How to Drain iPhone Battery Fast: Quick Tips for Power Users

So, you want to drain your iPhone battery fast? Whether you’re trying to calibrate the battery, testing its health, or just curious, there are a few ways to do it quickly. Keep reading, and you’ll learn how to drain that battery faster than you can say "low power mode."

How to Drain iPhone Battery Fast Tutorial

Before we dive into the step-by-step guide, let’s talk about why you might want to drain your iPhone battery quickly. Maybe you’re about to replace your battery and need to discharge it first, or you’re trying to recalibrate the battery life indicator. Whatever the reason, the following steps will help you achieve your goal.

Step 1: Turn off Low Power Mode

To drain your battery quickly, make sure Low Power Mode is turned off.

When Low Power Mode is on, your iPhone reduces background activity like downloads and mail fetch to save battery life. Turning it off will ensure that your phone uses maximum power.

Step 2: Increase Screen Brightness

Crank up the brightness to the maximum level.

The display is one of the biggest power drains on your iPhone. By turning up the brightness, you’re forcing it to use more power, which will drain your battery faster.

Step 3: Turn on Background App Refresh

Go to your settings and enable Background App Refresh for all apps.

This allows apps to check for updates and new content in the background, which uses more battery. With Background App Refresh on, your phone works harder, using more power.

Step 4: Play Videos or Music

Start playing videos or music on your iPhone.

Multimedia content, especially streaming video, can chew through battery life. By continuously playing videos or music, you’re giving your battery a workout.

Step 5: Use Power-Hungry Apps

Open and use apps that are known to consume a lot of battery.

Games, social media apps, or navigation apps are known to drain the battery quickly. Use them actively, and you’ll see your battery percentage drop.

After you complete these steps, your iPhone battery should drain significantly faster than it normally would. Just keep an eye on it, so it doesn’t drain completely if you don’t intend to let it die.

Tips for Draining iPhone Battery Fast

  • Avoid charging your phone while you’re trying to drain the battery.
  • Turn off battery saving features, like Auto-Lock and Reduce Motion.
  • Keep your phone at a comfortable temperature; extreme temperatures can affect battery life.
  • Don’t close your apps; let them run in the background for more power usage.
  • Use Wi-Fi instead of cellular data; it uses more battery power.
