Is this just my laptop? (Battery after Windows update)
Ever since last week's update, the fan goes crazy when waking from sleep mode. Battery life also feels like it's been cut in half...
If anyone has experienced the same issue, please leave a comment.

Same here, seriously... when it wakes up from power-saving mode, I swear the fan is getting ready for takeoff lol
This has been going around as an issue with this month's patch KB5xxxxx, but first try lowering 'Maximum processor state' to 99% in Power Options. Also, rolling back the Intel Management Engine driver (ME) in Device Manager often significantly reduces fan noise. I fixed it that way. As for the battery, pull a battery report and compare design capacity with full charge capacity.
But wasn't that the same story that circulated around a previous update? To keep blaming every update, a battery dropping to half could just be the cell's lifespan running out. Do you have measurements taken under the same conditions before and after the update? If not, there's a chance it's just placebo.
Got a source?
When your fans spin up to full speed after waking from sleep, it's usually because background tasks pile up at wake time. In Task Scheduler, check the triggers for 'Microsoft\\Windows\\UpdateOrchestrator' and the search indexer (SearchIndexer). Often the culprit is the follow-up tasks that run afterward rather than Windows Update itself. And if you use hibernate instead of sleep, the symptoms almost disappear.
Oh, I didn't know this. I just used it as a reference, but I should try it out.
