THINGS WRONG WITH MY PHONE, AS OF LATE

I get an upgrade in August 😅😅
  1. When I unplug it at 100% and use it on my six minute ride to school it goes to 73%
  2. It dies at anywhere from 35 to 12%
  3. Sometimes when it's locked the screen will stay black after I try to unlock it for three to ten minutes
  4. Sometimes it won't let me press anything until I restart it
  5. My apps spontaneously close every ten to fifteen minutes
  6. It won't let me flip my camera, so I can only take selfies
  7. Sometimes the exposure will get all weird and then it will just fade into white
