version of android 5.1.1 and did a factory wipe and a cache wipe. After that things improved, the phone seemed fine, even more responsive than before, but i still felt some undue overheating while gaming or watching Netflix, nothing as bad as before but still noticeable. But then, earlier today I as was having a long call with my GF while I browsed the 9gag app (something I used to do before with no issues at all) and the phone got extremely hot... burning hot. No other app was running in the foreground. I´m really frustrated and desperate now guys, I feel I completely ****ed up by rooting, I not just ruined my guaranty, but I’m stuck paying an expensive phone that overheats horribly with even light use.

Please tell me there is a way to at least find out what the hell is going on, I would really appreciate it guys! Thanks in advance.
[Galaxy Note 4 Q&A, Help & Troubleshooting] dork997:
Try this.

1) flash twrp , go to wipe option hit "format data" then go to advanced wipe check dalvik cache, system, data and cache. Swipe to wipe

2) your phone will have no ROM at this point, go to sammobile download stock 5.1.1 firmware. Flash it.

3) If this does not solve your problem then this could be a hardware problem.

Anyone know of any firmwares that don't cause it? or am I doing something wrong?

They will cause bootloops unless you wipe data. Tick wipe data,cache,appslog in flashtool. When you downgrade from one android version to another, there is a 99% chance of a bootloop. However, you can usually upgrade without problems.
