Something seems a bit off with your numbers. If you're losing 5% of your battery "overnight" (at least 8 hours I assume), and you have the larger 86Wh battery, that implies a discharge rate of only 537mW.

900mw - nearly a whole watt - seems very high! Easily enough to cause noticeable warming - a running modern laptop at idle only uses 3-6 watts.

You're right, checked my notes and it loses 8% on average over 8 hours.

Agree that 900mW is high given that it's not supposed to be doing anything. It is what it is though ... haven't found a way to improve that.

Re. the comparison to idle power, I suppose there's a reason S1 is called "sleep2idle"!!
