However, this comes with trade-offs. Aggressive CPU boosting can increase idle drain by 5–10% if the user does not tweak the governor parameters. Additionally, the custom thermal driver, while responsive, may allow the device to reach higher skin temperatures (up to 45°C) before throttling, which some users may find uncomfortable.
Benchmarking the Quicksilver kernel reveals significant improvements. In Geekbench 5, a stock Redmi Note 8 typically scores ~310 single-core and ~1,400 multi-core. With Quicksilver, the same device often reaches ~350 single-core and ~1,550 multi-core—a roughly 10–15% increase. More importantly, real-world performance is transformed. UI animations on custom ROMs become stutter-free; multitasking between Chrome, Spotify, and WhatsApp no longer forces background app reloads. Gaming frame rates stabilize: where the stock kernel drops to 25 FPS in heavy scenes, Quicksilver maintains a consistent 30–40 FPS. Quicksilver Kernel Redmi Note 8
Despite its benefits, Quicksilver is not for every user. Flashing a custom kernel voids the warranty and, if done incorrectly, can lead to boot loops. Some banking apps and Google Play Integrity checks may fail because the kernel modifies the proc/version signature. Furthermore, certain custom ROMs (e.g., those with KernelSU or Magisk patches) may conflict with Quicksilver’s own AnyKernel3 installer. Users are strongly advised to make a backup of their stock boot image before proceeding. However, this comes with trade-offs
The Quicksilver Kernel lives on Telegram groups and XDA-Developers forums. The developer maintains a CI/CD pipeline (often using GitHub Actions) to automatically compile new builds whenever the upstream Linux kernel receives a security patch (e.g., 4.14.118 → 4.14.336). This is crucial because the Redmi Note 8’s stock kernel stopped receiving updates after 2021. By backporting CVE patches, Quicksilver effectively extends the security lifespan of the device. Community feedback drives feature additions: for example, support for USB Fast Charging (forcing 900mA over USB instead of 500mA) was added after user requests. More importantly, real-world performance is transformed
In the ecosystem of Android custom development, the kernel serves as the lowest level of software abstraction, acting as the bridge between the operating system and the physical hardware. For a device like the Xiaomi Redmi Note 8 (codenamed Ginkgo ), which shipped in 2019 with the modest Qualcomm Snapdragon 665, the stock kernel provided by Xiaomi is often conservative—prioritizing thermal stability and battery longevity over raw performance. Enter the : a third-party, open-source custom kernel designed to replace the stock Linux-based kernel. For enthusiasts seeking to unlock the true potential of the Snapdragon 665, Quicksilver represents a sophisticated balance of aggressive tweaks, advanced power management, and hardware optimization. This essay explores the architecture, key features, performance impact, and community significance of the Quicksilver Kernel for the Redmi Note 8.
