    Like the new LED lightbulbs. Buy one now and they last a year or so. I bought one of them WAY back when they were brand new and horribly expensive and the damn thing still works just fine.

    Companies can’t stand new technologies that just work. They have to build in planned obsolescence. See also: smartphones, especially iTrash that make you buy a new one every year or two because updates slow them down.

      Good ones still last a long time. What fails is generally not the LED itself but the cheap-ass rectifier in a cheap-ass case that is optimised for production price instead of heat dissipation. The fixture can also be an issue as nobody designed for heat dissipation in the days of incandescent bulbs, you might be baking those poor capacitors.

      And those kinds of bulbs will stay available because there’s plenty of commercial users doing their due diligence on life-time costs. Washing machines, fridges? Yes, those too, though commercial ones aren’t necessarily cheap. Want a solid pair of pants? Ask a construction crew what they’re wearing.

        I bought about 20 Cree bulbs 5 years ago, 15 are on about 15 hours a day. I’ve had 2 fail in that time.

        Not a bad record in my book.

        Even the off brands, IKEA, Amazon, etc, seem to last as long. They’re all in open fixtures, so no cooling issues.

      The problem with LEDs isn’t the bit that emits lights. It’s the power supply, specifically the electrolytic capacitors. Good designs either use higher quality caps, or use designs that avoid electrolytic caps altogether. Either one takes a bit more money, but the market is always in a race to the bottom.

      Long term, I think we should be avoiding traditional light fixtures entirely. It’s better to have a lot of little lights spread over an area rather than a few point sources in the room. That gives us the opportunity to separate the power supply from the lights entirely, like LED strips do.

        The LEDs will also fail from overheating. LED bulbs don’t last long in fully enclosed fixtures that were designed for incandescent bulbs.

        If the bulb starts flickering, that’s usually a bond wire failure in an LED. When the LED heats up the bond wire loses connection and it will reconnect when it cools down again. The LEDs are in series, so if one fails, the entire bulb goes out. Flickering can also be caused by a capacitor failure in a switch mode supply, but most LED bulbs use linear regulators with a high voltage series string of LEDs now, which also increases the chance of a bond wire failure.

        The early LED bulbs that cost a fortune had huge aluminum heat sinks to keep them cool. The few that I had all lasted until the LEDs got dim.

          The newer designs that use very long, filament-attached LEDs in a large helium filled glass bulb also work quite well, even in a classical light fixture. The helium filling helps with cooling because helium has higher convective heat transfer than air.

        iPhones and iPads famously get slower, laggier, and less useful as time goes on. This is not just because of its use because even resetting one will make it just as slow as before. Sure, as we move forward we get more demanding applications and such, but it seriously doesn’t seem like that scales properly with the ability of the hardware, almost like Apple intentionally builds in incremental slowdowns in each patch that isn’t installed on current hardware. It’s apocryphal, I know, but there have been so many people complaining about their perfectly good iDevices suddenly not performing like they used to even after a refresh that makes me feel like there’s at least something to it.

        And don’t get me wrong, Android phones seem to do the same to a certain degree. iDevices are just more famous for doing it.

          Hey man, I’m an Android dude for phones. Won’t even consider an iPhone as I dislike locked ecosystems for phones, but this is just not true.

          Apple supports their devices way longer than any of the major Android producers do. I can’t remember the last time my phone was supported more than 3-4 years, but my iPad was just rock solid and updated for 6 years. Replaced it because I wanted more RAM for scrolling endlessly on Reddit, but it was brilliant for everything else. My daughter still uses it with no issues today, two tears later.

          The missus’ Samsung tablet on the other hand…
          What a piece of crap, and it was top of the line just three years ago.

            Yep. Apple supports their stuff a lot longer, but it does seem like it slows down more and more every single update.

            I’m really soured on the whole portable device thing completely because I don’t like the interfaces, I don’t like touchscreen (imprecise garbage), I don’t like how locked down it is by default (Android over iOS here plus some Android devices are very hackable to the point of getting root, but still), and I hate the intense data collection and tracking these devices do to you. Even phones rooted with custom OSes still track you by its mobile radio triangulating your position.

