I too have noticed a large increase in wireless data use since getting my Turbo. I know I'm using it more because is fast and I like it, but it's more than that. I poked around a bit today and learned some things.
1) I downloaded my wireless data usage details from the Verizon website. I found out that a fairly large quantity of data is being used while I know I'm connected to my home Wi-Fi. I can verify usage from 12/3/14 to 12/19/14 of
85MB while Wi-Fi is on and I'm connected and I suspect another
340MB was consumed just at the end of Wi-Fi use or just immediately after disconnecting from Wi-Fi. I suspect this time of day due to it being about the time I leave for work at 6:30am (+/- 15min depending on how motivated I am
. That total of 425MB is nearly
40% of my
total data usage this month so far!
2) Perhaps the more interesting & somewhat concerning thing I learned was a feature I thought I understood under the android wi-fi settings (Settings/Wi-Fi/Advanced) called 'Scanning always available'. I thought this option was just used for better location reporting. However, according to Verizon's support page this option is actually used to assist data throughput. Details at the link below:

Based on this article I disabled this feature to prevent usage of wireless data while connected to Wi-Fi. I will monitor data usage while connected to Wi-Fi and report back any findings from 12/19 on. Maybe we can have another member look this over to sanity check their usage as well. Better yet, maybe one of these outstanding fellows
@94lt1 @cr6 or
@FoxKat can confirm or deny this is an existing/known issue on Droid Turbo or other phones.
