Hello,
I have Mahdi ROM, and tried this kernels: Hells Core, Matr1x and Ak. But my phone go very hot and the battery drain tot fast.
Phone is rooted, I run Greenify, Gmail and WhatsApp. Sync is off.
Is there any good and friendly battery kernel?
Without go to hot?
I have nog this settings in Hells Core.
Min: 384000
Max: 1026000 with ondemand
GPU: 128
Undervolted begin with: 65000

too hot says nothing. whats the cpu temp?
anyways, if your phone gets too hot, it will hit the safety shutdown and turn itself off. anything below that temp, is not too hot. you have a quad core phone, its normal for it to get hot. with using cpu or gpu intensive apps, it can get extremely hot, and thats normal. tyhe n4 also has a glass back, and for a reason, to cool off the phone. the heat gets transfered through the glass to the surrounding air. because heat gets pushed through the back glass, it will feel hotter. again, if your phone was "too hot", it would shut itself down.
anyways, cpu shutdown temp is 100C, and you arent anywhere near it.
your battery drain is unrelated. battery life all depends on how you personally use your phone, how you set it up, what apps you use, and very much the quality of your phone/data connection.
Don't worry about the temperatures. I don't know about you but during the summer my phone heats up a LOT, and that too very often, but it doesn't harm the phone
has simms22 said, the way the phone is built you get the feeling that the phone is really hot in this time of year
the battery drain depends of the use but if it is really draining fast while idle (like 6-10% for hour IDLE) and the battery charging is inconsistent then you may have a problem with the battery

It might not be normal, and the battery consumption may be related. I had a similar issue a while back after updating my carbon to a latest nightly, I started getting very poor battery life and the phone used to get too hot (just hotter than normal), when I checked the battery consumption, it was Google Play Services and its wakelocks.
@OP, check what's eating up all your battery..
I find that Franco kernel offers a perfect mix of performance/battery.
Apart from that I'll repeat what others said. Due to the design the nexus 4 often feels hotter than it actually is. But I can assure you that nothing will happen. If it really reaches a temperature high enough to harm your hardware the device will shutdown automatically. But it's likely you'll only reach such temperatures while running benchmarks at full power and over clocked.

Hello,
I have a peculiar problem with my OnePlus Two
The faster A57 cores don't get activated, I have tried using Antutu, played Asphalt 8 And NFS NL for hours.
But the cores just won't get triggered
I'm using A1 CPU tool to monitor the same.
Even CPU Z wouldn't show me any activity on the other 4 cores while Antutu was running.
Any ideas? It's brand new can be returned

I just installed A1 CPU to verify your issue.
It shows cores 0,1,2,3,4 are used at 1344ghz for me as well.
When i check with synapse (i'm on AK kernel) it shows all cores are used.
I guess it's a limitation with A1 CPU tool. Try with other tool that supports such architecure.
I was sceptical on the same but, out of the box I remembered seeing 1777 MHz frequencies.
Thanks a lot
I shall try more tools and get back.
Though I think if you're on a different kernel and had the A1 CPU tool been correct it would be redundant, Because core allocation would be done on kernel level (in my knowledge).

I know that it was already discussed but maybe someone has found a solution.
The problem is that performance of device gradually decreases proportionally to the level of the battery.
For example:
- battery is 90%, Real Racing 3 runs perfectly,
- battery is 45%, some lags appear during gameplay
- battery is 10%, heavily FPS drop, almost impossible to play
Battery saver is turned off, device is cold in all tests.
If I would like to save my battery level - I will turn on battery saver manually,
but I WANT to have good game experience not depending on battery level
This is really crazy.
Tested on stock OOS 2.1.1, with stock kernel, with Boeffla an AK, tested on Exodus ROM - everywhere I can see this weird behaviour.
May be some system files must be edited to overcame this issue?

Hi Jemcik, hi Denhot!
I'm facing the same issues on my new device and it's definately not normal!
With a battery level of 19% I was not able to get the 4 A57 cores online, which results in lower system performance. Have you found a solution?
@Denhot!
Maybe we should rename the thread into: IS OPT PERFORMANCE REALLY DEPENDENT ON BATTERY STATUS AND IS IT A ROM FEATURE OR AN ISSUE!?
I think, one of the kernel devs should be able to answer this question.

It looks like some system configuration files with kernels activation policy have to be edited,
but I haven't found yet which files exactly.

I've never experienced such a function!
CPU power depending on battery voltage!? 62k with full battery, 49k with 20% battery both with same CPU temps!
Hopefully not a general problem on our side with the motherboard Voltage Regulator or something.
Have you been to a kernel thread and asked this question? If not, I will ask this in AK's kernel thread. Maybe he knows more about it!
The 4 high performance cores will only be activated when needed. What app are you using to check the core usage? Every now and then you should see 2 of the high performance cores sometimes coming to life every now and then, with the other 4 power efficent cores being more busy. Use CPU-Z to check.
Due to the way Oxygen OS's stock kernel works, only 2 of the high performance cores will ever be active, alternating between the 4 cores in an attempt to keep the phone cool and not throttle as often. If you want all 4 high performance cores to be active as well as overclocking it back to its original speeds, you'll need to flash a custom kernel.

