Drain the battery on your Android device purposely? This may sound strange, but there are some situations that warrant draining the battery on your device purposely. You may want to store a device for a long period of time, or maybe you want to know how long it takes the battery to charge.

However, completely discharging a Lithium ion battery is bad for it. You should only discharge the battery down to anywhere between 40% and 70% before recharging it. Try to prevent the battery from getting below 20%, except in rare circumstances.

Today we’ll show you an app that will drain the battery automatically and faster than normal. But, first, we’ll show ways to drain the battery on your Android device manually, without an installing an app.

Drain The Battery Manually

There several ways to drain your battery manually without installing an app.

Open Most Of Or All Your Apps

Open most of or all your apps and leave them running. This will drain the battery quickly, especially if you have a lot of apps.

Keep The Screen Awake

If you phone allows you to, set the screen to never go off in the lock screen settings. This will drain the battery faster. If your phone doesn’t have an option to leave the screen on indefinitely, use the Smart Lock feature, when you’re in trusted situations.

Change Your Screen’s Brightness to Maximum

To drain the battery faster, change your screen’s brightness to maximum. Go to “Settings” > “Display” > “Brightness level” (or “Brightness“). You’ll have to turn off “Adaptive brightness” or “Auto brightness” to turn up the brightness all the way.

Drain The Battery Automatically & Faster Than Normal

Fast Discharge is a free app that discharges your device’s battery faster than with normal use, and without requiring you to interact with the device.

After installing Fast Discharge from the Play Store, the “Battery power” at the top of the screen shows the current battery level. The “Goals battery” percentage shows the percentage you want the battery to discharge to. Use the slider to change this value.

Below the slider, select the methods you want to use to discharge the battery. The more methods you select, the faster the battery will discharge. The “Operated vibrator” may be too noisy for your tastes.

To start the discharge process, tap “Discharge inception“.
