With the new LG G2 powerhouse finally official, we can now compare it to other high-end flagships and see how it fares.

LG recently released its latest flagship and offered a full list of specs, which means that we can now compare it to other devices in its range. Here's how the LG G2 stacks up against the Sony Xperia Z Ultra, the Samsung Galaxy S4 and the HTC One.

Display

The LG G2 sports a 5.2-inch Full HD IPS display with a resolution of 1920 x 1080 and a pixel density of 424 pixels per inch (ppi). The Sony Xperia Z Ultra boasts a huge 6.44-inch Full HD Triluminous display with X-reality technology and a pixel density of 344 ppi. With that whopping 6.44-inch display the Xperia Z Ultra is in a class of its own and it's obviously the largest device in this comparison.

The HTC One, meanwhile, is the smallest, sporting a 4.7-inch Full HD display. Being smaller and Full HD, however, results in the highest pixel density among all four devices compared here: 469 ppi. The Samsung Galaxy S4 is the only smartphone here to use a Super AMOLED display. It has a 1920 x 1080 (Full HD) resolution on a 5-inch screen, which means a pixel density of 441 ppi.

In conclusion, all four handsets compared here sport very high pixel densities and it ultimately comes down to size and display type. Preferences will vary from user to user.

Processor & RAM

The HTC One and the Samsung Galaxy S4 made their debuts earlier in the year, so they come with the Snapdragon 600 chipset. Both of them use Adreno 320 graphics. The difference in terms of processing power lies in clock speed: the Samsung Galaxy S4 is clocked slightly higher at 1.9GHz, while the HTC One comes in at 1.7GHz.

The newer Xperia Z Ultra and LG G2, meanwhile, boast the very latest Qualcomm Snapdragon 800 and the new Adreno 330 graphics processing unit (GPU). The Xperia Z Ultra is clocked at 2.2GHz while the LG G2 is slightly higher at 2.3GHz.

This means that the LG G2 and the Xperia Z Ultra are faster in benchmarks, but the HTC One and the Samsung Galaxy S4 are still very powerful, fast and able to handle virtually any task with ease. All four handsets come with 2GB of RAM each.

Software

All four handsets run on Android 4.2.2 Jelly Bean, topped with their respective custom flavor. The Samsung Galaxy S4 has the latest version of the company's TouchWiz Nature UX, the HTC One comes with HTC Sense 5.0, The Xperia Z Ultra has the Sony Xperia UI and the LG G2 sports the LG Optimus UI. In other words, it ultimately comes down to users' UI preference.

Camera

The LG G2 has a 13-megapixel rear camera with optical image stabilization (OIS), LED flash, autofocus, and a 2.1-megapixel front camera. The Xperia Z Ultra comes with an 8-megapixel rear camera with autofocus and a 2-megapixel front-facing shooter. The Samsung Galaxy S4 sports a 13-megapixel rear camera with LED flash, autofocus and some neat features, being praised as one of the best smartphone cameras. The handset also has a 2-megapixel front camera. Lastly, the HTC One uses a 4-megapixel "UltraPixel" camera with LED flash and autofocus, as well as a 2.1-megapixel front camera.

Storage

In terms of memory capacity, the LG G2 comes in 16GB and 32GB flavors, the Xperia Z Ultra has 16GB of internal storage expandable up to 64GB via micro SD, the Galaxy S4 comes in 16/32/64GB configurations and supports micro SD cards of up to 64GB, while the HTC One comes in 32GB and 64GB flavors. In this category, the Samsung Galaxy S4 offers the most options, but its 16GB model was highly criticized for leaving too little memory actually available to users.

Battery

The LG G2 and Xperia Z Ultra both have 3,000 mAh batteries, both non-removable. The Samsugn Galaxy S4 has a 2,600 removable battery, while the HTC One packs a 2,300 non-removable battery. Based purely on specs, the LG G2 should offer the best battery life. The Xperia Z Ultra may have the same battery capacity, but it needs to power a considerably larger display.

Conclusion

In addition to its high-end specs, the LG G2 also sets itself apart from rivals with its unique Rear Key concept, sporting the volume and power buttons on the back of the device rather than on the sides, as usual. At the same time, the Sony Xperia Z Ultra has something that none of the other four handsets in this comparison have: water resistance. The Samsung Galaxy S4 received high praise for its great features and its eye-tracking technology, while many believe the HTC One sports the best design from any smartphone currently available on the market. In conclusion, all four smartphones are top-notch and boast high-end specs. Each of them has its own strengths. In due time, consumers' preference will make it clear which of the four handsets is the most popular.
