LG G3 vs Samsung Galaxy S5: What's the difference?

LG has officially unveiled its much-rumoured LG G3 device, succeeding the LG G2 that it launched in September last year and bringing with it a number of exciting features.

The question is however, has LG done enough with its new flagship to take on its current competition and win over the hearts of those looking to upgrade. Here we are comparing the LG G3 to the Samsung Galaxy S5 to see which Android device comes out on top in terms of specs and where the differences lie between them.

The LG G3 has a bigger, sharper display

The LG G3 features a 5.5-inch display compared to the 5.1-inch screen offered by the Samsung Galaxy S5 so LG's offering gives you an extra 0.4-inches but it isn't just size that matters.

LG's newest flagship also ramps up the resolution to 2560 x 1440 pixels, giving it a pixel density of 538ppi, while the Galaxy S5 has a 1920 x 1080 resolution that provides a pixel density of 431ppi.

In terms of numbers the LG G3 is a clear winner when it comes to sharpness and clarity as there is a big step up in the amount of pixels per inch but it's worth remembering that we did think the display on the S5 was great when we reviewed it.

The Samsung Galaxy S5 is smaller and lighter

When it comes to the design of these two devices, it will ultimately boil down to personal preference so it is difficult to put one over the other here.

The LG G3 measures 146.3 x 74.6 x 8.9mm and weighs 149g compared to the Samsung Galaxy S5 that measures 142 x 72.5 x 8.1mm and hits the scales at 145g so the LG G3 is slightly larger, thicker and ever so slightly heavier than the Galaxy S5.

The Galaxy S5 takes a plastic, textured removable rear path, while the LG G3 takes a smooth, metal approach and both handsets have their own design features on the rear.

LG opts for a slightly redesigned signature volume rocker that was originally launched on the LG G2 and adds a camera sensor and twin-tone flash, while Samsung introduced a heart rate sensor to the rear of the Galaxy S5.

Both come in a string of colours with LG offering gold, gunmetal, white, red and purple compared to Samsung’s blue, gold, white and black options.

Samsung has also added water-resistance to its Galaxy S5, while LG has steered clear despite the rumours so the Galaxy S5's IP67 rating can be completely submerged in water down to one metre before it faces issues but the LG G3 needs to be kept above land.

Both devices have the same processor

If you aren't leaning towards either device based on its individual design then the speed of the processor under its hood isn't going to help sway you either as both feature the same chip.

The LG G3 and the Samsung Galaxy S5 both opt for the 2.5GHz quad-core Qualcomm Snapdragon 801 processor and 2GB of RAM so you should find the performance of a similar standard in both. An LG G3 variant with 3GB of RAM will be available too, but the company is yet to reveal in what region(s) that might be released.

We found the navigation of the user interface to be a little slower than we thought it should be when we reviewed the Galaxy S5 so we will certainly be testing the limits of the LG G3's performance when we get it in for full review.

You'll get the same maximum amount of storage on both devices, and both have 16GB and 32GB models, although we're not yet sure which will be available for the UK version of the LG G3. Both come with microSD slots for storage expansion.

The Samsung Galaxy S5 has a larger camera sensor

It's almost impossible to compare the camera's on the LG G3 and the Samsung Galaxy S5 without having reviewed them both but in terms of numbers, the Samsung Galaxy S5 offers a 16-megapixel rear camera in comparison to the LG G3's 13-megaixel snapper.

We thought the Galaxy S5 offered good camera performance when we tested it but we weren't as impressed with the LG G2 so hopefully the LG G3 will offer some improvements.

Both the LG G3 and the Galaxy S5 offer their own camera features with the Galaxy S5 having a very fast autofocus along with a selective focus mode and the LG G3 adding a laser auto focus and some exciting software tricks like a hand movement to take a selfie meaning you won't have half an arm in every one.

You will be able to capture 4K video on both devices and when we get the LG G3 in for review, we will let you know how we think the image quality compares to the Galaxy S5.

If you are interested in video calling or selfies, the LG G3 and Samsung Galaxy S5 both offer a 2.1-megapixel front-facing snapper.

The LG G3 has a bigger battery capacity

All the usual connectivity features are available on both the LG G3 and the Samsung Galaxy S5 so this section isn't likely to sway you one way or another either, but the battery is slightly bigger on the LG G3.

The Galaxy S5 offers a 2800mAh battery capacity compared to the 3000mAh found in the LG G3 so the numbers would suggest you will get a little more life out of the latter handset, but we will test this when we get it in for review.

We were impressed with the Galaxy S5's battery life and so we will be expecting good things from the LG G3 too.

Conclusion

From the specs, these two devices sit pretty neck-in-neck aside from the larger and higher resolution display on the LG G3.

The designs are quite different so it's likely you will immediately prefer one over the other and given that they have the same processor, storage and connectivity, there aren't too many other factors that would tip the seesaw in a either direction.

If it's a 2K display you want then the LG G3 is the device for you and you get a slightly bigger battery capacity with that too.

However, if you are into the sensor and fitness craze then the Galaxy S5 is probably your bag as you get the fingerprint sensor and heart rate sensor, along with a few more megapixels on the camera. Decisions, decisions.
