The Apple iWatch isn't going to be released until this Fall, and this is why.

According to Chinese news source Economic Daily News, the release of the iPhone 6 with the iWatch is expected to take place this Fall, primarily due to Apple’s focus on battery power.

Xiao Junhui reports on UDN.com that in order for Apple to release the iWatch, the device must reach zero power consumption when in stand-by, while retaining the ability to wake instantly.

To further solidify this rumor, besides common sense, is the integration of wireless charging technology, as reported by xueqiu.com. The technology is currently absent from any other competing smartwatch manufacturer, from the low end to the high end of the spectrum.

The iWatch is expected to use an organic light-emitting diode (OLED) screen, among the power-saving features. The display for the iPhone 6 will most likely be manufactured by LG (LG Display) and JDI (Japan Display Corporation), but it is still unclear whether the same two companies will contribute to the iWatch display.

With an estimated price tag of $349, Apple’s two supply chains, Quanta and Inventec, are rumored to begin with an estimated shipment up to $10 million for starters, to be increased into next year as demand matches production. Quanta will perform most of the assembly in respect to Inventec. TPK might also be involved into the manufacturing of nano-silver technology, to be integrated into the iWatch supply chain.

If successful, Apple will deliver the smart watch, with ultimate power efficiency, benefiting users of the device with up to 5 days of usage on a single charge.
