Safe Battery Temperature?

[exempli_gratia]

What's a safe battery temperature for the S8/S8+, to prevent battery wear/dammage?

I see 105 when using on a hot day, for instance.

Wireless charging seems to heat up more than wired.

Any concerns?

If you can't hold your hand on it, it's too hot.

I believe the phone will turn off when it gets too hot at at least warn you. I don't think 105 is unsafe. My note 7 and note 5 would get to almost 120 when using the VR.

105 isn't a problem. As you go hotter though, you will decrease the battery life.
