   You are correct because the causes are so mundane that the only way Apple   
   could have not known about (charging & Instagram & common games) causing   
   the iPhone overheating is that Apple thought they didn't need to test it.

   At least that Apple failure to test had a simple hardware add-on fix.

   It had to be hardware because Apple had the same batteries in other iPhones   
   that didn't need to be throttled after only a short time in normal use.

   Why is the throttling code that Apple introduced as an emergency workaround   
   still in the software if the problem has been fixed with the added PMIC?

   The replacement battery was like putting a bandaid on a broken limb.

   Can you think of any other software solution than reducing performance?
