SP2 and power cover.

[Darren Donovan]

I see Battery 1 and Battery 2. Which is the battery in the cover, and which is the battery in the SP2?
When I tap on the battery icon, it shows 1220 hr 50 min remaining. Does the "1220" mean 12 hours + 20 minutes? And the total time remaining is 12 hours + 20 minutes + 50 minutes?

Thanks,

cover is battery 2.

So does Battery 2 (cover battery) always drain first before power is drawn from the SP2's battery (Battery 1)?
Thanks,

The Power Cover keeps the Surface Battery at 100% until it is drained, at which point the Surface Battery kicks in, during charging the Surface Battery charges to 80% at which point the Power Cover charges to 80% then the Surface Battery charges to 100% and then the Power Cover will finish charging...

Thanks for that info, pretty elaborate sequence.

not allways true. they have been doing wacked out things, ive seen power cover charge 100% and surface is at 23%.. i would say the only times i see the odd charging is when im gaming and its docked witht the power cover on. but non-docking station it does seem to allways fallow the above rules
