Where the data comes from
- EU database EPREL (European Commission): since 20 June 2025, manufacturers and importers enter the repairability class, index, battery, updates, drops and more for smartphones and tablets. These are supplier figures for which the suppliers alone are responsible; market surveillance authorities can check them.
- French indices (data.gouv.fr): repairability and durability index with scores from 0 to 10, as published by the companies placing the products on the market.
- Retailer feeds of our partner shops: prices, shipping, delivery time and photos only. They never affect scores or ranks.
Overall rating for smartphones and tablets
The overall rating is our own editorial rating with a disclosed method, not the official class on the energy label. Each factor gets 0 to 10 points on a fixed scale; the weighted sum is the overall rating.
Why we weight it this way
We weight each factor by how much it decides how long you can use a device. Repairability counts most, then how long the device stays up to date and the battery stays good. Robustness and everyday comfort count less because they rarely decide the lifespan on their own.
| Factor and reason | Weight | How the points are calculated |
|---|---|---|
| Being able to repair 45 % | ||
| Repairability index (EU)The official index already combines several repair criteria: disassembly depth, tools, fasteners, spare parts and repair information. Hence the largest weight. | 35 % | index 1 gives 0, index 5 gives 10 points, linear |
| User-replaceable batteryThe battery is the typical wear part. If you can replace it without a workshop, that is the simplest way to keep using the device. | 10 % | yes 10, no 0 |
| Staying usable for long 30 % | ||
| Software updatesWithout security updates a device can at some point no longer be used safely, even if the hardware still works. | 20 % | 1 point per year, 10 from 10 years |
| Charge cyclesShows how long the battery lasts before it noticeably weakens (cycles until 80 % capacity). | 10 % | 1 point per 200 cycles, 10 from 2,000 cycles |
| Robust in everyday use 25 % | ||
| Drop resistanceA drop is an everyday risk. A device that survives it does not need repairing in the first place. | 10 % | class A 10, B 7.5, C 5, D 2.5, E 0 |
| Battery life per chargeMore comfort than lifespan: long battery life per charge does not make a device last longer. | 5 % | 1 point per 10 hours, 10 from 100 hours |
| Dust and water protection (IP)Protects against damage from water and dust but rarely decides the lifespan on its own. | 5 % | dust 0 to 6 up to 3 points, water 0 to 8 up to 7 points (IP68 = 10) |
| Scratch resistanceScratches are annoying but rarely make a device unusable. | 5 % | Mohs level = points |
Example: a device with 8 points for the index and 6 points for updates gets 0.35 × 8 + 0.20 × 6 = 4.0 points from them; the other factors are added the same way.

Rankings by French index
For laptops, dishwashers, vacuum cleaners, TVs and washing machines we sort by the official French score. We do not calculate these scores ourselves.
Ranks and ties
- With equal overall ratings, the higher repairability index comes first, then the newer model (market start), then the name.
- Unusual figures marked “!” count at the category’s typical value, never more.
- Where class and index do not match, the index counts at most up to the limit of the registered class.
- A missing figure counts as 0 points.
Favourites
We pick favourites by fixed rules from the data, never for money, and only among devices with their own device page; each favourite is from a different brand. We say “favourite”, never “test winner” or “recommendation”.
Offers and money
- Rankings cannot be bought: they stay sorted by score whether or not there is an offer and whichever retailer has it.
- For some links we earn a commission if you buy (marked “Ad”). Your price stays the same. Offers for a device are sorted by price including shipping.
- In suggestions such as “Similar devices”, search and the alternatives without an offer, we show devices with an available offer first. Their scores do not change. In every ranking you can filter with “Offer available” yourself.
What we don’t do
- We do not lab-test devices or award test verdicts.
- We do not change official values. We flag unusual figures and count them cautiously (see the rules above).
- We take no money for ranks or ratings.
Updates and errors
We reload EPREL and the French datasets every week and prices every day. If you find an error, write to us via the legal notice; we correct it and note the change.
Texts written with AI support
The “assessment” on some device pages is written with AI support from the data on that page. Every figure in the text is checked against the data automatically when the page is built; if one does not match, the text is not shown.
Our own editorial rating with a disclosed method, not the official class from the energy label. The values come from the suppliers in EPREL (European Commission), who are solely responsible for them; the Commission does not endorse the ranking.
