Running Rebelle on Microsoft Surface tablet

Can I ask anyone here if they running Rebelle on a Microsoft surface tablet and specs and typical battery hours you get ??
im thinking of moving from surface book 1 to surface pro7 tablet and trying to see what to expect in battery use.
Thanks

Hi Bob, I just got a refurbished Surface Pro 4 tablet, and I'm getting less than 2 hours on battery. I am wondering if this is a bad battery, or if Rebelle3 just sucks the battery that bad, too? I have no way to know, except to ask others. I do see where it seems to have been a problem with certain Srface tablets... Sorry, no help. Just tagging on...
