If you're encountering difficulties charging your EZVIZ camera, here are some steps you can take to troubleshoot the issue:

1. Check the power source: Make sure the power outlet you're using is working properly. You can also try plugging the camera into a different outlet.

2. Check the power cable: Make sure the power cable is not damaged or frayed. You may also try using a different charging cable to see if that solves the problem.

3. Reset the camera: If there is still remaining power in the camera, you can try resetting the camera by pressing and holding the reset button for about 10 seconds. This will typically restore the camera to its default settings and may help resolve any charging issues.

Involved model: BM1/BC1/HB8/BC1C, etc.

Kindly note the actual battery life will vary depending on environmental factors, network stability, and the frequency of camera activities. 

Thus, to optimize the battery life, we suggest you check the following:

1. Low temperature. As the battery inside is a lithium-ion battery, if the temperature is low, the charging would be slowed, so you may need to charge more often at temperatures below 0°C. 

2. Weak Wi-Fi connection. Please ensure the network connection is good and there is no barrier or radio interference between your camera and your router causing an unstable network. You may open the EZVIZ mobile app > enter camera Settings > Network Settings and tap Wi-Fi Signal Strength to test the signal.

3. Meanwhile, you can try the below settings to reduce battery drain:

- enable Power Saving or Super Power Saving mode (only active live view can wake up the camera) in camera Settings > Working Mode or Battery.

- decrease detection sensitivity in camera Settings > Intelligent Detection.

- draw detection areas in camera Settings > Intelligent Detection.
