Maps - cache use and duration

I think I forgot to thank you for that suggestion.
It worked but drains the phone really fast

True. Two options. Cache the maps around you, and then turn off hotspotting, or bring along a playing card size USB brick, that will power or recharge your cell phone, while using it as a hotspot. It can also be used to charge your tablet, if needed, but not while connected to the RC, because the RC uses the same port.
