Boox Tab Ultra C Pro: In-Depth Review. The Fastest Colour E-Ink Android 12 Tablet, But at What Cost?

[@omarvillasana]

Excellent video as always, but despite the awful battery life I guess we loose track of what is the most important issue about using an e-ink device, and that is eye strain, so for the use case of people that work long hours in front of the screen that relief might be enough to sacrifice poor battery performance. Thanks again for the great work.

[@cameroncz3197]

That is the main reason I bought Tab Ultra C Pro. I wanted to use it as a tablet (for note-taking I have reMarkable 2) for my studies. Just unboxing it and checking what this device is. I don't want regular tablet or laptop simply for their screen because my eyes are more sensitive to that stuff and it fatigue them quite a lot. It also have something to do with how the OLED and LCD feels to you and your brain or health. I think it has some negative aspect in it.

[@whitestoat]

Agree. Have been using it for my master study. It's an excellent device for reading and marking lecture slides, reading reference books, plus taking notes with Obsidian. Most of the time I am using it in front of my desk with it plugged in to a power source, so battery life is not my concern.

[@abredolflincler1423]

@@whitestoatdoes it really cause no eye strain? I want to get one just because of that. But I’ve seen videos where people argue that e ink screens cause eye strain just like normal screens

[@rikaze]

@@abredolflincler1423 I suspect there be different causes of eye strain/types of strain? For example even reading a regular paper book in low light conditions causes eye strain. I think people who get eye strain from screen light are the ones who benefit from eink tablets? Or in my case, I've started developing motion sickness from any kind of moving lights (screens, light from discoballs), so I can stare at an e ink screen all day, but can't stand looking at my phone for more than a few minutes.

[@jarrettheredia]

Just a note on your battery life comparison between your phone and the Tab C Pro; the power required to full switch pixels in an eink screen can be from 1 to 8 mJ/cm whereas on an LCD screen it's 1/10 of that. The usual battery benefit from an eink screen is that it only uses power when it changes whereas an LCD uses power as long as it's displaying something. However, when watching dynamic content that's constantly changing an eink screen will use far more energy than an LCD screen because it's constantly doing a full switch of pixels and doing a full switch takes more power for eink. Add to that the fact that the screen on the Boox has far more square cm to switch than the screen on your phone, and it's easy to see why you were getting more battery life from your phone than the Boox when watching a video. It's an eink problem, not necessarily a Boox problem. I am grateful for the time and effort you put into your videos! Looking forward to your deep guide on 3.5 update!

[@5idi]

Yes, if he did the reading test on the phone, it could die before the tab, although I've seen some phones get 7 to 10 hours of screen-on time in reviews (depending on use, but with actually using the phone, not just viewing one document without touching the screen) so... go figure. I'm curious. Kind of suspect that in dark mode the phone has a winning chance! Also, the pixel density on the phone is much higher so it consumes more energy per inch. I'd bet the backlight of the tab is more efficient too, but not an expert. Interesting point.

[@MyDeepGuide]

Yes, this is all correct, and precisely because of the refresh protocol differences between panels, the only test that would give a point of comparison is the one that will force an e-ink panel in a constant state of refresh, like a regular display functions. And that happens to be video playback. Hence, the test :)

Great review thanks. I would disagree on one thing, you said, "the one thing you want from an e-ink tab is battery life" yeah that's great but I think for many people it's relief from eye-strain we are looking for.

[@PACotnoir1]

Nice presentation of the Tab Ultra C Pro as usual made by Voja. I own a Tab Ultra C since last spring, his video convinces me not to upgrade for three reasons: as I have near two thousand digital books and papers, in last march, I already needed a larger amount of memory space than on my old NoteAir. With Tab Ultra C. I have now 128 GB of storage space + SD card reader up to 2 TB like on the TUC Pro; battery of the TUC is better with 6300 mAh than on the TUC Pro, that gives me a very good battery life; the colour screen is important for me when I read colour graphics. So as Voja had said, since it's a product in an evolution curve, the improvement is not sufficiently great to change right now. But I agree that the NoteAir3 C, is a great product and maybe I would have bought it if it has been released 7 months ago... Indeed with its 128 GB of memory instead of 64 GB for the NoteAir3 C, the TUC would still stand last spring has a good alternative.

[@skipper63400]

Same here, I wanted to write that if the NA3C was available last spring I would have preferred it to the TUC. But now owning the TUC I see no reason to sacrifice battery life by switching to the latest models. I will stick with my TUC till they improve the screen technology.

Excellent video like all your work. Thank you. You have helped me much to make right choice for me.

