Top 15 tips to extend battery life on Android or iPhone

The battery saver isn’t just the only solution. Some tips can help you extend your battery life and life, no matter what device you’re using. Here are some simple and practical tips for lowering your system’s energy consumption.

Advice to remember

Adjust your screen’s brightness according to your minimum visibility requirement; for example, in the evening, very low light is enough to see your device’s screen. However, the lower the brightness of your screen, the less energy it uses. Remember that your screen is the primary source of battery discharge.

  1. Uninstall all apps you no longer use. In this way, they do not work in the background and do not consume energy.
  2. Adjust your screen’s brightness according to your minimum visibility requirement; for example, in the evening, very low light is enough to see your device’s screen. However, the lower the brightness of your screen, the less energy it uses. Remember that your screen is the primary source of battery discharge.
  3. Choose a dark theme for your black preference system (black wallpaper also). This allows you to have parts of your screen turned off at any time, which will significantly decrease your battery’s energy consumption.
  4. Avoid playing mobile games if you want to keep your battery charged. You should know that mobile games are very resource-intensive. Make sure you’re close to a charger if you want to play.
  5. Connect to the wifi network whenever possible. Generally, the cellular connection depletes the battery faster than wifi.
  6. Turn off the network connection you don’t use like Bluetooth, wifi, GPS (the greediest), and radio. These are connections that discharge the battery even when they are not in use.
  7. Use battery-saving mode on your device. It is a very efficient model designed by the manufacturer. This mode activates battery-saving functions that applications cannot replicate.
  8. Avoid using the vibrator on your device as it requires a small motor to trigger vibrations. This small component will deplete your battery faster.
  9. Don’t use boosters that make your device faster. These are applications that increase the frequency of your processor by giving it more energy. These applications also find that they block energy-saving processes.
  10. You must then choose between a robust device that discharges quickly and a slower device with better battery life.
  11. Don’t leave your communications apps running when you’re not using them like Facebook, Twitter and others because they’re apps that keep updating data every second to show you everything that’s happening on the network.
  12. The widgets on your home screen are also apps that need the energy to work. Just because they seem inactive doesn’t mean they are inactive. You need to delete all widgets that you don’t use because they consume a lot of energy to show you the new information every second. Not to mention that the animated wallpaper also works in the same way as an app. The animation effects will also have an impact on your battery consumption.
  13. Don’t forget to update your apps. Because apps are often updated to use less energy, you need to make sure the apps you use are up to date.
  14. If you are in an area with low cellular network coverage, your device will consume a lot more energy to try to pick up the signal. This will hurt your battery life. Just switch to airplane mode if you are in an area where the signal is weak.
  15. Turn off notifications that appear all the time; not only is it annoying, but they also consume energy. Blocking an app notification will prevent the processor from checking it from time to time; it will help you extend your battery life.
