Kindle Fire Battery Drains When Not In Use (Causes & Solutions)

Have you noticed that your Kindle Fire’s battery drain even when it’s not in use? It can be frustrating, but it’s not entirely abnormal.

Here’s the thing; even when your Kindle Fire is turned off, it’s still using a small amount of power to stay connected to things like WiFi and the Amazon cloud. So over time, this can drain the battery a bit.

If you’re really worried about it, this guide will show you some easy troubleshooting steps you can take to help preserve your kindle fire battery life. But first, you need to understand the battery capacity of your kindle fire battery.

What Is the Battery Capacity of Kindle Fire?

The Kindle Fire has a larger battery capacity than other Amazon Kindle reading devices. But because it performs more tasks than other kindle devices, its battery may not last as much.

According to Amazon, the battery life of the Kindle Fire Tablet is between 7 and 12 hours, depending on the version of the device. However, this recommendation is based only on test conditions and does not reflect real-life situations.

For example, my Kindle Fire HD 10, with a battery capacity of 6300 mAh, usually lasts up to 10 hours when connected to Wi-Fi. Whereas a Kindle Fire 7 Tablet with a battery capacity of 2980 mAh may last up to 6 hours with a Wi-Fi connection.

When these devices are not connected to Wi-Fi or are not in use, the battery should drain at a slower rate. So, if you continue to observe that your Kindle Fire’s battery drains quickly even when not in use, something is using your battery without your knowledge, and you must find a way to control it.

Reasons Why Your Kindle Fire Battery Drains When Not in Use

There are a few possible explanations as to why your amazon kindle tablet battery drains when not in use. Some of these issues are connected to how the tablet manages power, while others may be related to the hardware itself.

1. Kindle Wi-Fi is “ON”

When your Wi-Fi is turned on and connected to the internet, your Kindle Fire device will regularly check for updates and notifications, even when you’re not actively using it. Unfortunately, this can slowly drain your kindle battery over time.

It gets even worse when the Wi-Fi is turned on, but there’s no network to connect to. Your device will simply continue to search for a network, using more battery power until it drains out.

2. Device is Updating

The kindle fire default setting allows the device to update its software system and apps in the background. While this helps keep your Kindle Fire up-to-date and running smoothly, it does drain a significant amount of battery power.

So, if you’re not planning on using your Kindle Fire for a while, it’s best to disconnect it from the internet and preserve your battery life.

3. Apps Running in the Background

Some apps continue to function in the background even when you are not actively using them. Unfortunately, these apps require a high amount of energy to continue running, which not only drains your battery but also slows down your Kindle Fire.

4. Battery Is at the End of Its Life Cycle

Sometimes, it’s not an app or a setting that affects your Kindle Fire battery life but rather the battery itself. Your tablet, like anything else, ages, and over time, the battery loses its full capacity. This results in power draining even when the device is not in use.

5. Kindle Was Used

Funny but true, your Amazon tablet was probably not unused as you thought. Someone in your home, perhaps your partner or kid, may have accessed your device while you were away.

Children enjoy playing games, and your partner may have continued a movie you both started streaming but doesn’t want you to know about it. You should ask them to find out if anyone has used up the battery.

How to Stop Kindle Fire Battery From Drain When Not In Use

These simple Kindle Fire troubleshooting tips will help you conserve your tablet’s battery power when it is not in use.

1. Put Kindle Fire on “Sleep Mode”

The simplest approach to preserve battery power on your Amazon Kindle Fire is to put it in sleep mode when not in use. According to Amazon, Kindle uses almost no battery when in “Sleep Mode”.

To engage the sleep mode, press and release the power button. This will turn off the backlight, and only the screensaver will be on display.

You can also use the sleep timer on your Kindle tablet. This automatically sends your device to “sleep mode” when it is inactive for a set time. I prefer to leave mine at the default setting of five minutes, but you can change yours to a shorter time, perhaps one minute, to save more battery.

To change your tablet’s timeout setting;

  • Go to the “Settings” menu.
  • Choose “Display” or “Display & Sounds”.
  • Then choose “Display Sleep” or “Sleep”.
  • Select the number of seconds or minutes you want your screen to stay on when not in use.
  • When you’re ready to use your tablet again, simply tap the power button to remove sleep mode.

2. Turn Off Wi-Fi

Make it a habit to turn off your Wi-Fi (or Mobile connection) or use airplane mode during the daytime when you don’t need the internet and during sleeping hours or when you are not using your tablet.

To turn off your Device’s Wi-Fi;

  • Go to the Kindle’s menu
  • Click on the Wi-Fi icon
  • And slide the orange icon in the top right corner to switch Wi-Fi on/off.
  • You can also switch the airplane mode on and off on the menu bar.
  • Or use the smart Suspend options in the settings to disable your Wi-Fi and internet connections for a specified period.

These settings ensure that you do not receive any updates or downloads, thus saving battery life.

3. Exit all Apps

Every time you stop using your Kindle Fire, whether after playing a game or watching a movie, make sure to properly exit the apps, so they’re not running in the background when you drop your tablet.

  • To close apps, tap the square icon in the bottom right corner of your home screen to see all the currently active apps. Then, swipe up to close an app or choose “clear all” to close all open apps at once.

However, some apps may not close using this simple method, thus requiring you to force them close.

  • Go to the “Settings” menu on your Kindle home screen.
  • Select Applications > Manage All Applications.
  • Then, select Running Applications.
  • Choose an app to close and press the ”Force Stop” button.
  • Repeat the process for all the apps you want to close.

4. Turn off Notification Settings

Turn off Notification Settings

Apps on your kindle fire “Show notifications.” on default. However, some apps go overboard with these notifications, which can drain your battery faster.

Take a look at which apps are sending you the most notifications. If there are any that you don’t really need to be getting notifications from, turning them off can give your battery a much-needed boost.

  • Go to the Settings menu.
  • Select Sound & Notification > App Notifications.
  • Click on the “Off” button for each app you don’t want to get notifications.

5. Turn off your Kindle Fire

If none of the previous measures is helping the battery performance of your kindle fire as you’d like, I recommend that you switch it off anytime you are not using it. This will preserve the battery’s life until you are ready to use it again.

  • To turn off your Kindle Fire, Press and hold the power button for 10 seconds until the screen goes blank.
  • To restart your device, press the power button again.

6. Replace Your Device’s Battery

No amount of debugging will make your kindle fire battery last if it’s weak or damaged. You may even experience other problems, such as the device charging slowly or not charging at all and displaying a battery error.

To start enjoying good battery life on your kindle fire again, you may have to replace the battery or get a new device.

  • Use the appropriate USB cords and adaptor to charge your device.
