Samsung Galaxy S6 edge vs LG G3

Design

The Samsung Galaxy S6 edge disrupts the traditional Galaxy smartphone look with its curved screen and premium build.The LG G3 has just a simple plastic build that's of admirable quality, but certainly doesn't look and feel as impressive.The Galaxy S6 edge have Gorilla Glass 4 layers covering its front and back. Save for its semi-faux metallic sheen, the LG G3 doesn't have anything to show in the way of luxury, but its strong card is ergonomics.

the Samsung Galaxy S6 edge measures 5.59 x 2.76 x 0.28 inches (142.1 x 70.1 x 7 mm) at a weight of 4.66 oz (132 g), while the LG G3 is a bulkier 5.76 x 2.94 x 0.35 inches (146.3 x 74.6 x 8.9 mm) and a heftier 5.26 oz (149 g). The Galaxy S6 edge is more compact because its display has a lesser diagonal - 5.1 inches versus the LG G3's 5.5 inches, and it is lighter, although made of stronger materials.

Display

The Galaxy GS6 edge has a 5.1-inch Super AMOLED 1440x2560 screen with an extremely high pixel density of 577, making individual pixels nearly impossible to discern. The LG G3 has a 5.5-inch IPS LCD display with the same resolution, but a lesser pixel density of 538ppi due to the increased diagonal.

he Galaxy S6 edge's display is rather close to the most neutral color temperature of 6500 K, which is an achievement. It's also not over or under-saturated, which is particularly pleasing... that is, as long as you have it set to the Basic screen profile.. Meanwhile, the LG G3's color temperature of 7099 Kelvins is not too far off the reference value either, but this color temperature.

In terms of brightness, the GS6 edge's display can hit well above 500nits (about 553, to be more specific), which is an excellent achievement for an AMOLED display. It means you can reliably use this screen outdoors or in bright light. On the other side of the scale, the GS6 edge accomplishes an excellent minimum brightness value of 1 nit, which makes for easy bedtime reading. How does the LG G3 fare here? Well, it has a tolerable maximum brightness level of about 455 nits, which means you can use it under direct sunlight or bright lighting conditions with a little effort. And, its acceptable minimum brightness level of 9 nits means you can use it in dark rooms without retina-searing experiences, although admittedly, the screen should have been a bit darker. 

Interface and Functionality

The latest TouchWiz on the GS6 edge looks better and it's easier to get around, although phantom gestures launching random features and apps is still a 'fun' conversation topic. As for LG? Well, its software design used to be rather lackluster, but the company learned from its mistakes too, and did a good job with the LG G3's user interface. It streamlined it by exchanging imitations of real world objects for basic shapes colored in light, non-distracting shades. 

TouchWiz and LG UX both succeed in bringing simple, meaningful functionality to the lucky user. But although we like LG UX for being so straightforward, we find it somewhat bland and underdeveloped compared to TouchWiz, which has grown into a cohesive, aesthetically pleasing, and feature-rich platform.

Processor and Memory

The Galaxy S6 edge with a homemade SoC, the Exynos 7420. It's a 64-bit octa-core CPU built on a 14-nm process, and so far, we've been impressed by its performance. It employs four Cortex-A57 cores running at 2.0GHz, and four Cortex-A53 cores pushed to 1.5GHz, arranged in a true octa-core configuration (all eight cores can be utilized simultaneously). This performance beast is paired with a very capable Mali-T760 graphics unit and 3 gigabytes of fast LPDDR4 RAM. 

The LG G3 hasSnapdragon 801 SoC, but that's only because it's a year-old unit at this point. In reality, Qualcomm's quad-core 32-bit chip with its in-house designed Krait cores and Adreno 330 GPU has aged well, offering decent performance even with today's demanding games and high resolution video content. On the memory side, the LG G3 is equipped with either 2GB (for the international model) or 3GB of LPDDR3 RAM (for the Korean model), and it is a solid performer overall, although the Quad-HD resolution puts the hardware under significant strain – its performance and battery life fall short of the expected from a high-end smartphone.

