Both Apples iPhone 4 and iPhone 4S pack in more pixels (326ppi apiece) than the S3 does, but arguably the two iOS devices need sharper resolutions since their screens are a lot smaller (3.5 inches). One area where the S3s screen did not knock my socks off was under direct sunlight.

Samsung Galaxy S3 Review Full Days Worth

So provided you dont insist on dialling the screen up to max brightness, you should eke a full days worth -- circa 6 or 7 hours -- of video streaming on a single full charge.

I also gauged the S3s battery using Antutus battery benchmark, which tests battery performance over several hours.

The phone lasted 1 hour 12 minutes on part one of the test, dropping from 100 per cent battery to 73 per cent.

It endured 1 hour 9 minutes on the second part, dropping from 73 per cent to 46 per cent.

Overall, on the Antutu battery benchmark, the S3 scored 597, beating the HTC Incredible S, Motorola Milestone, Samsung Galaxy S2 and the LG Optimus 2X, among other devices.

It was beaten by the Motorola Xoom tablet and the Acer Iconia Tab A500.

The One X failed to run this test.) Expect to charge the phone every night -- or sooner if youre using it a lot or revving its engines too much.

Its also worth noting the S3 is quite slow to charge over USB.

If you need a lot of power quickly, youll have to find a wall socket to juice up.

Samsung has added a power saver mode to the S3 that can be customised to limit the maximum performance of the CPU, dim the screen, change background colour in email and the Internet and turn off haptic feedback.

Some would argue it had a perfect amount of pixels for a phone.

But while you might find your knuckles bending in new and exotic ways, the benefit is that this whopping display will make your photos and videos look stupendous.

This is an HD Super AMOLED screen, which is the same display tech used on the Nexus and Note, both of which are a real treat for the eyes.

But as with previous Samsung gear, if youre a fan of more demure, natural colour reproduction, then you might find this panel a little garish compared to the iPhone 4S.

Theres one minor downside -- the S3s panel is missing the Plus suffix that youll find on the Galaxy S2s Super AMOLED Plus display.

That means it has one fewer sub-pixel per pixel than the S2s panel.

Screen enthusiasts may be disappointed by this news, but I suspect most people will never notice the difference.

Its truly glorious to eyeball and has a very impressive viewing angle.

At times, as you tilt the phone away from you, the screen almost looks unreal -- as if its been printed on the surface of the phone.

Most people wont notice any difference in clarity and its entirely possible to read text on a full website such as the BBC News home page when fully zoomed out.
