[Review]Sony Xperia Z5 Premium - the first phone at 4K


How do you turn down a phone that's claiming 4K resolution?  People balked at QuadHD display, saying you can't see the difference, but I could.  And now almost all devices are QuadHD.

So the switch to 4K will even be bigger coming from QHD than going from FHD to QHD.  I had to find out.

Thankfully the Sony Z5 Premium eventually did come to Canada through Bell, and to pick it up for just $750, or $200 on contract.  Not a bad price for the first ever 4K phone.

But how does it really stack up?  Well, Sony was kind enough to send the device on over for me to play with, so let's have a gander.



First up, let's look at those specs:

  • 5.5" @ 3840x2160
  • Snapdragon 810 (1.5GHz x4 + 2.0GHz x4)
  • 3GB RAM
  • 32GB storage + microSD
  • 23MP (1/2.3") G-Lens / 5MP
  • 3430mAh
  • Android 6.0 (after upgrade)
  • IP68

Okay, let's take the bull by the horns here and first talk about the resolution.  I mean, really, that's why you'd pick the Z5 Premium up over the Z5.

I reviewed the Z5 previously and ... well, I wasn't super impressed, but it got the job done.  I'm not going to rehash a lot of what I covered on the Z5, because it's essentially the same phone, just bigger, 4K and more battery.  So, check out that review for a review:  http://www.androidcoliseum.com/2015/11/sony-xperia-z5-review.html

Right, now back to the resolution.

4K.  The jump from 1080p to 1440p was about 33% gain.  Going from 1440p to 2160p is a 50% gain.

4K does look cool - I shot a small video comparing 3 phones at 3 different resolutions.  You can watch it here: http://www.androidcoliseum.com/2016/04/comparing-phone-resolutions-fhd-quadhd.html

4K looks amazing on the phone.  There is a noticeable difference.  The only problem is that it's really only going to turn on to 4K when it's watching something at that resolution, when it doesn't sense the higher resolution of 4K it reverts back to 1080p for everything else.

Even when I filmed my comparison shot, trying to get a YouTube clip at 4K it couldn't do it, only when I had a native 4K file.  

Shame.  I was really hoping.

That piece aside, it's essentially the Z5, but bigger.  So, the main difference you'll be opting for this phone over it's smaller sister phone is the size.  Do you want 5.2", or 5.5"

The advantage of going to the 5.5" display size is that you also increase the battery by almost 20%, that definitely accounts for something.  It definitely lasts longer (so long as you don't use 4K for all that battery time.

But, bigger also comes at a cost of design.  Not a big issue, but the blocky nature of their design means it really feels like a hefty slap.  Now, I compared it to my G3, which I thought was my thinnest phone, but it's actually not as thick, it just feels it.  LG, Samsung, etc.. all have thin edges against the glass and then round or taper out to the middle, where as Sony is just a slab all the way around.

It's not thicker, it just feels like it.  And you actually may like it.  I'm starting to prefer having something 'solid' in the hands - my work made me get an iPhone 6S and the thing feels ... flimsy skinny.  I feel much safer with the slab (especially as I don't like cases).

One thing to consider here is that the device still has a very slippery back glass.  Even if I put it on the arm of the couch you can see it ever so slowly glide it's way precariously to the lowest point.

It's a good phone, very snappy, just like the Z5.  But like the Z5 I didn't like the button placements, and for the size it makes it still just as awkward.  Having that fingerprint scanner there on the side means it's hard to get to if it's laying on a table.  Luckily, it has double tap to wake, and then swipe up to get to the code screen.  I do really like how as soon as you enter the code you go straight in, unlike with Samsung you have to enter the code, THEN hit OK.

So, overall, for $100 difference from the Z5 you'll get 0.3" more screen, 20% more battery and the odd time you'll watch a real 4K video, it'll be able to display it.

Is it worth it?  You tell me.  For the battery, I might do it.  And I do like a larger screen, but the larger screen also increases the bezels, making it a pretty large phone overall.  Still very manageable for me tho'.  For you?  You'll have to pick one up and give it a try.


Here's some screenshots showing of the typical Xperia options (seen also on the Z5 review)

mini apps are pretty cool

ooh, OEM unlocking

make it look different from others!

actually glove mode works really good

customize the Quick settings shortcuts

Lifelog is fun and a neat version of Google Fit, S Health or LG Health

I don't like this move to these non-alphabetic lists

Ooh, 3 free movies!
