The battery life may vary according to the settings, operation conditions and other factors. Sothe actual result may differ from the laboratory data. The HUNT Fitness Study indicates that people who maintain a PAI score of 100 or higher showlower risk of hypertension, heart disease, and type-2 diabetes. HUNT Fitness Study: This study wasconducted by Professor Ulrik Wisloff of the Faculty of Medicine, Norwegian University of Science andTechnology. It lasted for more than 35 years and had more than 230,000 participants. To use thisfunction, all-day heart rate monitoring must be enabled. Balanced GPS Mode: Turn on heart rate monitoring and GPS movement (single frequency, GPS + Beidou). The low temperature mode is turned off by default andneeds to be enabled in the watch settings. After being enabled, whenever the temperature of thewatch surface is lower than -10°C, the watch automatically enters low temperature mode, and onlylimited functions can be engaged at this time. Due to the physical characteristics of lithiumbatteries, the endurance of watches in low temperature environments will be affected to a certainextent. The battery life while in ultra-low temperature environments may vary according to thesettings, operation conditions and other factors, so the actual result may differ from thelaboratory data.

Ultra-low temperature operation with GPS off (-10­°C to -30­°C): Wear the watch all day with a static watch face as the watch enters ultra-low temperature mode; raise wrist to see watch time 100 times; 150 pushed messages a day; bright screen operation for 5 minutes per day.

Well, Zepp Health (formerly known as Huami) has beefed things up in the durability department, slapping it with more military grade certificates, brought in a new sensor, greater mapping support and still managed to keep it affordable. If you take your training and recovery seriously, there are series of insights on board powered by analytics firm Firstbeat who offer similar features for Garmin and Huawei watches. This gives you an insight into training load, recommended recovery time, VO2 Max and training effect insights based on FirstBeat's heart rate based algorithms.

Straps for the Amazfit T-Rex (Pro)

To process the one-tap measurement and other manual metric measurements, please wear the watch tightly at one finger-width from the wrist, and keep your arm still for best results. Movement, and environmental and physical characteristics can affect speed and accuracy of monitoring and measurement. Typical usage scenario: Heart rate monitoring is always on and measures at 10-minute intervals,sleep monitoring enabled; static watch face selected; 150 pushed messages a day; receive 3 callnotifications per day; raise wrist to see watch time 100 times; test blood-oxygen 5 times per day;bright screen operations for 5 minutes per day; GPS running for 90 minutes per week. Turn on Bluetooth when you need to sync data, receive notifications, update firmware, and set alarms.

The battery life may vary according to the settings, operation conditions and other factors. So the actual result may differ from the laboratory data. Corresponding sports modes include: Outdoor Running, Treadmill, Walking, Indoor Walking, Outdoor Cycling, Pool Swimming, Rowing Machine, Elliptical. The accuracy and sensitivity of the workout recognition feature varies from person to person, and are related to the posture and proficiency of the user during their workout. Short workout duration or frequent changes in posture may not trigger the automatic recognition feature. When you are driving a car or taking a bus, or taking part in other such activities, accidental recognition may be triggered if these activities are particularly similar to the selected workout mode. When you are conducting outdoor activities, if the GPS signal is poor or the AGPS data information has not been synchronized with the mobile phone for an extended period, these outdoor activities may be assessed as indoor activities. As a smartwatch, the T-Rex Pro offers everything you get on the T-Rex and from our time with it and nothing really new from what we could see.

The SpO2 sensor here is new to the T-Rex range and offers on the spot measurements but won't continually monitor SpO2. It will also prompt you to do the test when you hit ascents over 400 metres and will do something similar when you hit 4,000m+ ascent. After looking and comparing with various models out on the market I decided on this watch. I have been impressed. I have had this watch for about 3 months. And a pre-populated list of existing applications on your mobile device will not appear in Amazfit App. Only applications that generate notifications will appear in the list and will populate over time as notifications arrive.Sleep monitoring can record night sleep and naps that last more than 20 minutes. Any sleep period that starts or ends between 10pm-8am will be recorded as night sleep, and if you fall asleep within a 60-minute window at either side of your night sleep period, it will also be recorded as night sleep. Sleep recordings that start or end over 60 minutes outside your night sleep period, and that do not overlap the 10pm-8am timeslot at any point, will be recorded as a nap.
