WiFi near side of house

I have 2 doorbell3 and chimes. In one house (wood) the battery lasts for weeks with motion detetion turnerd off. On the stucco house with metal door set same way battery doesn’t last a week (usually 4 days). Unless there is something wrong with the doorbell I assume that it is due to the stucco (wire mesh) walls and metal door. Wifi strength is low in that site.

Suggestions???
