There are two main scenarios. Please test based on your specific situation to see whether the issue persists.
Short standby time
Description: I used the device once on Monday. Then I didn’t use it for two days. When I connected and used it on the third day, I found the battery was already depleted.
Test:
Charge the device to 100% (after the LED turns green, keep charging for another 15 minutes).
Press and hold the Record button for 16 seconds to reset the device. The reset is successful when the indicator light turns off.
Then, do not use the device and observe how long it lasts before the battery runs out.
Short recording time
Description: After purchasing, I charged it to 100%. Today I made some recordings, and the device was almost shut down (needed charging). The main issue is that the total recording time is less than 10 hours.
Test:
Charge the device to 100% (after the LED turns green, keep charging for another 15 minutes).
Press and hold the Record button for 16 seconds to reset the device. The reset is successful when the indicator light turns off.
Start continuous recording until the battery is depleted and the device powers off. Then recharge and reconnect to the app to transfer the recordings, and check how many hours the recording lasted.
