I think posts like this don't actually portray the reality of the situation.
iPhones in general last longer than any other phones Android or otherwise. This isn't under contention as there are numerous independent studies that prove this. However, this durability raises an important problem for Apple though.
So I have an iPhone 6+ and it was affected by this issue. When reading up WHY Apple did this it makes sense to me. If my battery is in a degraded position then any app that isn't efficient could tip the phone to the point where there's not enough charge to keep the phone running. It won't take much to do and from my perspective all I'll see is the battery going from 90% to phone switched off just like that.
To someone who doesn't know what's causing this they are going to blame Apple not the battery. So Apple made the decision to slow the phone down. The problem is they forgot to tell people they were doing it and so people railed on Apple involving them in some sort of planned obsolescence conspiracy theory (such as this author). This wasn't the case it was always to ensure the phone carried on running.
When Apple explained what was going on most iPhone users understood and carried on in the knowledge they are going to get longer use of their phones. However, the Apple haters and people who are paid shills of Samsung, Google, and Microsoft carried on this conspiracy to try and ruin Apple's reputation and make more money. The anti-Apple brigade jumped on the bandwagon.
Meanwhile Android phones just die completely and no one cares because it's expected of them.
Now every iPhone has this information in the phone, that information is transparent, and users just carry on using their phone as normal. Meanwhile Google introduced something similar to Android and no one batted an eyelid which leads me to believe that this issue is simply because there are so many Apple haters out there wanting to see Apple fail. That is discrimination and illegal in most countries.
