The ASUS ZenFone 3 Ultra (ZU680KL) Phablet Review

Setting Up The ZenFone 3 Ultra

The ASUS ZenFone 3 Ultra runs on Android 6.0.1 Marshmallow, which should be familiar to many Android users. It is very easy to setup. If you are setting it up as a new device, it should take you only 5 minutes to finish the setup process.

It’s Alive!

When you power it up for the first time, you will revel in how sharp the 6.8″ IPS display looks. This is partly because the screen is laminated with the Gorilla Glass 4 cover. This not only makes the display thinner, it also increases contrast and reduces internal reflections.

Holding the ZenFone 3 Ultra in one hand is possible, but the weight means you will end up hooking your little finger around the bottom to prevent it from slipping. There is a One Hand Operation mode you can enable, but the ZenFone 3 Ultra is best used with two hands.


Available Memory & Storage

The ASUS ZenFone 3 Ultra comes with either 3 GB or 4 GB of LPDDR3 memory. Our review sample came with 4 GB of memory. Only 3.5 GB is usable, of which 1.5 GB is used by the Android operating system and background apps. This leaves only 2.1 GB of free memory to use.

The ASUS ZenFone 3 Ultra also comes with generous storage capacities of 32 GB, 64 GB and 128 GB of flash memory. Our review sample came with 64 GB of flash memory. Out of the box, just under 52 GB is available for use. That should be plenty enough for most users, but is expandable via a microSD card (up to 2 TB).

    It’s a pity that the Zen Phone 3 Uttra has The same screen resolution of the other smaller phones. Just seems a waste of potentially a great big display.

      They could have gone with a 1440p display, but that would mean greater cost and power consumption for arguably no real benefit. With a pixel density of 324 ppi, it would certainly qualify as a “Retina display” at the standard viewing distance.

      Remember – this is a large phablet, so we are more likely to view it at a distance. You can’t tell the difference with say, the Galaxy S7 edge, unless you compare them side by side and peek close-up.

        As all three devices have the same resolution the DPI would change depending on the display size. The Ultra would not give you anymore screen realestate just a larger display. The idea of a phablet would be to increase screen realestate to make it a more productive device compared with a smaller ( non Phablet ) phone.

        I would love to see manufacturers take the phablet size of six inches or larger and turn them into higher end devices rather than the middle spec devices we are seeing now.

          Correct, the ZenFone 3 Ultra won’t give you more pixels, just a larger screen.

          If you are viewing movies on a range of phablets at a distance of, say… 10 inches, a larger screen is arguably more enjoyable, but the higher resolution on any of these phablets won’t be noticeable.

          If you are looking to work on a phablet, then yes, the higher resolution will matter… a LOT. Sadly, the only phablet that is close to 6″ with 1440p resolution is the Galaxy Note7.

          Peter you are right!

          Im looking to replace my aging xperia z3 tablet compact which is 8inch to a slightly smaller 6+ inch phablet. But it seems non of the newer phablet are high end devices.

          Even Sony’s XA Ultra is powered by the mediocre Mediatek chipset instead of something higher end.

          The Ultra was something I was considering but the price for that mid range chipset seems a bit too much also…

          1. Peter

            Hi Terence,

            I have a real problem with manufacturers building large screen devices with questionable specifications. If these devices where cars then they would have an SUV chassis with a compact cabin being powered by a small 1.6 litre engine. What’s the point?

            Why not manufacture a large screened phablet with high end specifications and call it a flagship device. Just giving a phone a large screen without the benefit of higher resolution just makes it suitable for media consumption rather than a device suitable for media creation and productivity.

    Hi..just to ask from your experice reviewing this phone..did you noticed that the website,whatsapp and facebook app display are quite small despite the big screen size.The good thing is we can see more things in a screen.I tried changing to fonts to largest size but it is still the same
    i did comparison with xiaomi mi max..the display of a website in mi max is larger and fit the screen
    I suspected this is related DPI optimization
    Can you give some comments?

    1. Dr. Adrian Wong Post author

      That may be due to the higher resolution 1080p display. The icons and text will seem smaller, if you are migrating from a lower resolution 720p display, for example. Then again, the Xiaomi Mi Max has the same resolution.

      Unfortunately, we no longer have the ZenFone 3 Ultra with us, so we cannot confirm it on our end… 🙁
