# The Best Color E-Ink Tablet? Boox Note Air 4C REVIEW  ## Intro [(00:00:00)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=0s) - The Boox Note Air 4C is being reviewed to determine if it's the ultimate device that truly does it all [(00:00:02)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=2s). - The Boox Note Air 4C has the same ink technology, display size, and an almost identical design as its predecessor [(00:00:12)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=12s). - The release of the Boox Note Air 4C is a refresh, prompting the question of whether it makes sense to upgrade from the Note Air 3C [(00:00:21)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=21s). ## Design & Build Quality [(00:00:24)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=24s) - The Boox Note Air 4C's design remains largely unchanged from the previous model, which is a good thing, as it still offers one of the best hand feels of any [[Electronic paper | e-ink]] tablet out there [(00:00:24)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=24s). - The grip area is wide enough to offer plenty of support without being too wide, and the edges around the frame are rounded for added comfort during long reading or writing sessions [(00:00:41)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=41s). - The aluminum build is as robust as ever, and the whole tablet feels very sturdy and doesn't creak or crack when applying a little force [(00:00:51)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=51s). - However, the printed Note Air 4C label on the back cover is not as robust and is already coming off with minimal use [(00:01:01)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=61s). - The device is 5.8 mm thick, which may not be as thin as the Boox Nova 10.3, but this difference doesn't matter much in everyday use [(00:01:13)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=73s). - The weight of the device is 420g, which is 20g lighter than its predecessor, and this weight difference is noticeable when holding the device for hours [(00:01:28)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=88s). - The placement of the USB-C connector on the side can be a bit tedious, especially when using a cover, but the improved battery life makes this less of an issue [(00:01:46)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=106s). - The device has a microSD card slot below the USB-C connector, which is useful for expanding the 64GB internal storage, of which only about 37GB is freely available [(00:02:04)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=124s). - The Note Air 4C has a fingerprint reader built into the power button on the top of the device, which is flat and doesn't easily get triggered when changing screen orientation [(00:02:27)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=147s). - The pen magnetically attaches to the side of the tablet, and while the magnetic pole isn't the strongest, it's still fine and didn't cause any issues during everyday use [(00:02:44)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=164s). - The device comes with the Pen Plus, which is the standard stylus, but the reviewer is not a big fan of it due to the cheap feel and missing eraser [(00:03:01)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=181s). - The device has a factory-applied screen protector, which is not scratch-resistant, so it's recommended to get the original case for transporting and storing the device [(00:03:16)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=196s). ## Specs & Android 13 [(00:03:30)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=210s) - The Boox Note Air 4C features 6GB of RAM, an upgrade from the previous 4GB, and a new Snapdragon 690 octacore CPU, which promises a performance increase of up to 20% [(00:03:31)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=211s). - The device's performance increase may not be dramatic in everyday use, as the Note Air 3C chip was already quick for an [[Electronic paper | e-ink]] device, but Geekbench 5 confirms the improvement [(00:03:49)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=229s). - The Boox Note Air 4C runs on [[Android 13]], a newer version than the previous Android 12, making it the first Boox device with this version [(00:03:57)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=237s). - Although Android 13 is not the latest version, it is solid and most apps will support it for a long time [(00:04:08)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=248s). - The device comes with the Android security patch from October 2024, which is a significant update, especially since the tablet can connect to the internet and install apps [(00:04:15)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=255s). - The Boox Note Air 4C allows for app installation through side-loading or directly from the integrated [[Google Play | Google Play Store]], making it easy to install apps [(00:04:37)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=277s). - The device features stereo speakers and a microphone, minimizing limitations when running apps [(00:04:42)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=282s). ## Boox Super Refresh Technology [(00:04:49)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=289s) - Boox Super Refresh Technology, also known as BSR, is a proprietary technology that allows for quicker screen refreshes, making it suitable for running dynamic content on [[Electronic paper | e-ink]] devices [(00:04:51)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=291s). - Normally, e-ink technology is slow and not meant to run dynamic content, but BSR helps to overcome this limitation [(00:05:03)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=303s). - Although the refresh rate of the display is not as quick as an LCD, BSR helps to reduce ghosting and makes it possible to run dynamic apps smoothly [(00:05:13)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=313s). - BSR reduces image