Leaving iPhone 5S in car?

[aristobrat]

FWIW, this is what Apple says:

Thermal Considerations

It is important to keep your iPhone out of the sun or a hot car (including the glove box). Heat can significantly degrade your battery’s performance.

Dewpoint (humidity condensing) is met from the opposite direction.

For example taking a glass of ice water (cold) out side in the hot humid summer heat causes condensation to form on the outside of the glass. Bringing a cup of coffee (hot) into the cool AC does not meet that dew point.

I move around a lot of camera equipment. Keeping it in their respective bags when going from inside in the A/C to outside into the heat is a requirement. The other way around doesn't matter.

Brings an overly chilled phone out of the cooler into a humid environment will cause condensation

Yeah. I left a penny in my car for a whole week. I used it to buy some gum and low and behold, they took it! Although the clerk did look at it strangely, she eventually accepted it as legal tender. I was worried there for a minute.

Haha OK funny man, I was responding to the thread starters question "Is the heat a serious concern anyway?". As my iPhone overheated it did not get damaged so in conclusion, as per my opinion, even if the iPhone is too hot to touch the electronics inside do not get damaged.
