It seems like that 12h was speculation...On the other side I think, maybe no panic too quickly. These are all new devices and God knows what Windows 10 is doing in the background after fresh start up...? There might be a little tiny baby piece of hope left, that the battery life will improve after Windows 10 has settled down. In addition to that there might be firmware updates in the future which rescue the battery from it's weakness.
But on reddit there are SP4 Core m users that report up to 12h of battery life. That is weird.
Any m3 owners? • /r/Surface
I am still torn between m3 and i5 (which would offer me also a 256 GB option, which would be nice).
I just read that Winbeta is working on a detailed SP4 Core m battery test, which should be online early next week. Maybe that will be a good strike and lead me to my final decision. Life's so nasty and complicated... You can check it out later here:

My experience is that battery saver doesn't really do anything beyond stopping things like Windows update from running. Doesn't actually drop your power usage down, just stop other things from starting up.It seems like that 12h was speculation...
I ran yesterday with battery saver on from 100% and it didn't make any difference and oddly the display dimmed further at 20% (the default setting for battery saver) as if Battery Saver was just kicking in. This wouldn't be the first time settings didn't really do anything though.
Again makes complete sense. But you (and I mean you personally) know what a service is vs exe, what affinity vs priority of a thread means.I saw something on optimizing the Surface somewhere the other day. It suggested being selective about what syncs to OneDrive (or) turn syncing on during off hours.
I would like to see MS make a LowPower Profile i.e. battery saver on steroids that put's it into to 3W SDP mode. There's plenty of horsepower in this unit I think they could easily push this over the 12 hour mark if they tried.Now your getting into my area of battery life.
Glad to see it.
Quick note that app updates sometimes turn some features back on that had been turned off.
