I know this is no where near to the battery life of the Mi Band 4, but both devices have completely different uses and usage. Peace! :)

Using my Oppo A77 the Mi Band 4 can control my spotify (play/pause, next/previous).

Though I found no matter what app I use to play audio, I cannot control the volume with the Mi Band.

My baby can go 18 days while those stupid galaxy and apple people have to take it off every night

Just upgraded my band 1 to band 4 ... I got the Chinese version as it's a bit cheaper.
I don't speak or read Chinese but luckily the app is in English.

If you go and manually unpair the band from the app it will revert to Chinese with no functions just asking to link to the app. If the band is disconnected from Bluetooth it will continue to work as normal until it connects to the phone next time.

Readability was also an issue for me with the 3, but that improved with mi band 4. You can adjust brightness on the band itself, and it really is a whole lot more visible in the sun.
Because of a shower of rain right now I really can't give you picture proof, and I wouldn't know how to post a picture either...
Buy you can set brightness into 5 steps from dark to bright, and I guess the setting into step 3 of 5 in mi band 4 corresponds with the brightness of the mi band 3.

Is there any difference between the global version with the the Chinese version with out NFC? I read in one place that if your band got disconnected from your phone, in Chinese version the language will change from what was set to Chinese. Is that true?

I use the Band3 and just bought Band4 for my wife. I use it for: daily steps, jog/walk, bicycling, alarms, notifications, sleep times and heart monitor. Battery really lasts. What else for the price?

Love my mi band 3, it show heart rate, footstep, notifications from sms and facebook messenger, analyze your sleep. Great product, worth more than costly fitbit ones. Keep it up Xiaomi

alejillo, 12 Aug 2019This is one of the worst products at least if you are using iOS.... moreWorks great on my android phone. my second charge now after 25days of use. I mainly use this for email notification, weather, steps, apps notification and skipping songs. Not sure why is worst device when it has all the features you need. People just don't know how to use it.

Guys, please listen to me.
This device is not going to replace your fitness tracker or smartwatch. It is just a gadget showing time and able to wake you up every morning. I dont understand why people really believes in thise device should measure deep sleep as garmin or fitbit. It is teenager watch, not adult watch:)

I have the Mi Band3 and one thing that I really have trouble with is trying to read the screen outdoors.
I have heard that the Mi Band4 has much better sunlight readability. Is this correct? If possible request you to please add comparative photos for sunlight readability for both the Mi Band3 & Mi Band4.

Thank!!

This is one of the worst products at least if you are using iOS. The app won't work with iPhone, just check the app rating in the app store. This band is not worth the plastic it is made of. Save your money.

Mark, 12 Aug 2019Dunno about that. U only charge every 3-4 weeks. So long i for... moreits easy but there materials that band is made of is not THAT durable, and it wear off. And its not only problem with Band 4, even Apple and Samsung have that problem because you cant skip material weariness.
After few months of such pulling it out and in, band will eventually fall off in worst possible time. Maybe now its all tight and fancy but trust me I had that problem with other devices that use such materials.

Can someone please tell me does it effecttivly tracks your sleep cycle ? Or does it just montior your sleep movements and determine your deep sleep stages when you are just not moving much? Also, can it effectively wakes you up during light sleep stage ?

palacinka, 12 Aug 201935€ and no GPS ??? who buys that crap lolSomeone who knows their way around and don't need gps. I use it for work to keep me in time in between clients. I like the size as i don't like wearing anything on my wrist outside work, plus the price is so cheap and does the job for me. So yeah i bought this crap.
