Ecodesign requirements will apply to mobile phones and tablets put on the EU market from 20 June 2025 onwards, including:

1. resistance to accidental drops or scratches and protection from dust and water
2. sufficiently durable batteries which can withstand at least 800 charge and discharge cycles while retaining at least 80% of their initial capacity
3. rules on disassembly and repair, including obligations for producers to make critical spare parts available within 5-10 working days, and for 7 years after the end of sales of the product model on the EU market
4. availability of operating system upgrades for longer periods (at least 5 years from the date of the end of placement on the market of the last unit of a product model)
5. non-discriminatory access for professional repairers to any software or firmware needed for the replacement
