My Huawei IDEOS u8150 is new and ever since I used the AC charger that was supplied with it, my device gets a bit hotter (a noticable 5 degrees Celsius extra compared to charging via USB from laptop).
Why is it not that hot when I try to charge it through PC/laptop?
I hear a whirring noise from the AC charger always and the adapter gets a little warm too.
Also, my device charges faster on the AC charger compared to the laptop charge method. Is this normal on all devices in general? Or all Huawei devices? Or is this something faulty I should worry about?
