Users: did you encounter headphones losing energy before waking up?

Did Bose publish any charts regarding energy usage throughout a year, year and a half, two years of every day's usage of the Sleepbuds?

(how much the max capacity drops? 2 years would be 720 charges of the Sleepbuds)

My problem with sleeping occurs only close to wake-up time. 1-1,5 hours before my wake-up time it's easy to wake me up by the smallest sound and then I have a huge problem getting back to sleep.

Bose says that the energy lasts for up to 10h. If you use them every day and charge them every day, does the battery power capacity drop below 8h? (I sleep 7,5-8h)
