Despite using Tegra 3 processor with
energy-saving feature plus large battery capacity (2,140mAh), this LG quad-core
smartphone doesn’t impress us upon its runtime.
Optimus
4X HD’s battery was overrated
Optimus 4X HD is a LG quad-core Android
phone supposed to be launch into Vietnamese market this July at an unspecified
price. The model is equipped with a Tegra 3 quad-core processor (1.5GHz), 4.7-inch
LCD screen plus HD 720p resolution equivalent to One X of HTC. Two models both
runs on Android 4.0 but Optimus 4X HD exceed with a battery capacity of
2,140mAh while that of HTC One X is only 1.800mAh.
However, our practice has shown that this
model’s runtime wasn’t much impressive and just a little more than that of One
X and even lower than those of Galaxy S III, Samsung’s quad-core phone with
bigger screen plus 2,100mAh battery.
3G
talk time test
In our first test, Optimus 4X HD was
continuously used to make phone call via 3G and it could handle in 7 hours and
41 minutes. The result wasn’t bad at all but when compared with the rival
having the same specs, HTC One X with a 10-hour talk time, this result was
inconsiderable.
Test
on web browsing via Wi-Fi
The most disappointing quickly appeared in
our second test on web browsing. LG’s 4inch quad-core smartphone took less than
4 hours to consume 90% battery capacity. Consequently, this phone lay in most
energy-consuming ones and of course, lost to its direct rival HTC One X for 20
minutes.
The
final test’s result was disappointing, too
Our final test didn’t help LG Optimus 4X to
gain any point when it continued to rank around the bottom. The 2,140mAh
battery’s capacity decreased from 100% down to 10% when constantly playing
videos in 4 hours and 14 minutes. Meanwhile, One X and Galaxy SII could last
1.5 hours and 6 hours longer, respectively. Additionally, the 5.3inch Galaxy
Note’s runtime is twice as much as this smartphone’s one.
LG
Optimus HD 4X battery’s performance is not convincing
If we chronically use each hour per day for
3G video calling, Wi-Fi web browsing and video playing, the model can handle in
40 hours. However, due to poor results in tests of video playback and
web-browsing, this LG quad-core smartphone isn’t well appreciated in battery
lifetime as it was introduced.
