notification delay when on sleep

[Jrnr]

HI has anyone experienced delayed notifications.. they all arrive too late at times.

I have the same apps on my iphone and some of them arrive nearly 10 mins late on my xperia..

I dont use any power saving modes, and unrestricted data is ticked; still the notifications are delayed.

Does anyone know any fix? I hear someone say disabling google app will solve it but I dont want to miss some features which are very useful to me.
