HTC India — Htc desire 626g plus dual sim battery backup very bad

Address:

Bardhaman, West Bengal, 713216

Since I purchased the mobile phone one and half months ago, I find that the battery charge is running out very fast.I have to charge the battery after about 20/21 hours everytime.It is absolutely not normal for a good quality smartphone.I have used smartphones earlier and have heard of many from my friends, and the fact is that once charged, it should long for at least 48 hrs. Moreover, when I purchased the phone from one shop named BABA TELECOM located in JunctionMall, City Centre, Durgapur-713216, DIST.-Burdwan, West Bengal, India, I had asked them to disclose all merits and demerits of the the phone, but they did not say an word about possible slow battery performance of the phone.So, I request you to take appropriate measures so that I get longer battery life.
