The Jio F220B keypad phone is still used by many people, especially for calling and basic work. One common problem in this phone is charging failure. The phone does not charge even when the charger and battery are good. In most cases, the charging IC on the board becomes weak or damaged. Since this phone is old, changing the charging IC is not always easy or affordable. Because of this, technicians use a charging IC bypass trick.
The charging IC bypass trick is a simple repair method used in mobile repairing shops. In this method, the faulty charging IC is not replaced. Instead, charging power is given directly to the battery line using a small wire. This helps the phone start charging again. This trick is very common for keypad phones like Jio F220B where spare parts are limited and customers want a low-cost solution.
Why Charging IC Bypass Is Used
Charging IC replacement needs good soldering skills and proper tools. The IC is very small and there is a high chance of board damage. Many local repair shops do not want to take this risk, especially for an old phone. Customers also do not want to spend much money on such devices. The bypass trick saves time, money, and effort. That is why it is widely used in daily repair work.
Step-by-Step Jio F220B Charging IC Bypass
First, open the Jio F220B phone carefully and remove the battery. Clean the charging port area and check for any visible damage. If the port and battery are fine, move to the charging IC section on the motherboard. Identify the charging input point coming from the charging port.
Next, locate the battery positive line on the board. Use a thin insulated wire for the connection. Solder one end of the wire to the charging input point and the other end to the battery positive point. Make sure the soldering is clean and strong. In some cases, a small diode or resistor is added to control current flow.
After completing the connection, recheck for short circuits. Insert the battery and connect the charger. If the work is done properly, the phone will start charging. Do not rush this step. Always test slowly and carefully.
Real-Life Repair Experience
In real repair situations, many Jio F220B phones come with the same complaint. The customer says the phone was working fine but suddenly stopped charging. After checking basic parts, the charging IC is found faulty. The bypass trick solves the problem quickly. The phone becomes usable again and the customer is happy with the low repair cost.
