Is the used iPhone 15 Really More Sustainable? Here’s What Apple’s Environmental Report Reveals

At Used Mobiles 4 U, we’ve always encouraged people to consider the environmental impact of their tech choices. With each new iPhone release, there’s always a lot of buzz around the features—but what about the footprint it leaves behind?

Apple recently released its Environmental Progress Report for the iPhone 15, and we thought it was worth taking a closer look. Has the company made genuine strides towards sustainability? Or is it more clever marketing than meaningful action? Here’s what we found.

A Push Towards Recycled Materials

Apple’s been talking a lot about its use of recycled materials lately, and the iPhone 15 is no exception. According to the report, 100% of the cobalt in the iPhone 15’s battery is recycled. That’s a big step forward considering how controversial cobalt mining can be, particularly regarding labour and environmental concerns.

We’re also seeing recycled aluminium in the enclosure, along with recycled copper in the main logic board. In fact, Apple claims that over 99% of the tungsten used in the iPhone 15’s Taptic Engine is also recycled.

This sounds impressive, and to be fair, it is. Recycled metals require far less energy to process than mined ones. It’s great to see a shift like this, but we do think it’s important to ask how much of the overall phone these materials make up. Apple doesn’t always break that down clearly.

If you’re considering making an eco-conscious upgrade, a used iPhone 15 gives you access to these improvements without buying brand new.

Packaging: Less Waste, Fewer Plastics

The packaging for the iPhone 15 is 100% fibre-based, meaning it no longer contains any plastic components. It’s also designed to be smaller and lighter, which allows Apple to ship more units per delivery—cutting down on transport emissions.

We’re pleased to see this kind of change. Packaging is one of those areas where big companies can make a real difference, and fibre-based materials are much easier to recycle than plastics. Still, while it’s a step in the right direction, we believe the product inside the box is what matters most.

A used iPhone 15 from us at Used Mobiles 4 U usually comes with minimal packaging, further reducing environmental impact.

Energy Efficiency and Carbon Footprint

Apple reports that the iPhone 15 uses 56% less energy than the energy efficiency standard requires. The new chip is designed to consume less power, which means longer battery life and lower energy use during charging.

However, let’s not forget about the bigger picture. Manufacturing smartphones is still a carbon-heavy process. While the iPhone 15’s life-cycle carbon footprint is slightly lower than that of previous models (about 66 kg CO₂e per device), it’s still a considerable figure.

What does that number mean in practical terms? It’s roughly equivalent to driving a petrol car for around 160 miles. And that’s per phone. Multiply that by the millions of units sold each year, and the impact quickly adds up.

That’s why buying a used iPhone 15 makes more sense if you’re serious about reducing your own digital carbon footprint.

Repairability: A Bit of Progress

Repairability has always been one of the key issues when it comes to sustainability in tech. If something breaks on your phone, can it be easily and affordably fixed—or are you expected to replace the whole thing?

Apple has made some small strides here. The back glass of the iPhone 15 is reportedly easier to replace, which is a positive step. The company also continues to offer genuine parts for repairs through authorised centres and self-service repair programmes.

But from our perspective, this still doesn’t go far enough. Repairs can be expensive, and for most people, it’s still easier to just buy a new phone. That’s why we believe in offering high-quality refurbished iPhones, including the used iPhone 15, as a better alternative—both for the environment and your wallet.

Designed to Last… But for How Long?

Apple says its devices are built to last, and that’s partially true. The iPhone 15 comes with durable materials, a ceramic shield front, and water resistance. But longevity isn’t just about how long a phone physically survives—it’s about how long it stays useful.

The real issue lies in software support. Typically, iPhones receive updates for about 5–6 years. That’s better than many Android brands, but it still leaves a lot of perfectly functional devices behind. Once software support ends, apps stop working properly, and security becomes a concern.

In other words, you might not need a new phone, but you’ll feel like you do.

That’s one of the reasons we’re so passionate about offering the used iPhone 15. Not everyone needs the newest model. A gently used version of Apple’s latest handset can offer top-tier performance without the guilt of buying new.

Apple’s Climate Goals: Bold or Unrealistic?

Apple continues to tout its ambitious climate goals. The company wants every product to be carbon neutral by 2030. While this sounds good, we need to ask how this will be achieved.

A large portion of Apple’s “carbon neutral” approach hinges on carbon offsets. That means paying for things like tree planting or renewable energy projects to “cancel out” emissions. The problem is, offsets aren’t a perfect solution. Real carbon reductions should come from cutting emissions at the source—not just balancing the books.

Apple is investing in renewable energy for its suppliers, and that’s a big move. But as long as new phones are being manufactured in the tens of millions, it’s hard to argue that the approach is entirely sustainable.

The better choice? Avoid contributing to fresh production and opt for a used iPhone 15 instead.

The Sustainable Choice? Buy Refurbished

So, is the iPhone 15 more environmentally friendly than previous models? Yes, in some areas. The use of recycled materials, energy efficiency, and improved packaging are all steps in the right direction. But it’s not the green revolution some might hope for.

The most sustainable phone is still the one that’s already been made.

At Used Mobiles 4 U, we believe buying refurbished is one of the best ways to reduce your environmental footprint. When you choose a used iPhone 15, you’re not only saving money—you’re keeping another device in circulation and cutting down on unnecessary manufacturing.

And unlike some second-hand retailers, we only sell phones that have been fully tested, cleaned, and backed by a warranty for peace of mind.

Whether you’re upgrading your old model or switching from Android, a used iPhone 15 can offer you the latest Apple features without the environmental baggage.

Final Thoughts

Apple’s environmental improvements with the iPhone 15 are promising, but they don’t replace the need for more mindful consumption. No matter how many recycled materials are used, producing millions of new phones every year still leaves a sizeable carbon footprint.

If you’re serious about sustainability, consider whether you really need the latest model—or whether a high-quality used iPhone 15 could do the job just as well.
