Bendable smartphones: Panasonic's new flexible battery may pave the way

Add as a preferred source on Google

It’s said that one day we’ll enjoy flexible smartphones rather than the solid bricks we use today, but in order for that to happen, there are a number of tech breakthroughs that we’ll need to see. For example, we’ll have to figure out a way to make batteries bendable.

Panasonic thinks it has come up with the solution. While still far from a consumer-ready product, the company has built a battery that’s 0.55-millimeters thick and able to bend as much as 25mm and twist 25 degrees. No, it’s not the foldable battery some were expecting, but it’s certainly a step in the right direction.

Perhaps even more important than the fact that the battery can bend is that it can withstand bending while still charging and providing power — something that todays lithium-ion batteries cannot do.

While cool, the batteries have a long way to go before we’ll see them in our devices. Panasonic has only built batteries with between 17.5mAh and 60mAh capacities, so if they were to be implemented in a product today, they would really only be able to power extremely low-power smart textiles or smart cards. Still, Panasonic says that it intends to continue developing the tech, so perhaps one day we’ll see it inside a bendable smartphone.

“Panasonic’s new flexible battery can withstand bending and twisting beyond the Japanese Industrial Standards for identification cards,” said the company in a blog post. “When used in card devices such as smart cards and card keys that work on batteries, as well as body worn-devices and smart clothing, this battery can retain its characteristics even if the device is frequently bent or twisted.”

Panasonic isn’t the only company developing bendable tech — Samsung is thought to be prepping a commercially available flexible display at some point in 2017.

Apple is investigating cracked screens on the iPhone Duo and replacing broken units
Apple assures that not all units of the iPhone Duo are affected by the display issue.

Merely days after the iPhone Duo hit the shelves, images of broken screens on the phone started popping up across social media. Until now, it’s been unclear what’s causing the line of defective pixels that appears vertically along the crease, as well as horizontally, on the phone’s inner display.

Apple has finally acknowledged the issue, which has shown up on iPhone Duo units owned by customers as well as demo units in stores. In a statement shared with Bloomberg, Apple says that not all iPhone Duo units are affected and that those that are tend to show the display fault early on. The company added that users who experience problems with their iPhone Duo display should contact AppleCare for a replacement.

Apple quietly hopes to end the gizmo right-to-repair war. The iPhone Duo is the latest specimen.
The right-to-repair movement has entered its fine-print era.

Not long ago, Apple treated independent repair like an act of outright hostility. The Cupertino giant locked down parts with serial-number pairing, while repair tools remained firmly out of reach of anyone outside its authorized repair network. More importantly, the company waged a legal and lobbying battle against right-to-repair legislation.

I've covered enough of these fights over the years to know what a shift looks like. That's why what happened in October 2026 genuinely caught me off guard. The day the iPhone Duo went on sale, what may be the most mechanically complex iPhone to date, Apple pulled off a surprising about-face. It published teardown-style repair manuals for a handful of major components.

iPhone Duo is here. Let’s take a moment to appreciate the Galaxy Z Fold 8 and all the things it didn’t break
The Galaxy Z Fold 8 is not without its flaws, but in the face of the iPhone Duo, I have discovered more appreciation for it.

Apple's first foldable phone is now on shelves, in short supply, but with an unreal amount of buzz around it. After all, it's the first foldable iPhone, and there's plenty that this phone gets right. But there's also a lot that is either broken or underwhelming. What's peculiar is the dialogue around this phone, and how it has completely overshadowed every other attempt at making a phone with a similar form factor.

I've spent some time with the iPhone Duo, and I've used the Galaxy Z Fold 8 for almost three months now. In my opinion, Samsung deserves more credit. When the Galaxy Z Fold 8 arrived earlier this year, it was celebrated in some circles and ridiculed in others for supposedly copying what Apple would eventually deliver with the iPhone Duo. The dialogue was pretty odd, for multiple reasons. Samsung has been making foldable phones for years, so claiming that it copied a product Apple hadn't even launched was simply absurd.
