Battery and charging
What is Qi2 wireless charging and how is it different from Qi?
Qi is the Wireless Power Consortium's wireless charging standard: you set the phone on a pad and it charges by induction, no cable needed. Qi2 adds a ring of magnets (based on Apple's MagSafe) that aligns the phone automatically, reducing losses and heat, and supports up to 15 W; later versions go up to 25 W.
What Qi2 improves
With classic wireless charging, if the phone sits off center on the pad, it charges slowly or not at all. Qi2's magnets keep it centered every time, so energy transfer is more efficient.
Qi2 also enables magnetic accessories that work across brands: car mounts, stands, and battery packs that snap onto the phone.
Compatibility
A Qi2 charger still charges Qi phones without magnets, but without magnetic alignment or Qi2's maximum power.
To charge at top speed, the phone and charger must support the same version. Phones without built-in magnets can use a compatible magnetic case to line up.
What to check before you buy
- If your phone supports Qi2, look for chargers with the certified Qi2 logo.
- Check the wall adapter's wattage: a wireless charger needs a good USB-C adapter to perform.
- Wireless charging produces some heat; that is normal, but avoid using it in the sun or with thick cases.
