I've found it remarkably difficult to replace a battery in a modern smartphone, even as someone who's quite handy with electronics. Any improvement is greatly welcome, and I wish we'd do more to make it easier.

It's about usage patterns. If you know you only need 60% of the battery, charging it to 100% will degrade it more, for little utility. The newer Google phones get 7 years of updates, but without due care the battery will reach 80% of its capacity before that. On an aside, a battery is considered to have reached its end of life at a capacity reduction of 20%, and not 40%.

If you 100-0 the battery every day, then there's not much you can do. But if you're a lighter user, then using the 20-80% (or 40-60) part instead of the 40-100% part of the battery makes it last longer. And that's good in terms of environmental sustainability, reduction of e-waste, and you can use the phone for longer, too.

Pragmatically speaking, for battery health you should charge only as much as you need the battery, so it sounds to me that in your case that's 90%. Also, here's a paper about battery charging:

Funny thing is, now that I have it I keep finding uses for it. Sure, some of it is "well I've got it now so why not?" but I didn't expect a handheld pc of this configuration to be so handy to have around.

Almond milk is almost as cheap as dairy here, hopefully it catches on more.

The Center for Scholars & Storytellers (CSS), based in the Psychology Department at the University of California, Los Angeles, designed Teens and Screens to investigate American adolescents’ perspective about the media they engage with and consume. This yearly study aims to elevate the voices of adolescents, hoping to have an impact on the media landscape that’s a part of their daily lives. We are grateful to the Funders of Adolescent Science Translation (FAST), the Walt Disney Company, and Roblox for their support of this independent research.

Specifically, American teenagers.

It's fine, the export controls are good because they make China more self dependent. Their chip designs also improve because of that!

I quite like the crust, but could you not slice the crust off? That would likely improve the bread to crust ratio considerably.

Do you mean to say that this achievement had something to do with AI?

Looks like pure mathematics to me.

I'm sure the Russians are savvy and use VPNs like China. It's much less simple than just geofencing.

When it happened to me I was so scared I cried. I went to see my therapist, who told me I was shedding tears for fears.
