I retired my iPhone 8 a couple of weeks ago as it’s causing issues , home button stuffed , battery life hopeless , cracked screen and so on …. It served me well over 7 years
Bought an iPhone 14 and noticed it’s using excessive data ( like 3 or 4GB per day ) and I hardly use it.
Battery usage is fine , extremely efficient compared to the old 8
My usage habits have not changed between the old 8 and new 14 , so I changed some settings ……
Set phone to low data mode
Switched off all notifications
Switched off all apps not used
Switched off Bluetooth
Switched Data Roaming off
Personal Hot spot off
Aeroplane Mode off
Switched off various other controls/ settings not required

I’m sure the phone is using excessive data in the background somehow ??

Any other advice welcome from mobile phone gurus

Thanks in advance
