There have been many threads on this but have not seen anyone post evidence to show data usage from their phones to rule out apps draining data in the background. I’m experiencing the same thing as everyone has said, random blocks of exactly 100.00 MB of data being used, sometimes more (as much as 1600.00 MB in my case). Yesterday I received an automated text stating I’ve used 90% of my data for this billing cycle.
Here are some screenshots showing what the built in android data tracker is reporting vs what Koodo is reporting. I don’t expect them to be exactly the same but when the difference is about 6 GBs, something is definitely wrong. I don’t think rogue apps are to blame here.
