The LG G4 and the Samsung Galaxy S6 are two of the most popular smartphones currently on the market. The LG G4 is known for its advanced camera and leather back, while the Samsung Galaxy S6 is known for its powerful processor and lightweight design. How do these phones compare to each other?

There are some things that the LG G4 offers and the Samsung Galaxy S6 does not, and some things that the Samsung Galaxy S6 offers and the LG G4 does not, according to GSM Arena.

The LG G4 has the bigger screen with a 5.5-inch display. The Samsung Galaxy S6 has a smaller 5.1-inch screen, but it has the superior display, according to Extreme Tech. The Galaxy S6 display is easily viewable in any brightness, especially outdoor daylight. The Galaxy S6's display is protected by Gorilla Glass 4 to prevent a shattered screen. The LG G4 uses its curved display to protect itself. This means when it is dropped, the center of the screen is unlikely to be damaged.

The Galaxy S6 wins the battery life test, despite the LG G4 having the bigger battery. Samsung is relying on its new, more efficient Exynos processor to use less battery, and it appears to have succeeded with that. A brighter screen is offered by the Galaxy S6, but Samsung still manages to make the battery last longer. The Galaxy S6 can last up to three days with casual usage. By comparison, the LG G4 only lasts up to two days with casual usage. The only advantage LG has over Samsung with its battery is the option to remove the battery, allowing for a fresh one to be installed.

The cameras offered on both smartphones are excellent, but this is where LG shines. The LG G4 offers a wide f/1.8 aperture lens on its 16 megapixel (MP) camera. The colors are excellent in the LG G4 and there is also a laser autofocus. The Samsung Galaxy S6 also has a 16MP camera, but with a f/1.9 aperture lens. Shooting moving objects is made easy with the Galaxy S6's tracking autofocus. LG boasts in ads how advanced its super-wide lens is, and this is a win for them.

The LG G4 uses a Qualcomm Snapdragon 810 processor. Samsung went away from Qualcomm processors and designed their own Exynos 7420 processor. In all benchmark tests, the Exynos 7420 used in the Galaxy S6 outperforms the Snapdragon 810 used in the LG G4.

Overall, the Galaxy S6 beats the LG G4 in almost every category. The advantages of the LG G4 are its removable battery and microSD slot, but the Galaxy S6 has the more powerful processor, sharper screen and longer battery life. Both smartphones come with a hefty price without a contract with the LG G4 costing $599 and the Galaxy S6 costing $649.
