The procedure varies between smartphones, but the general mechanism remains the same. You should look for settings related to running apps in the background.

In a Xiaomi Note 7 for example, the procedure is as follows: go to the “Settings” of your phone, then to “Battery and performance”.

If you open a lot of apps, remember to close them when you’re done using them. Because apps usually stay active by default and thus quickly consume the power of your smartphone.

Another good move: refine your notifications. It’s not uncommon to be inundated with notifications from more or less used apps. Sort to receive only the notifications that are really relevant to you. Check the “Settings” of your smartphone and click on “Notifications”. The list of all the apps that send you notifications is displayed: you can then manually uncheck those from which you no longer want to receive notifications.

Uncheck the option “Turn on lock screen for notifications” or turn on “Don’t turn on screen for notifications”, depending on the smartphone models Incoming notifications will no longer automatically turn on the screen, they will only appear when you unlock your smartphone yourself.

Limit unnecessary connections

Your smartphone’s sharing and tethering options are typically the most power-hungry. The right reflex to have: Put your smartphone in “Airplane” mode when not in use. You will not be able to receive calls or text messages. To do this, swipe up from the top of the screen to quickly reveal your smartphone options and select “Airplane mode.”

If you want to remain reachable, act according to other parameters: disconnect from Wi-Fi, but also from Bluetooth or even from geolocation. All of these options can be accessed from the same menu as “Airplane Mode”.

Activate power saving mode

This feature is also called battery saver, depending on smartphone models and brands. Helps extend loading time by stopping app data updates except when you open them on your own. To activate it, go to “Settings” of your smartphone and then to “Battery and performance”.

Depending on the models and brands, it is sometimes possible to define in a personalized way the load threshold from which the energy saving mode is automatically activated. For example, you can decide that when your battery drops below the 20% threshold, economy mode kicks in automatically.

Learn how to properly charge your smartphone

To conserve your smartphone battery, you must also have good charging hygiene! The ideal: privilege power outlets, instead of recharging by USB port. In general, it is advisable to use the charger from the manufacturer of your smartphone to avoid failures that could attack the battery. Finally, it is not recommended to leave the laptop charging for too long, such as plugging it in overnight, to avoid any battery overheating issues.
