What causes the phone battery to heat up when charging?
The phone to heat up, when charging. This is become a common situation. Let Eparts phone battery manunfacturer tells you some knowledges which is about phone battery to heat up, when charging.
Why the phone battery geat up, when charging?
The charging method of Ni-MH battery adopts "constant current". NiMH batteries themselves are not afraid of overcharging. The reverse reaction occurs when the NiMH battery is overcharged, preventing the voltage from rising too much. This reaction causes the battery to heat up slightly. Additionally, NiMH batteries are often equipped with a thermistor to prevent overcharging of the battery. At present, the working voltage of most mobile phones is around 3.6V, so three NiMH batteries are required. Generally, the nickel-metal hydride battery will stop when it is overcharged to about 1.4-1.5V, and the maximum voltage of the three-cell battery is about 4.4V.
What are the dangers of the phone getting hot for a long time while charging?
1. The long-term heating of the mobile phone battery will cause the internal components of the mobile phone to heat up, causing the mobile phone to restart or hang up during the call.
2. Long-term heating of the mobile phone battery will increase the heat of the battery itself. If the battery is hermetically sealed (NOKIA or the like is not sealed, the battery is directly installed), the air inside will expand greatly, causing the battery to look out. Protruding, it will cause the battery to explode.
3. The long-term heating of the mobile phone battery will accelerate the aging process of the mobile phone itself and shorten its life.
How to deal with phone battery heat up?
When the phone feels hot while charging, we just need to take a paper towel, dip it in alcohol, put it on the hot place, and the heat will dissipate quickly. Help protect the battery. Of course, if there is no alcohol, you can also use water instead, but be careful not to soak too much water, so as not to soak into some gaps in the phone and damage the phone components. It is best to close all software running in the background of the phone while charging. Another very important point is that you must use a phone charger that fits your phone.
