The phone being unreliable and constantly shutting down would arguably be a way more effective method of “planned obsolescence”.

My 2015 MacBook Pro has the issue of shutting down or turning off when still at 20% or 30% battery and I find it immensely frustrating (I assume it’s a similar issue of an old battery not being consistent). I’d much rather it be throttled and be reliable.

They found a way to cover up an ongoing design flaw in the phone/battery capacity combination. The phones are too powerful for the batteries that Apple uses.

Almost no other line of phones has this issue.

It is amazing how people twist this situation to make Apple the hero for saving "old" phones.

That's FUD.

The phones absolutely did not behave like that when new. And, if the battery is replaced, they go back to their original performance.

You are FUD. You obviously dont own an iphone 6/6s and havent been impacted by ios updates
