Battery draining quickly after Windows 10 update

Pavilion 15 ba113cl
Microsoft Windows 10 (64-bit)

I recently installed the WIndows 10 update and since then my battery has been draining quickly and erratically.  It will drain from 100% to ~40% in 13 minutes even in battery saver mode. Under 40% and it will randomly shut the computer down. Frequently it will jump from a lower percentage, like 50% to 61% if I close one tab in the browser.  I used HP Hardware Diagnostics to run the battery test and every time it just cancels mid test.  I then tested it with HP support assistant and it said the battery was weak.

 

I figure it has something to do with drivers after the update and not the actual battery itsefl, but I thought I would ask here first.

 

Thanks
