I got this because I thought it would fix some issues that I am having with fitbit band that are see the steps on my wrist rather than I had to take out my phone and the other one is syncing problem . fitbit band takes so much time to just sync which I thought, that this problem is not in the mi band 4. Altough indeed it is well made an elegant look.
But it turns out that it requires setting an online account with Xiaomi in order to activate the software that the band has it working on.
And after doing that it says 9 -10 times that band is not synced successfully( Pairing problems) . I lives in India so its obvious that I want English Language version but the whole band language appears in the chinese . This is the biggest fault they had to improve it.
Talking about battery life initially it would stay upto 10 days and then after 1 month it would decrease to just 5 days .
So in my opinion better go to fitbit or apple watches .
