I got the phone yesterday evening, I think its been hot for the entire time, especially when on charge. Should I take it back for replacement or is it meant to be like this? If it breaks at aby time in my 24 month contract because of this can I get it replaced?
it is normal for a phone to overheat.. however if it overheats for 24/7 there must be something wrong.. my 9900 and iPhone 4S overheats when I use them a lot.. So I dont think there's anything to worry about.
You might have a small radiator leak, or check your radiator fans; you could also just be low on coolant/water. Make sure you're using the right oil grade, too thick or too thin viscosity is a bad thing. Also check to make sure your gaskets are properly sealed, at the very worst could be a blown head.
Oh wait, we're talking about a phone here...
Usually what I do is take the battery out, let it cool down, place it back in and turn on the phone. Then reconnect the charger, does the trick for me 99% of the time.
if that doesn't solve it, it could be an app that you downloaded/installed that could be running in the foreground or background that is running inefficiently and asking too much of the battery.
Press and hold the Menu key for a few seconds and see how many application are running in the background, generally five will always there ( Home, BBM, Message,Phone , Browser )
