This is before anyone has had a chance to use an Apple Watch or more than a few minutes, but Jess Bolluyt thinks battery life is the devices Achilles heel.
It seems increasingly likely that Apple has chosen to compromise battery life to build a smartwatch packed with features and functionality
I remember reading about experts who said it was not possible for an iPad have a 10-hour battery life.
[Experts] think that the Apple Watch is likely to include software that regulates the device’s activity in order to conserve the battery, and that could mean that users won’t be able to use all of the device’s functionality at once, or leave the display on. So while all of Apple Watch’s functions — its ability to send and receive messages, answer phone calls, read emails, or use the walkie-talkie or heartbeat functions — will appeal to consumers considering a purchase of Apple’s first smartwatch, it’s likely that the device’s battery won’t be robust enough to enable them to use each of those functions as frequently as they imagine. Apple has conspicuously avoided giving a definitive number of days (or hours) that the battery will last, or addressing how the device will handle the demands of the operating system and its various functions and apps.