quality, so it's not used all the time, and users can manually switch between different refresh modes to find the perfect fit for specific apps [(00:05:27)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=327s). - The technology has a bit of a learning curve, especially when fine-tuning apps with the additional e-ink settings, but it works perfectly well once users get the hang of it [(00:05:37)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=337s). - Most apps work without issues out of the box, without the need to tinker with the settings, and some apps like [[Microsoft OneNote | OneNote]] work without any adaptations [(00:05:44)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=344s). - Even with the [[Electronic paper | e-ink]] screen, [[Android 13 | Android]] on the Boox Note Air 4C offers a lot of versatility and flexibility, making it one of the most important selling points [(00:06:05)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=365s). ## User Interface & Ease of Use [(00:06:14)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=374s) - The Boox Note Air 4C features a newer Android version and a tablet-like UI from the Boox Tab series, which is a welcome change as it is more familiar and flexible for Android users [(00:06:14)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=374s). - Android on the Note Air 4C is heavily customized for the E-Ink screen, making it a different experience compared to regular Android smartphones or tablets [(00:06:30)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=390s). - The device offers a lot of options with settings, which can be overwhelming for first-time users, resulting in a learning curve [(00:06:41)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=401s). - However, once users get accustomed to the device, the system proves to be well-optimized for the [[Electronic paper | E-Ink]] screen, providing a smooth experience for various use cases [(00:06:53)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=413s). ## Color E-Ink Display (Kaleido 3) [(00:07:03)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=423s) - The Boox Note Air 4C features a 10.3-inch color E-Ink screen with Kaleido 3 technology, which is the same as the previous generation but with a few tweaks [(00:07:04)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=424s). - Kaleido 3 uses black and white E-Ink particles to create a reflective, analog paper-like feel, with a color filter on top featuring tiny red, green, and blue sub-pixels [(00:07:13)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=433s). - The display can render up to 4,096 colors, but the colors are more muted, like pastel, and not as vibrant as those on an LCD screen [(00:07:30)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=450s). - The screen's color display comes with some downsides, including the muted colors, which may not meet expectations for those used to an iPad-like experience when viewing comics or other color content [(00:07:50)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=470s). - Another downside is the slight graininess of the screen, resulting from the tiny RGB sub-pixels, which is more noticeable at closer reading distances [(00:08:11)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=491s). - The screen also appears generally darker when not using the front light, due to the translucent and light-absorbing colored sub-pixels, but this can be fixed by turning up the front light [(00:08:30)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=510s). - Despite these limitations, the color [[Electronic paper | E-Ink]] display is still a great feature to have, and some users may quickly get used to the muted look and find it hard to go back to a black and white ink screen [(00:08:02)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=482s). ## Frontlight Improvements [(00:08:44)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=524s) - The Boox Note Air 4C has an average maximum brightness of 69 nits, making it the brightest 10.3-inch e-ink device in its size segment at the moment [(00:08:51)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=531s). - The tablet is roughly 50% brighter than the Note Air 3C, and it also features more uniform brightness [(00:08:56)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=536s). - Although a brightness gradient is still present, it is less noticeable and only slightly visible during everyday use [(00:09:02)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=542s). - The front light of the Boox Note Air 4C can be adjusted in color temperature, allowing for a comfortable warm orange light at night [(00:09:12)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=552s). - The device is one of the most uniform 10.3-inch [[Electronic paper | e-ink]] tablets available, with more vibrant colors when the front light is turned up to the maximum [(00:09:18)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=558s). - Compared to the Note Air 3C, the 4C has slightly better colors in general, and the Vivid mode has a greater impact on color saturation [(00:09:31)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=571s). - However, using Vivid mode comes at the cost of detail, so it depends on the type of content whether it makes sense to use it [(00:09:41)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=581s). ## Side-by-Side Comparison (Boox vs. Remarkable vs. Bigme) [(00:09:48)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=588s) - A side-by-side comparison of the Boox Note Air 4C, [[ReMarkable | Remarkable Paper Pro]], Note Air 3C, T Ultra C Pro, and Bigme 1051 C displays reveals notable differences between them, particularly in terms of brightness, color saturation, and contrast when the frontlights are turned up to maximum setting [(00:09:48)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=588s). - The Boox Note Air 4C outshines the other devices due to its brighter frontlight, better color saturation, and contrast, even surpassing