If you are conducting a survey among iPhone 17 Pro Max owners asking, “What’s ONE feature you’ve discovered that actually made you say, ‘This is why I upgraded’?” and “If you could change ONE thing about the 17 Pro Max, what would it be?”, the purpose of the survey is not very clear from the post.
Are you trying to identify genuine advantages of the iPhone 17 Pro Max over previous iPhone models, understand issues or shortcomings that users have encountered, or simply collect general user experiences and opinions?
If the intention is to highlight a particular issue, compare the 17 Pro Max with another iPhone, or draw some meaningful conclusion from the responses, that objective should be clearly stated.
Otherwise, the questions may generate a collection of interesting opinions, but it will be difficult for readers to understand what the survey is ultimately trying to establish or how the responses will be used.
If this is intended for academic or analytical research, the methodology and purpose should be even clearer. A good survey should tell participants why their responses are being collected and what question the survey is actually trying to answer.
