What battery are you at?
Not your phone. You. Is it in the 70-80% or the 15-20% range? Or maybe it is 3-5%...
If your phone was at 3%, you would use it carefully until you can plug it again.
Generally, when we are at low battery, the critical voice and the hungry ghosts take over. It might be a better strategy to hold things off until we have more range.
