The only thing I don't like about the iphone4 is the low battery. When I travel, it's gone by 2 PM because I use the GPS a lot. I can abuse the iPad all day without worry and it would be so cool if the iPhone 5 was like that.
I don't think the IP5 is going to revolutionize GPS receivers by drastically reducing their power consumption. GPS receivers on all devices (iOS and otherwise) are power hungry.

Android is pitiful compared to Android
Really?

That's a neat trick.

Has the capacity of the new battery been listed? If people are just going off physical size, I'm sure in the past year and a half they've improved battery density a little bit. Also, the dual core A5 should improve the battery life slightly too. All the little things add up.

Yes

Actually the leaked battery is 0.5 Whrs greater than the iPhone 4's battery.

Actually, it's .05 Whrs difference. From 5.25 Whrs to 5.3 Whrs

I'm not really knowledgable in these areas, but I would like to think that a dual core processor would be more power efficient than the A4. By definition, this would mean a better battery life for the iPhone 5 then (assuming it gets the A5). Although... a larger screen might just offset that small power gain...

So not sure until Steve Jobs presents it to us! (Or well, Tim Cook... but really hoping that Steve will be there!)
 
That's what I said... It is .05 GREATER than the iPhone 4's (Decimal was f'ed up in op)

Yeah, just pointing out the decimal diff. I didn't catch it at first myself. (hence the edit)

In your thoughts, is .05 Whrs significant? I'm guessing no.

Unless Apple has really improved battery life with the new A5 chip for the iPhone 5, then no, in the grand scheme of things I think its insignificant.
 
It would make absolutely no sense whatsoever for them to release an updated and upgraded iPhone that has a worse battery than the previous one.

It could have a better battery but worse battery performance as a result of added features. The OP didn't mean they would put a lesser battery in the new iPhone.

Didn't the iPhone 3G have a worse battery life than the original iPhone? If yes then I worry that we might see history repeating itself.

History - launch a significant new feature (3G capability) but at the expense of battery life (the iPhone 3G) and then address the battery life issue the following year (the iPhone 3GS).

History possibly repeating itself - launch a significant new feature (bigger screen) but at the expense of battery life (the 2011 iPhone) and then address the battery life issue the following year (the 2012 iPhone).

I can't think that the A5 will save much if any power under low CPU load conditions which, unless you're gaming or watching video, is most of the time for most users and I worry that a bigger screen, especially if it's the rumoured 4" one, will add a fair bit to the power draw.

What could Apple do about it? Well, it's just possible that part of the reson for the delayed iPhone launch this year is to get an A5' chip ready that is basically an A5 on a smaller geometry (32nm?) and, if they haven't managed to get that into the 2011 release, then I think most informed commentators would be really surprised if Apple's 2012 lineup of SoCs weren't on a sub-45nm geometry; that's virtually a given in my opinion. Also, I'm no expert on display technologies, but maybe at the same time as going up to a bigger screen Apple might also manage to introduce some sort of power reduction technology to at least stand still if not actually reduce consumption in going from the old screen to the new bigger screen and again, if they haven't been able to do that in the 2011 timescale, maybe it might happen for the 2012 model.

No one knows, but on the assumption that the rumour of a bigger screen is true then I would be relieved and somewhat impressed if Apple manages to maintain the battery life, not at all surprised if battery life takes a hit, and very impressed if they manage to get any worthwhile increase in battery life (better than 5% gain) with a new model that features a 3.7" or larger screen.

Why do these type of threads always appear before the launch of every new iPhone? :rolleyes:
