review sony Xperia Z3

hello i'm walid (the reviewer) and today i will you talk about the sony Xperia Z3 :

Sony's Xperia Z2, launched this April, was a mere nip and tuck away from smartphone perfection. But in the cut-and-thrust world of high-end smartphones, coming close just isn't good enough, and in the final reckoning we preferred the HTC One (M8) and LG G3. 

The good news for Sony is that just six months later it's having another go at it. And the good news for the smartphone-buying public is that the Xperia Z3 solves many of the problems of its predecessor while also adding a few genuinely unique features.

So while it may at first glance look like a mere incremental upgrade over the Z2, make no mistake: the Z3 is the real deal.

Battery life was the one thing we really wanted to test on the Xperia Z3. Why? Because to justify the lack of a 2K screen Sony has been throwing around bold claims that both the Z3 and Z3 Compact last two days of regular use. Now, looking in more detail at Sony's tests, it puts this two days as five hours per day of intensive messaging, gaming, web etc. 

Skeptical? So were we. There's a smaller 3100mAh battery (versus the Z2's 3200mAh unit) for starters. A brighter screen too. And Sony reckons the Z3 will last two days in the same conditions as those in which the Z2 lasts 1.4 and the Z1 lasts 1.2 days.

Well, it's time to set aside your cynicism - because the Z3 has the best battery life of any smartphone we've seen in a long time.

We haven't got it to two days on one charge yet but that's probably because we've been hammering it night and day. And since we received our test units, we've averaged a day and a half out of it without any of its (many) Stamina and battery saving modes turned on, largely thanks to the fact its standby juice-saving is brilliant.
 

It was even more impressive in our battery rundown, clocking just under 14 hours (13 hours 52 minutes to be exact) on our 720p video loop with Wi-Fi on and half brightness. Now, it's worth noting that the Xperia Z2 managed 12 and a half hours in the same rundown so it's not a huge difference on playback alone, but in regular use it's certainly enough to get you four or five extra hours on top of an already excellent battery life. The LG G3, in comparison, lasted for 9 hours 25 on the same test.

Sony puts the extra efficiency down to two things - the Snapdragon 801 processor, here clocked at 2.5GHz but also present in the Xperia Z2 - and a new display technology that it's developed which retains the memory of whatever is on the screen, meaning less reloading and more efficiency. It doesn't have a catchy name like Sony's other screen technologies, but it seems to be doing the trick. The only true two-day flagship we've tested is last year's brilliant LG G2 and the Xperia Z3 comes very close to matching it. 

Nosing around the settings, Stamina mode returns and Sony follows Samsung and HTC's lead with an Ultra Stamina mode. There's no Wi-Fi or data connection when you're in this mode, but otherwise it looks spot-on for festivals with phone, messaging, camera, contacts, alarm, clock, calculator, FM radio, settings and Bluetooth. Everything is still in colour, unlike rivals, and though there's no music playback and it takes 30 seconds or so to make the switch, it estimated seven days on 34%, so we can't argue with that.

No, really. All that Sony needed to do was make the best better, and it has done so here thanks to a few choice tweaks. For starters there's a new 25mm G lens for wide angle shots - with an Xperia Z2 on hand, you can immediately see how much more the Z3 fits in frame, which is good news for all those group shots.   SteadyShot for video has also been improved. The idea is to put an end to shaky footage so you can compete with all those Hyperlapses on iOS for smooth video when moving about and it works well against wobble-tastic video on lesser Androids.    Its main focus, though, is on making the Xperia Z3 the low-light photography king. The sensor now has light sensitivity up to IS0 12800; by comparison most phones will go up to only ISO 800 or so before giving up. It's worth noting that the extra sensitivity isn't available in auto mode and the difference over the Z2 isn't jaw-dropping, but all the same low-light photos are among the closest to compact cam quality we've seen. This Xperia's been eating its carrots.
