I have an Alcatel TCL A 1 "burner" phone, (also known as A 501 DL) with Android 8.1 - it's one year old. The battery seems to get drained very fast. I barely use the thing and when I do it's usually only for 10-15 minutes and I'm careful to turn it off. The phone is supposed to give "up to 9 hours talk time" - I realize that battery life depends on a lot of things but is there any way I can improve the length of each battery charge. This old Luddite thanks you!
