Yeah I’ve noticed home/Lock Screen at the top of battery usage daily as well. The speakers are more immersive!Same for me on my 12.
Can’t speak for a 14 but it seems that the always on screen is very bright and needs tweaking. So could be the culprit.
Big up connectivity though. See iPhone 13 pros on 1 bar LTE and 14 pro 3 bars.
This guys done a pretty comprehensive comparison. The speaker 😍
