iPhone 11 battery and lag after iOS 26.4 update

iPhone 11 Performance and Battery Inquiry after Update

"I am using an iPhone 11 and I have recently updated to iOS 26.4.

I am noticing some issues with the battery performance and the device seems to be lagging slightly during normal use. I would like to know if others are facing similar issues on this model or if there are any specific settings I should check to optimize the performance.

Any help or suggestions from the community would be greatly appreciated. Thank you!"
