why is my phone hot when charging

It is not recommended to charge a mobile phone with a low electricity voltage as it tends to damage both the phone and the charger.

I have experienced this before, using a low voltage to charge my old samsung phone.

Both the phone and the charger was well heated up to the extent I though the charger will explode, but it didn’t.

I had to quickly unplug the charger and the phone.

At the end of the day, only the charger was damaged but nothing happened to the phone or it’s battery as I’m still using the phone and haven’t replaced the battery.

So you shouldn’t try it at all.

Aside from Facebook app, both the messenger app, Skype, and pinterest app tends to warm the phone when charging.

So what I usually do is to restrict these apps from running in the background, or probably turn off my Wi-Fi or cellular data when charging my phone.
