I'm switching to older hyperos versions for Houji, can I increase my battery life?

Hello, I am using hyperos 3.0.4 on my houji device and I am complaining about low battery life. Do you think downgrading to older versions of hyperos helps battery life? Which version of hyperos do you recommend for this purpose?
