Today, consumers have a broad selection of premium phones
ranging from the Apple iPhone 6 to the Samsung Galaxy S6 to the LG G4. What’s common between most of
these phones is their focus on wireless performance, user experience, battery
life and photography. However, they do vary in these categories in ways that
set them apart from one another, in sometimes good ways and sometimes bad ways.
The differences
between these phones has also been illustrated by what SoCs (System On a Chip)
they use which vary from 2 to 6 to 8 CPU cores. Some SoC
manufacturers are even taking these high CPU core count designs and pushing
them towards 10 cores, a somewhat counter-intuitive and consumer-confusing
approach. I write about the “8 Core Myth” in regards to itsmarketing and an auto industry
lesson illustrating why the race to 8 and 10 CPU cores is a bad idea for
smartphones..
For my evaluation
of LG’s G4, I used the device beyond the standard two weeks and actually used
it for a month. I carried this phone with me always, and used it along with my
Apple iPhone 6 Plus and will be referencing other reviews to back up any of my
own experiences.
LG puts a heavy
focus on the camera
The thing you first
notice when you start using this phone is really how much effort LG has put
into making the LG G4’s camera as good as it is. As a result, they’ve
effectively made the camera the focal point of the phone and created an awesome
overall photo and video experience. They do this with a 16MP f/1.8 camera with
a 1/2.6 Sony sensor
and an 8MP f/2.0 front-facing camera. The main camera fires up in under half a
second after firing up the camera icon, but feels a much slower ~2 seconds when
you hold down the volume down button.
One of the reasons for the LG G4’s fantastic camera performance is because LG
has implemented their second generation of hardware OIS (optical image
stabilization). This feature allows you to zoom in on an image while recording
a video or taking a photo without the massive camera shake you normally expect.
This “hovering” functionality of the G4’s OIS is better than anything I’ve ever
using, including the Apple iPhone 6 Plus. The camera also has a
manual mode, which allows you to manually control the shutter speed, ISO,
exposure compensation, white balance, manual focus and even save the images as
RAW files. The higher-end camera features are great for experienced photographers,
but I’ll stick to the already very capable auto mode.
The LG G4’s camera is also capable of 4K video recording, which
is also made possible in part by the fact that the phone has removable storage
and can support up to 2TB of MicroSDXC removable storage. The LG G4 also has 4K slimport support making sharing 4K
content easier than ever before.
The end-to-end still
and video camera experience is orchestrated by the Qualcomm
Snapdragon 808′s balanced, heterogeneous combination of CPU, memory
controller, GPU, dual ISP, and DSP. The quality could never happen
without these components or the heterogeneous architecture of the camera
“system”.
LG’s design
decisions
The LG G4 has a
very simple plastic body that can be sophisticated and distinctive when
you add the optional stitched real leather back. The real leather is a welcome
change from the pleather of the Galaxy Note line of phones from Samsung. The
phone also has a curved back to more comfortably fit the natural curvature of
the hand, which is the exact opposite of the Samsung Galaxy S6 Edge whose
display is curved, but back is not, the exact opposite of the G4. Having a
curved back seems like more of a real design benefit rather than a gimmick. As
in previous generations of the ‘G’ family of phones, starting with the G2, LG
has put the physical buttons of the phone on the back. These buttons include
the power button as well as the volume up and down button. One of the ways that
LG works around not having front-facing buttons is with their tap-to-wake
display technology which allows you to wake up the phone with a simple double
tap of the screen. Even with all of this, I wish that they had a fingerprint
reader somewhere on the back.
Before LG launched the G4, they actually
announced the display that it would be using. The panel that LG
created for the LG G4 has some of the most accurate colors on earth with a 120
percent color gamut that works at a resolution of 2560 x 1440 at 5.5”
delivering a PPI of 538, nearly double that of the Apple iPhone 6 with a
PPI of 326. They also increased the brightness by 30% without increasing power
consumption and have a 50% higher contrast ratio than panels of the same
resolution.
As a result of the
design and this display, the LG G4 is a 5.5” phone that fits in your hand like
a 5.2” or smaller phone. It has a fantastic screen brightness of 500 nits,
which is virtually unheard of in a phone and significantly helps in outdoor
direct sunlight conditions. It also has a 1500:1 contrast ratio, whereas most
phones generally still have a 1000:1 ratio. As a result, of all this, the LG G4
simply has an awesome display, which is incredibly important nowadays as people
put more and more focus on the quality of their displays.
