In today's time, smartphone is the need of every other user. Whether a housewife or a working professional, every user needs this device for their different tasks. At the same time, along with using the smartphone, proper maintenance of the device is also required.
Many users are making some minor mistakes regarding the charging of the smartphone, due to lack of information, incidents like fire in the phone often happen.
If the smartphone is charged properly then it can be run for 2 to 3 years without any problem. The 20-80 charging rule comes in handy for charging the smartphone.
What is the 20-80 rule for charging a smartphone?
In fact, according to experts, in most of the cases of fire in the phone, the fault in the battery of the phone becomes the reason. If the phone is not charged properly, then the battery of the device starts getting damaged.
Talking about the 20-80 rule for charging the smartphone, the user is advised that he should never charge the device to full charge i.e. 100 percent. When the battery of the device is low, most of the users put the smartphone on charging, but to use the phone for a long time, they keep it on charging for a long time.
Fully charging the phone's battery has the opposite effect. You must have also noticed that if the phone is kept on charging for a long time, it gets hot. In such a situation, the user is advised to charge the phone not fully but only up to 80 percent.
On the other hand, when the battery is low, it is considered correct to charge the smartphone with 20 percent low battery. However, most of the users charge the phone only when the battery is dead. This is the reason that the problems related to the battery start coming in the user's phone in no time.
