Does your iPhone actually get SLOWER over time?

Thanks to Sharge for sponsoring! Check out Shargeek 170: bit.ly/3TvJ1rt
Does your iPhone get slower as time goes on? Maybe in the past this was expected, but now it's a subject of much debate. Can age alone cause an iPhone to become slower? As the battery degrades will performance get worse? Do iOS updates make iPhone slower? Today we're going to examine all of these questions to find out if your iPhone is being slowed!

Yeah, the Apple Store in Sacramento near me just has groups of criminals in the parking lot robbing anyone coming out of apple.. so I can’t even get a legit battery replacement. Ends up being safer to just buy a new one 😮 and create a bigger problem. It’s pretty lame actually. I wish there was a way the user could replace the battery themself 😢 Edit: I should add, I don’t like what the EU and now America are doing to Apple for not playing ball when it comes to privacy, it’s pathetic and wrong.

This Note8 is a beast as well, it’s moving along at the same pace since the screen protector was pulled. Battery is roughly same and with normal use goes from morning to evening before it’s around 15-20% and will totally charge to full in half hour or less. Due to the note7 the Note8 is known for having a smaller battery than the competition at the time. Ram usage is exactly the same as when it was new give or take half a gig but it’s still showing the same amount of free ram available. I never had anything over the screen like a glass protector or anything and it’s on it’s second Incipo Back cover protector, same quality as an Otter box. Both sides of glass still not broken.

Apple already confessed that if your battery isn't acting correctly, iOS slows down your processor. That of course caused stuttering and slow performance.

No, my previous device, the 7 Plus, had a battery of 96 and it became slow. It was sold in 21 months 5. An iPhone 12 came to me as a gift. Perhaps if it had not arrived, I would have delayed the upgrade a little, but the device slows down because its processor is slow, and the company may slow it down, and consumption also plays a role.

[@mattb9664]

It's the security and the new features that make the phone feel slower. New and extra unplanned software items running in the background on an older phone cause it to feel like a slower phone over time. And with the battery aging degraded capacity over time- the phone experiences voltage dips when the processor loads while it's working hard- to prevent the voltage from collapsing and the phone shutting off instantly, they can downclock the processor to prevent voltage dips. (When I say downclocking, that can also assigning the work to the efficiency cores rather than the performance cores. -this could explain why there are variances in performance on the used-phone in the synthetic benchmarks.) The experiment to have also include would have been to fully upgrade the iOS on the brand new phone, then repeat the benchmarks. This could have made this comparison pretty definitive because nobody on KZbin or tech news sites have done it yet.

But usually iOS doesn’t have much bigger updates right? I mean, I don’t see much change in every iOS, more if we compare 16 to 17

[@thundertwonk2250]

@@tarugo06you’re thinking too surface level

[@user-ue9sz5rj9w]

@@tarugo06 There is a difference in terms of security updates and compatibility with new programs. Any difference, if it is trivial, burdens a device

[@mlykke]

You should have upgraded the new phone to the same iOS version. That would eliminate what is the biggest difference in performance. The new phone wasn't really faster - In some tests it was and in others it was slower. But the difference is so small that the reason for the difference is most likely the major difference in iOS versions and minute differences in how fast you click on one compared to the other. You could take 5 brand new iPhone 15 Pro and run the same benchmark - you would get 5 different results all differing within a few percent of each other. Short version: No, the iPhone does not slow down. Differences in performance is minute and is explained by newer iOS versions having more features and usually requiring a bit more CPU and that every single CPU has slight variations in performance.

[@selenix]

You should’ve tested something like iPad 2018, it’s literally unusable now on iPadOS 17. It was very fast on IOS 12, but now it drops to 30 fps even in Hill Climb Racing and crashes frequently. Benchmark score is the same, but real life usage performance drastically changed.

[@Itsraminstech]

woah nice this was such a nice video!

[@randomscience4k]

Actually since iPhone 5S onwards due to improved performance they aren't unusable like the 4S or 4 on the latest iOS versions. Since XR series on wards they are still very good like what you found in the video, very usable. Atleast this is what I noticed.

[@Eddy_E.]

Even the 5 is still useable on the latest software it runs, the 4s, iPad 2, iPad mini 1 where the last devices with those issues…

[@user-ue9sz5rj9w]

@@Eddy_E. The iPad 2, even on the latest version, had great performance, but most of it was used for games without the Internet, and this is what maintained its performance.

[@tonep3168]

I think RAM and battery condition are most likely culprits for most people on later upgrades of iOS.

[@nicholasdavies168]

What about updating the old one to iOS 17 and trying these tests again?

[@AndreasC81]

This is how software updates work. Some things gets faster and some things become slower. It’s how software development works. Overall updated software makes things better and more optimized but some things may take a hit. Then, you have to keep in mind that the hardware is old and with new software with more and heavier functionality, it can become less responsive or slower cause the hardware can’t keep up. It’s quite impressive that the lastest iOS work as well as it does on several generations old hardware.

