The iPhone 15 Plus also incorporates a color-infused glass back with a textured matte finish and contoured edges, while the iPhone 13 Pro Max has a matte glass back. Both devices carry an IP68 rating for water and dust resistance, indicating they can withstand submersion in water up to 6 meters for 30 minutes.
• Repairability: While specific repairability scores can vary, both iPhones are designed with Apple's ecosystem in mind. The availability of parts and repair services typically remains strong for several years post-release.

Performance is a core aspect of any smartphone, influencing everything from app responsiveness to gaming experiences and battery efficiency.

• System Responsiveness: The iPhone 15 Plus is equipped with a newer generation processor, which translates to slightly faster app loading times and smoother transitions compared to the iPhone 13 Pro Max. This newer processor also contributes to more efficient power management.
• Multitasking and Demanding Applications: Both devices handle multiple applications and graphically intensive tasks with ease. The iPhone 13 Pro Max, with its powerful processor from 2021, still offers robust performance for most users, including those who engage in mobile gaming or video editing. The iPhone 15 Plus provides a marginal improvement in raw processing power, which may be more noticeable in future demanding applications.
• Storage Options: The iPhone 13 Pro Max was available with storage capacities up to 1TB, catering to users with extensive media libraries or professional content creation needs. The iPhone 15 Plus offers storage options up to 512GB.
• Battery Behavior: The iPhone 13 Pro Max is widely recognized for its exceptional battery life, often providing multi-day usage for many users. The iPhone 15 Plus also offers strong battery performance, with users reporting it comfortably lasts a full day, and often longer, even with heavy use.

The display is a primary interface for smartphone interaction, and both models offer large, high-quality viewing experiences with some key distinctions.

• Display Technology and Clarity: Both the iPhone 13 Pro Max and iPhone 15 Plus feature 6.7-inch Super Retina XDR OLED displays, delivering deep blacks, vibrant colors, and excellent contrast. The resolution is very similar, resulting in sharp text and detailed images on both devices.
• Refresh Rate: A significant difference lies in the refresh rate. The iPhone 13 Pro Max features ProMotion technology, offering an adaptive refresh rate up to 120Hz, which provides noticeably smoother scrolling and more fluid animations. The iPhone 15 Plus has a standard 60Hz refresh rate.
• Brightness Levels: The iPhone 15 Plus offers higher peak brightness for outdoor use, reaching up to 2000 nits, making it easier to view content in direct sunlight. The iPhone 13 Pro Max also provides excellent brightness, with a typical maximum of 1000 nits and peak HDR brightness of 1200 nits.
• Display Features: The iPhone 15 Plus introduces the Dynamic Island, replacing the traditional notch, which integrates alerts and background activities into an interactive area at the top of the display. The iPhone 13 Pro Max retains the notch design.

Both iPhones are capable photographic tools, but the newer model brings advancements in sensor technology and computational photography.

• Main Camera System: The iPhone 15 Plus features an advanced dual-camera system with a 48MP main sensor, which can capture detailed 24MP photos by default and offers a 2x telephoto option through sensor cropping. The iPhone 13 Pro Max has a 12MP Pro camera system, including a dedicated 12MP telephoto lens with 3x optical zoom.
• Low-Light Performance: Both devices excel in low-light conditions, though the iPhone 15 Plus benefits from its larger main sensor and improved computational photography, leading to slightly better detail and color accuracy in challenging lighting. The iPhone 13 Pro Max also delivers strong low-light results, particularly with its larger sensor and wider aperture on the main lens.
• Video Recording: Both models offer high-quality video recording, including 4K at 60 frames per second. The iPhone 13 Pro Max includes ProRes video recording, a feature beneficial for professional videographers. The iPhone 15 Plus offers Cinematic mode for videos with shallow depth of field.
