Does iOS 7 Slow Down an iPhone 4?

Yes, everything is slower, uses more battery power etc. etc. etc.. The list goes on and on... In all honesty, I wish that I had never updated to ios7 on my iphone 4.

If you have an iphone 4, I would not reccomend updating to ios7 until apple pushes a fix.

Once things *normalize* i will edit this post and give it my thumbs up. Up till now, It's been a frustrating experience.

I really do hope that Apple follows through.

We are all agreed ios7 is a disaster on the iphone 4S but sadly I doubt Apple cares one jot.

Hi there ! At first, I installed iOS 7 on my iPhone 4 over the air. It was really slow. But after several days, I restored my phone using iTunes, set it up like a new phone and filled up manually all my content back to the phone. Now it works like a charm, better than iOS 6 did before.

The only problem with that is I have Google Authenticator app for 2 factor authentication for my Gmail accounts and other like Dropbox. If I reset the phone completely, I will have to do that all over again and that is a painful task. Not to mention setting up the email accounts on the phone again (takes an extra step with 2 factor auth).

I honestly think I will just move to Google Nexus just because of this pain. I have been an Apple customer forthe sheer reason that they are user friendly. If I have to reformat my stuff like one does with Micrsoft Windows, why would I want to stay with Apple? They could have easily tested this feature of upgrading on iPhone 4 before releasing ios7.

Realy?? i will restore my phone tonite..

I agree! I have postponed upgrading my iPhone 4S. I tried to get help from Apple to see if they would at least acknowledge an issue, but they told me factory reset which ended up being a waste of time. The next solution was to upgrade my phone. REALLY?!?!?! So, it is doubtful that I will upgrade to a 5S anytime soon nor will I upgrade my iPad. I may get an original iPod so I can continue to use my iTunes, but then dump the iPhone and Ipad for a different device. This is so sad because I had loved my iPhone, but now it is just an overpriced mediorce product. IOS 7 ruined my Apple Experience. I have sent numerous feedbacks to Apple, but they don't hear anyting, but they want to hear. SAD

Please don't upgrade to iOS7 if you have an iPhone 4. Really bad experience. Not sure how to get back to iOS 6. Can't understand why Apple would have allowed this to happen.

this one works. just tried it.

Finaly restored my phone. I did it step by step, but it didn' work- my phone is even slower.

yes, this works great, I'm using 4s with iOS 7.0.3

after turn Increase Contrast to On, the transition animation gives no lag anymore

thanks for sharing 🙂

Nice observations there !

Thank you dilbert41 ! Your suggestions of turning off documents from icloud helped speed up the phone considerably.

for me it ddn't work, but I turned on the "Reduce Movement" it did.

I have an iphone 4 16 gb , and there is not much of a change in disk space for me ! But there is a significant change in the way things run ! Everything except the camera is slower by 1,5 seconds average !! And you have to do a lot of settings alchemys to change that a little ! And some 3d games that used to play super smoothly with iOS 6 now are on slow motion and it's super annoying ! (Example some endless run games like monsters univ. Stuck all the time and. Any be played ! ) the typing and the scrolling are slower too ! Only after following some advice on what to turn off on settings I managed to make the 3d games play well ! They really did improve ! But the scrolling and the calls even are slower ! Ex. I click to call a contact and the call screen appears after 2 seconds I can't even close the call fast if I regret it !!!! So WAIT AND USE IOS 6 !!! If ps : I have 40% ram free when doing nothing and my friend with iOS 6 has 63 % I also must say that I have more installed apps than her but still ... The desabling of Iclouds.. backround stuff.. ects. helped a little but not that much!

it slows it down to a complete an utterly unbareable level. I truly regret upgrading. Even after i restored my iphone 4 to factory settings, it was sluggish at first, but still useable. However after a few days of normal use it's back again to being useless. I am currently in the process of buying a used iphone with iOS6 on it so i can once again have a phone that doesnt make me lose my mind. This same thing happened a few years ago when i had an iPhone 3G. I'm really disappointed in apple for doing this. I wish they'd at least permit us to downgrade the software.
