List<contact> ConList = new List<contact>();

contact pe = new contact();
pe.id =  '0032900000QsV17';
pe.phone__c= false;
ConList .add(pe);

contact pe2 = new contact ();
pe2.id =  '0032900000QsV17';
pe2.phone__c= true;
ConList .add(pe2);


Database.SaveResult[] srList = Database.update(ConList ,false);
System.debug('srList===' + srList);
