Reasons Why Your Kindle Battery Drains Fast

Below are some key reasons why your Kindle might be losing power fast. Some facts will surprise you, while others are familiar to you.

1. The Kindle is ever Online

The internet is excellent, and everyone loves it. Modern smartphones have batteries to keep them online for very few minutes.

However, the case is different for Kindle phones. Some models, like the Paperwhite, have a battery range of 1750 mAh.

Connecting the device to Wi-Fi every hour kills the battery. Your Kindle will do many activities in the background besides downloading books. The battery life will drain because of this stress.

It will be worse if your Wi-Fi is on, but the network isn’t in range or weak. The Kindle will use more battery power to search for the perfect network.

2. Too much Brightness

Your screen brightness shouldn’t be something to admire. Too much of it is terrible for your eyes and Kindle battery.

It comes because you have set it at full brightness. The action is more like lighting a room. So, expect it to use more battery power.

You’ll have to recharge it many times a day. Remember, this move reduces your battery life.

 3. e-Book Indexing Error

After your Kindle completes a download, it indexes the book. Here, the phone will arrange your library in the proper order. So, finding books and content becomes easy because of indexing.

But if there is an indexing mistake, the burden falls on your battery. Your battery will keep draining faster.

So, how will you know if your Kindle has an indexing error? Go to the search bar on the home page, type any letters (not a word), and search.

An error will occur if you see the notification “the following books couldn’t be searched because they haven’t been indexed yet.”

4. It’s Time for an Update!

Kindle software updates are essential. But as you get new and unique features, the burden is on your battery.

Unless you change the settings, the device downloads the update when on a stable network. These updates are never small in size.

Once the download is complete, the Kindle will run as you enjoy reading your favorite book. Later on, the system will complete the update.

These steps take a lot of battery power. You can’t update your Kindle while your battery is low.

After the update, your kindle battery should go back to normal. If it keeps draining, there are more problems behind your battery draining.

5. Several Downloads

As a reader, once you connect your Kindle to Wi-Fi, it will tempt you to download many books. It’s risky because your device will use more data and power.

Kindle will need to index them after downloading. These moves take up a lot of power from the battery. If you download many books every day, expect your battery’s range to reduce faster.

Charge your phone after carrying out several downloads. Also, you can disconnect it from the internet and leave it to charge once you complete the downloading.

Such an act replaces the power your battery needs for indexing. So it won’t lose energy fast.

6. Kindle Case or Cover

Your Kindle needs to rest after you use it. But that won’t happen if you place a cover or case on the device.

The tools help protect your Kindle from losing its outer beauty. Also, when you drop the Kindle to the ground, it’s not easy for the screen to break.

These gains are excellent until your battery begins to lose power fast. Covers and cases never let your Kindle sleep.

You’ll see it when you keep a Kindle with a case in your bag. The case will make the Kindle’s sensors turn the phone on every moment.

Besides, the case makes your phone heat up, especially if you live in hot areas. It then becomes a threat to the battery life.

7. Do You Overuse Your Kindle Every Day?

Like any other modern gadget, overusing the Kindle every day kills the battery. Such an event happens while you are traveling, if the book is fantastic, or when you are bored.

As you enjoy the flow of the books, you won’t realize the stress you are giving your battery. If it happens every day, you’ll have to stay close to your charger.

Your battery will be losing power more than you expect. So, if you love reading for many hours, your Kindle battery is bound to die.

Sometimes, you might think your Kindle system has a problem. But no, you must change your reading habits to save your battery.

8. Kindle Clock Display App

The latest update on Kindle devices has a clock on display. It’s a great new aspect that lets you have the clock icon on the lock screen.

This beautiful feature lets you check the time on the device without unlocking it. But on the other hand, it reduces your battery performance.

Yes, the clock app might seem like a minor aspect. But try to uninstall it and see how your battery’s performance will grow.

9. You have a Spoiled Kindle Battery

Though it can become hard to realize, the battery might be draining because it is almost dead. It should be your last thought after you’ve checked the above issues.

Remember, replacing your dead battery is the best way to fix it. But smile because you can replace a Kindle battery.

How to Save Battery Power on a Kindle?

If your Kindle battery isn’t dead, you can make it last for a longer time. Here are the five best tips to increase the battery’s life.

1. Turn the Device Offline

Use airplane mode to disconnect your phone from any network. Go to the Kindle’s menu, and select airplane mode on or off.

Remember, this tip comes at a heavy price. So, you won’t get any updates or downloads. But it helps conserve your battery.

2. Reduce the Brightness Level

Before worry takes away your sweet reading times, consider reducing its brightness levels. Go to your home screen, swipe down, and you’ll see the brightness line. Then reduce the brightness level.

Also, while reading, tap on the top part of your screen. Then adjust it to a lower level. Your battery will operate well as you read.

3. Reboot Your Kindle

Sometimes, your Kindle operating system might be having some issues. These errors make your Kindle battery go down fast.

So, rebooting the device helps it start everything afresh. You’ll notice that the draining has reduced.

Remember, it’s only a temporary fix. If the battery issue persists, please use the other tricks.

4. Use the Sleep Mode

The Kindle is best for reading books. So, if you aren’t ready, put your phone in sleep mode or Kindle power saving mode.

It prevents the device from using any battery power. Even when you start the phone, it will still pick up from where it left off without consuming much power.

5. Expose the battery to the Correct temperatures

Placing or using your Kindle in high temperatures kills your battery. Also, cold temperatures make your phone drain power fast. Keep or use your phone in places with a temperature of between 5 and 20 degrees Celsius.

6. Have Proper Charging habits

Most people kill their phone batteries through bad charging norms. It would be best if you never left your Kindle to have a zero charge.

Sometimes you can avoid it. But if it happens every moment, it harms your battery.

Your charge should be between 20% and 80%. It should also have a 100% charge a few times a year.

While charging, use proper USB cables and adaptors. The unofficial charger may power-up your battery but will reduce the battery life after long-term use.

7. Have a Proper Reading Discipline

This tip solves your problem of being addicted to your Kindle. Spending more hours reading on your Kindle burdens the battery.

Learn to be busy and create other habits besides reading. Though it’s not easy, the trick will give your batteries more years.
