Do Apple and Google Sabotage Older Phones? What the Graphs Don't Show
Harvard economics professor Sendhil Mullainathan takes a look in the New York Times at interesting correlations between the release dates of new phones and OSes and search queries that indicate frustration with the speed of the phones that people already have. Mullainathan illustrates with graphs (and gives plausible explanations for the difference) just how different the curves are over time for the search terms "iPhone slow" and "Samsung Galaxy slow." It's easy to see with the iPhone graph especially how it could seem to users that Apple has intentionally slowed down older phones to nudge them toward upgrading. While he's careful not to rule out intentional slowing of older phone models (that's possible, after all), Mullainathan cites several factors that mean there's no need to believe in a phone-slowing conspiracy, and at least two big reasons (reputation, liability) for companies — Apple, Google, and cellphone manufacturers like Samsung — not to take part in one. He points out various wrinkles in what the data could really indicate, including genuine but innocent slowdowns caused by optimizing for newer hardware. It's an interesting look at the difference between having mere statistics, no matter how rigorously gathered, and knowing quite what they mean.
speed is about the same too. i plan to use it until it dies or i can't get any new apps which will probably be a year or so after ios 9 ships
Apple, who continues to provide updates to older phones years after they're released. Some users find these new features slow down their older phones.
Google, who doesn't have a mechanism to provide updates to almost any of their phones years after they're released. Some users find their phones slow down years after release anyway.
It is a big leap, there could be various other explanations of varying degrees of malice. As the new release comes through, bug fixes for older releases are put on back burner, apps are changed and tuned to take advantage of new version run slower in older version.. Or the way graphics subsystem is organized in iOS might have different bottlenecks based on the display resolution. So as new releases come in, default sizes for buffers and hashtables might change deep in the OS slowing down older apps.
And if you are going to postulate "Apple might slow down older versions deliberately", why can't you postulate, "Google might spike and skew the history of the past searches to make Apple look bad"?

I don't think there's any reason to read a conspiracy into the situation. They release a new phone that's much faster, and then they release an updated OS with new features to take advantage of that extra computing power. Adding features that use more computing power makes the old phones seem slow.
I'm tempted to compare it to the development of desktops and laptops, both of which went through similar upgrade cycles before leveling off a bit. However, there's a big difference in that desktop and laptops were developing quickly to cram features into the OS, at the cost of focus on efficiency, which serves as a partial explanation as to why things became "slow" with upgrades. Desktop and laptop software went through a period of bloat, and then in recent years, additional features traded off against speed gains from recoding things with efficiency as a goal. Meanwhile, Android and iOS needed to be written to be efficient from the start. They wanted to make the hardware as small/thin/light as possible, which meant that the power requirements had to be low. To give an example of the effects of this, a requirement for using as little power as possible has been the reason iOS has always limited multitasking.
It is a bit strange they did not correlate to iOS releases, but iPhone releases.
I find it much more likely that when you upgrade to iOS+1, the new features slow your phone down. I've experienced that several times, my 3GS became "much slower" after upgrading it. The new iOS had more eye candy etc.
But that's not the same as saying the old hardware is slower.
Probable impossibilities are to be preferred to improbable possibilities.
Aristotele
The article says, "phones feel slower over time as they hold more software". How does this follow? How does the phone get "slower" just because more software is installed? This sounds an awful lot like the cargo cult thinking of "well the hard drive is full so we have to buy a new computer because this one is slow."
I know some software will start agents on boot, but they just sit in the background and do little. top reveals very little CPU time and memory consumed by these.

The methodology of testing the hypothesis is to look for google searches about "iphone slow" or "samsung slow". Assumption made is if people search for "iphone slow" Apple might have done something to slow down iPhones. The control group is Samsung which has the same motive as Apple but not the means because it does not control the OS.
Actually, the data was gathered to see if the professor's view that his phone had slowed down was also shared by other iPhone users; they found an interesting correlation between search spikes and new iPhone models but were careful to say that doesn't prove anything other than people perceive a slowdown when a new phone comes out. He points out some valid reasons why the Samsung / Apple data differs, primarily that Apple releases a new version of IOS with the new iPhone and thus the new iOS may not be optimized for older hardware while many Android users remain on an older version. In addition, since the Andriod device makers don't control Android they may find it cheaper not to spend a lot of time on the OS and rather invest in hardware improvements as the differentiator.

When the old firmware has security issues like the Apple SSL bug it is a bad idea not to update the firmware.
I do suspect they do not even bother compiling the binaries for the older architecture by switching a couple of compiler flags though. The performance difference is just too big.
Yeah, come to think of it, my washer is a lot slower these days......
Well your suspicion is incorrect. There is a separate build for the OS for each supported device. If you download the OS on the computer from iTunes you have to download a copy for your specific device.
I've noticed the same thing about my body. Damn you, Apple!
You are welcome on my lawn.

