What is the capacity of 78% electricity?

Hello, I'm glad to answer this question for you. The 78% displayed in the upper right corner of the mobile phone is the power of the mobile phone. Because the power of the mobile phone is calculated by percentage, the remaining percentage of the power will be displayed. The 78% battery health of Apple's mobile phone reflects the battery health of the mobile phone. More than 70% of Apple phones are relatively healthy.
