iPhone 15 • Locked T-Mobile vs OnePlus 12 • Unlocked

The iPhone 15, released in September 2023, and the OnePlus 12, which saw its global launch in January 2024, represent distinct approaches to the modern smartphone experience. While the iPhone 15 operates on Apple's iOS ecosystem, the OnePlus 12 runs on Android with OxygenOS. Key differentiators between these two devices include their operating systems, display technologies, and camera philosophies.

When considering the long-term usability of a smartphone, factors like software support, physical resilience, and ease of repair are crucial. Both devices offer robust designs, but their ecosystems approach longevity differently.

• Software Support: The iPhone 15, running iOS, typically receives major software updates for five to six years from its release, with Apple recently stating the iPhone 15 series can retain 80% of its battery capacity after 1000 charge cycles, double previous estimates. The OnePlus 12, based on Android, generally receives three to four years of major Android version updates and an additional year of security patches.
• Physical Durability: The iPhone 15 features a Ceramic Shield front cover and a color-infused glass back within an aluminum frame, offering IP68 dust and water resistance. The OnePlus 12 is protected by Corning Gorilla Glass Victus 2 on its display and carries an IP65 rating for dust and water resistance.
• Repairability: Initial assessments for the iPhone 15 indicated a repairability score of 4 out of 10, though this was later boosted to 7 out of 10 due to software changes in iOS 18 that improved part calibration. Information on the OnePlus 12's repairability score is less widely available, but its design with curved glass may present challenges for some repairs.
