What series are you using? I have the S11 and in 15 minutes it easily charges from 10-20% to 80-90% which gets me through the next 24 hours.
Not the parent but I have the Ultra 2 and it lasts around two to three days on a charge, which is nice, but there's no charging routine that looks attractive to me. I end up sucking it up and trying to place it on the charger when I wake up, under the assumption that I'll pick it back up once it's fully charged (and not only the next time I go out or to sleep)
Series 9, which I'll probably be upgrading this fall anyway.
