eDRX / PSM mode always on?

Question

So I have a question about the nRF9160 when enabling the xDRX or PSM mode. Does one just turn the option on and leave it on eaven while uploading data or do you turn it off each time you want to send some data and communicate with a socket? 
 lte_lc_psm_req( );
lte_lc_edrx_req( ); 
 And do you need to request it again after sending data?

Hi Eirik, Please take a look at the Asset tracker sample, more specifically the " Power Optimization" section on how this can be achieved. 
 AT-commands reference: 
 
 PSM 
 eDRX 
 
 e.g. For PSM this is something that you enable once, and you should not need to disable the PSM if you don't want to stick with the data for all the parameters set to the default "manufacturer-specific" values.
