Hibernation Mode -25 isn't working on Macbook Air running 10.15.2

My MacBook Air is no longer hibernates when I close the lid. It just sleeps. In Terminal,

I have run pmset -g | grep hibernatemode. to verify I'm running in hibernation mode. Gives me a 25 result as it should.

When I close the lid at night and open it the next morning, my battery has dropped about 10-15%. typically, it will remain at what I close it at or drop 1% at most.

I've reset SMC and PRAM and it hasn't helped either.

Seems to have appeared with the .2 update.

Anyone else having this issue?

I tagged with Support and through the process, I discovered that Terminal was telling me I'm on Hibernate 25, yet About This Mac>System Report>Power..Battery Power was reporting it at Mode 3....so something was causing it a problem.

After all the diagnostics came back clean, Apple Support recommended a reinstall of MacOS while keeping files in place...so I did and now the Hibernation modes all match to the Hibernation Mode 25 on both Terminal and System Reports. I will test it and report back if this truly helped.

Hope this info helps.
