if your still running 6.1, then there might be alllooot going into the updates and such, the longer a specific os is running, the more updates it downloads afterall.

Unfortunaty to say... the best advice I have for you is to probably do a hard reset.
It will clean up all the old updates and only download the most recent and needed ones, for the most part that is.

If you dont have that many apps or pisctures.. then thats the only thing I could think of it being.

If you have a storage card id transfer everything over and just reset it.

Have you concidered upgrading to 6.5?

I personaly think that it runs alot smoother then 6.1
I couldnt stand 6.1. now I cant really stand 6.5 now that im running 6.5.3 lol
go figure
