Apple previously said that the upcoming Apple Watch would require a daily recharge. However, the company has not revealed any details on the wearable's battery life.
Now, several reports are saying how the Apple Watch battery performs when the wearable is used heavily and also when it is worn with mixed usage.
There's also a mention on how much battery life is consumed when one is playing games, using standards apps and enabling the fitness tracking mode.
Apple initially designed the Apple Watch battery to be capable of lasting one full day with some amount of usage brought by active use and a large amount to be credited to passive use. To be exact, Apple wanted the Watch to deliver around 2.5 to 4 hours of active use and 19 hours of combined usage of active and passive.
Pure standby time would stretch the battery life up to three days; leaving the watch in sleep mode would stretch the battery life a bit further to reach four days. However, it is speculated that Apple would most likely achieve around two to three days of battery life in either standby mode or with low power usage.
For those who are looking into the wearable's fitness tracking feature and plan to use it heavily, they are in for some better news.
"Apple expects to see better battery life when using the Watch's fitness tracking software, which is targeted for nearly four hours of straight exercise tracking on a single charge," said Apple.
Rumors about the watch's battery life have been circulating since September when the wearable was first announced. Even Tim Cook said users would have to charge the Watch daily.
According to several reports, the Apple Watch runs on a "stripped down" version of iOS known only by the codename SkiHill. The wearable is also said to have Apple's S1 chip, which is close to what one can find inside the current-generation iPod Touch.
The real challenge to the battery life's performance is the watch's relatively powerful processor and the high-quality Retina-class color display, which contribute to the battery's power drain.
Several sources are saying that Apple has been deeply concerned about the Watch's battery life for the past year. The situation must have been the reason why Apple had to push back its launch from late 2014 to early 2015.
In order to determine the Watch's performance in the real world and under a number of conditions, Apple has released almost 3,000 test units to be in circulation. Most of these watches reportedly belong to the stainless steel models.
