I was hoping I'd be able to say this when I got my 6 and it turned out to be true, those bands on the back of the phone are much better at finding and keeping signals than my 5 was. The 5 always seemed to drop and go down to 1x on Verizon in the Seattle area. As a result, my battery drained incredibly fast; I usually had to plug it in on my drive home from work. Yesterday, I didn't think about plugging it in until I went to bed and I was still at 45%. It's amazing what a difference these make. I grew accustomed to plugging in my phone midday. Now I get ready to do that, look at the battery, and ask why I should bother to do so. It's the best improvement the phone has.
