Samsung might be working on a refreshed Galaxy S III (http://www.gsmarena.com/samsung_i9300_galaxy_s_iii-4238.php) edition with a better display, a bigger battery and wireless charging. Reportedly, the new battery capacity will be 2400 mAh - 14% more powerful than the original unit.
There is no info on what "better display" means, while the wireless charging is self-explanatory.
The information comes from Eldar Murtazin, who despite not having the best of rumor records recently, accurately leaked March 14 as the Galaxy S IV (http://www.gsmarena.com/samsung_i9500_galaxy_s_iv-5125.php) announcement date.
If you followed Samsung closely, you'll already know the manufacturer has a tradition of refreshing its old flagships. It has already done this twice with the original Galaxy S (Plus (http://www.gsmarena.com/samsung_i9001_galaxy_s_plus-3908.php) and Advance (http://www.gsmarena.com/samsung_i9070_galaxy_s_advance-4469.php)) and the Galaxy S II (Plus (http://www.gsmarena.com/samsung_i9105_galaxy_s_ii_plus-5213.php)). So, if the Koreans were to refresh the Galaxy S III (which is their most popular smartphone to date), it probably won't raise too many eyebrows. We guess the updated Galaxy S III announcement will only happen after the Galaxy S IV hype has settled down a bit, though.
