Samsung Galaxy S Duos battery tests are complete, results are inside

Dual-SIM phones are still relatively rare and usually limited to the low-end, but the Samsung Galaxy S Duos takes after the Galaxy S III mini in terms of looks (though not in terms of specs, unfortunately).

Dual-SIM phones are usually bought when there are no good plans available – ones that offer enough talk time, texts and data. So, how long can the S Duos last if you need the second SIM for even more talking?

With a time of 8 and a half hours, the Galaxy S Duos manages to outlast its Galaxy Ace Duos cousin, even though it doesn’t have much of an advantage in the battery department – 1500mAh for the S Duos and 1300mAh for the Ace Duos. This is also an hour more than the official specs promise (those are usually conservative).

The web browsing test was done over Wi-Fi and the phone lasted around 5 hours and 20 minutes. It’s a bit better than what the dual-SIM Ace did, which is pretty good considering the Galaxy S Duos has a larger, higher-res screen (4″ vs. 3.5″ and WVGA vs. HVGA).

The video playback time of the S Duos was disappointing at 4 and a half hours, which is two hours less than the Ace and puts the phone towards the bottom of the chart. It’s worse than the performance of the HTC Desire V – another dual-SIM droid with almost identical specs.

After running the calculations, the endurance rating for the Samsung Galaxy S Duos works out to 43 hours, barely better than what the Ace Duos got, but a bit less than the Desire V score.

This is partially due to the poor video playback performance. If all you do is call, the S Duos should offer very decent battery life. The web browsing time is average but should be used with caution, especially if you got the second SIM for its data plan.
