This is what confuses me. Who doesn’t have access to a charger at some point ? Seems most are purposely not charging just because. Throw it on the charger for 20 minutes.
This. Just speaking for myself (and my evil twin Skippy), I have a charger at home and one at the office. I charge up before I go to work. And then at times when I see the battery dropping to the high 60's/low 70's, I just put it on my Samsung charger that's on my desk. And I let it charge until I need to use the phone again.
Plus there are all sorts of portable battery chargers out there that aren't that big or obtrusive to carry around. Wouldn't surprise me if some sort of battery case comes out for the phone as well.
