This guide walks you through how to factory reset M8 smart watch using both on-device and app-based methods. Whether you’re troubleshooting issues or preparing to sell your device, these clear instructions ensure a smooth reset process without data loss surprises.
Key Takeaways
- Backup your data first: A factory reset erases all personal info, apps, and settings—always back up fitness data, contacts, and preferences beforehand.
- Use the built-in reset option: Most M8 smart watches have a direct “Factory Reset” or “Restore Defaults” menu in Settings for the easiest method.
- Try the companion app if the watch is unresponsive: The official M8 app (or compatible fitness app like Zepp or Wearfit) can trigger a remote reset when the screen won’t respond.
- Charge your watch before resetting: Ensure at least 50% battery to avoid interruptions that could corrupt the system during the process.
- Re-pair after reset: Once reset, you’ll need to reconnect your M8 to your phone via Bluetooth and reconfigure notifications, watch faces, and health goals.
- Reset doesn’t fix hardware issues: If problems persist after a reset, the issue may be physical—contact customer support for repair options.
- Keep your firmware updated: Post-reset, check for software updates to ensure optimal performance and security.
Introduction: Why Factory Reset Your M8 Smart Watch?
So, your M8 smart watch has been acting up—freezing during workouts, draining battery too fast, or refusing to sync with your phone. Maybe you’re planning to sell it or give it to a family member. Whatever the reason, a factory reset can be the fresh start your device needs.
A factory reset restores your M8 smart watch to its original out-of-the-box state. It wipes all user data, installed apps, custom settings, and paired devices. Think of it like hitting the “refresh” button on your entire experience. While it sounds drastic, it’s often the most effective way to resolve persistent software glitches, improve performance, or prepare the watch for a new owner.
In this guide, we’ll walk you through multiple reliable methods to factory reset your M8 smart watch—whether you’re dealing with a responsive screen or a frozen device. You’ll also learn essential prep steps, what to expect afterward, and how to avoid common pitfalls. By the end, you’ll feel confident resetting your watch safely and efficiently.

Before diving into the reset process, take a few minutes to prepare. Skipping these steps could lead to lost data or a botched reset.
1. Back Up Your Data
Your M8 smart watch stores valuable information: step counts, heart rate logs, sleep patterns, workout history, and even custom watch faces. A factory reset deletes all of this. To avoid losing it forever, back up your data first.
Most M8 models sync with a companion app like Wearfit, Zepp, or the official M8 Health app (depending on your region and model). Open the app on your smartphone, ensure your watch is connected, and check if there’s a “Sync” or “Backup” option. Some apps automatically save data to the cloud, while others require manual export.
If your app doesn’t offer cloud backup, take screenshots of important stats or note down key metrics like total steps, average heart rate, or favorite workout routines. This way, you can re-enter them manually after the reset.
2. Charge Your Watch
Never start a factory reset with a low battery. The process can take 2–5 minutes, and if your watch dies mid-reset, it could corrupt the operating system—leaving you with a bricked device.
Aim for at least 50% battery, but 80% or higher is ideal. Plug in your charger and let it power up while you prepare your phone and notes. Most M8 watches use a magnetic charging cable that snaps onto the back—just make sure it’s seated properly.
3. Unpair from Your Phone (Optional but Recommended)
While not always necessary, unpairing your watch from your phone before resetting can prevent sync conflicts later. Go to your phone’s Bluetooth settings, find your M8 watch, and select “Forget This Device” or “Unpair.” This clears the connection from your phone’s side, so you can set it up fresh after the reset.
4. Note Down Important Settings
After a reset, you’ll need to reconfigure everything:
– Preferred watch face
– Notification preferences (which apps can send alerts)
– Do Not Disturb schedule
– Health goals (step target, sleep reminders, etc.)
– Alarm times
Jot these down in a notes app or on paper. It’ll save you time when setting up your watch again.
Method 1: Factory Reset via Watch Settings (Recommended)
This is the simplest and most reliable method if your M8 smart watch is responsive and you can navigate the menus.
Step 1: Access the Settings Menu
Wake up your watch by tapping the screen or pressing the side button. Swipe left or right to find the “Settings” icon—it usually looks like a gear or cogwheel. Tap to open it.
Step 2: Navigate to System or General Settings
Scroll through the settings list using the touchscreen or side button. Look for options like:
– “System”
– “General”
– “Device”
– “About”
Tap on the relevant section. On most M8 models, the reset option is nested under “System” or “General.”
Step 3: Find the Reset Option
Inside the system menu, look for:
– “Factory Reset”
– “Restore Defaults”
– “Reset to Factory Settings”
– “Wipe Data”
Tap on it. You may see a warning message explaining that all data will be erased. Read it carefully—this is your last chance to back out.
Step 4: Confirm the Reset
The watch will ask for confirmation. You might need to:
– Tap “Yes” or “Confirm”
– Enter a PIN (if you set one)
– Hold the side button for 3 seconds
Once confirmed, the screen will usually go black or display a loading animation. The reset process begins.
Step 5: Wait for Completion
The watch will restart automatically. This can take 1–3 minutes. You’ll see the M8 logo appear, followed by the initial setup screen (like when you first unboxed it).
