Xiaomi's "performance mode" will certainly not, it must maintain the announced battery runtime, as specified by the device. Custom Firmware with "performance mode" may be available ;)
The display does not show permanently, to maximize to runtime device on battery. "raise wrist to view info" is optimized for reliability and fake detection of "raise wrist to view info", again for maximize to runtime device on battery.
To se toho někdo bude muset z CZ komunity ujmou a pro MB4 vytvořit vlákno pro Czech Firmware. Bohužel ze strany @MRMR a @rendal bude dále podporován jen Mi Band 3, MB4 nevlastníme a o koupi do budoucna zatím neuvažujeme. @xpaulos2 již MB4 má takže o SK vlákno je zřejmě postaráno. Co takový...