            The planned obsolescence is just another frustrating aspect to the damn things.

              We agree on every point except Apple products slowing down significantly faster than Android. My personal experience has been the polar oposite.

              Thanks for taking the time to reply!

          In my experience iPhones and iPads are remarkable for keeping the speed up as they age.

          My iPhone 6S lasted me untill 2021, and it was the battery that was the main issue, the speed of the iOS was fine

            Like I said, it’s apocryphal and probably has other reasons (like the one you mention), but it’s something you hear all the time about them to the point where it becomes major news and there has been some evidence presented, but as I said, it could just be newer versions of software requiring better hardware, which is still a bit iffy when you have an older phone and they want you to update to software that won’t run as optimally on it. In some ways, Android actually benefits from this by just creating security patches for the life of the phone for the older version, and not updating to newer versions of Android like iOS does for old phones.

          It’s not even almost, in 2019 there was a settlement where they were found to literally be making older devices artificially slower once a newer model or two was out. Settlement sign ups ended in 2020, search Apple slowdown lawsuit.

              I appreciate the look behind the curtain but since apple was found in a court to have deceived customers and was proven of wrong doing it certainly is a bit more than just the media blowing it out of proportion or Apple actually doing people a favor that was misinterpreted. For example 3 days a week I use a phone from 2018 that was my daily driver for 3 years and needed to use it as a backup MFA device that I also sometimes stream and watch media on for a few hours a day. Updated it to the latest LineageOS and haven’t had to worry about freezing or being slow or shutting off and corrupting my shit.

              The only way to circumvent this problem is to invent a battery that doesn’t age. The person who does that is going to be a _very _ rich dude.

              or how about easily replacable batteries. yes, they can be designed in a sleek, apple-y ergonomic way. but its much easier and more profitable to make battery replacements a phone killing endeavour. this applies to other manufacturers as well.

                  agreed on the batterygate thing. ars did a pretty decent writeup on the reasons behind the CPU throttling.

                  my issue with Apple has always been their… “its magic!” bullshit. that marketing leads to more and more e-waste as other manufacturers follow the sucessful Apple marketing trend, because, you know… its NOT actually magic and batteries are consumable items.

                  “Ford, how am I supposed to operate my [insanely expensive] digital watch now [that the battery is broken]?” guess i’ll just get another one!

      Gonna downvote you here bröder and chip in with the people defending Apple’s products while recognizing that Apple did go through a lawsuit and that they did indeed participate in this shady-ass practice. Whether they still do - who knows, we live in a funny age.

      From personal experience, not only is the build quality superior but they do last pretty long. I’ve got 3 devices personally and have had experience with many more.

      My SE that’s old as hell now. I’m not gonna say it runs every app just fine, but the OS functions just fine. I use it as a music player now tho and iPhone 14 as my phone.

      SE2 was shit, I’ll admit.

      I bought M1 Air when they just came out - it has barely slowed down. Admittedly, it was after my 12 year old Acer plastic clunker decided to not wake up one day.

      I also just recently used a friend’s pretty ancient iPad for Procreate and that worked just fine as well.

      If someone’s looking for great UI/UX out of the box and great industrial design, what other alternatives are there besides Apple? At least for smartphones there are none. If someone did put a really nice feeling (physically) smartphone in front of me and said: “hey, you can switch everything off with hardware switches and all the apps you’re used to are supported plus the UI and the camera is competent”, I might jump, maybe. Depending on how I could manage my workflow with Linux bc I’m not going to Windows and in this hypothetical scenario if I’m jumping Apple, I’m jumping everything not just the phone.

      All that said, I have been giving a thought to all of this for some time and as soon as the time is right for me, I will switch, out of principle. I would love to be able to run some other OS on Apple phone hardware tho.

        And this right here is where you went from cringeworthy Apple pandering to laughably, horribly wrong. crApple iTrash has the worst goddamn interface of any system. I’d rather use pure DOS from the fucking early 90s than have to poke around on iOS’s ass-backwards interface.
