Battery tests for Exynos 5 Octa powered Samsung I9500 Galaxy S4 complete, here are the results
Not that 11 hours of talk time on a single charge we got from the Exynos S4 is bad, but a difference of over 60% is massive.
The web browser test gives the CPU something to do, but the result comes out almost equal – there’s less than half an hour advantage for the S600 model. Our web browser test is more intensive than casual browsing, so you might be able to squeeze out more than 7h of browsing out of the I9500 Galaxy S4.
Surprisingly, video playback also went in favor of the I9505 and by a full hour, too. It’s still in the Top 5 (the iPad mini doesn’t count since it’s a tablet), but since we test with an SD video, the chipset would have been anything but heavily loaded. Perhaps a more efficient hardware video decoder in the Snapdragon trumps the power saving of running on Cortex-A7s.
Standby power usage turned out to be about equal for both versions of the Samsung Galaxy S4, but the extra endurance the Snapdragon-based I9505 had in the three tests give it a higher endurance rating. The I9500 and its Exynos 5 Octa chipset scored 65 hours, down from 69 hours for the I9505.
The endurance rating shows how long a phone can last between charges if you do an hour each of calling, web browsing and watching videos. In practice, both versions will probably give you about the same time between charges as the battery of the I9505 will be very low over those last 4 extra hours.
