Hi guys, my 2015 rMBP appears to been losing way too much power when I put it to sleep. I've read that entering standby mode the battery should last around 30 days. During the night, in the sleep mode for 9 hours the battery drained by 13%. My older 13" rMBP could literally over a week without losing that much power. My generally daily setup: Macbook connected to a P2415Q 4k monitor via DP-mDP Razer Naga mouse connected to Monitor, and usb uplink cable connected to Macbook. (Mouse is used in wireless via IR) Apple BT keyboard Harman Kardon Nova speakers connected via BT. When I sleep the macbook I close down all apps. Only thing I don't physically shutdown is Google Drive and sometimes Adobe CC (icons always up in menu bar) I usually disconnect all external peripherals, including charger. (though i turn it off at mains at night) So something appears to preventing my mac from entering standby mode I think, but i'm not sure where to start with isolating the problem. Help and advice appreciated! Alex EDIT: Important note, I usually get a "USB device drawing too much power" (or something along those lines) messages on wake up, sometimes two of them.
