The A5X chip will help with battery life so I don't think it'll really suffer. Should be a lot better when you're not using LTE as well.
I'm really hoping there will be the option to turn off 4G/LTE.

Of course you will. You can do it on the retina iPad.

Speculating on battery life is a bit pointless without knowing the power requirements of the 28-nm lte and low-power broadcomm wireless it will likely use. But I doubt it'll be worse than the 4S.
 
LOL, If the phone has LTE.... I am not so sure anymore (assuming this is the battery for the next iPhone). Either way, I feel there is a possibility I may fall into the category of someone with an LTE phone that never uses it.

I don't see why it wouldn't. Remember, it's not an iPad and doesn't need as large of a battery.
 
Everyone forgets the 32nm A5 gave iPad 2 two extra hours battery. Most likely, it will the 32 nm A5 in the new iPhone (or something similar to the A5-main thing is 32nm). The Gobi LTE chip is 28nm and about 20-30% more efficient than than the chips mentioned by OP. IGZO display is 30-40% more efficient.

I'm sure we'll see 6 hours LTE browsing, 8 hours 3G, and 9 hours Talk time.
 
People please

STOP MAKING ASSUMPTIONS ABOUT LTE POWER USE!


Rather than create idiotic "hand waving" threads about phantom issues why don't you do a bit of research.

There are multiple reasons why the next iPhone can improve battery life.

1. LTE phones in 2011 required 3 chips. 3G+Voice and LTE. That's now a 2 chip solution in most cases (MDM9615 I believe)

2. I don't think Apple uses a die shrunk A5X. I believe they'll either use a 32nm A5 variant in a dual or quad core configuration with more power saving modes.

3. iOS 6 should be more efficient in managing battery and components.

I hope you are correct with that one... I remember the few days with my iPhone 4 before I bought my 4S... The iPhone has such good battery life, I charged it everyday, but I could make it the entire day without a recharge. iOS 5 decreased its battery life slightly, but it was still better than the 4S.

My only worry is this... With every new iPhone, the battery life improved. Even if it was only slight, it did, at least it did for me.

ADDITIONAL: With the updates to iOS 5, the iPhone 4 may have regained battery life.
 
Keep in mind it's not an Android device. It gets better battery life than Android devices with 2100 mAh batteries. THAT'S a joke.

It's 4g. I don't get the hype, as I'd rather have battery life then not have to wait three extra second for my internet. But some people swear by it.

People need to think about this like they are an engineer. You have a design goal and are entrusted to deliver improved specs within the parameters of the battery chosen for the design.

I don't think Apple had the efficient parts last year to go dual core in a phone and not have a battery hit.

This year I expect that 28 and 32nm parts will allow for the next iPhone to improve battery life over the 4s.

We'll have at least a dual core but it'll be fabbed at 32nm and not 45. That's a nice die shrink! Then you move off of 40nm baseband and broadband parts for more power savings.

Finally if the next A5 or A6 SoC has some secret sauce it could further reduce battery consumption.

Finally iOS 6 should be better at managing resources.

I don't see any reason to fear. Apple adding LTE doesn't suddenly tip the cart here.
 
they wont release a phone that gets worse battery life than the 4s. calm down everybody.

YMMV. Plus, that image is showing battery on calls, not actual usage with apps, music, etc.

I've never owned an Android device that could get more than 3 hours of usage / screen-on time.

HTC EVO 4G: 1500 mAh
Nexus S 4G: 1500 mAh
Epic 4G Touch: 1800 mAh

iPhone 4S: 1430 mAh battery, easily gets 6 hours of screen on time.
 
silly iphone users.


here is their mentality:

  1. denial
  2. put other products down since they are not superior
  3. acceptance with making everything else look same as iphone and saying well my iphone can do XYZ....



Before SIRI:

iPhone user: Who uses Voice commands

After SIRI:

Our voice commands are superior to Google's
 
i'm glad you posted that b.c I was going to say, I get better battery with my 4S than I Did with the S3 which had a much bigger battery. By better, I mean A LOT BETTER.

My 4S battery life is heavenly compared to the android phones I had before.

My Sprint GS2 had an enormous battery and it was still down to 50% after a couple of hours web use.
 

Note that Galaxy S3 uses the 28nm LTE parts as opposed to the One X which uses 40nm and you can see in the chart the effect.

If the next iPhone uses 28nm (which is likely) we should see a bump in battery life because most of the other chips will become more power efficient as well.
 
No, they wont. Lateral move at worst.

And the 4S holds its own very well.

That is cool to see, I know my 4S has WAY better battery life than the GS2 I had for work did, now I just have a black and a white iPhone 4S (work and personal).

But I know my iPhone 4 lasted longer throughout the day than my 4S does.

Same goes for me with the GS2 I had.

True, we have 4 iphones in the family, plus a few Mp3 docking stations.
All needing adaptors :(

Yea, I will feel that pain. I have a car charger, a "from factory" iPod hook up in my car, several extra chargers (bedroom, living room, work, travel), and my Bowers and Wilkins Zeppelin Air... So I know that pain for sure.

But I still think they needed to change the adapter, so I am not upset. I will probably only buy 2 adapters... one for the iPod hookup in my car and one for my Zeppelin Air.
