[SyedTalib27]

I have Xperia m with jelly bean 4.3.The battery lasted very long while using 2G but recently i have moved to 3G and i find that the battery is draining very quickly it only last half of the time when compared to 2G,does this happen to all

3G will drain faster than 2G,especially if network signal is bad.

On The first day i used 3G it lasted for a quite long time but that day my phone has died due to low battery from then the battery life is reduced

You should check if the same occurs in safe mode:

I wonder if the battery has been damaged.

[SyedTalib27]

How could i check if the battery is good or not, If the battery is damaged could i get it replaced under warranty as this phone is only 3 months old?

I had fully charged the phone and after 7-8 hours of stand by with out data connection it drained about 20%of the charge.This is not normal,am I correct?

[_alexdon_]

No,it is not normal.But beside data,were any other apps on?

[SyedTalib27]

All apps were closed and the data was also off
