Amazfit Bip has many wearable electronics, so I decided to compare several similar models of the same class and tell you what the differences are. Illustration: Svetlana Chuvileva / Wylsacom Media

There are more and more wearable gadgets, and new classes of devices are also emerging: between simple fitness trackers and smartwatches, there is room for other equipment. Thanks to this, the entry-level smartwatch class is developing. On the one hand, they are not so expensive, but on the other, they are still more advanced than bracelets with small screens.

Visually, Amazfit Bip S and Bip U are very similar, but the differences can still be found if you look closely. The Amazfit Bip U has a slightly less elongated body – this is noticeable when both watch models lie next to the switched-on screens.

The watch cases are made of polycarbonate, and on the right side, there is a physical button. The wheel can “wake up” the clock, go back one step in the menu, and a long hold starts the application. Which one – you can choose yourself in the settings.

Watches are not only in classic black color. There are several options.

Amazfit Bip S: black, pink, white, and orange.

Amazfit Bip U: black, pink, and green.

The silicone straps are replaceable and can be changed to suit your mood or color. The mount is standard, so there will be no difficulty in finding suitable accessories.

Moisture protection

The watch has an identical level of protection against moisture. This is 5 ATM. In simple words: splashes, rain, swimming without deep diving is not a problem for them.


Displays differ slightly in size, but the fundamental difference is in screen technology. If the Amazfit Bip S watch has a transflective TFT screen under the third generation Gorilla Glass with a diagonal of 1.28 inches and a resolution of 176 × 176 pixels, then the Amazfit Bip U has a conventional TFT screen with a 1.43-inch diagonal and a resolution of 320 × 302 points.

The good thing about a transflective screen is that it consumes energy very modestly: the backlight works at night, and during the day, it simply reflects the light. But this screen is not as colorful and bright as the more familiar screens. Therefore, the feeling depends on the lighting, and Amazfit offers a watch with different displays. Some need a prettier picture, while others vote for functionality.


The watch works in tandem with devices on iOS and Android and connects via Bluetooth 5.0, notifying new messages and calls. You cannot talk on the clock, they do not have a microphone and a speaker, but you can reject a call or send a message that you are busy or another template answer.

The Amazfit Bip S has 10 workout modes and two customizable watch faces, and over 40 ready-made watch skins can be downloaded via the phone app. The clock shows the weather forecast. You can switch tracks on your phone. Simultaneously, the Amazfit Bip S watch has both a compass and a GPS, which the Bip U does not have (but the Pro version does). But Amazfit Bip U already offers more than 60 types of workouts, and for productive work, there is a built-in Pomodoro tracker.

Both devices count steps, measure heart rate, distance traveled, keep track of calorie consumption, display notifications if you sit still for a long time, and show the weather and work as a remote control to control music.

Among the important additions to Amazfit Bip U, it is necessary to highlight the level of stress and measurements of the level of oxygen in the blood.


In terms of battery capacity, Amazfit Bip S is inferior to its fellow Amazfit Bip U: 200 mAh versus 230 mAh. However, due to a very economical screen, they work for about 15 days, and with an economical mode up to 40 days, the Amazfit Bip U has an operating time of about 9 days.

The watch is charged through magnetic chargers, mounts of different types, so the cable for Amazfit Bip S to Bip U does not fit.

What is the difference between Amazfit Bip U Pro?

The watch has the same design, dimensions, and screen as the Amazfit Bip U.

Of the fundamental differences between the Pro version, it is necessary to highlight the built-in GPS and GLONASS, which the Amazfit Bip U does not have. Therefore, you do not need a phone to train outdoors. The watch will autonomously build a map of a run or a bike ride.

Also, the Amazfit Bip U Pro has an electronic compass and microphone. You cannot answer calls using the microphone, but you can control the Amazon Alexa voice assistant.

For convenience, I collected the data in a comparative table:
