This is false, it was to avoid situations where the battery couldn’t provide enough current and would likely cut out causing the phone to switch off. It seems the intentions were reasonable to keep older phones usable for longer and they fairly quickly rolled out a large discount on the cost of battery replacement when the public outrage started.
Which one are you more likely to replace sooner?
I would assume that like most Android phones and (2000s) windows laptops the phone is just old because of age and I need to buy a new one to get faster one.
> And you got phone which just switches off randomly.
I would assume that something is wrong with the phone and would get it looked into at-least once to know what the issue is. Apple would (presumably[1]) tell me its just the battery which needs to change nothing else and I would do just that.
[1] I have read articles where it is mentioned that even geniuses were unaware of the throttling feature.
