Is the iPhone 15 worth the upgrade?

So, I've been using the iPhone 13 for a while now and it's been pretty solid. But with the iPhone 15 just released, I'm wondering if it's really worth the jump. The new design and enhanced camera features look amazing, but is it enough to justify the cost? I know some of you tech enthusiasts out there might have already taken the plunge. What's your take? Also, how are the new battery life and performance compared to older models? Any quirks or things that might not be highlighted in the flashy ads? For those who've upgraded, are you noticing a big difference in everyday use? Would love to hear some real-world experiences before I make up my mind! 🤔📱
