As of my last knowledge update in September 2021, you can update iPhone apps in bulk using the App Store on your device. Here’s how you can do it:

- Unlock Your iPhone: Ensure your iPhone is unlocked and you’re on the home screen.
- Open the App Store: Tap on the “App Store” icon, which is typically a blue icon with a white letter “A” on it.
- Navigate to the “Updates” Tab: At the bottom of the App Store, you’ll see several tabs. Tap on the “Updates” tab. This will show you a list of all the available app updates.
- Update All Apps: If there are updates available for multiple apps, you’ll see an “Update All” button at the top right corner of the screen. Tap on this button to update all apps simultaneously. You may need to enter your Apple ID password or use Face ID/Touch ID to confirm the updates.
- Individual Updates: Alternatively, you can update apps individually by tapping the “Update” button next to each app’s name. This can be useful if you want to prioritize some apps over others.
- Wait for the Updates: Your iPhone will now download and install the updates for the selected apps. The progress can be monitored on the app icons on your home screen, as they will show a progress circle around them.
- Automatic Updates (Optional): You can also enable automatic app updates in your iPhone’s settings. To do this, go to “Settings” > “App Store” > and toggle on “App Updates.” This will allow your iPhone to automatically update apps in the background when new updates become available.
Please note that the steps and options may vary slightly depending on your iPhone’s iOS version and any updates or changes made by Apple since my last update in September 2021. Always ensure you have a backup of your important data before performing updates, just in case anything goes wrong during the process.
