Description

The Xiaomi Watch S4 stands out with an interchangeable bezel, premium design, and a high-brightness AMOLED display. With HyperOS 2, GPS, Bluetooth calling, 150+ sports modes, and up to 15 days of battery life, it is the ultimate smartwatch for any occasion.

What's New with the Xiaomi Watch S3

  • The brightness of the Watch S4's display is significantly improved, reaching up to 1500 nits compared to the Watch S3's 600 nits, enhancing visibility in bright environments.
  • The Watch S3 uses two level buttons for navigation, while the Watch S4 replaces one button with a rotating crown, offering a more intuitive and smoother scrolling experience through the menus.
  • The Watch S4 is upgraded to Bluetooth 5.3 from the Watch S3's Bluetooth 5.2, providing more stable and efficient connections with lower battery consumption.

See here for a comparison of the features of the two models.

Why choose it

  • Interchangeable Bezel (Bezel Design): This is its "magical" feature. You don’t just change the strap, but the entire bezel around the screen. As soon as you snap on a new bezel, the watch automatically recognizes it and changes the watch face to perfectly match your new style!
  • 1.32" AMOLED Display with 1500 nits: The 2026 display is brighter than ever. The colors "pop" out of the crystal, and using it under the intense Greek sun is now a pleasure, not a challenge.
  • HyperOS 2.0: Xiaomi’s new operating system makes the watch fly. The connection with your phone (especially if you have a Xiaomi) is instantaneous, and notifications now arrive more cleverly organized than ever before.

Health & Technology

  • 98.5% Accuracy in Heart Rate: With the new sensor, measurements approach the accuracy of medical chest bands.
  • Dual-Band GNSS (5 Systems): For those who run in the city, GPS locks in seconds and doesn't lose your route among tall buildings.
  • AI Sleep Tracking: Provides you with a complete analysis of your sleep quality and suggests ways to wake up with more energy.

Battery: Forget the Charger

  • 8 Days Battery Life: With typical use, the Watch S4 lasts for 8 days.
  • Fast Charging: 5 minutes of charging is enough for 2 full days of use.


Smart Functions that Make Life Easier

  • Bluetooth Calling: Crystal clear call sound thanks to the upgraded microphone with noise cancellation.
  • NFC Payments: Pay for your coffee simply by bringing your watch close to the POS (via Xiaomi Pay).
  • Gesture Control: You can perform certain functions (such as rejecting a call) just by moving your wrist.

Owner of this particular smartwatch for 3 months now, always on my wrist, so it has been tested quite a bit and I can give a full review. It was purchased for about €145.
During the time I've had it, it hasn't given me any glitches or problems.
Personally, I consider it a very beautiful watch whose design and build give you a premium feel. It's also nice that you can change the crown and, combined with another strap as well as the many watch faces available in the app, from one moment to the next, you feel like you're wearing a different watch. The strap it comes with is completely uncomfortable, so it was changed immediately.
Its screen is very good, clear with good resolution and brightness, and responds instantly.
Its measurements are relatively good. The heart rate readings are accurate. In oxygen and step measurements, there are some deviations. It measures distance well, as well as sleep duration (it even records short naps).
Notifications come through normally, depending on what you have set to show. For those wondering, you cannot reply to messages via the watch. You can answer calls normally.
Disconnections with Poco X3 phone, I have not noticed. The contactless payments with NFC have been incredibly convenient for me, which I consider a big plus. It works seamlessly with National Bank's Mastercard debit and credit cards.
The battery does not last 2 weeks as stated. With measurements enabled in smart mode and the screen activating with wrist movement, it lasts about 6-7 days. With the screen off and measurements enabled, it gave me about 3 extra days. Now, if you have everything off, then yes, it can last 2 weeks, but what's the point?
The speaker and microphone of the watch are ok. It sounds good on calls, but I would have preferred the speaker to be a bit louder with volume adjustment. In a quiet place, you will be heard and mainly you will hear just fine. With a little noise, there is an issue. Since some mention waterproofing, in the shower where I use it, there is no problem. In a pool/sea, I haven't tried it and I don't know if I would trust it.
The Mi Fitness app runs and syncs just fine.
In conclusion and overall, I think it is worth it and is a very honest watch for its price and what it offers.
If a couple of little things were fixed, it would be the ultimate value for money, so 4.5/5*

DO NOT PUT IT IN WATER. Despite the fact that it claims to function in water, after using it in a pool it started showing some weird things on its screen and after a while I noticed that even with zero usage, its battery barely lasts 12 hours. Now I'm dealing with the warranty supposedly for repair, but it's not great having to pay 20 euros for shipping, which the warranty does not cover.

