    New to LTE. if I am in an area without LTE for a few days, will my battery life be affected if I leave it turned on?

    Yes, it's best to just turn it off if you know you are outside of an LTE service area.

    The iPhone 5 uses one chip for all of its cellular communications. Therefor turning off LTE is irrelevant as the chip is still activated for HSPA+.

    However I am on Verizon, so no HSPA. Still a little confusing to me why it would affect battery life if I'm not actively downloading on it; does it constantly search for an LTE signal?

    I drove across the US with my Verizon iPhone 5 and never noticed any difference in battery life whether I was in an LTE area or not. I don't think it matters.

    From my personal experience, LTE and 3G show no difference in battery life. Both drain the same, which is significantly greater than wifi.
