The phone comes with a single core 1 GHz Qualcomm Snapdragon processor coupled with a 512 MB RAM and Adreno 205 GPU. While it sounds a bit low powered, performance is top notch- there is no lag, no hanging issue.
Though if you start to open too many applications or play heavy graphics games the performance does slow down a little. It is better if you close down applications when you don't need them and thanks to Android 4.0 you can do so very easily.
The earpiece is loud and clear. Voice quality, mic and reception are all top notch. The loudspeaker of the phone is not very loud, though it is clear for sure. WiFi connectivity is very good too. In fact it got reception at quite a distance from the router where other phones were too far out of range. The FM radio reception however is not as good, but it is not disappointing either. It's just ok. We did not get the earphone with the review unit so we can't comment on that.
The 1500 mAh battery is decent and the phone lasts a full day with WiFi on for more than half the day, two hours of music and a good number of calls and Youtube videos.
