That doesn't support the assertions you are making. The capacity tests are just that - measures of how much energy the battery currently stores and the maximum that it can store. The problem at hand (sudden shutdown) is caused by elevated internal resistance.

Apple's refusal to replace batteries that have been less than 20% depleted, even if you're trying to pay them to do it, is stupid and hopefully has now changed.

Your battery may be good and there may be myriad of reasons that slow down your device: defective logic board, water, drop, defective battery are to name a few. Slowness is always a support issue. If you have a slowness problem Apple support is there. As when you're sick you don't heal yourself reading Wikipedia but you go to a physician right? Did Apple refuse to cure the slowness of your device? No because you didn't request that.

Agreed with all of this.

tried to force Apple to comply with your "solution".

You don't think it's totally unreasonable of Apple to refuse to replace the battery? It's not that they were refusing to replace it for free, they were refusing to replace it, even for the $79 fee (which clearly has a VERY healthy profit margin)! Personally, I think that is unacceptable and indefensible.

Read my post. The phone increases its throttle level by battery charge level. What I didn’t mention was that at 100% charge, the CPU is at full speed. Yes.... the full 1850 MHz for the first few minutes of use. By the time the charge drops a few points, we’re at 1500 MHz, and the stutters begin to mount.  Below 90%, it’s usually at 1200 MHz, and from there you can expect it to bounce around from 1200 to 911 MHz until below 70% charge. So for the majority of my day, my phone acts and feels not like a still capable iPhone SE, but like my older iPhone 5S.  The gradual throttling is palpable. I can feel it in the increased lag and stutters as the clock speed decreases. Geekbench and my own fingers prove it. 

How many battery cycles have you had (you can plug your iPhone into a Mac and use CoconutBattery (free) to find this info)? I suspect what you are seeing may be more to do with thermal management than the battery. Certainly, I wouldn't expect the CPU to run at full MHz all the time, regardless of battery status.

Atomic, I doubt your SE is being throttled if your battery is performing at 86% capacity.

I don't know why you are concluding this based on Atomic's comments. He says that he has observed GeekBench scores (and CPU clock speed) decreasing (dramatically) as the battery discharges. Sounds like pretty heavy throttling to me.

entropys said:

Have you considered you have an older generation CPU trying to run the latest generation OS?

Not relevant. Atomic's comments imply that performance is acceptable when battery is full and become unacceptable as battery discharges.

entropys said:

also, if you are so desperate to replace the battery in your out of warranty device, there are any number of mall shops that would do it for you. Heck you could do it yourself!

I will endlessly defend Apple's throttling of the CPU because I think it's a good engineering solution to the problem. However, their (previous) policy of refusing to change a user's battery, even when that user is trying to pay for it, it totally unacceptable. If you want your battery to be replaced, you should be able to have the battery replaced, regardless of the results of any tests. Test results should only influence whether or not you have to pay for the battery replacement (e.g. tests show that battery has aged faster than warranted and therefore should be replaced for free).

Apple should have known better.

All they did was fix a problem.  Now they are being sued for fixing it.

No, they did not fix anything.

OK, so I know that you're probably just a drive-by troll, but I can't help but bite:

feudalist said:

They buried, and now they want as to pay twice for design flaw.

Please could you elaborate on exactly what you think this "design flaw" is/was?

feudalist said:

This is not about aged or depleted batteries

Yes it is.

feudalist said:

because in that case it is implicated that iphone is no better than for a year or so of mild use.

This does not logically follow from your previous statement, and is also total bollocks. One year of "mild use" of an iPhone does not result in its battery reaching the state that requires CPU throttling. One year contains 365 days, and "mild use" would imply one full battery cycle every 1 to 2 days, i.e. about 243 cycles for the year. It takes over 600 to 700 cycles before the battery reaches the point that throttling is necessary.
