Power Management IC (PMIC) Repair: Estimated Labour Charges and Prices in Nairobi
Provider: Pro-Logic Technologies, Kangari Building, Nairobi
The Power Management IC (PMIC) is one of the most critical chips on a smartphone's motherboard. It regulates the distribution of power from the battery to every component on the board — ensuring each chip, sensor, and circuit receives precisely the correct voltage and current. When the PMIC fails, the effects are wide-ranging: the phone may refuse to charge, fail to power on, reboot randomly, overheat without cause, or show symptoms that appear to indicate multiple unrelated faults.
Symptoms of PMIC Failure
- Phone does not power on; battery and charging port are confirmed healthy
- Phone charges but immediately dies when unplugged
- Multiple components (camera, cellular, Wi-Fi) fail simultaneously
- Abnormal heat from a specific area of the board near the battery connector
- Phone only powers on when connected to a charger and dies the moment it is removed
- Voltage output tests on the board show incorrect or absent rails
PMIC failure is one of the most commonly misdiagnosed board-level faults, often confused with battery failure, charging port failure, or even software issues.
Estimated PMIC Repair Costs in Nairobi (2024–2025)
| Device Category | Labour (KES) | Parts (KES) | Total Estimate (KES) |
|---|---|---|---|
| Budget Android (MediaTek devices) | 3,000 – 6,000 | 1,500 – 4,000 | 4,500 – 10,000 |
| Mid-range Android (Snapdragon/Dimensity) | 4,000 – 8,000 | 2,500 – 7,000 | 6,500 – 15,000 |
| Samsung Galaxy S-series | 5,000 – 10,000 | 4,000 – 10,000 | 9,000 – 20,000 |
| iPhone (6 through XR) — U2 / Tigris PMIC | 4,500 – 8,000 | 3,000 – 8,000 | 7,500 – 16,000 |
| iPhone (11 through 15 series) — integrated PMIC | 6,000 – 12,000 | 4,000 – 12,000 | 10,000 – 24,000 |
PMIC replacement requires precise BGA rework skills. Incorrect installation voltage can permanently damage adjacent chips. This repair should only be performed by a specialist micro-soldering technician.
Why PMIC Repairs Are High-Value
Successfully replacing a PMIC can restore a phone that appears completely dead — making it one of the highest-value board-level repairs available. A phone that is otherwise in excellent cosmetic condition and would cost KES 40,000–80,000 to replace can often be restored for KES 10,000–24,000.
Pro-Logic Technologies at Kangari Building, Nairobi performs PMIC diagnostics using voltage testing equipment to confirm the fault before any chip replacement is attempted.
