Hi everyone .

I have been using S25U since 2weeks. I noticed battery drain issue while doing WhatsApp video call more. I'm

getting SOT of 5 to 5.5Hours. Otherwise I'm getting 6.5Hours of SOT.

I'm using HD option in display and kept most of the apps in sleep mode. Still I'm getting 5.5hours of SOT.

I have asked for a phone replacement and the supplier refused by saying wait for the update to sortout the issue.

Please someone help is this normal or I got faulty one.