Do not interrupt the process—don’t press buttons or remove the charger. Let it complete fully.
Step 6: Set Up Your Watch Again
Once restarted, follow the on-screen prompts:
– Select your language
– Connect to Wi-Fi (if supported)
– Pair with your phone via Bluetooth
– Log in to your health app account
– Restore preferences from your notes
Your M8 smart watch is now factory reset and ready to use.
Method 2: Factory Reset Using the Companion App
If your watch screen is frozen, unresponsive, or you can’t access settings, the companion app can often trigger a reset remotely.
Step 1: Open the M8 Companion App
Launch the app on your smartphone—common names include:
– Wearfit
– Zepp Life
– M8 Health
– Da Fit
Make sure your phone’s Bluetooth is on and the app is updated to the latest version.
Step 2: Connect to Your Watch
If the app shows your watch as “Connected,” great. If not, try refreshing the connection. Some apps have a “Reconnect” or “Sync Now” button.
If the watch is completely unresponsive, you may need to restart it first (hold the side button for 10–15 seconds until it reboots).
Step 3: Locate the Reset Option
In the app, go to:
– “Device” or “My Watch”
– “Settings” or “Advanced Settings”
– Look for “Factory Reset,” “Restore,” or “Reset Device”
Tap it. The app will send a command to the watch.
Step 4: Confirm and Wait
You’ll get a confirmation prompt on your phone. Tap “Yes” or “Reset.” The app will notify you when the command is sent.
Your watch should restart within 30–60 seconds. Watch for the M8 logo or vibration indicating a reboot.
Step 5: Reconnect and Set Up
Once the watch restarts, open the app again and follow the pairing process. You may need to scan for the device or enter a pairing code.
Method 3: Hard Reset Using Physical Buttons
If both the screen and app methods fail, a hard reset using the watch’s physical buttons might work. This method varies slightly by model, but here’s the general approach.
Step 1: Power Off the Watch
Hold the side button for 10–15 seconds until the screen turns off. If it doesn’t respond, wait for the battery to drain completely (not ideal, but sometimes necessary).
Step 2: Enter Recovery Mode
With the watch off, press and hold both the side button and the bottom button (if your model has one) simultaneously. Keep holding for 10–15 seconds.
You should see a recovery screen or the M8 logo appear. Release the buttons.
Step 3: Navigate to Reset Option
Use the side button to scroll through options like:
– “Reboot”
– “Factory Reset”
– “Wipe Data”
Select “Factory Reset” and confirm by holding the button or tapping the screen if it responds.
Step 4: Wait for Reboot
The watch will reset and restart. This method is less common but can revive a completely frozen device.
Troubleshooting Common Reset Issues
Even with careful steps, things can go wrong. Here’s how to handle common problems.
Watch Won’t Turn On After Reset
If your M8 smart watch stays black after a reset:
– Charge it for at least 30 minutes—sometimes the battery is too low to boot.
– Try the hard reset method again.
– Check the charging cable and port for damage.
– If nothing works, the battery or internal hardware may be faulty.
Reset Option Is Missing or Grayed Out
This can happen if:
– The watch is locked with a PIN you’ve forgotten. Try entering common defaults like 0000 or 1234.
– The firmware is outdated. Connect to the app and check for updates before resetting.
– The model doesn’t support on-device reset. Use the app method instead.
App Can’t Connect to Watch
If the companion app won’t pair:
– Restart both your phone and watch.
– Toggle Bluetooth off and on.
– Clear the app’s cache (go to phone Settings > Apps > [App Name] > Storage > Clear Cache).
– Reinstall the app if needed.
Data Still Appears After Reset
If your old settings or data remain:
– The reset may not have completed fully. Try the process again.
– Some apps restore data automatically from the cloud. Disable auto-sync in the app settings before resetting.
– Ensure you’re not logging back into the same account that backed up the data.
After the Reset: Setting Up Your M8 Smart Watch
Congratulations—your watch is reset! Now it’s time to make it yours again.
1. Pair with Your Phone
Open the companion app and follow the pairing instructions. You’ll likely need to:
– Enable Bluetooth
– Allow notifications
– Grant permissions for health data
Make sure your phone and watch are close together during this process.
2. Customize Your Watch Face
Browse the app’s watch face gallery or download new ones. Choose one that matches your style—minimalist, sporty, or with extra stats like weather and heart rate.
3. Reconfigure Notifications
Go to the app’s notification settings and select which apps can send alerts to your watch. Common choices include:
– Messages
– Calls
– Calendar
– Fitness apps
Avoid enabling too many—it can drain the battery.
4. Set Health and Fitness Goals
Re-enter your daily step target, sleep schedule, and workout reminders. If you backed up your data, you can estimate your previous goals.
5. Update Firmware
Check for software updates in the app. New firmware often includes bug fixes, battery improvements, and new features. Updating right after a reset ensures you start with the best version.
When to Avoid a Factory Reset
While powerful, a factory reset isn’t always the answer. Avoid it if:
– The issue is clearly hardware-related (e.g., cracked screen, non-responsive touch).
– You’re under warranty and the problem might be covered—contact support first.
– You haven’t backed up critical data and can’t risk losing it.
In these cases, try simpler fixes first: restarting the watch, updating the app, or cleaning the sensors.
