Italy’s Competition Authority has fined both Apple and Samsung the maximum amounts possible for deliberately slowing the performance of their phones with the apparent intent of motivating the owners to replace them with newer, pricier phones. 
Both firms provided updates to phones that caused malfunctions and lowered the speed. Neither firm provided any means by which the phones could be restored to their previous capabilities. 
Planned Obsolescence is where you deliberately design a product to only last a limited amount of time. Common with automobiles and similar products, it has been far less practiced in consumer electronics since the products’ capabilities have developed so quickly. 
However, when money is involved, what is unnecessary may still be profitable. They took their own products and handicapped their capabilities so they would reap greater profits when they were replaced. 
Simply put, this is not good business ethics. It is the direct opposite – manipulating customers to buy under the pretence that their phones were too slow – when the update provided by the manufacturer created the problem in the first place. This is stealing and certainly causes one to have serious doubts about the trustworthiness of the companies involved.
