Thanks for the help. I have already tried clearing the cache. I even put the phone in airplane mode for most the day while I was at work and no difference. I thought for sure that would help but nope.
Maybe turn off location services see if that does it. If it doesn't, try maybe clearing google play services, turn off location history, clear play store data. Hope this helps. I've had several rogue news apps too that would use a lot of data in the background. Good luck.
