Samsung I9300 Galaxy S III Jelly Bean battery life test concludes, see how it did

The Samsung I9300 Galaxy S III Jelly Bean update is finally seeding and we already got our office units updated. Our review of the 4.1 Jelly Bean and TouchWiz combo is already available and you can learn all there is to know about the updated Samsung flagship right here.

Meanwhile we finally competed our battery test on the Jelly Bean-powered Galaxy S III and we are ready to share the results with you. As it turns out Samsung has managed to squeeze even more endurance out of that 2100 mAh battery pack after the update.

The 3G talk time ended up the same as with the ICS-running Galaxy S III and is one of the best performers we have seen. With the screen kept off as per our usual call-testing procedures, the Jelly Bean S III survived for 10 hours and 15 minutes of constant talk on a single charge.

The web browsing hasn’t been a battery-friendly task for the AMOLED phones and the Galaxy S III is no exception. Back in the days when it was running ICS, the Galaxy S III depleted a fully charged battery in 5 hours and 17 minutes, but once it got Jelly Bean, it managed to better that achievement by an hour and 10 minutes. 6 hours and 27 minutes is still some way off the best we have seen, but the progress a single software update brought is downright impressive.

The video playback is the only place where the Jelly Bean S III falls behind the ICS unit – the battery reached 10% charger 9 hours and 27 minutes after we started the test – that’s 34 minutes less than the ICS Galaxy S III managed. We guess the Project Butter is to blame – the Jelly Bean eats more GPU power than the ICS and that might have affected the results. Still it’s an impressive results compared to most of the smartphones out there and the AMOLED is the one to thank for.

The major difference comes with the improved standby time. While we are not usually comparing standby times, they are already part of our formula for the final score. So, even with the other results being close to the ICS ones, the standby overall improvement pushes the endurance rating even higher.

Samsung Galaxy S III running on Jelly Beangot an endurance rating of 50 hours (7 hours more than the ICS Galaxy S III), which means you’d need to charge it once every 50 hours if you do an hour of 3G talking, an hour of video playback and an hour of web browsing each day. That’s quite an achievement, but keep in mind that your mileage may vary if you have different usage patterns.
