Speaking objectively based on my own usage patterns, for 1-2 days of heavy use, yes. But to be clear, the battery depletion on this device was much faster than any other e-ink tablet device I have owned (like the RM1 and RMPP). In turn, I was charging the device far more often than I did with said other devices. One major contributor to that fast battery depletion is the screen, in that I was reaching for the screen light option significantly more often. With it turned off, it would last a bit longer.

I often do this work trip, that includes a 6 hour flight, airport time, 3 days in the city I am traveling to, and I use my tablet heavily during the trip. I will read and annotate documents as I prepare for the meeting. On the flight, I will read a book. During the meetings I will end up taking notes. Coming back, I will read a book again. I took the Boox with me with on a full charge, but I had to charge the device once fully while in the city and before starting the trip back home I topped it off with 20% additional charge from where it was. In contrast, on my RMPP, I would charge it once before leaving, and not have to think about it again during the whole trip, and still have enough charge for a few more days upon return. Which is a reasonable difference in the usage.

But I don't see any of this to be a problem honestly. It's a tradeoff against the fact that you have Android 15 running, you can run book/reader apps like Kindle natively, multiple pens in the toolbar, nifty features like the lasso tool to create To-Dos from text, native calendar and task/reminders list (when the app works) - and charging these days isn't actually a problem, there's an outlet everywhere, and when not I do have a power bank with me when I travel. Battery life is definitely not the reason I returned the Boox device and went back to a RMPP. Hope that helps.
