This phone is a great product. Value for money paid. I am using this for last 02 months. Now writing reviews. No issue of battery draining. 2 battery save modes, excellent performance. Extreme power saver reduces battery only by 2% in 8 hrs.Other mode by 5% in 8HR span. Software is great. No complications. Task killer on direct access. No need to download external programes and user privacy is respected. . 3GB ram sufficient to handle any number of programes. Beautiful, Stylish, handy, compact smart phone and one of the best phone available in the Android market. I give a score of 4.8 out of 5.
