Why is my News & Weather app using so much data (and battery)? I'm running Android 6.0 on an HTC M9.

In the last 13 days, my News &amp; Weather app has used 1.37GB of data. In that same period, Google Play Store used 1.22GB.

For a few weeks now I have had severe battery issues (from around 36 hours of light use down to 4 hours - 5 if I leave it on my desk and do nothing), and I'm now assuming that this is the cause. I don't know why a news app would use so much data, and it's all background data which makes it even more shady.

Has anybody experience their News &amp; Weather app going out of control like this, and does anybody know how to stop it?
What you need to do is delete your weather app, revert the Google Play Store to the factory version, and then wait a day or so. In my personal experience, this will stop both of them from transmitting so much data, and restore your battery life to normal levels.
