All Samsung Galaxy S25 owners should get this wireless charging case.
If you intend to use wireless charging with your Galaxy S25 Plus, here we explain why it is necessary to have this official case that not only provides protection but also incorporates magnets.
The new Galaxy S25 series from Samsung features several enhancements, particularly highlighting the Galaxy S25 Ultra model. While the new ultra-wide camera, improved build, and slimmer design are notable characteristics, there is one in particular that could offer significant benefits for everyday use. This model boasts the same 45W charging speeds as its predecessors, although there has been an overall improvement in charging efficiency of approximately 3-4% compared to last year's Galaxy S24 Ultra. Additionally, Samsung has equipped the Galaxy S25 Ultra with support for the Qi2.1 wireless charging standard, making it the first smartphone to support this new generation of wireless charging. However, to take advantage of this functionality, it is necessary to purchase the official magnetic wireless charging case.
Samsung was a pioneer in popularizing wireless charging in smartphones, outpacing Apple and Huawei by several years since the launch of the Galaxy S5 series nearly a decade ago. Since then, although wireless charging standards have not undergone significant changes, speeds have improved to some extent. Apple, on the other hand, took a different approach by introducing the MagSafe wireless charging standard with the iPhone 8 series in 2017, which resulted in a more effective solution to alignment and efficiency issues. This advancement led to the creation of the Qi2 standard by the Wireless Power Consortium (WPC) in 2023, which drew from the lessons learned from the MagSafe system.
The Qi2 standard incorporates many advantages from the MagSafe system to a broader range of devices, such as faster charging speeds and support for magnetic alignment, which eliminates slow charging issues from misalignment. However, different manufacturers approach this implementation in different ways. Samsung has opted for Qi2 support but has not incorporated magnets into the Galaxy S25 series, requiring the purchase of the new magnetic case.
The transparent magnetic case for the Galaxy S25 aims to facilitate Qi2 wireless charging by adding magnets to the back of the device. Standard Qi wireless charging has a limit of 15W, while Qi2 can support up to 25W; however, so far only the iPhone 16 series has been able to take advantage of this maximum speed. The Galaxy S25 series remains at 15W, which, while less than the 50W of charging offered by some competing brands, still represents an improvement.
When using this magnetic case, it can be noted that the Galaxy S25 Ultra takes approximately 3 hours and 20 minutes to charge fully, compared to the faster charging time (67 minutes) achieved with a wired connection. Moreover, connecting the magnetic case shows a considerable difference in charging times, with lower performance compared to other models from competitors.
Despite these limitations, the official magnetic case can be a worthwhile purchase, especially for those who prefer wireless charging, whether they already own MagSafe-compatible accessories or are considering acquiring some. The addition of magnets simplifies the charging process, although it remains slower compared to other technologies. An additional color option for the case would also be welcome, as the current design may not appeal to everyone. Overall, if magnetic wireless charging is not planned to be used, it is recommended to opt for one of the best cases for the Galaxy S25 Ultra available on the market.
