Apple told the Guardian: “A small portion of Siri requests are analysed to improve Siri and dictation. User requests are not associated with the user’s Apple ID. Siri responses are analysed in secure facilities and all reviewers are under the obligation to adhere to Apple’s strict confidentiality requirements.” The company added that a very small random subset, less than 1% of daily Siri activations, are used for grading, and those used are typically only a few seconds long.
> Apple didn't want your phone to shut off at 15% when the battery can't supply enough current to sustain full performance.That's what they told you to believe. Every other manufacturer also had smartphones with batteries at the time and they were not doing this FYI. That was just marketing speak by Apple. Please stop citing marketing speak.
This is not the core issue, though. The core issue is not disclosing financial incentives while commenting something positive / negative.
