The Takeaway
Under pressure from European regulators, Apple is exploring a new method to make iPhone battery replacement easier, potentially reducing electronic waste.
Under pressure from regulators in Europe and elsewhere, Apple in recent years has taken small steps toward making the iPhone easier for consumers to repair. But self-repair remains a cumbersome step for consumers—particularly when it comes to battery replacement.
Under a law passed by the European Union last year, phone makers have to ensure smartphone batteries can be replaced by their owners with easily accessible tools by 2025. With that in mind, Apple is exploring the use of a new technology to make battery replacement a little easier for consumers, according to five people involved in the iPhone’s manufacturing.
If successful, Apple would use the new method in at least one model of the iPhone 16 this year and possibly all versions of the iPhone 17 slated for global release next year, according to the people. But the new method—which uses electricity to dislodge the battery—will still be too complicated for most people.
An Apple spokesperson declined to comment.
The iPhone currently uses adhesive strips to hold the battery in place. To replace the battery, people must pull on these strips with tweezers to dislodge it and install a new battery using a specialized machine and tray that presses it in place. If a consumer breaks the strips while pulling them, they need to apply heat or a solvent such as rubbing alcohol to dislodge the adhesive.
The new technology—known as electrically induced adhesive debonding—involves encasing the battery in metal, rather than foil as it is currently. That would allow people to dislodge the battery from the chassis by administering a small jolt of electricity to the battery, the people said.
Consumers still have to pry open the iPhone themselves, which is not an easy process because of the adhesives and screws that keep the iPhone’s screen sealed in place.
Apple will still recommend consumers use repair professionals for battery replacement given the need to apply a low voltage to the battery to dislodge it and attach a new one, one person with direct knowledge of the process said.
“I’d love to see Apple innovate toward improved repairability,” said Kyle Wiens, CEO of iFixit, a gadget repair website. “Glue is the bane of modern device repair, and any strategies that help reverse adhesives are welcome.”
Wiens said applying a voltage to release the iPhone battery is a promising approach, as direct current power supplies—typically used for electronics testing and charging—are widely available for purchase.
Many people choose to upgrade their phone when they see the battery dying, even though Apple for many years has offered a battery replacement service, now costing $99.
Expensive and Complex
Although early mobile phones had batteries that could be swapped in and out by hand, the rise in popularity of the iPhone and other smartphones—coupled with the invention of longer lasting mobile batteries—ushered in a new era where removable batteries took back seat to a desire for better water resistance and thinner designs. This required the devices to be tightly encased using adhesives and seals, making them difficult to open for consumers.
In 2022, Apple introduced self-repair options, as part of its efforts to comply with a wave of new right-to-repair laws across the world. Consumers can buy replacement parts from Apple and rent equipment that allows them to fix their iPhones without a professional, although the tools and rentals were still prohibitively priced and bulky.
For instance, consumers can buy a battery they can install themselves for $51.48—and rent the specialized tools needed to replace it for $49. That means there is no financial advantage for consumers who want to do it themselves. It’s unclear how those prices could change if it adopted the new technology.
On Wednesday, Apple announced that its repair software for helping users diagnose problems with their devices would be available to 32 European countries after it was made available to the U.S. only last year. It also released a whitepaper spotlighting its repairability efforts, saying that it was “committed to designing all products with serviceable batteries.”
The fact that Apple is testing a new battery replacement technology suggests it feels the pressure of the new European law. That law was the latest in a series the EU has enacted requiring Apple and other tech firms to redesign their software and hardware to be more open and consumer friendly.
The EU already has mandated that Apple must offer alternative app stores and give outside payment services access to its hardware.
Possible Exemption
Apple could be exempt from the EU’s battery replacement law if the iPhone can fulfill three requirements. Those require that batteries retain at least 83% of their capacity after 500 full charges and 80% of their capacity after 1,000 full charges.
The device also needs a water and dust resistance rating of at least IP67. The iPhone has had that rating, or higher, since 2016 but only recently met the battery health criteria for 1,000 full charges with the iPhone 15. Apple didn’t reveal the battery health of the iPhone 15 after 500 full charges but the iPhone 14 and earlier models wouldn’t have met the 500-charge requirement, according to its disclosures earlier this year.
There have been some signs that Apple is working on electrically induced adhesive debonding. In November, a user on X posted photos of what they claimed was the battery for the iPhone 16 Pro. The component had a metal shell for the first time, which is a prerequisite for the bonding process to work.
Last year, Apple’s senior vice president of hardware engineering, John Ternus, said in an interview with a German YouTube channel that there were trade-offs to complying with the new European battery replacement law. If users can easily take apart their phones, that could make the iPhone less water resistant.
“We absolutely believe that if people need a battery replacement, there should be a safe and an effective way to do that, and we’ve been enabling that through various Apple Stores and also our service partners,” he said. “We always need to make sure we’re balancing the durability with that repairability.”
