Performance and battery life
There’s one thing that needs to be clear: Optimus
G is a performance monster. Subjectively, it hasn’t missed any beat – everything
is fast and smooth, without delay or latency. Regardless of releasing with Ice
Cream Sandwich (Android 4.0.4), it feels faster than our Galaxy Nexus and stay
on par with Galaxy Note II, both run Jelly Bean. This is a proof for UI
optimization of LG, the design ability of Qualcomm or both. In our tests, Optimus
G sits between the present champions in most tests – the international version
of Galaxy S III (ICS) and Galaxy Note II (Jelly Bean) while defeating both with
the best Quadrant score we’ve ever recorded for a phone (7,628) and only beaten
in AnTuTu test (11,284). The results are the same in the 3 versions, with Sprint
model lagging behind the other 2 models a little bit. It will be interesting to
see how these numbers improve once Optimus G is updated to Android 4.1.

SunSpider: the lower the score, the
better
We don’t have any problem with the overall
radio performance but the calls are a little small in the tests. The phone of AT&T
is the clearest one, following by Sprint, with Korean Optimus G (may not be
optimized for the American network) staying at the bottom. The preinstalled
speaker sounds a little low but still loud enough. We don’t have time to
compare the music playback with other phones, but the sound quality with many
headphones and earbuds is worth with higher-than-average standards of us. It’s
worth mentioning that the preinstalled music and video player of LG has Dolby
Mobile, if you want to enhance audio. The speed tests on LTE network of AT&T
in San Francisco offers about 12Mbps/download and 10Mbps/upload (average) with
4 out of 5 signal bar. Until Sprint deploys LTE at Bay Area, we will perform
the speed tests on CDMA, which means the highest speed of 2.3Mbps/download and
1Mbps/upload with full signal. The Korean phone only supports GPRS data in
America, but we have seen some impressive numbers with the original Optimus G on
U+ LTE network of korea while we’re in Seoul.

Battery life on dual-core Snapdragon S4 devices
of Qualcomm is normally amazing, and we’re satisfied to announce that this
trend continues with Optimus G equipped with quad-core Snapdragon S4 Pro. While
the 3 versions all have the same sealed 2,100mAh Li-polymer battery, we focus
our attention to the model of AT&T because it’s the only one with active LTE
connection. Our standard battery test includes setting brightness and volume at
half level, using 4G in 75% or better signal area, activating GPS and WiFi (no
connection) and disabling Bluetooth while repeating a video from a full charge
until the battery is drained. Optimus G of AT&T runs for about 8 hours 43 minutes;
model of Sprint lasts 7 hours 53 minutes on 3G (LTE is off); and our Korean
phone continues to run in 8 hours 40 minutes on 2G (disabling LTE and HSPA+).
In moderate battery-using test, consisting of using a phone lightly from a full
charge until the battery is drained – emailing, sending messages, checking the
social networks, making short calls, taking some photos… – all the 3 models
last for almost 20 hours. So, we’re pretty sure that most of the users won’t
have any problem using Optimus G all day long. With users who use a lot, they
can use “Eco Mode”, a settings that lasts the battery life by switching
aggressively between quad-core and dual-core operation.
