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.
