In Pictures: What to expect from the world’s biggest mobile show – MWC 2013

Broadcom’s power-saving GPS chip

Broadcom’s BCM47521 can power all kinds of location-based apps without draining your phone’s battery through frequent, constant location checks. The trick: the chip handles a bunch of tasks on its own, instead of calling for help from the phone’s main processor and memory. The chip cuts the power needed for location-based services, such as geo-fencing or turn-by-turn navigation, but up to 60T, according to Broadcom. It will start appearing in smartphones by mid-2013.
