Battery drain during Standby

After updating Z10 to 10.3.2
My standby time is horrible
If I leave my phone at 80% at night (11:30pm), then when I wake up at 7:00am battery drain to around 60-65%, I keep my phone at Airplane mode during night.

Please help

Have a trffic monitor app running? I know several traffic monitors which double their energy consumption when the network connections are switched off.

No I don't have any app like that
