To all of you: you're all wrong. The fact that it has a dual core should improve battery life in many circumstances and that dual core is also a newer architecture which furthers that. The problem is that some are getting great battery life and others terrible battery life. I'd hardly call that a hardware problem.

To FtL1776: the iPad 2 didn't get a bigger battery. The original iPad used two batteries and the iPad 2 used three thinner batteries. The iPad 2's battery is 0.1Whr more than the iPad's original battery.

The original iPad had an LED screen?

We all know that isn't true but: why would they do it to the new phone as well? This is just a bug which will be fixed soon enough.

Uhhh.. Steve Jobs AI in iOS5 being Steve Jobs?

Lol, Seriously though, How bad is the "battery drain"? I'm charging my phone once every two days. <.<

Typical iPhone user then.

I use my HTC Desire all day with Oxygen 2.3 and have 70% battery at the end of the day. The battery life on Android isn't actually that bad at all, it's just the HTC Sense rubbish that makes it barely last 6 hours.

I don't suppose you can tweak CPU governers and voltage on the iPhone via jailbreaking like Android phones. Can you?

Last I checked, on OS 3.x and on the iPhone 3G, you could. Nowadays? No idea.

And yeah, betting this problem is Siri, or some easy software fix.

This times a million.

I've lurked and finally became a member of macrumors for their expansive iPhone section and it's exactly true, some people with every last thing enabled get 6-8 hours as they should, others can barely break 4 hours with everything disabled... seems like a serious hit and miss issue with iOS5, not the hardware.

Though, some people have said they exchanged their 4S at the Apple Store, and the replacement has better battery life, now that *could* be the hardware, or just a better software install. I'm still voting for the latter.

I for one reinstalled iOS5 on my 4S, set it up as a new phone, left what I needed enabled, roughly half of the stuff, and I'm hitting 7 hours, almost 8 with good usage and plenty of Scribblenauts. Before the reinstall? I couldn't get 5 hours ever if I played anything, let alone had anything enabled, it was terrible.

Last little tidbit, the article from cNet refers to the Guardian's user post:
Quote:
My battery life was extremely poor – 10% drop in standby every hour. I noticed that the usage figure was roughly half that of standby, even when the phone was not being used, so I assumed something was crashing or running in the background. I switched off all the new features including Siri and location services, but it was still really poor. I also tried setting up a clean phone with no apps but it is still really poor.
This from RedmondPie sums up my thoughts:

According to the same person, Apple then got in touch with him via phone, where an engineer admitted that the company is aware of a potential issue and that, worryingly, they are not close to a fix.

There are two things about that story that don’t quite add up. First, why did Apple get in touch with this one person? What was so special about them? The story doesn’t say that they got in touch with Apple first.

Secondly, it’s not like Apple to admit any kind of issue, especially if they don’t have a fix in the pipeline.

I've seen people doing that with iPads too, and quite frankly, I think they just look like drones. Marketing tools.

I figure I may as well do it here: Welcome to MacRumors =)

I did a fresh install right off the bat, and I'm pretty happy with my battery life. I get about two minutes per percent with everything enabled and on max brightness whilst playing Infinity Blade 2.

Siri apparently forgets to turn off lights and appliances, from time to time.

A4 power consumption is estimated to be 250mW ~ 520mW.

and everything that I can find says that the A5 has roughly the same power consumption because they cut the speed of both cores to 800mhz in order to preserve the same power consumption.

Edit: fixed the number typo
