The mobile phone battery is now a lithium-ion battery, which can be charged at any time, intermittent charging is possible. Because the charging cycle of the battery is from 0 to 100%, if only 20% is charged this time, 80% of the next charge will consume a cycle of use. To be conservative, the Apple mobile phone battery can be recycled 500 times, and the battery health can still be maintained at about 80%.
There is no problem with intermittent charging, but after using it for about a week, you need to let the phone go into deep charging and discharging, that is, the phone is fully charged to 100%, and then it is used to automatically shut down, so that you can check the battery health. If you feel that 5V 1A is very slow to charge, all phones after iPhone 8 can use fast charging. Using fast charging will feel a significant increase in the charging speed, and it will not affect the battery life.
