Somewhere in a drawer you have a phone that works perfectly except for the part that stores electricity. It is not broken. It is just tired, sealed shut with glue, and waiting for a repair that costs more than it is worth. From 18 February 2027, the European Union wants that drawer to stop filling up.
The short answer: the EU Batteries Regulation requires that portable batteries in products sold in the EU be readily removable and replaceable by the end-user, using ordinary tools, with no glue to heat, no solvents and no software locks. Phones have an even earlier, stricter set of rules that already applies. Neither says every phone must have a 1990s pop-off back cover, and that is where most headlines go wrong.
What the regulation actually requires
Article 11 of Regulation (EU) 2023/1542 is short enough to read in full, which is rare and refreshing. The text is on EUR-Lex. The key points:
- Who: anyone placing a product with a portable battery on the EU market. It covers the whole battery, not individual cells.
- What "readily removable" means: removable with commercially available tools, without specialised tools (unless supplied free with the product), proprietary tools, thermal energy or solvents.
- Instructions: removal and replacement instructions must be available permanently online.
- Spare batteries: available for at least five years after the last unit of a model is placed on the market, at a reasonable and non-discriminatory price.
- Software: "Software shall not be used to impede the replacement" of a battery with a compatible one. That is the sentence aimed at parts pairing.
- When: Article 11 applies from 18 February 2027, and it applies to units placed on the market from that date. The phone you already own is unaffected.
The derogations are narrow. Appliances designed for wet environments and certain professional medical devices may be built so that only an independent professional replaces the battery. Products that need a permanent connection for safety or data integrity can be exempt. The Commission can add categories by delegated act; a 2026 draft would add some wearables, but a draft is not a rule until it is in the Official Journal.
Phones are a special case, and already covered
Here is the part the summaries skip. The Commission's guidelines on Article 11, published as C/2025/214 and explicitly not legally binding, note that where another EU law sets specific battery rules for a product, that law takes precedence. For phones and tablets, that law is the ecodesign regulation 2023/1670, which has applied to new models since 20 June 2025. Read the guidelines and the ecodesign regulation.
The ecodesign rules for smartphones require, among other things:
- a battery that keeps at least 80% of its capacity after 800 charge cycles;
- a user-selectable option to stop charging at 80%;
- spare parts, batteries included, available to professional repairers until at least seven years after the model stops being sold;
- a battery that can be replaced by a layperson, or by a "generalist" with basic repair skills if the device meets stricter durability requirements.
So the realistic 2027 phone is not a phone with a flimsy clip-on back. It is a phone whose battery can be swapped with a screwdriver and a spudger from a hardware shop, following published instructions, using a battery that is sold for seven years and that the phone's software accepts. Glue that needs a heat gun is out. Screws are fine.
What this means if you do not live in the EU
Nothing in these regulations applies outside the EU market. In practice, phone makers prefer one design per model, so a battery that is replaceable in Lisbon is usually replaceable in Lucknow. But "usually" is doing work in that sentence. Spare-part availability and pricing obligations stop at the EU border, and the energy label with its repairability score is an EU label.
If you buy outside the EU, the useful move is to look for the same signals the law forces into the open: published repair instructions, a listed battery part at a stated price, and no warning that a third-party battery will disable features. Our e-waste decision guide covers what to do with the phone you are replacing.
A hypothetical repair, before and after
This is an illustration, not a report of a repair we performed.
| Step | Typical sealed phone today | Phone designed to the EU rules |
|---|---|---|
| Opening | Heat pad to soften adhesive, pry the back glass, hope | Remove screws or clips with commercially available tools |
| Instructions | Third-party teardown videos | Maker's own instructions, permanently online |
| Finding a battery | Marketplace listings of uncertain origin | Maker-supplied spare, available for years after sales end |
| After the swap | Possible "unknown part" warnings or disabled features | Software may not impede a compatible replacement |
What to watch for in 2027 marketing
- "User-replaceable" without instructions. The instructions are part of the obligation. If you cannot find them, the claim is thin.
- A battery price that makes repair pointless. The rule says reasonable and non-discriminatory. It does not define a number, so compare the battery price with the phone's resale value.
- Pairing by another name. Watch for features that degrade with a replacement battery. The software clause is the one most likely to be tested in court.
- Durability claims. 800 cycles at 80% is a floor for new EU phones. A maker advertising more is making a claim you can hold them to.
Our 2018 note on lithium battery chemistry explained why cells age. The 2027 rules do not stop ageing. They make the consequence a part you can buy instead of a phone you throw away. For day-to-day habits that slow the ageing itself, see our guide to the 80% charging limit, which is now also an EU-required setting.
Frequently asked questions
Does my current phone have to be changed?
No. The requirement applies to products placed on the EU market from 18 February 2027. Existing phones are not affected.
Will phones lose water resistance?
The regulation's wet-environment derogation is for appliances meant to be washed or immersed, not ordinary phones. Phone makers must meet the ecodesign rule's dust and splash protection while keeping the battery replaceable. Screws and gaskets can do that; adhesive that needs heat cannot.
Can I still use a repair shop?
Yes. End-user replaceability is a floor, not a ban on professionals. The ecodesign rules separately require spare parts for professional repairers.
What about laptops, earbuds and smartwatches?
Laptops fall under Article 11's general rule. Earbuds and watches are the categories most discussed for derogations because of their size and sealing; check the Official Journal for what has actually been adopted rather than what has been proposed.
Research note — 21 October 2026: Based on the text of Regulation (EU) 2023/1542 Article 11, the Commission's guidelines C/2025/214 and Regulation (EU) 2023/1670, all read on EUR-Lex on 21 October 2026. The repair comparison is a hypothetical illustration, not a performed repair. Legal interpretation is for the Court of Justice of the EU; this article explains the rules in plain language and is not legal advice.
