Why is my LG Stylo 2 phone battery draining so quickly even when it's on it's charger?

[Android Central Question]

I have an LG Stylo 2 phone through Metro PCS. I love the phone but lately it's battery has been draining real quick. It also drains when I put it on it's charger. Could someone tell me why and what I can do about it.

Thank you, Michele

I've also had the same problem with my Stylo 3 Plus, and battery apps are telling me that EVERY app I have installed is contributing to battery loss.

The same thing started happening to me a few days ago. At 100% charge it states i have 50 minutes until the battery is drained.
