However, many users face difficulties when connecting a device to a smartphone for the first time - especially when it comes to budget Redmi models with simplified documentation. This article will help you understand all the nuances of synchronization via Bluetooth, including preparing devices, choosing the right application and solving typical errors.

Unlike the flagship Mi Watch, the Redmi series often requires additional steps to work steadily, such as manually activating the pairing mode or updating the firmware through Mi Fitness. We will look at the process for all current models (Redmi Watch 2/3/4, Redmi Watch Active), and also give recommendations for optimizing communication to minimize connection breaks. If you have already tried to connect, but the watch does not “see” the phone or vice versa, here you will find proven solutions.

One of the most common questions is which app to use to connect, with Xiaomi offering two official solutions:

For most users, Mi Fitness remains the best choice, but if you have Redmi Watch 3 or newer, it’s worth trying Zepp Life. Importantly, don’t install both apps at the same time, it can cause conflicts when synchronizing.

The official versions can be downloaded only from:

• 🌍 Google Play (Mi Fitness)
• 🌍 Google Play (Zepp Life)
• 📱 App Gallery for Huawei phones)

⚠️ Note: Do not download applications from third-party sources (APK-They often lack critical security updates, and some versions may contain malicious code masquerading as Mi Fitness.

3. Step-by-step instruction for connecting via Bluetooth

Now, let's move directly to the pairing process. Follow the instructions carefully, because even one step can be missed, and you can get a connection error.

1. Install and open Mi Fitness. When you first start up, the app will ask you to register or log in through Mi Account. If you don't have an account, create one (this is a must for data synchronization).

4. Notification setting and data synchronization

Once you’ve successfully connected, you need to configure what notifications will arrive on the watch and how often sync will occur. Open Mi Fitness, select your watch from the device list, and go to Notification Settings.

Here are the key parameters that should be set up immediately:

• 📱 Notifications from apps: Choose which messengers (WhatsApp, Telegram) and social networks will be duplicated for hours. Tip: disable unnecessary (for example, notifications from games) so as not to waste battery power.
• 🔔 Vibration and sound: Adjust the vibration intensity for different types of notifications. Redmi Watch 4 has a Smart Vibration feature that adapts to the noise level around you.
• 🔄 Autosynchronization: Turn on automatic synchronization of step, sleep and pulse data every 30 minutes to help avoid data loss when you’re in the middle of a clock.
• 🌙 Do Not Disturb: Set a schedule when the clock won't vibrate (e.g. at night) this saves charge and doesn't interfere with sleep.

For stable operation of notifications on the phone should be included:

• ✅ Auto-run Mi Fitness (Settings) → Annexes → Mi Fitness → Auto-start).
• ✅ Display notifications for messengers (Settings) → Notifications → Allow for each application).

If none of the solutions worked, try resetting the clock to factory settings:

1. On the clock, go to Settings → System → Reset settings.
2. Confirm the reset (may be required to enter) PIN-code, if it has been installed).
3. After restarting, repeat the connection process again.

Important: Reset will remove all data from the clock (steps, workouts, alarm settings), so pre-synchronize them with Mi Fitness!

6. Optimizing the clock to save charge

One of the main complaints about the Redmi Watch is that the battery is quickly discharged when used actively, and fortunately, most of the “gluttonous” features can be optimized without losing basic functionality.

Here are the key settings that should be changed:

• 🔋 Synchronization frequency: Set the interval no more than 1 time per hour (in Mi Fitness) → Settings of the device → Synchronization of data).
• 🌡️ Pulse monitoring: Turn off continuous measurement and leave only when exercising or every 30 minutes.
• 📶 Bluetooth Connection: In the watch settings, turn on the option to turn off Bluetooth in sleep mode (saves up to 20% charge).
• 🌙 Screenlighting: Reduce the backlight time to 5 seconds and turn off the Wrist Raise for activation.
• 🔔 Notifications: Leave only critical (calls, SMS, Messengers, disable notifications from games and social networks.

With these settings, the Redmi Watch 3 will last up to 10 days on a single charge (versus 5-7 days in standard mode).

Also, pay attention to the temperature: when using a watch in the cold (below -10 ° C) or in the heat (above +40 ° C), the battery goes down much faster, in such conditions it is better to wear the watch under clothing.

💡

The most voracious feature in Redmi Watch is constant heart rate monitoring, which can increase the operating time by 40-50% without significant loss of functionality.

4. Wait for the file to load (usually 5-15 MB weight).
5. Confirm the installation on the watch (you may need to press the button).
6. Do not disable Bluetooth or leave the application until the process is complete (takes 3-10 minutes).

If the update freezes:

• 🔄 Restart the clock and phone.
• 📱 Remove the watch from Mi Fitness and reconnect.
• 🌍 Check your internet connection (update downloaded via phone).

⚠️ Warning: After updating the firmware, all watch settings are reset to factory! Write down important data (such as alarm clock settings) in advance or sync it with Mi Fitness.

8. Alternative ways of connecting (without Mi Fitness)

If for some reason you can’t use Mi Fitness (like on a phone without Google Play), there are alternative ways to connect:

• 🌐 Through Zepp Life: As mentioned earlier, some Redmi Watch models are supported by this app. The functionality will be limited, but the basic features (stepmeter, pulse, notifications) will work.
