Want to ask any mi3 owner some question

1. How's the battery life? Heard that it's only average even with 3050mah battery.(screen on time? Talk time?)

2. Does it heat up very quickly when you game? I saw websites saying that it heats up to 40 degree when gaming and then the game will slow down(lag because they clock down the processor). I saw this case happened on tegra 4 version on some websites. Not sure about the snapdragon 800 version though..

3. Can the camera focus clearly?

4. When plugging in earphones(good quality and isolating ones), can you hear any loud static sound? Or any electric sound?

5. Is the touchscreen sensitive? Do you ever experience loss of word while typing?

This are some issues published on some website for mi 3..

Thank you!
