properly charge your phone's battery

Smartphones are great, but the problem is invariably the battery. So to save a few percentages of battery, everyone has his little trick.

Decrease brightness, turn off WiFi or geolocation, for example. But some tips may be counterproductive. For example, letting the battery run out completely and reloading it at once is no longer relevant, it was especially effective on older nickel batteries. This can even decrease the autonomy of the device.

Since then, our phones and laptops use lithium batteries, which have a very different functioning.

Do not leave your phone charged at night

Theoretically, a lithium battery can be damaged if it continues to charge when it is full. But most laptops and smartphones automatically detect this and cut the load. However, you should avoid leaving your smartphone plugged all night.

Indeed, leaving the battery charged to the maximum is not very good to it . And it's even worse if the battery is hot .

But do not leave your battery too discharged

Where it gets complicated, it is not necessary that the battery is too discharged. For simplicity, if it is too discharged or too busy, it is "stressed" and damaged more quickly than if it is still moderately loaded. Normally, manufacturers set a limit (at 5%) where the smartphone turns off so as not to damage the battery too much.

In fact, to really take care of your battery and avoid too much stress, do as professionals. Batteries in electric cars charge up to 80% and discharge up to 30%.

Indeed, you should not hesitate to charge your smartphone as soon as you can rather than wait until it is in the red and recharge it at once. By doing this, we stress the battery, which can only reach 300 to 500 cycles of discharges before seeing its autonomy decrease.

on the other hand, it is recharged twice as often (50% battery left, for example 80% to 30% as seen above, and recharged 50%), the battery holds up three times longer .

Lithium batteries do not like extreme temperatures. It is recommended to charge your notebook between 0 ° C and 40 ° C.

If using your smartphone when charging it is not contraindicated, be careful not to use a greedy application that will heat the phone. Also, do not hesitate to unplug your charger if the phone gets too hot or if you are in direct sunlight. And in general, avoid the heat of your battery.

There is only one case where it is necessary to do a discharge and a full charge of the battery: if the indicator of it starts to say anything. It must have happened to you: you have 30% of the battery left, but in 15 minutes the phone turns off.

This may mean that the gauge is misaligned. To repair it, it suffices to carry out a complete cycle of discharge and charge. If that does not solve the problem, check also in your applications if one of them does not consume more autonomy than reason .

If you plan to stop using your computer or smartphone for several months, think about your battery before storing it in a closet. First of all, make sure that the battery will be stored cool. Indeed, the hotter it is, the more the battery will lose its autonomy.

Also, even if your device is turned off, the battery will empty slowly. Very gently, but all the same, it is better not to leave a discharged battery to abandon. The best option is to charge your battery at 40%. Thus, if you store it in a room at 25 ° C for a year, its maximum autonomy will be almost intact, while a battery fully charged and stored a year will lose 20% of its autonomy.
