Qi, Qi2 or MagSafe? The Wireless Charging Labels Finally Explained
Quick answer: Qi is the old basic standard: no magnets, slower, easy to misalign. Qi2 adds magnets based on Apple’s MagSafe design, so the phone always snaps into the right spot and charges faster. MagSafe is Apple’s own version. For iPhone 12 and newer, choose Qi2 or MagSafe.
Qi (the original)
Works with almost every wireless-charging phone, but has no alignment magnets. If the phone sits slightly off-centre, charging slows down or stops and the phone gets warmer. Fine for a bedside pad if you place it carefully.
Qi2 (the new standard)
Qi2 uses a magnetic ring based on MagSafe, so the coils line up every time. That means more efficient, cooler charging, and it works on Android phones that support Qi2 too. Newer versions support higher wireless wattage on compatible iPhones.
MagSafe (Apple)
Apple’s magnetic system for iPhone 12 and newer. Official MagSafe chargers and certified ones can deliver faster wireless charging on recent iPhones when paired with a strong enough USB-C adapter.
What actually decides your speed
- Your iPhone model.
- The charger standard and its rated wattage.
- The power adapter behind it — a weak 5W cube limits even the best charger.
- Your case: it needs to be MagSafe-compatible or thin enough.
- Heat — iPhones slow down charging when warm.
Our advice
Pick a Qi2 or MagSafe charger with a matching USB-C PD adapter, and use a MagSafe-compatible case so the magnets hold firmly.
FAQ
Will a Qi2 charger work with an older iPhone?
iPhone 8 to 11 can charge on Qi2 pads as basic Qi, without the magnetic snap and at lower speed.
Is wireless charging bad for the battery?
No, but it creates a little more heat than a cable. Good alignment (Qi2/MagSafe) keeps that down.
