Battery saver switching off independently

I use battery saver all the time when i dont have an activity and recently it switched off by itself, i have sleep mode switched off, does anyone know why it does that? i want it to remain under manual control

Check your settings on Sleep mode. It lets you enable or disable features like power saving, wifi, watch face and so on.
