Early benchmarks show Samsung Galaxy S3 leading the pack in battery life. One X left in the dust

Still doubting that the battery inside the Samsung Galaxy S3 will have enough juice to comfortably run the flagship phone’s 4.8-inch SUPER AMOLED HD screen and quad-core processor? We have some good news for you, then. According to battery benchmark tests, Samsung Galaxy S3’s 2,100mAh battery won’t disappoint at all.

First, we’d like to turn your attention to one rather non-scientific evidence from blogger Eldar Murtazin, who recently posted a screenshot of his Samsung Galaxy S3’s battery usage. The phone’s battery was shown to still be 42% full, even after Murtazin supposedly used the phone for over 20 hours. According to him, he listened to music for five hours on the phone, amongst other multimedia usages, and used it on a 3G network for an hour, before making the switch to a WiFi connection.

The next set of proofs comes from the folks at GSM Arena, who have just concluded their own battery benchmark tests for the Samsung Galaxy S3.

On the 3G talk time test, which measures how long the phone can be used to talk on a single charge, Samsung Galaxy S3 lasted 10 hours and 20 minutes. This was good enough to beat Galaxy S2’s 8 hours and 35 minutes, as well as competitors like the HTCOne X, which clocked close 9 hours and 57 minutes. Motorola Droid Razr Maxx and its monster-size battery lasted 20 hours and 24 minutes.

The Samsung Galaxy S3’s SUPER AMOLED HD screen is proven to be quite detrimental for web browsing, but it still performed admirably. The phone lasted 5 hours and 17 minutes in the web browsing test, a good one hour more than HTCOne X’s performance. Again, the Droid Razr Maxx was king with 7 hours and 23 minutes.

Who doesn’t love to catch up on their favorite TV series while on the road or to avoid awkward conversations during lunch break? You’ll be pleased to know that the Samsung Galaxy S3 managed to last 10 full hours of video playback. Though it can’t beat Droid Razr Maxx’s time of 14 hours and 17 minutes, it almost doubles HTCOne X’s 5 hours and 45 minutes.

The Samsung Galaxy S3 may not be the absolute dream phone for everyone, but it’s apparent from the benchmark tests that its battery performance is something that Samsung has gotten right.
