So for the last 2 weeks I've busy experimenting and trying to obtain how long each phone lasts with music playback with different settings. You can see the exact numbers and conclusions here:
"Kentucky seeks to execute in a relatively humane manner and has worked hard to adopt such a procedure," Kentucky Attorney General Gregory Stumbo has said.
One thing that stood out was that when the N95-3 was on the network (as my phone is pretty much 100% of the time) that it played for almost as long as in Offline mode. The N95-1 didn't do so well in this area.
with the apparent improvement of battery life with the n95-1, i wonder how the comparison would look now.
Yeah, I spent two weeks with the older firmware...and now the new one is released. Pitty I can't crunch these numbers again because I already sent it back to WOMWorld. However I'll be willing to try them again in the near future and adding those numbers side to side to the existing ones.
If you guys would like I can make this type of testing in to a permanent "grid-like" chart, Similar to what Steve does for comparing smartphone features.

Guys and gals, I’ve just finished my multimedia playback battery life tests.
Exactly the same tests, conducted under exactly the same circumstances (static and same placement, disabled 3G, no Net connections / programs running in the background, no Bluetooth, lowest backlight; no incoming / outgoing phone (call, SMS etc.) activity; factory earbuds with 70% volume level and exactly the same set of WMA’s, in the same order) that yielded in 5:26 total playback time (from being topped up battery to the handset entirely shutting down) with the v12 ROM, now, resulted in 7:55 total playback time with the new, v20 ROM.
That is, the low-CPU multimedia playback battery life has been increased by 45% !!!! This means it’s true what the Nokia folks have claimed: that is, they have implemented far better scaling (underclocking) than in previous firmware versions.
I’ll repeat the tests with A2DP to see whether the improvements are similar, or, does A2DP result in a significantly less battery life gain.
