Kind of related, but Samsung has ads in the US for the Galaxy S9 mocking the iPhone 6 for its battery problems. All I can say is that it's highly deceptive.
It starts off with the protagonist with her iPhone 6 where it can't bring up her mobile boarding passes while she's at an airport. It shows a completely white screen other than the time and wireless bars, which I have never, ever seen before until it finally comes up and the agent yells at her for holding up the line. Then at an Apple Store she talks to an employee who looks like a real slob and whose only answers are that she can either upgrade or turn of "performance management". Then outside she sees a father and son both with hair resembling the notch on an iPhone X. Not sure what that has to do anything other than a cheap shot at Apple's industrial design.
That's just horrendously deceptive, because the first thing an Apple employee would suggest is taking advantage of their $29 battery replacement promotion.
The comments attached to this video on YouTube include a lot of people pointing out stuff such as the battery change taking care of the issue, along with it being a really bad comparison of a 4 year old device to one from Samsung that's only been out a few months. I'm somewhat surprise that Samsung USA didn't have those comments censored.
