Does Android use more memory than iOS? - Gary explains

[@keco185]

I'm not subscribed to this channel so when I clicked on this video I was expecting a poor explanation that basically ended at the 9 minute mark in this video. Super surprised at how in depth this went and how bi-partisan the video was considering the channel name. I suppose the name doesn't summarize the views of the channel here.

[@mwood65]

keco185 they have to make a long video to make money from KZbin. A lot of it is filler.

[@heynando]

careful there. he's right in some aspects, but wrong in others. There are contradictions within his own statements. For example he says that the amount of RAM needed by Android app is certainly not double three seconds after showing a graph stating the KZbin app consumes literally more than the double. I've watch the whole thing and honestly a bunch of red flags were raised throughout the whole video. I say be cautious.

[@AlSnoopsReid]

Yes ,Android did indeed use double the ram, but for one app only. In other situations Apple used more and as Gary explained, after averaging it all out, the Android system used approx 6% more ram overall. You need to stop cherry picking information to suit your argument and see the whole picture. Please feel free to reply in your own video explaining where and why Gary is wrong. Oh, you're NOT actually a software engineer!? Oops!

[@jasonlisonbee]

Android uses compressed swap files in RAM. Phone manufacturers may choose to have that enabled or disabled regardless the RAM capacity. I have 1GB in one 2 in another. ZSWAP enabled on both by default. I. wish xz compression was used though. Additional space savings outweigh speed disadvantages. I used it on an athlon xp with 2GB RAM. xz beat the default handily in overall performance and stability.

[@xpmyt341]

That that the first part is rubbish??

[@RackaApps]

@@xpmyt341 no. Some of us already know how android ram management works

[@ckingpro]

Apple also uses compressed memory since iOS 7 so it is probably compression. Also, for iOS, it can ask apps to purge cache, etc so the app is still running but it may have to do computation again, etc. Another thing iOS can do is it can purge memory-mapped files. Any file that is copied to RAM but not changed in RAM can be evicted. If an app needs it again that part of the file is immediately loaded from flash. Keep in mind that flash memory in iOS is usually faster than flash in Android as well, so that could also make a difference. Also, part of the reason apps use less memory is that the Java runtime may use more memory though ART (Android Runtime) replaced Delvik. Another thing is that graphics in iOS can be smaller due to the limited set of iPhones (so they can be exact sizes needed). Another thing I can think of is that if an app uses web resources then webkit is used (which is more efficient than Blink in low-memory scenarios (as can be seen in Chrome vs Safari on the Desktop)).

[@stephensnell5707]

That is false Android is just as efficient as ios will be

[@ckingpro]

@@stephensnell5707 Ironically, what you posted is false. Benchmarks of memory usage of apps have shown over and over. In addition, I forgot to mention that Android’s garbage collection also leads to higher memory usage (and unexpected pauses which can be mitigated) vs Automatic Reference Counting (ARC). Android does have its own equivalent of compressed memory and purging memory caches, however

[@stephensnell5707]

@@ckingpro I know what I am on about you fathead as I happen to use an Android Smartphone and I find Android very efficient at handling the apps I use and the memory never runs out as I close apps when I am done with them,I do that to stop them running while my phone is locked(in other words to stop background usage) So stop calling me a liar and piss off

I believe its due to iOS dedicated to 1 model which is iPhone. So software optimization is pretty simple and easy to maintain.

There are some great OEM who optimize their custom UI to perform well. :)

[@bobbrown8661]

I once enabled the swap file on iOS 3 for the original iPad which only had 256mb ram at the time via jail break. Was able to use maybe 30 tabs in safari without reloading (not heavy pages mind you). Only slow down was the initial freezing while the pagefile was being created. Turned it off after a short while though due to concerns on the longevity of the flash storage. The nvme being used in the iPhones today is ridiculously fast, something I wish Android manufacturers would adopt.

[@arjunkharbanda]

RAM is also a selling point in Android

[@GarySims]

Very true.

[@davejohncole]

RAM is essential for the way Android works. Your Android device has the capabilties defined by the collection of apps you install. Those apps can and do run in the background to dynamically extend the native abilties of Android. iOS cannot do this to anything like the same degree.

