IPhone battery health confirmed to be meaningless

Apple shows iPhone battery health since iOS 11.3 in 2018

The percentage of iPhone battery health that declines over time is a meaningless estimate as it does not determine the actual capacity of the battery.

Apple started showing Battery Health% on the iPhone after sparking public outrage in 2018 for quietly sabotaging their phones’ performance to trigger shutdowns.

But it has been established that not all batteries have the same capacity. Due to various chemical reactions that take place during power generation, batteries have varying capacity levels.

But instead of being honest about the variation, Apple is just rating that all iPhone batteries are the same.

A video posted by the Payette Forward YouTube channel proves that iPhone Battery Health is nothing but a scam.

The video considers two iPhone models: the iPhone XS and the iPhone 12 Pro. While the iPhone XS displays 83% of its maximum capacity, the iPhone 12 Pro appears to have 100% of its capacity.

Changing the maximum capacity does not reveal the exact age of the batteries in both models. The only difference is that the iPhone 12 Pro underwent 97 charge cycles at the time of testing, compared to 466 charge cycles for the iPhone XS.

Why would Apple show 100% battery health on the iPhone 12 Pro despite 97 charge cycles? Apple itself says that “with lithium-ion batteries the capacity decreases slightly with each complete charge cycle.”

The answer is that Apple doesn’t take actual capacity as the basis for calculating battery health and instead uses nominal capacity to estimate how much battery life is left on an iPhone. Actual capacity may be greater than rated capacity.
