iPhone 16 Pro vs iPhone 15 Pro vs Buying Used in 2025: What’s the Smartest Upgrade for UK Shoppers?
The upgrade question in 2025
Apple has released the iPhone 16 Pro lineup with new performance improvements and a refreshed camera system. But many UK buyers are questioning whether paying full price for the latest model is worth it when the iPhone 15 Pro and even earlier models are still delivering excellent performance.
With used iPhone prices dropping in the UK, the real question is simple.
Should you buy the iPhone 16 Pro, choose the iPhone 15 Pro, or save money by going for a high quality used model?
Here is a clear comparison to help you decide.
iPhone 16 Pro overview
The iPhone 16 Pro focuses on four key upgrades.
• A18 Pro chip for faster AI processing
• Improved thermal design for better sustained performance
• Upgraded 48 MP main camera with enhanced low light performance
• Slimmer bezels and slightly larger display area
These updates are meaningful, but the overall experience still feels similar to the iPhone 15 Pro for most everyday users.
iPhone 15 Pro overview
The iPhone 15 Pro remains one of Apple’s strongest releases.
• A17 Pro chip still delivers flagship performance
• Excellent battery optimisation
• Strong camera system with ProRAW and improved video stabilisation
• Lighter titanium body
For many users, the difference between the 15 Pro and 16 Pro is not dramatically noticeable in day to day use.
Performance comparison
Speed
Both phones are extremely fast. The A18 Pro is only slightly ahead in real world usage such as gaming, social apps, or multitasking.
Battery life
Apple claims small improvements with the iPhone 16 Pro, but tests show both models lasting nearly the same through a full day.
Cameras
The iPhone 16 Pro offers clearer low light shots and slightly better video processing. However, the iPhone 15 Pro already delivers professional level results that are more than enough for most users.
Design
Both use a titanium frame. The iPhone 16 Pro is marginally lighter with thinner bezels, but the difference is subtle.
Why many shoppers are choosing used iPhones in 2025
Because new phones are increasing in price every year in the UK, many buyers are now moving towards used devices for better value. A used iPhone 15 Pro or iPhone 14 Pro can give you top level performance at a much lower cost.
Benefits of buying used include:
• Significant savings compared to buying new
• Strong performance even in older flagship models
• Lower environmental impact
• Reliable quality when purchased from a trusted store like BGadgets
Best used alternatives to the iPhone 16 Pro
If you want premium performance without paying premium prices, here are the best used iPhone picks for 2025.
iPhone 15 Pro
Often hundreds of pounds cheaper than new with nearly identical performance.
iPhone 14 Pro
Excellent camera system and strong battery life. A great balance between cost and capability.
iPhone 13 Pro
Still powerful for gaming, photography, and daily use. The most value friendly choice for many UK shoppers.
Final verdict
If you want the absolute newest features, the iPhone 16 Pro is a strong device. But if you want value, the iPhone 15 Pro offers nearly the same experience for a lower cost. And if you want to save even more, buying a high quality used iPhone 14 Pro or 13 Pro remains the smartest choice in 2025.
UK shoppers looking for the best balance between performance and price will find the best deals in the used iPhone market.
