iPhone 15 vs iPhone 17

Short answer: buy the iPhone 17 if you want a 120Hz ProMotion screen with Always-On display, the much faster A19 chip, a 48MP ultra-wide, an 18MP Center Stage selfie camera, 40W charging, Apple Intelligence and 256GB base storage. Buy the iPhone 15 if you want a reliable, compact iPhone with Dynamic Island, USB-C and a 48MP main camera at a lower cost. The iPhone 17 is the bigger upgrade of the two generations.

Updated 11 November 2026

Design and build

Both have an aluminium frame, a glass back and IP68 water resistance. The iPhone 17 has a slightly larger 6.3 inch body and weighs about 177 g, against 171 g for the 6.1 inch iPhone 15. The iPhone 17 uses Ceramic Shield 2 on the front, which Apple says is more scratch resistant.

The iPhone 17 also has the Action Button and the Camera Control button on the side. The iPhone 15 keeps the older Ring/Silent switch and has no Camera Control.

Display

This is the most visible upgrade. The iPhone 17 has a 6.3 inch LTPO OLED at 1206 x 2622 with ProMotion from 1Hz to 120Hz, Always-On display and up to 3000 nits outdoors. The iPhone 15 has a 6.1 inch OLED at 1179 x 2556, 60Hz only, with up to 2000 nits.

Scrolling on the iPhone 17 is far smoother, and the brighter panel is easier to read in summer sun. Both have Dynamic Island.

Performance and chipset

The iPhone 17 uses the A19 on a 3 nm process; the iPhone 15 uses the A16 Bionic on 4 nm. The A19 is much faster in CPU and graphics, handles heavy games for longer and supports Apple Intelligence, which the iPhone 15 does not.

The iPhone 17 also has Apple's N1 wireless chip with Wi-Fi 7, against Wi-Fi 6 on the iPhone 15. For WhatsApp, banking and social apps the iPhone 15 is still smooth, but the 17 will age better.

Cameras

Both have a 48MP main camera. The iPhone 17 upgrades the ultra-wide from 12MP to 48MP, giving sharper wide shots and better macro photos. The front camera jumps from 12MP to an 18MP Center Stage camera that can take wide group selfies and landscape selfies while you hold the phone upright.

Both record 4K 60fps Dolby Vision video. For group photos and video calls, the iPhone 17 is clearly better.

Battery and charging

The iPhone 17 has a 3692 mAh battery against 3349 mAh on the iPhone 15, and the more efficient A19 and LTPO screen stretch it further. Apple rates the iPhone 17 at up to 30 hours of video playback against 20 hours for the iPhone 15.

Charging is much faster on the iPhone 17: up to 40W wired (about 50% in 20 minutes with a suitable adapter) and 25W MagSafe with Qi2.2. The iPhone 15 does about 50% in 30 minutes wired and 15W MagSafe. That speed helps a lot between load shedding slots.

Software and updates

The iPhone 15 launched with iOS 17 in September 2023 and the iPhone 17 with iOS 26 in September 2025, so the iPhone 17 should get about two more years of iOS updates. It also supports Apple Intelligence; the iPhone 15 does not.

Non PTA and SIM notes in Pakistan

Our iPhone 15 units are slightly used Non PTA phones with 100% battery health, and our iPhone 17 is a Non PTA slightly used unit with 100% battery health. Both have original IMEIs. A Non PTA iPhone is not registered with PTA's DIRBS, so a local SIM works only for a limited time unless you register it and pay the PTA tax. Wi-Fi and every other feature work normally. Read our Non PTA guide (What Is a Non PTA Mobile? Everything You Should Know).

International iPhone 15 units have a nano-SIM plus eSIM. The iPhone 17 is nano-SIM plus eSIM or eSIM only depending on the country variant, so confirm the variant before you order.

Who should buy which

Buy the iPhone 17 if you want a newer phone, 120Hz, faster charging, better selfies, Apple Intelligence and the longest update life.

Buy the iPhone 15 if you want a proven iPhone with USB-C and Dynamic Island at a lower cost and you are fine with a used unit in good battery health. The current price of each model is shown on its page.
