What CompareTab says about Apple iPhone 15 vs Apple iPhone 18 Pro
Apple iPhone 18 Pro has clear advantages in memory, battery capacity and display refresh rate over iPhone 15, with 12 GB of RAM versus 6 GB, 256 GB of storage versus 128 GB, a 4056 mAh battery versus 3349 mAh, and a 120 Hz display instead of 60 Hz. It also adds a higher-resolution front camera (18 MP versus 12 MP). Apple iPhone 15, however, is around $400 cheaper, lighter at 171 g versus 211 g, and thinner at 7.8 mm versus 8.75 mm. The main trade-off is iPhone 18 Pro’s extra RAM, storage, battery capacity, smoother display, and higher-resolution front camera versus iPhone 15’s lower price and lighter, thinner build.
