11Hrs is among the top. It will give about 24-30 hrs for moderate usage for me.

Question by Romulus: How do I turn on 4G on on samsung s3?

It's always on. You just aren't in a 4G area believe it or not. In fact, you CANT turn 4G off. There is a leaked modem firmware version that significantly improves signal (I'm running it now) that should be pushed to your phone when Verizon updates the s3 to jelly bean. I in the mean time, wait (or root your phone). But if you don't get 4G anywhere, then there just isn't 4G there. It's not always the phone. Or you could try to just reboot your phone.

  1. We ran a 90 minute video at full brightness and applied all accounts (Dropbox, Facebook, Twitter, Exchange etc) and set them all to the most regular updates over Wi-Fi.

    The Samsung Galaxy S3 managed to get to only 82% battery power by the end of the test – compare that to the 60% of the HTC One X and 74% of the iPhone 4S and you can see why we’re impressed.
    Under heavy load, the phone will last about 8 hours. And we mean heavy: the battery test we mentioned plus an hour of photography and video. After than half an hour of playing Riptide GP and then some web browsing for a further hour. Then around twenty minutes of music listening before an hour’s session on video.
    We also had the voice-control activated from the lock screen the whole time, which Samsung tells you is a real battery killer as it listens to what you say.
    This pushed the battery to about 20%, after which we killed it trying to synchronise over Wi-Fi direct in about 45 minutes (although this can be a real battery drainer).
    In real use, as in not checking it every seven seconds to play with it (the curse of the new phone) you’ll get a much more reasonable battery life. We regularly saw power drops of only 30% by 2PM, and a healthy 25% by bedtime.
    This will change during use, obviously, but it’s much harder to hammer the battery through actually doing things the phone is supposed to compared to the HTC One X.
    This has also been improved by the software update AGAIN. While some days saw the battery meter swing a little bit lower than usual on the odd day of hardcore usage – this was improved and since updating we haven’t gone lower than 25% at bedtime. Excellent work, Samsung.

    If you’re one of those people that want to have the phone all their friends have got, then the Galaxy S3 is the one you better hope that they have.
    When it comes to connectivity, it’s unsurprising that the Samsung Galaxy S3 is fully stocked – in fact we can’t think of a single thing that we’d want to see that’s missing.
    From NFC to advanced location sensors, everything has been packed into the 8.6mm frame.

    Samsung has built on the Android Beam system – based on NFC – that Google created to allow users to share things like map directions, web links and YouTube videos. However, it’s souped it up by using Wi-Fi Direct, which can transfer items at dizzying speeds.
    Think pictures from one phone to another in seconds, and HD videos in around a couple of minutes – although sadly the trick will only work from S3 to S3 at the moment – we’re hoping Samsung changes this in the future as Wi-Fi Direct connection should be easy to do between brands.
    Dual channel bonding is also on offer for the Wi-Fi brigade out there – we noticed very little in the way of slowdown when it came to connecting over Wi-Fi, and the signal strength held well even with our crappy Sky router (which loves to spit out a single bar of reception even when right next to the box).
    Samsung hasn’t stopped there though – get yourself a MHL lead and connect up to the TV through the microUSB port and you can mirror your device onto a larger screen with no problems… and it’s a much better way of using your phone as a games controller than going through AllShare Cast we’ve found.
    USB To Go is an underrated trick that we’re surprised isn’t being more widely used (although it’s probably because the adaptor is so jolly hard to get hold of) – being able to connect a USB stick or hard drive to the phone when out and about is a great feature to have and one we’re glad to see again.
    GPS is on board, and it’s backed up by GLONASS – for those that don’t know, this is a system that’s similar to GPS (developed by the Russians) that’s slightly less accurate than the US-created version – but add the two together and you’ve got a superbly quick fix when it comes to locating yourself on the Maps app… we’re talking a couple of seconds max most of the time and world away from the rubbish reception of the Galaxy S2.
    (Apparently GLONASS is necessary on mobile phones now to avoid being subject to an import duty when exporting to Russia – we don’t care, as it gives us faster tracking and phones are cheaper for our Russian friends. Everyone wins).

    As we’ve already discussed, DLNA is on board to allow easy connection to nearby devices – most of the time you’ll have to trigger this manually in the menu, but once enabled the streaming is pretty quick.
