LG G Flex 2 vs Sony Xperia Z3 vs Samsung Galaxy S5: A specs comparison
Well, Happy New Year to us tech-heads – LG has officially announced the LG G Flex 2 – it was speculated and rumored about, but we had no idea how it would look. Well – it's gorgeous!

The successor to the curved, flexible G Flex from 2013 brings a smaller, yet – finer display – with a 5.5" diagonal, housing a 1080 x 1920 resolution (400 PPI), and boasts Qualcomm's latest flagship SoC – the 64-bit, octa-core Snapdragon 810 in strides to successfully carry the baton throughout 2015.

Of course, after such an announcement, we are itching to compare its specs to some of its competitors. Unfortunately, 64-bit capable flagships are yet to come out en masse, so we're forced to look back on some of the better performers from last year.

Well, let's grab one from the first half and one from the second half of 2014. The former device is going to be – you guessed it – the Samsung Galaxy S5 – an all-rounder, brim-packed with features and powerful hardware. The second contestant is going to be Sony's beautiful Xperia Z3 – released just 3 months ago, this flagship impressed us with an excellent battery life, and its snappy performance is no doubt assisted by its respectable specs.

So, let's check them out side by side!

IP certified

IP certified - The IP code indicates the degree of protection against dust and water. The first number represents dust protection, while the second represents water protection. In IP67, for example, 6 means a completely dust-tight device, while 7 means the device can stay immersed in up to 1 meter of water for up to 30 minutes. In IP68, a higher level of water protection is expected, but exact numbers aren't specified: both depth and continuance are specified by the manufacturer on per device basis.

Pixel density

Pixel density - The pixel density of a display represents the number of pixels over an area of one inch. It’s measured in “pixels per inch”, or ppi. The higher the number, the more detailed and good-looking the display is.

403 ppi424 ppi432 ppi

Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Current AMOLED screens differ in such a way that they can exhibit much more saturated colors (sometimes too much) and incredibly high contrast levels, which is due to black color being completely black in AMOLED displays.

Aperture size

Aperture size - The aperture of a camera is the opening through which light travels before it reaches the camera sensor. The smaller the number is, the bigger this opening is, allowing for more light to pass.

Focal length (35mm equivalent)

Focal length (35mm equivalent) - The lower (shorter) the focal length number, the wider the shot will be. Conversely, longer focal length cameras produce narrower frames, which can be used for telephoto (zoomed-in) purposes.

System chip

System chip - Most modern handsets use an advanced chip that includes many of the device’s hardware modules like the processor, Wi-Fi, Bluetooth and sometimes even the wireless radio. This field shows what particular system chip (or System-on-a-Chip) is used in the phone.

Qualcomm Snapdragon 810 MSM8994Qualcomm Snapdragon 801 8974-ACQualcomm Snapdragon 801 MSM8974-AC

Processor - The processor is the main computing component of a phone and is a major factor when it comes to the overall speed of the device. Some more powerful smartphones use dual-core and quad-core processors designed to deliver greater performance.

System memory

System memory - System memory, or RAM memory is the type of memory that the device uses to temporarily store data from the OS or currently-running apps. The more RAM available to the device, the better the performance will be when multiple or heavier programs are running.

Built-in storage

Built-in storage - Bigger storage capacity allows you to keep more content saved onto your device, such as more applications, photos or video. Games and video content typically take up the biggest amount of storage space.

32 GB16 GB32 GB
Storage expansion

Storage expansion - Some handsets allow you to expand their storage capacity by using a memory expansion card – most often microSD. Expansion memory is mostly suitable for media storage, such as photo, video or music content.

It makes you realize that specs kinda don't matter as much as they did 2 years ago... Its why I think there's no point in really buying high end phones when you have more than capable mid rangers out there that are capable of going the mile.

Aye. Snapdragon 810 has specs, that apps dont use at all in 2-3 years. In that time other features and a phone itself is already old. Only thing that might use such specs are hardcore shootem games. The big question is, who in earth plays them with a phone?? If I want to play them, I will grab my desktop and quality keyboard + mouse.

This spec hype these days is total nonsense. The same goes with curved display. Who does such feature in a phone??

totally agreed. The spec wars have ended. It makes more sense buying last years flagship phone which in a lot of cases is no more than 9 months old and saving yourself lots of money while experiencing hardly any performance hits.

Same thoughts here. Hardcore gamers will still go for PC or console units. As a consumer and Z3 Compact user, I already reached the threshold for desiring an ultra highly spec'ed phone. I just want phone manufacturers to offer better battery life and removable bloatwares.
