Updated 12/29/17: Apple has posted an official response to this issue on their website. It’s the right response.
Everyone’s chiming in on this issue so I’m not going to rehash it, but I do have a practical suggestion that addresses it. You know what’s going on: older iPhones with older batteries tend to run slow (see this post). I noticed it as well and thought, like most people, that we (my wife and I) need to replace our iPhones, because they’re getting too old to handle the iOS upgrades and respective upgrades to the mobile apps we use.
As it turns out, Apple has been quietly throttling the CPU speeds of our iPhones in order to compensate for the fact that older Li-Ion batteries can’t sustain the voltages needed for those higher speeds. It was watching out for us, but without explaining it. And as it turns out in life, a lack of communication will cause problems. They only offered the explanation after people got upset — so upset that now several lawsuits have been filed against them (see this post). Only two lawsuits are mentioned in that post, but in another story I read today, the total went up to eight.
I’m not feeling sorry for Apple. They’re big boys, they have plenty of money to handle the lawsuits and their “we know better” attitude toward the customers, as well as their closed system approach to everything they develop, has always engendered a certain amount of anger from its customers. What they can and should do now is to suck it up and offer a good defense in court.
All of this could have been avoided if they’d simply done something similar to the “Low Power Mode” option that’s already offered on iPhones. That is an elegant and caring solution to a problem that users encounter every day.
Something like this, let’s call it a “Battery Lifespan Advisory”, could be a feature launched with the next incremental upgrade to iOS 11, and it might let us toggle the “Automatic CPU Throttling” on or off when the battery nears the end of its projected lifespan. We could get a message on our screens, just like when Low Battery Mode is recommended, that would take us directly to the screen where we read an explanation and get to manage this option.
And that’s about all I have to say on this.
