Is Framework 13 AMD s2idle (modern standby) efficient enough?

There are other topics dedicated to troubleshooting issues with suspend, however, I believe, in my case, it works as intended, but… I am not sure it is good enough.

I will be focusing on Linux since this is what I know, but, based on what I read in other topics, the situation on Windows is similar.

Here is a specific data point:

  • Last night, my laptop was suspended for 39930 seconds (roughly, 11 hours and 5 minutes).
  • Of those, it spent 39923 in hardware sleep state, that is, almost the entire time (the difference is 7 seconds, which, by the way, is pretty large – normally it is more like 2 seconds, and I am not sure what was different this time).
  • The battery went down from 70% (2744 mAh) to 62% (2460 mAh).

This gives us a rate of 0.65% (25.6 mAh) per hour of sleep. Elsewhere on the forum, I saw people report the rate of around 1% per hour on Windows, so, comparable.

Now, here is the question that I keep asking myself: is this good, merely acceptable, or bad? E.g. this means that the battery will be essentially empty after 6 days of sleep. My personal feeling is that this is sort of acceptable, but I would definitely wish for much more.

Microsoft seems to agree! Their Modern Standby Duration Test says:

Systems that support Connected Standby are recommended to drain less than 5% of system battery capacity over an 16 hour idle period

If I scale the result of my experiment, I am getting the drain of 10.4% over 16 hours – more than twice as much as recommended and it is not even Connected Standby as in their test.

So, where do we go from here? @Mario_Limonciello’s script doesn’t find any issues with my system and, given that it spends pretty much the entire time in the deepest hardware sleep, I suspect there is nothing I can really do to improve the situation on my own, at least not on the software side.

Should I be looking for more power efficient hardware parts? Is there anything that Framework can do to reduce the drain? Can AMD help?


It’s certainly not Macbook level of efficiency. However, it’s comparable to my other Intel Chromebooks which are using probably the most battery-consumption optimized Linux laptop platform.
