Now in these days Samsung has presented their new coming smartwatch for connecting to their Android smartphones, it is indeed a very impressive Watch, but terrible battery time, you would have to recharge it everyday.
I am not one of these who wish to recharge a watch every single day, a watch shall be easy to use and longer battery time. Like the new AGENT smartwatch with between 7 and 30 days of battery time and wireless charging station. Full support for both Android and Windows Phone 8. The watch is developed with .NET development framework.
