One of the biggest challenges is lack of standardization.
Vendors have cleared a number of technical hurdles but still must address some more obstacles before any of the new battery options become available.
Major vendors are using different types and amounts of fuel to power batteries of different sizes, so it will not be easy for them to deliver the volumes and scale necessary to drive down pricing.
Power management has been an area of focus, and handset vendors are delivering systems that closely monitor power usage and deliver only the amount of power needed.
Between two evils, choose neither; between two goods, choose both
Every time you perform you learn a little bit more.
