On new iPhones “wireless chips can no longer be trusted to be turned off after shutdown,” according to researchers at Technical University of Darmstadt in Germany.
These wireless chips enable the phone to run on Low-Power Mode (LPM) to locate lost devices using the Find My feature. LPM is either activated when the user switches off their phone or when iOS shuts down automatically due to low battery.
And as the power saving mode is set at the iPhone’s hardware level, the feature cannot be removed with system updates. So, it has a long-lasting effect on the overall iOS security model, the researchers note.
Newer iPhones are Bluetooth-, Near Field Communication (NFC)-, and Ultra-wideband (UWB)-enabled, keeping them on even after power runs out. The trio have direct access to the secure element of the phone, exposing them to potential malware attacks.
The Opposition Congress demanded that the government open the Gandhi Vatika Museum, depicting Mahatma Gandhi’s legacy and freedom struggle, built at a cost of ₹85 crore in Jaipur’s Central Park last year, during the Congress-led regime in Rajasthan.

Pakistan coach Gary Kirsten stated that “not so great decision making” contributed to his side’s defeat to India in the Group-A T20 World Cup clash here on Sunday. The batting unit came apart in the chase, after being well placed at 72 for two. With 48 runs needed from eight overs, Pakistan found a way to panic and lose. “Maybe not so great decision making,” Kirsten said at the post-match press conference, when asked to explain the loss.
