Everyone has been waiting hear just how long Apple's smartwatch will last on a charge. Well, we'll have to wait for confirmation, but current rumors don't suggest there's any reason to believe that Cupertino has solved the biggest problem plaguing the market. According to 9to5Mac the Apple Watch will settle in at about two to three days in standby mode, and between 2.5 and 3.5 hours of active application use. In other words: not much better than existing smartwatches. Just displaying the watch face is enough to drain the battery in three hours, though, we imagine nobody is going to keep the time displayed for three hours straight. Apple's goal is apparently 19 hours of mixed use, but reports are that it will probably fall short of that benchmark with its first generation device.