the Remarkable Paper Pro in some instances, except for yellow tones [(00:10:02)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=602s). - The Remarkable Paper Pro's use of yellow E Ink particles makes it more vibrant with yellow color tones, but it also tends to lean towards yellow with green and orange, which may not be accurate [(00:10:22)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=622s). - The Boox Note Air 4C has the best balance among the Kaleido 3 screens in terms of contrast, color saturation, and detail, but a more in-depth comparison is needed to fully evaluate the differences [(00:10:36)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=636s). - A separate video will be created to provide a more in-depth side-by-side comparison of the devices [(00:10:52)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=652s). ## Ghosting [(00:10:58)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=658s) - Ghosting on an [[Electronic paper | E-Ink]] screen refers to the display of a slightly visible after-image of the previous page [(00:10:58)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=658s). - The ghosting effect on the device is largely unchanged from other K3 devices and is heavily dependent on the content, apps, and E-Ink modes and settings used [(00:11:04)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=664s). - Ghosting is more noticeable when viewing image-rich content, and reducing it often requires adjusting the device's settings [(00:11:11)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=671s). ## Pen Latency & Writing Feel [(00:11:17)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=677s) - The Boox Note Air 4C has [[Wacom]] pen support and a pen latency of just under 20 milliseconds, making it one of the fastest e-ink tablets on the market, resulting in a very natural writing feel [(00:11:22)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=682s). - The actual writing feel of moving the pen tip over the surface of the display is similar to that on the Node a 3C but with a bit more friction [(00:11:37)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=697s). - The increased friction is often described as more paper-like, but with the soft work comp pen tip, the writing feel is closer to a felt tip pen than a pencil [(00:11:48)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=708s). - Despite this, the Boox Note Air 4C still results in a good analog writing feel [(00:11:54)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=714s). ## Note Taking App & Table of Contents Feature [(00:11:58)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=718s) - The note-taking app has seen improvements over previous versions, including shortened labels that no longer get cut off by the bezel, offering more refinement than in the past [(00:12:02)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=722s). - The app retains a large number of features, including different pen types, layers, shapes, templates, audio recording, handwriting conversion, and the option to link files, websites, and notebook pages [(00:12:12)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=732s). - A new feature allows users to add an outline to a page, creating a table of contents for a whole notebook, although it's not as convenient as the one on Supernote devices [(00:12:26)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=746s). - The outline feature can be added independently of the page's contents, providing more flexibility and making it a great option for power users [(00:12:44)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=764s). - Selected brush types now have pressure and tilt sensitivity, making the device an interesting choice for sketching [(00:12:52)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=772s). - Notes can be synced with an Onyx account, and users have the option to choose between US, European, and default Boox servers to store their notes [(00:12:58)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=778s). ## Data Privacy [(00:13:07)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=787s) - Onyx has a data privacy policy in place, adhering to the EU's Data Privacy Protection Law, which users must agree to when setting up the tablet [(00:13:07)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=787s). - Despite having a data privacy policy, an option to completely opt out of any tracking is not available, unlike some other e-book devices [(00:13:18)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=798s). - The Boox Note Air 4C occasionally connects to [[Chinese language | Chinese]] servers, even when not using cloud services or having software update checks enabled [(00:13:23)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=803s). - This issue is not unique to Boox devices, as [[Android 13 | Android]] in general can be a "chatty" operating system, communicating with servers even when not necessary [(00:13:34)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=814s). - To address data privacy concerns, it is recommended to use a software firewall [(00:13:41)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=821s). ## PDF Features [(00:13:45)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=825s) - Boox has been the best choice for viewing and annotating PDFs on [[Electronic paper | e-ink]] devices, and this remains true with the Note Air 4C [(00:13:45)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=825s). - The device offers different viewing modes, including a columns mode that zooms in on a portion of the page for better readability of multi-column articles [(00:13:54)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=834s). - The columns mode is particularly useful for reading scientific papers and other documents with multiple columns [(00:14:03)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=843s). - For comics, the "fit to width" option is often sufficient, fitting the page to the width of the display [(00:14:08)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=848s). - If needed, users can also use the pinch-to-zoom gesture, which generally works well on the e-ink screen [(00:14:15)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=855s). - The device allows direct annotation of PDF files without requiring special conversions, and annotated files can be easily transferred to a PC for further work [(00:14:20)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=860s). - A minor issue with palm rejection can be mitigated by temporarily disabling touch input while annotating a page, thanks to the various options available [(00:14:31)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=871s). - Overall, the Note Air 4C offers the best PDF functionality available on [[Electronic paper | e-ink]] devices, thanks in part to its color production capabilities, which are particularly helpful for graphs and images [(00:14:43)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=883s). ## E-Book Features [(00:14:53)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=893s) - The Boox Note Air 4C allows users to read regular ebooks, with its library offering useful filtering and sorting options [(00:14:53)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=893s). - The reading app on the device has essential functions, including multiple options for personalized text styling, taking notes, and looking up words in the dictionary [(00:14:59)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=899s). - The dictionary lookup function uses an online dictionary by default, but users can also use local dictionaries, which they need to load themselves [(00:15:07)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=907s). - The text styling options have been reworked to resemble those of Kindles, allowing users to change the styling and save it as a theme [(00:15:19)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=919s). - Users can quickly switch between different themes, making it convenient to change the text styling [(00:15:28)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=928s). ## Text-To-Speech Demo [(00:15:30)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=930s) - The Boox Note Air 4C has a text-to-speech function that utilizes the default [[Android 13 | Android]] speech synthesis, allowing users to continue reading their book even when they can't look at the screen [(00:15:30)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=930s). - This feature can also be helpful for learning how to read, and users can download different voices, languages, and dialects to customize their experience [(00:15:48)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=948s). - A demonstration of the text-to-speech function is provided, reading a passage from a book about the characters Bingley and Darcy, showcasing the feature's ability to read aloud with a synthesized voice [(00:15:52)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=952s). - The passage describes the friendship between Bingley and Darcy, highlighting their contrasting personalities and how they complement each other, with Bingley being more open and Darcy being more reserved and clever [(00:15:54)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=954s). - The text-to-speech function reads the passage with a synthesized voice, demonstrating its ability to convey the story and characters, although it may not sound as good as a professionally recorded audiobook [(00:15:36)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=936s). ## Battery Life [(00:16:47)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1007s) - The battery life of the Boox Note Air 4C is an interesting topic, especially when compared to its predecessor, the Note Air 3C, which initially had poor battery life of around 8 hours for reading with maximum screen brightness [(00:16:47)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1007s). - After retesting the Note Air 3C with updated software, its battery life improved to around 2% drain per hour with the screen on and the front light turned off, making it slightly better than the Note Air 4C in this scenario [(00:17:36)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1056s). - The Note Air 4C's battery life is around 2.5% drain per hour with the screen on and the front light turned off, which is much better than its initial performance [(00:17:30)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1050s). - With the front light turned on to 30 nits, the Note Air 4C's battery life is around 4% drain per hour, resulting in a total run time of around 25 hours [(00:18:20)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1100s). - At full front light brightness, the Note Air 4C's battery life is around 9.5% drain per hour, resulting in a total run time of around 10 hours [(00:18:30)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1110s). - The Note Air 3C's battery life also improved significantly with the front light at full brightness, from 13.3% drain per hour initially to around 8% per hour after the software update [(00:18:41)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1121s). - The Note Air 4C's front light is 50% brighter than the Note Air 3C, so when matching front light brightness, the battery performance of both models is similar [(00:18:55)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1135s). - Battery life on an [[Android 13 | Android]] [[Electronic paper | e-ink]] tablet with stylus support depends heavily on the device's usage, with reading being the most battery-friendly activity and watching [[YouTube]] videos in Ultra fast mode with full front light brightness being one of the worst, resulting in a battery life of around 4.5 hours [(00:19:28)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1168s). - When writing with the pen and not using the front light, the Note Air 4C's battery life is around 10 hours, which decreases as the front light brightness increases [(00:19:46)](https://www.youtube.com/watch?v=yjsjBM5j7Mg&t=1186s). -