[@fernando18455]

Dave Cole Jailbreaking is the solution

[@karlkingofducks5764]

You are right but RAM is a marketing tool, I couldn't ever imagine needing 6GB of ram on my phone at the minute. I had 3 GB on a phone running MIUI (which uses a fair bit of ram just for the UI) and never once cut into the 3rd GB, I even had 3 games running at one point. The problem is your average user either doesn't know what RAM is or thinks it makes their device faster simply by having more which simply is not the case in most circumstances, but RAM is cheap for manufactures to add more and use it as an extra selling point, much like what we've seen in the low and mid end GPU market.

[@davejohncole]

Duncan Pringle the way Android divides up your RAM means that each app only gets a fraction of the available RAM so that you get multitasking without needing to swap (there is not swap on an Android phone - unless you root it and configure it). A galaxy S2 with 1G of RAM would kill an app that tried to use more than 64M. A nexus 5 with 2G would only allow 192M for an app. This limit is relaxed for apps published as requiring "large heap". iOS does not limit the memory used by apps because it actively suspends and kills background apps. This makes large RAM devices not as important on iOS.

[@kunalnarang1912]

Oh, come on Gary... Apple solved it with software, and Android just added more RAM to conceal the underlying issue. I hate Apple for having crappy overpriced products with closed software. I've always liked Android for its openness, but while having more RAM is a great thing, that doesn't fix the underlying issue. I find it hard to believe that Android developers haven't yet figured out how to tackle this issue from a software standpoint. I would love it if my 4GB RAM Android device could also compress (or whatever iOS does) background apps. That would give me the best of both worlds. Apple on the other hand can offer the best of both worlds to their consumers, but they won't do it.

[@gurdeepmundi6440]

i think it is because android doesn't have so fast processors as the iphones have so compression and decompression on android could slow the system down.

I have several Android tablets and their performance with background processes is quite different. Some lag more than others so some are not managing things in the background as well. If you have an older phone or tablet or even a new one that is lagging try some of the following. 1} Turn automatic update off for the whole Google Play Store. Things updating in the background take up memory and slow your device down. 2} Go into settings and sync all your accounts especially your Google account. 3} Have preinstalled Google apps you never use? Disable them. (Don't disable Google Play Services.) 4) Go to Settings -> Storage. Press the cache Icon. Say yes if invited to clear cache. Wait a few minutes. 5) If you still are having trouble do a restart.

[@Razor2048]

One reason for the belief of RAM issues on android is many non-stock builds from some devices have poorly made RAM management. For example, some of the older Samsung smartphones (assuming you didn't use cyanogenmod), they would start unloading apps from memory even though there was around 500+MB of available RAM. It is still an issue today where some smartphones will have 4GB of RAM, but they will be unloading apps when there is 1GB of free memory. With a rooted device, you can often tweak when it begins purging things from RAM, and often with 4GB of RAM, you can often nearly double the number of apps that can stay in RAM. Another issue is that android has issues with freeing up RAM when you close everything. launch 20 apps and then close all of them and the available RAM will not reach the levels of a fresh boot. From companies like asus and and other brands, you can end up with 2GB of available RAM at startup, but after opening a number of apps, and then closing them all, you end up with less than 1GB of available RAM, then if you attempt to repeat a multi task test by seeing how many apps you can launch before it unloads something, all of a sudden you can only load a small number of apps. This is an area that Apple has done well in. While you can't launch as many apps before unloading starts, the amount you can load is consistent, where as on some devices you can load 15 apps after a fresh boot and have them all work and not be unloaded, but close them all, and then only to be able to load 8 or 9 when you redo the test. In those cases, all you can really see is the system all of a sudden eating up more RAM, leaving less for apps and cached data. Even with android 8, it still has this issue. Android 8 uses more RAM than the desktop version of windows 10. (an uncluttered startup with cortana and other bloat disabled, windows 10 on a system with 8-16GB of RAM, will consistently use around 800MB of RAM, while on a device with 4GB of RAM, you can see android using 1.6-2GB of RAM depending on how far away from stock the phone maker goes. Why is it that windows 10 is far more functional but manages to use less RAM than android?

