Deep Slip Issue With recent Lollipop ROMs

With Recent Update In Google Play service and CM 12's nightly most of the device and ROM based on CM12 is not going to deep slip as they were going earlier. 

There Some workaround for That if you are having that Issue.

1. You can just freeze the Google play service by titanium backup like tool but this may have some repercussions like  hangout may not work properly or stops working or apps relying on Google play service may stops working.
2. If your ROM has got wake lock blocker you can just prevent it with help of that just enable it and set it to block Google update service and Google Play service. 
3. 
   
4. This must be present in each ROM privacy In settings just click it it will open its menu open Privacy guard  go to advance like below snap 
   
5. Than open Google play service here you can disable wakeup and keep awake your phone. Have a look in snap fro my ROM do test it and decide which one serves your purpose. Don't forgot to disable auto start for Same. it is just below keep awake.
   

I would Like to give Thanks to gil80  has given this suggestion of privacy setting
