Reset your device by holding the Sleep/Wake and Home buttons for 10 seconds
If your iPhone 4 is unresponsive or frozen, you can reset it by holding the Sleep/Wake and Home buttons for at least 10 seconds. This process is known as a ""hard reset" and can bring your device back to life.
Here's a step-by-step guide on how to perform a hard reset on your iPhone 4:
- Press and hold both the Sleep/Wake button and the Home button simultaneously. Ignore the red slider if it appears.
- Continue holding both buttons for at least 10 seconds. You may need to hold them for up to 15 seconds.
- Release the buttons when the Apple logo appears.
- Allow your device to restart.
This process will not delete any of your data or settings, but it will forcefully close any problematic apps and bring your device back to a responsive state. It is a good solution to try if your iPhone 4 is feeling slow or unresponsive, or if apps are freezing or crashing.

Adjust the timing of your iPhone's auto-lock feature in Settings
If you want to adjust the timing of your iPhone's auto-lock feature, you can do so in your Settings. The auto-lock feature automatically turns off your display and locks your device after a set period of inactivity. This helps to preserve battery life and keep your device secure.
To adjust the auto-lock timing, open the Settings app on your iPhone. From the Settings menu, tap on 'Display & Brightness'. From here, you will be able to see the 'Auto-Lock' option. Tap on this to adjust the settings. You can choose from a range of options, typically from 30 seconds to 5 minutes, depending on your preference. You can also select 'Never' if you want to turn off the auto-lock feature completely.
If the auto-lock option is greyed out in the settings, it means that your iPhone is in Low Power Mode, which forces auto-lock to remain at 30 seconds. To change the auto-lock time, simply turn off Low Power Mode. You can do this by asking Siri to "Turn off Low Power Mode", or by manually turning it off in your settings.
Once Low Power Mode is off, you can go back into your Display & Brightness settings and change the auto-lock time to your preferred option.
