D5 should I do the OTA update

today I have the version 160310 and every 3-4 days there is a notification that there is an OTA update available.
The only problem I have is the 2g connectivity, which stopped after a while, so I am not accessable. With only 3g everything is ok.
My battery lasts for about 18-24 hours with 3g and wifi on ( depends on 3g signal ).
My question : should I update to the newest version 160929 ? Are there any advantages with this newer version ? Or should I leave it as it is ?

if it is minor bugs update, then NO, only if it is big and will improve saginificantly.
