Your current iPhone battery could last longer with iOS 19, thanks to AI

Imagine downloading a software update for your current iPhone and the battery life getting extended. That could be a reality thanks to iOS 19.

According to a report by Bloomberg’s Mark Gurman, we can expect iOS 19 to leverage AI in such a way as to actually improve battery life efficiency on iPhone.

This will apparently be classed as an Apple Intelligence feature that’s called battery management.

Possibly the best part is that this new battery life extension could arrive as soon as this September, when iOS 19 is expected to roll out following its announcement at WWDC 2025 in June.

What is iOS 19 battery management?

According to the report, Apple is planning an AI battery management system with the next software update. But how does it work?

Allegedly the AI will work to analyze just how a person uses their iPhone and will then make adjustments to best conserve power.

Gurman writes: “To create the technology — part of the Apple Intelligence platform — the company is using battery data it has collected from users’ devices to understand trends and make predictions for when it should lower the power draw of certain applications or features.”

He goes on to say that the “people with knowledge of the matter” spoke about a lock-screen indicator. This should intelligently be able to show just how long it will take to charge up the device back to full.

This all makes sense following rumours of the iPhone 17 Air potentially having battery life issues due to its slimmer form.

Gurman points this out directing saying: “The driving force behind the battery feature is the company’s upcoming slimmed-down iPhone 17, which will be offered as an alternative to the standard and Pro models. Because of its thinner design, the new iPhone will have a much smaller battery — and fewer hours of life than other models.”

Since this is an iOS 19 feature it may well apply to iPads too, as well as older iPhones. Although since this is part of Apple Intelligence, it will only work on devices capable of supporting that – so iPhone 15 Pro Max or newer.

I picked four wireless chargers so you can stop making your iPhone, AirPods, and Apple Watch fight over one dorm outlet

The best back-to-school wireless chargers for dorm desks, study spaces, and travel

Computer, Electronics, Laptop

A dorm-room desk can disappear surprisingly quickly beneath a laptop charger, phone cable, Apple Watch puck, and the growing collection of adapters required to power them all. Add textbooks and other academic materials, and finding enough room to study becomes the first assignment of the semester.

A wireless charging stand can consolidate several of those cables into one station. It also gives your phone a dedicated place to sit, which helps when you are checking the time or watching a lecture. Every charger here still needs one connection to the wall. So finding a peripheral that works with all of your gadgets isn't just convenient, it's smart. I picked four models ranging from an inexpensive two-device stand to a fast 25W wireless charger capable of powering an entire Apple setup.

Your backpack needs one of these power banks before classes start

I picked 4 power banks that can survive your longest day on campus

Anker Nano 3-in-1 10,000mAh portable power bank for iPhone.

Finding an empty outlet on campus can require more patience than registering for a popular class. Common spaces like libraries or lecture halls rarely have sockets in the right places. So a good power bank gives you far more freedom. It gives you the option to choose the quiet corner of the library, work outside between classes, or even finish an assignment without worrying about your laptop's battery.

The right model depends on what you carry, since a phone needs far less power than a MacBook or gaming laptop. I picked four Anker power banks that cover everything from everyday phone charging to running several demanding devices at once.

The Minimal Phone 2 looks dramatically better than the original, and I’m genuinely here for it

Plastic is out, metal is in, and Minimal Phone 2's renders suggest the digital detox phone concept finally has the hardware to match its ambition.

Electronics, Mobile Phone, Phone

I've been following the Minimal Phone since its initial crowdfunding days. The first iteration had the right idea trapped inside the wrong body, I’d say. Plastic build, no 5G, an underwhelming camera, and e-paper ghosting that frustrated early adopters; all these issues kept the phone from reaching a wider audience.

Now, founder Armen Youssefian has posted what appears to be a 360-degree render of the Minimal Phone 2 on X, and from what I can see, the team has done its homework.
