[TIPS] This setup will make your beloved Mi3 run like a champ!

[rly]

Hello folks!

This thread is intended for sharing, please be kind. Any suggestions would be appreciated

A few days ago I was tired of having my Mi3 running on stock global dev MIUI 8, it was inefficient system with really bad memory management. On my experience, the MIUI tend to run out of memory. In some case, after a few hours of usage the system cannot reclaim the occupied RAM, thus making the system lags a lot and generate excessive heat!

Yes, MIUI is a feature-rich ROM, and the Mi ecosystem is a pretty mature ecosystem. However, those all greatness needs a lot of power to run on our 3 year old device. After a few research I decided to switch to CM13 ROM.

With efficiency in mind, I do my research and tinkering with my device to get the best setup possible without losing performance. The results are AMAZING! I can use my phone for a whole day without recharge in the mid day. All of this with huge improvement on performance, Real Racing 3 highest graphic setting without any noticeable lag! CPU and battery temperature are now significantly lower (43-47C idle / light tasks, 55-57C heavy gaming). Now that I've found the best setup, I want to share it with you folks! Here we go:

Mi3W 64GB
CM13 ROM snapshot build
CM kernel (automatically flashed while flashing CM13 zip through TWRP)
Screen resolution changed to 720x1280 use this guide
Modded interactive CPU governor (see screenshot below)
Undervolt (see screenshot below, this one really helps reduce CPU working temperature)
Noop I/O scheduler
Reduce aggresiveness of LMK (see screenshot below)

Thats all folks, hope this guide will get our Mi3 having another year of flagship-grade experience! Cheers! :highfive:

How did u undervolt

How did u undervolt

It depends on the kernel used. Cm kernel that he used supports undervolt. Careful when undervolting though as too much of it can cause cpu instability and reboots.

Yes, it depends on the kernel used. Some kernel support undervolting while others don't. You need to flash kernel that support undervolt.

While testing CPU voltage value, don't tick "apply on boot" option until you find the most stable voltage without causing system reboot or crashes. Every CPU has different limit on how far you can undervolt, but you can use the values on my screenshot as guidance (Snapdragon 801 / MSM8974-AB only)

Wow!! Thanks a lot bro. I'll fiddle now with my phone.

Random reboot after setting undervolt just likes yours

Undervolting (and clock adjustment, in general) pretty much is a case-per-case basis, so different handsets (even if it's the same type of device) may have different setup. Try lowering it first incrementally and test it, until you have it stable enough.

Ok thanks i will test it later
