Part 2. How to Fix Screen Lock Delay on iPhone
2.1 Adjust Click Speed of Side Button
If you are using iPhone X or later, Apple allows you to customize the speed of double or triple clicking the Side button, which means that your iPhone delayed lock screen when mistakenly pressing the Side button. Hence, go to Settings → Accessibility → Side Button → Default. If you chose Slow or Slower here, the laggy screen will occur when locking and unlocking iPhone. If this problem exists on other models, read the other methods to solve it.
2.2 Turn Off Low Power Mode
It is true that Low Power mode extends the battery life of your iPhone and makes it healthier. But it will slow down the operating speed and disable some features, so your iPhone cannot be used at its peak performance. As a consequence, your iPhone screen delays locking. You only need to head to Settings, scroll down to Battery, and toggle Low Power Mode off.
2.3 Change Settings of Side Button
Still for the models after iPhone X, just as mentioned before, there are accessibility options set up for the Side button. By default, double-press opens Apple Pay while triple-press activates the feature you set in Accessibility Shortcut. You could disable the two features and solely use the Side button for locking and unlocking. Enter Settings, find Wallet & Apple Pay, and turn off Double-Click Side Button. For triple-click operation, locate Accessibility on Settings, scroll down to Accessibility Shortcut and check if there is a blue tick. If there is one, tap the option to disable it.
2.4 Use iPhone under Appropriate Temperature
When you use your iPhone in a too-hot or too-cold place, or your iPhone is getting hotter because of long time using or too many apps running, its speed and performance are inevitably impacted, as well as the screen locking process. So, go to a place with an appropriate temperature and let your iPhone calm down or become warmer.
Moreover, consider closing some apps you don't need to use recently. On the Home screen, swipe up from the bottom and scroll up to exit some apps if you are using iPhone without a Home button. Double press the Home button and swipe them up if your iPhone possesses a Home button.
2.5 Check Battery Health
Battery life will influence the response of locking and waking up the screen. Although this is unreversible, you could check if the rechargeable battery is severely harmed so as to cause the iPhone screen lock delay. Open the Settings app, select Battery, tap Battery Health, and look at the Maximum Capacity. If the capacity is extremely low, your battery is recommended to be replaced.
2.6 Check Device Storage
Insufficient storage also possibly slows your iPhone down and lock your screen lugged. Thus, you need to check the storage and optimize it by removing some items. On the Settings app, choose General, find iPhone Storage, read the sentence under RECOMMENDATIONS, and tap the Enable option. If there are no recommendations or the storage remains inadequate, you could choose a certain app to offload it or delete it.
2.7 Restart/Force Restart iPhone
I suppose that you already tried to restart your iPhone. To deep refresh your iPhone and fix the screen lock delayed glitch, it is worth force restarting it. Here is how to do it.
- iPhone 8 and later: press and release the Volume Up button, do the same to the Volume Down button, and hold the Power button until the Apple logo appears
- iPhone 7 and 7 Plus: press and hold the Volume Down button and the Power button, release them when you see the Apple logo
- iPhone 6 and earlier: hold the Home button and the Power button, and release them once the Apple logo occurs
2.8 Reset All Settings
It is recommended to reset all settings if you have no idea which step to remedy. The operation is easy. Navigate to Settings, tap General, scroll down to Transfer or Reset iPhone, choose Reset, select Reset All Settings and enter your screen passcode to continue. After that, you could see if your iPhone screen could be locked smoothly.
