Smartphones are built from a long list of materials, including metals, plastics, glass, batteries, and electronic components. Producing those materials and assembling a new phone also requires a significant amount of energy.
That means no new smartphone is completely impact-free. The better question is which phones are designed to reduce their impact through recycled materials, longer software support, better repairability, stronger durability, and more responsible end-of-life planning.
In many cases, keeping your current phone longer or buying a refurbished device is more sustainable than upgrading simply because a newer model is available. When a phone genuinely reaches the end of its usable life, EACR’s cell phone recycling services provide an appropriate option for unwanted devices.
What Makes a Cell Phone Eco-Friendly?
There is no single feature that makes a phone sustainable. The overall picture matters.
Recycled Materials
Many manufacturers are increasing the amount of recycled material used in their phones.
That can include:
- Aluminum
- Cobalt
- Lithium
- Copper
- Rare earth elements
- Plastics
- Glass
Using recycled materials can reduce the need for newly mined materials and give existing materials another use.
Repairability
A phone that can be repaired has a better chance of staying in service longer.
Replaceable batteries, displays, charging ports, cameras, and other common failure points can prevent a relatively small problem from turning into a full-device replacement.
Software Support
Hardware can keep working long after software support ends.
Long-term operating system updates and security patches help keep a phone usable, compatible, and secure for more years. That can reduce pressure to replace a device that still works physically.
Durability
A phone that survives everyday use is less likely to be replaced early.
Water resistance, stronger glass, replaceable components, and solid overall construction can all help extend the device’s useful life.
Packaging and Manufacturing
Sustainability also extends beyond the phone itself.
Recycled paper packaging, reduced plastic use, lower-carbon materials, and more efficient manufacturing can all reduce the environmental impact associated with producing and shipping a new device.
The Most Eco-Friendly Phones in 2026
Different phones take different approaches to sustainability. Some focus heavily on repairability, while others emphasize recycled materials, long software support, manufacturing, or worker practices.
| Phone | Sustainability Strength |
| Fairphone (Gen. 6) | Repairability, replaceable parts, long software life, recycled materials |
| Apple iPhone 17 | High recycled-material content and extensive use of recycled metals |
| Samsung Galaxy S26 | Broad use of recycled metals, plastics and battery materials |
| Google Pixel 10 | Recycled aluminum, high recycled content by weight, long software support |
| ASUS Zenfone 12 Ultra | Recycled aluminum, recycled glass, reduced packaging |
| Xiaomi | Strong worker score in this comparison, but weaker circularity and environmental results |
There is no perfect way to rank these phones because sustainability depends on what matters most to the buyer. Repairability, recycled materials, software longevity, manufacturing, worker practices, durability, and overall lifespan can all play a role.
#1. Fairphone (Gen. 6)
Fairphone continues to stand out because it is designed around repairability and long-term use.
Key sustainability features include:
- 12 user-replaceable parts
- Replaceable battery
- Replaceable display
- Replaceable USB-C port
- Replaceable back cover
- Spare parts planned through 2033
- Software support planned through 2033
- About 51% of the device by weight uses fair or recycled materials
- Recycled aluminum, copper, steel, indium, magnesium, nickel, plastics, rare earth elements, tin, and zinc
- Plastic-free packaging
- E-waste take-back program
Why It Stands Out
The biggest advantage is longevity.
If the battery wears out, the charging port fails, or the display breaks, the entire phone does not necessarily need to be replaced.
That kind of modular design can help keep the device in service longer and reduce premature electronic waste.
#2. Apple iPhone 17
Apple’s main sustainability strength with the iPhone 17 is its use of recycled materials throughout the device.
The standard iPhone 17 contains about 30% recycled material by weight, including:
- 85% recycled aluminum in the enclosure
- 100% recycled cobalt in the battery
- 95% recycled lithium in the battery
- 100% recycled rare earth elements in magnets
- 100% recycled gold plating in Apple-designed circuit boards
- 100% recycled tin solder in Apple-designed circuit boards
- 100% recycled tungsten in the Taptic Engine
Why It Stands Out
Apple is using recycled material in components that have traditionally depended heavily on newly extracted metals.
The bigger sustainability advantage, however, comes from longevity. An iPhone that stays in use for many years generally makes more sense than replacing it simply because a new generation becomes available.
