iPhone 15 vs iPhone 13
Design & Build – Subtle But Meaningful Changes
At first glance, the iPhone 13 and iPhone 15 look nearly identical with flat aluminum frames and 6.1-inch displays. But look closer:
- iPhone 13 still has the classic notch.
- iPhone 15 features the Dynamic Island, borrowed from the Pro models.
- iPhone 15 also replaces Lightning with USB-C, making it compatible with modern chargers.
For many, these two design shifts alone are worth considering the upgrade.
Display – Still 6.1″, But Better Experience
Both phones use Super Retina XDR OLED displays:
- Same resolution and size (6.1″)
- iPhone 15 has higher peak brightness (up to 2000 nits outdoors)
- Dynamic Island brings new functionality like music controls, timers, and notifications
No change in refresh rate (still 60Hz), but the brightness and UI tweaks make the iPhone 15 feel fresher.
Performance – A16 vs A15 Bionic
- iPhone 13: A15 Bionic (5-core GPU)
- iPhone 15: A16 Bionic (same as iPhone 14 Pro)
In real-world use, both are fast, but A16 is more power-efficient and better for high-end tasks like gaming, video editing, and AI features coming in iOS 18.
Camera – This is Where It Gets Interesting
- iPhone 13: 12MP main + 12MP ultrawide
- iPhone 15: 48MP main + 12MP ultrawide
Upgrading to the iPhone 15 means:
- Sharper daytime photos
- Better low-light performance
- 2x optical-quality zoom crop using the 48MP sensor
This alone might justify the switch if you love mobile photography.
Battery & Charging – Small Wins
- Battery life is fairly close: ~1 day of normal use
- iPhone 15 supports USB-C, which is faster and more universal
- Lightning accessories won’t work, but USB-C opens up future compatibility
Software Support & iOS 18 Readiness
- iPhone 13 will support iOS 18, but iPhone 15 will likely get updates up to iOS 22+ (around 2029)
- iPhone 15 is more future-proof for AI features and processing power
