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.

Closing a web page in Safari is hilariously bad on the iPad Air. You see like a little white rectangle that suspends there for 2 seconds before the favourites pages finally flies into view. This stuff is more janky then HTC sense on the Sensation. Lol

My iPod touch 5th gen, which has hardware comparable to that of the 4 year-old iPhone 4S works PERFECTLY with iOS 9.

I wouldn't try the beta on my main device, the program is really tricky to get out of. I wound up having to take my Air to Apple, due to a recognition glitch. Please be careful guys, if you decide to enroll in the beta program. They had to extract the software, do a fresh 8.4 install, then upgrade from there. Works great now.

I'm with 5s and ios 9 : works perfectly, and even removed the worst bug ever - two second delay in response to an incoming call. :)

See, I have to wonder, iOS needs to work on very specific products, and that's about it, Android needs to work on a broad range of products. Yet when Android has bugs, its inexcusable and such. yet iOS has bugs, and it is excusable? really? this whole brand loyalty thing confuses me.

I hope 9.1 can fix the framedrops when accessing Spotlight Search and GAWD, bring the back the old stills. The new ones are too f*cking feminine.

I sense some societal pressure and self-loathing here. Can you tell me the root of this? Maybe your dad beat you for being to feminine when you were a kid?

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

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.

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

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.

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.

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.
