Like the previous version, the band features a 0.95” color OLED display with 120 x 240px resolution. It can display text messages from SMS, WeChat and QQ. The battery should last 14 days between charges.
The Honor Band 5 has an optical heart rate monitor as before (a slightly newer model, TruSeen 3.5, up from 3.0). Also, it gains an SpO2 sensor (blood oxygen saturation), which can be useful for the adventurous types (if you climb to high altitudes) or those suffering from certain conditions (e.g. hypoxia).
The band is water resistant up to 50m and features 10 sport modes, including stroke recognition for swimming.
The Honor Band 5 Standard Edition is available in China today (CNY 190), the NFC version is coming on July 29 (CNY 220).
