Phones with 7-day battery life are actually coming soon, says fuel-cell maker

Despite all the amazing advancements we’ve seen with smartphone technology in recent years, we’re still left asking, “So what about battery life?” If it’s ever been a serious issue for you, chances are you’ve settled on a solution by now, whether it’s carrying around a portable charger, housing your phone in a bulky battery case, or occasionally diving into Starbucks to use a one of its wireless charging stations.

These options, while certainly useful, of course aren’t ideal. While plenty of tech firms are trying their hardest to develop more powerful battery technology, UK-based Intelligent Energy claims it’s taken some big strides, creating a breakthrough fuel cell small enough to fit inside a smartphone yet powerful enough to keep it running for a full week. And it could be rolled out within two years.

One unnamed “emerging” smartphone maker is so convinced by Intelligent Energy’s technology that it’s backing its continued development to the tune of $7.6 million, Bloomberg reported Monday.

Commenting on its work, Intelligent Energy’s Julian Hughes said, “We believe embedding fuel cell technology into portable devices provides a solution to the current dilemma of battery life and with consumers demanding more and more from their phones, battery innovation has not kept up.”

Hughes said his firm offers “a solution that is clean and efficient and means consumers could be truly mobile and free from the constraints of the grid.”

The environmentally friendly fuel cell technology creates power by combining hydrogen and oxygen. Curiously, a number of reports over the last two years suggested Intelligent Energy was working closely with Apple on a similar technology, though any partnership has never been confirmed.

The British technology company is also known to have developed a prototype fuel cell solution based on an iPhone. Speaking to the Telegraph last year, Intelligent Energy CEO Henri Winand said his engineers “managed to make a fuel cell so thin we can fit it to the existing chassis without alterations and retaining the original battery.”

The only design change required was the addition of some tiny vents on the back of the phone to allow waste water vapor and heat to escape.

Pulling all the reports together, it seems Intelligent Energy has pretty much nailed the technology, and appears to now be in the process of refining it prior to commercialization.

“With consumer power demands increasing and the advent of the ‘Internet of Things’ making the world more connected than ever, now is the time to address the biggest limitation we have in achieving true connectivity – battery life,” Julian Hughes said. Let’s hope Intelligent Energy can soon deliver on what it seems to have been promising for a while now. We’ll certainly all thank it if it does.

There’s a big problem with the iPhone’s Photos app

While my primary device these days continues to be my iPhone 15 Pro, I’ve dabbled with plenty of Android phones since I’ve been here at Digital Trends. One of my favorite brands of phone has been the Google Pixel because of its strong suite of photo-editing tools and good camera hardware.

Google first added the Magic Eraser capability with the Pixel 6 and Pixel 6 Pro, which is a tool I love using. Then, with the Pixel 8 series, Google added the Magic Editor, which uses generative AI to make edits that wouldn’t be possible otherwise. There are also tools like Photo Unblur, which is great for old photographs and enhancing images that were captured with low-quality sensors.

The Honor V Purse is the most unusual foldable I’ve ever used
Honor V Purse with its chain case.

The novelty factor of a foldable gets me excited every time I use a fold or flip phone. After all, there’s a big screen that’s being halved to fit inside my pocket, and depending on the phone, sometimes it’s made of thin glass! While foldables brought the fun factor back to phones, the Honor V Purse is bringing the same fun/exciting feeling to foldables.

I didn’t think things could get any better, but then I unboxed the Honor V Purse — and it has exceeded my expectations. It’s a reverse book-style foldable, meaning there’s a large portion of the screen that’s always exposed. I expected it to wear out within weeks, but I’ve had the device for a few months now, and after using it as my primary phone for three weeks, I’m amazed at how it has held up. It's durable, unique, and one of the most unusual folding phones available in 2024.
The Honor V Purse is one of a kind
