My best of the three originals I have lasts all day with moderate use. The other two last til mid-afternoon or so. Note, I have always had most location and background apps turned off. I use Bluetooth on my car regularly, and that, calls, and especially maps/navigation drain it the most, and in that order (I usually plug in in the car, of course). The 950 feature I've always valued the most is indeed replaceable batteries. Thus, I do what I need to do, and never worry about battery life. Get one or two if you can and relax.
