Same issue here. MacBook Air 2015 11"
The battery was fine before the update, it used to last the entire day.
Since updating it lasts 2 hours max. I've tried everything: deleted Chrome, disabled some of the Spotlight Search categories, tried resetting NVRAM and PRAM, resetting the SMC, doing a reboot and booting into safe mode...
Nothing works. Still get the "service recommendation" message and the battery doesn't last at all.
Extremely disappointed. Hope Apple comes up with a solution...
