So far so good after returning the first one for failed battery

Loses considerable battery while shut off.

The app drains my smart phone battery very quickly

This caused me to think the camera was malfunctioning, or the battery was dead.

Battery isn't the issue I've had.

One thing I will say is that this is the smallest action cam I've seen yet with decent battery life.

I get 30 minutes, tops before the camera turns off and the red LED (low battery warning) comes on

I charged it the night before a ride and then decided to charge it again in the morning to see if it lost any battery overnight.

Camera seemed easy to use but I cannot attest to how well it worked as it was lost on the first day
