I upgraded my 920 to WP 8.1 update one developer preview last month. But its battery was still better. So how will Denim enhance the batter of 930? Although Nokia device are famous for horrible battery when intially launched, after couple of updates, its battery improves. I have experienced this with Lumia 900, 920 and now 930. Dad's 1320 is an exception. But it is because of the huge size.
You just contradicted yourself . Like you said, updates sometimes improve battery life, and Denim is a (firmware) update. And if any kind of update is known for improving battery life it is firmware updates, because firmware can change the way the phone's hardware and OS interact with each other.
But weird that you said that the DP got you the same battery life since it is known that the DP previews are terrible for battery life, which I experienced too with my HTC 8X and Lumia 920.
Switching from my L920 to my L930 did actually even felt the same as updating my L920 to the DP of windows 8.1, which was terrible for battery life. Lumia cyan brought it back to normal as expected. That's why I think Denim can solve the problem a bit. Not that I am on a DP, but maybe WP 8.1 update 1 and cyan create bugs in in some ways that are only to be resolved with Firmware, thus Denim. But we'll see.
