“If the phone is in normal use without playing games or calling for long time, the temperature should be around 37°C or 38°C. But if you use your phone to play games or surfing internet for a long time, it will be normal that the temperature rises to around 55°C.“, official statement from HTC.
I was worried after discovered my HTC One X is overheating up to 53.5 °C. Consulted HTC Support. Was asked to do a battery test. And found out that my HTC One X battery is performing well. So I double confirm with HTC Support again. And got the statement as above.
Is HTC One X overheating an issue? Look like this is not an issue at all based on HTC statement. As you can see in the video, HTC One X temperature can easily go up to 50 °C after 10 minutes of playing NVIDIA Glowball Demo (from 33.5 °C at standby mode). And hover around 54 °C after 15 minutes. Wow… Can you imagine how hot when you touch the screen and hold the phone at 54 °C?
Hardcore gamers and Internet surfers, do take note on this. HTC One X is hotter than you thought.
