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. :D

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? :p

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?
 
Lol. Take apart your iPhone. You'll see what I mean. The internals are less thick than the metal band. So....the new phone is as thick as the 4 metal band. It's not hard to put 2 and 2 together.

The display on the 4 rests on top of the metal band. Add to that the glass rear, also resting on top of the metal band. The 5 no longer has a glass rear, therefore no glass resting on top of the metal band. And the new display rests flush with the metal band, rather than resting on top of it. So now the entire phone is just the metal band, with display and back cover flush with the metal band.

They might have saved a little room with the new in cell display tech, but the real magic lies in the way they designed and engineered the new unibody.

You win, I give up.
 
That is impossible especially with the 4s, do you charge it on the car as well?
I use my iphone 4(better battery life than 4s) for music,gps,internet,few calls and well when i return home it needs charging or it will off.

No, I only charge it at night. Obviously, it's not impossible because it's my daily routine. The one thing that really kills my battery is the GPS when running. That easily takes 25% off my battery. But music, phone calls, basic internet browsing combined is maybe another 20%. I do, however, reset the battery meter every 30 days as Apple recommends by letting the battery completely drain before recharging.
 
Who would of thought? Another incremental battery upgrade. Let's make a phone that can make it a whole work day.
 
No, it didn't :)

What I'm saying is that it's implied since it can be calculated easily. Maybe the article should also mention that those watts/hour and voltages have X mAh so we don't have to do the division.
 
i dont think you understand how apple operates. sustained incremental improvements. over years. thats how they roll.

Nice try but you are very wrong.

I have been an Apple loyalist, user, and shareholder since 1991.

I follow Apple very closely, have tens of thousands of dollars of Apple laptops, iPads, desktops, and iPhones... I know Apple very well.

Yeah youre a real cool guy. Everyone likes you now that you said this.

welcome to the party. still, you dont understand how apple operates. sustained, incremental updates over many years. i dont even need to cite examples because theyre all around us.

It's more useful to have mAh ratings; most places top-end blogs would do that maths for us.

I'm quite capable myself, and I won't be purchasing this phone anyway :)
 
The iPhone 4S doesn't last for more than 5 hours under my typical usage scenario of basically just browsing the web, so I doubt the iPhone 5 with its LTE will be suitable for my needs.

Ouch... I didn't realise the difference between iPhone 4 and 4S battery was so great. I'm actually considering hanging onto my iPhone 4 for the next year unless the iPhone 5 really blows me away (which is looking less and less likely).
 
Any dock worth a damn has a AUX line out for the headphone jack. The factory Apple one certainly does.

Line Out is NOT THE SAME as a headphone output. Line Out has no sense of volume control. Try it for yourself, plug your headphones into the Line Out of a dock and you will notice that the iPhone doesn't even let you set the volume. The reason for this is that Line Out is meant to go to something else that controls the volume (like your stereo system, car audio system, etc.).
