The cold weather will shrink and the hot weather will rise again. The value of apples is conservative, generally only deducted. After the recent update, the numerical algorithm is updated, and the compensation correction algorithm may be added. However, after all, battery performance exists objectively and does not come out of thin air.
IPhone 1 1 encountered an inaccurate battery health report. It is reported that the symptoms of this problem include unexpected battery consumption behavior, and in a few cases, the peak performance capacity is reduced. These inaccurate battery reports cannot reflect the actual battery health problems. The maximum battery capacity is determined by a set of algorithms and data measured during battery use. Over time, these algorithms can be updated to provide the most accurate estimate of the maximum battery capacity.
IPhone 1 1 users will automatically recalibrate their batteries if they upgrade to iOS 14.5 Beta6 or later. This calibration process may take several weeks, and during the recalibration process, the displayed maximum capacity percentage will remain unchanged. Peak performance capacity may be updated, but most users may not notice it. When recalibration is completed, the maximum capacity percentage and peak performance capacity will be updated.
Battery health:
That is, the effective total capacitance ratio of the battery, and part of it is the average ratio within the effective service period of the battery, or the expected service time.
When the battery usage strategy changes, the power consumption calculation and battery optimization procedures change, which will change the health status of the battery. After updating the new system, it is found that the health of the battery has increased. This is a rare event.
The battery is a consumable, and the longer the battery cycle is broken, the lower the effective actual total capacitance of the battery will be. However, the indicator of health is not just a total capacitance. The health of the battery comes from the data of the control chip on the battery line, and the battery optimization program will be changed when the system is updated.
