I have the Xperia Z1 compact, which has a 4 core processor. If I use Kernel Auditor to limit usage to 1 core only, would this improve battery life or make it worse?

what's the differnce btw. OC vs non OC ? thanks

Overclocking is to increase your processors clock speed. The processor comes with a fixed clock speed which is mentioned in it's specs (1 GHz, 1.5GHz etc). OCing is to increase this speed past the fixed or 'stock' value to achieve better performance from the phone. Generally, if a phone has a fast enough processor out of the box, you won't notice much of a difference OCing. The main performance gain will be seen in benchmark tests. But if you have a slow processor, it'll make a difference to usability. Since more processing power = more electrical power, it causes greater battery drain and also reduces the life of the processor in the long run, because it heats up more and there's no cooling apparatus in a phone unlike a computer. A little OCing is fine, but overdoing it continuously will damage your processor. My phone is rated for 1 GHz but OCed to 1.15 GHz. It can go uptown 2 GHz max, but like I said, not good. OCing depends on the kernel of the phone. Stock kernels do not support it, but almost every custom kernel supports it. A non OCed device is one which is running at the stock frequency designated for it.
Sent from my Desire HD using xda premium
with OC, ur processor xtra hard working. ur hh rapidly heat, battery drain faster...
so don't do it if u only using hh for simple app (except u want play HD's Games)
sorry for my bad english...
I would like to know if it is safe to change the max cpu lock from quad core to single core mode when in need of battery or even other modes? How about for daily use but still needed battery life?

you can find more information about this in Siyah's Kernel thread.
I locked mine to 2 cores. After researching about turning off cores, it's mentioned that it's best to just leave all 4 cores on and let android manage the power. I will turn all 4 cores on later because i'm testing dual core mode for personal reference but it maybe void because i've under volted my cpu along with turning off the 2 cores. So far my battery is draining less and i'm using my phone more this morning. I don't even notice a performance drop. My phone is still smooth..but then again i do not use my phone to play games that require a lot of performance.
Thanks for your response. I'm now testing my s3 in a single core mode and battery draining is less also. For the performance I can say that it is not bad. However, what I'm afraid of it is if has bad effect on the cpu itself.
Some Guy Who Can Answer me What is Best in Terms of Energy Expenditure
Ex: I have a processor 3Ghz and confine it to Work for in the Maximum 1Ghz, He Will Handle All Using a Greater Processing Time and Less Energy in Lower Speed
Or leave Him With 3Ghz and He will use the Clock Max and Greater Energy and low Processing Time
Which is better in terms of energy expenditure?
Hey there, I have M4 Aqua freshly rooted. I changed the Governor in SetCPU to Performance on CPU and set it up to max frequencies on the 4 big Cores (1495MHz Min./Max.) and the 4 LITTLE cores (1113MHz Min./Max.). The CPU is Qualcomm Snapdragon 615 MSM8939. But the problem is that when I launch any CPU demanding program or game, the phone only uses the power-saving 4 LITTLE cores. Is there any way to lock the whole device only to the 4 powerful big Cores or to just adjust them to be active when in program/game?
Thanks alot for asnwering, I would be really happy with any solution.
Use Kernel Auditor to set the LITTLE cores and BIG cores to performance. The kernel that the M4 currently has is poorly optimized for handling tasks across it's 8 cores, so this is a temporary fix until it's (hopefully) updated.
The soc is the problem, even the moto x play have similar problems with performance
I have a script for disabling and locking 4 small cores, and performance is way better i will try to make it flashable zip and upload here

Does disabling the small cores affect the max performance much?

I tried to disable the small LITTLE cores today but the performance was decreased by at least 10% and the temperatures are still the same after 15-20 mins. of gaming - 70-80°C which lags the device.

Funny enough, I'm experiencing massive performance (in terms of smoothness and responsiveness) after disabling all 4 LITTLE cores. Use the OnDemand Governor for the big cores.
Still not working, it's probably the phone's problem. I mean the overheating, it's still around 70-80°C when gaming, the games and programs stutter.
Hi.
Would the Xperia X be faster than the Xperia Z5?
As when I ran a benchmark on my Z5, it had thermal throttling so the score went down to approx. 70,000.
So then I put it on a ice block and I got a score of 103,000 on antutu. (The CPU and GPU scores went down when it was thermal throttling, and the others had stayed the same)
So, that had me wondering if a Xperia X that was not thermal throttling would be faster than my Xperia Z5 that was thermal throttling.
What do you think? Should I keep the hot Z5 or get a cool Xperia X?
Many thanks

The difference between them is pretty small, but SD810 is a flagship SoC, while SD650 is a midrange one. On the other hand, X is supported by SODP, and with the release of k4.9 it'll be even faster than before. So, you can choose Z5 if you don't care about custom ROMs and such OR you can take X and be happy with a slightly slower SoC but much more potential.

from the angle of hardware z5 is always better !
