Usually, after receiving a new battery, don't tidy up the cable, just connect the mobile phone first, don't close the cover, connect the charger and observe the change of charging capacity. If the power can be increased normally and exceeds 5%, it means that the cable arrangement is normal, and subsequent operations such as installation and gluing can be carried out.
Reasons for cable arrangement: abnormal conditions such as no startup, no charging, constant power, etc. occur, and the cable arrangement is damaged (unable to send data to the mobile phone). After the cable is not shaped, damaged, glued and the battery is not covered, return the sold battery to the store for testing to confirm whether it is the battery itself.
If the new battery is good, the cable plates of the old battery and the new battery can be exchanged, so that the new battery can also be charged.