[@syarifairlangga4608]

Its end of 2019. My 6gb android only have 1,5gb free ram

[@pilotavery]

Yes but that's okay. Any ram that's not being used is wasted. Available is different than free ram. Available ram means that the phone is ready to dump a bunch of ram to free it up but it decided to just keep the ram used with some other apps so that if you open it it's faster, if you open a new app it immediately kills it.

[@Gaxriel]

I have on Android free 1-1,7GB RAM with total of 3GB of RAM Sorry for my English

[@justins7796]

Try SD Maid from the Playstore, it works well to free up some memory. Also in your phone's settings, enable Developer Options and scroll to the bottom to Background Apps - disable any that you never need in the background. If you're experiencing any lag or stutter, delete the cache partition. -(requires safe mode reboot) Lastly, for a 'feel' effect, try removing animations to see if you like it.

the internal memory is Random Access Memmory too, you wanted to say that you are going to talk about operating memory. every memory in PC or mobile are random access, it is big mistification that we call operating memory RAM and not the other. example of non random access memory is FIFO and LIFO (first in first out, last in first out)

[@shadowknight7976]

Guess what Gary, I appreciate the way you managed to explain all this in a very mush so fascinating and entertaining way that leads one to clearly understand what you said, thank you.I knew how this all worked on the PC/desktop side but wasn't sure how they made it work on the mobile computing side (cell phones) since they are so much smaller in storage size for both RAM and ROM as compared to desktops or laptops.

Which phone do you have

[@CypressFrankenfeld]

Hey Gary, could you discuss how Automatic Reference Counting in iOS vs Garbage Collection in Android effects memory usage? I was under the impression that the android runtime garbage collector was at fault for slow performance in high memory pressure situations.

[@Slash310579]

iOS shows a screenshot of the last instance it was on and in the meantime i reloads the necessary data aslong as there is still enough available RAM. So sometimes it takes 1-2 seconds till you can continue using an App on iOS or if it has to reload the entire app even tho you see the screenshot right away and the user thinks the app in still in memory. On Android on the other hand, you see the actual running app and can continue using it relatively right away, as long it still is kept in memory.

@Ramification umm ok?? What does that mean does that mean android is bad??

[@B6_FouR_7]

I used to have a android phone before with a 4gb RAM. But it was stollen to me on a train. It can multitask with ease, no problem with that. Then I decided to buy a temporary phone which is cheap for that time and it's Iphone5s. I was amazed ! This is the firsr IOS phone that I got and it has a 1gb of RAM but it can multitask without lag or any problem. Smooth AF, apple is doing a good job with their devices.

[@christiancuevas6086]

This is in-depth explanation! Without prejudice. Pure and honest explanation! He’s right, he just talks about technology. Good job Mr. Gary! Tnx!

[@vms_kt]

Awesome work Gary. Good to see this much research on the hidden part of mobility :). Many questions answered here. Also why iOS uses less memory. May be Symbian too did something like this to run so many apps in parallel on such low memory.

[@Johnny-qc3fd]

Great explained I am a BSc student and learn so much from this video about how the memory is managed. Thanks!

[@bjornhalstrom9933]

I found the video very interesting..He used the RAM Truth app which makes display showing how the RAM is apportioned. The is also Storage Truth which tells how the Flash media is apportioned. If you are a developer and your app saves any sort of data you need to protect that data when your app is pushed into the background by, for instance, writing it to a cache. Any write to internal or removable storage must not be interupted or blocks in the storage will be rendered unusable. Eventually the flash memory first becomes read only and then dies. Built-in flash memory seems to usually resist this but less so with removable storage. Care must be taken to complete all the writing operations to it. If your device kills a write in progress your SD card is damaged.

[@adithyabhat4770]

I need a video about virtual memory

[@N-e.o]

All I need to know is if killing these apps is more battery friendly or let them stay cashed in the RAM Gary?

I wish I could up-vote this video twice. Oh wait, I can with my two accounts and I will.

