Background tasks on Mac laptops can create a similar problem, but they are largely software created, and rarely out-of-the-box scenarios. Enterprise security tools like endpoint protection scanners and VPN clients made available for Mac but seemingly built in a different power state mentality have been shown to interrupt sleep mode and drain battery. I've also heard mixed reports of different generations behaving badly, and I haven't used all of them. In college my MBP lived in my backpack. You finish a class, close the lid watch the light change and away you go. Nothing will wake it until you open it.

Now with enterprise scanning tools running for "security" they check in daily or hourly to look for new threat signatures or what have you, no matter the power state, no matter the network state, no matter if its in a bag. Likely because the bulk of the tool was just ported from a world where you turn it off or the computer isn't off.