There's another problem with his theory as well; as we all know, Android phones don't get many OS updates, if any at all. Every study that checks (using real methods) the Android versions currently in use based on hardware, vendor, or general population finds that unless you bought your phone very recently, there's almost no chance you're running the latest version of Android. So how is it that Google is managing to slow down old phones with code in the new versions of Android in the first place?

The concept is called planned obsolescence , and it has existed for as long as people have been buying things.
In the end, the professor, after writing thousands of words, comes to no conclusion.
He's an economist. That's his job.

The question though is whether they're instructing the compiler to *optimize* for each target platform, or if the only difference is the drivers, etc. included for the different hardware.

Studies have also shown that as humans age their rate of recall also slows down, not because their brains are slower but because they have to navigate a database filled with entangled excess information. I've noticed that google searches by voice are vastly more word-accurate than siri searches by voice. But that's because google is doing something in the context of something else-- it has clues to context. Siri is trying to do free-form semantics over a much greater realm of possibilities. When you narrow Siri to a phone specific function, it does better than google. As the AI realm grows, perhaps to include sarcasm and slang, these services will require even more compute power to keep going.
However, these days, phone services are done on back end servers, so there is no great reason they should slow down in "modern" times.

My 2012 Nexus 7 was getting unbelievable slow, then I did a factory reset and it was speedy again. I, also use tools to tweak what programs run at start up, which has helped a lot, too.
Do you really think they are so incompetent that they have a different build setup for each device and not have different optimization set? We know they have some different flags set because it has to be built for both 64 bit and 32 bit chips.
So you're bragging about Google improving the very bad Dakvik engine after 7 years and you're comparing that to iOS which has been completely compiled to native code since day?
Google has been promising 60fps animation for 5 years -- something Apple did in 2007.
Exactly! The methodology is incorrect. And, after having spoken with the good people at AT&T (that's right, buy at the sign of the Death Star) it is the Telcos that are responsible for slow-downs, not the telephone makers.
Why? The Telcos want you using the latest tech so that you will have a two-year contract with them that you cannot easily get out of without paying them lots of money. This keeps you "loyal." And it gets you on the treadmill of upgrades that ensures your loyalty. So what the telcos do is that they "sunset" technology that supports the older phones. And all of their upgrades on their cell towers (which usually aren't really towers that much any more) support new radios and signaling, not the old stuff.
So blame Apple and Samsung all you want, but it's the Telcos that are responsible for slowing down the older tech, not the manufacturers.

Hypothesis one: users' irrational fetish/honeymoon-glow feeling about their old phone is brainwashed away by the advertising for the new phone model so that they're better able to perceive its slowness relative to laptops that cost the same amount.
Hypothesis two: users aren't searching because they suddenly think their phone is slow. They always thought their phone was slow, but before there was nothing they could do about it. They're searching for reviews comparing the speed of new and old phones, to see if there's really an improvement.
Hypothesis three: Apple and Google are somehow slowing down the phones without pushing software updates to them (since, except for Nexus, Google isn't even _able_ to time software update pushes).
Possible journalist approaches: measure the speed of the fucking phones. Ask users why they were searching with a poll on the landing page for the search. Conduct a web poll trying to distinguish hypotheses one and two, shortly after the release of a new phone. Ask Google and Apple if they are slowing phones down, and if they have any historical phone speed measurements they would like to share so you don't have to do it yourself.
To write the actual article: delete hypotheses one and two, then say "I have no evidence to confirm or deny [complicated hypothesis three scenario] but let me explain how it would work."
Fuck this guy. Google and Apple deserve, and desperately need, better criticism than this.
It's not necessarily a different build setup, provided the basic architecture is the same (e.g. all ARM, all MIPS, or all X86); build once for your base architecture, then package apps and drivers per-device. Yes, Apple has a 32bit build and a 64bit build, but that doesn't necessarily mean they build for every device. What's really being asked here is whether builds are being targeted for specific devices, or whether a single build is being packaged for multiple devices.
A question worthy of being asked, rather than assuming the answer and looking down an anyone bold enough to realize the question actually deserves to be asked.

My smartphone (Samsung Galaxy II) started running slowly. Even after I removed all the unused apps that I had downloaded, movies and photos, it was still running slow. Then I started looking through every single folder. It seems that the trash-cah wasn't actually emptying, and that there was a directory called ".faces" which seemed to archive every single picture that the AI software thought was a face. After those files were removed, my phone regained it's original speed.

I had the same problem, after rooting it I noticed plenty of Gb of log files, which I deleted. But the phone kept getting slower after each update so I installed CyanogenMod and it got a 2nd lease on life.
