Default Weird firmware?

So I have recent got a RAZR HD here in the UK with JB out of the box and am having a few issues including poor performance and poor battery life along with the phone getting very warm when performing light tasks such as sending a few text messages. The other thing I have noticed is that the phone takes a very long time to charge. Around 3-4 hours.

Anyway, I have used better battery stats and narrowed down some wakelocks to what appear to be radio related things. So it got me wondering and I started looking into what firmware I have and I cannot find mention of it anywhere.

Can anyone shed some light on this as well as why it might be that I am getting some strange issues like performance. An example would be that music stutters when web browsing.

Anyway, here is a screenshot of my firmware etc:

I would list my devices along with current device here, but it changes too often.
