97% since launch day for my Max. My charging routine..... When I go to bed I'm around 20 to 40 percent. If I think I'm going to do some reading on it before I turn in, I'll stick it on the charger for 20 minutes while I take care of the pre sleep stuff (shower, teeth, etc). When I hit the sack at 11pm it gets hooked to an Anker charger and it probably hits 100% at around one or two in the morning. And of course it's trickle charging after that. At 6:30 am it's off the charger and on to work. Rarely if ever charge at work. I'm giving all this otherwise too-much-information-detail to see how it contrasts with others who have a lower battery health. I consider 97% excellent.
