I think that its going to massively vary. They say theres much improved battery saving, but I suspect thats just in standby.
I cannot see that they will have been able to improve power consumption much when actually using these apps fully (wifi, bluetooth, GPS etc).
So in short, I reckon its going to last longer for those that dont use it much, if that makes sense.
Rough example - You have an
N95 (classic) with the same battery. I reckon, that with the exact same usage of apps and whatnot, the following would happen:
In light use, the
N95 lasts quite a bit less than the N96.
In heavy use, the
N95 has little difference in battery life.
I think for power users, its going to be a letdown.
And DVB on a 950 battery? Thats got to be a mistake. Unless of course, if you live in the UK.
