At what percent of battery health does throttling starts?

As above .. very disappointing.

No one knows yet.

Well Apple say they’ll replace batteries at 80% capacity.

Mine was doing it with a battery that reported 93% life on Apple's diagnostic and Coconut Battery was reporting about 79% for the same phone. I don't think it can be correlated to what the checking utilities report.

There are many, many variables as to why Apple’s diagnostic will differ to Coconut battery. For starters, coconut battery is real time and Apple is an average over a set amount of time. That alone can have massive discrepancies. In a sense, Coconut battery is even more accurate than Apple’s own test.

Like someone said, no one knows. But what we do know is that Apple decides to increase throttling only through updates. So, whatever health requirements they require can change from update to update... at least, that appears to be the case now when they did not alert the user.

Not sure on my 6S+, I have a battery app reporting 80% health and mine sure does throttle, and bad at times.
As an example, I have used it for 5 hours out of 7 today, battery was at 37% and the CPU at 911 Mhz! Proper rubbish.
So I plugged it onto my Zendure A2 and around 42% battery it had come up to 1512 Mhz, however it stays there for a long time before going back to 1848 Mhz, this then seems to change a lot going from that to maybe 1800. Its crazy BUT, before I started watching it, I could never say I had noticed anything bad whilst using my phone.
It never seemed sluggish or slow so for me, it's just numbers really. I do wish I hadn't ever looked though, LOL.

I have a 6s in the house that shows 87% health and will throttle when charge gets below 70%. We have another one that shows 82% and is throttled all the time , even at 100% charge.

I think they wanted to introduce a new feature that tells you about the battery state in spring, let's hope for the best

Mom’s iPhone 6S Plus with 77% battery life reported on Coconut Battery on macOS absolutely does not throttle. It also does not shut down abruptly. I get consistent GeekBanch scores even if the battery level has gone down to 10%.

At the point where Apple believes it's time to start creating "long in tooth" sentiment to motivate users toward buying a new iDevice.

Yeh it’s a weird thing. I never even thought about slow down until the news articles about the throttling started to appear. So whilst I can prove it’s occurring on my 6S Plus I just use the phone anyway as normal. I will say that Geekbench scores do change in mine as it’s throttled back.

My 6s started throttling at 87% battery life left, it would start at about 60%. If I kept the phone charged above 60% I’d get almost perfect benchmarks
