Franco Kernel Manager Franco Kernel Manager helps you evaluate Android performance and extend battery life. Check CPU temperature, GPU usage, and battery consumption with real-time analysis and customizable notifications.

Franco Kernel Manager

Measure device performance and help extend battery life on your Android phone with Franco Kernel Manager. Developed by Francisco Franco and widely used, it has already passed 100K installs and earned about 4.5 stars on Google Play—even though it’s typically listed as a paid app.

At its core, the app collects and displays key hardware and software information from your Android device. Grant it permission and it will read out the details it needs to show you. It also supports changing available options so you can tailor controls to your preferences. If you don’t want to pay around $1.49, you can download it for free using the APK link provided below.

Features

Intuitive interface

Franco Kernel Manager includes a set of advanced tools that are still easy to operate, making it simpler to manage your device’s components. The layout is designed so the most important options are always within reach.

You’ll also see major status cards in the notification shade, including items like CPU Temperature and Battery Consumption. You can control which notifications appear and what gets priority.

Get detailed analysis

The app provides accurate real-time monitoring for important system behavior, including battery usage, GPU usage, screen temperature, and more.

The Deep Analysis mode (exclusive to this app) is designed to detect even small changes while keeping battery drain low—so you can track indicators more effectively without stressing your device.

Custom tuning settings

One of the standout advantages is custom kernel tuning, which is especially useful for developers. It lets you adjust things like the IO scheduler, add custom tunables, and tune memory-related settings.

If you have technical knowledge, you can customize multiple options in just a few seconds.

Backup and restore

The app’s Backup & Restore feature lets you save your kernel configuration and recover it later if performance drops. Even though restoring is manual, the process is quick and typically takes only a few seconds.

Profile creation

Create separate profiles for different apps. For each app, you can define CPU behavior so gaming apps can run with one kind of settings while other apps use a more battery-friendly setup. This is a great way to boost gaming performance while also extending runtime when you don’t need maximum power.

Available Functions

• Custom kernel settings, including: IO scheduler, IO scheduler tuning, wakelocks, lowmemorykiller minfree, KSM, ZRAM, memory-related options, entropy, flar2 wake gestures, scheduler tuning—and the ability to add your own custom tunables.
• Per-app profiles so your frequently used apps can run under different rules. Example: use a higher CPU frequency for games and a lower one for reading. You can also toggle Wi‑Fi, enable/disable Android Battery Saver, set a specific Location Mode per app, and more.
• System Health with a clean UI showing real-time usage for: CPU/GPU/RAM/ZRAM, DDR bus, IO, thermal zones, and wakelocks. It also includes broad CPU frequency usage with support for clustered devices.
• Display and sound control: adjust RGB, saturation, hue, and contrast. Profiles are easy to set up with a user-friendly interface.
• Automatic Night Shift to warm your display with an orange/red tint for easier nighttime viewing.
• CPU temperature in the notification bar (for devices that provide CPU temperature export).
• Performance Profiles from FrancoKernel: Power-save, Balance, and Performance. Switch with one tap—no need to dig through settings. Includes a Home screen widget, launcher shortcuts, quick tiles, and automation support.
• Scripts manager to create your own shell scripts inside the app and pin them to Quick Tiles.
• Light and Dark themes compatible with Android™ 10.
• Backup & restore for the app’s own settings.

Tips

• Keep battery saver mode enabled for better battery longevity.
• Improve battery life using custom options such as Wake Gestures and a Battery Monitor.
• When gaming, set GPU frequencies to maximum to help graphics stay smooth and responsive.
• For heavy tasks and long sessions, monitor and adjust temperature to reduce the risk of overheating.
• Use Auto-Flash for regular updates.
• Before making major tuning changes, create a backup so you can restore your settings quickly.
