Apple Watch battery expectations and powerful CPU revealed in new report

Battery life for some of the more popular wearables out in the market has always been a major topic of discussion, and it only picked up steam when Apple officially unveiled the Watch.

While Apple has been relatively coy regarding the battery life for its first wearable, it is known that the device will have “about a day’s” worth of life, and that Apple fully expects owners to charge the wearable once a day. While that has led many to wonder why the Watch is priced so high for a battery life that’s quite low (even compared to some of the competition, which is cheaper right out of the gate). The trade-offs that Apple made may explain the reasoning behind it.

According to a report published by 9to5Mac, and citing sources familiar with the matter, Apple’s expectations for the Watch’s battery life, and the details connected to it, have been revealed. While nothing is official quite yet, the report states that Apple opted to use a powerful processor under the hood of the Watch, and a display that’s being descried as “high quality.” Both of these features alone can contribute to the drain of a battery, but put them together then the “about a day” battery life starts to make sense.

Moreover, the report indicates that the processor within the Watch, which is powering a stripped down version of iOS reportedly called SkiHill, the S1 chipset is said to be on the level with the A5 processor that’s found within the iPod touch. The display is apparently “Retina class” when it comes to color, and it will reportedly be able to run at 60 frames per second.

As far as the expectations go, Apple has been doing testing across the board with the wearable, including with first- and third-party apps. All of that equals to Apple aiming for between 2 and a half hours to four hours worth of active application use on the device. Apple was aiming for 19 hours of combined active/passive use with the device, while they were also going for around three days of standby time. If left in sleeping mode, Apple’s goals for the Watch were four days.

The sources believe that Apple will only achieve about two to three days of standby time while the device is in sleeping mode.

Testing with apps has shown that Apple is going for 2.5 hours of “heavy app usage,” like playing a lot of games, before the battery would need to be charged after being topped up. With just “standard app usage,” Apple is apparently aiming for three and a half hours of battery life. For the fitness tracking part of the Watch, Apple is aiming to get four hours of straight usage, which is arguably quite good considering the other numbers.

The report goes on to note that Apple has been furiously testing the Watch out in the real world, mainly the Stainless Steel variant, with up to 3,000 units floating around at Apple HQ. This is all a means to an end, as Apple strives to tweak the battery and extend its life as much as it can. It goes on to say that Apple’s woes with the battery are the reason why the Watch was delayed from a late 2014 launch to an early 2015 one.

Are you worried about the Watch’s battery life?