Edit 25/10/25. After the "service" I was informed that the watch was completely replaced, so the problem is probably known and they just brushed it off, otherwise they would have just replaced a component.

    Very beautiful and elegant watch. The 41mm size is ideal for a woman's wrist and the Mint Green color is even more beautiful up close. The screen is bright, the battery lasts long, and the health and fitness functions are especially useful. So far, I am very satisfied with my purchase.

    I have had it for 6 months. I only changed the bracelet and put on a metal one and it looks much nicer. The watch is awesome, it hasn't shown any lag or defect. I use it with very intense sweating and I don't take it off when I shower. It hasn't shown any problem.

    This review is about case size: 47 mm, colour: Black

    Owner of Apple Watch and HUAWEI Fit 4 pro, I have to say that this particular one is quite "poorer." Of course, the price is also quite low, but it remains basic.
    Don't expect advanced features or other goodies. Here, things are simple, and in general, it stays at the essentials.
    Measurements are relatively accurate and good build quality are positives. The battery is also good, but nothing special... If you activate all the functions (which are not that many), the battery in my hands lasts 4-5 days. Much better than an Apple Watch, but behind the (much more advanced) fit 4 pro.
    A big minus is the charger, which is the classic one with pins and not wireless.

    This review is about case size: 47 mm, colour: Black

    Beautiful design, many functions.
    The battery life depends on the functions that are enabled and the programs the user uses.
    I have notifications enabled from specific mobile apps, the walking and calorie functions, I don't answer calls with the watch, I don't have NFC enabled, I chose a low-power face and I haven't used any sports program. The battery life ranges from 12 to 14 days.
    At some point I answered a call and noticed that the speaker volume is low... In general, you need to have the watch close to your face to hear and be heard.
    Finally, I didn't try it in water to avoid possible problems... "I take precautions just in case!" :-)

    Beautiful watch but to pay with NFC you need to have cards from specific banks and they must be exclusively MasterCard. Also, in the two days I've been wearing it, the "ring" around the watch got lost, which comes off very easily, at least on mine.

    Very good build quality. Easy to use. Beautiful UI. Great integration with iPhone 14. Not very accurate in its measurements (e.g. shows 37.1 temperature instead of 36.6). Finally, I would like the ability to install simple apps on the watch (some light games, AI tools, communication provider apps, etc.).

    Very nice little watch and very light, I didn't expect to wear it even when I sleep. The screen is bright and with good response. The strap is very comfortable, you forget you are wearing it.
    The only negative is that it has a charging base and it is not wireless so you can put it on your phone's base.
    For my wrist, the 41mm is just right. The 47mm is a monster.

    I like it as a smartwatch, good battery life and nice appearance. I feel it comfortable on my wrist. Decent measurements and no connection problems with a Xiaomi phone. However, I had a strange problem and now it is in for service: during the night sleep I turn off the bluetooth on the watch, it locked itself with a pin... because bluetooth is off it can't be unlocked from the phone and a hard reset can't be done, since there is no such option in locked mode. So I am waiting.

    This review is about the colour: Gold

    The battery barely lasts 2 days. The measurements have discrepancies. Music cannot play independently... if you want that, you have to download songs directly to the watch, but there isn't enough storage. And generally, you always have to have your phone next to you for anything. NFC is easy to activate. Overall, it's only worth it for the gold bracelet. Did I regret it? Yes, I regret it. €188 is overpriced... no value for money at all!

    very good watch, it has been very convenient for me but the only disadvantage is that they haven't released metal straps that fit it, they don't have the same size as the 47, the 41 has a thinner strap so basically you can't find any to change. in everything else it is amazing

    In general, it is good for its price. Don't expect amazing accuracy in the measurements, but it is at a good level. I expected a bit better with the battery. If you have the functions turned on, it lasts 3-4 days, especially if you also do some workouts or use the advanced sleep mode. To make it last about 7 days, you need to have the functions turned off except for, for example, the steps. So, I expected a slightly better battery than what it turned out to be.

