Why you should avoid leaving it plugged in all night
It’s convenient, yes. But your phone doesn’t « sleep » during this time. Once it’s fully charged, it receives micro-injections of energy to keep it at 100%. This process, called « trickle charging , » keeps the battery at a constant voltage… and generates continuous heat. The result? A battery that’s working uselessly for hours.
The ideal zone: between 20% and 80%
The “sweet spot” for your smartphone
Experts agree: lithium-ion batteries perform best and last best when they operate between 20% and 80% of their charge. In other words, there’s no need to charge to 100% . It’s a bit like keeping a car between 30 and 110 km/h: that’s when it’s most efficient and consumes the least.
Good habits to adopt every day
-
Don’t always charge « all the way »
Unplug your phone around 80%, especially if you don’t need to use it intensively right away.
-
Avoid prolonged charges
At night, use a programmable outlet or activate an “optimized charge” option if your device allows it.
-
Use a suitable charger
Original (or certified) chargers are designed to be battery-friendly. Counterfeit models, on the other hand, can quickly damage them.
-
Avoid gaming or streaming while charging
These activities produce heat and force your battery to do double duty: charging while powering heavy tasks.
A change of habits that is worth it
By rethinking your charging habits, you can extend the health of your battery by months, even years . And that’s good for your wallet… and the planet. No need to obsess over the plug : a few adjustments can make a difference.
Remember: the best charge is one that respects the natural rhythm of your battery.
