What to do if the Xiaomi Outdoor Camera BW300 battery drains fast?

Please refer to the following troubleshooting steps:
1. The Xiaomi Outdoor Camera BW300 features a built-in 4900mAh high-capacity rechargeable battery. Typical use mode can realize 120-day long life.
Test conditions: Open night vision function, the default black and white night vision; motion detection in the sensitivity of the trigger; daytime plus night recording 20 times a day; daily daytime live broadcasting 1 time (30 second/time); night live broadcasting 2 times a week (30 seconds/time); two-way Call: 2 times a week (30 seconds/time); sound and light alarm: 2 times a week (30 seconds/ time);
2. The duration can be caused by the following reasons: 
(1). Use the full-color night vision function;
(2). The frequency of triggering events in the surrounding environment is high;
(3). Check the live video frequently;
(4). Try to switch the night vision mode in the Mi Home APP;
(5). Adjust the detection sensitivity and detection interval.
3. When you receive a new device, please bind the Mi Home APP first, update the firmware and then use it fully charged;
4. Cameras installed in indoor or heavy traffic, frequent triggering of the camera video, will significantly reduce the battery endurance;
5. Outdoor camera single charge takes about 3 hours, support for external power supply equipment power supply (such as power cord, charging treasure, etc.);
6. Low-temperature environment or charging state use of this product will affect the standby time. Please do not use the live screen preview function for a long time in the charging situation, so as not to lose battery endurance.
Note: 
1. Please make sure to use a standardized and safe charger (5V-2A);
2. Please note that the battery endurance of each camera will vary depending on the number of motions detected, recording duration, and ambient temperature.
Here are some tips to reduce your power consumption:
1. Reduce the working time of the camera under too high or too low-temperature conditions, and the camera supports working in the environment of -20℃~55℃;
2. Ensure that the signal strength between the camera and the indoor unit is strong. Also, check the Wi-Fi signal;
3. In the detection settings, select only human detection instead of all detection types, and reduce the detection sensitivity by going to [Function Settings] >> [Motion Detection].
