Wireless charging has been around for years. promise that never quite took off: Comfortable, yes, but slower, inefficient and full of nuancesIn 2025, the script changes dramatically: the Wireless Power Consortium (WPC) has officially approved Qi2 at 25 W, opening the door to mass adoption on Android that aims to bring order where there was previously fragmentation.
The leap is not minor: Going from 15 to 25 watts increases power by around 67%., significantly reducing wait times and improving efficiency thanks to magnetic alignment. Additionally, for the first time, the Android ecosystem is aligning with the magnetic approach popularized by MagSafe on iPhone, paving the way for a single charger to serve both worlds without any speed restrictions.
What is Qi2 25W and how did we get here?
Qi2 25W is the direct evolution of the initial Qi2 standard: What was known as Qi 2.2 is now commercially available as Qi2 at 25 W.The key innovation is the increase in power compared to the original 15 W, which is complemented by efficiency improvements by ensuring proper alignment between coils using magnets.
The differential piece is the use of the Magnetic Power Profile (MPP), inspired by Apple's MagSafe ecosystem. This system uses a ring of magnets to "stick" the phone to the base in the optimal position, avoiding the typical power loss caused by improper placement that hampered previous generations.
From the initial Qi2 to Qi2 25W: why it matters now
The original Qi2 brought magnetic attachment and a 15 W ceiling. It was a step forward, but not enough to compete head-to-head with wired charging. The upgrade to 25W changes the equation: it speeds up, improves consistency, and makes it feasible to think about the unification of chargers between iPhone and Android.
The WPC is not just about more power; its goal is end fragmentationUntil now, many Android devices have relied on proprietary protocols (and dedicated chargers) to achieve high wireless speeds, while the experience with standard Qi has been slower or inconsistent depending on the accessory.
Qi2 versions: 2.0, 2.1 and 2.2 are not the same
A key that often goes unnoticed: “Qi2” is not a single thingThere are versions that define different capacities, and this explains why some phones labeled as Qi2 do not reach 25 W.
- Qi 2.0: Enter the magnetic feature. The charging speed remains at 15 W.
- Qi 2.1: adds specific support for magnetic covers/accessories (the phone may not have internal magnets). Also 15 W.
- Qi 2.2: Enables wireless charging 25 W and marks the leap in performance we were hoping for.
Within each branch, small revisions have emerged (e.g., 2.0.1 or 2.1.0). Thus, previous cases have been seen such as HMD Skyline with Qi 2.0.0, and also “Qi2 Ready” phones that, without internal magnets, achieve magnetic alignment using certified cases.
State of the iPhone and Android: Who's Ready and Who's Not
On Apple's side, the transition is straightforward: Recent iPhones already integrate Qi2 and its mature MagSafe ecosystem makes it so that, with certified chargers, everything “just works.” The latest generation reports speeds of Wireless charging up to 25W with MagSafe on the iPhone 16 (with the exception of the iPhone 16e, which does not support MagSafe).
For Android, the picture is more mixed: Many models have not yet completed certification And in some cases, a magnetic case is required to take advantage of the docking and efficiency. This “Qi2 Ready” approach allows manufacturers to support it with fewer internal changes, but it doesn’t always mean jumping to 25W right away.
Samsung, Google and the missing push
The WPC has noted that We will see Qi2-compatible Samsung Galaxy devices in 2025.. In parallel, Google “is helping to achieve this goal” by contributing technology High-power wireless charging to the Qi v2.2 standard. In addition, we work on an extension of Qi2 with moving coils, designed to car mounts: Automatically aligning the vehicle's coil with the phone's coil reduces loss and improves the dashboard experience.
There are already concrete movements: The Galaxy S25 series is presented as “Qi2 Ready”, with magnetic rings integrated into official cases to enable anchoring. This approach copies the basic idea of MagSafe but implements it via accessories, and currently maintains the 15 W in many scenarios.
The Google Pixel 10 case: four models, two speeds
The Pixel 10 family illustrates the version differences very well: Pixel 10, Pixel 10 Pro and Pixel 10 Fold mount Qi 2.0.1, so they stay at 15 W; on the other hand, the Pixel 10 Pro XL adopts Qi 2.2.0 and goes up to 25 W. It is not a capricious decision: Google explains that the reason is thermal management, more favorable in the large model.
This criterion makes sense if we remember the isolated overheating problems in previous generations; limiting power in more compact chassis helps protect the battery and avoid unwanted scenarios. The practical result is that within the same series we see Qi2 at 15 W and Qi2 at 25 W coexisting.
Android Pioneers: OPPO, OnePlus, and the Role of Owners
Even before this wave, OPPO was ahead with the Find X8 and its magnetic integration compatible with Qi2. At the same time, both OPPO and OnePlus continue to rely on proprietary solutions such as 50W AirVOOC: They are very fast if you use the official charger, and they even have fans to keep the heat at bay.
This duality has a clear reading: Qi2 seeks to unify and simplify, but some manufacturers will continue to offer their own options for those who want to maximize speed. In practice, Qi2 will be the "common ground," and proprietary systems will be the "ceiling" for those that accept specific chargers and accessories.
What about compatibility and backward compatibility?
The WPC argues that the Qi2 backward compatibility with Qi remains the same, meaning a Qi2 charger should charge previous Qi devices. However, various reports have indicated that it is not always clear how the new 25W chargers behave with older phones or, conversely, if 2W Qi25 devices scale correctly with older docks.
