Having worked in the field of technology for over a decade as well as an active iOS user, I was excited to test out the new features in iOS 18. But after only a week, I'm bored and I really think iOS 18 sucks. On latest smartphones, what was once perfect and smooth experience has been replaced by ongoing issues, frequent app crashes, and slow performance. For its ambition, the UI improvements appear rushed and difficult to use. There has also been a major reduction in battery life. Sincerely, I'm thinking of upgrading since I miss iOS 17's reliability and simplicity. This update simply falls below of Apple's typical level of quality.
