1. INTRODUCTION-
• Smart Phones are defined
to be enhanced mobile
phones that perform
functionalities other than
the typical phone.
• These enhanced features
can be anything from email
and internet to a full
keyboard.
• The definition of “smart “
keeps changing as more and
more new functions are
introduced to mobile
phones.

3. Comparison of two Smart Phone
iPhone 5s
Vs
Samsung Galaxy S4

4. The new normal
Just like when we compared the Galaxy S4 to 2012's
iPhone 5, we're looking at a big difference in overall
size. Samsung's phone is ten percent taller and 19
percent wider than the 5s. Both phones are pretty
thin, but the GS4 is also four percent thicker.
During the last couple of years, Android phones
have completely rewritten the definition of a
"normal" sized smartphone. The iPhone used to be
considered the standard; now it looks very small
next to its competitors, including the GS4.
The iPhone 5s is 14 percent lighter than the GS4, but
both feel extremely light in hand. When you look at
relative weight (weight-to-surface-area ratio), the
GS4 actually measures in at 11 percent lighter.

5. Big screen, small screen
Screen size is still one of the biggest differences
between these two phones . If you're comfortable with
the Galaxy S4's feel in hand, then you'll get to reap the
benefits of a much bigger display.
The Galaxy S4's screen also takes up a higher portion
of its front face, and provides a much bigger window
peering into your apps, games, and videos. We don't
think screen quality is an issue on either phone. There
are, however, a few key differences. The GS4's is much
sharper (441 pixels per inch to the iPhone's 326 PPI),
though we're really comparing The GS4's AMOLED
display also saturates colors more, Many customers
still enjoy the iPhone's smaller screen. Galaxy S4's feel
in hand and pocket, then there's really no benefit to
going with a smaller screen.

6. VIP access
The iPhone 5s' killer feature is invisible to the naked eye.
It's the most consumer-friendly biometric fingerprint
sensor that's ever been made.
When setting up your iPhone 5s, you'll be given the
option to activate Touch ID. Teach the phone your
fingerprint , then set up a passcode. You'll be able to
unlock your phone by holding that finger over the home
button for a moment, while anyone else will need a
passcode.
The Galaxy S4 doesn't have a fingerprint sensor, but it will
soon have a similar blend of security and convenience.
Once it's compatible with theGalaxy Gear
smartwatch (via a software update that is supposedly
coming this month), you can set the phone to require a
pattern lock if out of range of your watch.

7. Camera comparison
The iPhone's shot looks more saturated, and has higher
contrast. Both shots look very much like typical smartphone
flash photography, but the iPhone's "True Tone" Dual-LED
flash appears to make its look a little less washed out.
If you're going to split hairs over photo quality, then we'd
probably cast our vote for the iPhone. Especially when you
throw in its terrific burst mode (which automatically chooses
the sharpest shot) and slow-motion video features, we'd say
its camera has the edge. But the GS4's camera is no slouch
at all, and you could easily argue that its quality was at least
as good in all of the above samples, apart from the last low-
lit shots.

8. Battery life comparison
On a technical level, the iPhone 5s has a 1,570 mAh
battery, while the Galaxy S4 holds 2,600 mAh of juice.
Based on our experience, both phones' batteries should
last a full day for almost any kind of "typical" use.
In our more formal test, where we stream video with
brightness set at 75 percent, the iPhone 5s came out far
ahead. It lasted about six hours and fifteen minutes. The
GS4, meanwhile, only lasted around four hours and ten
minutes.

9. Performance and processors
Both of these phones fit that bill. The iPhone's A7 chip
makes it the faster phone, and this is reflected in
benchmarks. But at this point, that's almost like telling a
soccer mom that this racecar is faster than that racecar.
Both are extremely zippy and responsive, and likely far
beyond what you'll ever need.
The most notable item about Apple's A7 system-on-a-chip
is its shift to a 64-bit architecture. This is significant for the
future of not just iOS, but mobile devices in general.
Though the iPhone 5s only has 1 GB of RAM, future 64-bit
iOS devices could support over 4 GB, making mobile
devices a bit more like their desktop counterparts. This
could have a ripple effect throughout the entire mobile
landscape, because as Apple goes, others tend to follow

10. Software features
iOS 7 is Apple's first big cosmetic makeover of its
mobile operating system. In addition to its new flat
design (fewer shadows, reflections, and simulated real-
world objects), you get a few new features thrown in.
Our favorite new feature is Command Center, Apple's
better-late-than-never quick settings menu. Slide up
from the bottom of the screen, and do things like
toggle Wi-Fi or Bluetooth, adjust brightness, or change
your music track.
iTunes Radio also makes its debut in iOS 7 .iOS 7 also
gives you improved multitasking, which now shows you
live preview cards of your open apps. AirDrop also
makes the leap from Mac OS X, letting you easily share
media files with nearby friends (provided .

11. We could write a book on the software features that
Samsung threw into the Galaxy S4, but we'll just stick to a
few of the most memorable. We're looking at a laundry
list of features, most of which we never used after our
first five minutes with the phone. Most infamous are
gimmicky air gesture and eye tracking features, which we
never found very useful. Smart Stay, however, which
keeps your display on as long as you're looking at it, is
actually pretty handy.
The Galaxy S4's similarly-exhaustive selection of camera
features is a bit more practical. This includes not just the
standard HDR and panorama modes, but a sports mode
(simulates a much better camera's high shutter speed), a
portrait mode (enhances and focuses on faces), and Best
Face, which lets you, in a group shot, choose each
person's best-looking face, before merging them into one
final product

12. Conclusion
It's hard to go wrong with either phone, but they each
have their pros and cons. The iPhone 5s is light and fits
easily into just about any hand, but its screen is small and
the phone is only slightly changed from last year's iPhone
5. The Galaxy S4, meanwhile, has a big and gorgeous
display, but its construction looks cheap next to the
iPhone, and many of its software features are gimmicky
wastes of space.
How do you choose? Well, we can't do that for you. But
we think this will give you a nudge in the right direction,
and help you to find the phone that works best for you.
