The iPhone 15 has evolved significantly from the iPhone 14 with the adoption of a USB-C port, a 48MP main camera, and new features like Dynamic Island. However, there are no changes in weight, size, or battery performance.
Differences in Size, Design, and Color
The iPhone 14 and 15 are almost the same size, with no change in ease of holding or weight. However, the iPhone 15 features a "color-infused glass" back design, which gives it a more luxurious look and a smoother feel than the iPhone 14.
The iPhone 15's colors have been refreshed, with more vibrant and soft colors like pink and green. However, popular colors like Midnight, Starlight, and (PRODUCT)RED are no longer available.
If you want a color not available on the iPhone 15, such as Midnight or Starlight, the iPhone 14 is more suitable.
Differences in Camera Performance and Camera Size
One of the biggest differences between the iPhone 14 and 15 is camera performance. The iPhone 15 features a 48MP high-resolution main camera, compared to the iPhone 14's 12MP. This allows for 2x zoom and captures crisp, detailed photos.
It also excels in low-light and backlit conditions, making it highly appealing to those who frequently take photos and videos. Furthermore, the camera bump on the 15 is slightly thinner, improving both design and portability.
Thus, the iPhone 15 offers superior camera performance. If camera performance is a priority, choose the iPhone 15.
Differences in Chip Performance and Battery
The iPhone 15 is equipped with the "A16 Bionic" chip, which was previously used in higher-end models, offering slightly improved processing speed compared to the iPhone 14's A15. However, you are unlikely to notice a performance difference in everyday use. Therefore, it is difficult to compare the iPhone 14 and 15 based on chip performance.
Battery life for both models is "up to 20 hours of video playback," with no significant difference.
It is not possible to compare the iPhone 14 and 15 based on chip performance or battery.
Differences in Ports
The iPhone 15 abolished the Lightning port and switched to a USB-C port. This allows for the unification of charging cables with other Apple products like MacBooks and iPads, as well as small home appliances, which will improve daily convenience. Compared to the Lightning port, it is now possible to transfer more data faster.
On the other hand, the iPhone 14 retains the Lightning port, allowing existing accessories to be used as they are.
Unless you have a particular preference for the port, there's no need to worry about it.
Differences in Price and Cost-Performance
The new iPhone 14 is priced from approximately 85,000 yen, while the iPhone 15 starts at approximately 125,000 yen, a difference of about 40,000 yen. Although there is a performance difference, the iPhone 14 is sufficient for daily use and is appealing to those who prioritize cost-performance. If you are looking for a higher-performance model with features like an improved camera, consider the iPhone 15.
In the used market, the iPhone 14 can be purchased for a lower price of around 65,000 yen, making it recommended for those who prioritize cost.
