I know I actually tried to delete my post because after turning my phone onto flight mode then turning it on again it works, again.
I am a little embasased now but it doesn't always connect to both bands straight away. It may be my router,I have an Asus RT ac 88 U that's probably about three years old now and the 2.4 GHz radio is not very good anymore. It's slower than it used to be ( sometimes a reboot helps)
Maybe it's time to go shopping

Do you think it uses much more battery when on dual WiFi ?

I believe it uses MUCH more battery.
How I came up with that decision. At home I use dual WiFi for more stable connection and it works fine. When I go to work, I'm disabling that feature, because I can't use it in subway. Usage scenario is the same, amount of active screen is the same. Mobile signal strength at home better then at the office. So:
Regular day at home with dual WiFi, by the end of day (21:00) I have ~20%
Regular day at work without dual WFi, by the end of day (21:00) I have ~45%
I am not complaining, but for me it works like that.
Wifi at home is Xiaomi Mi Router 4A
Wifi at the office is Cisco AIR-AP1832I-R-K9
