Samsung Users Can Extend Battery Life by Disabling 60W Fast Charging
3 articles · Updated · How-To Geek · Aug 16
Summary
Samsung phones can run cooler and preserve battery health longer if users switch off fast charging, a setting available in Battery or Charging settings depending on the One UI version.
60W charging speeds up top models such as the Galaxy S26 Ultra, but the high voltage conversion and heavier current create extra heat inside the phone — the main driver of long-term lithium-ion battery wear.
Samsung blocks the toggle while a phone is plugged in, so users must unplug first; removing a case or closing apps may reduce surface heat but does not stop the battery from generating it.
300 to 500 charge cycles typically bring batteries to replacement territory, making the trade-off a choice between slower 15W or 5W charging now and avoiding a $50-$100 battery swap or a $400-$1,200 new phone sooner.
