Design
Colors and Build
The iPhone 15 is available in soft pastel shades, while the iPhone 16 introduces more vibrant options like Midnight Blue and Coral Pink. Both models retain the aluminum and glass build, but the iPhone 16 features a stronger Ceramic Shield, claimed to be 50% more durable than before, offering better drop protection.


Camera Module
The camera layout has seen minor aesthetic updates. While both feature dual-camera setups, the iPhone 16’s module has a slightly larger lens size, adding a more prominent appearance.
Buttons and Functionality
The iPhone 16 introduces the Action Button to non-Pro models. This button can be customized for shortcuts like opening the camera, starting voice memos, or triggering accessibility options. Additionally, the Capture Button on the iPhone 16 provides extra functionality, such as capturing photos or switching between photo and video modes. This button now replaces the static side button of the iPhone 15.

Display
Both the iPhone 15 and iPhone 16 feature 60Hz Super Retina XDR displays with a peak brightness of 2000 nits. However, the iPhone 16 supports a new low-brightness setting of just 1 nit, making it more comfortable to use in dark environments.
Speakers
The iPhone 16 has slightly better speakers. Voices sound clearer, and bass tones are richer, making it an upgrade for users who frequently watch videos or listen to music without headphones.
Charging and Battery Life
Charging Speeds
Both models feature USB-C 2.0 (limited to 480 Mbps for data transfer). However, the iPhone 16 introduces improved wireless charging speeds of up to 25W via MagSafe, provided you use Apple’s new high-wattage charger. Wired charging has also increased to 45W, reducing the charging time significantly compared to the iPhone 15.
Battery Life
The iPhone 16 boasts a 6.34% larger battery, which translates to approximately 30 minutes more usage under heavy conditions.
Performance
The iPhone 15 is powered by the A16 Bionic chip (4nm), while the iPhone 16 is equipped with the A18 Bionic (3nm).
Benchmark Results


- CPU Performance: The A18 scores 25-30% higher in multi-core benchmarks, thanks to its more efficient architecture and better thermal management.
- GPU Performance: Graphics benchmarks show a 34% improvement, making the iPhone 16 an ideal choice for gamers or creators.
Apple Intelligence

Another major difference between the iPhone 15 and the iPhone 16 is the introduction of Apple Intelligence. While the iPhone 15 lacks this feature, the iPhone 16 takes user experience to the next level with its advanced AI capabilities.
Why Does It Matter?
In short, Apple Intelligence is designed to save you time and make your phone adapt to your needs, rather than the other way around. For anyone looking to streamline their day-to-day tasks, this feature is a significant upgrade over the iPhone 15.
Cameras
Capture Button
The iPhone 16’s Capture Button can snap photos, switch to video mode, or even quickly start Live Photos. While the iPhone 15 allows photo capture using the volume up button, it lacks these versatile options.
Lens and Features
- Selfie Camera: Both models have a 12MP front camera with f/1.9 aperture.
- Ultra-Wide Camera: The iPhone 16 introduces autofocus, resulting in sharper macro shots and less noise in regular photos.
- Video Recording: The iPhone 16 supports spatial video recording, a feature absent in the iPhone 15.
Connectivity
The iPhone 16 supports Wi-Fi 7, delivering faster speeds and lower latency compared to the Wi-Fi 6 on the iPhone 15.
Audio Mixing
The iPhone 16 includes an Audio Mixing Tool, allowing users to adjust voice clarity, background noise suppression, and ambient sound levels. This is particularly useful for recording or playback in noisy environments.
