rMBP Early 2015 wakes from sleep every minute

Changed my hibernate mode from 3 to 25 via pmset. This forces Mac OS X to always hibernate to disk, and power off memory. Wakes are a bit slower but battery drain is gone.

Would like to have proper solution, though.

Command:

sudo pmset -a hibernatemode 25

Excerpt from man page:

hibernatemode = 25 is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery life, you should use this setting.
