02. Disable AssistiveTouch Feature

The AssistiveTouch feature on an iPhone allows users to access various device functions. This feature can be especially useful for individuals who have difficulty using physical buttons or gestures on the device.

In terms of auto-lock, the AssistiveTouch feature should not have any direct impact on its functionality. However, what if this feature is constantly being used or accidentally triggered? Then, it could potentially prevent the iPhone from going into auto-lock mode and draining the battery.

So, you are supposed to ensure that the auto-lock feature works properly while using AssistiveTouch. Therefore, it’s important to periodically check that the device screen is turning off after the selected period of inactivity. So, you may disable the AssistiveTouch feature to see if it resolves the issue.

03. Deactivate Low Power Mode

Low Power Mode is a function on iPhones that reduces the device’s power consumption. It does so by disabling certain non-essential functions and limiting performance.

In some cases, Low Power Mode may disable the Auto Lock feature. This occurs if the device’s battery level is extremely low and Low Power Mode is activated as a result. When this happens, the device may stay on indefinitely until it’s charged or Low Power Mode is turned off.

Let’s assume that you’re experiencing issues with the Auto Lock feature while Low Power Mode is enabled. So, you may want to try disabling Low Power Mode temporarily to see if it resolves the issue. Keep in mind that this may impact battery life. So, it is best to use Low Power Mode sparingly and only when necessary.

  • Open “Settings” and select “Battery“.
  • Go to “Low Power Mode” and toggle its switch to disable.
