Asus Zenfone 3 Ultra Review

When Asus launched the Zenfone 3, they launched the Zenfone 3 Ultra along with it. The phone was launched for people who are looking for a smartphone cum tablet like device. Asus tried to redefine the word phablet here but is it worth buying?. Let’s take a look at device and every aspect that it has to offer in this review of the Asus Zenfone 3 Ultra. Let’s get started by listing the specifications that it carries.

Asus Zenfone 3 Ultra Key Specifications

Design & Build Quality

The first thing that you will notice when you look at the phone is how huge the phone and the screen is. The front has a 6.8-inch display and below that, you will find the home button which is also the fingerprint reader here. There are two touch sensitive buttons for back and recent apps as well. Above the display, there’s an earpiece along with the 8MP front camera and sensors.


Flipping the device on the back reveals the primary camera on the back along with the dual tone LED flash and the laser autofocus unit. There’s also a volume rocker on the back and below that is the Asus branding with the Zenfone branding on lower side of the device.


There are two trays for SIM & SD card and both of these trays are on the right edge of the phone. The first tray can hold only 1 nano SIM card while the other can be used for inserting a microSD card or another SIM card. The power button also resides on the same right edge along with the trays.


The bottom of the phone has a USB Type-C port along with the speaker grill and the mic. The top of the phone houses the secondary noise cancellation mic along with the 3.5mm audio jack.

The device has a really good build quality and the metal used here is good and it doesn’t flex. However, the device is big and might not fit into your pockets fully.


The screen used here is a 6.8-inch IPS LCD touch display with a resolution of 1920*1080 pixels. This converts to a pixel density of about 324 ppi which is good for a display of this size. It would have been better if Asus went for a 1440p display but 1080p works well too.


The display looks good and can produce good colors. Watching movies and multimedia content on this screen is a pleasure due to the size of the screen.

Camera & Imaging


Asus claims that the 23MP camera on this phone is able to take some really good photos. The primary unit is fully loaded with laser autofocus and PDAF for focusing on objects faster. You also get an aperture of f/2.0 which means better low light performance and above everything you get 4-axis Optical Image Stabilization which works very well in shaky conditions.


The front facing camera of 8MP is a good choice too. The camera has a wide angle lens and can take great selfies too. Both of these cameras work well and they are coupled with Asus’s great camera app which will provide you a lot of options & customizations to take the perfect shot.

Hardware, Software & Performance

The phone has a Snapdragon 652 which is an octa-core chip. You can choose to have the 3GB or the 4GB RAM model. If you are planning to use the phone for multimedia consumption then the 3GB RAM version will work fine but if you want to game on this thing, you should go for the 4GB RAM version.

The phone can handle games but at this price, we expected better processor. you can easily get snapdragon 652 powered smartphones under 20,000 INR.

The phone runs on Android 6 Marshmallow with ZenUI 3.0 on top. Now, there are a few modifications to the system but you can compare it with stock Android, you won’t find much difference here. Asus has added extra apps like the Mobile Manager etc. and apart from that, it’s just visual alterations. The phone performs well and can handle apps and mid range games easily with this configuration.

Battery Life, Price & Verdict

The phone has a battery of 4600mAh and it supports Quick Charge 3.0 which can charge 60% of the battery in 45 min. This is a good thing about the phone and Asus is utilizing all that space very well. The only thing that’s a turn off about the phone is its price.

The phone is priced at Rs. 49,999 which in my opinion is a bad pricing. You will find much better phones in the price range. But then, people are still buying this phone because it does have something to offer i.e a huge display and Asus has used top quality components to build the phone.
