Tesla CEO Elon Musk let rip at Apple during an earnings call over the tech giant's use of cobalt in its batteries, and fixation with controlling software used on its devices.
Musk, 50, went after Apple for its use of cobalt in its iPhone and Mac batteries and the famously-control it exerts over software used on its popular devices.
When asked about raw materials used in its car batteries, Musk said the company uses significantly less cobalt than Apple, whose headquarters is in Cupertino, California.

Musk said Tesla uses 2% cobalt while Apple uses 100% in its batteries
'And there's somehow a misconception that Tesla uses a lot of cobalt, but we actually don't,' Musk said, according to a transcript of the call. 'Apple uses I think almost 100 percent cobalt in their batteries in cellphones and laptops.'
'But Tesla uses no cobalt in our iron phosphate packs, and almost none in the nickel-based chemistries,' Musk added.
'On a weighted average basis, we might use two percent cobalt compared to say Apple's 100 percent cobalt. Anyway, it's really just not a pack that we expect to basically have zero cobalt in the future.'
This is not the first time Musk has taken shots at Apple, despite revealing in 2020 that he approached the company and CEO Tim Cook about an acquisition, but Cook did not take his call.
In 2018, he said Apple was not as innovative as it used to be and three years prior, he called Apple a 'Tesla graveyard' for ex-Tesla employees.
The two tech giants do not directly compete with one another at the minute, although Apple is reportedly working on an electric vehicle under Project Titan, which is led by ex-Tesla employee Doug Field.
At the company's Battery Day Event in September 2020, Tesla said it would eventually make its batteries with cobalt-free cathodes due to the way it is mined and the havoc it wreaks on the environment.
Cobalt has been referred to as the 'blood diamond of batteries,' according to The Verge.
Both companies, along with several other tech giants, were named in a 2019 lawsuit by an international humans right group over how cobalt is mined by young children.
In Apple's 2021 environmental progress report, the tech giant said 100 percent of its smelters and refiners of cobalt (along with other metals) participated in an independent third-party audit.
The company added that it is 'prioritizing' 14 materials, including cobalt, in the hopes of upping the amount of recycled material used, or replacing them altogether.
'We’ve worked to increase our recycled cobalt year after year— doubling the amount of recycled material used in fiscal year 2020 from the previous year,' Apple wrote in the report.
'And the cobalt from iPhone batteries disassembled by its recycling robot Daisy is being returned to the general market. This more efficient and economical approach makes
