iPhone 4 and iOS 7 - Trouble? How to go back to iOS 6

UPDATE: Read => http://www.mobot.net/iphone-4-ios-7-keyboard-lag-fix for the
keyboard lag fix.

There seem to be a few iPhone 4 users out there who regret the jump into iOS 7 waters - "UNUSABLE", they cry...

A couple of Mobot visitors reported "No issues" on their iPhone 4 oldies, but still...

It seems the main 'culprit' is serious lag when using the keyboard and a rapidly
depleting battery - with added heat generation thrown in for pure joy.

Not good at all.

So, if your iPhone 4 is doing well with the new OS, count yourself lucky.
If not (or if you hate the iOS 7 looks and features), head over to this fairly
clear guide on How-To return from iOS 7 to iOS 6.

If your old iPhone is borderline okay and you kind of like the new iOS 7 thing, you can do a few things to cut back on stress on the CPU and battery.

Background App Refresh Is a new feature of iOS 7,and possibly one of the main battery killers in older devices. Go to => Settings => General. Kill it for any app that doesn't need it.

Spotlight Search - it is hugely improved in iOS 7, but to work so well it needs to frequently index all the phone's content in the background.
Go to Settings => General=> Spotlight and untick file types you do not want Spotlight to bother with. The more you disable, the fewer resources are wasted by the OS to count your beans.

The Parallax Effect (not available on iPhone 4!) - reminiscent of Android's Live Wallpapers combined with faux 3D-ishness, the Parallax effect is a divisive feature. Whatever you think about it, it does gobble up quite some battery juice and it requires processing power.
You can reduce the effect and thus its power hunger.
Settings > General > Accessibility. Tap the Reduce Motion button, and then toggle on this feature.

Lastly, do make use of the new and convenient Control Centre. Turn off Bluetooth, e.g., when you do not not need it. Reduce screen brightness....


I am not suggesting that these few tricks can make iOS 7 usable on underpowered devices with 2 year old batteries. I am also not suggesting we should have to exchange such tips to make something usable that Apple advertise as iPhone 4 compatible. Parallax and Spotlight, e.g., are 2 of the hyped new improvements. Well, then let me use them...

These are just measures you can take if you want to try everything possible before you downgrade.

I'm not surprised this has happened, the iPhone 4 is well over 3 years old now. It was never designed to be put under the constant stress which iOS7 is causing it. The same thing happened when the iPhone 3G was updated to iOS4, it basically crippled a previously perfectly good device.

People need to remember that the iPhone 4 only has a single core processor, no matter what clever magic Apple do it was never designed to multitask efficiently or effectively, as is the nature of a single core processor.

This doesn't change the fact that the update should work as advertised, but if people engaged their brain before updating ancient devices to new OS' we might have less of these problems.

True.
I'm curious as to the real figures. How many people are REALLY affected?
The Softpedia article quotes a lady with a 2 year old iPhone 4. Chances are, the battery wasn't exactly fresh anymore. Chances are, she used the updated phone a lot more than she usually would - to check new features etc... Chances are, the phone was charging during the upgrade, during the restore and sync and redownload of apps etc... That does make any phone hot to the touch.
But the keyboard lag seems to be a common issue.

Apple should have excluded the iPhone 4 imho.
It's just a stab at Android's perceived fragmentation 'issue' to try and deliver iOS 7 to as many devices as possible.

Having said that: iOS 7 does work flawlessly on my lady's iPad 2 which isn't exactly new, either.

Keyboard lag was the killer on the 3G from iOS3 to iOS4, it ruined the phone (I should know, I owned one as my main device).

Your OH's iPad 2 might be old, but it's a hell of a lot more powerful than an iPhone 4. Remember, the original iPad has similar internals to an iPhone 4, the iPad 2 is more like a 4S (with a better GPU), so I'm not surprised it runs flawlessly.

On the fragmentation note, iOS7 on an iPhone 4 is a very different beast to iOS7 on an iPhone 5S. They might have the same name, but they sure as hell don't have the same feature list ;).

As the iPad2 is pretty much the same as the newer iPad mini I assume Apple spent a bit of extra time on making iOS7 useable on it but not so much on the iPhone4 I find it a bit laggier on my iPad2 I'll turn a few bits off and see if is a bit better.

My iphone 4 runs better than ever on IOS7.

Seems like this is the one thing apple did right this year.

I'm not even looking at the new iphones now that my 4 is running perfect. Finally!

Also: Do you have any Restrictions enabled in Settings => General => Restrictions ??? Turn off restrictions.

'Our' iPad 2, as already said is fine. A bit snappier and battery life seems a tad better too.
But Spotlight search is disabled (my wife never uses it), as are location services. And she only enables radios and background refresh when needed.
Also, she rebooted twice after the upgrade and after the restore, and she let the battery drain to zero... She is like that ;)

Hi,

I do not see the "Reduce Motion" option on my iPhone 4 under Settings > General > Accessibility.

Could it be hidden somewhere else ?

JanSt / MOD  Sep. 23, 2013 at 22:56

It seems iOS 7 Beta had it on the iPhone 4. But it
is not featured now.
I assume you saw the update in the first post regarding the keyboard fix?!

I don't have it on my iPhone 4, either.

Yes, sorry: as already said: Parallax was part of iOS7 for iPhone 4 during the Beta stage, but it isn't actually available now in the final edition.
I've changed the 2nd post accordingly.
Sorry about the mix-up - I have no iPhone 4 at hand.
