Review: ASUS PadFone S Android smartphone cum tablet combo

As a pioneer of 2-in-1 mobile devices, ASUS offers with the PadFone S the portability of the smartphone and the larger screen of a tablet by selling both at the price of one device.

The PadFone S was launched in Singapore on 14 October, 2014 together with 11 other new mobile and computing products.

The PadFone S is a 5-inch Android smartphone that comes with a PadFone S Station.

The PadFone S I reviewed was the Pure White version. Normal retail price: S$449.

You can use the PadFone S on its own like any smartphone or you can slot it into the back of the PadFone S Station and use the combination as an 8.9-inch tablet, leveraging the larger backlit Super IPS display of the Station.

You can’t use the PadFone S Station on its own though, because it is simply a dumb display with no computer processors within.

Actually, the Station has more – it also includes a 4990mAh Li-Polymer (non-removable) battery to provide the larger energy demands of powering a larger display.

The larger battery can also be used to charge the PadFone S to extend its battery life from 22 hours talk-time (3G) to 64 hours.

The combined PadFone S in the Station felt a little bit hefty though, at a combined weight of 664g.

My view:
I found the ASUS PadFone S provided me with the portability of a smartphone and – only when I need it – a truely larger display and usability of a tablet –> all at the price of a single device (or less).

PadFone S – the smartphone on its own

The PadFone S is a 5-inch full HD LTE smartphone that runs on the latest Android 4.4 KitKat wtih ASUS ZenUI. It uses a Micro SIM card.

It is powered by a Qualcomm Snapdragon 801 quad-core CPU (2.3GHz) with 2GB mDDR3 RAM.

The phone ships with a non-removable 2300mAh Li-Polymer battery and has 16GB eMMC storage, with microSD card support up to 64GB (and free ASUS WebStorage of 5GB for life).

The 5-inch LED Backlight IPS display has 1920 x 1080 pixels at a resolution of 441 ppi (pixels per inch) and brightness of 400nits, supported by Adreno 330 graphics.

I found the display clear and sharp and usable even under bright sunlight.

Physically, the phone on its own feels light at 150g and measures 143.93 x 72.46 x 9.98mm.

Design-wise, the phone has a soft-touch back cover, and I like the brushed metal frame that goes around the phone.

There are two colours available – Dark Ruby and Pure White.

Audio-wise, the PadFone S comes with dual front speakers.

For imaging, there is a 2-megapixel f/2.0 front camera and 13-megapixel f/2.0 PixelMaster camera with LED flash.

I was impressed with the low-light performance of the PadFone S rear camera.

ASUS boasts that the PixelMaster technology increases the camera’s sensitivity by 400 percent and doubles the colour contrast, while reducing overall image noise.

I found that it could take pictures at lower light than other comparable smartphones.

PadFone S – when docked into its Station

The 8.9-inch LED backlit Super IPS display offers 1920 x 1200 (WUXGA at 16:10 ratio) pixels at 255ppi and a brightness of 390 nits.

The Station has a front 1-megapixel front camera and uses the rear camera of the PadFone S when docked.

The Station has its own Micro USB 2.0 host and stereo dual front-facing speakers with ASUS SonicMaster technology but uses the 3.5mm audio jack on the PadFone S.

In both the smartphone and docked configurations, you use the same data plan using LTE technology that supports up to 150Mb/sec downstream and 50Mb/sec upstream.

Docking/Undocking

I found the docking/undocking of the PadFone S into the Station easy and straightforward.

Simply slot the phone into the slot behind the Station and press lightly to click – the Station display comes to life and displays whatever was on the phone before docking.

This is where the PadFone S plugs into the Station. It’s designed to withstand repeated long term docking/undocking without succumbing to wear and tear.

Apps will instantaneously auto-adjust to take advantage of the larger display on the Station.

For undocking, simply pull out the phone from the slot and it’s ready to use as a normal smartphone.

The entire docking/undocking is seamless, so you can switch between the two configurations even in the middle of playing a game without having to pause or quit the app in between (provided the game is not a time-sensitive one).

ASUS ZenUI

The ZenUI overlays on the Android 4 KitKat the user interface that ASUS believes help users better use the phone.

Two personal organiser apps at the heart of ASUS ZenUI offer to help PadFone S users stay ahead of the power curve in their daily lives.

“What’s Next” manages your schedule, automatically displaying countdowns and reminders for your next appointment, displays canceled events, priority reminders for VIP contacts’ missed calls and birthdays, as well as getting to grips with your daily routine to make better use of your time.

Similar in functionality to Google Now, What’s Next reminds you about the next important task or event and identifies items that need a special reminder.

What’s Next is available through a standalone app, your notifications bar, a widget that you can place on your home and lock screens, giving you immediate access to everything that matters to you.

I found that it saved me from having to periodically check my schedule app, or memorise the next few tasks/events that are coming up.

“Do It Later” is a note-clipper app to help you capture things that crop up during the course of the day – so you can address them later – be it a text message, an article from social, a major developing news story, or a call that you just can’t pick up at the moment.

Simply add these tasks into Do It Later, where all of your tasks will be clearly listed in cards so you can quickly see what’s on your to do list.

You can click each item to go to the corresponding app and you no longer need to worry about being overwhelmed with information when you’re busy.

It enables you to focus and interfaces with What’s Next so that the little things don’t get forgotten in the daily bustle.
