While at home, My 5s has recently been having a weak LTE signal (verizon) over the past month. So low that it's constantly switching between LTE and 3G. However, I'm on wireless when I'm at home, so I wouldn't think that my phone would care about cellular strength while on a wireless home network. My question is: should I be worried about this eating up my battery? I've heard that switching can kill battery life, so can switch off cellular while I'm at home but it is kind of annoying to constantly be switching it on and off when I leave the house or come home. And why does my phone care about cellular strength while on wireless, or is it just visual?
