There are four driver updates in total: one for the Surface Management Engine, another for the Surface UEFI, one for Surface Integration, along with a driver update for Surface Integration Service Device.
The first two tweaked drivers are both designed to ensure better stability and enhance performance when switching between different power states on your Surface.
Balance of power
And the final update addresses the default power plan, which is 'Balanced', and ensures this stays correctly set whenever Windows is updated (given that this is a post-Anniversary Update set of fixes, we can only guess that said recent major OS update broke this power setting in some respect – it wouldn't be the only issue caused, that's for sure).
But the most interesting tweak is the third update for Surface Integration which Microsoft says "improves the device usability and battery life".
That (obviously) suggests overall battery life is going to be better, which is always very welcome. Back in June, the company also boosted battery life with a Surface Book update, although this was aimed at optimizing battery usage only when the device was in standby mode.
Some Surface Pro 3 users (a minority according to Microsoft) have had far more to complain about on the battery front, but at least the long-standing SP3 bug that resulted in the errant reporting of a lower battery capacity has finally been patched this week.
All in all, it's a good week for Surface batteries everywhere…
