Sony is developing smartphone batteries that last 40% longer

Don’t get me wrong, I like the power increase that comes with each successive generation of smartphones, but I’m far from alone when I say that I’d rather have a battery that lasts longer than an improved processor whose added power I probably won’t even utilize. Improving battery technology is much easier said than done, however, but Sony is one of the many companies that’s making an effort, and unlike all of those other breakthroughs and improvements we hear about that never actually make it to the market, the company is working on a sulfur-based battery that will actually be hitting the market. The batteries are claimed to last 40% longer than existing batteries, but the caveat is that they won’t launch until Sony has finished its extensive safety tests, which will take until at least 2020.
