Pebble watch down to 50% after first day. Is this normal?

Hello.
Just yesterday I brought a Pebble Watch and a copy of talk2watch pro. I have found that after the first day of use my pebble has gone down to 50% battery life which I feel does not match the 'days' of battery use that is advertised. I'm wondering if it may have something to do with how I'm using talk2watch. I keep it on all day so that I can get notifications and control my music.
I would appreciate any help or advise.

I've noticed that with the lately. Not sure if it's the pebble firmware or my os, 10.3.1.1154 on z30.

I've read that it's a 10.3.1 Bluetooth issue. 10.3.0 is the latest good one for us Pebblers.

So can we load the older (10.3.0) bar file for bluetooth on the 10.3.1.1154 leaked Z30 OS?
I have no clue how to achieve this if so!
