Why do the battery health levels displayed on iSi and mobile phones differ?

Frequent users have found that the data used to detect battery health is different from what is displayed in the iPhone settings.

As shown below:

Why does the battery health display displayed by AISI differ from that displayed on the iPhone?

Regarding the problem of inconsistent battery health between iPhone and AISI, it may be due to the following reasons:

1: Algorithm difference

Different applications or systems use different algorithms when calculating battery health, which will lead to inconsistent display results.

2: Measurement time point difference

The health status of the battery changes over time, and different applications or systems may perform battery health testing at different times, which will also lead to differences in display results. .

3: Hardware Differences

The battery hardware used in each brand or model of mobile phone is different, and there are differences in design and process. These factors may affect the evaluation and evaluation of battery health. calculations, and ultimately lead to differences in display results.

In fact, the 1%-2% difference between the battery health displayed on the AISI display and the iPhone display is a normal fluctuation! If the difference between the two is too large, it is recommended to use one-click flashing to re-check the battery.

You can also re-calibrate the battery in the phone settings. The calibration method is as follows:

Open "Settings" > "Battery" > "Battery Health" and click "Recalibrate".

After startup the system will automatically calibrate through daily use, a process that may take several weeks. Once the recalibration is complete, the maximum capacity percentage and peak performance capacity will be updated and the recalibration information will be removed, indicating that the process is complete.

In addition, the battery health is only an approximation, it does not fully reflect the true condition of the battery Condition. Therefore, we cannot completely rely on battery health to judge battery life. We also need to consider other factors, such as usage time, number of charges, etc. In daily use, we should pay attention to using mobile phones rationally and avoid frequent charging and excessive discharge to extend battery life.
