I'm not sure why but this kernel solved charging rate during screen on / using device.

Stock kernel giving me 2k mA +-

Omega kernel giving me 6k mA +-

Thanks 👍

I was using this kernel (May 5 update) briefly before updating to Can the same kernel be flashed on the latest update? Or does it even matter which version of OOS I am on?

    If someone has encountered a double-click problem, check if you have an enabled magic module called oneplus9poos. Disabling this module solved the problem.
    And after installing OOS I have to first install Magisk into inactive slot, before rebooting the device, right?
    You can uninstall Magisk from the Magisk app, as Update needs stock kernel. Download update from Oxygen Updater app and install from Settings/ update from local storage. Do not reboot, then Install Magisk to Inactive Slot. Now you can reboot. Then use kernel manager to flash Kernel.
    Not true. I never uninstall magisk and I install OOS updates over omega kernel.
    Yes when updating using a FULL OTA. When was the last time a FULL OTA was on time and not a month or two late. You can not take an incremental update on Omega or any custom kernel. It will fail.
    Latest release on op9 global. Not getting any Gmail's . Well I do but in loads and days later. Not right away. First time I've experienced this.
    You can update to OOS first than update the kernel.
    After installing the OOS you'll have to install kernel once again.

    Hello everyone, this is my personal kernel for the OnePlus 9 Pro.
    My philosophy on the kernel is pretty simple, intended to replace the stock kernel, but with a lot of under-the-hood tweaks.

    Hopefully you will all enjoy!

    Important thread information!

    I refuse to acknowledge/respond to bug reports that do not include clear steps to reproduce, a logcat, and a console ramoops (if random rebooting) or a dmesg (any other issues). Follow this guide to do this.
    Keep things civil, no flaming in the forums!


    • Up to date with OxygenOS 11 source
    • Compiled with Google's Clang toolchain for maximum stability, with all warnings and errors fixed
    • Compiled with Clang's cortex-a55 optimizations
    • Many tweaks under the hood for smoother UX, lower battery drain, etc.
    • Westwood as the default congestion algorithm (BBR is also available)
    • Available to flash with AnyKernel3

    Thanks where it's due

    @pyry666 for all his help getting me logs after logs after logs. Without him this wouldn't have been possible!
    @Burt Squirtz and @crashazz3 and @TheKnux for helping to test
    Kerneltoast for his extreme patience and guidance
    osm0sis (for AnyKernel3)
    @eng.stk for finding a way to have proper hardware detection working
    New kernel release!

    - Pulled in patch from Google to make cpufreq stat collection less CPU-hungry (smoothness)
    - Pulled in 3 Clang/LLVM stability fixes from upstream Linux
    - Pulled in a patch for better power consumption when vibrations are enabled (from arter's source)

    While this kernel works on latest, please note that OnePlus hasn't released sources yet for

    New release!

    - Build with Google's Clang 13.0.1, updated Binutils to 2.37
    - Pulled in 5 code fixes from CAF for display driver
    - Pulled in 2 logic fixes from CAF for display driver
    - Pulled in 3 various CAF stability fixes
    - Fixed a dmesg error message with a commit from upstream Linux
    - Removed all android_fs tracing from the ext4 and f2fs filesystem drivers
    New kernel release!

    This is a huge one in terms of stability and smoothness.

    - GCC LTO implemented
    - GCC O3 optimization (together with LTO results in significant improvement of hackbench scores)
    - Wireguard added
    - Anykernel 3 updated
    - Critical and stability fixes from CAF
    - More code fixes based on GCC's diagnostics
    - Significant improvement to ZRAM speed

    New kernel release!

    The test team has been crazy busy, flashing sometimes 5 builds a day to pressure test, and come up with this new kernel.
    After tons of performance tests, we found that Clang (with the included optimizations) outperforms even the best GCC builds, so I'm now moving to using Clang by Google to compile the kernel.

    - Fixed major network error where userspace was trying to modify network settings but the kernel wasn't allowing it (this issue is also present on stock kernel)
    - Pulled in a fix from CAF to improve/lower battery drain
    - Updated Wireguard module to latest version
    - Built using Google's latest Clang (12.0.6)
    - Enabled all Clang internal optimizations (reverted a crazy CAF patch disabling them), and fixed all subsequent code errors
    - Fixed an IRQ saving issue found via lockdep (upstream)
