IPhone vs pacemaker

My wife has recently been fitted with a pacemaker. However, reading a website, I note that the latest iPhone 12 can interfere with them. I gather Apple has issued a warning.

This was news to the hospital team involved with my wife’s pacemaker, but they gave no guidance. Do you have any info? COLIN STEVENS

The MagSafe tech used in the iPhone 12 relies on magnets to work, and this can cause interference on some medical devices. However, while US researchers did raise the alarm — which led to Apple issuing its guidance at bit.ly/ ml184_magint — the risks may be overstated. The best advice is to talk to your doctor or pacemaker specialist.
