The \"iron sheet\" on the battery is a nickel sheet, which connects all the batteries according to the required voltage and capacity, or in series or parallel, to form a battery pack. If it falls off, it will affect the capacity of the battery pack or lead to an open circuit of the battery pack and cannot be charged.

The role of the fixed iron plate of the mobile phone battery is very large. It plays a fixed role of the battery, and it is also a conduction role of the battery's abdominal muscles. On both sides of the battery, a section of the size of the side seam is positive, and there is a contact in the middle, and the negative electrode is pressed by this iron sheet and conducts electricity. Is very useful, unchangeable.
When the battery is full, the phone automatically cuts off the charging circuit to avoid overcharging the battery. In addition, when the battery is out of power, it automatically prompts the battery is low, and makes the software automatically shut down.
The metal plate is connected to the battery cable port, and the iPhone back cover also has metal, so after the back cover is installed, the metal plate is to connect the internal battery port and the metal on the back cover. It should be conductive, so that it can avoid the leakage of electricity in the mobile phone, and the working principle of the lightning rod is similar, so that the mobile phone is also safe
