Amazon Launches Enhanced Kindle Colorsoft Signature Edition 2025

Amazon has unveiled the revised Kindle Colorsoft Signature Edition, which features significant enhancements and 32GB of storage. Launched in July 2025, this updated model boasts a superior display and improved performance, addressing issues found in the previous version released in 2024.

The most notable upgrade is the new 7-inch E Ink Kaleido 3 color e-paper display. This advancement dramatically improves the reading experience with a grey background and deep black text. The updated screen effectively resolves the yellow band issues that affected the earlier model, making it comparable to the monochrome displays of the standard Kindle and Kindle Paperwhite. Alongside the display, Amazon has implemented a different mainboard, enhancing the device’s processing power and responsiveness when navigating e-books or the user interface.

The Kindle Colorsoft Signature Edition 2025 features a redesigned internal structure, including repositioned charging coils and updated FCC and model identification on the back plate. This edition contains 28% recycled materials, a significant increase from the 18% used in its predecessor, contributing to a more environmentally friendly product. Additionally, the new model is 1 gram lighter, reflecting Amazon’s commitment to sustainability while maintaining performance.

Improved Functionality and User Experience

Amazon is gradually rolling out the 2025 Colorsoft model in various regions, with initial availability in Europe and Japan. To identify whether you are purchasing the 2024 or 2025 edition, check for a UPC that ends in 7439 and a DSN that includes H7035. The updated model also comes with a distinctive Amazon listing stating, “All New Amazon Kindle Colorsoft Signature Edition 32GB.”

The technical specifications of the Kindle Colorsoft Signature Edition 2025 include a black and white resolution of 1264×1680 at 300 PPI and a color resolution of 150. The Kaleido 3 screen can display over 4,096 colors and utilizes new coatings and optical performance enhancements for sharper contrast. While the exact processor specifications remain unclear, the 2024 model was equipped with a 2GHz Mediatek processor, 1GB of RAM, and Bluetooth 5.1 capabilities for audiobooks.

The device is rated IPX8, meaning it can withstand immersion in freshwater up to 2 meters for a duration of up to 60 minutes. It also supports quick charging through a USB-C port and is powered by a 2310 mAh battery, which is expected to last approximately eight weeks on light usage.

Software Features and Market Impact

Amazon continues to utilize Linux as the operating system for the Kindle, enhancing battery efficiency by minimizing background processes. Regular software updates introduce new features, such as the recently added “Spacing” settings, allowing users to customize paragraph, word, and character spacing. This flexibility enhances the reading experience for both Amazon-purchased and sideloaded e-books.

The Kindle Colorsoft offers access to the extensive Amazon bookstore, which dominates the e-book market with an estimated 80% share in the USA and 85% in the UK. The platform supports various formats, including Kindle Format 8 (AZW3) and Audible audio formats. Amazon Direct Publishing allows authors to self-publish, further expanding the selection available to readers.

One of the key advantages of the Kindle Colorsoft is its integration with Audible, enabling users to listen to audiobooks through Bluetooth-enabled devices. This feature has been refined over several generations, providing a seamless experience for audiobook enthusiasts.

In summary, the Kindle Colorsoft Signature Edition 2025 presents meaningful advancements in both functionality and user experience. While the updates may seem modest, they collectively enhance the overall reading experience, reinforcing Amazon’s position as a leader in the e-reader market. The device, now equipped with improved technology and sustainability features, caters to the evolving needs of modern readers.
