iOS 6 vs iOS 7: did performance drop?
With iOS 7 now officially out, we had hordes of iPhone users report their experience with the new OS through pretty much every possible medium. The first revamp of the simplistic OS has definitely rejuvenated iPhone owners' interest in their devices, and that's no surprise – the changes are significant. But, a common question we've seen being asked is whether the new iteration made things better or worse, at least as far as performance is concerned.
Thankfully, we were prepared for this, and we ran a few benchmarks on an iPhone 5 before and after we updated from iOS 6 to iOS 7. And while we've been hearing that the now older iPhones, like the iPhone 4, are struggling with the load of the new OS (not that they were handling iOS 6 all that handsomely in the first place), the situation with our own iPhone 5 was actually kind of uneventful. Across the board, tests provided largely the close to or the same scores, as you're about to see. In fact, the differences were so small that it felt like the two OSes are largely identical in terms of performance.
Here are the benchmarks we tested:
Browsermark is one of our favorite benchmarking tools as far as web browsing goes, because it tries to replicate what you'll usually do once you fire up Safari, providing some pretty relevant feedback as far as real life usages goes. As we hinted above, the differences between the performance under iOS 6 and iOS 7 are close to non-existent here. The scores were averaged over three separate runs.
Another browser benchmark, we once again tested the iPhone running iOS 6 and iOS 7 three times respectively, and then extrapolated the average. Once again, the differences in performance were negligible.
The GPU-intensive GLBenchmark 2.7 should give you a better clue as to what to expect once you turn on the more graphics-intensive applications out there, like games. The short answer is that you shouldn't be any more concerned than you were before the switch.
|Benchmark / OS||iOS 6||iOS 7||Change (%)|
|GLBenchmark 2.7 |
T-Rex HD (onscreen)
|14 fps||13 fps||-7.14|
|GLBenchmark 2.7 |
Egypt HD (onscreen)
|41 fps||37 fps||-9.75|
So, as you can see for yourself, the differences are pretty minimal, almost non-existent between an iPhone 5 running iOS 6 and iOS 7. Seeing as we enjoy iOS 7 more than its predecessor for now, we're definitely happy to see that the seemingly heavier iOS 7 didn't really impact performance, meaning that the experience in that regard will be just as great as with iOS 6, but with the added benefit for a refreshed UI and all the new features.

the reports have nothing to do with benchmarks ...
the problem is with the lag overall ...
5. Droid_X_Doug (Posts: 5859; Member since: 22 Dec 2010)
And Android showed the way to solving lag - add more RAM.... I wonder if the iP6 will see 2Gb of RAM?
11. Chaseism (Posts: 79; Member since: 08 May 2013)
Whoa...Thank god for Android otherwise mankind would have never known that more RAM would reduce lag...
The disparity of power from phone to phone is getting smaller and that has nothing to do with Apple or Google. Technology is getting cheaper and we are finding that last year's phone will stay relevant for much longer than it did in the past (anyone remember trying to upgrade software on a Windows Mobile Phone?) But regardless, we may always see last years phone take a small hit to power for an OS built for the current model. As long as it isn't noticeable, it shouldn't be too much of a problem. Remember the iPhone 3G running iOS 4? Those were some brutal days...
17. Droid_X_Doug (Posts: 5859; Member since: 22 Dec 2010)
Okay - how about Android showed the way to reducing lag on phones by adding more RAM? Amazing how once phones started shipping with 2 Gb of RAM, lag went away?
Now that lag isn't much of an issue with 2 Gb, expect UI bloat (GS IV, anyone?) to occur and we will need more RAM (Note 3, for example) to fix the lag issue again.
Android leads the way though (on phones).

