Yes, within the same processor generation, the faster = more power hungry rule applies, but once you change processor generations or fabrication processes it does not.
If only we had a processor family change in recent history to use as an example (like say the P4 to Core Duo) to disprove this claim.![]()
Like the from Core i2 Yorkfield to Core i3 Ivy, going from 65W to 77W a roughly the same speed?
But they are more complex now - this just proves that it could go both ways.
The screen's (rumored) technology is also thinner, and passes more of the backlighting through to the user. This means greater efficiency because it uses *less* light to get the same effective brightness.
This will probably be a net battery life *gain*, despite the larger screen.
When comparing the same size, yes - the added real-estate will consume relatively more power, but it might be some gain overall.
There's a reason Apple waited for the current generation of LTE chipset. The first generation was miserable for power consumption, *and* still required a 3G chipset as well, making matters worse.
Or that LTE wasn't in the US yet - the "new iPad" proved that Apple doesn't know much (and doesn't care) about what's going on south of Florida.
Odds are, the announcement of the iPhone 5 will include a statement to the effect of, "all these great features, and still the same battery life", or maybe even a small improvement.
And that isn't much, 4S has disappointing battery life and it seems everyone else but Apple actually are improving this. So overall this is a letdown.
No, not necessarily. On the other hand, if complaining about it isn't actually going to have any effect, what's the point of wasting your energy?![]()
It's an odd compromise - having a bigger phone and having the internal capacity to increase battery life but instead shaving off 2 or 3 millimeters to benefit who?
