Phal with droopy leaves

[littleone]

I've been taking care of my Phal all year but was gone for a week and forgot to water before hand. I came back to one droopy leaf and one wrinkled leaf that looks soft.

I watered it already (soaked in water 10 min) but now I'm not sure what else to do or how I can make sure it's making progress. What kind of time frame should I see improvement in?

I was going to put it outside a few nights for cooler weather in the winter since it lives inside right now - should I still do that?

Any advice appreciated. This is a basic store bought phal from a grocery store that I've had since last February.
