How to Drain iPhone Battery Fast

Two things consume the iPhone battery the most: screen usage and cellular service. If you find yourself in a situation where you need to drain your iPhone’s battery, at least you know where to start. 

This isn’t recommended, though, so try to avoid draining your iPhone battery frequently because the repercussions may be irreversible.

However, if you have a valid reason for it, keep reading to know how to drain the iPhone battery fast.

Tips on How to Drain iPhone Battery Fast

Now that you know the top two culprits that eat up an iPhone’s battery, it’s time for the step-by-step process.

Adjust the Screen Brightness

Keep your iPhone awake and at its brightest by following these steps:

  1. On your iPhone, open Settings.
  2. Select  Auto-Lock under the Display & Brightness tab.
  3. Among the options, tap Never.
  4. Under the Display & Settings tab, tap Auto-Brightness to turn it off.
  5. Adjust the brightness slider to its maximum setting.

This will refrain your iPhone from going to Sleep mode unless you press the side button and lock it manually.

Run Some Battery-Hungry Operations

What do we mean by battery-hungry operations? These are processes that strain the battery, like searching for devices or connections.

Here are a few examples:

  • WiFi searching for a secure or familiar network
  • Bluetooth searching for devices to pair with
  • Cellular service trying for a signal (in locations where the signal is poor)

Ask to Join Networks

So, to drain your iPhone battery using WiFi here’s what you do:

  1. On your iPhone, go to Settings.
  2. Select WiFi and turn it on.
  3. Select Ask to Join Networks and turn this on as well.

Push Notification

The Push Notification feature synchronizes your iPhone to your computer and sends information as often as you wish. The most frequent option is every fifteen minutes, so use this to use as much battery as possible.

Here’s how to do it:

  1. On your iPhone, select Mail, Contacts, and Calendars.
  2. Select Fetch New Data.
  3. Tap Push to turn it on.
  4. Select Every 15 Minutes among the options under the Fetch tab.

Play Online Games Using Cellular

This method is only for those who are willing to spend cellular data. It can be strange to waste data just to drain the iPhone battery all at once, but it’s highly effective actually.

As the heading suggests, simply play your favorite online game using cellular data and you’ll use up your phone’s battery in no time. For good measure, turn on the Bluetooth app and scan for devices while you’re at it.

Again, we don’t recommend this because your phone will definitely heat up in the process.

Other Methods That Drain Battery Faster

Here are a few other ways to use up your phone’s battery fast.

Watch Videos

With the screen at its brightest and cellular data on—if you can afford it, of course; play a series of YouTube videos or a 4K movie. Now, you don’t need to watch it, just auto-play the videos and leave your iPhone.

If you’re going to watch videos while your screen brightness is at its maximum level, it could damage your eyes as well.

Turn On All Notifications

Nothing helps the battery drain faster than a barrage of notifications every few minutes. To do this, here’s the procedure:

  1. On your iPhone, go to Settings
  2. Select Notifications.
  3. Tap Show on the Lock Screen to turn this feature on.

The Repercussions of Draining the iPhone Battery

There will be instances where your phone runs out of battery and your charger isn’t nearby. This is totally forgivable and the damage wouldn’t be significant if this happens once in a while.

Besides, most phones nowadays are the lithium-ion kind, so they’re much more tolerant to such occurrences than the older battery models. Additionally, smartphones are now equipped with software that regulates energy flow during charging sessions.

In other words, draining the battery is generally okay when it happens once in a few months, just don’t make a habit out of it or do it on purpose.

To be safe, heed your iPhone’s warning, that’s when the battery icon turns red. At this point, it’s telling the user that it needs to be charged now.

Moreover, overcharging is equally damaging as draining the battery. Phone manufacturers have different information regarding the ideal battery percentage, but it should be between 20% to 80%.