[@HelloSwiftful]

They don't optimze new iOS versions for older screens anymore, so everything feels cramped. I think that is the noticable difference.

[@bluezenither7043]

inaccurate, use the same colour and storage for +5% performance

[@vedantwkr]

This is great video for peoples looking to buy old second hand iPhones

[@vita007]

my xs is weird, anything that has to do with the camera lags. not the camera itself but for example in instagram when you swipe to the camera section it just lags for few seconds. and when you close the camera the phone will lag again for a moment. Ive reset it 2 times but well i guess its time for a new one

[@maddaxsaya.3477]

I have a 13 pro max (ik not very old yet) but i did start to feel like my phone was getting slow and the battery was draining too quick. it used to last about two days when it was new, then it started to only last about a day. Later on, I had my battery replaced since my phone was damaged and it would be good to replace the battery too. I got my phone back and it felt like a brand new phone again, lasts about two days on one charge and runs smooth. Just take care of your battery, don’t stress out your phone, and try not to max out your storage!!

[@duanebrankley8984]

what would happen if you Update the New iPhone 10 to the most current iOS? & run all the test again.

[@LondonCityEvents]

Great video what about updating the both phones to iOS 17 and then rerunning the test?

[@pennymikk]

Upgraded my XS last September! Broken screen, 72% battery & full memory but still an amazing device!!!!!

[@heobay807]

I'm currently using an iPhone XS black myself and i gotta say it's having issues with the heat, if i ever tried to do anything without sitting in a room with AC on or using the phone cooler it just gets too hot and decrease the screen brightness automatically, and it also runs out of battery faster too

[@Kyle-9570]

Great video, would think that a lot of difference would be due to the battery health. What I’ve been wondering is if apple have been slowing down the Intel Macs?

[@martinjjnoagenda5536]

My iPad Air 2nd gen now got stuck in iPadOS 15.8.2. I clearly notice it sometimes stutters with everything I try or even completely freezes. Never had that before. The battery is fine as it's basically connected to power all it's life. I now have to reboot it frequently to get it going again. I don't think it's the hardware as nothing changed, but more likely updates on various apps. They probably become more complicated and harder to process. More memory required? Looking for functionality that isn't there? Maybe Apple is doing stuff in the background we usually don't notice on faster new devices? Who will tell? Just like with the typical desktop OS it's usually software related. A fresh install can do miracles.

[@ColinsCity]

My iPhone X just randomly stopped responding to touch no matter how many hard resets and factory resets and 2 DFUs I did, I replaced it with an iPhone XS Max and i really hope they give it one more cycle of iOS support because they are great phones at a very good price on eBay

[@LeomM-ey2dq]

Maybe it would be interesting to compare both new phones, one on stock iOS et one on the latest version of iOS ?

[@andersonamato]

Amazing analysis!!!

[@centurioneyt9235]

I Always wanted a video like this😂

[@gentle285]

I would love to see more app speed tests.

[@SamuelSimeon]

Good job with the video. I think the batteries are where the devices differ. Maybe if the used phone had a battery replacement, it would have run on full performance mode as compared to when it has less that 90% battery? maybe that was a factor?

[@HannesHerrmann-tw6om]

how does the brand new one compare to the old one with the same ios installed?

[@EverettCDavis]

I did a similar test years ago with the iPhone 5, and I can tell you that there was definitely a great deal of slowdown when upgrading to iOS 9, and iOS 10 was practically unusable. It ran so well on iOS 8 though.

[@CrunchyTire]

Im very impressed how you managed to handle it without it crumbling to dust. A true relic of our past

[@Shokamoka]

My Galaxy Not 10+ at 78% battery capacity still chilling. Still does the things I used to always do in the past years well.

[@volvofreak86]

There are some differences sure but that could be anything, maybe not the OS itself but maybe given the older phone has more apps running in the background and so on, i am not sure you need to upgrade to the latest one after seeing this

[@actuwow]

Very good tests.

[@AlexGFrank]

so, as a person who has a couple of iphones in the collection and used them as dailies for a while, i haven't really noticed any CPU slowdown, BUT the phones get considerably hotter with each new update and become way worse at multitasking, bc the new OS versions take up more RAM. For example, even on ios 15.7 my iphone x struggles to keep some apps (KZbin, Telegram, Discord, etc.) in the same state i left them even when switching out for a minute or two, and that's extremely frustrating

[@adityadubey177]

That phone have A12bionic and that chip held up good cause it was ahead of it time when compared to androids and a13 and a14 were minor improvements

I have an iphone 7 since launch and it's falling apart... Losing network during calls, wifi connectivity issues from time to time, gets really hot while using certain apps like the camera, instagram e.t.c... Quite slow in general and it's due for an upgrade.

How did the phone not force you to update to latest IOS before set up? Every single iPhone that I’ve set up for someone has always required the latest version of IOS to be downloaded and installed before setup has finished
