Spike in mobile data usage on iPhone
Twice in the past couple of weeks I have experienced big spikes in data usage on my iPhone 8 (around 400MB each time I estimate). Both times this has caused my available data to drop to 0, then has drained my prepaid account of all funds as it uses casual data. Each time it happened I was completely unaware, and not using my phone. When I check my Mobile Data in Settings, the main 2 culprits are both in System Services:
- Home Screen
- iTunes Media Services
I now have zero confidence that I can go out and have mobile data switched on. I will turn it on briefly to check emails etc, then straight back off. Even in that short time (less than a minute), Home Screen and iTunes Media Services will rack up over 10MB each.
In addition, it has also caused me to notice that "Uninstalled Apps" are using data too (and yes, I have reset my statistics and not uninstalled any apps since the reset). I have seen this issue reported elsewhere, and it seems really dodgy that this could be happening. Though this is a much smaller issue than above in terms of amount of data used.
