Using Your Phone While Charging Won’t Hurt Battery Life (Just Slower Recharging)
Using a phone while it’s charging won’t damage the battery thanks to features like bypass charging that shifts power to running apps and helps control heat; expect slower charging during intensive use, and note that iPhones don’t currently support bypass charging. Overall, modern phones manage heat well, but overheating is the main risk, so limit heavy use while plugged in. Overnight charging is safe due to protective charging and trickle charging, and for longevity you’re better off charging when the battery is around 20–80% rather than letting it fully drain.
