iPhone charging to 100% even when optimized to charge up to 80%
My iPhone 15 has been set in Optimized charging to max 80 pct, (charging optimization) but last night it charged to 100 pct while in Sleep mode. I checked the settings to make sure that I had not changed it by mistake, but it still showed the 80 pct. The graph for the last 24 hrs also shows that the charge never exceeded 80 pct until last night, while in Sleep mode. Any ideas as to why this happened? Is there any additional change I need to make?
