Any ideas?
Shouldn't make a difference, however, a couple of things do come to mind... the broadcast frequencies used by US Mobile might not be some of the more "energy efficient" (eg, they don't penetrate physical infrastructure as well). It might also cause your iphone to scan for towers more often.
Not sure if this is a feature iphones have (modern Android do....at least stock and Samsung ones), but shortly after using my phone for a while (few weeks), I was asked if I wanted to change charging styles (eg, re-calibrate to charge to 80% to preserve battery life).... doing the 80% is definitely noticeable. That said, I was asked explicitly about this "feature", it wasn't forced on me. The %% goes down noticeably faster (at least for me).