[@lmva23]

You may not think that the camera belongs to this device, but in my opinion, you could have made an example of taking a photo and add it on a note, and show the way you can write on top of it, make markings, crops, etc. When producing a report that may need to add photos to increase its details, the camera is something that is very important, and adds a lot of value to these types of documents. Just an opinion. But very good review overall!

[@rafalreloaded]

Finally a Tab Ultra that performs. Great choice with the CPU. It does seem like an unfinished product - the battery drain has to be fixed! I'm waiting for the next version, and hoping they will remove that camera bump.

[@TrTai]

Pure features the tab ultra C pro is awesome, it seems to handle a few things I want to do seemingly better than the NAC3 (mostly reading, annotating, drafting, etc) but I would like to be able to do some applications that I know will run on the 855 versus wondering how much I'm giving up with the 665. I'm mostly IT and programming and most of the heavy lifting will be done on another device but being able to have a smooth connection would be all but guaranteed on the Ultra Tab, but at that price point it costs more than my phone that I do try to do everything on. (S23) I don't expect it to do everything with the product it is, but it makes the price point a lot harder to swallow if you don't know for sure you need the extra oomph. I think this will be the push to go for the Air C 3 and just try and do all I can on it and go from there. If the tab and the keyboard together were at the Tab Ultra C's 650 USD price point (or to push my luck, 550-600), it would be a no brainer I think for anyone looking for the versatility and productivity.

[@Ouswn01]

I had Boox Tab Ultra (BW) and love the device, crisp naturally lit screen with battery life of 5-7 days of propped use (24 hours) I got the tab ultra pro c and for similar use battery is sufficient for a workday (8-10 hours) for such devices, I don’t think battery should be compromised in that manner… the color screen is much darker than the BW which is reasonable at this stage on boox and similar devices… other than that it is a device I enjoy a lot for writing and reading compared to iPads

[@krzysamm7095]

It would be nice if they designed it where you could upgrade android when a newer version comes out

[@ProfessorFutura-ms9fi]

Thank you, Voja. Excellent review again. And finally you commented on reading comics. But did you try reading in Regal mode? (with animation filter time set to 400 at least) It gives you perfect colours without any ghosting, but at the cost of speed. Balanced mode in my opinion has still plenty of ghosting, especially if the comic uses a lot of dark colours. Btw one day I would like you to explain, why you hate OneNote so much. I think Boox makes an excellent job, implementing it in their system. Meanwhile it's really usable. And a lot of people use OneNote, so I think that's a big pro for Boox devices.

[@Ghost-Ghost-Ghost]

Great video! Disagree on the focus on battery life, since e-ink is mostly to reduce eye strain for me, and the keyboard is a huge selling point (I use my ReMarkable 2 keyboard almost every day). Leaning towards this device after watching 4 or 5 of your reviews. Thanks for all the details!

[@flavioortolano]

Hi Voji, I want to ask you advide - I have the NA3C for less than a month and I love it. However as I need to have 2 to 3 very large college ebooks opened plus the note writing app, I found the device gets quite slow and sluggish. I used the cpu-z app to understand how much ram it was using with those apps and e-books loaded in memory and out of the 4gb I had only 0.8gb left of available ram; so me not being an expert in hardware/system performance, I inferred low ram being the main issue for the slowness. Hence, I am willing to return my na3c and get the tab ultra c pro assuming the performance would improve for my use case by having the extra 2gb ram and slight faster processor. Here is my question: how bad is it to take notes on the TUC pro on a flat surface without a case? I know it sounds crazy but I must use the device without a case/cover (medical/physical limiation reasons). But having read about the wobbling created by the camera bump, I wonder how bad this really is? Can you simply get used to taking notes with the wobbling or is it just too annoying and distracting, cumbersome to the point where the only alternative is to have a cover? Can the wobbling be overcome by simply getting used to it or another workaround, or is the design makes writing on a flat surface simply impractical? My iPad has a camera and it’s about +-2.5mm high and it’s not all that bad to write on it, but TUC pro camera bump looks more like 5-6mm?? I was hoping you could provide your take on this since in more detail. You did mention briefly about the wobbling in one of your videos, but didn't go into much detail, and I was hoping you could give me your advice as to whether the camera bump is really a deal-breaker for those wanting to use it without a case/cover. I would appreciate your honest perspective and insight on this as it would help me make an educated decision. Thanks for the great work and amazing content produced.

[@TechforRealLife]

Love the review. Really helps me way the pros and cons! You cannot get your tutorial on 3.5 done fast enough! I use my NA3C everyday at work and I would really like to know I am doing things efficiently and effectively. Also, question: now that the NA3C is out, is your Supernote still your daily driver?

