One thing I have noticed and I’ve reported to Apple in the past, is that my 16 Pro used to get noticeably warm when editing photos in the app and draining battery.
Editing some photos from today and it’s nowhere near as warm as it has been since using iOS 18.6 from the early betas.
On top of this, placebo or not this version feels even more polished! Everything just appears to be smoother and faster on my 16 Pro.
Plugged in my Apple 30w charger this morning and it’s barely getting warm.
Have yet to come across the random keyboard lag.
As has been stated further up in here, 18.6.1 is 4 builds newer. Apple have definitely tweaked 18.6.1 and not just added the blood oxygen feature.