The reality today is nuanced: load, load; the doubt is the speeds and magnetic profile activation depending on the pairing. That's why it's important to check the specific version (2.0, 2.1, or 2.2) of the phone and charger, and see if the manufacturer explicitly claims support for 25W.
Efficiency, warmth and design: what changes with magnetic alignment
The 25W gain would be useless if it only translated into heat. This is where the magnetic alignment makes a difference: Always placing your phone in the optimal position reduces losses and improves overall performance. Less wasted energy means less heating and, in the medium term, better battery health.
However, thermal management continues to impose pragmatic limits: larger models, with greater surface area and dissipation capacity, are best candidates for the 25W. Hence, some manufacturers ration power by chassis size, as Google has done with the Pixel 10 Pro XL.
Integrated magnets or magnetic cases: two paths to the same goal
The standard allows Qi2 to be implemented with or without internal magnets in the phone. With integrated magnets, the experience is straightforward: you stick your phone on the charger and that's it. No internal magnets, you can turn to official or certified third-party cases to achieve the same alignment effect.
This approach “Qi2 Ready"Samsung is already exploiting this with the Galaxy S25: the brand enables the magnetic experience through cases, even if the device itself doesn't incorporate the ring. It's a way to speed up compatibility without suddenly adopting design changes across the entire range.
An ecosystem that goes beyond mobile
Qi2 25W doesn't just come to phones: desktop chargers, multi-position bases, car mounts and external batteries are already in the process of certification. The WPC speaks of “hundreds of devices” waiting for the laboratory, an indication that we will soon see desks and cars with universal magnetic charging.
The promise is powerful: a single magnetic charger works for both iPhone and Android, with a comfortable grip, no cables, and no juggling to find the sweet spot. This uniformity should also simplify accessory shopping and reduce the compatibility issue.
Certification status: from paper to mobile phones
The start is promising: 14 devices completed certification recently, and there are several hundred in the queue. While the first to reach the market are usually chargers and bases, the WPC and manufacturers already anticipate major mobile phones with support throughout the cycle.
There are also conservative decisions: for example, Google left Qi2 out of the Pixel 9, and some brands prioritize accessories over phones. Still, with the officialization of 25W and public commitments from Samsung and Google, the ripple effect seems inevitable.
Speed vs. cost: what can make adoption more expensive
Adding magnets, redesigning charging circuits, and certifying new profiles involves costs. Manufacturers could pass on some of that extra cost. the final price of the terminals or accessories, something that is especially worrying in mid-range products.
The standard, however, is flexible: Phones with magnets and others that depend on cases coexist.This allows for tiered pricing, allowing users to choose whether they prefer to pay for the full magnetic experience or settle for conventional Qi.
How Qi2 compares to proprietary high-power solutions
As Qi2 matures, the Proprietary systems continue to set recordsOne of the best examples is OPPO/OnePlus' AirVOOC, with 50W wireless when using the official charger and case. The trade-off is obvious: you're dependent on the manufacturer's ecosystem to achieve those figures.
Qi2, on the other hand, bets on the certified universality: You can take your phone to anyone's home, place it on a Qi-certified base, and get a fast and efficient charge without worrying about hidden compatibility issues. It's less extreme in terms of power, but much more convenient for everyday use.
What can we expect in the short and medium term?
With Qi2 at 25 W now official, the next step is to see “Large” Android phones adopting magnets massively and, in parallel, to iPhone and Android converge in universal chargers. The arrival of automotive voice coils It also opens up a very interesting avenue for cars to offer truly reliable wireless charging, without having to play the “adjust a little more to the right” game.
The pace will not be uniform: we will see models with 15 W and others with 25 W Within the same generation, decisions based on size, dissipation, and product positioning will continue. There will also continue to be brands that offer proprietary fast roundabouts for those seeking the absolute maximum.
Frequently asked questions that Qi2 25W answers (or not)
- Will I charge faster than with a cable? In many cases, no; the cable still rules. But 25W wireless finally narrows the gap and makes it possible to use the base beyond the nightstand.
- Do I absolutely need magnets? Not necessarily. You can have a phone without magnets and still achieve alignment with certified magnetic cases; the experience improves, and in version 2.2, 25W is enabled if the hardware allows it.
- What happens to my old Qi chargers? They will continue to work. The question is not "whether it charges," but "at what power" and whether benefits such as the magnetic alignment.
- Will the price of cell phones go up? Integrating magnets and new circuitry is likely to add costs. Manufacturers are already using cases to contain them in some models.
A market finally aligned
After years of promises, the picture is starting to fall into place: Qi2 25W balances convenience, speed and efficiency With a common technological foundation, backed by the WPC and giants like Apple, Samsung, and Google, the jump from 15 to 25 W responds to user demands and to the ecosystem's need to consolidate.
Adoption is already underway: 14 certified devices, "hundreds" waiting, and key moves on Android and iPhone to embrace magnetization. In the meantime, proprietary solutions will continue to exist for those seeking the edge, but with Qi2 25W it becomes much easier. Charge wirelessly without worries, with the realistic expectation that one charger will fit all.
However, the big change is not just the number of watts: it is that for the first time the mobile ecosystem is aligned around a common and efficient magnetic standard, with tangible improvements in the daily experience, a clear adoption path on Android and iPhone, and a horizon of accessories for home, work, and car that promises to put an end to compatibility concerns once and for all.
