iPhone owners might want to avoid iOS 5.0.1 update

iPhone owners might want to avoid iOS 5.0.1 update

Summary: If you've not yet installed iOS 5.0.1, you might want to give it a miss.

Last Thursday Apple released iOS 5.0.1 and I immediately installed it on my iPhone 4 (primarily so I could test out the over-the-air install feature). Then something happened that wasn't supposed to happen - my Phone's battery life took an instant and massive hit.

According to Apple, iOS 5.0.1 was meant to fix 'bugs affecting battery life' but according to user feedback over on Apple's support forum the update didn't fix the problem for many users, and introduced the bug to others who had previously not been affected by it.

Note: In the defense of the iOS 5.0.1 update, it did fix the problem for some iPhone owners.

I have first-hand proof that the iOS 5.0.1 update can be toxic - because my iPhone 4 battery life hasn't been the same since installing it. Prior to iOS 5.0.1 I was getting what I would have described as stellar battery life from my handset. Even when under quite heavy usage I could go a good day and a half without needing to recharge. Even after installing iOS 5, I was still getting excellent performance out of the battery.

Then I installed iOS 5.0.1 ...

The first thing that I noticed was the battery life dropping like a stone overnight when the handset wasn't doing anything. As a rule I'd expect a drop of around four percentage points overnight, but Friday morning after installing the new update I noticed that the battery had dropped about fifteen percentage points, way more than I'd have normally expected. I put it down to coincidence but decided to keep an eye on things. Next night I noticed the same thing happen. To make matters worse, I noticed the battery draining away much faster than normal during the day with no change in my usage pattern. Just this morning I saw the handset drop from 80% charge to under 10% over the course of a few hours.

And remember, this isn't a new iPhone 4S, this is an iPhone 4 that prior to iOS 5.0.1 update was offering me excellent battery life.

Testing done for me by an iOS app developer seems to suggest that the battery problems affecting iPhone 4S is software related rather than anything to do with the hardware, and given the issue I'm seeing on my iPhone 4 (and to some extent on my two test iPhone 3GS handsets), I'm inclined to agree that with that conclusion.

So, given that I've both heard and seen how iOS 5.0.1 can cause problems for iPhone 4 and 4S (and to a lesser extent, 3GS users), if you've not yet installed the update, you might want to give it a miss.

    Apple will soon patch the patch for the patch that was supposed to patch the original patch to the update.

      @toddybottom why not avoid iphones altogather. according to latest report on apple insider the gap between apple and rim in worldwide market share is only 1.2%. with new products rim will soon overtake apple. ipad is finished with the launch of new windows.

        I don't care if RIM sells more junk than Apple. I don't care if Windows phones sell better than iPhone. I had iPhone 3G for 3 years, then I got an HTC Evo last November. I am glad to be back on iPhone. This time 4S. I simply don't have time to deal with crap that becomes obsolete 3 months after release. Does that make me an Apple fanboy ?

    On my 3GS, I've noticed a vast performance improvement over 5.0 and the battery life appears to be about the same.

      @jcraggie Agreed, same here, but I do have a problem with mp3 playback stuttering in the Music app when switching between tracks using the double-tap to access the controls on the lock screen. This was in the bog standard iOS 5 though. Everything else feels a bit more lifelike, closer to the initial release of iOS4 before the performance improvements in later updates.

      I do have a habit of double-clicking and clearing the app history though. It can get quite sluggish otherwise, more so than iOS4. My battery life is no different than the previous release. I wonder if it's an app or a notification thing? I have most of my notifications turned off now...

    Not sure about the massive hit. Been running 5.01 on my iPhone 4 and there has been no change in battery life. Neither improved or gotten worse.

    • Agree.

      @zonapunk, My Verizon iPhone 4 is running like a top with 5.0.1, as it did with 5.0.

      Adrian, do you have the Verizon iPhone 4 or the ATT version?

        @Snooki_smoosh_smoosh Same here on AT&T, iPhone 4 with 5.0.1. Working great, as before.

      • Grrrrr

        @Snooki_smoosh_smoosh

        ATT and have an issue but generally only in standby - 4 16gb
        5.01 did not really affect battery - 5.0 was the killer

    I have a few users here with the update to their iPhone 4's and a few are having the problem. Doesn't seem to be much different configuration from the ones that are fine though? I told them it may be a while since its fixed since its so inconsistent on when and why it is happening. They weren't too happy to hear that and I get the brunt of their frustration, but I had to repeat its an Apple issue and Apple has to fix it. I have also told anyone with the 4 to not upgrade to iOS5 until there is some resolution to this.

    My 4S battery life really didn't get any better, or worse. It still sucks.

    My 4S seems to be getting better battery life, however I've had 2 or 3 mornings where it's on 97% after charging all night long and after calibrating the battery, so I may be contacting Apple to see if they can help me out with this. Perhaps a new phone.

  • A placebo fix?

    My money is on it all being a diversion from the fact that the 2G option has been removed.

  • AT&T iPhone 4 Battery Issue After 5.0.1

    I noticed the same thing, but it seems intermittent. Dropped 15% in the last 6 hours with very little use. Strange
