Benchmark tests from South Korea are in, measuring the new LG G2 against its premium smartphone competition.

When LG Electronics announced its flagship device, the LG G2, among the many high-powered specs that the company revealed was a 3,000 mAh battery, which is more than ample for a 5-inch handset. But you never know what the actual battery life of a device will be until you test it. So recent tests of the LG G2, which come out of South Korea, will give you a good idea of how LG's new device stacks against the competition. The results are mixed.

The first thing to note is that the tests were performed with the Korean model of the LG G2, which features a smaller, 2,610 mAh battery. However, there is virtually no difference with other hardware in the handset, so GforGames calculated the adjusted results to show how the U.S. release of the LG G2 will fare.

First is web surfing, using WiFi, on the handset's default browser. In this test, even with the smaller battery, the LG G2 did a spectacular job, beating the Samsung Galaxy S4, Apple iPhone 5, and every other device, except for the Galaxy Note 2 on 100 percent brightness (the orange line). At 70 percent brightness (the blue line), the iPhone 5 lasts almost 30 minutes longer, but the LG G2 still beats most of the competition. (Test results are cropped, go to GforGames for the full list of devices tested).

GforGames' calculations show that the U.S. LG G2 will be able to browse the web on a WiFi connection for about six hours and 41 minutes at 100 percent brightness, and at least nine hours at 70 percent, blowing away the competition (except for the Galaxy Note 2 at 100 percent brightness).

On other battery tests, the LG G2 didn't do as well. For video playback, measured playing Avatar on the phones' default players, the LG G2 gets beaten by the Galaxy S4, Note 2, and almost by the 2012 Samsung Galaxy S3. Still, with a 3,000 mAh battery, the LG G2 will get about eight hours and 26 minutes of video playback at 100 percent brightness (orange) and about nine and a half hours on 78 percent brightness (blue). That's maybe not the best, but it certainly gives you enough time for a couple movies.

Finally, the LG G2 was tested for battery consumption using 3D apps - benchmarking with GLBenchmark 2.5 Egypt HD.

This is where the LG G2 fails to compete (though the iPhone 5 performed even worse), lasting only two hours and 16 minutes, which puts the U.S. release model at about two and a half hours. That may be just bad optimization, and perhaps LG can fix it before it gets a release date in the U.S., but maybe gaming is just not for the LG G2.

The LG G2 was unveiled last week in the U.S., packing a 3,000 mAh battery to power a new quad-core Qualcomm Snapdragon 800 system on a chip, clocked at 2.26GHz. It comes with 2GB of RAM, a 5.2-inch 1080p Full HD display, and a 13-megapixel main camera. The device runs Android 4.2.2 Jelly Bean out of the box, and will be hitting the shelves of over 130 carriers across the world soon. Keep with Latinos Post Tech for more information on the LG G2, as it continues to come closer to a release date for the U.S.
