Q2: The battery cannot be fully charged:

The higher the power of the charging head, the better. For example, use a fast charging head that supports PD protocol or QC protocol.

Q3: When charging the phone from the front, it shows 52%. When you pull it out and put it back, it shows 98%. What is the principle?

A3: This is virtual power, you need to discharge the power and then fully charge it again. The power output is inaccurate at the beginning and needs to be cycled 2-3 times

The cycle is to discharge to 0 and recharge to 100. after several cycles
