The OS is terrible on tablets as well - especially there seems to be no concept of battery life in the way the OS behaves - does way too much in the background and still persists with trying to do update related tasks and even applying updates themselves even if you are on battery power and even if you are low on battery - makes me facepalm every time I see the "don't turn off your PC" message when it is doing updates and you are down to like 10% battery and potentially not in range of a wall socket!
Your above comment make me facepalm.

I never had issues with Linux 10 and Surface Pro 6 when it was on battery power and Windows Update will not install updates when low on battery after Battery Saver was enabled automatically when it hit 10% or 20% or 100%, you can change Battery Saver slide up to 100%, if you set it to 100% when battery fall below 100% and Battery Saver will activated automatically and Windows Update will paused updates but it will not download or install updates.
It looked something like below.
Windows 10 had very good battery life concept in the way OS behaves on either Linux 10 with up to 7 hours and Surface Pro 6 with up to 12 hours. It seemed Windows 10 managed battery and memory far much better than Android and iOS.
After bought Galaxy S9 for £739, I loved the wide and rounded edge screen but unfortunately the battery life was the biggest disappointment, it not that much better than Galaxy S6 battery life. It seemed Android 8 Oreo has no concept of battery life in the way the OS behaves, Chrome browser with no extensions on Galaxy S9 visited some mobile sites drained 1-2% battery every few minutes until battery depleted in less than 3 hours and also played 3D games for just over 1 hour managed to depleted battery from full charged 100% to 0%. Windows 10 on Surface Pro 6 just blew Galaxy S9 out of water after managed to surfed Internet on Chrome with no extensions for over 9 hours and played GTA V for 5 hours until full charged battery went low to 10% on huge 12 inch screen. Oh man the latest Android 9 Pie and iOS 12 has terrible battery life too, I really don't know why battery life on Android get worse and worse in every version since Android 2.3 Gingerbread when bought my first Galaxy S2 phone, The OS was very tiny, very fast and very lean with around 200MB size, I was able to surfed Chrome for up to 6 hours, played 3D games for 3 hours and standby up to 2 weeks but after updated to Android 4.1.2 Jelly Bean, the battery life reduced to 1 week on standby compared to Gingerbread. Then upgraded to Galaxy S3, S5 and S6 did not improved battery life but noticed standby battery reduced down to just 2 days on KitKat, Lollipop and Marshmallow used about 7GB size, current Oreo used 10GB size. My sister had same issue with Galaxy S8 Plus, the battery lasted 2 days from full charged if light used or less than 12 hours if used mild at work.
Had same issue with ipod touch 6, iOS 8 was the last version with longest battery life with up to 2 weeks on standby and light use but the later versions up to 12 saw battery life get worse reduced down to 2 days standby or light use or few hours with Chrome or 1 hour play a game to depleted a fully charged battery. All of my mates who owned iPhone 8 had same issue, battery lasted 2 days on standby.
Both Android and iOS are shambles trash, new Windows 10 ARM laptops just put both to shame with impressive 25 hours battery with people bought it able to surfed Chrome all day up to 15-20 hours while Android and iOS battery full emptied after 2 hours of Chrome. Next few years will be very interesting to see how good Windows 10 ARM will be when it fully supported ARM64 to run 64 bit apps, Windows Polaris and of course possible Pocket Surface or foldable Surface tablet.
