A few small tweaks go a long way: keep brightness around 50–60%, turn on battery saver, and close apps running in the background (I usually find Chrome tabs are the biggest drain). Disable startup apps you don’t need, switch off Bluetooth/Wi-Fi when not in use, and avoid heavy tasks on battery. Also, don’t keep it plugged in all the time, letting it cycle between ~20–80% has helped me maintain better battery health over time.
