It’s my first iphone (16 model) pls help me understand:
I’m currently on iOS 18.7.2 and haven’t updated yet. I’ve been seeing mixed reviews about iOS 26.5, especially around performance and battery life.

I just want to understand, if I don’t update, will it cause any issues over time like lag, bugs, or app problems? Or is it perfectly fine to stay on iOS 18 for now?

Would appreciate your help.

Edit: updated to 18.7.8
