Hi,friends,RC, today,I'm taking with higher authority person via ASUS helpline number.
They told me that this drain issue in 98 is already send to developer team.
They asked me,what's are issue?
I'm told them that,
Battery drain fast

Any new major update like Nogout,becoz this handset launched with Marshmallow.
Also I requested to them that,
Some apps must be delete as
Mini movies,do it later,share it,photo collage etc.
