For tech/engineering gurus:

With the rumored changes in iP5- larger higher res display, 4G/LTE capability, it seems to me the power requirement goes up sharply.
The solutions:
Bigger battery-> heavier/larger phone
Shrink processor and/or modem to reduce power consumption-> Using a separate processor (A5/6?) limits ability to cut power.
Improve power management-> Doesn't seem like enough can be done to completely offset higher power needs
Integrate modem and A5-> Have not seen any rumors on this.

Any thoughts as to how this problem gets solved?

Dunno. I'm not the one who has to solve it. :cool:

32nm A5 allows for 2 extra hours on iPad 2.
45nm wifi chip saves 50% power and 3 orders of magnitude more power when in standby
28nm LTE chip 20% more efficient than current gen chips.

Longer phone = longer battery.

I think we will see an improvement in battery life over the 4S

Good reply Apple :D

No one knows, but Apple themselves, so we just have to wait.

I don't like my phone better than the 4s, but the htc one x's Krait chip solved all of these worries. Battery life is just as long as my 4s was with LTE running.

I expect apple to use a somewhat similar chip

Amazing!!

Five posts and no one has yet screamed "No, it will be iPhone 6"..."No, it will just be just iPhone".

Wonderful!!! :D

am i the only one who doesn't need LTE yet?

longer iphone with minimal screen size increase means more battery life, but i wish it stays with 3G because it's fast enough for a mobile use.

hope it stays with 3g and battery life like iPad, 10 hours of usage!

one can only wish but i think LTE is going to happen because the ipad has one.

They are going to make the iphone thicker and put a larger battery in it. The same thing they did with the ipad3

AFD: Thanks for the thoughts. Seems like Apple has some room to add res and processing power without compromising the battery life.
