Tech Journalist Backs Qi2 After 1 Year, but 20W MagSafe Beats 15W Thin Android

Summary

  • A year of mostly wireless charging led one tech journalist to conclude Qi2 and MagSafe can handle most daily charging needs, even on thin phones with 3,149mAh and 3,900mAh batteries.
  • 20W wireless charging on the iPhone Air proved the turning point: magnets enabled reliable alignment, a MagSafe battery pack stayed unobtrusive, and the phone reached 50% in 30 minutes.
  • 15W wireless charging on the Galaxy S25 Edge undermined the same setup because it lacked internal magnets, charged noticeably slower, and often needed a case to align properly on pads.
  • Battery wear was less severe than expected after heavy wireless use: the iPhone Air still showed 100% capacity after about 10 months and 231 cycles, while the 13-month-old Galaxy S25 Edge returned a "good" diagnostic result.
  • The broader verdict was conditional rather than universal: wireless charging still does not replace cables entirely, but with fast Qi2 or MagSafe support it is now practical for most charging sessions.
