Video compares iOS 9.1 beta with iOS 9.0 on the Apple iPhone 4s and Apple iPhone 5

Video compares iOS 9.1 beta with iOS 9.0 on the Apple iPhone 4s and Apple iPhone 5
Some of those still using the Apple iPhone 4s and Apple iPhone 5 are complaining about how sluggish iOS 9 is on their handset. Considering that the iPhone 4s has 512MB of RAM and a dual-core 800MHz CPU compared to the 2GB of RAM and dual-core 1.8GHz CPU on the Apple iPhone 6s, you might not expect iOS 9 to be running smoothly at all on the older phones.

As it turns out, Apple is currently pushing out the iOS 9.1 beta to those testing the new build. So of course, those with the iPhone 4s and iPhone 5 would want to know whether Apple was able to improve the performance for those rockin' the older models. Many have reported a major improvement for those two greybeards after installing the beta. To see if this is really so, the iPhone 4s and the iPhone 5 were put through the paces while running both iOS 9 and the beta version of iOS 9.1. The test was recorded on video

Two iPhone 4s units were tested side-by-side. The one on the left was running iOS 9 while the one on the right had the iOS 9.1 beta installed. The pair of iPhone 5 models also had the one with iOS 9 on the left and the unit running the iOS 9.1 beta on the right. The bottom line? The animation on the pull-down notification shade was a bit faster on iOS 9.1. Other animation was smoother on the newer build of iOS.

Overall though, it really was a toss-up which iOS build was faster on the iPhone 4s, while iOS 9.1 was faster on the iPhone 5 by a slim majority. Regardless, the difference in almost every case was a fraction of a second. Looking at the video, it really doesn't seem that there is much of a change in performance between iOS 9 and the iOS 9.1 beta on those two specific iPhone models.

on this day and age, I can never understand why would someone continue using their 4s or buy a 4s.. I'd really rather go for the 5 or 5s..

Some might using it for basic needs like telephony, messaging, social media, etc... I think it works pretty well for that purpose, i notice lags and slow down when access facebook or any social media on my friends 4S & 5. Well if they can compromised that issue i think it's fine.

Most useless Update ever !! nothing is there to be happy , only powersaver, that powersaver not even close to samsung powersaving, those updates are to make ios fans mentally happy , nothing else. iOS9 = Android ICS 4.0 4 iOS updates = 1 Android update always, Even 128 ram phone can run poor iOS 9

Samsung has devices with 1GB of ram that have multi window or splits Creek capabilities, why can't Apple? I have an original Mini. The specs are sufficient for splits reen, yet it doesn't have it. I rather they don't update it if it isn't giving me any benefits. Just upgrading to share the same version number so they can brag about adoption rates is stupid. Ifans just don't get it. I don't care if Android take forever or never comes, a 3 year old Android can still outdo the latest iPhone on some level. IOS9 such and I refuse to buy a newer device just to have it. These one at a time upgrade features just aren't worth the money.

Not everyone is rich to s shelf out money every year getting new iPhone, the word "it's just work" is exactly that, most people will still using theirs as long as it's still working.

I still have my 4S and use it for my second instagram and Facebook accounts, Sure it has slowed down, but it works just as well as my iPhone 6 or my brothers Note 5.

I use 4S as my daily driver and I don't see any reason too upgrade, texting, calling, FB and music work very well and I don't really use phone for any other things. Maybe I could use bigger screen for reading some articles or tabs for guitar, but it isn't necessary. When 6S prices drop under reasonable level I'll get it but I;m good for now.

Updates fix security vulnerabilities, at least most updates that companies push out do. Apple has been rather bad at patching security issues lately, in both IOS and OSX. They are in fact, the most insecure operating systems on the market.

iPad Mini 2 (same A7) its pretty good except spotlight search and the app switcher always lag/frame drops Might because of the resolution difference Hopefully its fixed in iOS 9.1 iOS 8.1 fixed iOS 8's performance for me

Yeah Probably The Difference In Res, Cause I Basically Have No Lag And Frame Rate Drops Aren't Noticeable. Best Of Luck With 9.1 M8. But There Is A Problem With Sending Pictures Takes Like 10min To Be Sent.

I have 9.1 on my 6plus and its worst than 9.0. Some of my picture mms don't go out and if they do it takes at least 5 minutes to send, Google Now shuts down, phone apps lags horribly, and other issues. This is the worst iOS build. Apple needs to fix 9.0,9.1 asap. What a mess this is.

Pretty pointless test without similar phones running older iOS versions, as well as an iPhone 6 running iOS9...

My iphone 5 is a little bit slower on Ios 9 compared to Ios8. Also it is sad that adblocking is not available, browsing Phonearena with a hideous list of ads keep me away from using the Iphone.

Do you notice any battery improvement? My friends iPhone battery life are somewhat poor they'll need to charge theirs twice a day. I would suggest them to install iOS 9 if it help, but of course slowing the device isn't good to hear - it's like solving a problem while creating others.

I tested the battery life by using it for a day. Seems pretty much the same. Power saving mode is not that effective really. My usage revolves around heavy web surfing, playing games for about 30 minutes and 15 mins of YouTube watching and the rest is idle with mobile data always on. It died on me at 6pm. IPhone has weak battery life so I don't use it anymore. Charge twice a day for an IPhone is pretty a given if you ask me.

Adblocking is available in iOS 9, look for dedicated apps in App Store.
