  • The main thing (by far) degrading a battery is charging cycles. After 7 years with say 1,500 cycles most batteries will have degraded far beyond “80%” (which is always just an estimate from the electronics anyway). Yes, you can help it a bit by limiting charging rate, heat and limit the min/max %, but it’s not going to be a night and day difference. After 7 years with daily use, you’re going to want to swap the battery, if not for capacity reduction then for safety issues.


  • I think I have a simple function in my .zshrc file that updates flatpaks and runs dnf or zypper depending on what the system uses. This file is synced between machines as part of my dotfiles sync so I don’t have to install anything separate. The interface of most package managers is stable, so I didn’t have to touch the function.

    This way I don’t have to deal with a package that’s on a different version in different software repositories (depending on distribution) or manually install and update it.

    But that’s just me, I tend to keep it as simple as possible for maximum portability. I also avoid having too many abstraction layers.



  • Technically, wired charging degrades the battery less than wireless charging, mainly because of the excessive heat generated by the latter. The same way slower wired charging generates less heat. Lower and upper charging limits also help (the tighter the better).

    But I personally don’t bother with it. In my experience, battery degradation and longevity mostly comes down to the “battery lottery”, comparable to the “silicon lottery” where some CPUs overclock/undervolt better than others. I’ve had phone batteries mostly charged with a slow wired charger degrade earlier and more compared to almost exclusively wireless charging others. No battery is an exact verbatim copy of another one. Heck, I had a 2 month old battery die on me after just ~20 cycles once. It happens.

    Sure, on average you might get a bit more life out of your batteries, but in my opinion it’s not worth it.

    The way I see it with charging limits is that sure, your battery might degrade 5% more over the span of 2 years when always charging it to 100% (all numbers here are just wild estimates and, again, depend on your individual battery). But when you limit charging to 80% for example, you get 20% less capacity from the get go. Unless of course you know exactly on what days you need 100% charge and plan your charging ahead of time that way.

    Something I personally could never be bothered with. I want to use my device without having to think about it. If that means having to swap out the battery one year earlier, then so be it.










  • I always hear power efficiency as an argument that ARM chips are magically better at, but Ryzen AI 300 and Intel Core Ultra 200V series seem to be very competitive with Qualcomm’s offering. It’s hard to compare 1:1 as the same chip in different laptops can be configured very differently in terms of TDP and power curves and the efficiency “sweet spots” aren’t the same for all these different chips. Core Ultra 200V is also awaiting more thorough testing, but it seems to be right up there with the Snapdragon.

    I honestly found the Snapdragon X very underwhelming after all that marketing of how much better it was than Apple’s M3 and Intel’s and AMD’s offerings. By the time the Snapdragon was actually available in end-user products, AMD’s and Intel’s competing generations were right around the corner and we’ve also seen a vastly improved M4 chip (although only in an iPad so far, so meh). Add to that the issues that you’ll encounter because while Windows’ x86 to ARM translation layer has certainly improved, it’s nowhere near as seamless as what Apple did.




  • I was surprised until I saw the spec sheet. The A17 Pro in the iPad mini has a 5-core GPU as opposed to the 6-core GPU the iPhone 15 Pro has with the chip.

    So the iPad mini features a binned version of the A17 Pro chip, and Apple likely has quite a few of them piled up as they only ever sold fully functional A17 Pro chips so far. The N3B process didn’t have the best of yields to chips with partial defects would’ve likely been quite common.

    Combine that with the likely lower volume sales of the mini compared to larger iPads (and obviously iPhones) and Apple can probably sell the mini for a couple of years without needing to produce new A17 Pro chips.

    So it actually makes a lot of sense. Makes me wonder what they’ll put in the next regular iPad though.




  • Best case is that the model used to generate this content was originally trained by data from Wikipedia so it “just” generates a worse, hallucinated “variant” of the original information. Goes to show how stupid this idea is.

    Imagine this in a loop: AI trained by Wikipedia that then alters content on Wikipedia, which in turn gets picked up by the next model trained. It would just get worse and worse, similar to how converting the same video over and over again yields continuously worse results.