Connectivity
The LG G4 with the
Snapdragon 808 has some of the fastest connectivity on the market with Qualcomm’s X10 LTE modem,
capable up to 450 Mbps (Cat 9) with 3x CA. According to our
tests, Qualcomm is both faster and more energy efficient than
Samsung. Apple also uses a Qualcomm modem, so modem performance is similar
between LG and Apple. While most carriers in the world don’t support Cat 9 LTE,
there are already 13 networks in deployment, trial or testing. There are,
however, already 38 Cat 6 networks in deployment or trial and 64 commercially
launched CA networks.
The LG G4 also supports 802.11AC Wi-Fi as well as Bluetooth 4.1 LE which
results in some fantastic use cases. It also has features like NFC which one
would expect to be standard nowadays, but isn’t always, and will become more
important as Google rolls
out their second iteration of Google Wallet. Last but not least, the phone also
has Slimport 4K support, which means that showing the phone’s 4K content should
become a lot easier than transferring it to a storage device and playing it
from there.
Battery life and
charging
The LG G4, like its
predecessor is packed with an enormous battery. The LG G4’s 3000 mAh yielded me
a day of active use, which is impressive when you consider that the G4 has a
500 bit, QHD display and a Cat 9 modem. I suspect some reviewers that may have
found the battery life lackluster may not have been honest about how they
tested their display brightness.
From what I’ve seen, reviewers have pegged it at 6 hours of
screen time and 2 hours of full charge time on its 3000 mAh battery. The G4 had
16 hours of talk, 8 hours of web browsing and 7 ½ to 12 hours of video
playback. The Samsung Galaxy S6, by contrast had 7 hours of use and a 78 minute
full charge on its 2,550 mAh non-removable battery with 13:37 hours of video
playback.
Contrary to previous rumors, the LG G4 does support QuickCharge
2.0, but you need to have the right charger to enable it and the fact that LG
doesn’t supply one is a little disappointing. The phone also has a Super Power
Saver Mode, which works great for getting extra usage out of the phone. I kinda
wish more reviewers would test the longevity of this mode and see how much it
really improves battery life. It would also have been nice for this phone to
support wireless charging, like Qi or Rezence.
Storage
As mentioned
before, the LG G4 is one of the few phones out there still with removable
storage and battery. The reason for this is because LG understood that having a
camera capable of 16 MP photos, RAW photos, and 4K video would require a phone
to have more storage. This extra storage is easily accessible and upgradable
thanks to having a removable MicroSDXC card slot. The MicroSDXC card slot in
the G4 is capable of supporting up to 2TB of capacity, however those capacities
do not currently exist yet in the MicroSDXC form factor. As a result, the
biggest you can buy right now is 256 GB and that’ll set you back about $350,
but that also means you have double the storage of any phone in the world.
A more reasonable
purchase would be a 128 GB memory card because those can be had for between $78
and $99 and automatically put your phone’s storage in the highest tier of phone
storage sizes for a fraction of the cost. In fact, many 128 GB phones generally
will end up costing close to $1000 while the G4 with 128 GB of storage won’t
cost you more than $700. Beware of counterfeit cards and those mis-labeled as “micro”
but as long as you buy from a reputable retailer you should be fine. Also, for
a short period of time, T-Mobile is throwing in a
128 GB MicroSDXC card in for free, which is essentially a $100
value.
Software features I
liked and used
When it comes to
pre-installed software, more software doesn’t usually mean a better experience.
In fact, Samsung has removed much of the ‘bloatware’ they had pre-installed in
the past, while Apple has none and LG never had a lot of it. LG has done a
pretty good job of only loading the things that are necessary, which both
reduces clutter, performance hits and wasted storage capacity.
I also particularly
liked LG’s knock on feature which allows you to turn on the display with a
simple double tap of the screen. If you’re feeling adventurous you can also
unlock the phone’s screen with a knock code instead of a passphrase or pattern.
LG also included the QRemote, which is a very useful application of the IR
blaster on the phone which can allow you to remotely control your HDTV, AV
setup, projector, STB, AC and other appliances from your phone. It worked great
with my Samsung HDTV and Time Warner
Cable cable box.
Wrapping up
The LG G4 is an
overall fantastic phone that is made so fantastic by its incredible camera,
great display and leading connectivity. The phone stays awesome thanks to its
good battery life and fast charging, both of which are supporting a Snapdragon
808 SoC, which some people may forget is actually a 6 core SoC. The LG G4 is a
perfect example of how having more cores, be they 8 or 10 will not improve the
user experience in any meaningful way. I also suspect that we will see more
Qualcomm Snapdragon 808-based flagship phones before the year is over, simply
because of how well LG’s G4 utilizes an SoC that many criticized on paper as
being ‘weak’. The LG G4 is no slouch and you’d never guess how many cores it
has inside of it if you simply compared it against the Apple iPhone 6 and
Galaxy S6.
You can chock up
yet another phone with less CPU cores, like the Apple iPhone 6 that delivers a
really good experience.
