Hi *, On my Dell XPS-13 9365k Notebook I experience pretty accurately a battery drain of 5% per hour in suspend when running Ubuntu.
Compared to this 5% per hour battery drain while in sleep, I've found a maximum battery drain of 2-3% independent of sleep time when the Dell Notebook 9365 runs Windows, which is a huge benefit. On Windows I can afford putting the notebook to sleep always, whereas on Ubuntu I have to balance the choice with the time I expect the machine being down - a big drawback. I assume 'they' (on Windows) have a mechanism in place that changes the state to 'hibernate' after a certain time. For example when I wake up the 9365 after half an hour from sleep, it comes back very quickly, and when I wake it up after one hour from sleep it goes through a booting process that takes much more time. If this is true, I am asking whether we could have a similar behavior running Linux on these machines. To me such a procedure looks very sensible: Having it waking up very quickly within half an hour or so and limiting the battery drain to a couple of percents. This is exactly what I would wish. So I am asking whether we could have a similar behavior running Linux on this machines? By the way: Is this the right location to ask such a question? Thank you in advance for your time and effort to look into this.
