Rumour Says iWatch To Incorporate 100mah Battery13 December 2013bzamayo.com/iwatch-battery-rumourGForGames: Now, according to this source, Apple has already tested two iWatch prototypes, and the company has supposedly decided that the accessory will go on sale in October 2014 (most likely alongside the upcoming iPhone). More so, the source also suggests that Apple still hasn’t decided on how big/small a screen they should fit on the final product. However, it appears that the testing units are being powered by a 100 mA battery, which is rather underwhelming considering the fact that the Galaxy Gear has a 315 mA battery. Some watch batteries are rated higher than 100 mah. This has to be incorrect (or frankly, made up) information.
