What is the downside of the iPhone 15?

Downsides of the iPhone 15 include issues related to overheating, decreased thermal tolerance caused by lightweight materials and design choices leading to reduced heavy-use capability with the risk of damage shown in drop tests, concerns about software-based (but potentially addressable) fingerprint attraction, and some reliability and usability complications associated with the transition to iOS 15. Additionally, users have observed occasional sluggish performance in terms of slow or choppy experiences, often connected to interacting with the freshly rolled-out iOS 17 on the iPhone 15. Nonetheless, some technical challenges like overheating and certain software glitches can be alleviated via software updates issued by Apple.
