Optimus 4X HD Battery Life Appears Unconvincing

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 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.

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.

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.

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.

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.
