The battery-life from the new models of cell phones are underperforming their previous models, Washington Post tech columnist Geoffrey Fowler writes.

The details: Fowler performed the same battery test for 13 phones and his findings show battery life doesn't match up to what phone makers advertise. The new iPhone XS died 21 minutes earlier than last year’s iPhone X. Google’s Pixel 3 lasted nearly an hour and a half less than its Pixel 2.

The Scottish tidal energy developer Nova Innovation has teamed up with Tesla to demonstrate the world’s first tidal energy storage system (TESS). Tesla is no stranger to the renewable energy market, but this is the company’s first foray into tidal energy.  

Why it matters: While this is a relatively small-scale project for a national grid, it could have big implications for coastal microgrid designs if it proves successful. The integration of technologies that can produce tidal energy with those that can store it makes a powerful combination, potentially providing consistent and reliable baseload power from a renewable energy source.
