My phone is works fine with no issues, Games running smooth but when charging the charger gets hot (the phone not) , btw is that normal that my phone gets charged fast? (2 hours and It's almost full battery)
My Nexus 5 charges pretty quickly as well. Are you using the original charger? Mine doesn't heat up, but my 2013 Nexus 7 charger does sometimes. How hot does it get? Does it make any buzzing noises?
My N5 charger made a buzzing noise right out-of-the-box and also got very warm. I was too lazy to call Google so I just swapped it with another charger I had laying around. Try out another charger.