#3. Samsung Galaxy S26
Samsung has expanded its use of recycled materials across a wide range of components in the Galaxy S26 series.
Depending on the specific model, Samsung reports the use of recycled:
- Plastic
- Aluminum
- Glass
- Rare earth elements
- Steel
- Copper
- Gold
- Cobalt
- Lithium
- Tantalum
The Galaxy S26 series also uses 100% recycled paper for its packaging box and is scheduled to receive seven generations of operating system upgrades and seven years of security updates.
Why It Stands Out
Samsung is spreading recycled content across many different materials instead of focusing only on the phone’s exterior.
That includes materials used in batteries, internal components, and circuit-board-related parts, giving the sustainability effort a broader reach across the device.
#4. Google Pixel 10
Google’s Pixel 10 is another strong mainstream option for buyers looking at sustainability.
Google says the phone:
- Contains at least 32% recycled materials by product weight
- Uses 100% recycled aluminum in the housing
- Comes in plastic-free packaging
Why It Stands Out
The Pixel combines recycled materials with long-term usability.
That matters because a phone’s environmental impact is not just about what it is made from. Keeping the device supported and usable for more years can also reduce the need for premature replacement.
#5. ASUS Zenfone 12 Ultra
The ASUS Zenfone 12 Ultra is worth considering as an alternative outside the largest smartphone brands.
Its sustainability features include:
- 100% recycled aluminum in the frame
- 22% recycled glass
- Reduced paper packaging
- A protective case made partially from post-consumer recycled material
ASUS also focuses on durability and battery management to help extend the phone’s useful life.
Why It Stands Out
The Zenfone 12 Ultra combines recycled construction materials with practical features designed around longevity.
Rather than relying on one sustainability claim, ASUS addresses materials, packaging, durability, and battery life together.
#6. Xiaomi
Xiaomi has a more mixed sustainability profile than some of the other brands on this list.
Its strongest result in the comparison is Fair Pay & Worker Respect at +40, the highest positive worker-related score among the brands reviewed.
At the same time, Xiaomi scores:
- -30 for Zero Waste & Sustainable Products
- -20 for Planet-Friendly Business
- -10 for Weapons
- -10 for Animal Welfare
- -10 for Community Impact
- -10 for Sourcing
- -10 for Safe Technology
Why It Stands Out
Xiaomi stands out more for its worker-related performance than for product circularity.
That creates a genuinely mixed picture. Buyers focused heavily on labor practices may view Xiaomi more favorably, while those prioritizing repairability, e-waste reduction, circular product design, or broader environmental performance may weigh the weaker scores differently.
Xiaomi also publishes climate, labor, supplier, and conflict-minerals information through its ESG reporting library.
Is Buying a New Eco-Friendly Phone Actually the Greenest Option?
Not necessarily.
If your current phone still works, keeping it longer may be more sustainable than replacing it simply to buy a newer model with better environmental claims.
Other options include:
- Repairing your existing phone
- Replacing the battery
- Buying refurbished
- Buying secondhand
- Passing your current phone to another user
Every new phone still requires materials, manufacturing, transportation, and energy. Extending the life of an existing device can reduce demand for new production and delay another phone from becoming e-waste.
What to Look for When Buying an Eco-Friendly Phone
If you do need a new phone, look beyond a single recycled-material percentage.
Important factors include:
- Long software support
- Replaceable or repairable components
- Recycled metals and plastics
- Battery longevity
- Durable construction
- Minimal or plastic-free packaging
- Manufacturer recycling or take-back options
The phone you can realistically keep for six, seven, or eight years may ultimately be more sustainable than one with impressive recycled-material claims that gets replaced after two.
What Should You Do With Your Old Phone?
If your old phone still works, consider keeping it in use.
Other options include:
- Reselling it
- Donating it
- Passing it down
- Trading it in
- Keeping it as a backup device
If the phone is genuinely at the end of its useful life, recycle it rather than leaving it in a drawer or treating it like ordinary trash.
Conclusion
There is no completely impact-free smartphone. Fairphone, Apple, Samsung, Google, ASUS, and other manufacturers are approaching sustainability in different ways through recycled materials, repairability, longer software support, better packaging, and more durable designs.
The most sustainable phone is often the one you can keep working the longest. When a device is damaged, outdated, or truly finished, EACR’s phone recycling services provide a responsible end-of-life option for unwanted phones and tablets.
