Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

Thanks for the replies.

At first I did not use a proper 3.3 v regulator but now I have a LXDC2SCAAB-352 buck boost - magic !!
Now the readings are more stable since the ADC ref is also stable .

ADC input almost next to RF pin , not the best place but then the die is so small that even pin 16 is close to the rf circuit , external filter and cap close to input pin does help since the current in the batt voltage divider circuit is normally very small .
