Asus ZenFone 5 vs Samsung Galaxy S4 vs LG G2: specs comparison

Asus ZenFone 5 vs Samsung Galaxy S4 vs LG G2: specs comparison

Asus hasn't had a serious smartphone offering for quite a while now (that's if we don't count the Padfone, and we don't), but it seems like the time has finally come for the manufacturer to unleash a brand new handset line. Enter the ZenFone! Asus' latest family of smartphones includes three models - the ZenFone 4, ZenFone 5 and ZenFone 6, none of which being particularly high-end, but the 5" and 6" models shaping up as quite decent upper mid-range packages with their 720p displays and Intel CPUs.

Anyways, let's take a look at how Asus' new ZenFone 5 — which can be considered the most mainstream product of the trio — fares against some formidable opponents such as the Galaxy S4 and the G2. Naturally, since we're comparing it to two flagship devices, the ZenFone 5 will understandably lag behind its opponents in the specs race, but if you think about it, that's still going to be quite an interesting comparison, as it's going to give us a hint of just how close to last year's premium experience one can get with this new crop of affordable Android smartphones. After all, the ZenFone 5 is expected to be priced at $149 off contract, making it quite an alluring proposition.

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.

294 ppi441 ppi423 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.

Camera sensor size

Camera sensor size - A bigger camera sensor is able to capture more light, and thus produce better photos.

Pixel size

Pixel size - The size of an individual pixel on a camera's sensor. The bigger, the better.

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.

Intel Atom Z2580Qualcomm Snapdragon 600 8974Qualcomm Snapdragon 800 MSM8974

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.

Graphics processor

Graphics processor - The graphics processor is important for the smooth operation of the system and especially in games and other applications that may involve complex graphics and animations.

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.

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.

Capacity - The bigger, the better! However, battery capacity is not the only factor that has an effect on battery life. Those include the chipset in use, the software running on the device, as well as the consumer's unique usage pattern.

Unfair!! Two of the above phones cost more than thrice as much as the third one!! Compare it to Moto G or Galaxy S Duo 2 or Optimus L5 II!!

These phones are not in the same level. The Zen 5 obviously sucks comparing to the other two. It's a nice phone pricewise though. Comparing it to some cheapo phones would make more sense.

Asus should have made it a highend phone with 1080, 2800-3k battery, and 2-3 gb of ram.

No, I see the point. It's to get it into as many hands as possible. But I would actually like to see a higher spec'd version of the phone. It actually seems kinda nice.

Unfair! Galaxy S4 looks cheap & ugly. But ZenFone 5 looks premium & well designed

Ummmm, I thought that ZenFone won't be here. You know Asus has a bad reputation is smartphone race. It's Android race, not PC motherboard. Lol.
