What’s New in This Update?
This release includes several low-level kernel improvements designed to improve both performance and efficiency.
Improved Memory Management
The kernel introduces optimizations to memory allocation and management, helping applications remain responsive while improving multitasking performance during heavy workloads.
Better Scheduler Balancing
Scheduler improvements allow CPU resources to be distributed more efficiently between running tasks, resulting in smoother animations, faster app switching, and improved system responsiveness.
Locking Mechanism Optimizations
Several internal locking mechanisms have been refined to reduce unnecessary overhead, improving system stability and reducing latency during intensive operations.
Enhanced I/O Accounting
Storage-related optimizations improve input/output handling, helping applications load more quickly and providing a smoother overall user experience.
Compression Handling Improvements
The kernel includes updates to compression-related components, which can improve memory efficiency and reduce system overhead under demanding conditions.
Display Subsystem Cleanup
Internal display subsystem improvements help provide more stable graphics rendering while reducing unnecessary processing.
Optimized String Operations
Low-level string operation enhancements contribute to improved system efficiency by optimizing frequently executed kernel functions.
Charging Features
One of the standout features of JoKernel is its built-in charging options.
Bypass Charging
The kernel supports bypass charging, allowing compatible devices to draw power directly from the charger instead of continuously charging the battery during supported scenarios. This can help reduce battery heat during extended gaming sessions.
Fast Charging Modes
Fast charging functionality is also supported, enabling compatible charging configurations for quicker battery replenishment.
BPF and Non-BPF Versions
JoKernel is available in both:
BPF Version
Non-BPF Version
This allows users to select the version that best matches their ROM and system configuration.
KernelSU Support
The latest release supports both major KernelSU implementations:
KernelSU Next (KSU Next)
RKSU
This makes the kernel suitable for users who require modern root management solutions.
Battery and CPU Options
JoKernel offers multiple configuration options to suit different hardware modifications and performance preferences.
Battery Profiles
Users can choose between:
Stock Battery (STK)
5000mAh Battery (5K)
CPU Profiles
Two CPU configurations are available:
Performance CPU (PERF) – Prioritizes maximum performance.
Efficient CPU (EFF) – Focuses on better battery life and lower power consumption.
ROM Compatibility
The kernel supports multiple ROM types, including:
AOSP ROMs
MIUI ROMs
HyperOS ROMs
This broad compatibility allows users to switch ROMs without changing to a completely different kernel.
Installation Options
JoKernel provides flexible installation methods.
Users can either:
Rename the ZIP file according to the desired configuration before flashing, or
Leave the filename unchanged and choose the preferred options during the installation process.
Available combinations include:
AOSP + Stock Battery + Performance CPU
AOSP + Stock Battery + Efficient CPU
AOSP + 5000mAh Battery + Performance CPU
AOSP + 5000mAh Battery + Efficient CPU
MIUI/HyperOS + Stock Battery + Performance CPU
MIUI/HyperOS + Stock Battery + Efficient CPU
MIUI/HyperOS + 5000mAh Battery + Performance CPU
MIUI/HyperOS + 5000mAh Battery + Efficient CPU
This flexibility allows users to tailor the kernel to their specific device configuration.
