In many cases, the charging of our mobile phone batteries is always accompanied by heat. Sometimes it is only slightly hot, and sometimes it is even a little hot. Many users are troubled by this. What's the matter of heating up when the mobile phone is charging? Some people always like to play games while charging the mobile phone, which causes the mobile phone to be in a hot state for a long time. Will this cause any harm to the mobile phone? Is there any way to do it? Solution? Below we have Deji battery manufacturers to explain for everyone one by one
一. Why does the phone heat up when charging?
The charging method of Ni-MH battery adopts "constant current". The Ni-MH battery itself is not afraid of overcharging. When the Ni-MH battery is overcharged, there will be a reverse reaction to prevent excessive voltage rise. This reaction will cause the battery to slightly heat up. In addition, nickel-metal hydride batteries are usually equipped with a thermistor to prevent the battery from overcharging. At present, the working voltage of most mobile phones is around 3.6V, so three nickel-metal hydride battery cells are required. Generally, the nickel-metal hydride battery cell will stop after overcharging to about 1.4-1.5V, and the maximum voltage of the three-cell battery is about 4.4V.
二. What is the hazard of prolonged heating while charging the phone?
1. Long-term heating of the mobile phone battery will cause the internal parts of the mobile phone to heat up, which will cause the mobile phone to restart or hang up the call during a call.
2. Long-term heating of the mobile phone battery will increase the heat of the battery itself. If the battery is sealed (NOKIA and the like are not sealed, the battery is directly installed), the internal air will be greatly expanded, causing the battery to look outside. Protruding, severely will cause the battery to explode.
3. Long-term heating of the mobile phone battery will accelerate the aging process of the mobile phone itself and shorten its life.
三. What is the solution to the heat generated when the phone is charging?
When the phone feels hot while charging, don’t make a fuss. This is energy conversion. We just need to take a small square towel, dip it in alcohol, and apply it on the hot area. After evenly applying it for a few minutes, the heat will quickly dissipate. Help protect the battery. Of course, if there is no alcohol, you can also use water instead, but you should be careful not to dip too much water to prevent water from immersing in some crevices of the phone and damaging the phone components. When charging, you'd better turn off all the software running in the background of your phone. Another very important point is that you must use a phone charger suitable for your phone.
