LG G5 battery problems

[brianmccuk]

My LG G5 has started to drain the battery extremely fast. I can maybe get an hour to an hour and a half out a full charge. Ive tried a factory reset and one of these battery doctors which says the battery is in good condition but no change. Can anyone suggest anything?

How low do usually you let the battery get before recharging it? And how old is it?
