Yup, sure enough, iPhone shutdown at ~18% (as it has for ages!) and when I rebooted, I was told I was in battery performance management mode. For the past few days the iPhone has been laggy and a pain to use. Turned that mode off and it's buttery smooth again.
Hmmm, was it just PR about the "throttling" then? The performance management spiel might be true and technically get better use from the battery, but it makes the iPhone a bore to use and certainly 'nagged me' to upgrade. With it turned off, I'd rather simply a new battery and keep going. It works just fine!
