Now the folks over at GSM Arena have run some tests on the Samsung Galaxy S3 to see how its battery stands up against common tasks. The good news is that the 2,100mAh battery provides a decent amount of usage on a single charge. Let’s take a look at the results.

Starting off with 3G talk time, the Samsung Galaxy S3 does 10hrs and 20mins, only getting beaten by the Motorola DROID RAZR MAXX and Samsung Galaxy Note (have 3,300mAh & 2,500mAh batteries respectively). It manages to outdo the Apple iPhone 4S (7hrs 41mins) and its predecessor, the Samsung Galaxy S2 (8hrs 35mins).

Next up is web browsing where the results are somewhat mediocre. The Samsung Galaxy S3 survives 5hrs 17mins which is disappointing when compared to the iPhone 4S (6hrs 56mins). However it falls in at around the same time frames as the HTC Sensation XL, Samsung Galaxy Note and HTC Rezound.

However where the Samsung Galaxy S3 really shines is in video playback. The Galaxy S3 lasts a whopping 10hrs and comes in at number two, just below the Motorola DROID RAZR MAXX.

Overall, the Samsung Galaxy S3 should get you through a day of moderate usage without having you to run to a charger. It doesn’t employ a companion core like the Tegra 3 in the HTC One X to conserve battery usage however there are other measures in place to make sure the quad-core processors don’t suck up all the juice.
