Hello!

This is iPhone Repair Worker Shinjuku Main Store.

Our store, located right near the east exit of Shinjuku Station, sees many customers every day coming in for help with their iPhone problems.

Today, we'll delve into the causes and solutions to a problem we received from an iPhone 12 user: "Unstable charging makes it difficult to use."

■ Is the need for angle adjustment a sign of malfunction? The iPhone 12 brought in this time was very unstable, sometimes responding and sometimes not when the charger was connected, and charging wouldn't start unless it was firmly pressed or tilted to a specific angle.

Many of these symptoms are caused by physical deterioration or damage to the "dock connector," which is the charging port. Several years have passed since the release of the iPhone 12 series, and an increasing number of units are experiencing accumulated wear on the terminals due to daily plugging and unplugging.

It is especially dangerous to continue using a device that only responds when held at a specific angle. Forcing power through a poorly connected device can cause sparks inside the connector, potentially short-circuiting the circuit board itself. Furthermore, if the terminals break completely, the battery may run out before you can back up your data, increasing the risk of losing access to important information.
