Apple have sold roughly 400,000,000 iphones since the release of the 6.
100 faults is hardly significant.
The USA has around 10,000 murders a year with a population roughly that of 1 years sales of iphones.
A faulty phone is the least of your worries.
In the last 6 years I have had 3 iPhones and they all still work.
In the same timeframe, 4 credit cards have failed me at the checkout.
If only I had bought Apple shares...they actually a product.
