Top positive review
An amazingly feature packed gadget, value for money
Reviewed in India on 23 September 2019
I have been using a Mi Band 3 already. So this is like an upgrade for me. Here is my review based on first few days usage. Will update the review again after a months usage to include other things like battery backup.
---------- Pros ----------
# New AMOLED display is so beautiful and fairly bright for out door
# New music controls (Volume, Track, Play/pause) works really well, but with a small delay
# Custom wallpapers is the best feature i found, at first sight the menus and UI looked like my old Band 3. But after setting custom wallpaper the whole band is in new level now
# 50m waterproof just like Band 3. I have taken my Band 3 under all worst conditions and never observed even fogging. Hope Band 4 also acts rugged
# 20 day battery is a good figure, will test and update the review after sometime. But if you don't connect it with phone, or turn off alarms it must last longer, if you use just as a watch
# Weather for current location(changes as you move), shows location name as well on screen
---------- More pros - Compared to MI Band 3 (All for little more money) -----------
# Larger AMOLED Display 0.95 in(Band 4) > 0.78 in(Band 3) > 0.42(Band 2)
# Can turn ON and OFF existing alarms directly from band(Something i really wish i had on my Band 3)
# Tempered glass top
# New sensors (3-axis accelerometer + 3-axis gyroscope). Well, i am not sure what its for
# Sharper and much brighter display
# Larger battery, 135 mAH(Band 4) > 110 mAH (Band 3)
# Screen guards can be applied due to broader face
# Charging time is less than Band 3, takes less than 2 hours
---------- Cons ----------
# UI could have been better, on such a beautiful screen, the current themes look bad
# Weather could have been added to home screen, Band 3 has it
# Could have added a switch to turn on high brightness for outdoor usage, because if you set brightness to 4(full) always it's really bright for indoors, but ideal for outdoors.
# The step counter is too inaccurate. Like any other brands this band also counts too many false steps. By the time i reach office in my car it shows me 1.5 KM or more, but actual walk is less than 0.5 KM. So better forget this feature
---------- Other Features ----------
# Lift hand to turn on display
# Sleep monitor
# Call and Message Notifications
# MI App comes with lot of features compared to other brands
# Find my device is very useful
Whether you should buy it? Yes, yes, yes. Go for it. Even if you are not a fitness freak, this band is quite useful for Call, SMS and Calendar notifications. Especially while driving, you don't need to pickup the phone to cancel or mute the call. And you can't ask for anything more for what you pay.
If you are ready to shell out more, you can checkout Amazfit Bip or Amazfit Verge lite models.
And as usual, Amazon delivered my Band superfast, in two days.
