Query: VERY LOW BATTERY LIFE

Well, I am not too happy with my purchase. Though the other factors are good, I dont like the time it lasts after charging.It usually lasts around 30-45 minutes before it completely gets out of charge, and thats full charging after more than 4 hours.Well I am not sure if its due the bad piece I have got or there are some real battery life issues. But yes when it works it is excellant, no problems with compatibility or connection problems or any other problems. Dont know what more to say but I wont suggest it.
