The iWatch is going to be announced tomorrow. The device is expected to be a complete health tracking solution. The latest leak seems to confirm that the iWatch will be available in 2 sizes. It will have a microphone, speaker, Siri, flexible touchscreen, 1+ day battery life, wireless charging, and a sensor plate. It will be available in 4 color combinations and waterproof to 20m.
You can keep up with this leak on Reddit. I really hoped these watch makers could come up with a device that would last more than a day on a full battery charge. If this leak is legitimate, then we will probably have to wait for a while before a smartwatch with a decent battery life hits the market.
