Yeah, I used the Mi Fit All In One app, and followed all the steps but didn't work. I checked every single post from @MagicalUnicorn and tried every single thing, but nothing worked. I'm really sad right now ngl, and convinced that the problem is something in hardware stuff.
I did it, but unfortunately it didn't work, the battery still runs out very fast. I think there is no solution, the problem must be in the hardware or something. Thank you for the help anyway.
The last update was V1.0.9.66. And when I try to look for new updates in the Mi Fit app, it says that the latest one is already installed. I will do it, but why the official app doesn't recognize new updates?
I tried two times already mate, but didn't work. I also tried change the app (Mi Fit > Notify) but still didn't work.
I think doesn't have a solution for my problem. Maybe in the future Mi release a firmware that will fix this.
Can anyone tell me a firmware that solves the battery problem? The battery of my Mi Band 4 lasts less than 24 hours, when it should last between 15-20 days.
Ps: I have practically all features disabled like cardiac monitoring, sports functions, notifications and all the others.
