I feel like more transparency would have been welcomed, but aside from that this is a "no win" situation, since you have to pick a winner: - Do you degrade performance but leave screen-on time relatively unchanged? - Do you degrade screen-on time but leave performance relatively unchanged? Most Android devices seem to do the opposite (lose screen-on time, but keep performance relatively unchanged). Different people w…

I think out of the two options, Apple picked the far more deceptive one, or at least the one that will be perceived to be deceptive (which IMO is the same thing). Few people would be surprised that batteries degrade over time, eventually causing noticeable drops in battery life, many people seem surprised that performance is intentionally and artificially reduced over time.

I completely disagree. Apple chose to have the phone continue to work all day. That will keep it useful more than being fast.

A better option is a larger battery, but without that, I think they make more customers happy than I'd they did the alternative.

> Under iOS 11.2.0 the effect is even more pronounced.

No, the effect is exactly the same as you can see from the charts since they peak at the same benchmark scores. It is the distribution of those effects that is different, with the performance being negatively affected for more phones. But keep in mind that under iOS 11.2.0, most iPhone 6S's that are tested are probably about 2 years old. Under iOS 10.x, most iPhone 6S's probably about 1 year old. I'd like to know the distribution of the times that these Geekbench benchmarks were run. If scores for one phone model in one month are one average score under iOS (x) but is substantially lower the next month under iOS (x+1), then I would consider that to be a significant act of "planned obsolescence".

But really Apple should probably be more transparent about this. And the bottom line for users is that if you notice any kind of significant performance degradation, whether it is fast battery drainage or sluggish performance, you should consider taking the phone in.

Apple has decided that people want to buy razorthin phones and there is just not way to fit a large battery in there. I wish there were phones built like the old IBM thinkpads. Bulky, square, ugly but also indestructible and fully user servicable with replaceable batteries.

Not thin; light. Phone makers make phones lighter so that people can hold them up longer before their hands get tired. A battery is massy, however dense it is, whatever the shape. You can only add so much battery before your phone gets too heavy to comfortably hold. (Unlike, say, an external camera lens, which increases volume but not really mass.) Thinness is just a side-effect of lightness, because the alternative—…

>Not thin; light.

An interesting thought, but is it true? I cant really think of people complaining of arm fatigue from holding up a ~150-200g phone -- the effort of holding up your arm and hand alone are going to be substantially more than additional weight of the phone.

I also dont really see any evidence of phone manufacturers decreasing weight over the years, at least with a quick review of Apple's iPhones, which have definitely increased in weight over the past decade.

The problem here isn’t that iOS throttles the CPU when your battery can no longer properly power the phone. (This is a really nice feature, compared to, e.g., sudden shutdown when voltage drops too low to run the CPU at normal speed.) The problem is that iOS doesn’t alert you about what’s happening. If it said something like, “Your battery needs to be replaced. Until it is, your phone will run with reduced speed.” Th…

It does do that.. it tells you your battery needs servicing.

Maybe it warns when the problem gets more severe. But the problem described here is when the battery still has as much as 80% capacity.

Source: I have 6s+, noticed it was slow recently, after some updates but not right after. Read about this. Got GeekBench and battery test. It tests normal when the battery is full, slower when battery is less full.

Another idea: Apple could pop up a dialog at a certain point saying your battery is sub-optimal (but not doomed) and you should replace it for the best experience. I’m sure that would go over GREAT.

That would cost Apple a lot if those people had Apple Care. Better for Apple if the minority people who perceive a problem come in and ask for a replacement/

They can just exclude normal battery wear, or they could increase the price of iPhone Apple Care to include one free battery replacement and then advertise that you're basiclly getting a free battery.

The solution is a battery you can replace, like every phone used to have. There aren’t only two solutions to this problem. (Technically you can still replace the iPhone battery, unfortunately it isn’t trivial like in the bad old days when phones didn’t have high def touch screens.)

This isn't a solution. It's a trade off like every other decision.

You can replace the batteries at both Apple stores and independent retailers. https://www.cnet.com/how-to/iphone-battery-replacement-diy-o... The issue IMO, is it's not obvious that the battery needs to be replaced and when. It's not holding charge > new battery is far more obvious than it's slow > new battery. Most people probably prefer a slow phone than one without charge however Apple should have some indication…

You really can't though. I had a phone with an awful battery-- it would shut off around 25% randomly. I brought it into Apple 3 times, it even had apple care-- and because the f *ing diagnostic suite identified the battery as good, they wouldn't replace it. They wouldn't even LET ME PAY FOR THE REPAIR.

Agreed. I've been in 3 times. Every time I want to just pay for the replacement; they won't even offer the battery replacement if the diagnostic utility says the phone is good.

My phone randomly shuts down or rapidly loses battery once it is below 40%. It's even worse when it's cold.

There may be cases where it does, but it doesn’t seem to do so in this case — at least not where very many of the affected people can find it.

(Myself included. I’ve been noticing for a while that my 6 Plus was running dog slow. Thanks to all this coming out last week I just replaced my battery using a kit from Amazon, and indeed, it now runs well again.)
