4.7" iPhone 6.

Does the TouchID recognition seem faster now? (And works better with sweaty hands.)

Apps that are blown up seem a little big, but very useable. The blown up keyboard in that mode is easier to type on.

The speakerphone is louder.

Battery life seems very good - the same or better than the 5s. I took a 2 hour 40 minute hike today, running Nike + Running the whole time, listening to either podcasts with Overcast or off-line music on Beats with a couple of connections to check email and it only took 13% of the battery. It'd usually take 20% on the 5s.

It's definitely bigger and I notice it most when taking in/out of my pocket.

Still early days with it.
