As you know Kirin 950/955 chipsets have "ROG Power Saving Mode". It decreases your phone screen resolution to 1280*720 for battery saving. I am wondering if it's possible to integrate to Honor 7(Marshmallow). Maybe by using kernel or .prop files?
If it needs a new generation chipset, it's understandable. But if it's not, I hope we can find a way to have this feature.

P.S. Even Ascend P7 has it.....

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.
Hi guys, i'm a newbie, i need the help of experts, i have a star n9589 with a MTK6589 and i'm searching for a program to undervolt my phone, in the store there are several programs to do it but seems that no one support it if not for the clock of the cpu, but other voltages are no supported, so can someone tell me if exist a program that support it? the reason is because my battery drain is excessive, pratically in standby it's draining exactly as in a phone call, and after 13 hours of standby it's over, i tried every possible way deactivating applications, wireless optimization etc,,, but no way that is a standby killer, untill i read that the only things that really affect the battery are the kernel, the voltages and the LTE, trying antutu cpu master helped me a lot saving battery optimizing the cpu clock when in standby, so i think that lowering the voltage in a reasonable way that my phone still keep it stable could solve it, someone know if there is a software that does it in MTK6589 processors? Thx all in advance!
The few "real world" reviews that are popping up show very little battery life differences between the S21 and S20 in web surfing which is similar activity to what I perform.
Surprised given the 5nm S888 and efficiency improvements with the 5G modem. Also has same size battery.
Are people hearing different?
Chris
You are correct. Likely a combination of (1) S888 design is not very power efficient and (2) samsung 5nm euv < tsmc.
The power savings from the variable refresh rate screen, integrated 5g modem and 4gb ram reduction appear to be just *barely* enough to make up for the inefficiency of the s888.

Hi, if you can enjoy putting this on your phone you Will be glad to have freely more autonomy on your phone, also, less heat that you will see in the same moment that you apply it, and, what is better, you will be able to have a lot more battery Avoiding being dependent of the charging and you can use your very well "heat efficient" phone with their polymer case which made a "sandwich" having it the cpu backed every time that a girl text you on tinder or stuff or, you put on a game to play.
What it does :
- Tweaks the Cpu to have less heat as well as more performance, enables You to choose what's better for you, in four options.
WHY I need this:
Apple have their iphone with 6 cores instead of 8. Their cores are: "two cortex X2 rebranded" and four low energy cores. And, they use only one program (iOS) and above them they run "complements" of the program, called "apps". Based on this, you can have FOUR different browsers on your iOS device that are essentially the same (WebKit) with a skin and some functionality. Avoiding you to have options. Likely better than that. So, you don't need power. Because you are not using it. Since everything runs fast because it's pre-loaded with this iOS, android developers paid by companies put a lot of cpu and Gpu power on your android phone to OVERPOWER that iOS devices. And that, comes at cost of battery.
So, in order to have the same functionality as before, and the same power level of apple, when you cut down the power of s processor you will have the same app opening/closing speed of apps as well as functions but, with a lot of more battery. Maybe you see one of tho "stutters" but that aren't granted, and you will have less heat also.
So, this module created by @yc9959 works very well letting you choose from four options to fine tweak your cpu. Install should be through magisk.
【Preset Performance Mode】
Caton powersave: Large performance limit, suitable for users who do not require high fluency
Balanced balance: Moderate performance limit, suitable for daily mobile phone
Power consumption performance: approximately equal to no performance limit, suitable for tablet daily life
Extremely fast: similar to the cost of electricity, with continuous performance output, suitable for mobile gaming
【Sub-module description】
SfAnalysis: Recommended, reduces dropped frames at the cost of lower power consumption
SsAnalysis: optional, try it if you experience dropped frames in desktop animations

Greetings to the Devs.
Does anyone try it?
Waiting for feedback before I try
I downloaded and installed it but the presets commands are not well explained, I'm trying to understand

I come back here to say that I found it, I had to open the .json to find it, since the creator doesn't say..
The presets are:
Balance
Powersave
Performance
Fast
You can change the values too, inside .json
anyone used this? does it really work?
I was gaming on my OnePlus device and suddenly I notice that the CPU usage is 100% and the GPU usage stays below 15% always. You can check it in the image below. This happens even in OnePlus 11. Framedrops occur every once in a while due to this. What's the advantage of having a GPU so powerful if the games don't even utilise it? Does anyone know how to solve this without root?
