Samsung Galaxy S III vs. Note II: Sizing up

Battery life endurance race

The Samsung Galaxy S III and Galaxy Note II both use virtually the same chipset, though the one in the Note II is clocked higher. There is a tangible difference in screen sizes too, the bigger 5.5" Super AMOLED screen is more energy-intensive.

To make up for it, the Note II has nearly 50% more juice in its 3100mAh battery than the Galaxy S III and its 2100mAh battery.

The screen doesn't come into play in the first test - the call test - and neither does the faster clock speed. The Note II can last nearly 17 hours of talks on a 3G network, which is considerably more than the 10 hours 20 minutes that the S III scores (updating it to Jelly Bean doesn't help).

That's 65% better, more than the difference in battery capacities, so we might be seeing a more efficient modem or antenna on the Note II.

The Galaxy Note II maintains its lead in the web browsing test, with an advantage of just over two hours over a Jelly Bean-running Galaxy S III. If the S III is running Ice Cream Sandwich the gap is even bigger - three and a half hours. Running the newer Android release has clear advantages.

In some cases, anyway. When it comes to playing videos, the Galaxy S III manages 10 hours on Ice Cream Sandwich and half an hour less on Jelly Bean. The Note II beats it either way, though with the narrowest margin of the three tests, an hour and a half/two hours.

In the end, a Samsung Galaxy S III will be good for two days of usage during which you can do an hour of talking on a 3G network, browse the web for an hour and watch an hour of video each day.

The Galaxy Note II will last nearly a day longer with a similar load.

While both devices have good battery life readings, really heavy users will be better off with the Note II, especially if they do a lot of calling. The Note II also offers more comfortable reading of web pages and a better viewing experience with its bigger screen too. And since we run tests with the screen set at 50%, the Note II's screen was brighter during the tests.
