Both Foxconn and TSMC requires capacity planing and lead time especially for Xmas production. It is the 2019 1H estimate that is concern when both of them has lowered forecast. Right now 10-20% drop is an industry wide format number.
[doublepost=1544591779][/doublepost]Where did that 20M iPhone XS Max number came from?
Deriving from Mixpanel Data, the iPhone Xs / Max are actually selling better than expected, even topping last year iPhone X in unit, expecting a total of 50M by the end of December. iPhone 8 with 10M, iPhone XR with 25M. 5M others.
The 20million number comes from the Mixpanel data for Xs Max. The article states that the Max represents 2.81% of the installed user base. I think trombone used 715,000,000 as the estimated user base (I've seen that number from an analytical firm back in early 2017). 2.81% of 715million is roughly 20million Max units.
Assuming a 10% off in base number that is roughly 81M Unit to 90M unit. So in terms of unit sales, they might actually beat least years figure or even a new record. ( Apple wont release number but they will likely say it is a new record )
The iPhone XS is clearly an unexpected success, I assume most in the industry were wrong in how iPhone X remain the most popular smartphone through out the year, many expect it in the first launch quarter, but not the next three. It seems we have the same pattern here. Many thought those who got X wont be upgrading to Xs and hence may be a smaller number of sales. Which turns out to be wrong too.
The outliner are iPhone 8, which increase 1% and I assume it is due to the lack of / upgrading from iPhone SE. And iPhone XR, which previously were projected up 100 to 120M unit through 2019, and should expect ~40M unit this quarter. So iPhone XR is indeed running short of expectation.
Tl;dr : iPhone Sales as a whole are doing fine. iPhone XR may be not.
I use the Mixpanel data differently and come up with the following.
I'm using 675,000,000 as the estimated installed user base. Source -
https://www.businessinsider.com/apple-installed-base-iphone-8-stopped-growing-2017-7
Xs - 2.26% of installed base
Max - 2.81%
Xr - 1.66%
This would imply unit sales of ...
Xs - 15 million
Max - 19 million
Xr - 11 million
Total - 45 million, through Dec 10th.
There's approximately 90 days in a quarter. Dec 10th is approximately day 70. So I factor in 1.28 for the days remaining in the year. The totals are now.
Xs - 19 million
Max - 24 million
Xr - 14 million
Total - 57 million
Here's where we get dicey. What percentage of new phones sold are the older ones?
I can use 80-20 or 70-30.
80-20 mix - 71.2 million iPhones
70-30 mix - 81.4 million iPhones
The last 2 Christmas quarters, Apple sold around 79 million both times. At an 80-20 mix, Apple disappoints dramatically. At the 70-30 mix, it's an all-time record.
Here's where more insight/data is required. Knowing the new sales of the older models would be very helpful in determining the "mix". The methodology I used locks in the unit sales of the new models, so the lower the mix, the more total unit sales.
Anyway, this is what I could put together in ten minutes. If I had more time, I could do a little more googling to see if there are indicators of 7/8 sales.
EDIT - usually around this time of year, CIRP releases a chart showing the breakdown of new iPhone sales by model (for US). Typically for the Dec quarter, the breakdown of the new models vs. the old models is between 60/40 to 70/30. I think the last time the mix was in the 80/20 range was in 2014 with the 6/6+.
Opinion - I think Apple will be fine with unit sales.
