Step by Step Tutorial: Turning Off Standby Mode on iPhone 15

Before we dive into the steps, let’s understand what we’re trying to achieve here. Standby mode, also known as sleep mode, is a power-saving state that your iPhone enters when it’s not in use. However, there might be times when you want to keep your iPhone awake for longer periods, and that’s where turning off standby mode comes in handy.

Step 1: Open Settings

Navigate to the settings app on your iPhone 15.
Opening settings is your gateway to modify how your iPhone behaves, including managing standby mode.

Step 2: Select Display & Brightness

Scroll down and tap on the ‘Display & Brightness’ option.
This is where you can adjust screen-related settings, such as brightness and screen timeout.

Step 3: Tap on Auto-Lock

Find and tap on the ‘Auto-Lock’ option within the Display & Brightness settings.
Auto-Lock controls how long your iPhone waits before going into standby mode.

Step 4: Choose ‘Never’

Select ‘Never’ from the list of options to prevent your iPhone from automatically going into standby mode.
By selecting ‘Never,’ your iPhone will stay awake until you manually lock it or it runs out of battery.

After completing these steps, your iPhone 15 will no longer enter standby mode automatically. This means your screen will stay on indefinitely until you press the lock button or your battery dies. Make sure to monitor your battery life closely, as this setting can drain it much faster.

Tips for Managing Standby Mode on iPhone 15

  • Adjust the brightness of your screen to save battery life when standby mode is off.
  • Use Low Power Mode to conserve energy when you’re not actively using your iPhone.
  • Remember to manually lock your iPhone to prevent unauthorized access.
  • Keep an eye on your battery’s health and charge it regularly.
  • Consider using Guided Access if you need your iPhone to stay on for a specific app or task.
