I had my S2 set to 1.6GHZ and noticed very little battery drop compared to 1.2ghz (stock) so now I am just wondering if it would help me save battery if I set it to 800mhz?
Anyone know if this will help?
And for some reason SETcpu only detects the S2 as 1 core. So hopefully thats just an error and I hope I really have a dual core phone.
Which kernel are you using?
I am on Light'ning 6.1 (2.6.35.11 ninphetamine-2.0.5+)

Changing CPU speeds will not help you save battery. Undervoltaging (UV) will, however. UV only works on certain kernels, and you MUST know what you're doing before attempting to overclock and undervoltage simultaneously. Read up OC/UV guides around the forum to know more and the recommended speed/voltage pairings.

I'll be staying far away from that then. Thanks!
of course underclocking will give you a bit more battery life. even if you don't undervolt.
underclocking it to 800 simply forbids the processor to go up to 1 or 1.2ghz and it doesn't need as much power as in the higher states.
a normal desktop cpu also gets hotter if its overclocked with its stock voltage. But if you crank up the voltage too, to keep it stable it will get even hotter.

Well, Nordic hardware has done some tests. Undervolting CPU and GPU will not save your batterylife significantly.

Actually it shouldn't. A faster speed allows the CPU to finish the task faster and then go to sleep...

That may be true, but higher frequencies have a higher power draw, the phone at lower speeds should be able to manage with whatever the task is, assuming it's not a extensive app. If you're not a power user you don't need the phone to be clocked at the max freq, you can lower it and you see minor changes in battery life. With dual cores task are handled must better so 1.2ghz+ shouldn't really be needed, TouchWiz can't be as bad as Sense, where you actually need it to be clocked higher.
Oh man, Undervolting is OK but why would you Underclock a CPU? Now don't tell me it's too fast, don't need that speed in real world, you won't notice any difference and etc..If you are gonna Underclock it why did you purchase it on the first place?
Besides, that article said it all.
Regards.
For me I think underclocking + undervolting does indeed save battery life.
What I mean is that in my sig '1.6Ghz - 1325 mV' an at '800Mhz -950 mV' you see a difference of 375mV which I think can save your battery life for a couple of good minutes + 800Mhz is enough for my needs along with playing games (Only a tad slower at loading).
That's not necessary true. Yes at a higher frequency the task would complete faster but at the same time the processor with use more current and or increased voltage at the same time. That's why cpu's level up and down. Otherwise why not have the CPU set at 200Mhz-1200Mhz instead of 200-400-800-1000-1200Mhz.

Please set your computer on fire and never return to the internet ever again so it doesn't have to be filled with your stupid statements.
Also yes underclocking saves battery, anyone who says it doesn't is dumb, you wanna see for yourself? set your phone to 1.6 GHz all the time, according to you people this wouldn't significantly drain the battery any more right?
Undervolting saves slightly more battery than underclocking.
Also why would you underclock + undervolt the phone? Because it saves battery and you won't find any noticeable performance gains between 800 MHz and 1.6 GHz.

Hi people,
This thing is really bothering me a lot! I know what overclocking your cpu is but I really don't understand what's the exact advantage and disadvantage of it?
I mean when should we overclock our devices? While charging? While doing multitasking? Or while playing games?
Please.. I need some guidance on it!
Thanks in advance!

overclocking actually increases your processor speed so basically you overclock when u r playing HD games or while multitasking...
Disadvantage ...
you may damage your hardware if u constantly overclock.... so be very careful while overclocking....

While charging?? You think it will charge up faster?
Anw, as much as it's good, it's bad.
It's "same" in PC's and phones, why I say "same"? PC have one advantage, we call it cooler and vent's.
To get better info on OC: http://lmgtfy.com/?q=overclocking+pros+and+cons
Overclocking is basically making your phone's processor faster than it should be.
Advantages: Faster phone.
Disadvantages: Short life span of phone
Normally, if I overclock, I only increase it to a little more than My processor's stock speed and set the governor to ondemand. Ondemand means only if your phone requires more power it will use more. Be careful though, and DON'T go crazy with the overclocking
You only need to know one thing for overclocking
Never do it if you don't lag like E#@.

Read definition of overclocking
1GHz is not overclock, since its made to work on 1GHz by default.
Besides it can't damage it if (again) its made to work on 1GHz.

People are stating that the performance is much improved after flashing the kernel. So I want to ask how does GTA sanandreas run on the device is it comparable to the ONEPLUS ONE ? Could anyone maybe upload a short sample to youtube of the game running at max settings on the device with the Blu_spark kernel ?
Video I found of gta performance with stock kernel skip to 2:00 https://www.youtube.com/watch?v=NCfUUhp_M54
With Blu spark it's exactly as one plus one performance.

Possible yes but not with Blu spark. Noone working on it as far as I know. Eng.stk could implement it in Blu spark but does not want to, which is the correct decision in my opinion.

Why wouldn't it be the correct decision ? it could be completely optional
Yeah. I wish that someone would even make a 2.5ghz possible as optional. People that tweak with kernels usually know what they are doing plus one setting that is above the normal values would not even bloat it. Also we have thermal limit that will kick in that there will be no damage. It would be nice to experiment just a little bit.
Ps. Still one helluva kernel. Thanks to eng.stk
Great kernel. I use it on CM 13 with an incredible undervolt. I'd bet I could hit even 2.8ghz easily and stay under stock voltages. Loving it for everything else though.

Been my daily driver for a week. 729mhz was unstable so I had to raise it to 730mv from 725, but its great. Hence why I'd like more options for frequencies haha. I think I have an insanely high binned chip even though its an AA model. Can't wait to see what frequencies I can hit though.

925 actually works too, but I had a few bugs. Rule of thumb is generally 10mv above whatever works so I settled with 935. I will test 930 though. Had to raise 1900 to 910. 905 gave me issues in stability testing.
The Phone is stable at these settings.

excuse me for being a noob, but, what's the main advantage of undervolting the cpu? is it done to achieve a longer battery life? it does not limit performance right?
i'm a new opx user and just flashed this awesome kernel and i'm interested in boosting performances of this awesome device.

You dont want to use anyones voltage settings. Undervolting is random. Some people get amazing results while someone gets crashing.
Undervolting cpu makes the phone run cooler and will save a bit of battery also.
Less heat also means that the cpu will propably survive a bit longer. Same goes for battery because cpu temps affect the battery too.
You just need to test all the voltages yourself and see what works and what does not.
Always make a backup that if something goes wrong you can always restore the system.
Also if you undervolt dont go complaining to devs about crashing or system lockups.

i didn't know if it was going to be this difficult haha. i thought using the same settings should be okay since its a same chipset and all, but i think its worth a shot.
okay then i'll go straight to kernel adiutor and set my own voltages.
another question and sorry if its out of topic, im using twrp 2.8.7.0 at the moment, i can create backup but i can't restore the backup, the error mentions about locked systems or partitions, forgot the exact error code, any ideas?

You can chmod 755 or 775 the sd card in TWRP it could make things better????
Dont know for sure about that one though.
If i remember correctly you can use the chmod command in TWRP's fike manager.

Try flashing the BlackScreen kernel. My room temperature is about 35-38 °C and battery temperature is around 37-42 °C with medium to heavy usage. The temperatures you mentioned are normal IMO. Until they are below 43, it is fine.

Yeah. The phone heats up about the same temperatures for me too. With the stock Leeco EUI software, I had heating between 35-38 °C (battery temperature) so I consider it to be normal now. Actually I'm adapted to the temperatures on Nougat ROMs now.
But you "Block" the frequency of your cpu/gpu?
