The LG G5 and Samsung's S7 have better specs in a number of areas: the G5 has higher camera megapixel ratings (as well as dual rear-facing cameras); both have a much better screen resolution; battery capacities are greater; and processing power, thanks to more RAM and a quad-core processor (the iPhone 6s and 6s Plus have dual-core chips).
Specs can be deceptive, and what really matters is the user experience: the pleasure and usefulness a device offers.
The quality of a photograph, for example, is about a lot more than the camera's megapixel rating, as we discuss in our article about the megapixel myth. Battery life is quite obviously influenced by battery capacity, but also by the demands placed on the battery by the rest of the hardware (and this is likely to be higher if you have an exceptionally high screen resolution) and how optimised the OS is to the device. Screen resolution beyond a certain point is overkill, because the human eye has long since stopped being able to make out the individual pixels. And the iPhone 6s is clearly powerful enough to run anything on the App Store.
Samsung Galaxy S7
But while specs don't tell the whole story, they can't be ignored, either. And Apple faces a perception issue, too.
For more thoughts on the areas where the iPhone is perceived to have fallen behind its most famous rivals, and the areas we therefore think it might focus on this autumn, see our comparison reviews: iPhone 6s vs Samsung Galaxy S7 and iPhone 6s vs LG G5.
iPhone 7 specs rumours: LiFi
The latest rumour about the iPhone 7's specs relates to LiFi, a new wireless standard that boasts 100x faster download speeds than conventional WiFi connections. LiFi uses visible light communication (VLC) instead of radio waves like conventional WiFi routers.
iPhone 7 specs rumours: Stacked battery cells
One rumour holds that Apple will take the battery developments it deployed in the12-inch MacBook - whereby contoured, layered battery units are stacked inside the chassis in order to take up every possible inch of space - and use these to squeeze more battery volume inside the iPhone 7.
(According to Wired's write-up, Apple actually claims to adjust its battery contours on a machine-by-machine basis, by photographing the inside of the chassis and modifying the battery stack to fit all the tiny imperfections - which, if it's true, is amazing.)
