I personally installed four of these in my son's home alone three years ago, at least 2-3 of which were without a c wire. At the time I spoke to the Emerson Electric (mfr of Sensi brand and coincidentally local to where I live) technical support staff about their claim to not need a c wire (lots of other sellers claim no need but fail to point out that this means their devices rely on batteries which obviously die and usually at in opportune times). The technician's explanation was what I used in my post. It makes sense and I've read it online in other places confirming this. The units still work now and there's no way the batteries would have lasted that long.
Now that I've told you what I've actually done and my research with multiple sources, it's your turn to share with us. Have you installed one or more of these exact units? Did you call the manufacturer? Or do you just feel superior making negative comments? This forum is about sharing and helping others.
BTW, for anyone considering spending extra to get the color LCD version, be advised that model does indeed require the c wire. The one in the original post is monochromatic and it's simpler needs allows it to be operated without the c wire. If you wish to confirm, suggest calling the tech line. When I did, the wait time was almost non-existent, there was no labyrinth of menus to navigate, the technician was quite skilled, and their voice was easily understood. This was pre-pandemic but I hope that hasn't changed. The experience left me glad that I bought their product, which incidentally was not free at the time.
Since you were not on my phone call with technician, it's impossible for you to assume I misunderstood anything. Have you actually spoken to their technical support staff?
If you read my other post, you would see and read the documentation and the manufacturer link to it. Take the time to do so before making snarky comments. You should also reread your own quote and notice the operative word "backup". The batteries provide just the power to retain the settings.
Had you taken the time to read and understand the documentation, you'd understand that although you have a c wire and for some reason chose not wire the thermostat with it, you'd realize that your thermostat is being powered as I described and not by your batteries. If you don't believe that, remove them altogether and see that the device still operates consistent with what the manufacturer designed using the low voltage wiring.

need to go look into it now

Here's a review from the BGE Marketplace. Along similar lines to what kdiggz wrote above.
"
Ensure You have a Comminicating System
I gave a one star rating only because I was not able to use the thermostat with my communicating heat pump system. I was disappointed because otherwise the device appeared to meet my needs. Potential purchasers should ensure they do not have a communicating system. I saw nothing in the specs I reviewed before purchasing the device that it was not compatible with a communicating system but only that you needed to have a C wire going to the thermostat. Later, a tech pointed to a link opening up a compatibility chart that was more specific than the original specs I saw for the device. However, that chart was not available or obvious on the initial site I purchased the device from."

My thermostat cable has a C wire, but it isn't connected at either end, so it is running entirely off the internal battery. When the weather improves and I don't care if something horrible happens I will hook up the C wire. No, there is no reason to expect a problem, but there is also no reason to hurry; it is fine on batteries.
I did not sign up with the utility to save a bit and give them control over my thermostat.
