Charge Your iPhone, Seriously!
A dead iPhone is pretty much useless. But even if you have some power left on your device, a low charge could be causing poor reception. If your iPhone is low on battery, it’ll have a harder time searching for the nearest cellular signal. So any easy thing you should try is to simply keep your device charged past 50 percent. That may sound obvious, but it could be an easy remedy if your iPhone is frequently low on battery by the time you get home from work or school. If that’s the time you get poor reception, try plugging in your phone first.
