Hi, bro how are you, im using 14 Pro Max still I haven’t updated the 18.1 still I’m using 17.7.1. I’m scared to update bro 
Please suggest me, bro I bought it on October 25, 2022, and now my battery percentage is 87
Good bro. thank you. hoping you too. iOS 18.1 feels stable for now. there are minor bugs bro. but so far not much negative reviews. you may update if you are ready to experience iOS 18 features bro. else wait for some more time and next month iOS 18.2 is coming. You may update after that too.
