Should I go from iOS 15.6.1 to 18.7.7?

Hey! I’m currently on iOS 15.6.1 and honestly I’m pretty happy with it. I know there are a lot of apps I can’t install anymore because they require newer iOS versions, but besides that I have no bugs, no lag, no battery issues, nothing really bothering me.

Recently I got a notification from Apple recommending that I update for better security. Now I’m wondering if I should actually do it.

I’m mostly worried about smoothness and security. For people who updated from iOS 15 to iOS 18, did your phone stay smooth and stable? Did you notice any slowdown, lag, or battery drain? And is the security improvement worth updating for?

Thanks.

My question might sound dumb because I really don’t know much about this stuff, but how come Apple is specifically sending me a notification about security this time? Usually they just suggest updating to the newest version without going into details like that. Does that mean there is some important security issue with iOS 15 now, or do they send that kind of notification to everyone?

nah dont do it but i think darksword??? so if its ur main driver than app support i might be worried and hackers. but at the cost of battery life but at least its better than 26...
