Another fact that adds to my bewilderment, is that some users report their battery life to be ok for them. Is this because they, for whatever reason (perhaps related to their personal phone-charging habits), manage to live happily along with the battery drain?, or is it because they're really not experiencing this problem? But then, if this is the case, what are they doing fine that me (and others) are doing wrong?
As I wrote above your post the problem exists but, with the tricks I wrote, charging it in the evening then the phone spends the night with a consumption of 10% and I arrive anyway in the next evening that I have 10-20% of my battery left. You can't have everything in life. After all we are using a very up-to-date ROM on an obsolete phone ... you have to find the right compromises. However, I also think that the ROM would have to be improved in this sense.
