This apps drain my battery faster than usual.. Even when i switch of wifi and data, its still draining battery faster.. I usually off data while im asleep.. and on data on next day morning for whole day.. what i can say is my battery cant last me one day.. T.T

Better but not good enough. It still drain my battery even when im offline, unlike whatsapp. If it drain during online and dont drain during offline then im ok with it.

Battery drain even when im offline.. i fully charged my phone at night and off data, switched to 2g only, off wifi and everything except calls. I woke up on next morning its 90% left. it should be 99% when i wakeup, that is before i install viber. What i mean is, viber should save battery when im offline even though its running in the background. Like whatsapp
