My LG3 phone has recently started draining too fast, even when not being used. It has also been heating up, while sitting and with use. All updates have been installed and have deleted an app that was recently downloaded (a baseball app) to see if that would help. It did not help. I charged the phone to 100%, did not use, picked it up at least 3-4 hours and the phone was dead. Any help is appreciated. The phone is only about a year and a half years old and is very well cared for.