    This review is about case size: 47 mm, colour: Black

    I've had it for about a month. With everything on - except for always on display - the battery lasts 5-6 days until it reaches around 20%, at which point I charge it. I haven't put it in water and generally avoid it since I've read several reviews saying it might develop a problem. The screen is bright and notifications come instantly (connected to an iPhone 16). I've set up contactless payments and it works flawlessly. Overall, I'm very satisfied with both the appearance and the features at this price. I don't think it's worth paying more for a smartwatch, since in 3-4 years at most you'll need to replace it. As for the measurements (steps, heart rate, calories), I can't compare how accurate they are, as I don't have another specialized device to compare with. However, it tracks sleep very well, recognizes when you wake up and how many times, as well as the duration.

Now I'm waiting to see how all this will end, just stay away again. I spoke with the service and they told me I have to send it again, I'm in trouble and left without a watch

    As a watch, it is very good. I faced the same problem twice. In the first month of its operation, it had a battery problem, it runs out in just 12 hours. They replaced it for me. The second watch arrives, and in the first month of its operation, the same problem again, the battery runs out within 12 hours. From the comments I read, the problem seems to be general, many people have the same issue. Maybe we should report it to Xiaomi Greece?

    Very good and with many functions but! After the first contact with water (as it is supposed to be resistant), the problems started. The battery dropped suddenly without use, then it overheated while charging (in one hour it charged up to 50% and then in another hour it dropped to 20% without use), the autonomy afterwards was terrible. I did 3 factory resets, without result. In the end, I returned it, but there was no replacement, because supposedly it was not available at the same price I bought it in any Skroutz store...

Description & Specifications

The Xiaomi Watch S4 stands out with an interchangeable bezel, premium design, and a high-brightness AMOLED display. With HyperOS 2, GPS, Bluetooth calling, 150+ sports modes, and up to 15 days of battery life, it is the ultimate smartwatch for any occasion.

What's New with the Xiaomi Watch S3

  • The brightness of the Watch S4's display is significantly improved, reaching up to 1500 nits compared to the Watch S3's 600 nits, enhancing visibility in bright environments.
  • The Watch S3 uses two level buttons for navigation, while the Watch S4 replaces one button with a rotating crown, offering a more intuitive and smoother scrolling experience through the menus.
  • The Watch S4 is upgraded to Bluetooth 5.3 from the Watch S3's Bluetooth 5.2, providing more stable and efficient connections with lower battery consumption.

See here for a comparison of the features of the two models.

Why choose it

  • Interchangeable Bezel (Bezel Design): This is its "magical" feature. You don’t just change the strap, but the entire bezel around the screen. As soon as you snap on a new bezel, the watch automatically recognizes it and changes the watch face to perfectly match your new style!
  • 1.32" AMOLED Display with 1500 nits: The 2026 display is brighter than ever. The colors "pop" out of the crystal, and using it under the intense Greek sun is now a pleasure, not a challenge.
  • HyperOS 2.0: Xiaomi’s new operating system makes the watch fly. The connection with your phone (especially if you have a Xiaomi) is instantaneous, and notifications now arrive more cleverly organized than ever before.

Health & Technology

  • 98.5% Accuracy in Heart Rate: With the new sensor, measurements approach the accuracy of medical chest bands.
  • Dual-Band GNSS (5 Systems): For those who run in the city, GPS locks in seconds and doesn't lose your route among tall buildings.
  • AI Sleep Tracking: Provides you with a complete analysis of your sleep quality and suggests ways to wake up with more energy.

Battery: Forget the Charger

  • 8 Days Battery Life: With typical use, the Watch S4 lasts for 8 days.
  • Fast Charging: 5 minutes of charging is enough for 2 full days of use.


Smart Functions that Make Life Easier

  • Bluetooth Calling: Crystal clear call sound thanks to the upgraded microphone with noise cancellation.
  • NFC Payments: Pay for your coffee simply by bringing your watch close to the POS (via Xiaomi Pay).
  • Gesture Control: You can perform certain functions (such as rejecting a call) just by moving your wrist.

