i didnt worry about it till today. but i was useing my phone while it was charging. but it got pretty hot today. enough for me to go download a app to see the temp of the battery. it said like 108? and right before i took at battery 118? idk if its right but it was pretty hot. and i am sure its not good if its getting that hot. i was listening music through blue-tooth, on the internet with wifi and thats it really. i put it in the fridge for 5 mins hope that wont hurt it but i need help and what should i do to stop this? please let me know. im using the charger that came with it. it was got warm when i charge before but i dont think this much.
