i normally do a factory reset or clean flash for major version updates. Start on a clean slate. For me I actually find Pie a little better for my battery life on all the phones I've tested with Pie. Pixel, Pixel XL, Pixel 2, and Essential Phone. The adaptive battery thingy seems to work for me. But as usual with battery life YMMV one. Since we will have different apps installed, and maybe some apps you're using is buggy on Pie or what.
For me I personally dont feel any difference for battery life on my Pixel 2 XL from Oreo to Pie. No factory reset either.
I disabled adaptive battery because I simply dont like receiving late notifications due to an app being used lesser.
