I'm not sure what the right move is here. Apple does have a notification once the battery reaches some threshold of "bad". But maybe it's too conservative? Clearly, notifying an iPhone customer that their battery is going bad when they're throttling CPU by 1% is too aggressive. 75% is too late. Where the right number lies, I don't know.
I ran the benchmark and my phone is affected (showed 1650 and 3000 when it the average for my phone is 2400 and 4000). I went into the battery menu people are saying that this notification shows up and there is nothing there about my battery needing to be replaced or serviced.