Internet and Connectivity

Samsung Galaxy S6 edge and the LG G3 are Wi-Fi, Bluetooth, NFC, GPS, 3G, and LTE-connected, which means they cover all the necessary networking bases. Also, both have microUSB 2.0 connectors for data and charging. The Galaxy S6 edge supports Bluetooth 4.1 - it's 4.0 for the LG G3 - but both have Wi-Fi 802.11 a, b, g, n, n 5GHz, ac wireless internet. In addition, both offer DLNA and Miracast for smartTV streaming, along with tethering for doubling as a USB Modem/Wi-Fi hotspot.

Camera

Galaxy S6 edge won't be one to diminish it with sub-par performance. Its main camera resolution is 16 megapixels, and the sizeable Sony IMX240 cam sensor with 1/2.6" pixels and wide F1.9 aperture comes with goodies such as optical image stabilization, real-time HDR, infrared white balance, and tracking auto-focus for the video camera. There's also a 5-megapixel front cam to please the selfie snappers. 

LG G3 sounds less impressive with its 13MP main camera that comes with 1/3.06"-sized pixels and a smaller aperture (F2.4), while the front snapper is only a 2.1MP cam. But in practice, both are no-nonsense performers that don't disappoint, even if the end result is not in the same league as the GS6 edge's. Notably, the LG G3's camera is very quick and accurate with its focus duties, thanks to its laser-assisted auto-focus system. It also takes flat-out nice photos in good lighting conditions. However, we must acknowledge that the LG flagship often goes for an image that's a little too warm and vibrant.

As for video quality, both the Galaxy S6 edge and LG G3 offer up to 4K resolution video recording with frame rates of up to 30FPS and optical image stabilization, making for clear and stable sights from the main camera. Image quality is very good in both, but the Galaxy S6 edge operates much faster thanks to its UFS 2.0 flash memory - the process, from opening the app to saving the video and viewing it on that high-res display, is a breeze! Moreover, the GS6 edge can record 1080p video at 60FPS from the main cam if you are into that sort of thing

Multimedia

Galaxy S6 edge's hardware superiority doesn't give it much of an edge over the LG G3, as both smartphones support the latest HEVC 2.5 multimedia encoding and decoding standards. This means rich format support out of the box, and with both devices touting big, crisp displays, it goes without saying you'll be enjoying every minute of high-resolution video. As for loudspeaker performance, the G3 manages a decent 81db out of its mono speaker, which trumps the GS6 edge's 75.4dB output. With the LG G3, you can totally listen to some music in your car, for example, but the sound quality is tinny and hollow – you know, typical tiny speaker affair. The GS6 edge also sounds a bit subdued and thin, which is normal.

Call quality

The LG G3 fares better in this regard. Loudness is pretty decent on the incoming side, and voices tend to sound clear. On the other end of the line, things sound just as good – your contacts will hear your voice rather clear and natural. 

Moving over to the speakerphone, the one on the GS 6 edge is powerful enough to use in noisy environments without having us to ask our callers to repeat themselves. The same goes for the LG G3.

Battery

The Samsung Galaxy S6 edge carries only a 2600mAh battery. This may not sound very assuring on paper, but with a 14nm-made SoC in play, Sammy's hero phone manages to squeeze 8 hours and 11 minutes of on-screen usage, covering the bare minimum (a full workday of on-screen use) that we consider appropriate for a recent high-end smartphone. The LG G3 houses a sizeable 3000 mAh juice pack, but don't take that as a guarantee for endurance. LG's last year flagship delivers a mediocre battery performance, lasting 6h and 14 min of constant on-screen use in our specialized battery life test. Although it lasts two hours less, the LG G3 can pull through at least 8 hours of moderate use, so things aren't all bad here.
