Apple: iPhone battery issue due to iOS 5, fix coming

Apple has finally broken radio silence over criticisms of lackluster battery life affecting iPhones old and new since releasing iOS 5 last month.
In a statement provided to AllThingsD, the company said it's aware of the problem and plans on offering a fix in the form of a software update.

"A small number of customers have reported lower-than-expected battery life on iOS 5 devices," Apple told the outlet. "We have found a few bugs that are affecting battery life and we will release a software update to address those in a few weeks."

As noted last week, users have flocked to Apple's support site to complain about lower than advertised battery life on the new phone, which went on sale in mid-October, as well as on Apple's previous models.

Affected users say fully-charged devices are running out of juice during the course of a workday, even with minimal use, a problem that was not present on their devices before the iOS 5 software update.

So far, users have scrapped together a number of solutions, from turning off software features, to turning off the device itself. But reports on success have been mixed, with some users experiencing more battery drain than others, and some even reporting battery life improving since updating to iOS 5.

iOS 5 spent a considerable amount of time in near-public testing before it was delivered to users. The software, which Apple says adds more than 200 features the previous version of iOS, went through seven beta versions for developers inside a four-month span.

Unlike its predecessor, the iPhone 4S is the first to sport a dual-core chip that can pump out what Apple says is twice the performance compared to last year's model. During the phone's unveiling last month, Phil Schiller, Apple's senior vice president of Worldwide Product Marketing, suggested that the company had not only matched the battery life of the previous model, but beaten it in some cases.

As BGR reports, Apple has already released a beta version of the updated software to developers, dubbed 5.0.1 that "fixes bugs affecting battery life," as well as bringing multitasking gestures to the original iPad, improving voice recognition for Australian accents, and fixing bugs with documents in Apple's iCloud. Not mentioned is an echo that's affecting some iPhone 4S owners who use a wired headset when making phone calls.

My 3GS is jailbroken, plus iOS 5. Battery dies in a snap.

Ik the battery life normally would be slightly less then the 4 due the new A5 processor, but it shouldn't drastically drain like that. Some users I heard also found they had reduced battery life on their iPhone 4's. So I am pretty positive it is a iOS 5-related issue,

Iphones uselly ran ok with the battery

Yea. iOS 5 may be cool, but it seems they still have a ways to go on optimization before it's ready.

Also, I doubt the dual core CPU is the culprit for reduced battery life. My Droid X2 has a dual core that's over twice as fast as the original Droid X, yet battery life remained the same. It's all about how you write the software to take advantage of the chip.

Apple claims it will have the opposite effect Oberst, which if you think about it, could be true. Newer CPUs have more transistors, but they usually consume less power. Of course, that's the desktop CPU's history, but the same can be said of the mobile chips. Most reviewers believe it's a software, not hardware, problem (specifically with iOS 5). The perils of being an early adopter.

as stated their are andriod phones with daul core processors that work fine

i have a droid x2 as well fastest phone iv ever used, lasts all day even under pretty heavy use, honeslty if i rarly use ti all day its still at like 70-80% at the end of the day

Kinda redundant to repost. I was pointing out to Oberst APPLE'S CPU shouldn't have an issue with the battery that has been going on. Plus, you can't say what works for one phone works for the other. Your Droid X2 phone uses a 1.0GHz dual-core nVidia Tegra 2 processor. Apple's iPhone4s uses the 1.0GHz dual-core A5 chip, the same one used in the iPad 2. Different CPUs, different architectures, different OS'es. Oranges to apples.

Now battery life compared to phones, which is longer. There's a comparison you can do (debating the cause of longer battery life means you have to point out the differences between the hardware).

Your DroidX2 only got about 4.25 hrs of life under web browsing use, so I don't know what you consider to be heavy use. Phone calls alone all day doesn't necessarily tax the battery compared to web browsing or games on the phone. Try watching one of those youtube videos of something for 8 hrs and see how long that'll work. That's heavy use to me (consistent internet usage of streaming video).

P.S. Slow down your typing, and you'll have less spelling mistakes. :thumbup:

I don't understand how you can have full control of both the hardware and software, and only have 5 devices, and STILL have crap like this.

Every single launch it is something.....
