Samsung ’s new Galaxy S25 serial brings a few improvements , specially for the flagshipGalaxy S25 Ultra . While the young ultrawide camera , improved physique , and thin body may be the one that bear out the most , one particular feature could provide the best quality of life improvements .
The Galaxy S25 Ultra come equipped with the same 45W charging speeds as its harbinger , although overall charge speeds have been improve by around 3 - 4 % over last year’sGalaxy S24 Ultra . Alongside this , however , Samsung has also equipped the Galaxy S25 Ultra with compatibility for the Qi2.1 wireless charging standard , making it the first smartphone to stomach the next generation of wireless charging .
However , you require to grease one’s palms the official Magnetic Wireless Charging Case to take advantage of this . I ’ve been using it for a few days and here ’s why everyone should buy it if you plan to wirelessly charge your newGalaxy S25 .
Understanding the history of wireless charging
Samsung was the first to make wireless charging platitude on smartphones — beating Apple by two years and Huawei by four years — with the launching of the Galaxy S5 series almost a decade ago . However , since then , the radio shoot down standard has n’t changed much , although upper have passably amend .
Meanwhile , Apple have a different approach . The iPhone 8 series in 2017 was the first to put up Qi wireless charging , but just three geezerhood later , the caller rolled out the MagSafe magnetised radio charging touchstone for all of its flagship phones . The answer was a much ripe radio rouse standard and one that solve many of the conjunction and efficiency problems with the core Qi monetary standard .
Recognizing this , the Wireless Power Consortium ( WPC ) adopt from MagSafe to progress the Qi2 wireless charging standard in 2023 . The WPC is an manufacture radical that builds the subject radio set charge standard , and Apple formally join it alongside the rollout of Qi in its iPhones . This would finally establish beneficial for all smartphones with the coming of Qi2 point two age ago .
What is Qi2 Magnetic Charging?
The Qi2 standard add many of the welfare of MagSafe charging to the wider smartphone ecosystem . Mainly , it benefits from the fast wireless charging upper and crucially , summate financial backing for magnetic conjunction . The latter has made the MagSafe system so efficacious , and solved one of the biggest problems with wireless charging in ecumenical : ensuring the courser is perfectly aligned with the coils in your phone . Often , a slender misalignment would make charging much slower — or it would n’t form at all — but Qi2 consign solves this with strong magnets .
However , like the sleep of the Android ecosystem , different manufacturers take unlike approaches to implementing this . Oppo and OnePlus both support magnetic wireless charging , but utilise a proprietary standard to achieve double the prescribed upper of Qi2 . Meanwhile , Samsung opted for Qi2 musical accompaniment but choose against let in magnets in the Galaxy S25 series ; instead , you necessitate this Modern Magnetic Clear Cover .
The case to buy for superfast wireless charging
The Galaxy S25 Magnetic Clear Cover does exactly what you carry it to : it ’s a clear cover that adds magnets to the back of your phone and is designed to allow you to take full advantage of the Qi2 wireless charge velocity . While first - contemporaries Qi charging caps out at 15W , the Qi2 standard technically supports up to 25W , but so far , theiPhone 16 seriesis the only earpiece to abide this full speed , and that ’s when used with an updated MagSafe battery charger . The Galaxy S25 Series is restrain to 15W charge , although this still pales to the50W wireless charging offered by Oppo and OnePlus .
Like many of the best iPhone clean subject , the magnet sticks out like a sore thumb — not literally , but figuratively given the design — but hopefully , the prescribed case will spur many third - party companies to set in motion a range of dissimilar invention . I ’ve also recently been using the new vegan - leatherGalaxy S25 Ultra Kindsuit shell , and I do wish that Samsung had also included magnet in this case , or its official silicon case , as this would have offered the best of all worlds .
Nonetheless , the magnetic clear cover offers welcome auspices for your new Galaxy S25 , allow you to show off the colours — such as the gorgeous Navy and Coral Red Galaxy S25 — and features preciseness cutouts for the dissimilar interface . However , one thing to note is that , unlike the Kindsuit case that bring home the bacon full coverage for the charging ports , the Magnetic Clear Cover leave that area mostly unprotected .
How long does it take to charge the Galaxy S25 Ultra wirelessly?
The lack of an prescribed vitrine with magnet that is n’t clear means you have a choice : do you require a clear case with magnets or a more protective slip that foregoes magnetic wireless charging ? The only way to determine whether it ’s worth it is with a charge exam , so after waiting for the Galaxy S25 Ultra battery to run out — which is no meanspirited exploit as it has systematically lasted for multiple days — here ’s what I recover .
I ’ve previously tested the Galaxy S25 Ultra ’s wired consign speeds and found that it take around 67 minutes to saddle to full . Given the 5,000 mAh battery , this produces a interchangeable bear down pep pill of 75 mAh / arcminute , which is the fastest I ’ve ever know on a Samsung speech sound , but still pales when compared to a key rival twist that is more than doubly as fast .
Meanwhile , with the Magnetic Charger Cover attached and the sound magnetically attach to the Belkin adjustable shoot stand — which can charge at the full 15W speeds — the Galaxy S25 Ultra takes 3 hours and 20 arcminute , which is tantamount to 25 mAh / minutes . For setting , the OnePlus 13 charges to full in 75 minutes — or 81 mAh / minute — which is over three times faster than the Galaxy S25 Ultra .
What about a quick charge ? While the Galaxy S25 Ultra tutelage to 50 % in under 30 minutes when plug into a 45W charger that supports Samsung Fast Charging 2.0 , it takes over an hour longer at 1 minute and 35 minutes when burden wirelessly with the Magnetic Charging Cover .
Interestingly , when you first connect the Galaxy S25 Ultra it enunciate it will take just 2 hours to charge to full , but this constantly slip to almost three - and - a - one-half hours .
Why this case is still worth buying
Qi2 charging is an absolute mess , and although the Galaxy S25 Ultra supports the standard , it is still limited to just 15W charging . This is a far vociferation from the 25W charging supported by the iPhone 16 professional , and significantly sluggish than the 50W proprietary charging banner offered by Oppo and OnePlus .
However , despite this , the official magnetised charging cover song is still deserving bribe if you prefer to burden your telephone wirelessly , you have MagSafe - compatible supplement already in your home , or you ’ve been eyeing up charismatic accessories for your dwelling house , office , or car .
The addition of magnets lay down charging an rank breeze , and while it ’s slow and I still plan to plug in when I demand a quick charge , this has speedily become my favorite way to shoot down my phone overnight . I just care that Samsung offered a different color option other than exonerated ; I dislike the look of a magnet on a phone — this is n’t just limited to Samsung ’s case — and think there could be so many pretty way to go through this . Of course , if you do n’t design to use charismatic wireless charging , you ’re better off pick up one of thebest Galaxy S25 Ultra casesinstead .
