iPhone 6S review: a very good phone ruined by rubbish battery life

Apple's latest iPhone has a better camera, pressure sensitive 3D Touch screen, faster processor and quick fingerprint sensor, but lives fast and dies before bed

The iPhone 6S is one of only a handful of smaller premium smartphones and promises fast performance, a great camera and new pressure-sensitive touchscreen.

In a world of smartphones with screens larger than 5in, the 4.7in iPhone 6S is in the minority. Most smaller smartphones are cut-down budget models with Sony's 4.6in Xperia Z5 Compact the exception.
