iPhone 14 Pro Max iPhone 14 Pro Max Battery Health (After a Year)

[Macbookey]

Now at 88% (11/22) having dropped from 90% after updating to 17.4.

Edit: Make that 87%. SMH

My iPhone’s battery originally performed well. I posted on here praising it! But, it’s dropping faster than a ships anchor the past few months. I’m now at 88% battery health.

Battery degradation is not linear; the capacity will drop a little quicker at first, then the endurance will level off (for the most part), and finish with a nosedive.

Here’s a fair representation of capacity to usage:

Mine too and I got mine on 1/19/2023. Definitely the biggest drop in battery health I ever experienced on a iPhone.

My 9 month old 14 Pro Max has now gone down from 100% to 97%

Its probably going to end up worse than my 12 Pro Max!

Now 92%

December 2022, 94%.

Lunch day device, down to 85% now. I am contemplating if I should buy the new device this year or just get the battery replaced on this one.
