The screen is the biggest battery drain on your phone, consuming up to 70% of the power. Shorten the screen timeout duration to ensure the screen turns off quickly when not in use. Lower the screen brightness or turn on adaptive brightness to optimize power consumption. For phones with OLED or AMOLED screens, using the dark display mode and dark wallpaper settings can save energy, because these screens illuminate individual pixels. Remove unnecessary widgets from your home screen, as they can consume resources and drain the battery.

Consider temporarily disabling external connections if they are not in use or needed. If enabled, they will try to restore broken connections, search for new available connections, download current data, which drains the battery. These connections are: * Bluetooth communication (used for example to connect speakers, headphones) * GPS location (used by applications, for example to determine location, address) * Mobile Data and Wi-Fi network (used to connect to the Internet and download current data - notifications, emails)

Some applications use more power than others. To identify these applications, go to phone settings and search for battery settings sections, where you will find accurate reports of energy use by applications. Review the settings for your most energy-consuming applications. There you will find a number of options that will limit the application's operation in the background, such as disabling notifications and background data refreshing, or energy saving profiles.

Be aware that some applications are more energy consuming than others. Video playback is one of the most battery-intensive activities on a smartphone. To save battery, you can limit the amount of time you spend watching videos, or you can switch to a lower-resolution format. Other energy hungry applications are 3D games and navigation applications.
Phone manufacturers often release software updates that include bug fixes and performance improvements. These updates can also help to improve your phone's battery life. Make sure to check for and install updates regularly.
Restart your phone periodically to close background processes, release memory, clean temporary data and refresh the system. It is advisable to restart your phone once a week.
Disable haptic feedback and unnecessary vibrations for notification, incoming call or sms, as they can contribute to battery drain. Turn off unnecessary system sounds, e.g. when typing on the keyboard.
If you're going to be away from an outlet for a long time, consider using a portable charger to keep your phone charged. Portable chargers are small, lightweight, and can be easily carried in a purse or backpack.
Keep your phone at moderate temperatures, as both extreme heat and cold can affect battery performance and reduce its lifespan. To keep your phone cool, avoid leaving it in direct sunlight or in hot cars. You can also use a case that helps to keep your phone cool.
