IPhone battery health percentage is not that accurate

According to a YouTube channel that studied how the iPhone assesses its battery condition, the percentage of iPhone battery health that declines over time is irrelevant and misleading because it does not identify capacity. actual battery.

Following public criticism of silently limiting device performance to avoid sudden shutdowns, Apple began revealing battery health percentages on iPhones in 2018. This has been factored in until present to determine how long an iPhone can be used before it needs repairs.

It is common knowledge that not all batteries are created equal. Batteries have a wide range of capacities due to the chemical processes that take place in the production of energy.

A video uploaded by Piet Forward’s YouTube channel shows that the new iOS 11.3 battery health percentage is unusable and, therefore, a hoax.

When determining the percentage of health of an iPhone, Apple does not take the rated capacity into account. Here’s when things get risky.

The difference in maximum capacity between the two iPhone models does not reveal the actual age of the batteries. The iPhone 12 Pro has 97 charge cycles compared to the 466 charge cycles of the iPhone XS, which explains the discrepancy.

When the video was made, the narrator used two different iPhone models to show the differences between the two. When it comes to storage space, the iPhone XS has around 83% of what the iPhone 12 Pro seems to have:

Additionally, Piet Forward has an idea of ​​why Apple would advertise 100% battery health despite the iPhone 12 Pro having 97 charge cycles. Lithium-ion batteries degrade dramatically with each complete charge cycle, according to Apple Paul.

According to the presenter’s iPhone study, Apple does not currently use actual capacity to determine the percentage of battery health and instead uses the nominal capacity to estimate the battery life available on the iPhone. Apple. Under some circumstances, the actual capacity may be greater than the stated capacity, allowing you to display your iPhone at 100% capacity for a short time even after multiple charge cycles.

In other words, it’s like putting gasoline in your automobile… With a gasoline gauge, you fill it up and it goes over F and it’s a long time – a lot of gasoline goes back to F ”, adds the narrator. Everything is digital today. ZDNet has now removed the video, which was first posted in April.
