With environmental issues under the spotlight, we’re becoming increasingly aware of the damaging effects that mountains of textile and plastic waste our throw-away lifestyle generates. Hardly any of us realise the harmful side-effects of the millions of iPhones manufactured by Apple every year and our seemingly innocuous act of buying a new iPhone and tucking our old one away.
Without getting too deep into discussion about the intersection of technology with sustainability, let’s examine how bad iPhones are for the environment and whether Apple is taking the necessary steps to make iPhones environmentally friendly.
The main problem with iPhones, and smartphones in general, is their short lifespan. Annually, Apple takes to the stage to announce an ‘improved’ version of an iPhone and due to numerous factors including end of contracts, brand loyalty and physical damage to their current iPhones, many users will inevitably upgrade. In fact, 45% of smartphone owners would rather upgrade than repair their phone with cost of repairs being the main culprit.
Apple improve the specifications of their iPhones every year, but we are at a point where we should be seeing significant advances to reduce the environmental impact of smartphones. There are some scientifically agreed and established tactics that can be implemented to reduce the impact of iPhones on the environment:
Many of these are already incorporated into Apple's operations to some extent, and in comparison to other smartphone manufacturers, Apple is more environmentally focused. Apple retail shops and data centres are powered by 100% renewable energy and the tech giant uses an advanced recycling robot which takes 200 iPhones apart per hour. But this is only a fraction of what can be done, and the same ambition for accessible repair and planet-first hardware design from Apple is much needed.
Apple reports that 71% of its carbon emissions are generated by manufacturing and only 19% by use of products. Although Apple is taking measures to reduce the use of toxic and ‘critical’ materials in the production and the latest iPhones use 100% certified recycled gold in the plating of their logic boards, a closer look at Apple’s environmental reports demonstrates a trend of rising carbon emissions related to its flagship products, which covers everything from mining the raw materials to final assembly.
It’s not difficult to calculate that if iPhones were made to last, consumers could offset the emissions created during production by simply being able to use their iPhones for longer. But fragile designs and costly repairs encourage people to pick a new iPhone instead of keeping their current model for longer.
Remember the controversial Apple news of 2018? Apple was caught intentionally slowing down older iPhones in an attempt to prevent unexpected shutdowns. Fast forward to today, after various multi-million dollars lawsuits, Apple is now more transparent about their practices and users have an option to manually disable processor throttling on their iPhones. But the main concern remains, Apple building planned obsolescence into their devices which contradicts their claims of sustainability. This shouldn’t occur in a tech company’s operations that positions itself as doing good for the planet.
The glass design gives iPhones a premium feel, however "glass is glass and it breaks". It makes iPhones prone to scratches and unsightly cracks that are expensive to fix. Apple have added Ceramic Shield coating to its iPhone 12 series and carried it over to iPhone 13 lineup promising 4x better drop resistance. This improvement is applaudable, however the iPhone 12 still scratches at level 6. Various drop tests have reported better durability of iPhone 12 screens. But let us remind you that only the displays of iPhone 12 series are coated with Ceramic Shield technology. What is the point of protecting the front glass and leaving the rear one out of the equasion. This leaves us with an impression that Apple is making baby steps in the right direction, however what is claimed on stage during iPhone launches differs from real life products and it doesn't match up with Apple's ambitions towards sustainability.
Apple is doing a great job at keeping their devices supported for longer than its rivals do, and equips iPhones with performance enhanced processors. For example, a five year old iPhone 7 runs the latest iOS without an issue. But besides perfectly functioning software, the batteries naturally degenerate, and even though there are ways to maintain battery longevity, replacing a battery is sometimes essential, but can only be officially supplied by Apple and replaced by an Apple certified repair provider.
One of the main reasons for iPhone replacement is physical damage or an unhealthy battery. Apple charges substantial fees for repairs and actively opposes Right to Repair, making it challenging and nearly impossible to fit a new screen or swap a battery at home or do so at a local repair shop for a fraction of the cost. When weighing the cost of repair against the price of a new phone and factoring in the hassle of taking an iPhone for a repair or worse dealing with warning messages and disabled features, it is all too common that consumers decide to rather upgrade.
