A Reddit post from last week has sparked a discussion regarding iPhone performance as a function of battery age. While we expect battery capacity to decrease as batteries age, we expect processor performance to stay the same. However, users with older iPhones with lower-than-expected Geekbench 4 scores have reported that replacing the battery increases their score (as well as the performance of the phone). What's going on here? How many phones are experiencing decreased Geekbench 4 score?

To answer these questions I've plotted the kernel density of Geekbench 4 single-core scores for the iPhone 6s and the iPhone 7 running different versions of iOS. Scores obtained in low-power mode are not included in the distribution.

Evidence seems to be mounting that Apple is decreasing the clock speed of iPhones with decreased battery capacity to maintain the advertised battery life.

Plenty services offering replacement batteries.

You did know Apple sell 'non-replaceable' batteries in their phones and we know batteries in phones only really last about 18 months in the real-world.

So really did you just ignore this issue when you selected a Apple Phone?

It's not like the iPod battery fraud haven't happened already in the past... People who learned their lesson would have chosen a smartphone with replaceable battery. Still using my 2008 Nokia N95 and 2011 HTC Evo3D with no performance loss, just changed the batteries when they went belly up.

Trouble is there are millions of people who don't know the battery is an issue at time of sale.
Sure, you tell them 2 years later and they're really annoyed. But it's the buyer's problem. They don't ask and they're not told.

That's demonstrably not universally true - in my secondary phone there's a 12 years old battery which shows little wear, still lasts over a week.
