The iPhone 15 Plus gives you a larger 6.7-inch display; the iPhone 17 Pro is smaller but adds a newer chip, three 48MP rear cameras, faster USB transfers and a higher Apple-rated video playback figure. PhoneArena’s reported U.S. launch prices show a $200 gap, but compare carefully: the 15 Plus starting price covered 128GB, while the 17 Pro starting price covered 256GB. Those are historical launch prices, not current offers.

Which phone has the better screen and size?
The iPhone 15 Plus is the choice for a larger viewing area: its 6.7-inch OLED display is 0.4 inches larger by the stated display class than the 17 Pro’s 6.3-inch-class screen. It is also 5 g lighter, at 201 g versus 206 g. Choose the Plus if reading, video or a spacious interface matters more than carrying a narrower phone; the Pro is the more compact option, but not the lighter one.

How do their performance and connections differ?
Chip generation
Apple lists the A16 Bionic in the 15 Plus and A19 Pro in the 17 Pro. That makes the 17 Pro the newer-generation device, but the specifications alone do not establish how much faster it will feel for a particular app or workload.
#1 Best Overall
- This phone is unlocked and compatible with any carrier of choice on GSM and CDMA networks (e.g. AT&T, T-Mobile, Sprint, Verizon, US Cellular, Cricket, Metro, Tracfone, Mint Mobile, etc.).
- Please check with your carrier to verify compatibility.
- When you receive the phone, insert a SIM card from a compatible carrier. Then, turn it on, connect to Wi-Fi, and follow the on screen prompts to activate service.
- The device does not come with headphones or a SIM card. It does include a generic (Mfi certified) charger and charging cable.
- Tested for battery health and guaranteed to have a minimum battery capacity of 80%.
USB file transfers
The 15 Plus USB-C port supports USB 2 transfer speeds up to 480 Mb/s. The 17 Pro supports USB 3 up to 10 Gb/s when paired with a compatible USB 3 cable. That distinction matters most when moving large files over a wired connection; the maximum is a port capability, not a promise that every transfer will reach that rate.
What camera advantages does the 17 Pro offer?
The 15 Plus has a dual rear-camera system with a 48MP main camera and a 12MP ultra-wide camera. The 17 Pro has three 48MP rear cameras and adds professional video options including ProRes RAW and Apple Log 2. On listed hardware and features, the 17 Pro is the stronger fit for varied focal lengths, zoom flexibility and advanced video workflows. The specification comparison does not establish a controlled image-quality result for every scene.
Rank #2
- This phone is unlocked and compatible with any carrier of choice on GSM and CDMA networks (e.g. AT&T, T-Mobile, Sprint, Verizon, US Cellular, Cricket, Metro, Tracfone, Mint Mobile, etc.).
- Please check with your carrier to verify compatibility.
- When you receive the phone, insert a SIM card from a compatible carrier. Then, turn it on, connect to Wi-Fi, and follow the on screen prompts to activate service.
- The device does not come with headphones or a SIM card. It does include a generic (Mfi certified) charger and charging cable.
- Tested for battery health and guaranteed to have a minimum battery capacity of 80%.
Which has longer battery life?
Apple rates video playback at up to 26 hours for the iPhone 15 Plus and up to 33 hours for the iPhone 17 Pro. These are manufacturer estimates based on Apple’s test conditions, so actual runtime varies with settings, signal, apps and use. Apple Ireland’s standardized product information separately lists 45 hours per cycle for iPhone 15 Plus model A3094 and 47 hours per cycle for iPhone 17 Pro model A3523; these regional label figures use a different measure and should not be read as equivalent to the video-playback estimates. See Apple Ireland’s iPhone comparison information.
What is the price difference?
PhoneArena reports the following U.S. launch MSRP figures. They are historical launch prices, not verified current street prices.
Rank #3
- This phone is unlocked and compatible with any carrier of choice on GSM and CDMA networks (e.g. AT&T, T-Mobile, Sprint, Verizon, US Cellular, Cricket, Metro, Tracfone, Mint Mobile, etc.).
- Please check with your carrier to verify compatibility.

| Storage | iPhone 15 Plus launch MSRP | iPhone 17 Pro launch MSRP |
|---|---|---|
| 128GB | $899 | Not offered at this listed launch tier (PhoneArena) |
| 256GB | $999 | $1,099 |
| 512GB | $1,199 | $1,299 |
| 1TB | Not stated (PhoneArena) | $1,499 |
The headline $200 difference compares the 15 Plus 128GB launch price of $899 with the 17 Pro 256GB launch price of $1,099, so it is not a same-storage comparison. At the listed matching capacities, the historical MSRP gap is $100 at both 256GB and 512GB. PhoneArena’s comparison is at its iPhone 15 Plus and iPhone 17 Pro specs page.
Current prices depend on seller, storage, condition, carrier financing and region; no live retailer price is established here. For a used, refurbished or remaining-stock 15 Plus, verify condition and warranty, and compare it with the exact storage and condition of the 17 Pro offer.
Rank #4

Check SIM compatibility before buying
The iPhone 17 Pro is eSIM-only. Apple’s specifications list a physical SIM tray for iPhone 15 Plus models sold outside the United States, reflecting regional variation. Before importing either phone or switching, confirm the exact regional model and that your carrier supports its SIM or eSIM configuration.

Quick Recap
Which one should you choose?
- Choose iPhone 15 Plus if you prioritize a larger screen and can find it at a meaningfully lower current price in suitable condition.
- Choose iPhone 17 Pro if you need the additional camera hardware and video formats, faster wired file transfers, newer-generation chip or higher Apple-rated video playback estimate.
- Keep your iPhone 15 Plus if it meets your needs; the listed differences do not make upgrading worthwhile for every owner by themselves.
