As soon as upon a time — by which we imply the ’90s and early 2000s — when you wished to swap out your cellphone’s battery for a brand new one, all you needed to do was slide the again casing open and pop the battery out. The rise of modern however impenetrable smartphones largely noticed an finish to user-replaceable batteries. However now, within the mid-2020s, the tide could possibly be turning as soon as once more.

Two separate items of right-to-repair laws working their method by way of the European Union establishments — one among which was handed by the European Parliament on the finish of June — may drive cellphone producers to make vital adjustments to the best way they design telephones. As soon as they arrive into drive (anticipated to be in 2025 and 2027, respectively) they are going to put in place rules that compel makers of telephones and different small gadgets, like transportable sport consoles, to permit folks to exchange the batteries themselves.

As a smartphone proprietor, you may seemingly be accustomed to the particular frustrations batteries pose — specifically the drop-off in most capability over time and the lack to cheaply and simply do something to repair it. In the event you had been capable of swap the battery out, you would properly find yourself retaining your cellphone for a chronic interval.

“Battery degradation is a serious motive for contemplating an improve,” stated CCS Perception Chief Analyst Ben Wooden over electronic mail.

More and more cellphone producers similar to Apple, Samsung and HMD, which makes Nokia telephones, try to make their gadgets extra simply repairable at house. Because the begin of this 12 months, HMD has launched two telephones through which the batteries might be shortly changed by the proprietor, though it does require an iFixit toolkit to take action. Repairing smartphones has largely been a specialist job. However with extra energy to repair gadgets, the hope is that you’re going to be much less prone to discard them in favor of newer fashions, decreasing the general quantity of digital waste that comes from damaged or ageing merchandise.

“By empowering shoppers with the flexibility to exchange a worn-out battery themselves, it signifies that they will hold maintain of their gadget for longer,” stated Lars Silberbauer, chief advertising and marketing officer at HMD, which welcomed the EU’s proposals on user-replaceable batteries. “It additionally makes repairing a smartphone extra reasonably priced.”    

However abiding by the brand new guidelines goes to imply having to resolve some tough engineering challenges for firms aiming to conform. One phone-maker, Fairphone, has pioneered making telephones with absolutely user-replaceable batteries and, as they instructed me, it is no straightforward feat. Extra on that under.

Any guidelines that do find yourself coming into drive round user-replaceable batteries will solely apply to telephones offered inside the EU. However there’s precedent for European regulation spurring tech firms to make adjustments that have an effect on their merchandise wherever they’re offered. A first-rate instance is the European mandate for common chargers (chargers that can be utilized throughout a whole gadget class), which was finalized in October 2022 and can come into drive subsequent 12 months. It is anticipated to trigger Apple to modify away from utilizing Lightning connectors for the iPhone to the extra widespread USB-C, discovered on nearly all Android telephones.

Apple and Samsung did not reply to requests for remark concerning the approaching rules.   

Nevertheless it’s affordable to assume that if Apple and different phone-makers are pressured to make gadgets that embody user-replaceable batteries for one market, they could additionally promote these gadgets elsewhere.

Making batteries replaceable

To know the challenges, in addition to the professionals and cons, of creating such a tool, I requested Fairphone — an organization that already makes a cellphone with an simply replaceable battery — what’s concerned.

To Miquel Ballester, Fairphone’s head of product growth and one among its founders, there’s nothing novel about with the ability to change a cellphone’s battery. As an alternative it is a alternative that producers have made as telephones have trended thinner and thinner, he stated. And whereas battery capacities have improved through the years, the fundamental chemistry that causes them to degrade over time has not. 

“That is a truth and that has not modified since we had the outdated Nokias that each one had the replaceable batteries,” he stated.

Fairphone already makes telephones with replaceable batteries.


Fairphone is not only a phone-maker. Its mission is to problem the electronics {industry} to create gadgets which are longer lasting and simpler to restore. The entire telephones the corporate has made are modular, to allow them to be taken aside and put again collectively by anybody. Even somebody like me, who has little expertise of electronics apart from some informal soldering, can do it — and I’ve.

However making a cellphone this fashion comes with compromises, as Ballester properly is aware of. Having a completely built-in battery that is glued right into a smartphone creates a really steady connection between the ability module and the opposite parts. A replaceable battery cannot boast the identical degree of stability, that means that the connection is extra prone to be interrupted if the cellphone is dropped or if a speck of mud finds its method onto the connector.

(In 2016, LG tried its luck with a modular cellphone, the G5, within the waning days of telephones with batteries you would take away. CNET’s reviewer famous that the G5’s detachable battery was probably the most interesting side of the design.)

Mud and water could be a drawback for modular telephones. The Fairphone 4, which simply arrived within the US, is the corporate’s first gadget to come back with a water-proof score, which at IP54 is decrease than most top-end fashions. (The iPhone 14 has an IP score of 68.) Ballester sees this as much less of a problem, on condition that most individuals change their telephones today not as a result of they acquired a bit moist, however due to the battery, the software program or a smashed display screen.

Replaceable batteries additionally reside in bulkier housing to make sure they will match their glued-in counterparts for robustness and reliability.

“It is advisable take into consideration the structure of the cellphone in another way, and it’s possible you’ll not have the ability to ship in these tremendous skinny ratios that we’re seeing available in the market,” Ballester stated. With the housing taking on extra space, phone-makers additionally must go for lower-capacity batteries, he added.

In different phrases, replaceable batteries may result in chunkier telephones with much less battery life. Regardless of this, the Fairphone 4 nonetheless supplies sufficient juice in a single cost to final a full day, based on Ballester. Not like the flagship telephones in the marketplace, it simply will not stretch to at least one and a half or two days, he added.

Challenges and guarantees

The apparent profit of getting a replaceable battery is that in case your current one is inflicting you points and never lasting the complete day, you may swap it out for a brand new one. However this depends on those self same precise batteries nonetheless being out there as much as a number of years after you have first purchased your cellphone.

Spare batteries cannot simply sit across the shelf ready for use, as they too will degrade over time. Persuading suppliers to maintain making battery replacements could be a problem, stated Ballester, because the volumes are sometimes too low. He is assured, although, that if replaceable batteries turned the norm for phone-makers, they’d be a lot simpler to pay money for.

On the different finish of the cellphone’s lifecycle, having a replaceable battery is vastly helpful within the recycling course of. Probably the most precious a part of a battery is the cobalt, which might be recycled, however usually is not because of the truth it is built-in into the cellphone. This implies telephones will likely be recycled of their entirety for the metals, with the cobalt being misplaced within the course of.

But when batteries are replaceable, they are often simply extracted from the telephones and recycled individually. Proper now, that is not taking place sufficient, stated Ballester. 

“The cobalt recyclers are struggling to have sufficient quantity to have a very good enterprise case from cobalt recycling, so we have to improve the quantity of batteries that return,” he stated.

Recycling batteries individually permits extra supplies to be extracted.

He hopes that extra telephones with replaceable batteries would bolster the quantity of cobalt recycling that may happen. Equally he hopes that as battery expertise continues to enhance, there will not have to be a dialogue concerning the quantity of power a replaceable battery can maintain in comparison with a set module.

For cellphone producers now eager about how they could make gadgets with replaceable batteries, maybe for the very first time, it is clear that some compromises could also be required alongside the best way. However with cross-industry effort, there are vital alternatives to beat the hurdles that firms like Fairphone are already going through head on. 

In doing so, they could simply guarantee the following era of telephones keep longer in our pockets and ease the stress on the planet within the course of.
