Schedule when downloaded updates install
Lets a downloaded system update install automatically overnight or at a chosen time instead of immediately, so the required restart doesn't interrupt active use of the phone.
How to open Scheduled System Update Installs
- Open Settings → System → System update
- Download the available update if not already downloaded
- Choose 'Install tonight' or a similar scheduled option when prompted
- Leave the device charging to allow the scheduled install to complete
What you should know
- Common options include 'install now' or 'install tonight'
- The device typically needs to be charging and idle for scheduled installs to trigger
- Reduces the chance of an update interrupting active tasks or calls
- Presented as part of the system update notification or installation prompt
Why it matters
System updates require a restart, which can be disruptive if it happens in the middle of active use. Scheduling installation for overnight or idle periods ensures the device is ready and fully updated by the time it's needed again, without forcing an interruption during the day. This is especially useful for people who use their phone continuously for work or communication and don't want an update prompt derailing an important task.
Best practices
- Choose the overnight install option so updates complete without interrupting your day
- Keep the phone plugged in overnight when a scheduled install is pending
- Avoid repeatedly postponing updates, since delaying too long can leave security gaps
Common problems and fixes
- Scheduled install didn't happen overnight
- Confirm the phone was charging and had sufficient battery, since scheduled installs typically require both conditions.
- Phone restarts unexpectedly during the day
- Check if 'install now' was previously selected instead of a scheduled time, or if the deferral window expired.
- Update keeps getting postponed automatically
- Manually select 'install now' if repeated automatic deferrals are preventing the update from completing.
Tips and tricks
- Plug your phone in before bed on nights you know an update is pending
- Check the system update page in the morning to confirm a scheduled install completed successfully
Frequently asked questions
Can I choose a specific custom time for the install?
Most devices only offer a general 'tonight' or 'now' choice rather than a precise custom time picker.
Does a scheduled install still require my approval first?
Typically yes, you approve the update to begin download, and scheduling only affects the timing of the final restart and install.
What happens if I never approve the update at all?
The device will continue reminding you periodically, but the update won't install until you take action.
