The EU Just Waived Its Battery Rules for Smart Glasses. That Is Not the Regulation Meta Should Be Worried About.

On July 14 the European Commission adopted a delegated act that quietly removed one of the more awkward engineering problems facing every smart glasses maker selling into Europe. Smartphones sold in the EU will soon have to ship with batteries that customers can remove themselves. Wearables will not, and the Commission has now written smart glasses into that carve-out explicitly, alongside smartwatches, fitness trackers, and electric toys.

For anyone building a product that has to sit on a human face for eight hours, this is not a small thing. A user-serviceable battery door means a seam, a latch, and a tolerance stack, and all three cost you grams and millimeters in a product category where grams and millimeters are the entire competition. The practical read is that Meta, Google, Samsung and Apple can now sell essentially the same hardware in Frankfurt that they sell in Fort Worth.

What the exemption actually does, and what it does not

It is worth being precise here, because the headline version of this story is wrong in a way that matters. The Commission did not exempt smart glasses from repairability. It exempted them from end-user battery removal. Those batteries still have to be removable and replaceable by independent professionals, which means the third-party repair channel survives intact. What has been waived is the requirement that you, personally, at your kitchen table, be able to pop the cell out.

The Commission's stated reasoning leans on safety and physics rather than commerce. A spokesperson framed the act as a measure "to ensure safer consumer and industrial products in cases where opening a device could create safety risks or where technical limits make consumer access unrealistic," and stressed that it "is not about regulating one specific product."

On the technical-limits point, they have an argument. The battery in a pair of Ray-Ban Metas is a sliver of lithium tucked into a temple arm a few millimeters thick. There is no honest design in which a consumer swaps that in the field without a meaningful chance of puncturing a pouch cell next to their skull. Whether that argument justifies a category-wide exemption rather than a device-specific one is exactly what the next two months are about.

The pressure question

Politico reported the change as a relaxation that followed US pressure, and the sequencing does the framing no favors. The Commission's response was flat denial. It "has not given in to anyone's pressure," the spokesperson said, noting the proposals came out of "a broad public consultation with consumer associations, industry stakeholders and the Member States."

Consumer advocates are not buying the tidy version. Cláudio Texeira, head of digital policy at BEUC, Europe's largest consumer protection group, put it bluntly: "Europe should not dilute consumer protections. Smart glasses are already raising important concerns about privacy, security and consumer choice. Exemptions from EU battery removability rules should remain exactly that: genuine exceptions based on clear technical and safety evidence, not industry pressure. Exempting these devices ... risks setting a dangerous precedent."

The precedent worry is the sharp end of that quote. Battery removability was supposed to be a floor, not an opening bid. Once "the device is too small and too sealed" becomes an accepted reason to skip the floor, every product team in the category has an incentive to design toward the exemption rather than away from it. That is a durable change in engineering behavior, and it will outlast whoever is currently lobbying whom.

The act is not law yet. The European Parliament and the Council now have a two-month scrutiny window in which to object. If nobody does, it enters the Official Journal and takes force twenty days later, which puts the realistic in-force date somewhere around late November or early December.

The regulation that actually has teeth is still coming

Here is why I think the battery story is the smaller one. A battery exemption is a manufacturing convenience. It changes a bill of materials. It does not change whether you are allowed to operate.

The European Data Protection Board, which coordinates privacy regulators across the bloc, has commissioned a report into smart glasses that is expected to be finalized this summer. From there, EU lawmakers assess what to do. That is the process that decides whether a camera worn at eye level, pointed at strangers who never consented to anything, is a product Europe permits in its current form. Compared to that, a battery door is a rounding error.

The timing is not helping Meta's case. The company is already facing a class action in the US over its Ray-Ban smart glasses, built on allegations that private camera footage was routed to a subcontractor in Kenya for manual review to train AI models. Those allegations trace back to reporting by Sweden's Svenska Dagbladet and Göteborgs-Posten, which described workers reviewing and labeling images and video uploaded from the glasses. A European regulator reading that reporting while drafting a smart glasses privacy assessment is not a happy coincidence for anyone in Menlo Park.

So Meta and its competitors got the win they wanted this week, and it was a real one. Europe is a market you cannot skip, and shipping a separate EU SKU with a battery hatch would have been an expensive, ugly compromise. But the regulatory question that determines the ceiling on this category was never about batteries. It was always going to be about the cameras, and that answer is due in a few weeks.
