The title of the thread refers to an overheating issue, but as timmaaa has discussed, it seems like your real issue is power drain.
Power drain goes hand in hand with heat generation, that is just a fact of how computers work. Solve the power issue, and the heat issue will go away.
And 110F is warm, but not anywhere close to the kind of heat required to damage the hardware of the phone, if that is what you are concerned about.
