Asus ZenFone 3 Ultra ZU680KL Review: Overprice but Killer Display

We have already seen Zenfone 3 line up, where they have diversified their brand from budget segment to premium segment. We have already reviewed other Zenfone 3 line up like Zenfone 3, Zenfone 3 Max, and even the latest one Zenfone 3s Max. Finally today we are having Zenfone 3 Ultra, the device with 6.8″ Display. So, due to screen size you might have imagined that this device is more towards battery and display centric.

Initially when i start using the phone, it was really hard for me to get my full hands on that big screen size but after few days i get used to it and starting loving it as my daily driver. I can write on it using bluetooth keyboard, watching movies in Jio Cinema is awesome. This is not enough playing Batman Game is insane.

You can buy it from Flipkart for Rs. 49,900.

So, let start with the review of Zenfone 3 ultra.

Asus Zenfone 3 Ultra – Box Content

The Device comes in well built navy blue color box. Opening it from the top first we get the phone and nothing else. To get other accessories we need to slide down the box and there we all the accessories.

Accessories which comes within the box are:

  • Fast Charger
  • High Quality Type C cable
  • User Manuals
  • High Quality Premium In-Ear Earphones

Design & Built

Asus Zenfone 3 Ultra is available in three colours Glacier Silver, Titanium Gray & Rose Gold. When first i picked up the device in the hand it feels quite good and well built. I have never complained about the built in Zenfone 3 series, the only issue was the price. This time also in Zenfone 3 ultra we get great built with chrome at all sides, which elegantly increase the looks of the phone. Asus Zenfone 3 Ultra comes with the basic design form of Bar shape. The only issue i found was the device cannot be handled single handedly. But as it is under phablet category i would say best built till now.


Starting with the front part of the phone at the top we get a 8 Megapixel Shooter and beside that you get different sensors and a LED notification Light.


Coming little bit down you get a 6.8″ FHD display and i would say is one of the best display i have ever used (may be it is due to larger display).


Below that houses a back capacitive keys which do not light up (BUT WHY SO?). There you also get a Home button in which you also get a fingerprint sensor.


Coming to the down portion of the phone you will get a USB Type C port, which do support fast charging beside it you will get primary MIC and dual Speaker grills and the surprising thing is that both the speakers works and give quite loud stereo sound, rather i love the sound output from the phone.


Turning around to the top side you will get the 3.5mm audio jack and beside it houses a secondary noise cancellation MIC and nothing much over there.


On the right side of the phone, you get separate SIM trays. The top SIM tray can be used by inserting a nano SIM while the second SIM tray can take either a nano SIM or a microSD card slot that too upto 256GB.


Turning to the left side there is nothing, just a plane side.


Now finally coming to the back panel of the phone you will get a 23 megapixel camera which the support of laser autofocus and dual tone LED flash. Below that you will get Volume rockers because with this big screen it the best place to handle these volume rockers with ease. Below that there is just branding and nothing much to see.



Asus Zenfone 3 Ultra comes up with a 6.8 inch FHD with a resolution of 1920 x 1080 and pixel density of 324 ppi. The colors are quite vibrant and towards the more natural side. White balance feels perfect and makes it a pleasant display to use. There are different color profiles that you can choose as per your comfortability which we see in other Asus devices as well.

The Sunlight legibility of Zenfone 3 ultra is quite good, and auto-brightness makes it work perfectly, so no complaints regarding the display rather i would say this is the best display i have ever worked on just because of its larger display part. Watching movies is insanely awesome and take my word if you want to play games like batman you will nailed it because of HD display. Viewing Angle are good and odd angle won’t affect you in any way. Overall i love it.


Asus Zenfone 3 Ultra is powered by the Snapdragon 652 processor which 3/4GB Ram it depends which variants you are buying. The price in which the phone is being offered i would say processor is quite old rest when we practically see the performance no issue is with it. EVen after Snapdragon 625 the performance of the phone is quite well, and you can almost run any kind of High-end games or multi-task on it with no lag and sluggishness.


While playing some high-end games like Batman, GTA San Andreas, Bully I won’t find any lag or sometimes in Asphalt 8 i get some minors drops rest every game is working fine. While playing games for more than 30 minutes it get little bit warm but won’t heats up. The max temperature which I noted was 38 degree, which is quite cool for the gamers out there.
Honor 6X has almost all sensor which a consumer can demand like Gyroscope and many other, which means you can use VR on Asus Zenfone 3 ultra, but using VR with this big device won’t be a practical point.



On Asus Zenfone 3 ultra we get 23 megapixel camera which is supported with a laser autofocus and dual tone LED flash. The device capture decent images but need more work on software part. When using default app the images captured with the phone get some noise into it but using a third party app removed all the noise from the images and images came out to be much better. Overall this is not a more towards camera centric phone but it captures decent image quality rest you can check our camera samples for better idea.

On front side it will give you 8 Megapixel camera which also captures decent images, but when we compare it with other selfie centric phone that too in very low budget it is not upto the mark. Still we can say this is not a camera centric phone it is more towards screen, audio and built centric phone.

Camera Samples



Asus Zenfone 3 Ultra is loaded with Android Marshmallow 6.0 with a skin of ZenUI 3.0. The device has already received the update for Android 7.0 a few days back. The software of Zenfone 3 ultra is quite well optimized, in terms of battery but too much bloatware is loaded int it. The good thing is that we can remove the bloatware from the phone very easily.  lag free interface. The UI of Honor devices is inspired from iPhone and works perfectly well. Asus has also packed with a ‘Mobile Manager” in their ZenUI which gives you more info. on how much data you have used, power saving modes, notifications and privacy. It also comes with a One Hand Mode for some of the people who find it really very difficult to use the 6.8-inch screen phone. Still it is not meant for one-handed use in any scenario.

One thing i forget to mention over here is that, you will get 100GB storage free google drive storage with the device for one year as a promotion by Asus while botting the device for the first time.


As the device is so large with its screen size it is necessary to add up a larger battery. So, over here we are getting 4600 mAh battery which will just blow away your mind with the added features of battery modes. The battery gives some intense backup. In the battery modes we get different modes like Performance mode, Normal mode, Power saving mode and Super saving mode we can also customize the modes as per our usage and benefits.

While testing the device the, the phone get charge from 0% to 100% in 1 hours 45 minutes, that too is very great because charging that intense battery if 4600mAh will obviously take time with that fast charging feature also. Rest no complaints against battery part of asus zenfone 3 ultra.


So, the final verdict as per my views will be the device is good for its built, display and only focuses more on display part. If you want a large screen device to enjoy gaming, reading, movies with decent performance than this device is for you. Asus ZenFone 3 Ultra is priced at Rs 49,999. Everything is fine only the part which is not at all good is the pricing. WHY SUCH PRICING?.

The battery life performance is good, there are no noticeable flaws in performance. In fact, you the display size love will increase day by day when you will start playing games and watching movies on zenfone 3 Ultra.


  • Massive screen with great quality
  • Good battery backup
  • Good sound quality both with speakers and even with headphones
  • Great Battery Backup
  • Love the built quality


  • Pricing too High
  • Very difficult to use single handedly
  • Camera is only decent
