it was during the iPhone 6s series that made the iPhone the king of smartphones
it was during the iPhone 6s series that introduced:
1. bigger screens (it was the 6 but the 6s were more reliable in durability)
2. better (longlasting for the 6s plus, also same with the 6 series, 6s were more reliable) battery life
3. double sized ram
4. more than twice megapixel size jump
5. first 64 bit chip iphone
6. 3d touch
this fone not only repaired the problems of the past iPhones, but it was revolutionary for a phone to pack all those features or upgrades in a single release.
in fact the iPhone 6s series together is the oldest fone you can recommend someone to use and is still snappy and fluid
after the 6s, understandable since that fone is iPhones biggest upgrade in terms of reliability and performance, had kind of went downhill. The rehash design from 7 to 8, removal of headphone jack, and that almost $1000 iPhone X, slowed the upward climb. Competition got stronger, the lack of big upgrades while keeping the price much more expensive turned off customer.
But, the XR, was a huge hit, offering flagship and solid features with a lower price.
The iPhone 11 even got a lesser price than the least expensive iPhone XR, and now not even them were expecting that the base iPhone 11 is selling faster than they forecasted to be
is iPhone 11 the most important and biggest upgrade in iPhone launch history ever?
