Is the plus battery life REALLY that much better than the regular? After my last real vacation last year, I decided that I needed a battery case. Use of camera. Away from a charger all day. Poor cell phone coverage. Phone had a tendency to go dead early. So I order the plus this time for a change. But I see Apple doesn't seem to carry the battery case for the plus phone. It would be nice to have a battery case at least for vacations. The apple case had a couple major advantages vs the 3rd party one I tried first. Lightling connection, so didn't have to worry about micro-USB. Transparent use, vs the third party one I had to push a button to start recharging phone.
