While I was waiting at the airport the other day, I couldn't help noticing all the iPhone users crowded around the charging stations. Every spare outlet had somebody's charging cable coming out of it. I have always refused to use phones without removable batteries for this precise reason. I carry several spare batteries for my Note 4 in my briefcase, together with a portable charger. If I get close to running out of battery after a long day, I just swap a battery, and am going again. Until somebody comes up with a 2 or 3 day battery for these things, this is a deal breaker for me. I don't even like the new Samsung phones that don't open up. I might just keep my Note 4 for a while. While I'm at it, some people are even paying for the privilege to charge up. Would you pay 2 bucks to charge your phone?
