Small habits add hours to your day and years to your battery. Lower your screen brightness or use auto-brightness, and turn on dark mode on OLED phones. Close or restrict background apps, and switch on battery saver when you're running low.
For long-term battery health, avoid charging to 100% overnight every day and keep your phone out of extreme heat — heat is the biggest killer of battery capacity. Use a quality charger and cable rather than random cheap ones, which can charge inefficiently. Finally, top up in short bursts through the day instead of always draining to 0%. These simple changes keep your battery lasting longer, both daily and over the years.
