What to look for a Smartphone?
1. Operating system
beyond Apple’s OS, there are four main ways to go: Windows Phone 7,
Google Android, BlackBerry and HP’s Web OS. BlackBerry is still best for
business, Android has great apps and the currently limited WP7 is ideal
for Smartphone newbies. All sync with your PC (and most with Mac) to
give mobile email, calendar and contacts.
2. Connectivity Bluetooth
is handy. Wi-Fi powers internet and email, HSDPA provides mobile
broadband everywhere and A-GPS means sat-nav. Look for compasses, too.
3. Screen Standard
resolution is up to 800×480 these days, but the real fun starts with
touch screen interfaces. The ideal scenario is a phone that offers
screen input and a dedicated QWERTY keyboards, although this adds bulk.
4. Apps as important the phones are the application they can run. The iTunes App Store is streets ahead; Android Market’s second.
5.
Battery Life
The life of a smartphone's battery is measured in two ways. The
first is standby time, referring to the amount of time the phone will
stay on when not in use. Most smartphones have a standby time of 140 to
400 hours, with an average of around 300 hours. Standby time is far less
important than talk time, which refers to the actual length of time you
can use your phone before the battery dies and the phone shuts off.
Most smartphones have a talk time of 3 to 13 hours, with an average of
around 5 hours. Four hours of talk time is sufficient to get you through
a workday as long as you do not use the added features for extended
periods of time. If you do use your phone features frequently, look for
five hours of talk time or more.
The best business cell phones have at least a 5 megapixel camera with
zoom features and the ability to play and record audio and video. These
cell phones act as life management devices and include organizational
features like calendars and task lists. Most sync with home computers
allowing for document viewing and editing.
The foundation of business is communication, and these product's first
function is as a cellular phone. These devices for business should
include all typical cell phone features including speakerphone,
three-way calling, voice dialing, call waiting, etc.
The most practical products are compact, include good input and display
options, and enough battery life to last through a full day’s work and
beyond.
Many cellular devices include practical tools like calculators, map
applications and GPS. Some have the ability to support third-party or
browser-based programs that can perform a variety of specific functions.
Third-party apps are becoming a key component, allowing the user to
customize their smartphones to support their lifestyles.
1. Apple iPhone 4S

The odds were stacked against the iPhone 4S claiming the top Smartphone
spot. But after putting it through a Tokeshi’s Costle-style assault
course with its fiercest rivals, there are only one conclusion- it
remains the world’s best all-round Smartphone. Its imaging skills are
class-leading thanks to a new 8 MP camera, which has a wide f/2.4
aperture and digital image stabilization. The 3.5in, 326ppi screen
remains the crispest in smart-world. And rivals still can’t match it
peerless sound quality, choice of apps or the charm of its
voice-controlled Siri personal assistant.
2. Samsung Galaxy II

The Galaxy II has it all; an incredibly vivid 4.3in screen, superb 8MP
camera (with 1080p video shooting) and Android 2.3 (Gingerbread).After
much testing we’ve come around to thinking that this is the Android
phone to buy, but the iPhone still has better apps.
3. Sony Ericsson Xperia Arc S

A return to form for Sony Ericsson, the Arc S slides up alongside the
Galaxy S II as the iPhone main rival. It has a dazzling 4.2in screen,
and the impressive 8MP camera takes 3D panoramas. Only the Samsung’s
superior might and build give it the edge.
4. Samsung Galaxy Nexus

The first Android 4.0″ Ice Cream Sandwich” phone also sports the best
phone display we have seen- a phenomenal 4.65in,1280×720 retina-pleaser.
Its 1.2GHz dual-core power makes it quick too, but its build quality
and camera don’t quite match the best.
5. Nokia Lumia 800

Nokia’s Windows Phone 7 flagship is a triumph, thanks to its charming
unibody build, vibrant 3.7in screen and increasingly capable “Mango”Os,
which now has Spotify. The dearth of apps at the moment, however,
remains WP7′s Achilles’heel.
6. Samsung Galaxy Note

The 5.3in Galaxy Note ousts the HTC Titan from our Top 10 to become our
favorite phone-tablet. Its 1280×800 screen is a joy for gaming, while
the 8 MP camera isn’t far behind the class-leading iPhone 4S. It’s not
for the small-handed though.
7. Blackberry Bold 9900

If you’re after a touch screen phone with a physical QWERTY keyboard,
buy this. The bold combines a premium stainless steel chassis with a
slick blackberry 7 OS. Its diddy 2.8in screen is, though a major
handicap for enjoying media or web browsing.
8. HTC Sensation XE

The Sensation XE brings a faster 15GHz processor and sound smarts from
Beats Audio. It’s a fine all-round Android phone, but the audio quality
doesn’t quite live up to its beats billing and a slightly under-par
battery life keeps it below the leading pack.
9. Sony Ericsson Xperia Mini Pro

Compact, affordable, touchscreen Android phones with slide-out QWERTY
keyboards are rarity, but the Xperia Mini Pro fills this niche
admirably. Its 1GHz processor runs Gingerbread Smoothly, and only a
sluggish camera shutter blots its copybook.
10. LG Optimus 3D

LG’s glasses-free 3D phone trumps HTC’s Evo 3D thanks to its bevy of
pre-loaded games and a capable 3D camera. A dual-core processor means
that performance is nippy too, and the long-awaited Android 2.3 update
has now arrived.
