10. Use Dark Themes With Oled Or Amoled Screens.
If your smartphone has OLED or AMOLED screen, using a dark theme will save your battery life a little because these screens switch off the pixel that displays black. On the other hand, LCD screens display black by blocking the backlight using a pixel, which uses battery power.
11. Switch Off Your Phone Assistant
Even apps like Siri and google assistant need battery juice to constantly eavesdrop for your wake commands. As fun as these features are, they are not gentle on your battery life. So, if you don’t need them or use them often, don’t leave them running.
