Chinese site Feng has spoken with sources familiar to Apple's supply chain and has found the screen resolutions on the 6S Plus is set for a serious upgrade.
The sources claim the standard iPhone 6S is set to stick with the 4.7-inch Full HD resolution screen while the iPhone 6S Plus will have a 5.5-inch display that's now in 2K.
What about battery?
That's a big ask of an iPhone and having such a high resolution display suggests there may be some serious issues with battery life.
The site also found that both iPhone 6S models will feature Force Touch, a rumour we've heard before, and the cheapest versions will start off on 32GB.
No word on the rest of the storage options, but we've rounded up a few other iPhone 6S rumours here.
