I never found a solution, and hoped that it would eventually settle down. I think it started running not so hot all the time, but battery consumption remained through the roof to the point where sometimes consumption was almost outrunning its ability to charge. It is without question a consumption issue though (and not faulty battery) not only because of the timing with all the other updates we incurred, but because the battery charges just fine (and quickly) with the phone powered off (which was sometimes required to keep up). Don't know what they did, but they virtually ruined the phone with whatever came down the pipe. After seeing so many relatives have their older iPhones completely tank shortly after an update, we used to somewhat joke about a conspiracy theory that it was the manufacturer's way of getting people to upgrade. Hopefully, that's only a conspiracy theory, but in this case it worked. Operating this way was simply nonsufficient for a business day, so I had to migrate to a new phone rather than burn life minutes possibly with no solution. Unfortunately, had to say good-bye to having an SD card, and I'll hold a grudge for that design change probably forever because I netted nearly zero memory gain with the brand new phone.
