Hands-on: ASUS PadFone Mini and ZenFone Series

Hands-on: ASUS PadFone Mini and ZenFone Series

ASUS Goes Intel for New Smartphones

ASUS is becoming one of the strongest supporters for Intel Atom processors as an increasing number of its mobile devices are powered by its processors. First announced in February 2013, the Intel Atom "Clover Trail+" processors have been appearing in recent ASUS devices such as the Fonepad, Fonepad Note FHD 6 and the Fonepad 7

One month ago at Consumer Electronics Show (CES) 2014, ASUS unveiled four new smartphones powered by Intel Atom processors. They are the 4-inch PadFone Mini, the ZenFone 4, ZenFone 5 and ZenFone 6. We dropped by the ASUS booth at Mobile World Congress (MWC) 2014 today to check out these devices. Here's our take.


ASUS PadFone Mini

The PadFone family is known for its unique concept of docking a smartphone with a tablet station, and the PadFone Mini fulfils the needs of consumers who want a 7-inch tablet. 

The PadFone Mini is a 4-inch smartphone which can dock into and power a 7-inch tablet station.

Design-wise, the Fonepad Mini has a striking resemblance to the BlackBerry Z30 as it has a lighter grey accent at the bottom lip of the device. Above the accent are the three standard navigation buttons (back, home, recent), a design trait that you either hate or like it. Some consumers do not want software buttons as they take up unnecessary screen estate while there are others who think capacitive buttons are outdated.

Even though the chassis of the PadFone Mini is made up of plastic, we were surprised by its solid feel.

Unlike its more expensive and premium PadFone devices, the PadFone Mini is targeted at the entry and mid-range market segments. To cut costs, the chassis of the PadFone Mini is made up of plastic. We were actually very surprised by the build quality of the device when we first picked it up as the PadFone Mini gave a very solid feel. The matte texture also helps in giving it more grip and a professional look compared to glossy plastic.

It is easy to slide and remove the PadFone Mini from the station dock.

We had no problems sliding the PadFone Mini in and out of the station dock; it was a smooth experience. The phone also appeared to be secured tightly in the station dock, hence it shouldn't slide out that easily.

The station dock sports a 7-inch display with a resolution of 1,280 x 800 pixels.

As mentioned earlier, the PadFone Mini is not a flagship smartphone. Its specs include an Intel Atom Z2560 dual-core 1.6GHz processor, 1GB RAM, Android 4.3 Jelly Bean (upgradeable to Android 4.4 KitKat), 8GB internal storage, microSD support up to 64GB, a 4-inch WVGA (800 x 480 pixels) display, an 8-megapixel rear camera with f/2.2 aperture and a 1,200mAh battery. It measures 124.42 x 61.44 x 6.3 ~ 11.2mm and weighs 116g.

The combined weight of the PadFone Mini and station dock is about 376g, which is a little on the heavy side considering that the Huawei MediaPad X1 weighs only 239g. However, you have to take into account that there are two devices - the 4-inch PadFone Mini and the 7-inch Station dock - and the Station dock has a 2,100mAh battery.

The PadFone Station dock is 13.91mm thick and weighs 260g.


ASUS ZenFone Series - 4, 5 and 6-inch

The ZenFone is a new series of smartphones that ASUS announced at CES 2014 that offers three display sizes (4, 5 and 6-inch) for different needs of consumers. 

The ZenFone 4 looks very similar to the PadFone Mini.

We are clueless on why ASUS offered a ZenFone in the 4-inch category since it will be competing with the PadFone Mini for the same group of consumers. Perhaps there are some consumers who may not want or need a 7-inch tablet and just want an Android smartphone that can easily be used in one hand.

ASUS has done a good job with the design and build quality of the ZenFone 4.

Most of its specs are similar to the PadFone Mini except for a lower processor clock speed of 1.2GHz and a 5-megapixel rear camera. Its weight is lighter at 115g, making it quite easy to use in one hand and carry around.

This is the ZenFone 5 with similar design traits as the rest of the family.

The ZenFone 5 is a slightly more powerful smartphone; it comes in two variants: one running on the Z2580 dual-core 2.0GHz processor and the other powered by the Z2560 dual-core 1.6GHz processor. It also supports dual micro-SIM cards.

As the name suggests, it has a 5-inch display with a higher resolution of 1,280 x 720 pixels. The ZenFone 5 is equipped with an 8-megapixel rear camera with f/2.0 aperture, and a removable  2,100mAh battery. It measures 148.2 x 72.8 x 5.5 ~ 10.34mm and weighs 145g. In comparison, the Xiaomi Mi 3 weighs the same while the LG Nexus 5 and Samsung Galaxy S4 with LTE+ tip the scales at just 130g. 

The ZenFone 6 is ASUS's first phablet device.

The ZenFone 6 is ASUS's first foray in offering a phablet device aside from the Fonepads which we viewed them as tablets. As its first attempt, the ZenFone 6 has quite decent specs such as an Intel Atom Z2580 dual-core 2.0GHz processor, 2GB RAM, 6-inch 720p display, 13-megapixel rear camera with f/2.0 aperture and a 3,300mAh non-removable battery.

Due to the 6-inch display and 3,300mAh battery, the ZenFone 6 is quite heavy at 196g and measures 166.9 x 84.3 x 5.5 ~ 9.9mm. To put these figures into perspective, here's how the ZenFone 6 measures against the recent 6-inch phones:

  • HTC One Max - 164.5 x 82.5 x 10.29mm, 217g
  • LG G Flex - 160.5 x 81.6 x 8.7mm, 177g
  • LG G Pro 2 - 157.9 x 81.9 x 8.3mm, 172g
  • Nokia Lumia 1520 - 162.8 x 85.4 x 8.7mm, 209g

In general, all three ZenFone devices sport the same build quality, feel and finish. Similar to the PadFone Mini, we were surprised (in a good way) by how good the devices felt in our hands. 

The rears of the ZenFone devices reminded us of the HTC One X and One X+.



ASUS introduced a sublime new user interface (UI), the ZenUI on its latest four mobile devices. It has simplified icons and menus with five different color themes to match the color of the device. One of the more noticeable new features is What's Next, which reminds the user of missed calls, new messages and important dates.

You may have noticed What's Next in a number of photos earlier. This is how What's Next looks like on the new ASUS devices.

What's Next is deeply integrated into the Zen UI. By default, it is shown on the lock screen as a widget where you can resize and place anywhere. Notifications from the people you contact or care about the most are compiled together on a separate screen. It also has a smart function where it will notify your peeps via a phone call, message or email when you are running late for an appointment. Reminders on upcoming appointments are shown on the widget too.

The icons look very similar to that of some new device which was announced just two days ago.
