Rated 5 out of 5 by nictrick from Amazing phone I use this phone in what I would say a moderate to heavy use. And even then, I only got close to running out of battery on the day that I watched you tube videos on it for a couple of hours. During normal days, the battery is still close to 50% when I go to sleep. If I were to activate the low power mode, or use it more conservatively, I could easily get 2 days use out of this phone. I love the size and the magnetic charging port. You can buy a cable for the magnetic port for just a few dollars online. I already got close to maxing out the internal memory, so I had to get a SD card for it. It was very easy to make work on ATT with full functionality.

Rated 5 out of 5 by PortableGamer55 from Games, Battery, High IP Ratings = GREAT Phone Playstation Gamer MUST! Android gamer get it, outdoors your thing, look at the IP ratings, this phone is for you. - Connects to a Dual Shock 4 for remote PS4 or controller supported Android games. SO AMAZING! - Only phone I have ever had that will last me two days on a charge. (I have a good amount of high end phones too.) - Really vibrant screen. - Big enough to enjoy small screen entertainment, not so big it won't fit in your front pocket. - Comes with Lolli update installed. - Camera is full of features and nails them all, even the 4K looks & runs amazing. - The last of the SD expansions in a high end phone.

Rated 4 out of 5 by Nuzzi from Beautiful Device... I tried the Z3 Compact first, then wanted the bigger one, so got this. This phone is great! Fast, smooth, nice display. It is as good as any Android device I have used. The waterproof piece puts it over the top. The one knock...it is slippery as heck. And finding a case at this time is very difficult. You can literally choose from thousands of cases for the iDevices or Samsung, but finding a case for this phone in the U.S. is not easy. I have seen maybe 3 options in person, all at the T-Mobile store. I do not like buying a case if I cannot feel it first. This is the only reason I gave it 4 stars instead of 5. The device itself is 5 stars all the way.

Rated 5 out of 5 by Anonymous from Build to be tough Z3 is not a high end phone for 2016 though it is build to be tough. It is water resistant, it has a good camera and when you enable hdr the photos looks very sharp. Recently I happened to use this phone in a desert area with 110 degrees and under direct sunlight. My friends iphone 6 was keep dying out as it was overheating this one though was keep going even though it was hot at the point that I couldn't put it into my pocket. I am also using the phone with google maps and GPS and it keeps going even though my dash board is getting very hot as the weather here in Southern California is really hot some times. So if you are looking for a tough phone this is the one you should be looking into.

Rated 5 out of 5 by SHL from Great phone with outstanding design and battery life I like the design of Z3 very much and believe it's the classic of all the Z series. Z3+ does't have good reputation in the heat issue and 820 processor but the design of Z3+ is more attractive. I don't consider Z5 simply because Z5 doesn't use shining glass for its back like Z3 and Z3+ do. The shining back glass is one of the features I like most. Another impressive feature is the battery life. The screen can be on up to 7.5 hrs in regular usage. Great phone like an art craft. You may see the pictures I took that will show the beauty of the phone and the shining back glass.

Rated 5 out of 5 by HL7 from Great value in a phone that is hardly out-dated I bought this phone for my wife based on my experience with the Z3 Compact, which I have been using for the past 19 months. While we have only had it a couple of weeks, the larger Z3 does everything the smaller compact does but just a little bigger, brighter and higher definition. Same high speed, same excellent phone and data reception, same support for noise-cancelling ear buds, and the same honest two days of battery life in normal usage. And it's really not much bigger than the compact, which surprised me. I can't say how this phone compares with the Z4 or 5, but it is far from obsolete, handling the latest Android update (Marshmallow) and any kind of app I've tried. At $300 it's a great value.

Rated 5 out of 5 by james n. from Sony makes a great phone First off just got MM update. Doze is noted for extending battery life. Guess what? It works great...but so did Android 5.1.1 with Sony magic. Getting 2.5 days before re-charge is needed before update. Now it's about the same. No complaints. Camera, memory. speed are all top-notch. Got this camera on sale because it's so old. I'm sure Samsung S7/e is a great phone....but 3 X as good? Please. Don't get caught up in the hype. Last years flagship is today's bargain. With B&H help of course. Just keep you eyes open and it will come. Good Luck.
