By moving from the Galaxy S III’s 2100mAh battery up to 2600mAh for the Galaxy S 4, Samsung assured that we’d be paying close attention to just how long the GS4 would function on a single charge; will there be improvements as substantial as those numbers imply? We’ve got some new battery torture-test figures to check out, and from the looks of things, the GS4 really will deliver on those promises of a longer battery life.
While the results are generally quite good overall, it’s not a slam dunk; no matter what test we’re looking at, there are always models that will outperform the GS4. For instance, it’s hard to beat the RAZR Maxx with its 3300mAh cell. Additionally, some phones with smaller batteries beat out the GS4 in specific evaluations, like how the HTC One can squeeze an extra hour out of its battery life while browsing the web.
Still, in tests like talk time and video playback, the GS4 outlasts the One, which is sporting a 2300mAh battery. It also beats the iPhone 5 at video playback, thought the iPhone wins out when web browsing. Based on these results, GSM Arena believes that even heavy users should get through a day of GS4 use without bottoming out their batteries, and casual users may even get several days of use on a charge.
These tests were done on a Snapdragon-600-running GS4; we’re especially curious to see how they might hold up against a GS4 running an Exynos 5 Octa.
