According to Murtazin, the 2100mAh battery on the original Samsung Galaxy S III will be replaced with a 2400mAh cell. The tweet also hinted at an improved display, although it was not said how Samsung would achieve this. It could be a higher resolution panel that will be on the refresh version of the device, we just don't know at this time. Additionally, wireless charging will be enabled.
It all sounds good, but we're pretty sure that Samsung has something more urgent to talk about for now.
