Yes, and as a participant the “everyone” includes you.
Now can we get back on topic?
As I said earlier, I have two phones here affected by this (a 6 and 6s) and neither have said their phones are feeling different and neither are newer batteries. The 6 had a new battery a year ago but gets charged several times a day (teenagers) while the 6s had one too and has been more gently treated, but has a newer processor.
I think having the switch will be interesting to see how phones are affected. I’ll have them both test it to see how it performs on and off.
