The left one is an iconic representation of a satellite and tells you if you have a strong GPS signal. Mine sometimes blinks in the garage and then doesn’t track my actual location very well untill it finds enough satellites. The one on the right tells you how strong your cellphone battery is even if it’s Bluetoothed and not USB connected. So unless I’m using Waze on a trip, I don’t even get my phone out of my pocket any more since I can talk, play music, and know the battery level.
