【今すぐオフ】iPhoneの自動アップデートが11月から勝手にオン…外で更新していない人も、スマホ代が高額に？今すぐ確認を！

Summary

Mizuki Nozomi warns that automatic iPhone updates may use mobile data, potentially consuming a monthly data allowance or resulting in extra charges or slower speeds. The video says that an “Automatic Updates” screen mentioning Wi-Fi does not, by itself, determine which network updates use; it points to a separate Data Mode setting.

The presenter also claims that an upcoming November update may turn automatic-update switches back on, including switches users previously disabled. The video presents this as a reason to check both settings locations. Its claims about update behavior and costs have not been independently verified here.

Settings guide shown in the video

1. Turn off automatic update options

   • Go to Settings → General → Software Update → Automatic Updates.
   • Turn off Automatically Install under iOS Updates, Automatically Download if it appears, and Automatically Install under System Files.
   • The presenter says updates will still be available to install manually, such as while connected to home Wi-Fi.

2. Enable Low Data Mode

   • Go to Settings → Mobile Service/Cellular → Mobile Data Options → Data Mode.
   • Select Low Data Mode. If the device instead shows a Low Data Mode switch, turn it on.
   • The video says this setting can restrict automatic updates over mobile data, including app updates, even if the first set of switches is later re-enabled.

3. Check data-use figures

   • Return to the Mobile Service/Cellular screen and scroll to Current Period.
   • Check App Store and System Services for data attributed to app and iPhone system activity.

The presenter recommends checking the automatic-update switches again after the November update and reviewing the same settings on family members’ iPhones.
