How many iPhones were sold in India in 2022?

Clarifying Questions -
1.) New iphones or used iphones ? New iphones sold from retail and online combined
2.) Are we looking for the latest model no. or all models? All models combined.

Approach :
1. I would want to look at eligible population for smartphones?
2. How many can purchase a premium (50K INR +) phone?
3. How many purchase Iphone?
4. Avg years a iphone is used?
5. Quick sanity check

Solution ->

Total population of India -> 1.4 B

Out of which,
Below 15 years - 25%
Above 65 years -> 7 %
Children below 15 years usually will not have a phone or if they have a phone it will be a used phone.
Above 65 years people generally in india finds difficulty using the smartphone and would prefer a normal feature phone
so therefore I will not be considering both of these population group
Total eligible population group -> 68 % , It can be estimated to 70%
Eligible population -> 980M (70% of 1.4 B)

Out of the 980M,
10% will be from lower middle class and below income level (10-12k per month )
90 % will be from middle class, Upper middle class and Elite class
Total population eligible to buy premium phone - 882 M (90% of 980 M)

Now android: iphone phones in india is around 95:5
So no of iphones = 5% of 882M => 44.1 M

Iphones holding period is around 2-3 years. Let's take 2.5 years as an average.
Total iphone sold in the year = 44.1 /2.5 => 17.64 M

Quick Sanity check :
17.64M is around 1.3 % of total india population which seems fair.
