Ok.. here's an update. I went Sprint yesterday because my iPhone 6 no longer has Apple Care. Sprint stated he's has seen multiple customers come in with this particular problem and no solution. Being that I have protection plan he told me I can file with Asurion and get another phone. At this point fine whatever I will gladly pay 200.00 and he stated they are shipping out brand new 6s to replace 6. Go to the site and ordered options were grey or silver. Never had gray so I chose that. Got my brand new phone today with everything completely new. Updated phone at work working perfect. Got home and my apps downloaded with my wifi. lo and behold it started acting up again. So I'm thinking it has to be one or a few of my apps. Reset the new phone to factory and manually downloaded only apps I use on a daily basis. Have no problem now. So I'm assuming it's either apps not upgraded to iOS 10 or something else. Clearly it isn't the phone.
