The battery life on all of our iTouch smartwatches greatly depends on your personal usage
However, the battery life for most iTouch smartwatches can last for about 12 hours with regular usage
Also, if the watch is idle for more than a month, it may not be able to power on because the battery has fully drained. Plug in your watch into the charger. It should power up after a few minutes of charging.
We do suggest charging your watch by using a desktop/laptop computer to maximize battery life and charge capacity =)
