IOS 5.0.1 should help users who are experiencing battery drain issues

Many users have been complaining about poor battery life ever since upgrading their iOS-based devices to iOS 5. Even users of Apple's brand new iPhone 4S have complained about not being able to make it through an entire day without recharging.
Apple released a beta of iOS 5.0.1 to developers last week to address the problem, and today the final version is available for customers to download. According to Apple, the following issues are addressed:
  • Fixes bugs affecting battery life
  • Adds Multitasking Gestures for original iPad
  • Resolves bugs with Documents in the Cloud
  • Improves voice recognition for Australian users using dictation 
CNET is reporting that Apple also snuck in a fix for the latest iOS security breach discovered by Charlie Miller.

Charlie Miller's Codesigning Exploit Fixed
By ltcommanderdata on 11/10/2011 2:26:48 PM , Rating: 4

Impact: An application may execute unsigned code

Description: A logic error existed in the mmap system call's checking of valid flag combinations. This issue may lead to a bypass of codesigning checks. This issue does not affect devices running iOS prior to version 4.3.


CVE-2011-3442 : Charlie Miller of Accuvant Labs

Looks like the security flaw has been fixed. I don't suppose Charlie Miller will get his developer account back now?

According to CNET, he's banned for a year from reapplying for the developer program.

A few hours after the news broke, Miller received an e-mail from Apple noting that his developer program access had been revoked for a period of one year for violating its terms of service. He called the move "heavy handed," noting that Apple gave security researchers free access to the dev program for the purposes of discovering flaws.

Hmm. At least he didn't lose any money since Apple provides dev accounts to security researchers for free. I guess Apple should have been more clear that they have no problem with security researchers tearing apart their code, just don't make proof-of-concept apps live on the App Store. Given Charlie Miller's well known credentials as a legitimate security researcher and that this is the first time this type of issue has come up with security researcher dev accounts, I think a stern warning and an official statement on what security researchers can and cannot do with their dev accounts would have been better than a year suspension.

Putting the exploit in the App store was just dumb. The guy is obviously sharp (he finds security holes in OS code) but what an idiot. He had to have known he would get banned Im guessing he did it on purpose for the publicity.

He probably did know that Apple wouldn't take too kindly on putting a proof-of-concept app on the App Store. However, he had to find out whether Apple's review process would have caught the exploit. No doubt this has made Apple toughen up it's app/code review policies, which is probably the longer lasting security improvement than just patching this individual security exploit.

Well also remember he notified Apple beforehand and they refused to listen. So he took his proof-of-concept to the next and guess what it PASSED the approval process and got out into the wild.

You are mixing two different events.

In an earlier exploit he notified Apple. They basically ignored him for quite a while, then *eventually* fixed it. IMHO Apple took *way* too long to fix it. It was almost as if Apple was saying to the world, we'll get to it when we feel like it.

This time around, he just clandestinely submitted it to the App store for publishing that had inappropriate code in it. Apple didn't catch it and allowed it to be published in the App store. After it was published he announced it had inappropriate code and processes in it.

Even he has said that while Apple's action was harsh (and IMHO over the top), that Apple was perfectly within their rights to banish him.

Stupid. You show sales figures to argue a battery life glitch. I own the 4s now (dumped my wp7) it is a great phone. It has(d) a battery life problem (fixed now i hope). The fact that a billion of them sold does not change that fact.

Even with that reasoning, your links have nothing to do with this thread and the article.

BTW the update seems to have fixed the Battery issue. I was at 100 percent this afternoon when i updated. Moderate usage today with everything turned back on and brightness up shows 70% after 10 hours. Huge improvement I was dropping 10% an hour before with any usage.

Maybe my ipoop will last for more than 2 hours of use and 2 days of standby.

Oh F*** it.

I'd wager my entire next year's income that you don't even own an "ipoop".

I've been disappointed with the battery life of every "cell phone" I've ever had. Every one.

However, if your entire talk time on *any* phone is only two hours you should dump it that same day, get one that lasts longer and stop complaining!

Maybe I use my ipoop diffferently, but my battery life has been great. Better than my poop3GS, which I thought already had great battery life.

To be fair...

... most mobile operating systems seem to have similar problems. At least Apple have got this out pretty quickly.

Haven't there been android and WP7 releases that are supposed to address the battery use issue too? I only just got the 2.3.4 update for my phone the other week, and it's been released for a while now.

this is the primary reason I bough an iPhone 4S rather than an Android. Updates are too infrequent on Android. Bugs happen, 6-10 months to get a fix is silly.

Let's hope Android 4.0 and Google's "18 months of support" will fix this as I'd really like to use Android when I re-up...

You mean...

Not fixed
