It isn't dangerous, no.
It isn't ideal as lithium batteries hate the warm. Think of lithium batteries being perishable foods, they prefer the cold, in fact for long term storage they are kept in refrigerators.
If the phone was at these temperatures 24/7 then the battery would quickly deteriorate and run-times would take a dive, but for a few hours a day it is unlikely to make much difference considering most people replace these phones after a couple of years anyway.
