Apple’s iOS 18.2 update may look routine — but it’s hiding a major surprise.
After installing the latest version, many iPhone users say their devices now charge noticeably faster without heating up as much.
Posts across Reddit and X describe charging improvements of up to 20% faster times, especially with MagSafe and USB-C cables. One user wrote, “I thought my charger was upgraded, but it’s actually the software!”
Apple hasn’t mentioned any charging-related changes in its notes, but developers digging into system files discovered a new Power Efficiency Framework — a small background service that appears to optimize charging current based on temperature and app activity.
This could be Apple’s quiet effort to extend battery health while still boosting speed.
No flashy announcement, no marketing — just a silent upgrade that users are now uncovering.
So if your iPhone suddenly charges faster after iOS 18.2, you’re not imagining it — Apple just made your charger smarter.
