First of all..... i love my new phone... but here is something i discovered. My 3 year old loves to watch kids youtube... We (mommy and daddy) do not allow her to use our own personal phones that have active phone service. She uses my wifes out dates droid II to watch videos on it. When we go on trips and are away from our home network, I turn my phone into a hotspot and let her phone piggyback off of mine. 3 hours later from her watching streaming videos and and me using my phone with normal typical use, my battery is dead and my phone shuts off. I can think of many many solutions to resolve this isse but wow.. only 3 hrs? Would it make any difference if I synced via bluetooth instead of mobile hotspot? Its basically the same thing anyway. Post up on this about your battery life. I DO know my battery life is longer with my iphone X verse my iphone 6s.
