Similar to the Honor Band 4, the Honor Band 5 packs Huawei’s TruSleep feature. As suggestive of its name, it helps track and improve your sleeping habits. And on top of that, it dims the band’s screen to help you sleep better. And as you’d have guessed, it’s not enabled by default.
Thankfully, you can enable it easily via the Band setting at the top. All you have to do is toggle the switch for Huawei | Tru Sleep.
