The issue of battery drain still haunts many users, so that we have to dispense with some features in favor of the battery, and Apple has made a great effort in managing battery power, such as an improved low power mode, a dark mode, and a battery health section and detecting which applications are draining their energy , And you may have noticed that while using some applications, the battery is drained quickly, especially the Facebook and Messenger applications, and this is what was mentioned by a former data employee in the company Meta or Facebook previously, that the company may deliberately drain the batteries of the iPhone and Android secretly as part of its internal tests.
In an interview with the New York Post, George Hayward claimed he was fired last November for refusing to participate in what is known as “negative testing” while working on the Messenger app.
A negative test is a way to test an application and see if it can properly handle wrong data being entered in places it is not intended to. For example, if the user tries to type a character in a field that requires numeric input, the message “Invalid data type, please enter a number” message will be displayed.
According to George Hayward, the "negative testing" technique enables Internet companies to "surreptitiously" drain a phone's battery in the name of testing features or dealing with problems, such as how fast an app launches or how an image loads, and so on. He stated that he had filed a lawsuit in the Manhattan Federal Court regarding this matter against Mita, but he later withdrew the lawsuit due to the arbitration clause. ”
As mentioned site QA SourceNegative testing allows developers to compare expected output with incorrect output by revealing how the application responds to invalid data.
Hayward also says that this practice "could harm someone" by draining the battery without warning. He did not say how many people were affected by this negative test.
He stated that he was given an internal training document titled, “How to Conduct Informed Negative Tests,” which included examples of battery drain experiments being conducted, and then claimed he was fired after three years working with the company for refusing to participate in these tests.
Facebook apps have long been accused of causing iPhone battery drain, to the point that in 2020, it was reported on the popular Reddit site, that the Facebook Messenger app has outperformed the PUBG game in incredibly draining battery.
