The VO2Max adds an advanced touch to the health monitoring features and it accesses the amount of oxygen your body can take and use as energy. Now, this is an important stat since it is a key indicator of how your body capacity is improving. The Huawei Band calculates the data by analysing the stats from your workouts which is eventually compared with the heart rate. Huawei has apparently partnered with Firstbeat Technology, a company that promises 95-percent accuracy in its readings. The heart rate sensor on the Huawei Band 2 Pro is active all day and it also comes with an onboard GPS. Huawei claims that the battery will last for 21 days even with the hear rate monitoring, however, the battery backup will diminish to a rather disappointing 3.5 hours with the GPS module active. In order to save the users from the peril of over exercising the Band 2 Pro comes with a recovery time indicator. The TruSleep measurement is touted to monitor different stages of sleep including REM. Moving on from the fitness features, the Huawei Band 2 Pro also beams incoming call alerts, phone reminders and is water resistant up to 5ATM. That being said the Huawei Band 2 Pro has carried over most of these features from its predecessor and has reworked on a fitness first approach rather than a smartwatch with fitness features. Huawei is yet to announce the Band 2 and Band 2 Pro release date and pricing.