[@chrismardz1700]

It's 2019 now. Hope these softwares or operating systems can handle apps and compressed them so we might not need more ram that is way too expensive nowadays...

[@MahfuzShaon]

your videos are the best gary. Very informative. Ive been looking for these answers for ages

[@shouldiupload24]

won't it be cool if you was able to buy more ram for your smartphone like how u go to the store and buy a memory card?

[@shouldiupload24]

oh I forgot iPhone don't use memory cards

[@fez877]

You can actually take your 32gb iphone and replace it with a 256gb internal storage after your warranty expired. Or if you're a daring enough, do it right away after you buy the phone and void the warranty. Lots of people are doing it. They even help you to port every single data over.

[@mindrover777]

Bobby Lavinier how about 199 gb

[@Abnarly]

Fez Ok that's storage but what about RAM?

[@vikrantchatole2570]

FUN FACT: iPHONES DO NOT MULTITASK! Explaination: As you press the switch to some app leaving the other app in the back ground, Android keep the whole app running in the RAM. While, APPLE IS SMART, iOS takes away most of the processing resources from the app as soon as you put it in the background. THE APP IS NO LONGER RUNNING AT ALL! Android keeps all the services, data and resources intact even when the app is in background. The app still gets its share of processor to complete what its doing, while iOS saves the app's state immediately and removes it from the processing queue, i.e. the app is not running in the background. PROOF: The proof of it can be found as you run an app that uses background processing on older iOS versions. For e.g.- Lets say you were running the Udemy app and click on the offline button, obviously you won't watch the screen till it completes downloading so you switch to some other app. Soon enough you'll find that the download has stopped, soon as you switch to udemy again, the downloading resumes. This is called Pseudo Multitasking. Apple later recognised this problem and allowed only certain services to be ran behind in the background. Only certain services, I repeat. That means the process that needs processing power in the background will have their share of the processor but only certain ones and not the whole apps. Smart move

[@ckingpro]

Actually apps can run in the background since iOS 7 in the Background App Refresh. As for the download problem, iOS can continue the download in the background or (if it is not needed immediately), it can schedule it for the best time (for instance, when the user is connected to WiFi as to not use data or if the battery is lower or based on charging patterns it will do so when the user is plugged in). Also, apps that run in the background get a lower priority (part of GCD scheduling) than foreground apps so as to not hinder the foreground app if it needs more CPU resources. Even apps that are removed in the background, if they requested the system to download a resource the system actually will. If not, they can always use Background Refresh to do so.

[@alphazar]

So it's already fixed? Ok

[@ghostryydr]

Dude mine doesn't keep the danm apps in the background. I came with 2 GB and I cried so bad

[@yvrelna]

iOS's design isn't smarter. Simpler, yes, smarter, no. Android tends to keep more things in the RAM that's why it is able to take more advantage of the larger amount of memory, and iOS is much more aggressive at suspending/killing background apps, so it won't really benefit from a larger memory as much. The main difference between Android's and iOS approach is mainly philosophical. Android leaves it to the app developer to decide whether they should remain running on the background or not, and implements smart heuristics to decide when to kill apps; while iOS takes a more heavy-handed approach to simply kill the app as soon as it is no longer foreground app. Android's heuristic have been improving every versions, while iOS have been adding features to allow more applications to run on the background.

[@Alexus00712]

**starts a flame war**

[@dbjungle]

Gary, can you do a video on if Android phones become slower over time and if so, why? I personally have not experienced this phenomenon, but a lot of people claim they have. I think it's placebo personally.

