I wonder if the people on this thread that complain about the battery life shortly after buying it use the vacuum in its "turbo" or "power" modes.

I purchased one of the LG stick vacuums and I've vacuumed almost the entire house with it. Whereas my housemate picked it up and vacuumed one large room and the battery was half flat, he complained about it, then I caught him vacuuming the entire room on the boost setting simply because he wanted the most suction possible. But it wasn't needed at all.
