I have the same problem. My phone is a Droid Maxx running Android ver 4.4.4. I believe this is an OS problem but have learned the way the phone is turned off is key to avoiding the problem.
Depending on how long I hold the power button down 1 of 3 things will happen. A brief press of less than a second and release puts the phone into a sleep mode blanking the screen and disabling its touch sensitivity.
A press of more than a second but less than 8 seconds gives a popup. Using the popup spells trouble. More later.
A press and hold of more than 8 seconds powers down the phone. If I power down the phone this way it always restarts in the last mode it was in before powering down. If in silent mode it stays in silent mode. If in audible mode it stays audible. This is the way I will power down from now on.
The popup you get if you hold the power button down between 1 and 8 seconds gives the choices of power off, airplane mode or silent, vibrate and audible modes. If you select power off it asks for a confirmation. After powering down this way my phone always powers back up in silent mode. It does this whether you were in audible, vibrate, or silent mode when you powered off. So watch out. I don't believe the OS should perform this way, but it does so I'll avoid it from now on.