Hi,
would like to share I don't have a similar experience, with NFS NL or Asphalt, phone was consistent with no lags even when it got unbearable to hold.
I as playing and simultaneously screen mirroring over to a TV.
Going from 65 to 25% over a long course.
I normally won't let my battery fall below 20%.
So the thing about Li-ion/pro is that as you go lower voltage decreases so to provide same power draw current increases.
Basically it would heat up faster.
That can be a reason combined with that their might be inbuilt measures to save battery like you said, nor as an engineer I would recommend you to stress your phone at those levels.
I can't explain the lag at 45%, didn't find it might try real racing 3 later to check.

This is consistent with what I've noticed. The time It didn't, a simple reboot helped solve it and it hasn't occurred since.
Also these tools can't monitor the other cores, if you're rooted why not try synapse as helkat suggested

Thanks man!
I know how the S810 should work!
But I thought the performance issues have only to do with the temps. But now it seems it have also to do with the battery level.
It would be good if someone tries to reproduce the following to verify it:
1. One run Antutu benchmark with fully charged battery and room cool temps.
To be sure the conditions are the same, shut the display off for one or two minutes, than start display again, kill all recent apps and run Antutu test and note the results.
2. Than wait or do something until your battery is down to 20%, shut the display off for the same time, kill recent apps and start Antutu test run again and compare the results.
I've also tried the same after a reboot, with always the same results.
With 100% I get scores between 60 and 66k and with lower capacity (20%) I get only 48 till 50k!
I am not interested about the benchmark results, but I need to know if this only occurs on my side.

So, guys!
I have tested it the last few weeks and it is a fact that the performance in benchmarks is dependent by the battery level.
We have tested it with 3 devices and it is always the same.
But thank God, it seems on the devices perfomance themselves (in apps/ui) this has no effect!
But each one can replicate this behavior very easy!

I have the same issue! When battery level goes lower than 20%, my A57 kernels become offline. I checked this with CPU-Z and PerfMon. And this is the same on stock or custom kernel. Now I am using Boeffla kernel. The most frustrating is that my UI suffer from this. I have lot of lags in simple apps, such as calculator or some messengers.
Same issue here, there are threads in one plus forums.
I think the threashold level is at 40 % ?? They made this to keep the battery up. You can also see faster battery drop till the 40-30% mark then it is harder to kill the battery.
I am also dissapointed in this, maybe we can search the kernel sources ? Or is there a daemon app that triggers this?
I received the phone with 20%-30% battery, started an antutu knowing how powerfull 810 chip is, then boom 45k same as the previos phone i had with 801 chipset...i was like what the fxck....runing antutu again with full battery - 66k.
well i have run benchmark in back ground with few game and apps .. and checked with cpuz max that i have notice was around 50-60% cpu load still 2 off those a57 cores were off using this device for 2-3 days it always turns off 2 cores for me rest 6 is working most of the time :/ Even in battery saver mode .. i am not sure if this is a cpuz issue as i have not rooted my device yet so cant say properly ..
Also i face some freq. benchmark issue like in benchmark it scores around single core - 690 multicore - 2.6K .. and if i restarts device it scores normal - 1.1K and 4.5K .. i have no idea whats wrong with this :/
20% Battery Mark
The drop in performance at 20% Battery is standard behavior of the Rom and Stock Kernel. The Big Cluster (A57) is completly shut down to save Battery. If you dont want this you have to use a custom Kernel which is able to switch this Battery saving strategy off. Boeffla Kernel for example can do that.
Read http://www.anandtech.com/show/9828/the-oneplus-2-review/2.
They "optimized" the soc.....
No they just turned off some cores so there is no heat problem.
So I think this is my first and latest oneplus.
they've hit the mark! What the hell, i think they must be sued for false marketing. Its just like buying a car with 400 hp and those hp are only there when i'm parked or listen to music, if i'm on the highway or on the ridge the car has 100 hp...wtf :|

Calm down lol it's actually good on their part. Shutting down A57 cores on low battery is a good thing because the A53 cores use much lesser battery. If you're out on a trip and have 10% battery, with the A57 cores this will probably drain off within an hour of intermittent usage. When only the A53 cores are active, the battery life will increase greatly.
Companies design phones for average users, not just gamers. If you don't want this feature, root your phone, flash boeffla's kernel and disable the BCL Battery Driver. It's as simple as that
Hey i tried many diffrent rom bui i can only get 2.5h SOT. Which kernel do you use and which rom to get the maximum battery life without lag?
Battery<----------------------------------->Performance
They are at opposite ends. If you want maximum battery life then there no way to avoid lag.
You can completely turn off 2 or 3 cores, leaving you with a single or dual core phone;
You can also underclock and undervolt the remaining cores, reducing power consumption even more.
This is very battery friendly (in theory), but, as I said, it will give you big lags.
I added a rom video review to the help thread. You might want to check it out.

