![]() Generally, when converting the alternating current to direct current, a normal battery charger is capable of transmitting around 70% of electric current, while the other 30% is converted to heat energy and is diffused. However, the conversion process certainly causes some energy losses since the conversion efficiency cannot up to 100 percent. This kind of process refers to the conversion of low voltage to high and the conversion of alternating current (AC) to direct current (DC).ĭue to the fact that most mobile phones and other electronic devices only support low-voltage direct current which can ensure consumer safety while the normal current from the socket for home use is high-voltage alternating current, there is a need for voltage and current conversion. Well, the vast majority of causes rest in a process occurring inside of a charger which is specific to charging - voltage and current conversion. But why does the charger get hot during the charging process? That being said, a battery charger charges a mobile phone by transmitting electric current for a period of time. More specifically, reversed to the battery's working which converts chemical energy stored in it to electrical power to give the power to devices, a battery charger carries electric current through the battery by converting the electric power to the chemical energy which is used to regenerate the run-out electrolyte inside of a battery. Essentially, a battery charger works by transmitting electric current to batteries for a period of time in the hope that the cells (power-generating compartments) inside of the batteries can maintain the energy passing through them. Just like a battery that gives you power to operate your phone or any other mobile device, a battery charger gives the battery power to make it work regularly. How Do You Cool Down an Overheated Phone? USB Cable or Adapter: Why is Your Fast Charger not Fast Charging GaN VS Normal Battery Charger: See How They Differ What Is GaN Charger? Exploring the New Charging Tech Tips on How to Select A Good Data Cable for Your Mobile Phone Can You Use a New 30W USB C Power Adapter for All Apple Devices and Why? Why Does Your Battery Charger Heat up When Charging Your Phoneīefore discussing why a battery charger heats up when charging a mobile phone, having a understanding of how a charger works is helpful. Then the article will keep exploring the main questions and will also give you some tips on how to reduce the damage to your phone battery. In order to better explore the questions, we'll first discuss the reason why your battery charger and even your phone warm up during the charge. Is it normal for a battery charger to get hot during the charge? Can it cause any damage to the phone battery? Well, take it easy. ![]() When facing this situation, many people will be afraid if it can cause burning or damage to their devices. In fact, when charging the battery of mobile phones, tablets, and even laptops, battery chargers especially those for Li-Ion batteries will inevitably heat up and even make the charged devices get hot. It isn't surprising if you also encounter this problem. Why does this happen? Is this normal? Can this cause damage to the phone battery?" This is often accompanied by the heating up of my phone. "Ouch! Every time I use my battery charger to charge my phone, it gets hot to the touch when it's plugged in for a while. Is A Hot Battery Charger Normal and Can It Damage Phone Battery
