The watch will be packed with efficient battery backup which will last the whole day, and will not take as long as it takes to charge an iPhone, Cook said.
The company is planning to unveil the Apple watch at a special event scheduled for tomorrow, March 9, 2015 and it will be available for costumers after April.
There will be lots of other potentially revolutionary uses. The watch is designed to be able to replace car keys and the clumsy, large fobs that are now used by many vehicles, Cook told the newspaper in an interview. This could be a major development and will reinforce the view that Apple is circling the automotive market.
The smartwatch will be tethered to iPhones through Bluetooth, automakers that already have an app of their own and which efficiently handles tasks like locking and unlocking doors, manages climate, and flashing the lights will be more near to a companion app that will support the functioning of the Watch.