Owner of this particular smartwatch for 3 months now, always on my wrist, so it has been tested quite a bit and I can give a full review. It was purchased for about €145.
During the time I've had it, it hasn't given me any glitches or problems.
Personally, I consider it a very beautiful watch whose design and build give you a premium feel. It's also nice that you can change the crown and, combined with another strap as well as the many watch faces available in the app, from one moment to the next, you feel like you're wearing a different watch. The strap it comes with is completely uncomfortable, so it was changed immediately.
Its screen is very good, clear with good resolution and brightness, and responds instantly.
Its measurements are relatively good. The heart rate readings are accurate. In oxygen and step measurements, there are some deviations. It measures distance well, as well as sleep duration (it even records short naps).
Notifications come through normally, depending on what you have set to show. For those wondering, you cannot reply to messages via the watch. You can answer calls normally.
Disconnections with Poco X3 phone, I have not noticed. The contactless payments with NFC have been incredibly convenient for me, which I consider a big plus. It works seamlessly with National Bank's Mastercard debit and credit cards.
The battery does not last 2 weeks as stated. With measurements enabled in smart mode and the screen activating with wrist movement, it lasts about 6-7 days. With the screen off and measurements enabled, it gave me about 3 extra days. Now, if you have everything off, then yes, it can last 2 weeks, but what's the point?
The speaker and microphone of the watch are ok. It sounds good on calls, but I would have preferred the speaker to be a bit louder with volume adjustment. In a quiet place, you will be heard and mainly you will hear just fine. With a little noise, there is an issue. Since some mention waterproofing, in the shower where I use it, there is no problem. In a pool/sea, I haven't tried it and I don't know if I would trust it.
The Mi Fitness app runs and syncs just fine.
In conclusion and overall, I think it is worth it and is a very honest watch for its price and what it offers.
If a couple of little things were fixed, it would be the ultimate value for money, so 4.5/5*

DO NOT PUT IT IN WATER. Despite the fact that it claims to function in water, after using it in a pool it started showing some weird things on its screen and after a while I noticed that even with zero usage, its battery barely lasts 12 hours. Now I'm dealing with the warranty supposedly for repair, but it's not great having to pay 20 euros for shipping, which the warranty does not cover.

Edit 25/10/25. After the "service" I was informed that the watch was completely replaced, so the problem is probably known and they just brushed it off, otherwise they would have just replaced a component.

    Honest for its money!
    Very good screen, plenty of features, good battery.
    Very good for everyday use.
    4 stars because I would like slightly more reliable recordings.

    Very beautiful and elegant watch. The 41mm size is ideal for a woman's wrist and the Mint Green color is even more beautiful up close. The screen is bright, the battery lasts long, and the health and fitness functions are especially useful. So far, I am very satisfied with my purchase.

    I have had it for 6 months. I only changed the bracelet and put on a metal one and it looks much nicer. The watch is awesome, it hasn't shown any lag or defect. I use it with very intense sweating and I don't take it off when I shower. It hasn't shown any problem.

    This review is about case size: 47 mm, colour: Black

    Owner of Apple Watch and HUAWEI Fit 4 pro, I have to say that this particular one is quite "poorer." Of course, the price is also quite low, but it remains basic.
    Don't expect advanced features or other goodies. Here, things are simple, and in general, it stays at the essentials.
    Measurements are relatively accurate and good build quality are positives. The battery is also good, but nothing special... If you activate all the functions (which are not that many), the battery in my hands lasts 4-5 days. Much better than an Apple Watch, but behind the (much more advanced) fit 4 pro.
    A big minus is the charger, which is the classic one with pins and not wireless.

    Beautiful design, many functions.
    The battery life depends on the functions that are enabled and the programs the user uses.
    I have notifications enabled from specific mobile apps, the walking and calorie functions, I don't answer calls with the watch, I don't have NFC enabled, I chose a low-power face and I haven't used any sports program. The battery life ranges from 12 to 14 days.
    At some point I answered a call and noticed that the speaker volume is low... In general, you need to have the watch close to your face to hear and be heard.
    Finally, I didn't try it in water to avoid possible problems... "I take precautions just in case!" :-)

    Beautiful watch but to pay with NFC you need to have cards from specific banks and they must be exclusively MasterCard. Also, in the two days I've been wearing it, the "ring" around the watch got lost, which comes off very easily, at least on mine.

