LG G4 UX 4-0

LG G4 UX 4-0

The LG G4 has a surprising chipset, Qualcomm’s hexacore Snapdragon 808 (it comes with two Cortex A-57 cores running at 1.82GHz, and four Cortex A-53 cores running at 1.44GHz), coupled with the Adreno 417 graphic system. After Snapdragon 810, this is the second most powerful Qualcomm CPU, which might disappoint those expecting the best for a flagship. Still, when it comes to synthetic benchmarks, LG G4 is just slightly behind the most powerful devices on the market, while even leading in some tests.

In practice, you won’t be able to tell the difference anyway. What is more, the LG G Flex2, which features Snapdragon 810, showed issues with the chip overheating. This would cause it to slow down after prolonged and continuous use. The LG G4 doesn’t have these problems, which is why we’re not disappointed by the 808.

The Adreno 418 is a different story. It’s not a significant upgrade from the G3’s Adreno 330, and it struggles with graphically-intensive games on the G4’s QHD display.

Battery Life and Software

The G4 has a 3000mAh battery, just like the G3. Unfortunately, that doesn’t mean that battery life is the same.  Specifically, the G4 uses more power when making calls and while in stand-by mode, and uses less juice to power the display and while browsing the internet. So if you chat a lot, expect to charge a lot.

The G4 ships with Android 5.1 (Lollipop) and LG’s Optimus UX 4-0 UI. Visually, LG’s UX aligns with Android’s Material Design, and the tweaks are light. The UX includes all familiar LG particularities, including the double screen tap to wake and sleep the device and smooth system task animations. An additional display called SmartBulletin is a novelty. It is located left from the main Home Screen and introduces a personal notifications stream, not general notifications like HTC’s BlinkFeed, but those solely connected with the device’s owner.

The LG G4 has the best camera on a smartphone yet. Its essence includes a 16-megapixel 1/2.6-inch sensor (compared to the smaller 1/3-inch sensor on LG G3’s 13-megapixel camera) and comes with 3-axis optical image stabilization (instead of the G3’s 2-axis stabilization). What likely contributes most to image quality, especially in low-light situations, is the camera’s speedy F1.8 lens. Finally, LG G4’s sensor captures 80 percent more light with all of these features than the G3’s, and the G3 was a great cameraphone in its own right.

The G4 is unrivaled when it comes to image sharpness and level of detail. Exposure is also praiseworthy, and shadow-filled shots look fantastic, complete with details in the dark with no overexposure on the light subjects.

The G4 camera also includes a so-called laser autofocus, which locks in shots with exceptional speed, and ColorSpectrum technology, which detects ambient lighting and adjusts white balance accordingly, making the colors more realistic and vivacious.

The fast lens coupled with the optical image stabilization really lends itself to excellent night photography, and the G4 definitively tops the competition in this category. We took some excellent shots even in the default Simple mode, and the camera has a decent set of control options in Manual mode.

The same praise applies to video recording as well. The G4 records 2160p with 30 fps or 1080p with 60 fps.

The selfie camera is not as spectacular, but has been significantly improved from the G3. It has 8 megapixels, up from two, and a wider shooting angle.
