How to Check What Software Your Kindle Has
Your Kindle should download and update itself automatically when charged and connected to Wi-Fi. However, if you want to leave your Kindle in airplane mode, haven’t connected it to the internet in a while, or have it charged recently, your Kindle may not be running the latest software.
To see which version of your Kindle software is currently running, go to your Kindle home page and tap the three small dots in the top right corner to open the menu.
Tap Settings in your Kindle’s menu.
Tap “Device Options” on the Settings screen.
Tap Device Info to see information about your Kindle’s hardware and firmware, the software that runs on it.
Under ‘Firmware version’ you can see the release your Kindle is running on. In the screenshot below, you can see mine is on Kindle 5.13.5.
Once you know what software your Kindle has, it’s time to compare it to the official release list. Visit the Amazon Kindle Software Updates page. Find your Kindle version and compare the number with the last released version.
I have a Kindle Paperwhite (10th generation) so mine is completely up to date.
Update your Kindle over Wi-Fi
If your Kindle doesn’t have the latest software installed, you can update it. First, connect your Kindle to WiFi and plug it in to charge.
On your Kindle’s Settings screen, tap the three small dots.
If ‘Update Your Kindle’ is black, tap it to update your Kindle. If it is grayed out, it means your Kindle is up to date or an update is otherwise unavailable.
How to Update Your Kindle Manually
If your Kindle refuses to update to the latest version over Wi-Fi, you can manually install the software update.
To do this, you need to download the latest Kindle firmware version from Amazon and transfer it to your Kindle with your computer.