Do you have any better ideas on how to increase battery life?
Cores need power to run. Turning them off is a completely logical option.
You really don't need all the cores for most tasks. You can browse Facebook, or whatever, just fine with only two cores.
I am currently running in dual-core mode with max cpu frequency at 1.2 GHz and it still is smooth.

Nothing.
Test your battery. Or better yet, start thinking of getting a replacement or a new phone. With a 2 hour charge something seriously is wrong with your device.
My 3 year old S4-i9500 still comfortably gets through the day. Bought a brand new original battery 6 months ago. Smooth sailing. No under-volting, shutting off cores, under-clocking or any crap like that. Phone is custom rom'med and correctly so if I may add.

You are aware that he said 2.5h SOT, "screen on time" ?
That means that after using it for an entire day or two, the combined time of the screen being on is 2.5 hours, and in my opinion that is not really bad.
The screen is always the culprit when it comes to power consumption, and in a phone with a battery that doesnt exeed 2000mah its just natural
that after about 2-3 hours of the screen being on the little battery is empty, and no ammount of undervolting will extend that significantly.
The only thing he can consider to increase SOT is a bigger battery, if he doesnt mind the bigger bulge at the back.

Had no idea - never really cared what SOT stands for anyway! But thanks for clearing that up. Always had satisfactory battery life on my S4. The few times I didn't was when a rom on my phone went bad & subsequently had to flash another.
So if what you say is true regarding a day or 2 battery life, then what is this chump complaining about? Turning water into wine? :silly:
So @GDReaper idea is right!I currently am on crDroid and when I switch off 2 or 3 cores the phone is as fast as it was and the battery lasts a little bit longer..With normal charging it goes to full for about 1 hour and half and without using it the batttery lasts 1-2 days,using it lasts about 3 hours or 4.I flashed a new kernel and turned on fast charging on Kernel Adiutor,now the phone charges full for about 45 minutes and lasts same! I'm very happy with my battery bcs I haven't changed it since I got the phone!
Hey all,
I was looking around in aida64 and I saw that the big core is always active. At idle it's staying at 633mhz. Only after boot I saw "sleeping" , but after few mins it just stayed at 633mhz. More people experiencing this? I'm on the second 7.1.2 beta.
Screenshot: https://s11.postimg.org/d2a4kcyir/Screenshot_20170324-090259.png
I'd like to hear your thoughts!
It seems that when they're stopped or sleeping, that's because of thermal throttling: https://forum.xda-developers.com/nexus-6p/help/4-cores-allways-stopped-whats-t3390543. So I guess they should always be running and not sleeping/stopped. If not, your phone runs too hot.
Would be great if someone can give a clear answer on this!
When the phone reboots it works hard to start the OS and apps and therefore has to thermal throttle to cool the cpu down. Once it fully boots and the cpu load is lower it cools down and the big cluster comes back online and idles at 633, the stock big cluster governor setting.

Thanks for the info. But what's up with this comment on Reddit then? "my nexus 6p is working properly on 7.1.2 apparently, my uptime is ~189 hours, 4 cores are on low frequency 384 mHz and the other 4, the A57s are sleeping, see the screenshot below.
http://m.imgur.com/UZhZxd8". More people are reporting this . So it seems that for some people it's idling at 633mhz and for some people it's sleeping.
Hi all,
I have cpu z installed and I'm not rooted. It generally uses all 8 cores but when I accidentally opened it I saw that it was only using 4 cores. I decided to restart and it is still using 4 cores. Is this normal because my g5 plus always uses all 8 cores.
Your in low power or battery saver mode... look at the battery symbol.. I can't remember if it kicks in at 5% or 15% battery automatically, then turns off when you connect the charger... It sometimes takes a few minutes for everything to kick back in. I would bet after getting a decent charge it was back to normal?
There is also a issue with Nougat at newer reporting CPU usage incorrectly even in rooted devices... been talked about a lot, something in the stock Moto firmware (or maybe that was a different Moto, I get them confused sometimes).
Ok thanks. Apparently cpu z was wrong.
the cores are reduced to 4 when u are on battery saver.
On thanks. The weird part was I didn't turn the battery saver.

It's automatic at a certain battery level by default.

It will throttle them, although the exact implementation varies somewhat depending on the actual processor. littleBIG architecture tends to be that the BIG cores get shutdown, on more standard architecture like the SD625 they will get throttled to 50-75% of maximum speed, and others may just get a couple random cores disabled, it depends on the CPU and how Qualcomm/MediaTek/whoever engineered it.
Ok thanks!