Even with 2gb ram I wouldn't have a non stock android phone. The dumb bloatware skins are ridiculous.
31. techspace (Posts: 693; Member since: 03 Sep 2012)
the iphone 3gs had 256mb ram, the iphone 4 and the 4s had 512mb ram, the iphone 5 has 1gb ram...apple also increase the ram
we all knew everything about ram even before android and ios...
we have also experienced it with the pcs didn't we?
69. Chaseism (Posts: 79; Member since: 08 May 2013)
But you can't judge performance of iOS and Android on hardware alone. Yes, more RAM will help with lag on newer phones. But I doubt people who are buying the iPhone 5S are going to see the kind of lag people may see on the iPhone 4S. Hell, let's say Apple put 2GB of RAM in the iPhone 5S. It wouldn't be unreasonable that two years from now, that phone won't run iOS 9 as well as the current iPhone...but it should do a decent job.
Also, you cannot compare raw hardware power between iOS and Android. PhoneArena has pointed out in the past that iOS sips power in terms of battery and hardware. Android requires a faster processor for it to run smoothly. iOS doesn't. And that's not a knock against Apple...they've created an incredibly efficient OS. RIM doubted that the original iPhone could have such a huge touch screen and yet have a long battery life...and it did.
tl;dr - RAM will help the phone with lag. But as technology progresses, 2GB of RAM will need to turn into 4GB of RAM. And although Android phones usually pack on more RAM and a faster processor, Android needs those to run smoothly. iOS doesn't because it's built to run smoother on less power.

The Note III has 3GB of RAM to handle the new multi-tasking addons. The Note II can run to apps on the sscreen at the same time. It has 2GB of RAM. The Note III can not only run 2 apps, but it can run 2 identical apps and you can open a 3rd app window on top of that.
Also as a fact, I have used Android 4.x on older Android phones that have 1GHz CPU's and 1GB of RAM and they had NO LAG. Speaking specifically of the Galaxy S II.
24. Mxyzptlk (Posts: 3662; Member since: 21 Apr 2012)
iPhone 3G users at that time could've easily updated to the next model. iPhones are future proof for about two iOS updates.
More RAM isn't going to reduce the lag Android still experiences. Optimization and cutting down on the bloat will. But that will never happen because OEMs love slapping their skins onto devices and there's far too much discrepancy in Android for there to ever be true optimization like iOS is for iDevices.
29. PapaSmurf (Posts: 8614; Member since: 14 May 2012)
Or you know, install a ROM and never see lag again. My S3 is running stock 4.2.2 and has never seen any lag. Also, Google has properly optimized hardware with software, which is why the Nexus 4 is still ranks among the best.
And yes, iOS phone are good for two OS updates. The iPhone 4 is almost unusable on iOS 7 since thr update yesterday. It lags more than my computer from 2002 did.
38. techspace (Posts: 693; Member since: 03 Sep 2012)
they should wait for the ios 7 jailbreak
there are many tweaks in cydia (like accelerate) that will make the iphone 4 extremely fast...
43. PapaSmurf (Posts: 8614; Member since: 14 May 2012)
The person who has the iPhone barely knows how to work it. Explaining the mechanics behind jail breaking would be damn near impossible.
53. Mxyzptlk (Posts: 3662; Member since: 21 Apr 2012)
Because rooting is so a walk in the park.
59. SellPhones82 (Posts: 520; Member since: 11 Dec 2008)
Every phone I've had offered "one-click" root options and/or Tool Kits that rooted and installed the customer recovery of your choice with ease! If you can read and follow direction you can root a phone.
61. frydaexiii (Posts: 1236; Member since: 01 Dec 2011)
It is if you have half a brain to follow instructions. Obviously, you don't.
79. XiphiasGladius (Posts: 803; Member since: 21 Aug 2011)
Actually it is a walk in the park. Ever heared of the App Framroot?
83. Sniggly (Posts: 7114; Member since: 05 Dec 2009)
I actually agree with Mxy here. Rooting and installing a custom ROM can be a total pain in the ass, especially when the ROM is in beta and features don't work.
I mean, I'm willing to do it because I find the amount of work and nerdiness involved to be quite fun. HOWEVER, the average customer finds instruction sets that involve more than three steps to be a waste of time.
I spent literally about 8 hours when I rooted for the first time reading instructions and trying to understand, step by step, exactly what I had to do. Even after that, I still managed to soft brick my Atrix in the course of the ROM installation, and it took about another hour before my phone was working with the new software.
I mean, hell, I actually had to use DOS command prompts at one point to finish the job. Ain't nobody got time for that!

