5) Why is my watch running out of battery power fast?

Amazfit GTR 2 battery life is 14 days.
1. Turn on the voice assistant function/all-day wear/all-day heart rate detection/sleep monitoring;
2. Bluetooth call for 30 minutes/week, music playback for 30 minutes/week, exercise three times a week and turn on GPS for 30 minutes each time;
3. Raise the wrist to light up the screen 30 times/day, 150 messages push/day, and blood oxygen test 2 times/day.
The most power-consuming functions of the Amazfit GTR 2 watches include motor vibration and the light of the screen. If you often run for exercise, receive pushed messages frequently, or set a much too long screen-on duration, then it's normal that your watch runs out of battery power fast. If you don't use these functions often, fully charge your watch, turn on Do Not Disturb mode, set the brightness of the watch to the lowest level, turn off the Bluetooth, turn off the AOD mode, set your watch to the default watch face, and then observe the power consumption after placing it still for 24 hours. If the power consumption is over 5% please submit your feedback to help us analyze and locate the issue.

6) My Heart Rate readings seems inaccurate. What should I do?
Inaccurate heart rate readings appears to be due to the fit of the device band itself. A loosely fitting band that moves around at all, or that has notable gaps between the device and the skin, can easily cause an inaccurate reading. For the most accurate heart rate readings, you will want to be sure you’re wearing the device on the top of your wrist and it's fairly snug against your skin.

As the heart rate sensor is basically a pulse oximeter which monitors the perfusion of blood to the dermis, it’s prone to inaccuracies. That’s because skin perfusion — a measure of how much blood flows through your skin-varies significantly from person to another. Especially the ones who have dark skin, hairy wrists, tattoo, and scar.

If you’re seeing a reading that doesn’t look quite right, please check the following:
1) Take a second measure if you thought the reading isn't right.
2) Keep it close to your skin and do not swing the arm
3) Clean the heart rate sensor

If the issue persists, please confirm which heart rate detection is inaccurate.
1) Please note that single HR cannot be detected during exercise.
2) If the heart rate is abnormal during exercise, please attempt the following steps when you do an activity next time.

If you still have the same issue with the latest ROM version, please open Zepp app, tap Profile, swipe up till you find Settings, tap it to find Behavior tagging, tap Behavior tagging and Running. Keep the device near to your phone and make sure there are no objects between them. Then, tap start and submit data with the following steps after you finish the workout.
