Samsung I9082 Galaxy Grand Duos battery test is complete, here are the results

We already gave you our Samsung Galaxy Grand Duos review, but now it’s time to examine the battery life of the smartphone in great detail. You already know the final score, but let’s see how the different parts of the dual-SIM phone’s performance stand in comparison..

With a 2100mAh battery and a modest WVGA resolution you would always expect the Samsung Galaxy Grand to do well even if has a large 5″ screen to power and dual-stand-by to cater for.

Our first test is all about 3G talk time. We supplied the Galaxy Grand with two active SIM cards and did the test with each of them while the other is on active stand-by. The Galaxy Grand battery went flat after 12 hours and 45 minutes – an pretty good result overall, and the best we have seen from a dual-SIM phone.

The web browsing test saw the Samsung Galaxy Grand put in another solid performance, lasting for 7 hours and 9 minutes on a single charge. That puts it near the top of our chart – a commendable achievement for a smartphone with a 5″ screen, WVGA or not.

When playing videos the Samsung Galaxy Grand did managed to last for a whole hour longer compared to web browsing. Enduring 8 hours and 11 minutes before 90% of the battery charge was gone (this test end earlier than the other two), was enough to secure a good mid-table position.

Given the solid good job in the individual challenges, it was no surprise that the Samsung Galaxy Grand got a great 56h overall endurance rating. Surprisingly, or rather not with a battery this big, even the dual stand-by didn’t affect its stand-by efficiency too greatly . This means you’ll need to charge the phone every 56 hours if you use it for an hour of 3G talks, video playback and web browser each day.