So even though millions of ios users have jailbroken before, they just won't for the life of them figure it out next time? Troll.
70. Luuthian (Posts: 217; Member since: 09 Sep 2011)
This exact statement is by far my most hated from the Android fanbase. Why is it the USERS job to make the phone a good experience?
For a smooth operating system it shouldn't be a requirement that the user goes through the trouble of reading what a custom ROM is, reading how to install one, download all the tools, attempt to root the phone (assuming your phone can be rooted), and install the ROM (hope this part goes right or you have to unbrick, if you can even figure out how).
All of that for simple improvements that should have been there to begin with. I dumped my Galaxy Nexus after a year for this exact reason. It isn't fun to constantly scour forums for the latest ROM and Kernal update just so you can keep the smooth scrolling and somewhat better battery life that you already should have had.
Apple has fantastic products with great battery life out of the box. No tinkering required to get the most performance out of your phone. That's how a user experience should be.
85. TechieXP1969 (Posts: 292; Member since: 25 Sep 2013)
False. The lag many see on Android phones is not the Android OS. Its the TouchWiz layer that runs on top of it. Phones with what they call Vanilla Android which is stock Android with no skin, doesn't have the same problem.
Also I have a Galaxy Note II, it has NO lag even with 2 apps on the screen at the same time. Why does an iPad and iPhone have lag with iOS 7 yet only one app is on the screen at any one time?
51. Tsoliades (Posts: 213; Member since: 22 Dec 2012)
My friend's iPhone 4S lags like crazy now. I wasn't very impressed.
8. rihel_95 (Posts: 220; Member since: 21 Mar 2012)
it clearly shows iOS6 won all benchmarking test than iOS7, though by a little margin. In case pf android, old Nexus7 showed better benchmarking result after updating to 4.3!
21. PapaSmurf (Posts: 8614; Member since: 14 May 2012)
Disagree. My Nexus 7 got 2x faster after the 4.3 update.
23. Droid_X_Doug (Posts: 5859; Member since: 22 Dec 2010)
But you are comparing Apples to Androids. Literally. Apple is a hardware company. Android (Google) is not.
26. PapaSmurf (Posts: 8614; Member since: 14 May 2012)
Re-read your comment again. Nexus 7 did get faster after the 4.3 update.
My cousin's iPhone 5 saw a boost in speed but my other cousin's 4S is lagging.
27. Mxyzptlk (Posts: 3662; Member since: 21 Apr 2012)
I can't wait to hold the best in my hands. Apple can just shut up and take my damn money.
63. frydaexiii (Posts: 1236; Member since: 01 Dec 2011)
You are so lucky PA has to settle for idiots like you for their Apple fanbase that they had to remove the thumbs down button.
77. -box- (Posts: 3820; Member since: 04 Jan 2012)
I thought you had an ip5. What's the incentive to get the newer model?
Also, "best" would mean apple wouldn't be getting your money ;)
28. Rocksteady (unregistered)
Yeah Rihel_95, totally agree, updates are supposed to bring performance improvements, not reduce it.
47. Penywyz (banned) (Posts: 255; Member since: 13 Aug 2013)
You can just download the iOS you don't have to get in line to do it...
3. _Bone_ (Posts: 2135; Member since: 29 Oct 2012)
Gotta say I'm more impressed with the 5S by the day. Judging it by it's cover and hell nawww, it's the same old again, but actually both SW improved (hate the colorful looks though) and performance is just incredible, Apple really outdid themselves here. And the fingerprint scanner... just works, easy unlock in a flash. The reason I'm staying the Nexus user I am is the small screen, I just don't wanna go under 5" anymore (not that I'm even there with the 4.65", but it's a matter of weeks).
6. boosook (Posts: 1029; Member since: 19 Nov 2012)
And after the fragmentation, as the number of feature increases... here come the lags! :)
(just joking... the difference is small)

