I’ve held off running the iOS 16 beta this time around. I’ve been busy and didn’t want to mess with anything. But now I’m back off holiday I put iOS 16 beta 4 onto my iPhone 13 Mini. In my testing I’ve been pleasantly surprised at how it runs.

Battery was down about 10%, which seems ok to me. It’s not far off iOS 15 in terms of day to day performance.

The only issues I found was the phone got a bit warmer, especially when charging. I also noticed bugs (as you’d expect) with the new Lock Screen functionality.

If you’re worried about battery life on the iPhone Mini models on iOS 16, I wouldn’t worry. Go into it open minded that you’ll experience crashes and your device isn’t going to be as stable and may get a little warmer.
