We know the iPhone 6S will get three levels of Force Touch, which is one more than the Apple Watch and MacBook. But that's not all that's changing. It now seems the screen could be in for a bump in resolution too.
According to a leak from Weibo user @KJuma, the 4.7-inch iPhone 6S will have a resolution of 1,125x2,000 pixels, giving it a pixel per inch count of 488ppi. Which would be quite a step up from the iPhone 6's resolution of 750x1,134, and 326ppi.
The iPhone 6S Plus is also said to be in line for a significant jump in resolution, from 1,080x1,920 pixels (401ppi) to 1,242x2,208 (466ppi).
Both screens are rumoured to stay the same size. Indeed, both phones are expected to look almost identical to their predecessors, though they might be slightly fatter to prevent another bendgate.
The Chinese site also claims to have the iPhone 6S's specs via a benchmark from Geekbench. It claims the handset will have a 1.8GHz A9 SoC chipset with 2GB of RAM.
Of course these are unsubstantiated, so take it all with a pinch of salt. But there's not long until the rumours are dispelled and we know for sure.
Apple will unveil both handsets plus a new Apple TV and possibly the iPad Pro tomorrow evening. We'll bring you all the news as it happens.
