Only partially. Analysts think China is responsible for about 2 million units. However, this year for the launch weekend, Apple sold around 3 million more (total 13 million) than last year (10 million), which means probably 1 million more excluding China, or about a 10% increase excluding China.
It's always hard to get much meaning out of launch numbers for Apple b/c there's no way to know how much they were supply constrained, especially in China.
Like to like, 10% increase is on the low end IMO - I honestly was expecting closer to 20-25% y/o/y growth, normalized for additional markets. However this could just be supply.
I fully expect full on quarter growth, normalized for days, to be closer to 20%.
