I’ve done a lot of complaining about smart phone battery life lately, and it seems like everyone’s working to improve that sort of thing. For example, Thursday, I was at a Star Wars movie marathon. It started at 3 AM, and I got there at 1:30 AM to make sure I got the seat I wanted and to be prepared for a staggering 18 hours or so of Star Wars movie. In order to make it through the whole thing, I had to turn my phone off between movies (and I wasn’t the only one, all of the neighbors we had around us did the same thing).
Sony has a battery with 40% more capacity coming to market in 2020. Unlike other cases, Sony is actually changing what goes inside batteries, adding sulfur into the mix to increase battery capacity without increasing battery size. Magnesium and sulfur is what’s in one battery; the other battery is lithium and sulfur. The sulfur apparently helps increase capacity by taking over for the positive terminal. Fittingly, the first devices that will be fitted with the new batteries will be smartphones, which should surprise no one at this point.
