Laptop battery life is intensified in Intel and ARM race



The battery life of a laptop is one of the more contentious specifications from the manufacturer cited. There can often be a big gap between manufacturer requirements and typical real-life use – but there's something Intel hopes to change …

Apple makes the following battery life requirements for its current Mac laptops: [19659004] MacBook Air: Up to 12 hours of web playback / 13 hours of movie

  • MacBook Pro: Up to 10 hours of web / movie playback
  • Using these machines, as well as Windows equivalents, is really close to half of them the numbers . This is in contrast to Apple's iPad battery life requirements, which are usually very accurate.

    The Verge reports on a new Intel initiative designed to ensure that laptops that promise long battery life deliver a reality minimum of nine hours.

    Starting today, you'll start to see a label that says "Engineered for mobile performance" next to laptops that last nine hours on charge, go from sleep to surf the web in under two seconds, and perform just as quickly when it is disconnected.

    Intel says that the laptops that receive the label will need to pass a verification process with Intel's engineers, and it has more than 100 partners on board.

    Intel does not do this to be friendly to consumers: there is concern about a new influx of ARM-powered laptops that offer far better battery life than those with Intel CPUs. It is hoped that buyers will realize that nine hours of real life use is good enough.

    However, the recently announced Samsung Galaxy Book S gives an indication of the challenge Intel faces from ARM in terms of laptop battery life. The new machine requires 23 hours of service life, and although the usual formula applies (divide the manufacturer's requirements by two), it will still equal nearly 12 hours of actual service life.

    It has long been clear that Apple is on the road that at some point will see it ditch Intel chips in favor of its own ARM-based, in exactly the same way that Apple-designed A-series chips drive iPhones and iPads. This is a view we have expressed in 2016, 2017 and 2018.

    By designing custom pieces for iOS devices, Apple gets two core benefits.

    First, efficiency. By designing both hardware and software in tandem, Apple can get much more out of its components than competing manufacturers. It is often noted that Apple puts less RAM into iPhones and iPads than rivals do on Android phones and tablets, and yet the benchmark portfolio shows that Apple typically performs at least as good as its flagship devices, and often significantly better.

    Second, freedom from restrictions imposed by third-party chip companies. Most Android brands are limited by what Qualcomm chooses to offer using smartphone CPUs and when it chooses to launch them. Apple, on the other hand, can do its own thing.

    The same benefits would apply equally well to Macs if Apple designed their own portable chips.

    In particular, Apple will be able to make its Mac update cycle decisions without being hampered by Intel's CPU routing tables.

    There are three challenges for Apple, all of which seem soluble. But one thing that will not be a challenge is the battery life. In fact, with Apple-designed ARM-powered Mac processors, we can see the famous accuracy of the iPad battery's lifetime requirements mirrored by those for MacBooks.
