The Xiaomi Mi Band 4 (2019 model) introduced key upgrades like a vibrant AMOLED color display, customizable watch faces, an enhanced fitness sensor, and a 135mAh battery for longer use. Drawing from hands-on experience with Xiaomi wearables, here are seven essential tips to unlock its full potential.
As the first Mi Band with a color screen, it offers dozens of watch faces. On the band, swipe down to More > Band View and choose from 4-5 options. For more variety, open the Mi Fit app:
Go to Profile > Mi Band 4 > Band Display to browse neon, gaming-inspired, and minimalist designs. Tap to sync your favorite.
With up to 400 nits brightness, the screen excels in daylight but can drain battery and disrupt sleep. Activate Night Mode via Mi Fit: Profile > Mi Band 4 > Night Mode. Set it to trigger after sunset or on a custom schedule.
Track heart rate continuously for accurate daytime and sleep data. On the band, go to Settings > Heart Rate Detection > Detection Method. Choose continuous monitoring (third option) for best results, but note it impacts battery life.
Tailor notifications to avoid overload. In Mi Fit: Settings > App Alerts, toggle on, then Manage Apps to select specifics. Enable Receive only when screen is off for refinements.
Get gentle vibrations after an hour of inactivity. Customize vibration, set time windows, and find it in Band Settings > Inactivity Alerts.
Secure it with a 4-digit PIN via Labs features. It activates when removed.
Rearrange screens (Status, Workout, etc.) in Settings > Display Settings. Long-press and drag.
Pro Tip: Use the Find Phone feature to locate your paired device.
Adjust brightness, enable auto workout detection, and toggle DND directly on the band. These enhance daily use significantly.