Look at ARS to see how the iphone4 is slower on iOS7 arstechnica.com/apple/2013/09/new-lease-on-life-or-death-sentence-ios-7-on-the-iphone-4/
34. PapaSmurf (Posts: 8614; Member since: 14 May 2012)
It took 12 seconds to open the settings yesterday on the iPhone 4. Imagine how long it took to turn on WiFi.
49. LordDavon (Posts: 107; Member since: 19 Sep 2011)
My iPad 3rd Gen 64GB unit slowed down drastically right after the update. It took forever to do anything. I figured that it was probably rebuilding indices, caches, etc. So, I left it alone for a while. After about 20 minutes, it was usable again. I did find things to still be a little less responsive, but this is just the first release, and they can still optimize things.

hmmm even on the Iphone 4 it still doesn't show much of a change but seems like it causing it to load slower than normal. but slight lag shouldn't be that bad for a phone
10. TechBizJP08 (Posts: 495; Member since: 25 Mar 2013)
i saw some lag on iP4S, but its minimal. I just hope some iPhone users like my friend accepts that. And be blinded and say no there is not. :)
Anyway, Cheers for iOS 7..
12. jeff_1 (Posts: 105; Member since: 30 Aug 2013)
see haven't i said don't waste your time guys upgrading..
nothing really change except adding +1 on the name to make it 7.
im pretty sure the apple's innovation team is under pressured right now by the board.
anyways as per report more than 70% of iphone and ipad users are now on ios7..not surprising.. in the first place who are these users? what these users think, whats there i.q, know there status, you will get the answer.
13. BigBoss10 (Posts: 232; Member since: 31 Aug 2012)
Battery drains faster... stay on IOS6!!!
14. dexter_jdr (Posts: 1145; Member since: 28 Jun 2012)
oh really pa? how about giving benchmark to iphone 4s ios7
39. Googler (Posts: 813; Member since: 10 Jun 2013)
I'd like to see that too. For people with that or the 4, upgrading could be damaging in some ways, a heads up would help.

My iPad 4 seems slower to get to any site which drives me crazy.
18. Droid_X_Doug (Posts: 5859; Member since: 22 Dec 2010)
That was part of Apple's plan. Now, you will be ready to move to the new iPad (5?) when it ships. Like sheep to being sheared.
Welcome to life in Apple-land.
22. papss (unregistered)
I assure you I'm no apple guy but the iPad is a great piece of hardware.. Shouldn't be laggy or delayed. If it doesn't get fixed I may stop using it all together.. I use my pro more but the iPad was great for light things at home.
25. Droid_X_Doug (Posts: 5859; Member since: 22 Dec 2010)
I wasn't saying you were an apple guy. Just welcoming you to Apple-land.

True.. Freaking apple.. Good thing I didn't update my wife's iPhone 4 eh?
57. dexter_jdr (Posts: 1145; Member since: 28 Jun 2012)
they all now make evil laughs on ios7 global release
73. Droid_X_Doug (Posts: 5859; Member since: 22 Dec 2010)
"Good thing I didn't update my wife's iPhone 4 eh?"
Smartest move you have made this week. If you had upgraded your wife's iPhone 4, you would have been on the hook for a 5S for all the misery you would have gotten for the effort.
68. good2great (Posts: 1039; Member since: 22 Feb 2012)
this seems crazy... i have the ipad 2 16gb and it works perfectly.
it did take about 30 mins to install iOS 7 but i promise you have no single problem...
not sure why you are having a bad experience.
20. PapaSmurf (Posts: 8614; Member since: 14 May 2012)
The iPhone 4 in my house was slow to begin with, and even slower after iOS 7. Thanks Apple.
32. power_x (Posts: 236; Member since: 28 Aug 2013)
But keep in mind that iPhone 4 is three years old and only runs a single core
36. PapaSmurf (Posts: 8614; Member since: 14 May 2012)
If the software makes the user experience worse, it shouldn't have been pushed in the first place. iPhone barely has 100 photos and no music, and it takes a few seconds longer to load apps or the phone simply freezes for 15 seconds.
I know it's running on a A4 chip, but damn I'm a little disappointed.
41. Googler (Posts: 813; Member since: 10 Jun 2013)
And the version of iOS7 they received was stripped down as well, this shouldn't be happening.
45. terabyteRouser (Posts: 434; Member since: 18 Oct 2011)
lol your complaints are warrentless. iphone 4? seriously
