Hands-on: ASUS PadFone 2

Bigger, Stronger, Faster

It was about six months ago when ASUS launched the first generation PadFone in Singapore. Back then, the ASUS PadFone introduced a new handphone / tablet hybrid concept where the PadFone is able to dock into its Station to become a tablet, and morphs into a netbook with its Station Dock.

While the concept is truly innovative, our major gripe is the bulky PadFone Station which weighs a hefty 724g. Taking the feedback seriously, ASUS went back to the drawing board and improvise on the PadFone.

Today, ASUS took the wraps off the second generation PadFone, also known as the PadFone 2. Before we dive into the details, here's a quick rundown of the specs of the ASUS PadFone 2: -

Jerry Shen, CEO of ASUS was on stage to unveil the PadFone 2.


Compared to the first-gen PadFone, the ASUS PadFone 2 is "bigger" in almost every aspect. Right off the bat, you will notice a slight increase in the screen size from 4.3-inch to 4.7-inch. This essentially places the PadFone 2 among the big boys, the HTC One X and Samsung Galaxy S III.

While the first-gen PadFone utilizes a Super AMOLED display, the PadFone 2 comes with a Super IPS+ display which is based on Sharp's IGZO technology and is capable of delivering 550nits of brightness. 

This is rather impressive considering that the 10.1-inch display of ASUS Transfomer Pad Prime can deliver up to 600nits of brightness. We recently covered Sharp's showcase of the IGZO display technology at IFA 2012. To find out more about IGZO, click here.

Colors looked great and text appeared sharp on the PadFone 2 compared to the slightly high color saturation on the PadFone.

Due to the 4.7-inch display, the PadFone 2 is longer and wider but marginally thinner than its predecessor. 

The 0.2mm difference in thickness between the ASUS PadFone 2 (bottom) and PadFone (top) is negligible during our hands-on.

From top to bottom: ASUS PadFone (9.2mm), PadFone 2 (9mm), HTC One X (8.9mm) and Samsung Galaxy S III (8.6mm).

Similar to most high end Android smartphones, the ASUS PadFone comes with a microSIM card slot. The microSIM card slot is located at the top portion of the PadFone 2. Having said that, the PadFone 2 has a non-removable battery and does not come with a memory card slot.

microSIM card standard is fast becoming common among high-end Android smartphones such as the ASUS PadFone 2, HTC One X/XL/S and Samsung Galaxy S III/Note II.

The microSIM card slot replaces the Power button in the ASUS PadFone 2. The 3.5mm audio output jack remains in the middle.

The Power button is shifted to the right side of the ASUS PadFone 2 (bottom). Buttons retain the same tactile feel, which makes them easy to feel. Both PadFones sport tapered designs.


Hardware Specs 

One of the most prominent upgrades over the first-gen PadFone is the processor. It is the second Android smartphone after the LG Optimus G to be powered by Qualcomm's latest S4 quad-core processor. According to ASUS, the ARM-Cortex A15 chip delivers more power at higher efficiency compared to ARM-Cortex A9 chips. We wanted to conduct the Quadrant benchmark test on the PadFone 2, but we were told that the unit was a prototype.

Based on ASUS's slide, the Qualcomm quad-core processor in the PadFone 2 is more powerful than its counterparts in the Samsung Galaxy S III and HTC One X.

As points of reference, the first-gen ASUS PadFone with Qualcomm Snapdragon S4 dual-core processor scored an impressive 5,297 in the Quadrant benchmark while the Exynos 4212 Quad quad-core Cortex-A9 chip in the Samsung Galaxy S III managed a score of 5,294.

The NVIDIA-Tegra 3 processor of the HTC One X failed to match up with the competition with a low score of 4,025. Qualcomm also recently demonstrated the prowess of its APQ8064 chipset and its benchmarks results blew the competition out of the water.

With these numbers in mind, we are very excited to test out the review unit when it arrives. During our time with the PadFone 2, the user experience was very smooth. Considering that it is just a prototype and running on Android 4.0.4, we expect the finalized retail units to be even more impressive.

Another highlight of the ASUS PadFone 2 is its 13-megapixel rear camera. On paper, it is on-par with the LG Optimus G and Sony Xperia TX. Strangely, the aperture is smaller compared its predecessor at F2.4. A bigger aperture allows you to capture better images under low light conditions. We were unable to test out the camera's features and performance as the unit was a prototype.

ASUS claims that the camera on the PadFone 2 is superior to the ones on the HTC One X, Apple iPhone 5 and Samsung Galaxy S III.

Another highly touted feature of the camera on the ASUS PadFone is its ability to take 100 continuous shots at 6fps. Sounds like a good device for the paparazzi?

With a higher frame rate for video recording, the ASUS PadFone 2 should give you better and smoother videos.


No Jelly Bean Out of the Box

To be honest, we were disappointed that ASUS did not ship the PadFone 2 with the latest Android 4.1 Jelly Bean OS. With the Samsung Galaxy S III LTE and Galaxy Note II shipping with Jelly Bean out of the box, we did not understand why the PadFone 2 still runs on Android 4.0.4 Ice Cream Sandwich.

It is even more puzzling when you take into account that ASUS is the manufacturer of the Google Nexus 7, the first Android 4.1 device. When queried, ASUS stated that the Android 4.1 Jelly Bean should be out sometime next month, the same time frame as the expected launch of the PadFone 2 in Singapore.

An ASUS spokesperson stated that time is needed to integrate ASUS's exclusive technology, DynamicDisplay with Android 4.1. For those who are unfamiliar with the term, DynamicDisplay will ensure that the app remembers when you stopped so that you can immediately resume where you left off before docking the PadFone 2 and vice versa. 

Given ASUS's excellent track record in delivering Android OS updates to its tablet devices (1) (2), we are confident that the company will come up with the Android 4.1 Jelly Bean as soon as they can.


ASUS PadFone 2 Against the Competition 

ASUS unveiled the PadFone 2 at a time where competition is very stiff. LG stole the limelight recently with its Optimus G, the world's first quad-core LTE smartphone. HTC also recently released the One X+, an upgraded version of the One X. Samsung, as the top phone maker, is not resting on its laurels either with its introduction of the LTE version of the highly popular Galaxy S III. Here's a quick look at how the ASUS PadFone 2 fares against the competition: -
