Schematic for the Infinix Note 8i smartphone, packed in a 1.62 MB zip archive. The name gives no board revision or variant, so compare the layout with the actual handset before relying on it. Phone schematics like this help trace charging, power management and display circuits, find the path from the battery connector to the PMIC, and check supply lines when hunting for a short. Most are PDF sheets readable in any standard viewer, sometimes with block diagrams of the main sections.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @phoneSchematics. Enginerys does not host this file.
