How to reduce the current consumption from the battery in the reception mode on the Baofeng 888S radio station?

Question

Radio communication

The radio station is used only for signal reception. The current consumption in standby mode reaches 70 mA, which in my opinion is quite a lot. At the same time, I do not use the built-in battery saver function due to the fact that the radio station "falls asleep" after it is turned on, and monitors the air somewhere every two or three seconds. Because of this, there is too much delay in receiving the signal. Who knows if something can be done. so that the radio station eats less in the receive mode?
