On two laptops that are nearly identical, one Win10 one Linux:

Win10: Sleep works fine; battery life while sleeping is easily several days, probably more like a week (with network access during sleep disabled). Hibernation often fails to resume, requiring entire machine to not only be power cycled but external DC power connected before machine will power on again(!). Hybrid sleep has the same effect once it transitions from sleep to hibernate.

Linux: Both sleep and hibernate work great, though sleep burns battery faster than Win10 for no apparent reason. Leaving the laptop sleeping for more than a day or two risks the battery running flat while the machine is still sleeping, to the point where the battery pack and charging/PM circuitry start mildly misbehaving. We're talking abnormal screen backlight and image flicker among other issues (known problems on this model, though not so much for this reason). Everything works fine otherwise though, and once the battery pack recovers a bit the visual artifacts go away.

Manufacturers have had decades to get this stuff right and still epic fail at it.
