Battery : how much charge a smartphone ?.


How often to recharge his phone ? Is it dangerous to leave it plugged in all night ? Should he wait to be at 0 % before you charge its battery ?

While smartphones are ubiquitous in our lives, one of its key components remains poorly known : the battery.

I must admit, on a daily basis, we are concerned that when it threatens to falter, and that one has forgotten his charger. However, the way you recharge your battery can have real consequences on the life of your device.

What is the average life span of a battery ? .

Thelength of life of a battery varies between 3 and 5 years. After that, it loses its storage capacity, resulting in a loss of autonomy for your devices.

In other words, your cell phone turns into a landline phone as it should all the time be plugged in to work !

The memory effect of a battery does not relate to smartphones.

The’memory effect is a phenomenon that prevents some batteries to function properly.

It develops gradually, when they are not regularly charged and discharged at the maximum of their abilities.

For example, if a battery is always charging while only 80 % of its energy has been used, gradually it loses its storage capacity. Somehow, the battery “remembers” that she only needs 80 % between each charge and that is all that it will store. Hence the name memory effect.

Fortunately, this phenomenon only affects the old batteries using the nickel (NiMH and NiCd). Those Lithium batteries used in our smartphones and computers, are therefore not affected by this memory effect.

In daily life, avoid going from 0 to 100 % battery .

The lithium battery of our smartphones don’t like the extremes. To preserve them, it is preferable to be measured. Thus, in daily life, try to maintain a charge level between 40 % and 80 %.

Note that, even if it seems counter-intuitive, several small refills in a day are better than leaving your portable plugged in all night.

Once a month, make a complete cycle.

To recalibrate your battery without exhausting it, the experts recommend to do a full cycle recharge (that is to say, going from 0 % to 100 % of battery) once a month.

You need to charge his phone during the night ?.

As we mentioned above, it is preferable to make several smaller top-ups than to leave your phone plugged in for 8 hours.

However, if you have no other choice, remember to remove the hull of your smartphone before you plug it in. Not only lithium batteries do not like to spend 0% to 100 % of energy, but they also fear the heat and the cold.

If you leave your smartphone plugged in with its hull, then it accumulates heat and this could damage your battery quickly.

The quick reloading.

More and more new Android use the technology Qualcomm Quick Charging to reduce recharge time.

Thanks to a chip PMIC (Power Management IC), these smartphones to communicate with their chargers to monitor the voltage.

We have quickly described above, but the lithium battery of our smartphones don’t respond well to excessive temperatures. A battery that overheated (or freezing) will have a very short life. So don’t let trainer your phone to the beach, in a hot car, for example.

If you can, disable the fast-charging of your Android.

Can you use any charger ?.

It is best to use the charger provided with your phone since the amperage will be perfectly calibrated for your device. If you must use another charger, make sure that it is suited to your model.

Finally, a warning against the chargers counterfeit is always necessary, they abound online and can damage your battery or even catch fire..

Don’t give up devices unloaded .

It is strongly advised not to leave unattended your smartphone (computer, tablet..) in a closet with 0 % of battery, at the risk of never being able to reuse them !

A smartphone battery loses 5% to 10% of its charge per month when not in use. If you have an older model of smartphone that you keep “just in case”, make sure it has at least 50 % battery before putting it aside, and recharge it from time to time, even if you have no use.
