I have been struggling with battery calibration for as long as I can remember, even when making a point not to charge the phone until it is close to empty. Seems the calibration continues to drift higher than the energy-full-design value in most cases anyway, as described in this post.
Doing complete drain/reharge cycles is very impractical with a phone where battery usually doesn’t last a full day, so is also constantly carrying a power bank.
For me, no calibration (i.e. after reinserting the battery) is better than the inevitable calibration drift that overestimates the remaining battery life. I think this is true for many L5 users, as I often read about the L5 battery going from 30%/40%/50% to zero in a matter of minutes.
