(In my opinion and expectations for wearing something on my wrist) The Apple Watch is the best watch money can buy...... except when the battery goes flat. I like everything about my apple watch, actually in contrast to the iPhone it has good battery life as well. But in contrast to other watches, it's got exceptionally terrible battery life. I find it hard to believe apple were not able to design and build a better power source than a lithium-ion battery. Clearly some sort of kinetic energy recharge, perhaps mixed with a solar cell built into the screen, is going to be the killer feature of the apple watch "2"? Thoughts? Opinions? Any information about apple patents and buyouts that could provide a hint?
