Hi. I bought the blue 8+256 gb for my mom she is complaining about the phone heating during charging used a 45 w charger and also complained when the phone was in low battery mode also , so I tested it by using a digital temperature it was 45 when charging and in low power mode it was around 43 it was on wifi and 3 apps open including YouTube, what should I do? Its on version 4.1 , please help. Charger was an 45w infinix, but when I charged using samsung charger 30w i think it didn’t reach high temperature it was warm
