IPHONE INSIDE BATTERY
A tour of Apple’s iPhone 6 battery helps nail down the one variable that determines manufacturing cost.
Li-polymer batteries are ubiquitous. They are everywhere: cellphones, tablets, laptops and hybrid or electric cars. We rarely think about them except when the discussion turns to the rather short battery life seen in some consumer electronics. Smartwatches, like some laptops, come to mind where battery life is measured at less than a day. This has me thinking about batteries, and are there commonalities between the batteries seen in smartwatches, cellphones and tablets.
