You may recall our short editorial on the one thing the Galaxy S III needs to truly shine, that being a better battery life than similarly high-end devices. A screenshot from Russian blogger Eldar Murtazin shows just that: the new Samsung flagship his clocked at just over 20 hours of run time with 42% battery left. The battery on the Galaxy S III is 2100mAh, about 15-20% larger than most high-end Android phones.

Murtazin testifies that he’s used the phone for five hours of music, a dozen photos and one video, but there’s something that casts doubt on the impressive stat. He also said that he’d used it for only an hour on the cellular network, with the rest of his time presumably spent on local WiFi. (Note the WiFi and Airplane Mode icons in the status bar.) That skews these results somewhat. Samsung phones tend to get average to good battery life, with the notable exception of Verizon’s Galaxy Nexus LTE variant.

The Galaxy S III is set to release in Europe on May 29th, followed shortly by a UK release on the 30th. It will be sold in its HSPA+ version unlocked and via most major carriers. There’s no confirmed carrier for the United States just yet, but compelling evidence for Verizon and at least a suspicion of AT&T and T-Mobile versions are present. Samsung says that the Galaxy S III will be coming to North America later this summer.

    GSMarena has a good comparison too, says it beats out the One X.

      I have the Sprint Epic 4G Touch and I pull 28 hours on cell with sync on and 3+ hours of screen on time using the leaked Sammy ICS rom. So the gs2 with a bigger battery isn’t impressing me to much.

        Hmmm a rooted and rom’d phone getting better battery life than a stock non-rooted phone. Who would of thought that could happen…/s

    • will

      I wouldn’t say outstanding, I’d say better, taking into consideration the ICS Galaxy s2 comparison 

      Like 2 more hours talking time and video playback, for web browsing remains pretty much the same.

      • warcaster

        It seems to have 25% better battery life than GS2 in everything. 4 vs 5 hours of battery life is not “the same”. It’s 25% more.

      • will

        Maybe I’m missing something, but, the tests claim 
        S2, web browsing: 5:04H
        S3, web browsing: 5:17H

        so… again, for WEB BROWSING remains pretty much the same…

    One thing here is that the phone has the airplane mode active, that saves lots of battery. That’s what I do when I do not have signal.

  • Drognex

    I would be able to pull the same stats with my verizon gnex if i was just using wifi and aorplane mode was on.

    Ya I had great battery life with my vibrent when I stuck it in the micrwave and fried the antenna to send it for worenty. think I got like 3 or 4 days out of it watching movies and playing games.what I love about this potto is how much supper amoled sucks a big donky slong. you can see it takes up over 75% of the battery life and I bet the screen wasn’t even on the hool time. people a need to stop buying amoled any thing for phone or this crap will not stop.this is y I’m going to stock with my g2x for a wile. Samsung pleaser so making crappy phone you give Android a bad name.