[@MyDeepGuide]

I use them both. Supernote for work related designing and writing, where I need the Titles and the intricate linking functionality, and also, just the raw stability and confidence of the Supernote as a system. NA3C is for everything else that is not Computer related, including journaling, etc.

[@TechforRealLife]

@@MyDeepGuide Thank goodness! That was actually what I was hoping you would say. I thought I might be a bit nuts because I actually have the need for more than one device because I have multiple needs when it comes to applying eink technology to my life and my career. That’s incredibly helpful Voja. Really, thank you!

[@Kamadev888]

@My Deep Guide - Voja, which one has better battery life - the Ultra C Pro, or the Note Air 3 C? (Assuming I only use them to read, not for productivity apps or internet?)

Thank you very much!

Fantastic review! This is exactly what I've been waiting for for this new model from Boox. Thank you a million for the detailed coverage. I am so impressed. Does anyone know if it's possible to use a USB-connected mechanical keyboard with either the Ultra C or Ultra C Pro? I use a topre-switch Happy Hacking Keyboard with the Supernote Nomad every day and would like a similar setup with a Boox tablet because of the Boox's larger screen. If anyone has experience using an external mechanical keyboard with these, please comment. Thanks! And thanks again to My Deep Guide for this incredibly thorough and enlightening review.

You can use any mechanical keyboard via USB hub or directly. It can even power the RGB lighting of the keyboard, if that is what you are after, but it will drain the device's battery more quickly.

if you're going to compare the Tab Ultra C Pro and Note Air3 C, I think you have to compare them without the cost of the keyboard cover.

Blunt question : with this kind of abysmal battery life, weight, etc. why use this vs. iPad or Samsung Tab S9?

[@MyDeepGuide]

Because of the E-ink screen and vastly superior writing performance and experience. And despite the "bad" battery life in extensive use, in normal use it still outlasts any of the LCD or OLED devices, because of the E-ink screen. That is, unless you are watching videos or browsing the net which has tons of animated content displayed on the screen. So for writing and reading needs, which is the primary use case of an e-ink tablet, this is still superior, including the battery life.

Thank you for your detailed review. Concerning the color resolution is only 150 dpi, while the black and white resolution is 300 dpi, I'm curious to see how writing with a narrow colored pen (e.g., 1px thickness) would compare to writing with a black pen of the same thickness. In particular, I would like to see a magnified view of the written words to closely observe the details of the curvatures in your handwriting. I need to know if there any striping or pixelation effects visible in the colored words? Additionally, I was wondering if one could create a pen with a custom color, or are the color choices still limited to a predefined palette with a very limited number of colors? Could you please make a short video or post me back here? Thank you

[@dmytrokostiuchenko3145]

I would also say (like the other commenter), that the comparison to your phone is flawed, but for a different reason. E-INK consumption is lower under an assumption that the screen is not refreshed often. IPS/OLED draw power to display the information. E-INK draws power to redraw the information. In other words, there’s no sensation in the fact that in the KZbin test E-INK performs worse.

[@MyDeepGuide]

While what you say is factually correct (yes, the panel refresh protocols do function that way), that is also why the only relevant and equal test is actually playing video content, as this is the only state where an E-Ink screen would be forced to refresh all of the pixels at every frame, like a regular display panel does. Anything else is a biased test that has no basis for comparison.

Again is it precuse in writting and and do all the functions that supports writting ( shapes , straight lines , photos upload to a sheath , synch , mailing , sharing to a printer !!! ,micro SD card ..) work smoothly and with many options. This shoukd be a writting and a reading tool and sharing tool. It can't be a computer . For that we have Ipad ans Sumsung TAB and Lenovo Yoga. Writting is a lot and if it is very very very good writting experience with having the ability to type than might buy one of this company devices. Might be Air 3 c.. since the camera on the c ultra as viewed totally sucks. If tge writying ecperience is smooth and natural and a bit rounded as a natural hand writting then this might be very usable for studing and work instead of paper assuming the quality is transfered by printing onto paper. 😂😂😢😮😮😅😅😊😊😢😂😮😮😮 For all writting apps in apple Ipad once you print a note to a paper the quality is so bad so what's the point of having nice writtings on a tan or an Ipad or a notebook yet on a print paper very bad results .

Your comparison with your mobile phone is flawed. You would have to increase the size of the phone screen to over 11 inches to be able to do that. Or at least separate the power consumption from the screen and calculate it for the bigger size.

[@MyDeepGuide]

Nope, as the phone has a higher resolution than the TUC Pro, so it's updating more pixels, meaning doing more calculations, consuming more power. Size has absolutely nothing to do with system load, resolution directly does.

[@skipper63400]

I commented that reading should be a better comparison, but you are right, your phone lasts longer on video than the TUC Pro with reading, so yes the comparison is valid
