THE PROBLEM WITH SMART WATCHES
The idea of a smart watch is exciting and alluring, but most smart watches today are nothing more than just a secondary display for your smartphone or tablet. If it is an important call, message or email, you would still need to get to your phone. Furthermore, most smart watches typically using Bluetooth to establish a connection to your smartphone and this means you have to stay within range for it to work.
And then there is the problem with batteries. Batteries in smart watches typically only last a couple of days, but the problem is not with the smart watch, it is the phone. Most smartphones today have just about enough juice to last a day, but leaving Bluetooth activated the entire time has a negative impact on battery life. This means most users would not be able to get through an entire day without a midday charge or external battery pack.
