iPhone battery status information not accurate, tests show | NoypiGeeks (2024)

Remember the iPhone battery fiasco about 3-4 years ago? You know, the one where Apple was accused of deliberately slowing down iPhones as battery deterioration and not informing users, forcing them to upgrade to a new one? That's one of the reasons why they added battery status to iOS.

Information about the battery status of the iPhone can be found under Settings > Battery > Battery status. It shows a number that starts at 100% and decreases as the battery inevitably deteriorates over time.

It also has a report showing whether your battery is still at "Peak Performance Capability" or already needs to be replaced.

The point is to give the user an idea of ​​whether the performance drop they are experiencing is due to the battery. The problem is that the battery health report doesn't seem to be accurate.

Adrian Kingsley-Hughes uitZDNetdid the test on himiPhone 13 Pro Max. After owning the device for 104 days, the device's Battery Cycle Count data shows that it has completed 92 charging cycles.

According to Apple, the iPhone's battery can retain 80% of its capacity after 500 full charge cycles.

This means that Hughes' battery status should now be less than 100%. However, the battery status information says it is still 100%.

Hughes did some research and found that the device's maximum full charge capacity is 4,523 mAh, which could be from the first charge, while the minimum full charge capacity is 4,255 mAh, which could be the most recent charge.

This means that the battery is starting to deteriorate. The question is why iOS still shows the battery status is still at 100%.

Hughes explains that the nominal capacity of a battery, on an iPhone or not, is theoretical. Some batteries have more capacity, others have much more. “The more capacity there is above the theoretical nominal capacity, the longer it takes before the counter ticks from 100 percent to 99 percent. It's all potluck."
