Many users are facing problem of Excessive mobile
data (cellular data) usage. After the iOS upgrade with normal operation the
users are seeing high data usage of cellular data. The data usage increase is
reported to be from 100 Mb/day to 1GB/day. At the same time it is very annoying
because eats iphone battery. On close debug the problem is seems to be increase
in DNS request with iOS 13. 466Mb of DNS requests are something like 5 billion
requests.
Some user
tried to do network reset but did not help and iOS 10 consuming mass
quantities of data issue persisted.
What is the DNS high data excessive usage problem and how to fix it:
The
problem is with Apple iCloud. iCloud now syncs to all devices the desktop and
documents folders. The feature is great but it will also sync your MacBook data
with your iPhone.
In new
release by Apple, there is a switch on iOS 10 "Use Cellular Data" that is ON
by default. So if you put some heavy file on any Apple device, desktop, that
file will synce to your iPhone using cellular data
Turned cellular
data off, exvcessive data usage would stop.
1.
Go to Setting
2.
Settings->iCloud->iCloud
Drive
3.
Scroll Down, until you find
out the “Use Cellular Data” option
4.
Turn it off
Hope this worked for you.
