Download The Best Custom Kernel For Xiaomi Mi 8 Lite

Xiaomi Mi 8 Lite has got an excellent response from the consumers as well as a good community that has been built on XDA, where the developers are taking the initiative to build custom ROMS. Now you can also download the best custom kernel for Xiaomi Mi 8 Lite to enhance your device and make it more powerful.

As of now, there are two custom Kernels available for Xiaomi Mi 8 Lite that can be used with MIUI and AOSP based custom ROM. All these custom Kernels can be flashed on any ROM, which is running on Android 9 Pie. You may also consider to flash Android 10 custom ROM and test the following kernels and report it to us in the comments section. Do not forget to take the backup of your current kernel.

What Is a Kernel?

Android devices use the Linux kernel; every phone utilizes their variant of it. Linux kernel maintainers keep everything tidy and accessible, contributors (such as Google) include or change things to meet their demands, and the people creating the hardware contribute too since they need to come up with hardware drivers to the parts they’re using for your kernel version they are using. This is the reason why independent Android programmers and hackers take time to vent new releases to older devices and get everything working.

Drivers are written to utilize one version of the kernel for a phone that might not work with another version of applications, which is important because the kernel’s primary functions are to control the hardware. It is a great deal of source code, using many more options while constructing it than you can imagine, but ultimately it is only the intermediary between the hardware and the software.

It sounds complicated, and it’s. Nevertheless, it’s also pretty standard computer logic, there’s an act of any kind generated for every single event, and based on that action, things happen to the running applications. With no kernel to take and send info, programmers would have to write code for every event for every single piece of hardware inside your apparatus. The kernel helps communicate with it through the Android program APIs, and hardware developers only need to produce the device hardware communicate with the kernel.

Advantages and Disadvantages of Custom Kernel


  • A custom kernel can provide extra features and configurations.
  • Developers can add new features from other smartphones kernels that do not exist for your device.
  • It helps you maintain the CPU power and lets you save the battery life.
  • You can configure the I/O scheduler that is used and lots of other stuff.
  • You have the ability to control the maximum and minimum frequencies of the CPU that can scale up or down using a kernel auditor.


  • If you are not careful enough while using the custom kernel, you can end up harming your device to the extent of bricking it.

Custom Kernel For Xiaomi Mi 8 Lite

There are two custom kernels for Xiaomi Mi 8 Lite (Platina) as of now under ongoing development. The custom kernels we are talking about are Acrux Kernel and Fera Kernel that support both stock MIUI and any AOSP based custom ROM running on Android Pie 9.

Acrux Kernel

Acrux Kernel V4.4 ALS based is imported cleanly from Xiaomi, EAS kernel with HMP packs removed, and has been updated to the latest CAG. The custom kernel is also upstreamed with the mainline Linux, which aims to provide a balance of performance and battery backup.

  • Debug kernel and debug fs gone


The link for the download contains previous builds as well directly from the developer nysadev from XDA. Try to figure out the latest version by sorting the upload date or by checking the date stamp on the kernel.
