Battery is not 5000 mah. It may be around 2000 to 2500 mah.
Camera bad both front & back. Only screen protection is good. Resolution of screen is not good.speaker waste. Some time heats, phone is hanging when apps more than 80. It switch offs on it self. According to me in 5.1 android 1 GB ram is sufficient. We need at least 2gb ram.
