The iPhone 15 is still a very reliable device after several months of normal use. It has a few key weak points according to user comments. The A16 Bionic chip performance is still very fast, so it can easily run even future software (OS 26). However, the 60Hz display becomes more and more a disadvantage if compared with the 120Hz newer models. Battery health is generally good, with one of the standard cycles being around 95- 99% after 200+ cycles. Still, some high usage users report slight heating when using the camera for a long time or during quick charging. The biggest long-term disadvantage is the absence of support for Apple Intelligence, which leaves the iPhone 15 slightly behind the iPhone 15 Pro or newer base models.
