How a Faulty PMIC Causes Power Issues in Samsung Phones (And How to Fix It)

The Power Management IC (PMIC) is the “heart” of your Samsung Galaxy’s power system. When it fails, you’ll experience frustrating issues like:

🔧 Common PMIC Failure Symptoms:

Why PMICs Fail:

1. Water damage (corrosion on circuits)
2. Power surges (from faulty chargers)