Apple takes measures to prevent unauthorised repairs. Simply swapping your iPhone's screen at a third-party repair shop will trigger a non-genuine display alert. As documented in a video by Phone Repair Guru on YouTube, Apple has gone one step further with the iPhone 13 series disabling FaceID after the display replacement, even if the screen fitted was from another iPhone. TheArtofRepair channel on YouTube was among the first to face a new ‘feature’ that Apple introduced: battery replacement in the newest iPhones triggers a warning message saying “Unable to verify this iPhone has a genuine Apple battery”. This disables the battery health analysis further damaging the longevity of the iPhone, unless the battery can be authenticated to the iPhone at an Apple store. Authentication can only be performed with Apple’s repair and calibration software which Apple has so far not made available to independent repair shops. The official communication is that Apple keeps control of this over fears of catastrophic battery failure.
If you have owned an Apple phone, it will come as no surprise that the cables break easily and it is likely that you have had at least double the amount of charging cables. Apple charging cables are a nightmare for consumers. With daily use, cables fray and the contacts start to wear off, and the cost of £19 per cable over the course of owning an iPhone adds up fast. However, from a design perspective they are sleek, simple and follow the design-first directive that is fundamental to Apple.
The iPhone maker has rejected the recent EU proposal to introduce universal chargers for smartphones. Apple’s opinion on common charging cables is that they stifle innovation rather than encourage it, and would harm consumers in Europe and the economy as a whole. Undoubtedly, MagSafe chargers and the whole idea of having a port-less iPhone one day, is Apple's way of working around the upcoming regulations. We interpret Apple's position on this as millions of dollars that Apple is making in revenue by selling poor quality chargers is an obstacle Apple is not ready to overcome to reduce e-waste, which is another contradiction to maintaining a healthy environment.
Apple have also made a decision to no longer supply charging bricks with iPhone 12 series and positioned this move as an effort to fight the growing amounts of e-waste. If you have previously owned an iPhone, you most likely have a charging adaptor, but their's a caveat. Only iPhone 11 charging bricks are compatible with the iPhone 12 series, and unless you're upgrading from an iPhone 11, you will need to spend additional money to buy the adaptor which will come in its own packaging, has its own carbon footprint and needs to be delivered to you separately. We don't need to do any advanced math to conclude that this green move by Apple does more harm than good.

Over the past few years, scientists, environmental organisations and climate activists have been pushing for a change in consumer behaviour and encouraging corporations to implement environmentally ethical practices. While we see many iPhones being traded in and given a second life through Compare and Recycle and Apple cares about the environment to some extent, at a global scale every manufactured iPhone continues to harm the environment.
With Apple's resources, iPhones have the potential to be the most ethical smartphones. Currently, there’s no 100% green way to buy a new iPhone, but we can change our behaviour and stick to the greenest smartphone: the one you currently own. If you genuinely need a new phone, follow our advice on how to upgrade with less impact on the environment.
Looking for an eco-friendly case for your iPhone or Android? We’ve reviewed various phone case brands to find out what are the best eco-friendly phone cases and here are our six recommendations for ethical smartphone cases and where to buy them.
Apple has announced the launch of the Self Service Repair program which is rolling out from 2022 in the US and expanding into other countries later that year. Is the long fought battle over Right to Repair coming to an end? That’s definitely something every repair advocate is thinking right now, but while it’s a bit early to celebrate victory, it is undoubtedly a fantastic first step from Apple and it is going to be a brilliant initiative if Apple do it right.
Repairing a broken phone can be a costly affair, but it is definitely worth it from environmental standpoint. If you're considering a mobile phone repair, comparing repair options is crucial to make sure you're getting the right service for your money. In this article we explore repairs of common smartphone damages and guide you through repair options available to you.
