It is crucial for you be aware of the current charge level of your Mevo's battery, especially during your event.
When your Mevo is not connected to your phone, you may check its battery level by the green light on the back-right of the camera, just above the battery icon.
When the battery gets below 25% left in its charge, it will turn to red.
The light will start blinking red when it gets to less than 5% battery left, to warn you to plug your Mevo into wall power as soon as possible.
When charging your camera’s battery while plugged into AC power, the light will blink green indefinitely. It will do this even once the battery is 100% full.
Once your Mevo is connected to your phone, you may also check your battery’s charge level through the app.
Open your app settings, then check the battery icon at the top left, where you will a percentage of the charge you have remaining.
If you notice the Mevo battery percentage never reaches 100% when you first charge it, try fully draining the battery and recharging a few times. This will allow the battery and app to properly calibrate.
