Is it okay to leave your phone charging overnight?

Yes, it's generally safe to charge your phone overnight because modern phones have built-in protections to stop overcharging, but it's best to use good practices like placing it on a hard, cool surface (not under a pillow) and enabling "Optimized Charging" to minimize heat and preserve long-term battery health. While the phone won't get damaged by "overcharging," keeping it at 100% constantly can slightly stress the battery over many months, so smart features help manage this.

Is charging to 100% bad on an iPhone?

Charging your iPhone to 100% isn't inherently "bad" and is safe due to built-in protections that stop charging at full, but consistently charging to 100% and leaving it plugged in, especially overnight, can slightly increase battery aging over time compared to keeping it between 20-80%. For optimal longevity, use features like Optimized Battery Charging to manage charging, which reduces stress by pausing at 80% and finishing closer to when you need it, rather than letting it sit at 100% for hours.
