I was told recently that my iPhone’s battery health has just dropped to 79% and had to be replaced, while on Coconut Battery said it still has 83% in which the difference is quite big.

While I understand the figures can’t be accurate, I am curious about how they estimate it.

My phone’s battery degrades fast due to last year’s wireless charger and recent iOS 26 update which brings more heat.
