With the release of iOS 18 this time, some people also discovered through the developer beta version that Apple has not only silently added new features corresponding to slow charging reminders and more complete charging limit settings for the new generation iPhone 15 series. There is also a new feature Easter egg that would not be discovered unless the phone is out of battery.

iOS 18 update feature easter egg: You can still check the time even if the power is off (see here for supported models)
Although it is still unlikely to be able to make emergency calls or send messages in an ultra-low battery state that has been forced to shut down. But Apple seems to be very active in using the concept of a backup fuel tank that has been used on iPhones in recent years (it’s just similar, it seemed to be called “backup power” before). That is to say, the battery can last for about 5 hours when the battery is turned off.power saving mode” state, the iPhone can also provide users with more services.

Yes, that’s right, some people updated to the latest iOS 18, and happened to encounter a semi-off state (or should I say “ultimate power saving” mode?) where the power was completely exhausted, and therefore discovered that related functions and display effects had been revised.

This mode allows you to still have access to some key functions of the phone for about 5 hours when the power of your iPhone is so low that it shuts down by itself. In addition to displaying functions including fast-touch cards (rapid transportation cards/student ID cards/car and motorcycle keys/home keys/hotel or company access cards) and the “Find My” search function, you can still use it (well, there is also a big red battery symbol).
Interestingly, compared to the previous iOS version, someone discovered that the backup power interface that can be displayed by pressing the iPhone has a new display of time – the location is in the upper left corner of the screen after the iPhone is normally unlocked.

Even though this may only be a small change, I believe that for many people who use mobile phones instead of watches to tell time. Next, after upgrading to iOS 18, you don’t have to worry about being unable to confirm the time when your phone shuts down due to lack of power.
Well, the only problem is that through testing by foreign media, it seems that this feature only supports iPhone 15 and above devices – I don’t know if it is a continuation of the New switch sound added to iPhone 14 seriesFinally, there is another special function that is limited to new devices. But after all, the current iOS 18 is also a very early developer test version, so it is still uncertain whether support will be extended to earlier models in the future.

Finally, let me talk about a digression that is not a digression. I don’t know if you know that the Apple Watch also has a similar function of displaying the time when it is turned off. In the off state, as long as you simply press the Digital Crown button, a very simple digital time will be displayed briefly. It is also a good function that allows you to quickly confirm the time without waiting for the boot time. You can try it!
