Saw this earlier.
The battery comments are a common theme in all reviews. He's not actually a heavy user. He got better battery on the M9 too, but that doesn't have quick charge out of the box (you have to buy your own quick charger, that's lazy just like Motorola!).
The camera and screen as per usual got a lot of praise. These are the key selling points for this phone.
I tried out the S6 and edge properly in the shop today myself. I still feel the S6 looks very much like an S2-S5. It didn't look that different to me just because it had metal and glass. It was too 'Samsung-y' for my tastes and I wasn't feeling it. The screen was the best screen I've seen. I watched several trailers, photos and read text on the internet. It all looked pin-sharp and a heck of a lot more vibrant and sharper the iPhone 6 near it.
The build quality was great (nicer than the iPhone 6 but not quite as good as the M8/M9 yet in my opinion, those look and feel classier), the UI was fast but I got it to lag a few times by flicking through Flipboard, apps, gallery and a video. I'm putting this down to lollipop and the fact every single feature on the phone was switched on.
As good as it looked, I didn't like the front of the phone because I'm not a fan of the Samsung-y design of the Galaxy S and Note series. It's kinda like a 'design by committee' look and too conservative and safe. Not my thing.
So I went over to the edge and the screen on this is just amazing -- even better than the S6. I feel the curve gives the illusion that the image is closer to the glass and that makes quite a bit of difference to the experience. The glare wasn't that bad as a trade-off. The overall design was pretty darn good too and it didn't look like previous Samsung devices. The edges were a little sharp in the hand but it's something I can get used to. Really, the screen on this is something special; factor in all the other strong points of the S6, this is the model to get in my opinion. It's a shame the green model isn't available today otherwise I would have immediately bought one.
