The iPhone 15 Pro Max is expected to have a smaller battery capacity than previously rumored, but the use of a 3nm fabrication process and stacked battery technology could still improve battery life by up to 20%.
The upcoming iPhone 15 Pro Max will feature a lighter titanium chassis, larger displays, improved battery life, faster wireless charging, and upgraded cameras.
Apple has tested multiple storage and RAM configurations for the iPhone 15 Pro, including options from different vendors and two RAM configurations, but it is unclear which ones will be used in the final production units. The iPhone 15 Pro will also feature an upgraded A17 SoC, a titanium frame, USB-C, and a periscope zoom lens.
The iPhone 15 Pro and iPhone 15 Pro Max have a more repairable internal design, featuring a removable back glass panel, which may result in lower repair fees for cracked back glass.
The iPhone 15 and iPhone 15 Pro models have a new battery health setting that limits charging to 80% at all times, separate from the Optimized Battery Charging feature, in order to improve battery lifespan.
The iPhone 15 is found to have a similar design to the iPhone 14 in terms of repairability, with the ability to be opened from both the back and front, but its internal chassis architecture and removal of the display for certain repairs make battery switches riskier; meanwhile, the increase in battery capacity is deemed insufficient, and the titanium shell raises concerns about cost, difficulty in working with, and sustainability.
The iPhone 15 and iPhone 15 Pro represent the culmination of years of iteration, featuring refined designs, improved cameras, and powerful specifications, indicating that we may have reached the peak of smartphone technology.
The iPhone 15 Pro has been reported to have overheating issues and a swollen battery, potentially posing a fire hazard and hindering its status as the best phone of 2023.
The iPhone 15 Pro Max is a significant upgrade from its predecessor, with improvements in design, camera capabilities, and features such as the Action Button and USB-C, making it one of the best smartphones on the market.
The iPhone 15 Pro Max is Apple's most powerful iPhone to date, featuring an A17 Pro chipset, console-grade gaming capabilities, a new telephoto lens, USB-C charging, and an Action button, making it worth the upgrade from the iPhone 14 Pro Max.
The iPhone 15 has outdated and underwhelming specs, including a lack of an always-on display, low refresh rate, and the use of a previous generation chipset, making it difficult to recommend over other comparable Android flagship devices or even the iPhone 14 Pro.
