The Galaxy S6's 2550mAh battery capacity might not seem like too much at first but Samsung has made many other tweaks to ensure that users can get the best possible performance out of their device before it needs to be charged again. We had exclusively reported back in November last year that the Galaxy S6 is going to come with Broadcom's BCM4773 chip. This special localization chip enables the Galaxy S6 to collect and compute data from Wi-Fi, Bluetooth and GPS modules on one single chip which results into far less battery drain.
Tweakers was able to confirm at Mobile World Congress 2015 that the Galaxy S6 indeed touts Broadcom BCM4773 and estimates that compared to existing solutions this chip provides power efficiency of up to 80 percent. This will go a long way in ensuring that the 2550mAh battery in Samsung's latest smartphone can last even longer.
