 From ABC News Tech Trends, Samsung's smaller foldable phone, the Galaxy Z Flip, is adding some subtle but notable changes to its sixth generation. That includes a bigger battery, more RAM, and for the first time, a vapor chamber. The vapor chamber will keep the processor from getting too hot, and when processors get too hot, the performance goes way down, the battery life gets sucked up. Android Authority's C. Scott Brown says the updates don't stop there.