    Good battery, good appearance. Average in measurements, considerable deviation in distance, heart rate, oxygen, etc. compared to other watches and with an oximeter (to test it). The app is one of the worst.

    Very good build quality. Easy to use. Beautiful UI. Great integration with iPhone 14. Not very accurate in its measurements (e.g. shows 37.1 temperature instead of 36.6). Finally, I would like the ability to install simple apps on the watch (some light games, AI tools, communication provider apps, etc.).

    Very good smartwatch, it is more than worth its money. The only problem is my phone, which is a Realme brand and interferes with the bluetooth connection. After many steps and a lot of settings, I managed to solve it.

    Very nice little watch and very light, I didn't expect to wear it even when I sleep. The screen is bright and with good response. The strap is very comfortable, you forget you are wearing it.
    The only negative is that it has a charging base and it is not wireless so you can put it on your phone's base.
    For my wrist, the 41mm is just right. The 47mm is a monster.

    I like it as a smartwatch, good battery life and nice appearance. I feel it comfortable on my wrist. Decent measurements and no connection problems with a Xiaomi phone. However, I had a strange problem and now it is in for service: during the night sleep I turn off the bluetooth on the watch, it locked itself with a pin... because bluetooth is off it can't be unlocked from the phone and a hard reset can't be done, since there is no such option in locked mode. So I am waiting.

    This review is about the colour: Gold

    The battery barely lasts 2 days. The measurements have discrepancies. Music cannot play independently... if you want that, you have to download songs directly to the watch, but there isn't enough storage. And generally, you always have to have your phone next to you for anything. NFC is easy to activate. Overall, it's only worth it for the gold bracelet. Did I regret it? Yes, I regret it. €188 is overpriced... no value for money at all!

    very good watch, it has been very convenient for me but the only disadvantage is that they haven't released metal straps that fit it, they don't have the same size as the 47, the 41 has a thinner strap so basically you can't find any to change. in everything else it is amazing

    In general, it is good for its price. Don't expect amazing accuracy in the measurements, but it is at a good level. I expected a bit better with the battery. If you have the functions turned on, it lasts 3-4 days, especially if you also do some workouts or use the advanced sleep mode. To make it last about 7 days, you need to have the functions turned off except for, for example, the steps. So, I expected a slightly better battery than what it turned out to be.

    This review is about case size: 47 mm, colour: Black

    I've had it for about a month. With everything on - except for always on display - the battery lasts 5-6 days until it reaches around 20%, at which point I charge it. I haven't put it in water and generally avoid it since I've read several reviews saying it might develop a problem. The screen is bright and notifications come instantly (connected to an iPhone 16). I've set up contactless payments and it works flawlessly. Overall, I'm very satisfied with both the appearance and the features at this price. I don't think it's worth paying more for a smartwatch, since in 3-4 years at most you'll need to replace it. As for the measurements (steps, heart rate, calories), I can't compare how accurate they are, as I don't have another specialized device to compare with. However, it tracks sleep very well, recognizes when you wake up and how many times, as well as the duration.

    Everything was fine until it broke down and the battery wouldn't last even a day, the compass and barometer were stuck, I sent it to service and after a month they sent it back with a replaced board but the problems remain. Now I'm waiting to see how all this will end, just stay away again. I spoke with the service and they told me I have to send it again, I'm in trouble and left without a watch

    As a watch, it is very good. I faced the same problem twice. In the first month of its operation, it had a battery problem, it runs out in just 12 hours. They replaced it for me. The second watch arrives, and in the first month of its operation, the same problem again, the battery runs out within 12 hours. From the comments I read, the problem seems to be general, many people have the same issue. Maybe we should report it to Xiaomi Greece?

    I will agree with those who write about its use in water! After just one use in water, the battery didn't last even a day compared to the 7-8 days it lasted initially. It's a shame because I was really impressed at first. I sent it back and I'm waiting.

    Very good and with many functions but! After the first contact with water (as it is supposed to be resistant), the problems started. The battery dropped suddenly without use, then it overheated while charging (in one hour it charged up to 50% and then in another hour it dropped to 20% without use), the autonomy afterwards was terrible. I did 3 factory resets, without result. In the end, I returned it, but there was no replacement, because supposedly it was not available at the same price I bought it in any Skroutz store...
