sdk14.2 52832 consumption matter

i use sdk14.2 52832      i use uart

UART0_CONFIG_USE_EASY_DMA =1  consumption ~2.1mA

UART0_CONFIG_USE_EASY_DMA =0  consumption ~650uA

Is this a normal phenomenon, is it true that UART0_CONFIG_USE_EASY_DMA = 1 causes power consumption to reach 2.1ma?

If this is abnormal, how to solve it? 

Why sdk13 nrf52810 The same configuration as this example Power consumption test is very different,

when  UART0_CONFIG_USE_EASY_DMA =1  consumption ~650uA

why sdk14.2 52832 CONFIG_USE_EASY_DMA =1  consumption ~2.1mA 

I checked the forum, some people say that this is caused by the difference of sdk, if I want to achieve the effect of sdk13 52810 how to do

Is there no way to change it? I urgently need to solve this problem. If I try it, if CONFIG_USE_EASY_DMA =0 the transmission speed can only reach 4kb/s, more than 4kb/s will report an error.
The CONFIG_USE_EASY_DMA =1 transparent transmission rate can reach 6.5kb / s and above, I think the normal phenomenon should be CONFIG_USE_EASY_DMA =1 and the power consumption is ~600mA or so, I seriously suspect this is a bug, as mentioned above sdk13 52810 CONFIG_USE_EASY_DMA =1 Power consumption ~600mA is normal
