I’m now getting around 7 hours of screen-on time going from 100% down to 15%.</P><P>Before this, when I first updated to One UI 8.0, my battery life tanked and I was barely getting 4 hours of SOT on the same usage pattern. Whatever Samsung did with this patch seems to have fixed the drain. Anyone else seeing better battery life after the October update?</P> Mon, 03 Nov 2025 02:42:44 GMT s1atoshi 2025-11-03T02:42:44Z
