Just upgraded from a macbook pro 13 late 2011 (with self fitted ssd) to a RMBP 13 2015. the late 2011 when i closed the lid slept and if i ever checked the syslog only woke when i re opened the lid. The new RMBP seems to wake every 2 hours (no power nap enabled) usually with a ATC alarm or ATC wake network. the only time it will sleep and not show any wakes in the syslog is when i turn the wifi off before sleep. if i do this it doesnt wake till i re open the lid and the battery hardly goes down maybe 1% in 8 hours. if i leave wifi on it will wake every 2 hours and drain between 5-10% of the battery. anyone else had this problem and fixed it ?
