Xperia z2 battery drain issue

[spatra]

Hi, i've recently bought Xperia z2 but right now i'm having severe battery drain issue. At the first day it showed me average time of one & half day but right now its draining much faster & i'm only getting battery life of 13-14 hrs, only using wifi & music app. stamina mode is active but still no progress. any suggestion how to reduce battery drain? i've seen some post in this blog where people said they are getting battery life of around 4 days. Looking forward for a solution ASAP. Thanks.

Having WiFi on will reduce your battery life, that's normal.

This should help you understand how Stamina mode works

You should also check the Battery usage section, this will give you more indication as to what apps are using the battery life.

Menu > Settings > Power management > Battery usage
