 Design and Display

  • Same strap fitting as Mi Band 3 
  • Larger 0.95-inch display 
  • Up to 400 nits brightness

Mi band 4 is the fourth generation of the series. The previous versions of the Mi band all featured a very basic black and white screen that could only display text and numbers. It couldn’t do anything else like changing screen saver or the appearance that much. But this is the first Mi band to fulfill all the absence that lacked previously.

Mi band 4 features a full-colored AMOLED touch display. The screen is large, bright, and colourfull, which means you can fit tons of information and data. The AMOLED display panel of the Mi Band 4 is capable of providing information about your physical activity as well as notifications on new text messages and voice calls directly from the connected phone. The display can also be used to find the phone or switch the music track with one tap. Similarly, it provides live weather and stock updates.

As for the strap, the simple buckle system is secure, comfortable, and is made from thermoplastic polyurethane.

Viewability is also significantly better thanks to the fact brightness climbs up to 400 nits. This means that indoors or out, it’s easy to see, and when combined with smart gestures to wake it up with a wrist twist, it’s the first Mi Band device to feel like it could be a smartwatch replacement.

Fitness and health tracking

Get ready to carry your trainer with you. The Mi Band 4 will keep track of all the basics: steps taken, distance traveled, calories burned, resting and active heart rates, and sleep. The footsteps measurement is not that accurate because it lacks inbuilt GPS. So, you can track your workouts with GPS if you don’t mind bringing your phone.

Talking about fitness mode, it includes several different modes like;

  • Outdoor running
  • Treadmill
  • Cycling
  • Walking
  • Exercise
  • Pool swimming 
  • Heart rate
  • Sleep tracking

There is a six-axis accelerometer that helps to monitor physical activities, including cycling, exercise, running, swimming, and walking. The device is 5 ATM rated and is designed to identify various swimming strokes, namely freestyle, breaststroke, backstroke, butterfly, and mixed-style.

Heart rate recordings — both resting and active — with the Mi Band 4 are decent.

Sleep tracking is another one of the Mi Band 4’s most active areas. It’ll track your deep/light sleep and time awake, and it’ll give you a sleep score from 1-100 by comparing your data to other Mi Fit users’ data.

Mi Band features

We’re surprised at how many customization options Xiaomi included in the Mi Fit app. One can sync their Mi band 4 to Mi Fit app and can get access to tons of exciting features like:

  • Vibration pattern: App allows a user to customize the vibration pattern so you can tell the difference without even looking at the screen.
  • Do not disturb: Getting bombarded with notifications, everyone hates that. So, with Mi band 4 you can turn DND mode on even without your phone nearby.
  • Night mode:  With the smart inbuilt Night mode in Mi band 4, your Mi Band 4’s screen brightness will be lowered after it tracks sunset.
  • Schedule for auto screen wake up:  We love the “raise to wake” feature in our smartphones. One can turn on the lift the wrist to turn on the screen automatically with the customizable response speed.

Battery and charging speed

With the bigger, brighter, and smarter display with additional features, you might think about the huge compromise in battery life. But the things are as simple here. Due to the larger capacity battery, the extra color and brightness don’t result in worse battery life – impressive, given the 20 days quoted on a single charge.

Powering the Mi band 4 is the 135mAh Lipo battery which can be charged using  2Pin Pogo Pin charging type. On our use, the battery used to charge from 0 to 100 % within 2 hrs.
