The lithium battery characteristics of the Kindle
1. No memory effect, the battery can be charged at any time, no matter the battery is empty or not.
2. Cannot withstand overcharging. Overcharging is easy to shorten battery life.
3. Can not withstand excessive discharge: over discharge (voltage less than 3.0v), electrode detaching too much lithium ions, resulting in shortened life of Kindle battery.
4. If not used for a long time, it is recommended to keep 40% ~ 60% battery. When the battery power is too low, it may lead to over discharge due to self-discharge. Therefore, it is recommended to charge the unused lithium battery regularly to avoid self-discharge under the minimum working voltage.
Which behaviors consume Kindle battery power?
In fact, it is based on how it works, the Kindle is a very power-efficient device, and its power consumption is mainly concentrated in the following four aspects:
- Turn the page
- The WiFi
- Books Index
- The backlight
So when you don’t need to download an e-book, it’s recommended that you switch to airplane mode, which will greatly increase the Kindle’s battery life.
Besides that, the index is also a great cost of electricity, especially because some ebook file has errors, which makes Kindle fail to index the book, thus Kindle would stuck on the error file and constantly trying to index the file, which causes a death cycle (Kindle boot or standby mode).
This death cycle not only slows down the other processes of Kindle, such as slow page flipping. Index stuck costs more power than turning on WiFi or turning pages.
To avoid the index problem, it is best to:
Keep the e-book format as mobi, azw, azw3, PDF and other formal formats supported by Kindle, don’t sideload downloaded e-books from unknown sources.
Send an e-book or document to the Kindle via email attachment. (You can check the “send to Kindle” service which is provided by Amazon for free)
Do I have to use the original charger?
The charger of Kindle is compatible with the charger of iPhone, Android and other digital devices, you can use any of them.
In addition to the charger, the USB cable is also important. Most of the certificated brands are totally fine to replace the original USB cable
How long and how frequent should I charge a Kindle?
Depending on characters of the lithium-ion battery, we can charge the Kindle at any time. When the Kindle’s battery is less than 20 percent, charging can damage the battery.
In order to extend the battery life, the Kindle needs to be charged when the battery power remains 20%~25%. When the charging indicator light of the Kindle changes from orange to green, the charging should be stopped to prevent overcharging.
Why Kindle battery icon is not full after completion of charging?
Generally speaking, it is advisable to charge a lithium battery to 95%. If the battery continues to be charged, the device will be charged at very weak electricity to compensate for the loss of the battery. The purpose is to protect the device from overcharging. So you needn’t to worry about the battery icon is not displayed as 100%.
However, the latest Kindle firmware has some fixes about the battery icon display.
What are the Kindle charger parameters? Are there any standards?
On the back of the Kindle, you can see: input 5.25V Max 500mA, so it is fine that the charger’s maximum output ampere is greater than or equal to 500mA (less than 500mA will damage the charger).
The Kindle’s charging module automatically controls the amount of charging electricity, so you don’t have to worry about burning out your Kindle device with a non-original charger.
