Sony's current lithium ion battery TOKYO -- Sony plans to introduce a new high-capacity battery in 2020 that will enable smartphones and other devices to run 40% longer, aiming to stake out a larger share of the battery market.
High-capacity batteries provide longer run times for smartphones and other devices while taking up the same amount of space. Sony's version could power the latest Apple iPhone, the 6s, for 14 hours while the device is connected to the Internet, calculations show. Batteries could also be made 30% more compact while maintaining current run times, letting manufacturers build smaller devices.
