Does Clip have power saving mode?

Yes – if you forget to turn off your Clip, it will shut down automatically after a set amount of time. 

If you don't use or move your Clip for 30 minutes, it will go into low-power mode to preserve battery. To wake up your Clip, just move it and it will be back in normal mode. 

If the clip isn't used for 2 more hours, after going into low-power mode, it will automatically shut off. To wake it up, put it on the charger or press the power button.
