Reports: Apple Looking Into Slow iOS 4 on iPhone 3G

Reports have Apple looking into performance issues with iOS 4 running on older iPhone 3G handsets.

Apple’s iOS4 mobile operating system doesn’t just run on Apple’s brand new iPhone 4: although the original iPhone has been left out in the cold, the operating system does support Apple’s iPhone 3G and iPhone 3GS devices (Although Apple has consistently noted that not all iOS 4 features would be supported on previous devices, one key differentiator being multitasking.) However, some iPhone 3G owners have been less than thrilled about the iOS 4 upgrade, claiming the new operating system performs poorly on the older handsets and substantially reduces battery performance. Now, according to the Wall Street Journal and other sources, Apple has begun looking into complains about running iOS4 on older handsets, particularly the iPhone 3G.

In addition to reduced battery performance, users report the iPhone’s interface is substantially less responsive, many applications perform very slowly, with even functions that are essentially unchanged with iOS 4 becoming sluggish.

Some users had been hoping that Apple’s recently iOS 4.0.1 update would address performance issues, but iPhone 3G users who were experiencing problems report no improvements. Some users have reported good results performing a complete backup and restore, rather than merely updating the iPhone’s operating system.

Since announcing iOS 4, Apple has been clear that not all features would be supported on older handset models, with the most-commonly -cited example being application multitasking. However, from a computing standpoint, the differences between the handsets are significant: the iPhone 3G packs jkust 128 MB of RAM and a 400 MHz processor; the iPhone 3GS has 256 MB of RAM and a 600 MHz processor, which gives it a substantial performance edge.

  2. James Issac at 7:09am 30th July 2010 well first i came to know about the iOS 4 Upgrade for iPhone 3G, but afterwards few frnds update it... ad got some problem regarding processing slower.... is there anything regarding this problem Apple is working on?
  3. Austin at 9:03pm 29th July 2010 Why doesn't Apple just let 3G users buy an iPhone 4 at a reduced price?
    1. ioman at 4:42am 30th July 2010 Wait till your contract is up and then get a new one. Does Sony let you buy a new TV at a reduced price when you get bored with your current one?
  4. Jarrod at 8:47pm 29th July 2010 Yea didnt work for me either still very slow.
  5. Salsero777 at 7:52pm 29th July 2010 Hello - Performing the Jeromy fix has worked for me.
  6. Jeromy Manuel at 6:29pm 29th July 2010 This has greatly fixed my 3G: go into settings-general-home button-spotlight search, then uncheck everything you see there. Then hold down the home key+sleep key until you see the white Apple logo (ignore the slide to power off option). This should fix your sluggish issue with the 3G Please verify and update your article for others?.
    1. Dan Gaul at 7:02pm 29th July 2010 Hi Jeromy, I'm trying this now. I have a 3G that is horribly slow after upgrading to iOS4.
    2. Randy Donabedian at 7:56pm 29th July 2010 Yeah I did what you said, and it still lags majorly!
  7. Mark at 6:18pm 29th July 2010 as the others have said, iOS 4.x sucks on the 3G...
  8. ioman at 5:56pm 29th July 2010 Bad battery life on iOS 4 and 3G/3GS iPhone: I know a few people that claim their battery life was drastically hurt by the update. Some here lucky to get an hour between charges.
  9. Corey at 5:33pm 29th July 2010 Downgraded to 3.1.3 from 4.0.1, and my 3g is back to normal. Apple needs to provide an official manner to downgrade...iOS 4 should not be loaded on 3g.
  10. spellcheck at 5:29pm 29th July 2010 Mind your typos, there, Geoff. "Battery," not "batter." Otherwise it's a great article.
  11. Ghoulish at 5:27pm 29th July 2010 I really wish my contract were up. iOS4 has turned my awesome phone into a piece of crap.
  12. Ken at 5:21pm 29th July 2010 My 3GS runs substantially slower with IOS4. The camera shutter lags, lookup of email addresses is slow. Keyboard input is very very very slow... Not impressed at all. Love my iPhone, hate IOS 4
    1. dan at 9:46pm 29th July 2010 go on the web and get OS3 and reinstall it. I just did it and that solved my problems
