After posting on this issue, the problem was getting worse with each day. Hence I purchased a new battery from Flipkart and it arrived within 48 hours. Wow..what a relief. New battery is perfect and never seems to discharge. Taking long time to charge upto 100% and again the charge lasts almost two working days with my normal mixed usage of internet, wi fi, bluetooth, gps, youtube, email, whatsapp, viber, etc. Very rarely leave the phone alone. Display almost on all the time. @Shaleen: I do not know what is the profile of your usage but please remember a device with such a large display and features is bound to be a battery guzzler and drain out the battery with regular and extensive usage. Don’t compare with E71. that’s a totally different device. Even my earlier SE W830i battery lasted more than 2 1/2 years with fairly good usage of GPRS.
