How to improve iOS 4 performance on iPhone 3G
If you update to iOS 4 on an iPhone 3G the performance, to but it mildly, will be poor to the point of frustration. When I first updated mine it was so bad I didn't want to use it -- though admittedly I'd gotten used to an iPhone 3GS, then iPhone 4, and it's never easy to go back.
iPhone Forums and stoovie to the rescue. Turns out there are a few things you can do to make it faster to the point of livable:
- Turn off Spotlight. Go to Settings, General, Home Button, Spotlight Search and just turn it all off. iPhone 3G is so resource constrained Apple wouldn't even enable wallpaper. Indexing Spotlight in the background seems to be the straw that breaks the performance's back. With Spotlight off, it's a usable device again.
If you're still having trouble there's always the nuclear option:
- Restore as a new iPhone. Do a clean wipe and re-install without copying back your data. It's a royal pain in the apps but there seems to be something borked about including old data that just slows stuff down. I got an immediate speed boost with a clean install as well.
Unfortunately, it's Jailbreak territory if you want to downgrade from iOS 4 to iOS 3.1.1 again, and many users seem to have problems even with that method. So try the above methods first and let us know how they work for you.
[Yeah, my iPhone 3G has a cracked screen but that's totally unrelated to the performance issue, poetry aside]
