Battery life is the major lifestyle challenge of the age, when our smartphones are often the hub of our lives, and those devices can’t function without juice. You’re out of your house, totally reliant on your phone – whether for navigation, memories or something else – and the dreaded low battery icon appears. So last year Apple designed its latest software update iOS 18 to make sure you are never truly off the grid. Here is how the company’s ingenuity means you can still tick, even when your iPhone runs out of fuel.
Recognised by alert Redditors and spread across MacRumors, there’s a small but significant new feature in iOS 18 that will make iPhone use ever so slightly better. When your iPhone’s battery is running out, iOS 18 will display the time in tiny text at the top left of your iPhone’s display, so even when your iPhone is nearly dead, you won’t be completely lost in time.
This is not an energy-preserving but a qualified life-supporting mode, with the remaining battery energy reserved for the vital few rather than the trivial many. Power Reserve mode is not entirely new but also not completely trivial: it has been built up with a supplemental clock display. While this residual battery power is not squandered on mere chronometry, it offers much more than mere survival. Namely, enabling you to find the lost iPhone, together with the capability to make contactless payments and to use digital keys even when the battery charge is too low for any other tasks to be performed on your iPhone.
Notwithstanding that this sci-fi feature is only available on new iPhones, there’s a few catches. Notably, for reasons not yet sufficiently unraveled by tech aficionados, this ‘Power Reserve’ clock is rolled out only with the iPhone 15 (time of writing: as part of the rollout of iOS 18). Why? Why not for old models? Is Apple simply being a bastard, working to force users to upgrade to newer models, or is this some quirk of technical feasibility still being hammered out in the beta phase? Like most people writing about tech, I have no idea – only time will tell.
If you’re an iPhone 15 user itching to try out this feature, the iOS 18 developer beta is available to download. But for everyone else, the thing to do is wait for the public beta or the final release in September. Caveat emptor.
And while the addition of the clock to the Power Reserve feature is the standout thing about it, the reality is that it’s the tip of the iceberg too. There’s a whole lot coming for iOS 18 that will change the iPhone for the better. There might yet be AI ideas for it, just like there are for the iPhone 15 Pro, but it’s Apple Intelligence where the big ideas sit right now.
With every iteration, Apple strives not just for greater functionality but also for our devices to get more intelligent, more responsive to our needs. The future glimpses offered by Apple Intelligence suggest a time not too far off when our phones are no longer simply servants of our every need, but proactive partners in the maintenance of our digital lives.
And at the center of these advances, Apple’s commitment to innovation and to user experience. As a homegrown California company that grew from a garage to a tech giant, Apple put a stake in the ground for what technology can do. Their focus on the thoughtfulness of hardware and software creates life-enabling tools that enable creativity, connection and convenience in countless different ways.
