Interesting tech but there’s zero explanation of the actual application, so it’s all a little abstract.

> The real challenge was making it run continuously without iOS deciding my app wasn’t important enough to keep running

Would like to see more thoughts here

But it's asinine for developers to have to pay $99 in order to test their app, such as on TestFlight. When you have an app idea, when you are far from deciding on monetization, you just want to test out the central features of the app among friends, it's wrong to require payment for that. Remember all apps have once been low effort apps: the first few weeks when you begin working on them. Polish comes later.

They can test and iterate using simulator without spending $99

I said test among friends, i.e. potential but real users. The gulf between the simulator and TestFlight is so large that they are better considered completely different stages of testing.

Furthermore, there are so many things that can't realistically tested by the developer on the simulator.

> The phone’s battery health held up reasonably well. After over a year of constant operation, it’s at 76% capacity.

I have an iPhone SE that I've tried keeping plugged in all the time and its battery has turned into a spicy pillow three times, first with Apple replacing the whole device (since they won't touch it with a swollen battery), then using third-party replacement kits.

This isn't going to work for long if the battery is usually at 100%.

My #1 wish for being able to repurpose old phones is to operate without touching the battery, and/or keeping the battery at 50%. Newer Apple phones have an 80% limit option which is an improvement, but I'm not sure how much. And unfortunately the option isn't there on any but the most recent phones, even on up-to-date iOS.

>How much something costs is not what determines how much a company charges for something. It actually does - in a free market. That's, like, one of the main arguments why capitalism is good for the population and not evil. But in a gate-kept oligopoly like phones, actors can abuse the system to squeeze more money out of consumers, leaving the corporations as sole beneficiaries. That's why this kind of stuff usually…

I'm pretty sure in a free market, how much someone is willing to pay for something is what determines how much a company charges for something, not how much it cost to provide. We wouldn't have inflation of most goods/services if it was based on how much it cost to produce/provide.

True - how much someone is willing to pay matters. However in a competitive market, companies can’t just charge whatever people will pay. Competitors will undercut them, so prices should eventually align with the cost of production plus a reasonable margin.

Most of these devices can't run "without touching the battery" because the external supply can't provide the required peak current, so during some CPU burst it would shut off.

I've seen hacks that replace the battery with a supercapacitor though.

Interesting. I've had a spicy pillow on a 2017 MBP, they fixed the poor thing, and while at it: replaced the cursed keyboard, and left some kind of tape to reinforce the loosened USB-C ports.

Unfortunately, they didn't do the thermal paste - I had to do DIY, which is something I will never touch again. It did pay off though, it's cooler by some 10°C under load, and runs faster too. It's still loved and in everyday use.

I have an iPhone 8 still in service and compared to an equally old Android device, the Android (some kind of Motorola eX series low end phone) runs circles around the iPhone. Even playing background video or audio streamed from wifi and output over bluetooth with the screen off, the Android will burn 15% in an hour while the iPhone will burn over 60%. Both are the same age but the iPhone feels subjectively obselete while the low end Motorola feels like a mid-2010s computer. Even for it's age the Android will last two weeks in Airplane mode.

> Like, how is it even justified—does Apple really spend $99 on infra maintenance and server costs to host your app? How much something costs is not what determines how much a company charges for something. A company sets prices based on what will make it the most money. A company only lowers prices if they think doing so will generate higher total profits in the long run. Apple seems to think charging $99 a year for…

There can’t be that many iOS developers that the $99 really affects their bottom line. I always assumed it was a barrier to entry to help discourage low effort apps.

Of course there are. Many browser extensions are available for all platforms except Apple's, because you need that $99/y (and a Mac) to wrap (and fix up) a bunch of JS you already wrote and tested everywhere else.

I applaud the authors of the few good extensions who went the extra 20.000 leagues. (But I still reluctantly switched to Ungoogled Chromium.)

Plug your charger to any Homekit-compatible "smart plug," and create a shortcut that turns the the plug on when the battery reaches 45%, and off when it reaches 55%.

This will of course require a Homekit hub.
