Apple Trying to Beef Up Battery Engineering Team

In the wake of ongoing complaints about battery performance and reporting on MacBook Pro with Touch Bar, Apple is looking to beef up its battery-engineering team. 9to5Mac noted the company just added two positions related to batteries, Battery Algorithm Analysis Engineer and System Power and Control Architect.

The positions were added to Apple’s job site on December 14th and 15th, respectively, making it appear to be a reaction to MacBook Pro battery issues. Users have been complaining of erratic battery performance, as well as battery performance that didn’t match reported battery life.

Apple’s solution to the former was to simply remove reported battery life from macOS Sierra. The addition of these new job postings suggests Apple may be interested in solving the problem long term, rather than hiding the erroneous data.

Battery Algorithm Analysis Engineer Job Description

In this position, you will be expected to verify advanced lithium-ion battery management technology through battery testing and data analysis. You will also be asked to create test plans and conducting battery tests. You will be expected to process test data to generate steady-state and dynamical models, identify model parameters, and implement various model-based algorithms in different test platforms to evaluate their performance.

System Power and Control Architect Job Description

Apple’s Platform Architecture team is looking for a resourceful systems architect to develop, prototype and analyze efficacy and robustness of power control algorithms. The ideal candidate is a self-motivated individual that creatively explores solutions and uses thoughtful data driven analysis to evaluate prototype implementations. The architect will be part of a product-focused cross-functional silicon, software and system development team.

9to5Mac also noted that Apple has had a third position posted since November 28th, that of Sr. Battery Test / Process Engineer.

Sr. Battery Test / Process Engineer Job Description

In this crucial role, you will be part of a budding electrical test lab focused on internal testing of batteries. You will be directly working with the testing team, warehouse team equipment and software teams along with internal customers to optimize all aspects of the lab operations to improve its efficiency, quality and output.

Note the mention of a “budding electrical test lab” inside Apple. It’s a tad surprising that such a lab is only budding, but one way or another it shows Apple is getting ever more serious about battery performance.

This issue that has plagued MacBook Pro users is really more of an intensifying of a long-standing issue with electronic devices. The reality is that predicting battery life is part voodoo. And Apple, a company that works hard to eke out every tiny bit of battery life it can get in its relentless pursuit of thin has plenty of reasons to want to be better at this particular thing.

Let’s hope that’s what these new job postings are about, and that the eventual hires can help.

  1. “It’s a tad surprising that such a lab is only budding”

    Why? I’m sure most of this is currently done at the suppliers who actually make the batteries for Apple. One might draw the conclusion that Apple is bringing this “home” because they may eventually plan to start manufacturing their batteries themselves.

    “The reality is that predicting battery life is part voodoo”

    It actually isn’t. It just can’t accurately predict how much is left without learning user habits. That takes time. I believe Apple said it would take about a month for the system to start accurately predicting how much battery life is left based on previous usage. That data is crucial.

  2. “One might draw the conclusion that Apple is bringing this “home” because they may eventually plan to start manufacturing their batteries themselves.”

    This week Apple attended a meeting with President Elect Trump who wants to bring manufacturing back to the United States. Yes, that is easier said than done and this battery announcement may just be a coincidence.

  3. What people don’t seem to realize is that the 2016 MacBook Pros have batteries which are 30% SMALLER than the batteries of the 2015 MacBook Pros.

    Apple thought it could get away with it. But the new Intel Processors and GPU use the same energy as the 2015 models. So the smaller batteries in the name of thinner computers is kicking Apple in the shins.

    Shame on Apple for making the batteries much smaller and less useful in the newer models.
