Hi,
If I understood your comment correctly, we need to clarify few things:
- camera "recharging" means you have a 2-week window to work on your money and relationship, buying skills and upgrades, then the time rewinds and if you don't have necessary skills relationship level resets
- camera battery is a separate case - this is basically your stamina, if you're low on stamina after the running and getting ass kicked, the camera's battery during night fun will be low representing your stamina value
- the night adventure can end due to few things: time running out, battery (stamina) running out, getting caught by either Yuna or Kan, ending the night by clicking "end" next to the timer.
Hope this helps,
Cheers
