Lithium batteries are used in smartphones, it is quite old technology (about 20 years ago). It is replaced by the nickel. The technology is quite old, so many of you have probably thought about the question of whether we can leave the smartphone to charge overnight. Today we will try to answer this question.
First, let's understand - why people leave Smartphone for charging overnight? In order to receive a device in the morning with 100% charge quantity. Agree, nice to wake up with 100% charge. However, is it safe to leave the smartphone charging overnight?
Batteries used in smartphones today are no different to those used 20 years ago. However, thanks to the device's software that are able to optimize the charging process.
Main danger that the smartphone will be on all night charging is the rise in temperature. Currently, however, smartphones are smart enough. They may stop charging when the battery is charged to 100%. After that, the smartphone will receive energy directly from a connected battery charger - a smartphone in this case will remain cold.
However, this does not mean that there are no problems at all. Battery life is measured in a number of charging cycles. The capacity of battery gradually decreases after the number of charges. In order to improve the performance of the battery life, try not to go beyond 40% and 80% .
Also, don't fast charging, as it may lead to excessive heat, which negatively affects its life.
