[Q] Google Gear and battery life topic

I was wondering, does anyone use a Android Wear smartwach with the OPO and could share some experiences with the battery life? I just ordered a OPO and was wondering how much battery it drains. I currently have a Moto G (2014) paired with a LG G Watch R and it affects the battery life quite a lot (more than I expected to be honest).

Cheers! :)
