There is no doubt that most of us charge our cell phones at night. Because of the study or work conditions, or any other reason, we may not be able to provide the time needed to charge our phones during the day due to the time it takes to complete the charging process, so we wait until night until we can charge our phones.
But is this the right way to charge the phone?
This is what we will cover in this article
While the complete charging process takes a few hours at most, depending on the type of charger or the quality of the phone, the phone remains connected in most cases for eight hours or more! Cell phones are equipped with a lithium-ion battery, which has the advantage of quickly recharging, but it deteriorates when exposed to a very high voltage. Additionally, overcharging can heat up the battery and in some cases lead to its ignition, as we saw with the Galaxy Note 7 that caught fire.
However, to prevent this from happening during the charging process, most manufacturers have equipped phones with systems that turn off power automatically when fully charged.
But the problem is that even when not in use, the phone suffers from low discharge. Once the battery drops below a certain level, the charging will be restarted again until it reaches 100%, and thus the phone is exposed several times during the night to a lot of “mini-charges” which consumes the battery prematurely, which helps to heat the phone.
Is the charger alone consuming electricity as well?
Plus, the phone isn’t the only one that consumes power. When the battery is charged to 100% and the charger is left connected because we are charging the phone while we sleep, we do not notice the completion of the charging process, the charger will continue to absorb electricity. The charger consumes an average of 3.68 watts of power when charging and 2.24 watts of power when remaining connected to the mains while charging the battery, which is a waste of unnecessary energy.
Thus, to increase the life of the battery, it is always recommended to keep a charge between 30% and 80%, meaning not to wait until it is completely discharged and also to avoid charging it to the maximum extent.
