[Q] play services keeping phone awake draining batteries topic

My phone has always been awake when screen turned off and I think the play service is causing the problem. As shown in the pics I used the app ops to disable the play services permission to keep phone awake however it doesnt seem to work. Now my battery is being drained super fast even though I have my screen turned off most of the time. Anybody can help me identify the real reason why the battery is being drained so fast and why play services are still able to keep phone awake even though its permission to do so has been disabled? Thanks.
