Introducing ZenFone
ASUS ZenFone is an all-new family of smartphones designed to
personify the essence of simplicity and reliability.
ASUS is famous for its market-leading tablets and notebooks, which
blend high-quality materials with new innovations that focus on
adapting to the user. ZenFone (and, by extension ZenUI) is no
different in this regard, but we are bringing these high-value
innovations to the mainstream sector.
ZenFone is designed to fit around you and its innovative features will
allow it to become a key ingredient in your life. It helps you to sort
through life’s chaos by organizing your schedule and helping you to
remember the things and people that are important to you.
ASUS engineers have worked hard to ensure ZenFone seamlessly
integrates into your life and begins to understand what you need. It
fits perfectly into your hand with the buttons just where you expect
them to be – right under your fingertips.
ZenFone manages to balance premium features and components
with affordability – it was borne from our world-renowned ‘design
thinking’ philosophy, adapting to users’ needs with features that are
designed to make their lives easier.
At the heart of every ZenFone is a super-fast quad-threaded Intel®
Atom™ 2500 series processor running at up to 2.0GHz. Intel
processors offer the best performance and power efficiency in their
class, enabling you to focus on getting things done rather than
worrying your smartphone is up to the task. Apps open quickly,
games run smoothly and you can effortlessly browse the web. What’s
more, ASUS ZenUI is buttery-smooth and HD video is stutter-free,
ensuring the ZenFone mobile experience is an uncompromised one.

ZenFone 5 – Your Everyday Companion
Colorful and stylish design
With edges that taper to 5.5mm at their thinnest point and a
comfortable 145g weight, ZenFone 5 is designed to fit perfectly into
your hand. It lets you focus on what matters most to you.
Its design was inspired by the classic ASUS ZenBook, ZenFone 5
includes the iconic concentric circle finish at the bottom of the front
fascia to give it a timeless look and feel. Through precise CNC milling
with 45-degree diamond cuts at an exacting 0.13mm pitch, ZenFone’s
concentric circle finish has an incredibly fine texture that feels as
good as it looks.
You can customize your ZenFone 5 to suit your mood or personality
with one of four different removable Zen Cases – available in
Charcoal Black, Ceramic White, Cherry Red and Twilight Purple.
ASUS designers worked to perfect the different back covers so that
they offer a premium feel. They are put through more stringent testing
than the industry standard to ensure they are able to withstand
everyday knocks and scrapes. What’s more, ASUS ZenUI software is
customized to match your chosen back cover color for a complete

A beautiful 5-inch display
ZenFone 5’s 5-inch high definition 1280 x 720-pixel (294ppi) IPS+
display is bright, crisp and spacious. It features wide 178-degree
viewing angles that enable you to effortlessly share content with
friends. To minimize dents and scratches, it’s protected by Corning®
Gorilla® Glass 3 and uses direct bonding to enhance color clarity.
We’ve worked to ensure that the device doesn’t get in the way of
what matters most – the 5-inch display is a beautiful window to your
world that enables you to express your thoughts and feelings by
connecting you with those closest to you.
ZenFone 5 not only has a class-leading 60ms touch response, but
ASUS engineers have also worked to develop an ultra-sensitive
touchscreen for those times when it’s too cold to remove your gloves.
ASUS GloveTouch is an exclusive technology that allows you to
operate your ZenFone 5 while wearing gloves – whether you need to
check the route to your next meeting with Maps, reply to an email
while you’re waiting for the bus, or just check what your friends are up
to on Facebook, you can do so without frustrations. Best of all, you
don’t need to buy special touchscreen gloves as GloveTouch
technology is designed to work with your favorite pair of winter

ASUS PixelMaster Camera
Taking photos and recording videos has never been easier. ZenFone
5 incorporates an 8.0 megapixel ASUS PixelMaster camera with a
bright f/2.0 five-element lens on the rear. There’s more to ZenFone’s
camera than just its headline specifications though – PixelMaster
enables a whole host of innovative features that are designed to
make shooting photos and videos simpler, more rewarding and more
PixelMaster is a unique ASUS-developed technology that combines
software, hardware and optical design to deliver incredible image
quality and produce professional quality photos. ASUS camera
engineers are particularly proud of ZenFone 5’s optical formula, which
features five brightness-enhancing lenses for excellent optical
performance and distortion-free photos.
With PixelMaster, we focused on creating the best shooting
experience so that everything is instinctive and, because your
ZenFone is with you all the time, you can capture every moment.
Central to this is the ASUS Camera software, which presents often
complex controls in an unintimidating but accessible manner – it is
the front end for the hard work that our engineers have put in behind
the scenes to make this one of the best smartphone cameras
available. For those who just want to take pictures or record video,
the interface is minimal and it smartly monitors whether a particular
mode would be more suitable for any given scenario, but ASUS
Camera’s advanced controls are there for those who wish to use
them, and they are also easy to find.
Low-Light Mode
Low-light mode delivers unparalleled performance in poor lighting
conditions, without needing to use the flash — no matter how dark it
is, PixelMaster’s low-light mode allows you to take clear photos or
videos of objects and their surroundings. We achieved this through a
combination of adjusting the pixel size and optimizations made to the
image processing algorithms, which allows us to increase the
ASUS ZenFone 5 Reviewer’s Guide
April 2014
sensitivity by 400%, boost color contrast by 200% and also
significantly reduce overall image noise.
Time Rewind
By switching Time Rewind on, PixelMaster automatically helps you to
record images two seconds before and one second after pressing the
shutter. During this three-second period, 31 photos are recorded so
you can select the best photo – you’ll never miss that perfect
expression ever again.
Image Stabilizer
By automatically analyzing and comparing the reference points in
images drawn on the sensor, PixelMaster’s built-in image stabilization
technology is able to ensure that photos and videos are clear and
ASUS ZenFone 5 Reviewer’s Guide

