Key Features to Consider
Selecting a custom kernel involves understanding its core components and how they impact your device’s performance and battery life. Two crucial areas to consider are the CPU governor and the I/O scheduler.The CPU governor controls how the CPU clocks speed up and slow down based on the workload. Different governors offer different trade-offs between performance and power consumption.
For instance, a performance-oriented governor like “performance” will prioritize speed, while a power-saving governor like “powersave” will prioritize battery life. Examples include Interactive, Conservative, and Ondemand governors. Experimentation is often key to finding the best governor for your usage patterns.The I/O scheduler manages how data is read from and written to your storage. Different schedulers can impact app loading times, system responsiveness, and overall performance.
Common examples include CFQ, Deadline, and noop. Again, the optimal scheduler often depends on individual usage and device characteristics.

Flashing a Kernel via TWRP, How to Install and Use Android Custom Kernels for Advanced Tweaks
First, you’ll need to download the kernel file for your specific device. Make sure it’s the correct version and compatible with your current ROM. This is a .zip file, usually named something like “kernel-name-device-version.zip”. Then, transfer this file to your phone’s internal storage or SD card. The exact location isn’t critical, as long as you know where it is.
- Step 1: Boot into TWRP Recovery. This usually involves powering off your phone and then holding a specific button combination (varies by device). You’ll see the TWRP logo on your screen once you’ve successfully booted into recovery. A screenshot would show the TWRP main menu, with options like “Install,” “Wipe,” “Backup,” etc. The background is usually dark, with text in a light color, often white or light gray.
The TWRP logo is usually prominent, often in the center or top of the screen.
- Step 2: Navigate to the Kernel File. In TWRP, tap on “Install.” You’ll then be presented with a file browser. Navigate to the location where you saved the kernel .zip file. A screenshot would show the file browser within TWRP, displaying the various folders and files on your device’s storage. The kernel .zip file would be highlighted or selected, indicating that it is the file that will be flashed.
- Step 3: Select and Swipe to Flash. Select the kernel .zip file. TWRP will show you a confirmation screen. Carefully review the file name to ensure it’s the correct one. Then, swipe to confirm the flash operation. A screenshot would show this confirmation screen, highlighting the swipe gesture required to initiate the flashing process.
A warning or caution message might be visible as well.
- Step 4: Reboot System. Once the flashing process is complete (you’ll see a progress bar and possibly some log messages), tap “Reboot System.” Your phone will reboot, and after a slightly longer boot time than usual (due to the new kernel), you should be back to your home screen. A screenshot would show the final screen in TWRP after a successful flash, giving the option to reboot.
Remember, if anything goes wrong, don’t panic. You can often fix bootloops by booting back into TWRP and performing a factory reset (though you’ll lose your data, so back up important files!). Always back up your data before attempting any major system modifications.
