Sony Xperia Z2 vs LG G3: Full spec comparison

LG has just released its flagship LG G3 smartphone, in a worldwide launch event that looks to be one of the biggest of the year. So how does the LG G3 stack up against its competitors in the high-end smartphone market? Let's take a look at it in comparison to Sony's impressively high-end Xperia Z2.

Let's break down the specs and take a look.

Size, weight and display

In terms of size and weight, the LG G3 and Sony's Xperia Z2 could be twins. With the Xperia Z2 weighing in at 158g next to the G3's 149g, there's barely a thing between them in terms of heftiness. The length and width are pretty similar too, with Sony's smartphone packing 146.8 x 73.3mm compared to the LG G3's 146.3 x 74.6mm.

However, the thing to realise is that LG is packing a 5.5in screen onto a phone exactly the same size, whereas the Xperia Z2 has only got a 5.2in face. That means the bezels on the LG G3 are pretty damn tiny. Not to mention that the display on the LG G3 is startlingly clear. Usually a larger screen means less pixel density, but the 2,560 x 1,440 pixels resolution on the G3 is going to bring an astonishing 534PPI - dwarfing the 423.64PPI of the Xperia Z2, which itself was praised for image clarity at its release. This could be the real game-changer between the two.

The Xperia Z2 manages to slightly pip the LG G3 on thickness, though - the svelte Sony smartphone is only 8.2mm thick, compared to LG's 8.9mm. But they're both pretty thin as phones come, so you're not really going to notice this a lot.

Processor, battery and storage

In processors, too, there's pretty much nothing between these phones. Both pack the latest Snapdragon 801 with at least a 2.3GHz processor, and while the Z2 comes with 3GB RAM, the LG G3 can be bought with just 2GB.

LG has packed its new G3 phone with a whopping 3,000mAh battery, but that's still no match for the Xperia's 3,200 mAh one. Also, remember that the G3's enormous screen is going to be quite a power-hungry beast, so the Xperia could be the smart choice on this front in the end.


The camera is where the Xperia Z2 really makes gains on the LG G3. While LG has packed a very respectable snapper under the hood, with a solid 13 megapixels, the Xperia Z2's immense 20.7-megapixel camera is the clear choice for photography buffs who want to use their phone as a camera. The Xperia even packs an extra 0.1-megapixels into its front-facing selfie camera, although that's not a difference you'll cry over.

The LG G3 is packing some impressive camera software to make up for its lack of megapixels, though. Features like OIS+, laser autofocus and dual-LED flash, as well as a new 'Touch & Shoot' camera UI put it well ahead of what you might expect from 13-megapixels, so the difference won't be as pronounced as you might imagine.


The LG G3 is an impressive offering, and maybe of all the phones released this year has finally given the Xperia Z2 a run for its money. Advantages such as its larger screen on a same-sized body, as well as its astonishing clear picture quality could just prove the factors that seal the deal for people who truly care about display.

You could never accuse Sony of releasing a cheap smartphone, either, and the Xperia Z2 - while impressively high-end, does come with a hefty £599 price tag. Still, the Xperia is still a fantastic choice for smartphone users who want only the best, at any price.
