EU's new battery law is forcing phone makers to bring back removable batteries

Starting February 18, 2027, every smartphone, tablet, and pair of wireless earbuds sold in the European Union will need a battery that a user can remove and replace with commonly available tools — no proprietary screwdrivers, no heat guns, no solvents to soften adhesive. The rule was approved back in 2023 as part of the EU's broader battery regulation, but it has taken until now, with the deadline sixteen months out, for phone makers to actually start redesigning hardware around it. The decade-long trend toward sealed, glued-shut phones is about to reverse, and not just in Europe.

This matters more than a typical regional compliance footnote because of how the phone industry actually operates: manufacturers overwhelmingly prefer a single global hardware design over maintaining separate production lines for different regulatory regions. When the EU forced USB-C on Apple in 2024, the company didn't ship a special EU-only iPhone — it switched the whole product line. The same economics apply here, and they are the reason this regulation will likely reshape phone design well beyond the EU's borders.

What the law actually requires

The regulation's language is specific: batteries in portable devices must be "readily removable" using tools that are commercially available, not proprietary to the manufacturer. If specialized tools are genuinely required, the manufacturer has to provide them for free or at a reasonable cost at the point of sale. This is a materially higher bar than "repairable with effort by a technician" — it's designed around an ordinary consumer being able to do the swap themselves.

The regulation also sets a durability floor that is arguably the more disruptive part of the rule: batteries must retain at least 80% of their original capacity after 1,000 full charge cycles. Most phone batteries on the market today are only rated for 500 to 800 cycles before falling below that threshold — meaning manufacturers can't simply bolt a removable panel onto their current battery chemistry and call it compliant. The cells themselves need real improvement in cycle life, not just the mechanical housing around them.

Apple's narrow exception, and why it isn't really an escape hatch

The regulation includes a conditional exemption: a device can skip the removable-battery requirement if the manufacturer can demonstrate the battery hits 1,000 cycles at 80% capacity retention (or 800 cycles at 83%) and the device carries an IP67 water-resistance rating or higher. Apple, whose recent iPhones already claim IP68 ratings, is the company most obviously positioned to try to use this path.

But the exemption isn't free. Apple would still have to prove the cycle-life claim through EU-recognized testing, and doing so publicly invites exactly the kind of independent battery-degradation scrutiny that consumer publications have been running informally for years. Given that most real-world usage patterns degrade batteries faster than lab conditions, betting the entire compliance strategy on a cycle-life claim carries real reputational risk if third-party testing disagrees. It's a viable strategy, but not an obviously safer one than just building a removable battery.

The actual engineering problem: waterproofing versus access

The reason batteries got glued in during the 2010s wasn't primarily cost-cutting — it was water resistance. A screw-and-clip battery door is a gasket problem; a fully sealed unibody design solves waterproofing by removing openings altogether. Manufacturers now have to solve both problems at once, and the emerging answers borrow from designs that already exist in ruggedized and modular phones: electric-release adhesives that debond cleanly with a low-voltage pulse instead of requiring heat or solvent, single rear-panel removal systems with a dedicated waterproof seal (similar in spirit to older removable-back designs, but engineered to modern IP standards), and battery compartments isolated from the main board so a seal failure at the battery door doesn't expose the rest of the device.

None of these are exotic technology — they exist in various forms already. What's new is the incentive to ship them at flagship volume rather than as a niche "repairable phone" feature for a small enthusiast market.

What this means for buyers between now and 2027

Expect phones announced through most of 2026 to still ship with the current sealed designs, since product cycles that far along are already locked. The redesign will show up first in devices launched for the European market in late 2026 and early 2027, ahead of the hard deadline, and then propagate to global variants over the following product cycle as manufacturers consolidate designs. Phones marketed heavily on thinness may be the last holdouts, since a swappable battery compartment and a waterproof seal both add a small amount of internal volume that thin designs have spent a decade eliminating.

Takeaways

• If your next phone purchase can wait until 2027, you'll likely get meaningfully better battery longevity as a side effect of this rule, regardless of whether the specific unit is EU-market or not.
• Watch for manufacturers loudly advertising "up to 1,000 cycles" battery health — that number exists because of this regulation, not because of a voluntary industry improvement.
• Be skeptical of any flagship that claims the IP67+/1,000-cycle exemption without independent cycle-life verification; treat it as a claim to check against third-party battery-health testing after launch, not a guarantee.
• If repairability matters to you, 2027 model years are the ones to compare on ease of battery replacement — the regulation gives you a hard floor to measure every manufacturer against.
