The keyboard is just as stable, or even more so, than the keyboard fold attached to the Surface. The tube and fold work together in an amazing bit of accidental engineering to keep it solid.
When using the adapter, the SP3 does not seem to have much draw at all.
Regarding the adapter battery itself:
I get about 3 hours of typing with my keyboard adapter per charge. The backlighting on the Surface Type Cover (SP3-style) keyboard takes a draw. With previous Type Covers, I got about 6 hours.
I found that I can dim the backlighting, though, and get closer to 5 or 6 hours with the Surface Type Cover. Of course, I can use a micro USB charger cord, and not rely on batteries at all.
Check out this use with my iPhone!

I have the adapter that I bought for my SPro 1 last year and I've bought a SP3 last week. i5 , 256Go. I'm trying to have it detected (pair it) to the sp3 and it's is'nt working. After a few minutes of "working"" i get a error message that it cannot be detected (please be sure that your device is still detectable...).
I've no problem to detect pair other bluetooth devices with my new surface pro.
Anyone has an Idea ?
of course, but you're right to ask. The white led is flashing rapidly, and we can see on the screen the graphics animation that the pairing process is going on, but it take forever compared to the sp1, finishing with the error message mentionned before. The adapter just finished to charge overnight..
