On June 13, Fast Technology reported that since the iPhone XR/XS, Apple has launched the "power reserve" function. When the power is exhausted, it can also support the NFC swiping and location searching within a few hours.
After experience, the iPhone 15 series has brought new functions after upgrading iOS 18. You can continue to display time, search for available functions and other information on the screen after the battery runs out.
This function is exclusive to the iPhone 15 series and cannot be realized by the iPhone 14 Pro Max. At present, it is not clear why Apple displays this function on old devices.
It is worth noting that Huawei has also launched an "emergency mode" with similar functions since the Mate50 series, but it has more functions. It can still call and scan codes when there is almost no power.
According to the test results of Huawei's laboratory, when the concentrated energy pump is started intelligently at 1% low power, the mobile phone can continue to stand by for 3 hours, or talk for 12 minutes, or light the code 10 times, or scan the code 4 times, and will not damage the battery life, so as to solve the user's urgent needs.
When the battery is about to run out, the phone will pop up a notice that "emergency mode will be entered in 60 seconds", and then enter a pure black background somewhat similar to the information screen display effect, similar to Apple's battery run out interface.
The difference is that Apple only displays information, while Huawei makes calls, sends messages, scans, etc, You can also make an emergency call before disconnecting, or scan a shared power bank to renew your life.
