The new generation of iPhones will use improved circuitry that will support fast-charge technology based on a leaked photo of the smartphone’s logic board.

AppleInsider published the photo shared by Apple leak source @the_malignant on Twitter. Judging from the unconfirmed photos, AppleInsider said the iPhone 7 will support a 5-volt, 2-amp charging, noting that current iPhone chargers are rated at 1-amp.

The rumour has it that the next generation of iPhones will ditch the headphone jack to give way for a second speaker. The Apple smartphone is also rumoured to have dual-camera design for enhanced photography under low light.

While the new iPhones will follow iPhone 6 and 6 Plus’ screen sizes, the new batch has employed touch-sensitive home button that uses haptic feedback.

Apple has not yet announced when it will launch the highly anticipated new iPhone model. However, the company historically unveils their new product lineup every September.

Mark Gurman of Bloomberg reported that a Sept. 7 event is scheduled but Apple is yet to confirm it. Meanwhile, Evan Blass of venturebeat.com claimed that pre-order of the new iPhones will start on Sept. 9 in the US.

The latest iPhone model will run on iOS 10, the latest version of Apple smartphone operating system.

The iPhone was first launched in 2007. Apple CEO Tim Cook announced that the company has sold its one-billionth iPhone unit last month.