[@sudipchatterjee]

Please add some more pictures/slides and animation in these kind of presentations. Then it will be a lot easier to explain and understand. Also, one of the reasons why android cannot reduce the RSS like iOS is the type of hardware. Android runs on a vast range of hardware; whereas iOS runs only on proprietary hardware of Apple. Thus, iOS natually has that "home" advantage which cannot be matched on android platform. Overall it is a very well-intended video. People need them. Not to become experts but to keep themselves informed. Very well done, Android Authority and Gary !! 👍👍

[@chmun77]

Well Gary, if every single app is consuming more ram than apps on the iOS, imagine having multiple apps opened at the same time and the memory consumption on Android will be pretty alarming eventually. Perhaps this is why we are facing apps being terminated by Android (not after a week of course) due to low available memory? Also, I have compared the amount of available ram before on a new iPhone and Nexus. While the iPhone has ~1.6GB of available ram, the Nexus has already consumed ~1.6GB of ram upon booting up. Why is Android taking up so much memory? Is it due to its lots of background running services? Does doing swapping on flash disk will actually wear out the flash so badly? I mean, if we are using SSD now on computers, and I believe there are even much more IOs happening on a computer, I don't see SSD wearing out even after more than 2 years of usages! Furthermore, with digital cameras on the smart phones now, we are constantly taking and deleting photo files, transferring and removing music files, etc, I do not see the flash disk in my phones wearing out even after 2 years of usages as well. So, is it really so bad like you have described? Once again, nice vid there Gary. But at the end of the day, I still find my iPhone still performs much snappier and smoothly than my Android phones after using them for a long period of time. I don't even have to worry about clearing caches, killing apps from the app switcher, etc at all on my iPhone. It just work well on the iPhone - even with only 2GB of ram. "How iOS is doing that, we don't know" - this feature alone beats Android hands down because end consumers do not need to know how it is done, as long as iOS give users the better user experiences. Perhaps, iOS does make good use of memory swapping on its flash disk after all?

[@yagoa]

swapping uses a lot of battery as well pretty much a much as launching it

[@renedominguez8395]

Android apps need a java virtual machine to run, that’s the reason why android phones seem slower. For a lot of reasons I prefer iOS and even Windows Phone (only bad thing was apps)

[@juliusocasla4191]

I agree my older i phone is much faster than the new android phone i got

[@nahbicris]

René Domínguez de Santos that is true but not always, because you can program software in C o C++ for Android Java is just the most popular lenguage, also if you si bechmmarks of java are milliseconds of difference sometimes wining java.

[@moneyman64]

Android phones need more ram because it needs more power to match iphones.

[@vipulsemwal478]

Definatly!!!

[@randielrodriguez8297]

so the real problem is optimization basically.

[@fixpontt]

optimization for what? there is no such thing "optimization" in general

[@supme7558]

Yup thats what samsungs new phone are the best

[@rollmeister]

Apps need libraries. That gaming app shrinking from 300mb (or whatever) to 10mb could be due to the app going to sleep or pausing, unloading the libraries that actually do the work like graphics. Apps tell the libraries what to do, like a musical sheet offering the notes to use on an instrument. The libraries do most of the actual work.

[@sandy02]

Absolutely fantastic and detailed explanation. Good job, Gary.

Apple also uses really fast flash storage.

[@TaskerTech]

Terrible, actually macOS and iOS manages ram way better than Windows and Android, they use the resources available to make the whole system faster, and if needed they would get rid of what is not necessary atm

[@SmashDde]

Urban myth which we can't get rid off, sadly.

[@_Palatis]

Android too use the "compression" idea, it's the "zram" you saw on screen. technically it's a "compressed memory block device", everything you throw into it, the kernel compress the data, and put the compressed bits into ram, and it only occupies physical ram when there's is something inside it (a bit like a tmpfs, but compressed). this "zram" can be used as the swap partition (same idea on a desktop), so when system is running out of phys ram and user apps asking for more, it compress some of occupied rams into zram, and free up physical ram for new apps. however not every phone adopts this, tho. depends on manufacturer.

[@seethisth4753]

How did it come to this? Few years back (well, maybe more than few) I had a computer that had 256mb of ram. I could run entire system, web browser, music player an a few more programs at the same time with no apparent problems. And now, an application that displays a webpage (Facebook app) uses more than 100mb of ram?

[@joshperkins6481]

An interesting thing I've noticed about Android across four phones with four different OS versions and four increasing amounts of RAM is that Android always seems to allocate between 30% and 40% of physical RAM to the OS. Even seeing the same version of the OS on different phones with different amounts of RAM, the ratio is usually within that range. This must have something to do with system file compression, right?
