Missing notifications while phone sleeps?

Is it just me or does it seem like your phone misses more than just an occasional notification for things like google voice, gmail or various small items while the phone is asleep? For some reason my phone will be asleep for just a short time, then I click to wake it up and my notification shows up then, but if I hadnt woke the phone up it wouldnt alert me even though its set to check and notify. This happening to anyone else?

 

thats just too vague of a question for me to know how to answer.

 

two tests i just tried, opened google voice at 9:13 and refreshed it, then closed it and had my girlfriend send me a message through google voice. wait until 9:21 and the phone still hasnt given me a notification even though its supposed to check every 5 minutes. i click the power button and the notification arrives within a couple seconds.

so i open the app again refresh and have her send me another text at 9:23 and now ill wait a little longer, maybe 10 minutes to see if i get notified while the phone is sleeping.

 

currently its 9:33 and the phone hasnt given me a notification from the sms she sent at 9:24 even though its set to check for messages every 5 minutes.

 

i do have wifi checked as always on and half the reason i got an android phone is because i didnt want to have to push my gv sms to gmail or a regular sms plan. i had already been using it via this method with my iphone.

i finally got the notification 10 minutes later, and there were 2 waiting instead of just the one from her.

im doing another test now with mobile network always on enabled, she sent the text at 9:42 right after i refreshed and closed gv, now ill see how long it takes to get this one.

 

currently its 9:49 and no notification yet

 

got the notification at 9:50 when a gmail one came in. so i know they're definitely not coming in every 5 minutes, i never timed it until just now, but i could tell there were times it would miss when i was expecting texts
