As Apple's MagSafe certified chargers are gradually retiring from history, last year, the new QI2 open standard came into being.
At this week's Consumer Electronics Show (CES), we saw a wide range of accessory options that support the new QI2 standard.
In August last year, we have already seen the traces of the new QI2 charger, and this year's CES has attracted all kinds of manufacturers from large companies such as Belkin to Chinese OEMs, who have launched chargers and battery packs that support the new standard.
While many of the accessories at the show may take weeks to ship, we can now buy some of the most popular brands online, ranging from 3-in-1 stands to battery packs.
It is foreseeable that by the end of 2024, with the popularity of QI2, "Magsafe" could become a thing of the past. In fact, the new QI2 charging dock not only supports the full-speed charging of the latest iPhone models, but also comes with a number of interesting new features.
For example, Belkin's BoostCharge Pro 3-in-1 magnetic stand has a feature that the MagSafe version doesn't have: the user can rotate the charging pad so that it tilts up or down.
In the past few years, the development of the QI2 wireless charging standard has become a hot topic in the industry.
QI2 is an evolution of the Qi wireless charging standard developed by the Wireless Power Consortium (WPC) many years ago. This standard is designed to provide a faster and more efficient wireless charging experience.
The Qi standard includes two charging profiles: the Baseline Power Profile (BPP) and the Extended Power Profile (EPP). BPP provides only 5 watts of charging power, while EPP is capable of handling charging rates of up to 15 watts.
However, Apple has been limiting Qi EPP charging to 75 watts, this limit until iOS 112 was released after it was released, and this version brings wireless charging to the iPhone.
Over the years, this limitation has made the iPhone one of the slowest smartphones to charge wirelessly.
In contrast, most of Samsung's phones are capable of easily reaching 15W EPP charging, while other phone brands such as OnePlus and Google have employed proprietary technology to increase charging speeds.
However, Apple seems concerned that increasing the charging speed could cause potential damage to the iPhone and create unnecessary power consumption for the environment.
To combat this, Apple introduced MagSafe, which is a magnet ring that ensures that the coils are always aligned while charging.
While MagSafe doesn't completely solve the inefficiencies of wireless charging, it does avoid wasting more power and reducing unnecessary heat generation.
Apple partnered with WPC to develop an "open" version of MagSafe, which came to be known as the QI2 Magnetic Power Profile (MPP).
The introduction of this standard provides an opportunity for other manufacturers to develop certified chargers that are not limited to Apple's MFI program members.
Now, with the rollout and adoption of the new QI2 standard, we expect to see more certified chargers and battery packs emerging into the market. Not only do these products support the full-speed charging of the latest iPhone models, but they also come with a number of interesting new features.
For example, some of the most ** QI2 chargers can rotate the charging pad so that it tilts up or down, a feature we have never seen before at the MagSafe booth.
Overall, with the popularization and development of the QI2 standard, the wireless charging market will become richer and more diverse. Users will have more choices and a better charging experience, and manufacturers will also have the opportunity to launch more innovative products.
Unfortunately, the QI2 does not support all iPhone models. Although Apple introduced MagSafe in the iPhone 12 series, this model does not seem to support QI2.
The MagSafe change in iPhone 13 may be related to this issue. There was a lot of speculation at the time that these upgrades might bring features like faster charging or reverse wireless charging to the iPhone 13, but it didn't come to fruition.
Still, Apple may have laid the groundwork for the new QI2 MPP standard. In any case, QI2 charging only supports fast charging on iPhone 13 and later.
So, if you're still using the iPhone 12, you'll have to choose Apple's MagSafe accessory.
It's also worth noting that while the entire iPhone 15 series of products supported QI2 at the beginning, it wasn't until iOS 17 in DecemberIt was only after the release that Apple added support for the Qi2 feature to the iPhone 13 and iPhone 13.
As a reminder, like MagSafe, the QI2 charger is fully backwards compatible with the Qi BPP and EPP standards. So, even if you are using an iPhone 12, you can still get power from the QI2 charger, which, like other magnetic QI chargers, can only reach 75 watts.
