This seems surprisingly high to me, unless you're constantly on extreme power saving mode. I liked the 4a and still have it in a drawer, but replaced it partly because I couldn't order a new screen and the battery life was frustratingly terrible after a while
It seems to in my house - possibly the wifi signal is not strong enough where I leave my phone and it is constantly searching. I also find that on wifi data, apps constantly update and sync themselves - they don't do this on metered network data.
