Should you upgrade from the iPhone 15 Plus?
Your 15 Plus still does the job. The 18 Pro is a nice-to-have.
- It is 3 years old.
What the iPhone 18 Pro adds over the iPhone 15 Plus
- A20 Pro chip, 4 generations newer than your A16.
- 36 hours of video playback, against 26 on yours (both with a new battery).
- Apple Intelligence and the new Siri, which need an iPhone 15 Pro or later.
- A 120Hz screen instead of 60Hz, so scrolling is noticeably smoother.
- A telephoto lens, which your phone does not have.
In the United States, an iPhone 18 Pro 256GB costs $1,199. After selling an iPhone 15 Plus it costs $863 to $919. Your own result depends on battery health, condition and where you sell, so run the tool for your phone.
If the battery is the problem, a battery replacement at an Apple Store or authorised repair shop costs far less than a new phone.
