Another bad habit to give up: leave the charger plugged into the outlet, even without a phone at the end. Indeed, the cable will continue to consume electricity. To check this, just touch your charger: if it is hot, it is consuming energy. The right thing to do is to always unplug it once your phone has been charged.

Not charging your phone to 100%

If you leave your phone on charge until 100% or wait until it’s completely flat to charge it, that’s also a bad idea. For the battery to discharge less quickly and remain effective longer, the ideal is to maintain its level between 20 and 80%, indicates the Agency for Ecological Transition (Ademe). It is therefore advisable to carry out several point charges during the day rather than a single long one.

Use the charger supplied with the phone

It is better to use the original charger to increase the durability of your battery. Avoid wireless charging, which doubles electricity consumption. Charging a phone from 0-100% with a wired charger requires an average of 14.26 watts per hour, compared to 21.01 watts per hour with a wireless charger, according to research conducted by iFixit and OneZero in 2020.

The “energy saving” mode reduces the amount of energy used by your mobile phone and therefore extends its autonomy by reducing the brightness, disabling automatic application updates, geolocation or automatic rotation of the screen. As soon as the battery drops below 20%, your phone prompts you to activate it. But it is also possible to put it at any time. To activate it on an Android phone, you have to go to the settings, select “battery and performance” and choose “battery saver”. To put it on an iPhone, you have to go to the settings, select “battery”, then “energy saving mode

When you use your smartphone to surf the Internet, Ademe recommends using Wi-Fi rather than 4G, which consumes three times more energy.

Disable unused features and apps

On a day-to-day basis, also consider disabling the features that consume constantly and that you do not use: geolocation, notifications, automatic updates and downloads, updating applications in the background, etc.

Activate “airplane” mode or turn off the phone at night

Finally, putting airplane mode on at night saves battery power. You can also turn off your phone.
