Your Mac’s result, being so new, remains to be seen. I don’t think a month can tell us much yet. Interestingly, I do think that time is a pretty significant factor, too. My only Mac is a barely used 2015 MacBook Pro. It has 90% health with… 140 cycles. That’s horrible, but it’s nine years old!
It’s a more extreme example of my Xʀ. Like I said earlier, heavily used iPhone 8: 76% and 2250 cycles. Lightly used iPhone Xʀ: 89% and 360 cycles. For a good health-to-cycles ratio, the best “tip” I can give is… cycle it a lot, as quickly as you can! I have a usage pattern that’s either too efficient (my iPhone 16 Plus lasts 27 hours of SOT on iOS 18 and I won’t ever update it, so even using it 6 hours a day won’t cycle it quickly), or the device has barely been used and the time ratio is bad (like the Mac).
You have, on your 15 Pro since May 2024, 391 cycles, for a monthly average of 26.06 cycles/month. My 16 Plus has 51 cycles (let’s assume 53 until Sept 5, exactly 6 months), for an estimated monthly average of 8.83 cycles/month.
In the looooong term, I can assure you that there’s a massive likelihood of you having a better ratio than me. The secret is to use it and cycle it a lot. It’s quite unlikely that a heavy user will see a poor ratio. Sure, sometimes I see, once in a blue moon, somebody saying that their iPhone dropped to something ridiculous in a year, but it is unlikely.
What I will have, naturally, is better battery health if I only include time. Less usage, less battery degradation.
