The rumours are rampant as the iPhone 17 series is just a few weeks away from launch. Excitingly, the iPhone 17 Pro's battery design has been made public.
In a major leak, tipster Majin Bu revealed a picture of the iPhone 17 Pro's battery prototype, giving users a sneak peek at the internal architecture of the device.
It looks like the leaked image depicts a steel-encased battery, a design feature that might improve the device's functionality and user experience.
The leaked material claims that the battery of the device will have an L-shaped steel enclosure, a design element that should improve heat dissipation and give the phone's chassis more structural strength.
Interestingly, it is said that the steel casing can be combined with other useful parts, such as Apple's exclusive MagSafe charging coil.
Additionally, the design of the battery is said to differ slightly depending on the market.
The US version is anticipated to have a wider battery, in line with the device's e-SIM-only configuration, while the Chinese version has a narrower battery with a longer L-shaped cutout to accommodate the physical SIM tray slot.
Notable is the steel casing's welded edge, which is anticipated to make battery replacements simpler by utilising electrically induced adhesive debonding technology.
This creative method speeds up the repair process by making it possible to remove the battery with ease after a tiny current is run through the adhesive.
While it is unclear if Apple will eventually use this design for the iPhone 17 Pro, the information that has been leaked offers an intriguing look into the company's continuous attempts to improve the functionality and user experience of its product.
The iPhone 17 Air, iPhone 17, and iPhone 17 Pro Max are expected to be released next month, along with the iPhone 17 Pro.
