How DeepMind's biggest AI project is fixing bad Android batteries

In January 2014, Google splashed £400 million on buying the London-based artificial intelligence firm DeepMind. At the time, it wasn't clear what Google, and now parent company Alphabet, would get for its money. Four years later, DeepMind's team that focuses on developing AI for Google is starting to pay off. Google's launch of its latest mobile operating system, Android Pie, involves DeepMind's largest real-world machine learning roll-out to date. It's looking to solve one of the modern smartphone's most frustrating features: poor battery life.
