@03a95182 I”m never surprised by heat issues within the first 3 days or so. I have been experiencing odd issues thereafter though. After morning routine (email, messages, notification checks) I’ll typically set my iPhone on my desk for a period of time between 40 to 60 min. On 4 subsequent mornings (not every one) after picking it back up it has been quite warm,  more so than expected. 

I’m guessing there’s some fine tuning to be done and I don’t have Instagram on this phone currently. /1 

 @03a95182 Also, I have experienced zero issues when charging with either a cable or via MagSafe./end
