Touch the Black probe to the component pad or signal line you want to test.
Measure the test point near the sub-board flex connector to confirm 5V is arriving from the USB port. 📱 Official Technical Resources Phone won't charge, slow
: A visual map of the physical logic board. It helps you locate exactly where a specific component (e.g., C1204 or R2105 ) is positioned.
What the phone shows (blinking light, vibrating, completely dead)
For those looking to repair or understand the internal architecture of the realme C11
Probe the large capacitors surrounding the PMIC and Charging IC. You should read roughly 3.7V to 4.2V. They trace common lines like VBUS, VBAT, Backlight,
Locate the main system rail coil near the PMIC. Verify if the system voltage matches the battery voltage.
If the phone charges slowly, check the continuity of the Data Positive and Data Negative lines running from the charging port to the CPU. 3. Display and Backlight Failures
If the phone gets hot or shows a short circuit when using a DC Power Supply, you can find the faulty capacitor.
