Disable Background App Refresh

Are you constantly finding yourself running out of battery on your iPhone? One of the reasons could be the background app refresh feature. This feature allows apps to continue updating and refreshing their content even when you’re not actively using them, which can drain your battery quickly. However, you can take control of your battery life by disabling the background app refresh feature.

To disable background app refresh, simply follow these steps:

  1. Go to the “Settings” app on your iPhone.
  2. Scroll down and tap on “General”.
  3. Find and tap on “Background App Refresh”.
  4. Here, you will see a list of all the apps that have background app refresh enabled.
  5. To disable background app refresh for all apps, toggle the switch at the top of the screen to the off position.
  6. If you want to disable background app refresh for specific apps only, you can manually toggle the switch next to each app.
  7. Once you’ve made your desired changes, exit the settings app.

By disabling the background app refresh feature, you will not only extend your iPhone’s battery life but also potentially improve its overall performance. Keep in mind that some apps may require background app refresh to function properly, so disabling it for all apps might affect certain functionalities. Therefore, it’s recommended to disable background app refresh only for apps that you don’t frequently use.

Take control of your iPhone’s battery life and put an end to constantly running out of battery. Disable the background app refresh feature and enjoy longer usage times on your device.

Turn on Hi-Brightness Display

One effective way to drain your iPhone battery quickly is by turning on the high-brightness display. While smartphones nowadays come with automatic brightness adjustments for optimal viewing and power consumption, manually setting the display to its highest brightness level can significantly drain the battery.

The bright and vibrant display not only enhances the visual experience but also consumes more power. So, if you’re looking to quickly drain your iPhone battery, this is a simple but effective method.

To turn on the high brightness display on your iPhone, follow these steps:

  1. Unlock your iPhone and access the Settings app.
  2. Scroll down and tap on “Display & Brightness.”
  3. Under the “Brightness” section, drag the slider to the maximum level.
  4. Exit the Settings app, and you’ll notice that the display is now much brighter.

However, it’s worth noting that using the high-brightness display for prolonged periods can put strain on your eyes and may reduce the battery lifespan in the long run. It’s best to use this method sparingly and only when you specifically want to drain your iPhone battery quickly.

Remember to adjust the brightness back to the optimal level when you’re done, as this will help conserve the battery life and ensure better visibility in regular usage scenarios.

Enable Push Email Fetch

Your email inbox is an essential part of staying connected, but constant email notifications can drain your iPhone battery quickly. By enabling Push Email Fetch, you can have more control over when your device fetches new email messages, conserving battery life in the process.

Push Email Fetch is a feature that allows your iPhone to automatically retrieve new emails as soon as they arrive in your inbox. While this can be convenient, it can also be a drain on your battery life, especially if you have multiple email accounts or receive a high volume of emails.

To enable Push Email Fetch, follow these simple steps:

  1. Open the “Settings” app on your iPhone.
  2. Scroll down and tap on “Mail.”
  3. Tap on “Accounts,” then select the email account you want to modify.
  4. Tap on “Fetch New Data.”
  5. Toggle the “Push” option to “Off.”
  6. Under the “Fetch” section, you can choose between different intervals for checking new emails – every 15 minutes, every 30 minutes, hourly, or manually.
  7. Select the desired interval that suits your needs. Keep in mind that selecting a longer interval will help conserve battery life.

By disabling Push Email Fetch and opting for longer intervals between email checks, you can significantly extend your iPhone’s battery life. However, keep in mind that this means you might not receive email notifications as promptly as you would with Push enabled.

If you want to check your emails more frequently, you can always manually fetch new emails by opening the Mail app and pulling down on the screen to initiate a refresh. This way, you have more control over when your device consumes battery power to fetch new emails.

Remember, enabling Push Email Fetch may not make a drastic difference in your battery life if you only have one email account or receive minimal emails throughout the day. However, for heavy email users or those wanting to optimize their battery usage, enabling a longer fetch interval or even disabling Push altogether can be a worthy consideration.

Use Battery-Intensive Apps

One surefire way to drain your iPhone battery fast is by using battery-intensive apps. These are applications that require significant processing power, graphics capabilities, or internet connectivity, which in turn, put a heavy strain on your device’s battery.

Examples of battery-intensive apps include video streaming services like Netflix and YouTube, graphic-intensive games like Fortnite or PUBG, and GPS navigation apps like Google Maps or Waze.

When you launch these apps, your iPhone needs to work harder to deliver a smooth and seamless experience. This increased workload translates to more power consumption, ultimately draining your battery at a faster rate.

If you’re looking to drain your iPhone battery quickly for a specific purpose, like testing battery life or performance, using battery-intensive apps is an effective method.

Remember to keep your device plugged in or have a power bank nearby, as using these apps extensively can lead to your iPhone’s battery levels plummeting rapidly. Recharge your device promptly to avoid running out of power unexpectedly.


In conclusion, knowing how to drain your iPhone battery fast can be helpful in certain situations. Whether you need to test the battery life of your device, calibrate the battery, or simply want to conserve power when you’re not using your phone, these methods can come in handy. However, it’s important to note that regularly draining your iPhone’s battery can have adverse effects on its overall lifespan and performance.

While it’s important to be familiar with these techniques, it’s equally important to use them sparingly and in moderation to avoid any potential damage. Remember to always charge your iPhone using a reputable charger and keep an eye on your battery health to ensure optimal performance. By implementing these strategies responsibly, you’ll be able to make the most out of your iPhone’s battery and enjoy its features for a long time.
