Hey guys, forgive a potentially stupid question, but I just bought a new 2015 Retina MacBook Pro, and I noticed today that after about 13 hours in sleep mode, the battery had lost 13% battery life (1% per hour). Is this normal? Apple Support said this was norma. They checked my Energy Saver settings and Battery info and said everything looked great, and that I could always just shut down the laptop entirely if I didn't want to experience any battery loss. Does this jibe with your experience? Should I have any reason for concern? I don't really have anything to compare it to, as my laptop prior to this was one extremely old and the battery life had been absolute crap for years. Thanks!
