What does this mean? The international or global variant might or might not feature the same battery as the one powering the device we’ve recently seen leaked in pictures and a video. However, if it will, it will be powered by a 2,600mAh battery.
According to the image above, the battery inside the GT-I9502 is one of 9.88Wh (watt-hour). Thanks to a neat formula (mAh = Wh x 1000 / V or milliamp-hour = watt-hour x 1000 / V) we find out that the battery is rated at 2,600mAh (9.88 x 1000 / 3.8).
This is a step-up from the 2,100mAh battery on the Galaxy S III but let’s not forget that about every internal aspect of the phone is expected to be bumped over last year’s model, including the screen and the processor, which are the main battery drainers.
Of course, there’s a chance that this specific Chinese version needs more power to keep two SIMs active and the phone connected to two networks but still…
