Beetle BLE uses too much power..

I have bought three(!) Bluno Beetles for battery powered projects. They seemed very compatible with wearable battery powered projects. And it would make sense because the Atmega 328 aswell as the CC2540 have sleepmodes in which they consume only very little amounts of power. However after reducing the power of the Atmega 328 the Beetle is still consuming more than 10mA! How can I reduce that? According to texas instruments the CC2540 has many sleepmodes in which it consumes only a fraction.
Is there anyway I can reduce the power consumption in my project, maybe by:
a) Powering the CC2540 off/on with AT Commands
b) Powering the CC2540 off/on via code
c) Enabling a LOWPOWER mode in the Beetle?
d) Making use of the existing sleep modes of the CC2540, is there any way i can program the CC2540 to use a sleep mode
I am guessing the CC2540 is programmed somewhere, it has to be. Maybe in the firmware? Is it possible to change the firmware source code to enable sleep mode??
It is really disappointing, because the Beetle seems to be advertised for these kind of projects. But it just uses way to much power. On my 650 mAh battery it could barely last two days..
Maybe another way would be just disabling the 3.3v supply for the CC2540? And enabling it after a timer delay.
