Battery Drain / No Deep Sleep In Flight Mode

[deja-vue]

Hi Folks,

Usualy i turn on flight mode and charge my phone when i'm going to bed.
Last night i forgot.

My phone lost about 10% battery ober night in flight mode, because it was active most of the time.

How an i find out, which app causes the activity?

Regards
