My 6 has started doing this just after its 2 year anniversary. I bet it has something to do with battery age as well

  Exactly the same for my 2-year old 6.

  This can be "fixed" by resetting the battery data on the phone and then letting it completely discharge before charging. I've had it work myself several times (I own two of every model iOS device for app testing purposes).
