Wake up takes a long time

[Zolotoy]

It takes much longer after dbl tapping to wake up then after pushing a power button. Any idea?

Thanks

I ran into this problem and a reboot fixed it.

Check if your battery is swollen.

Did you enable Windows Hello / Iris Scanner? I noticed on my Lumia 950 that without Iris, the display wakes up quickly via dttw.
