You need to get your battery replaced imo if not done yet. Its not the software but your battery must have degraded last year or so since it should be 3rd year of usage.
I am also using S10 and I recently replaced my battery as the battery was draining faster. I replaced it wen the battery health was 77%. After battery replacement I am getting roughly 5 hrs SOT. You can check the health of your battery by installing accubattery app.
