When your POCO F6 starts rebooting on its own, it can feel like you're fighting with your own phone. This is a common issue with Android devices, often tied to a misbehaving app, a software bug, or even a hardware quirk. The good news is you can usually fix it yourself without a trip to a service center.
Before you start, it's a good idea to back up anything important. You can use Google Drive or Xiaomi's cloud service to save your photos and files. This keeps your data safe in case you need to do a more drastic reset later on.
Force Restart Your POCO F6
This is almost always the first thing to try. A force restart clears the phone's temporary memory and can stop a minor software glitch that's causing the loop. For the POCO F6, it's very straightforward.
Just press and hold the power button on the right side of the phone. Keep holding it for about 15 to 20 seconds, until you see the POCO or Xiaomi logo appear on the screen. This forces a clean boot and often resolves a random restart cycle immediately.
Check for a Problematic App
Third-party apps are the most frequent cause of random reboots on Android. If the restarts started after you installed a new game or utility, that app is the prime suspect. Start by booting your phone into Safe Mode.
To enter Safe Mode on the POCO F6, press and hold the power button until the power menu appears. Then, tap and hold the "Power off" option on your screen. A prompt will ask if you want to reboot to Safe Mode, tap OK. If the phone runs fine in Safe Mode, you've confirmed a third-party app is the culprit.
From there, you'll need to find the bad app. Think about what you installed recently. Uninstall those apps one by one, restarting normally after each removal to see if the problem stops. Pay special attention to battery savers, custom launchers, or any app that requests deep system permissions.
Update Your Apps and HyperOS
Outdated software is a breeding ground for bugs that can cause system instability. First, update all your apps through the Google Play Store. Open the Play Store, tap your profile icon, and go to Manage apps & device. Under "Updates available," tap Update all.
Next, check for a system update. Xiaomi and POCO regularly release updates to fix known issues. Go to Settings > About phone > HyperOS version. Tap the "Check for updates" button and install anything that's available. An update in 2025 or 2026 might specifically address reboot problems on the F6.
Clear App Cache and Data
Sometimes an app's stored data gets corrupted. This doesn't delete your login or saved files from the cloud, but it clears the temporary junk that can cause crashes. Go to Settings > Apps > Manage apps.
Find the app you suspect (or start with system apps like "Android System" or "Google Play services"). Tap on it, then go to Storage usage. Tap Clear cache first. If the problem continues, you can try Clear data, but know this will reset the app to its freshly installed state.
Check for Overheating and Manage Performance
The POCO F6's Snapdragon 8s Gen 3 chip is powerful, but it can get warm during heavy gaming or video recording. If the phone gets too hot, it will throttle performance or even restart to protect itself. Feel the back of the phone. Is it unusually hot?
If overheating is the trigger, give the phone a break. Remove its case to help it cool down. Avoid using it while it's charging with the 90W brick, as that generates significant heat. For long gaming sessions, consider lowering the graphics settings in your games to reduce the load on the processor.
Free Up Storage Space
When your phone's storage is critically full, the operating system doesn't have room to work properly, which can lead to crashes and reboots. Go to Settings > About phone > Storage to see how much space you have left.
If you're below 10% free space, it's time to clean up. Delete old downloads, offload photos and videos to Google Photos, and uninstall apps you no longer use. The POCO F6 doesn't have expandable storage, so managing internal space is key.
Disable Battery Protection and Check Charger
While features like Battery Protection are great for long-term health, they can sometimes interact oddly with the power management system. Try turning it off temporarily to see if it stabilizes the phone. Go to Settings > Battery and look for the battery protection or charging optimization settings.
Also, try a different charging cable and power adapter. Even though you have the included 90W charger, a faulty cable can cause power delivery issues that might confuse the phone and cause a reboot. Try charging with a standard, lower-wattage USB-C charger for a while to test.
Reset All Settings
This is a more thorough step that won't delete your personal data like photos or messages, but it will reset all your system settings to default. Things like Wi-Fi passwords, Bluetooth pairings, and display preferences will be lost.
To do this, go to Settings > About phone > Factory reset. Then, select Reset all settings. Enter your PIN or password if prompted. This can fix issues caused by a deep-seated configuration error.
Perform a Factory Reset
If nothing else has worked, a factory reset is the final software step. This will erase everything on your phone and return it to its out-of-the-box state. Please ensure you have a complete backup before proceeding.
You can do this from within the settings menu if the phone is stable enough: go to Settings > About phone > Factory reset > Erase all data. If the phone is stuck in a reboot loop, you can use the hardware keys. Power off the phone, then press and hold the Volume Up button and the Power button together until the Mi Recovery screen appears. Use the volume keys to navigate to "Wipe Data" and select it with the power button.
After the reset, set up the phone as new without restoring a backup immediately. If the reboots stop, you know it was a software issue. If they continue even on a fresh system, the problem is likely hardware-related, such as a faulty power button, loose internal connection, or a failing battery, and would require professional service.
