Apple might be implementing fast-charging technology into the next iPhone, which could see the device go from zero to fifty percent in just thirty minutes.

We’ve seen plenty of rumors surrounding the new features coming to the next iPhone, expected to be called the iPhone 7, and it looks like many will come true. Numerous casing leaks have shown us that the device will largely keep the same design as the iPhone 6 and 6s, including their Plus models, but with less antenna bands, and a dual camera on the larger model.

However, a more recent rumor concerns a fast-charging iPhone 7 and arrives via a Twitter account that posts smartphone-based leaks. Citing a source in China, the post includes an image (above) that shows circuits from a new device, alongside the logic board form the 6s. It says the new device will support 5-volt, 2-amp charging – a step up from the iPhone 6s’ 1-amp.

This will put Apple’s smartphone in line with some of its competitors, such as the Samsung Galaxy S7 and S7 Edge. Those devices can reach fifty percent charge in around thirty minutes.

Battery life improvements are often cited as a major desire for smartphone owners, but fast-charging technology is a step in the right direction and will be a big deal for Apple users.

Whether this will come to fruition is unknown – the leaker doesn’t have a long track record for leaks, so its accuracy is uncertain. Nevertheless, it’s a interesting proposition.
