A company called Somaltus LLC has filed a suit against Apple in the U.S. District Court for Eastern Texas. The company claims that the fast- charge technology used on the Apple iPhone 6s and “any similar device” sold by Apple, infringes on a 2010 patent belonging to Somaltus. With the fast-charge system on the iPhone 6s, charging speeds are maximized when the battery inside the phone drops under 80% capacity; above that level, the charger switches to a slower trickle charge.
Somaltus says that Apple’s fast-charge feature infringes on U.S. patent 7,657,386, called “Integrated Battery Service System.”
