iPhone 6 Turns Off when Mobile Data is On

[Alberto Chiong]

It does so when the battery is 70-80 percent. What seems to be the problem?

Welcome to iMore! Are you still using the original battery that came with your iPhone 6? If so I wouldn’t be surprised if your battery is shot. It could be another hardware or software issue as well though. I recommend resetting your network settings in Settings > General > Reset > Reset Network Settings. If that doesn’t fix your problem then a full restore of your device might be in order. Set your iPhone up as new to weed out a software problem.