shake-free, no matter whether you’re walking down the street or on a
Turbo Burst
Blur from moving objects can’t be corrected with this technology, and
in these situations speed is everything. Turbo Burst mode will help
you to record those high-speed moments with incredible clarity by
shooting high speed bursts at 13 pictures a second. Once you’ve
finished recording the moment, you can select the best pictures and
discard the rest.
Selfie Mode
Taking a selfie has become increasingly popular and fun social
experiment over the last several years, so ASUS engineers worked
hard to improve the quality of those photos by enabling ZenFone
users to use the high resolution rear camera to take selfies. You
simply enable selfie mode, select the number of faces and the
camera will automatically launch a countdown timer as soon as it has
detected the correct number of faces. It will then take a burst of three
photos to ensure you get the best results.
ASUS ZenFone 5 Reviewer’s Guide
April 2014
You can still shoot selfies with the 2.0 megapixel f/2.8 front-facing
camera too – which is particularly useful if you’re trying to juxtapose
yourself against a background using ZenFone’s screen. This camera
also functions as a 720p video camera for video calling.
Full HD Video Recording
Capture special moments in 1080p Full HD using the PixelMaster
camera on ZenFone 5. The large 5-inch display and minimalist
camera interface gives you a great view of what you’re recording.
Low-Light mode is available to improve the clarity of videos shot in
poor lighting conditions, while video stabilization ensures your videos
are shake-free. You can also shoot full resolution photos while you’re
filming, allowing you to remember those beautiful moments even
more vividly.
Powerful and Efficient Intel® Atom™ Processor
ZenFone 5 is powered by a quad-threaded Intel® Atom™ Z2580
processor which runs at 2GHz to deliver class-leading performance
and power efficiency. Apps open quickly, the all-new ASUS ZenUI is
buttery smooth, HD movies are stutter-free and you can effortlessly
browse web pages without hiccup. Everything feels fast because the
processor doesn’t get in the way.
The Atom processor’s PowerVR SGX544 MP2 graphics processor
also packs a serious punch. It supports OpenGL ES 2.0 (as well as
several OpenGL ES 3.0 features through a series of API extensions),
DirectX9_3, OpenGL 2.1 and OpenCL 1.1 standards, enabling
stunning visual effects that were once only possible on desktop
computers and games consoles.

All-day battery life
With an energy efficient Intel Atom processor and optimized antenna
design, ZenFone is able to combine class leading performance with
all day battery life. With talk time of up to 18.5 hours and almost 14
days of standby time, ZenFone 5’s 2110mAh (8Wh) battery enables
you to do more of the things that matter to you.
ZenFone 5’s advanced antenna design provides fantastic
performance in areas with poor signal (for example, in the metro or a
tunnel) and has also been tuned to reduce power use when searching
for a signal. This results in a two-fold increase in standby time on its
ZenUI is a new holistic user experience developed specifically to get
the most out of ASUS smart devices. It’s simple and intuitive, but has
greatly enhanced functionality – it’s a perfect example of the ASUS
‘design thinking’ philosophy at work.
The new ASUS ZenUI has been meticulously designed to help users
make the most of the fantastic functionality packed into every ASUS
ZenFone. It knows what the user needs, helps them to express their
thoughts and feelings, and keeps them connected wherever they go.
The built-in apps adopt a beautiful frameless design that aims to
make it easy to identify what it is you’re doing. The app icons are

simple and intuitive, tying in with the apps themselves so that it’s easy
to find what you need from memory.
ASUS engineers have made more than 200 different modifications to
the base Android operating system, but have always kept one thing at
the center of any enhancement: performance. Added functionality is
only useful if performance is uncompromised, so we focused on
making ASUS ZenUI as fast and smooth as possible.

What’s Next
At the heart of ASUS ZenUI is What’s Next, which helps you to
manage your schedule. It automatically displays 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
With intelligent technology that gains an understanding of your needs,
we can ensure that the phone doesn’t become a burden in your life by
unnecessarily interrupting you when you’re busy, enabling you to
focus on the big picture while your ZenFone worries about the details.
We understand that you are busy doing what you love, so What’s
Next helps you to work through your daily schedule without
interruption. What’s Next will immediately remind you about the next
important task or event, identify items that need a special reminder,
and reduce the number of distractions so you can focus.
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.
Do It Later
Mum sends you a text message, you see an interesting article shared
by friends on social media, there’s a major developing news story, or
a colleague calls and you can’t take it because you’re busy. Do It
Later can help you remember those things that are important to you
to save you from those embarrassing or awkward moments.
Simply add these tasks into Do It Later, where all of your tasks will be
clearly listed in beautiful 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
