Announcing Mint 12.5 Stable
3 min read
April 11th, 2023. I’m officially announcing the release of Mint 12.5 Stable.
Mint is a One UI-first custom kernel designed to bring optimized performance and battery life to Samsung Exynos 9610 devices. Mint Kernel has been the kernel of choice for many users as well as custom ROMs, being the default kernel on The Fresh Project's flagship Fresh.
The new Mint 12.5 Stable release introduces several improvements and new features. These include improved performance and stability, better battery life, and better compatibility with newer Android ROMs.
New on Mint 12.5
A Task Scheduler Straight From the Latest Galaxy
One of the major features of Mint 12.5 Stable is the introduction of a new scheduler based on the scheduler used on the latest Galaxy devices. This new scheduler is designed to improve performance and battery life even further, especially in scenarios where many apps are running at the same time.
Mint 12.5 also introduces Task EXpress (TEX) - a feature that prioritizes the app you have running, while keeping background apps on power-saving cores. With Task EXpress, you can enjoy a smoother and more responsive experience, while also extending your battery life.
TEX works by identifying the app that you are currently using and allocating more resources to it. This means that the app will run faster and more smoothly, without being slowed down by other apps running in the background. At the same time, background apps are moved to power-saving cores, where they consume less power and have minimal impact on performance.
A CPU Governor that Adapts to You
Mint 12.2 users have been testing a special version of the
schedutil governor that adapts to how you use your device to scale the CPU. With the release of Mint 12.5, this feature is now made official with the introduction of the
energy_adaptive CPU governor, codenamed AIGo. This innovative governor is specifically designed to optimize device performance and battery life based on your specific usage habits.
By forecasting your usage patterns and smoothly scaling the CPU frequency to avoid hitches or spikes, AIGo is able to provide a more responsive and efficient experience. With AIGo, you no longer have to constantly tweak settings to get the most out of your device. Instead, the governor learns your usage habits and automatically optimizes performance and battery life for you.
In addition, AIGo provides a smoother and more seamless experience by learning your device usage patterns. This ensures that hitches or spikes in CPU usage are avoided, resulting in a more consistent and reliable experience. Overall, AIGo offers a more intelligent and user-friendly way to optimize device performance and battery life.
AIGo is based on a Samsung patent from 2019, and has gotten its way to be used on certain Exynos and Qualcomm devices. Read the patent filing here.
