The iPhone 18 Pro is larger, heavier, starts with twice the storage, and adds an Always-On display and ProMotion refresh rates up to 120Hz. Apple’s U.S. starting price is $1,199 for 256GB. The iPhone 16 starts at 128GB, but the available sources do not establish its current selling price, so a current dollar difference cannot be calculated reliably.

What changes in everyday use?

Display size and refresh features

The iPhone 18 Pro’s screen measures 6.3 inches diagonally, compared with 6.1 inches on iPhone 16. Both are OLED displays rated at 460 pixels per inch. The Pro model adds Always-On functionality and ProMotion, which supports refresh rates up to 120Hz; the iPhone 16 specifications cited here do not list those features.

Storage and physical size

The iPhone 18 Pro’s entry configuration has 256GB, while iPhone 16 starts at 128GB. That makes the starting configurations unequal for a price comparison. The Pro is also 41g heavier (211g versus 170g), a tangible trade-off if a lighter phone matters to you.

#1 Best Overall
Yojaro 4Pack Silicone Suction Phone Case Mount, Silicon Adhesive Smartphones Stand Sticky, Hands-Free Phone Accessories Holder for Selfies and Videos (Black & White & Translucent & Light Pink)
  • 【Strong Adsorption】The inspiration of the silicone phone suction case comes from the adhesive force of the octopus. Each suction cup phone mount is 3.15 inches long and 2.17 inches wide, with 24 independent suction cups providing a stronger and more stable suction force, so you don't have to worry about your phone falling during use.
  • 【Back of Phone Suction Grip】Remove the adhesive film on the phone suction cup and stick it on the phone case. You can then fix the phone on any smooth surface, which is very convenient. (The phone suction cup cannot be removed and reused after being attached to the phone case. It is recommended to attach it to a regular phone case, not a valuable one.)
  • 【Widely Used】Our non-slip silicone phone sticky grip mount attaches to almost any flat phone case and make it compatible with common mobile phones such as iPhone and Android.You can shoot, watch videos or video calls in the kitchen, gym, dance studio, bathroom and other places.
  • 【Capture the Wonderful Picture】Whether you are a TikTok creator or just like to share videos and photos, this phone suction cup can help you hands-free capture wonderful videos and photos for sharing with friends.
  • 【Note】You can fix the phone suction cup on a smooth surface such as a mirror or glass. If necessary, wipe the suction cup with a damp cloth to obtain stronger suction. Before releasing your hand, make sure the phone is firmly fixed. (Not applicable to rough walls, wooden surfaces, and other uneven surfaces)

Chip and camera

Apple lists an A20 Pro in iPhone 18 Pro and an A18 in iPhone 16. The listed core configurations differ, but without comparative benchmark results they should not be translated into a specific percentage or claim about real-world speed. Apple’s launch announcement identifies a 48MP Fusion main camera with variable aperture for iPhone 18 Pro. That description is Apple’s product claim, not an independent camera test; the comparison details here do not establish the corresponding iPhone 16 camera specifications.

How much more does iPhone 18 Pro cost?

Apple’s U.S. reference price for iPhone 18 Pro begins at $1,199 for 256GB. A current iPhone 16 price is not established by the available pricing information, so there is no supported current dollar difference to report. Apple’s listed starting price also does not tell you what a particular retailer or carrier will charge.

Apple EarPods Headphones with USB-C Plug, Wired Ear Buds with Built-in Remote to Control Music, Phone Calls, and Volume
  • SUPERIOR COMFORT — Unlike traditional circular ear buds, the design of EarPods is defined by the geometry of the ear. Which makes them more comfortable for more people than any other ear bud–style headphones.
  • HIGH-QUALITY AUDIO — The speakers inside EarPods have been engineered to maximize sound output and minimize sound loss, which means you get high-quality audio.
  • BUILT-IN REMOTE — EarPods with USB-C plug also include a built-in remote that lets you adjust the volume, control the playback of music and video, and answer or end calls with a pinch of the cord.
  • COMPATIBILITY — Works with all devices that have a USB-C port.
  • INTEGRATED MICROPHONE — A built-in microphone precisely captures your voice while you’re on the phone, taking a FaceTime call, or summoning Siri — so you’re always heard loud and clear.

For a meaningful comparison, match the storage capacity and check both phones in the same country, condition, and sales channel. Also confirm whether each device is unlocked or carrier-specific and whether the displayed amount depends on a trade-in, installment plan, or carrier credits. Treat conditional credits separately from the outright price.

Is iPhone 18 Pro worth upgrading from iPhone 16?

The specifications make the iPhone 18 Pro the more feature-rich option: it has the larger screen, Always-On and up-to-120Hz ProMotion, a newer Pro chip, a higher starting storage tier, and Apple’s announced variable-aperture 48MP Fusion main camera. It is also heavier, and its $1,199 U.S. entry price is for 256GB. Whether upgrading is worthwhile depends on how much you value those differences and the actual condition-matched price you can get for each phone; the available facts do not establish a current price gap or measured performance advantage.
