Official schematics for Vivo devices are proprietary and not hosted on the official Vivo website. You must use third-party repositories. Follow this workflow to find them safely:
Avoid random Google search results that promise direct downloads without verification. Instead, check these verified technical communities:
Problem: A Vivo U10 that showed "slow charging" and eventually stopped charging entirely. vivo u10 schematic diagram download better
Using a low-quality schematic (blurry, missing resistor values): The technician replaced the charging IC (U101) twice – no improvement.
Using a better downloaded schematic (clear PDF from a GSM forum): The technician identified that pin 7 of J2601 (BAT_ID) requires a 47kΩ pull-down to ground via resistor R2604. Upon checking, R2604 was cracked (infinite resistance). After replacing it, charging returned to normal. Official schematics for Vivo devices are proprietary and
Lesson: The better diagram saved hours of guesswork and two IC replacements.
Ensure you are looking for the correct file. The Vivo U10 is often a rebranded version of other models. Schematics for Vivo Y11 (2019) or Vivo Y12 may share significant similarities with the U10. Upon checking, R2604 was cracked (infinite resistance)
Many mobile repair communities share "better" versions—cleaned, OCR-processed, and often combined with board views (real PCB photos with overlays). Search for "Vivo U10 Schematic + Boardview."
