Normal value of ipad battery health
The battery health of IOS system is based on the effective capacity of the battery, and the current availability rate of the battery is calculated by comparing the rated capacity. The approximate calculation formula is: effective capacity ÷ rated capacity = available capacity ratio. If it is a new machine, the battery loss is below 5% to be normal, and it will be 30% after a long time, and it can still be used normally.
However, we need to be clear that if it exceeds this value, it will have an impact on the life of the ipad, so it is necessary to consider replacing the battery. Battery health means that with the use of ipad, the maximum capacity of the battery will gradually decrease. If the battery capacity is less than 80%, the ipad's processor will be down-frequency, which will affect the jam.
