Automatic app updates are one of the highest-leverage security settings on an iPhone. Many real-world compromises rely on outdated apps and old bugs. Turning on auto-updates shrinks the time between a fix being released and your phone actually installing it.
Rule of thumb: keep automatic app updates on unless you have a specific operational reason to manage updates manually.
Enable automatic App Store app updates
Labels vary by iOS version, but the control is in App Store settings.
- Open Settings.
- Tap Apps, then App Store (or just App Store on some versions).
- Turn on App Updates.
Apple documents the current settings and what the toggles do: Automatically update apps and games from the App Store.
What the App Store update toggles actually control
| Setting | What it changes | Security impact |
|---|---|---|
| App Updates | Automatically installs available app updates | Security patches and bug fixes arrive sooner |
| Automatic Downloads | Apps purchased on other devices can be downloaded automatically | Mostly convenience, but can surprise you on shared Apple IDs |
| In-App Content | Apps can refresh or download content in the background | Mostly bandwidth and performance, not a core security control |
How to force an update when you need it now
Automatic updates can be delayed for normal reasons (battery, storage, network). If you need to update an app immediately:
- Open the App Store and check the account/profile area for pending updates.
- Update the specific app directly from its App Store page.
- Make sure you have enough storage and a stable network.
Why automatic updates sometimes do not happen
- Low storage: iOS may postpone downloads until there is room.
- Network constraints: some updates wait for Wi-Fi or for a better connection.
- Power state: updates often happen while charging or idle.
- Restrictions or management: Screen Time or mobile device management (MDM) can limit updates.
Automatic updates help, but account security controls the phone
App patching reduces one category of risk. The control plane for an iPhone is your Apple ID and device access. If someone controls your Apple ID, they can change settings, remove devices, or block recovery.

- If you suspect compromise on the device, updating apps is not enough by itself. Use how to check if your phone is hacked to contain and verify.
A practical default
Security improves when patching is automatic and identity is stable. That combination blocks a large share of opportunistic mobile attacks.
If you temporarily disable updates to avoid disruption, do it deliberately and set a reminder to turn them back on. The safest state is not "never update." It is "update without relying on memory."
When app updates are automatic, your security posture improves quietly over time. That is the point: fewer emergencies, fewer surprises, and fewer chances for old bugs to become new problems.
