Will I be able to charge a qi2 phone on an OG Qi charger?
Yes, the opposite is also true. I know people who charge their Qi1 phones on Qi2 chargers, and you can even stick a metal ring on a phone case so that the Qi2 charger can attach.
That's nice although there is still zero adoption:(
Its not zero. HMD has launched a phone which is QI2 compatible and oneplus 13 also supports this standard
The OnePlus 13 does not, Oppo only have magnetic cases that support their proprietary wireless charging.
That article is from December 4. The only review with some info I could find by notebookcheck written on 19 December claims the oneplus 13 supports both Magsafe and 50w wireless oppo mag.
They don't contradict each other. Every other article has also said it doesn't support Qi2. The only way you can charge it magnetically is theough the case.
Okay so not exactly zero, but until a heavy hitter like Samsung won't even consider, worldwide adoption is going to be low - their flagship just stuck with Qi 1, even though the standard existed for about two or three years at this point.
Samsung doesn't bring hardware upgrades until 2-3years later. They have stagnated and become more like apple.
Its not easy to make changes quickly when you have to then produce hundreds of millions of them.
What's the deal with magnets, are they supposed to replace the coil? Why are these reporters so excited about it?
Because it means compatibility with magsafe accessories. So, you can attach magnetic powerbanks and other things to your phone.
Oh so the magnet if for sticking the power bank to the phone. Okay. I have almost zero exposure to Apple devices so I thought Magsafe is just their name for wireless charging.
Apple helped developed the QI2 wireless charging and magsafe is also a wireless charging standard.
In addition to the other reply, it helps align the tx/rx coils for higher efficiency
This makes sense with a higher power connection
I had a wireless charger melt a few years back cause I had a chunk of metal in my phone case.
Does this new standard include safety checks for stuff like that?
It was always supposed to. Unfortunately, not everyone does a great job of implementing standards.
