While there have been hints of advanced battery technology development reported in various journals, there was nothing even hinted at the Consumer Electronics Show in Las Vegas this week. This would suggest that we are still a very long way off from any commercial solution to our dead and dying batteries. Ironically my wife last night announced that the battery in her iPhone 5S was not holding a charge like it formerly did. Anyone with this problem also knows that mobile phone stores do not generally even carry replacement batteries. These retailers prefer to use the situation to try to sell you a new phone.
