Samsung Galaxy S3 Battery Life Secrets

Samsung has played modest with battery life predictions for the Galaxy S3, but even with a quadcore processor onboard, pre-launch feedback suggests the Korean company could have achieved the impossible. Going by some early figures from insider EldarMurtazin, the Galaxy S3’s 2,100 mAh power pack is good for over 20hrs of runtime with 42-percent of juice still to go.


According to a latest comparison between this phone and other devices, usage includes around five hours of audio playback, a dozen photos and a single video. However, it’s also worth noting that cellular radio use was minimal – only an hour out of the total time active, with the rest presumably being a combination of WiFi and Airplane Mode.

That implies that a normal day of functionality should be possible, on a par with other flagship Android phones of the moment.


Unsurprisingly, the Samsung’s display – a whopping 4.8-inch HD Super AMOLED running at 720p resolution – is the major cause for battery draw, comprising 71-percent of the total power consumption. That majority status is unlikely to change even when the radios are turned on.


Samsung expects to launch the Galaxy S III in Europe from May 29, with North American variants toting LTE planning for the Summer.
