TrendForce, which bills themselves an international analyst firm that’s based in Taiwan, recently surveyed 3,000 people about Samsung’s upcoming Galaxy S4. They made a lot of claims using their data, but the most shocking one is that 52.4% of iPhone users in China want to dump their phone and replace it with a GS4.

That sure sounds compelling, but let’s take a deeper look.

First obvious question: Is a sample size of 3,000 adequate? Normally I’d say anything above 1,000 is golden, but the population of China is over 1.3 billion. That means the sample size queried in this study reflects just 0.0002% of the thoughts and feelings of a nation.

But let’s forget about that and just focus on the people rich enough to buy an iPhone. How many iPhones are currently being used in China? That’s an incredibly tough question to answer, so let’s focus on 2012 data. Strategy Analytics says Samsung, with their 30.06 million smartphone sales in China in 2012, earned 17.7% of the market. That means the total size of the market last year was 169.83 million. The firm also says Apple had 11% of that, which translates to 18.7 million.

Now assuming half the people rich enough to buy an iPhone last year have enough money to buy a Galaxy S4 this year, that’s 9.35 million units. Hardly a figure to sneeze at, but it’s still a fraction of the number of GS4 units that Samsung plans to ship during the lifetime of the device.
