EZVIZ no longer supports Internet Explorer 10 or earlier versions, and the site may not behave as expected. Please upgrade to a newer browser.
Kindly note that the actual battery life will vary depending on environmental factors, network stability and the frequency of lock activities.
Thus, to optimize the battery life, we suggest you check the following:
1. Weak Wi-Fi connection. Please ensure the network connection is good and there is no barrier or radio interference between your lock and your router, causing unstable network.
2. Please make sure your device is running on the latest firmware.
3. Meanwhile, for smart lock DL03, DL04, DL50FVS, you can try enabling Power-saving Mode in device Settings>Battery to reduce battery drain.
If you need further assistance, please contact the EZVIZ support team for personalized guidance.
