I am using multiple apps including my office email. I used old, maps, office email, gmail, whatsapp, facebook, One thing I noticed is that phone is not heating up.battery is on the lakeside interns of may. But I have a feeling that HTC has made it like that which should serve the purpose and the same time to avoid hearing.I am happy so far.reliance digital gave me a 16GB SD card and BT50 Bluetooth as well as freebies
