Android flagships could soon pack massive 10,000mAh batteries, thanks to iPhone's battery tech

10,000mAh in a smartphone is double the current norm. Android flagships could get such batteries within the next few years thanks to Apple's technology. It's a rigid steel casing and a stacked-cell design that allows capacity to increase without growing thickness. Samsung and other major vendors are already testing this combination. For the user, that means two to three days of use without an outlet. But price and weight will go up. If it all works out, daily charging will no longer be necessary.
