Software Troubleshooting第 72 / 100 题

a.Replace the charging port
b.Increase screen timeout
c.Turn off Bluetooth permanently
d.Check data-usage per app, remove unknown apps, and scan for malware
解析
Reviewing per-app data usage, removing unrecognized apps, and scanning for malware targets a likely compromise causing the spike. Charging-port or Bluetooth changes are unrelated to unexplained data consumption.
