Welcome RNewcomb!

One thing that caught my eye because I'm in the process of choosing another phone is a car charger for your smartphone or some other means of recharging your phone.

In terms of general everyday preparedness, I feel like we--as a group--are going backwards in terms of communications because of how quickly many/most smartphones run down their batteries. I feel sorry for folks who need to recharge their smartphones twice a day. Before smartphones, and especially before big, bright color screens became popular, most cell phones seemed to last many, many days on a charge--and that was before energy dense lithium ion batteries became common.
