I've got a Z3 and I'm amazed by the battery life. I used to have an Xperia Z1 and I've noticed a very obvious leap in battery life.

I don't know what average phone usage is like for most, but I would say I use my phone a lot. It gets a lot of music, youtube, Internet and whatsapp time in a day. The screen is on a lot (flippin bright screen too) and not once has my battery come close to dead.

I'll put it this way, I used to have to be careful with my battery. Now, I never even check it. It's very good.

Aside from the battery, the phone itself is really great in practically all respects, I'm really happy with it.

One thing I wasn't expecting with it, which is something I think I love the most with this phone, is the look. I have the copper Z3, and every time I look at it, I think, damn that is one sexy phone. I wasn't expecting it but the copper z3 in real life has got to be the best looking phone I have ever seen. I've had a lot of other people comment on it too, and because it's a less common phone model as well, it really catches the eye. Compared to a boring iPhone.

The z3 is a quality phone

I have Z1 and I can typically go two days without recharging. If Z3 has an even better battery life, I want that thing to be transplanted into my chest when my heart stops beating. Just because.
