LG Optimus 4X HD Review
The dual noise-canceling mics on the LG Optimus 4X HD did a good job taking out the ambient fluff while we were talking, and the other party said they could hear us loud and clear enough. On our end the sound in the earpiece was just average - neither very strong, nor overly clean, with a bit of an echo, but we could tell the speaker’s voice and didn’t have trouble hearing them fine two notches below maximum volume.

A new SiO+ technology has been used for the battery, says LG, and the change occurred after the handset was announced. This allowed the capacious 2150mAh juicer to pack more lithium ions in less space, making for the compact body it’s in. The battery is quoted for the way above average 11 hours of talk time in 3G mode.

In our daily grind with the handset we did notice that the screen seems to consume much less energy than the 4.5” HD one on the Optimus LTE, for example, but power consumption in standby is pretty significant with Tegra 3, compared to the Snapdragons. Thus despite the large battery you won’t be able to squeeze more than a day and change with power use.


The LG Optimus 4X HD is undoubtedly the best Android smartphone that the company has produced to date. It covers the geeky ground with a quad-core Tegra 3 chip, large and vivid HD display and the latest Android 4.0 out of the box.

The design is simple and pleasant, with a few welcome twists that make the phone a looker from the prism-shaped sides and easier to grip. The handset is more compact than its main rivals this Android season, despite being crammed with the same high-end innards, making it easier to operate with one hand. The only complaints are its preset screen brightness management and the funky camera focus, so hopefully these will be addressed with the first software update.

The new LG Optimus 3.0 UI is an improvement over its predecessor with a number of new features like Quick Memo and a very functional lock screen. Video playback is vastly improved with the new Media Plex features like live video zoom, and the camera module has been given new abilities like the Time Machine precapture. Nothing groundbreaking, but coupled with the light and quick ICS, the UI overlay feels sufficiently enhanced.

Whether or not LG’s best Android effort to date succeeds will be the market’s decision, as it stand against some pretty hefty opposition. The HTC One X has very similar components, but more stylish unibody design, yet all is for the sake of expandability, as it has a sealed battery compartment and no memory card slot.

The Samsung Galaxy S III also sports powerful silicon, but is with a more distinctive design and a slightly larger Super AMOLED HD display, not to mention the better camera. Yet the LG Optimus 4X HD offers the most flexibility out of the three flagships in this price range with its regular SIM slot, removable battery and expandable memory, so if that’s your thing it’s an easy pick.
