iPhone 15 vs iPhone SE (2020)

The iPhone 15, released in September 2023, and the iPhone SE 2020, launched in April 2020, represent distinct approaches within Apple's smartphone lineup. While both operate on the iOS platform, the iPhone 15 offers a modern, full-screen experience with advanced features, whereas the iPhone SE 2020 provides a more traditional design with a physical home button. These differences extend to their internal components and overall user experience, catering to varying preferences and needs.

When considering the practical lifespan of these devices, several factors come into play, including their release timelines, software support, and physical resilience.

• Release Timeline and Software Support: The iPhone 15, being a much newer device from September 2023, is expected to receive iOS updates for a significantly longer period than the iPhone SE 2020, which was released in April 2020. This means the iPhone 15 will benefit from new features, security patches, and performance optimizations for more years, extending its functional life. The iPhone SE 2020 launched with iOS 13.4 and has received updates up to iOS 26, but its update cycle is nearing its end compared to the iPhone 15, which launched with iOS 17 and is compatible with iOS 26.
• Physical Durability: The iPhone 15 features a Ceramic Shield front cover, offering enhanced drop protection, and is rated IP68 for water and dust resistance, allowing submersion up to 6 meters for 30 minutes. The iPhone SE 2020 has a glass front and back with an aluminum frame and is rated IP67, meaning it can withstand submersion up to 1 meter for 30 minutes. Users seeking greater physical resilience against accidents may find the iPhone 15 more robust.
• Battery Longevity: Apple states that iPhone 15 models are designed to retain 80% of their original battery capacity after 1,000 complete charge cycles, an improvement over previous models like the iPhone SE 2020, which were designed for 500 cycles. This suggests the iPhone 15's battery may maintain optimal performance for a longer duration under typical usage.

The performance capabilities of these two iPhones show a notable generational gap, impacting how smoothly they handle various tasks.

• Processing Power: The iPhone 15 is equipped with a more advanced processor, which translates to faster app loading times, smoother transitions between applications, and more efficient handling of demanding tasks like high-fidelity gaming and video editing. The iPhone SE 2020, while still capable for everyday use, relies on an older generation processor, which may exhibit slower performance with newer, more resource-intensive applications.
• Multitasking and Responsiveness: The iPhone 15 generally offers a more responsive user experience, especially when juggling multiple applications or running complex software. This is partly due to its more efficient processor and potentially optimized software interactions. The iPhone SE 2020 provides adequate responsiveness for general use, but users who frequently switch between many apps or use professional-grade tools might notice a difference.
• Storage Options: Both devices offer various internal storage capacities. The iPhone 15 is available in 128GB, 256GB, and 512GB configurations. The iPhone SE 2020 was available in 64GB, 128GB, and 256GB options. Users with extensive media libraries or numerous applications may find the higher storage tiers of the iPhone 15 more accommodating.

The visual experience differs significantly between the iPhone 15 and the iPhone SE 2020, primarily due to advancements in display technology and design.

• Display Technology and Clarity: The iPhone 15 features a 6.1-inch Super Retina XDR OLED display, offering deep blacks, vibrant colors, and a high contrast ratio, resulting in a more immersive viewing experience. The iPhone SE 2020 has a 4.7-inch Retina HD LCD display, which provides good color accuracy and brightness but does not match the contrast and black levels of an OLED panel.
• Brightness and Outdoor Visibility: The iPhone 15 boasts significantly higher peak brightness levels, reaching up to 2000 nits for outdoor use, making content more legible in bright sunlight. The iPhone SE 2020 has a maximum brightness of 625 nits, which is sufficient for most indoor conditions but can be less visible under direct sunlight.
• Screen Size and Design: The iPhone 15 offers a larger, edge-to-edge display with the Dynamic Island, providing more screen real estate for content consumption and interaction. The iPhone SE 2020 retains the traditional iPhone design with thicker bezels and a physical home button, resulting in a smaller display area relative to its body size.

The camera systems of the iPhone 15 and iPhone SE 2020 reflect different generations of photographic capabilities, with the newer model offering more advanced features.

• Rear Camera System: The iPhone 15 features a dual-camera system with a 48MP main sensor and a 12MP ultrawide lens, enabling higher-resolution photos, improved low-light performance, and a 2x telephoto option through sensor cropping. The iPhone SE 2020 has a single 12MP wide camera, which performs well in good lighting conditions but lacks the versatility and advanced computational photography features of the iPhone 15.
• Photography Features: The iPhone 15 benefits from features like Photonic Engine, Smart HDR 5, and next-generation portraits with Focus and Depth Control, contributing to more detailed and dynamic images. While the iPhone SE 2020 includes Portrait mode, its capabilities are more limited due to the single lens and older processing.
• Video Recording and Front Camera: Both devices can record 4K video, but the iPhone 15 offers more advanced video features like Cinematic mode up to 4K HDR and Action mode. The iPhone 15 also has a 12MP TrueDepth front camera with autofocus, while the iPhone SE 2020 has a 7MP front camera.
