Galaxy S25+ Battery Test Shows 95% Health at Both 80% and 100% Charging

Summary
One year after purchase, two Galaxy S25+ phones showed the same 95% battery health in AccuBattery despite one being capped at 80% charge and the other regularly charging to 100%.
Capacity estimates still differed: the 100%-charged phone measured 4,505mAh versus 4,406mAh before recalibration, and Battery Guru later put the author at 94% health and 4,460/4,755mAh versus the mother's 98% and 4,671/4,755mAh.
Usage patterns may explain part of the gap, with the author describing heavier use, more AI features and stricter battery-saving settings, while the mother charged overnight and used default brightness and timeout options.
The comparison undercuts the expectation that an 80% cap would show a clear short-term benefit after a year, though the author argues any payoff may emerge only over several years as lower-voltage charging reduces wear.
The test also points to charger quality as a separate battery-health factor, warning that cheap cables and mismatched wattage can heat a phone regardless of charging limits.
