It's not great news for my old phone used for wifi at our guesthouse (let's a few security cams and our smart lock get online)

Same here, using several old androids as hotspots here and there. They stopped receiving updates long ago though, so I'm not worried.

They stole the idea from GrapheneOS and shipped a barely half-baked version with hardcoded time. GrapheneOS has configurable time for it since years

I'd claim that Microsoft pioneered this time limit security concept with Windows 95 almost 30 years ago.

They went with 2^32-1 milliseconds or about 49.7 days.

We don't talk enough about Microsoft's strong legacy of security innovations, IMHO.

> ...the new Play Services will limit that exposure to three days, even if it's plugged in.

This will be fun to track down after a long weekend in embedded devices once this android patch number is old enough to be baked into crappy payment terminals and mall kiosks.

Probably overall a good thing though.

« This actually caused some annoyance among law enforcement officials who believed they had suspects' phones stored in a readable state, only to find they were rebooting and becoming harder to access due to this feature. »

Wouldn't the phones run out of battery after a few days anyway? Or do they keep them plugged in?

It's good to have an option like that, even being a default, but there definitively need a switch to disable that if it is your own will. It's not even necessarily that good enough against cops, because in a lot of shitty countries, even some pretending to be democratics, not disclosing or at least inputting your password might be a crime severely punished. If I'm not wrong, there was a guy that had to stay years in…

I don't get the difference. Today after 72 hours (3 days) my phone asks me for my password and won't accept biometrics. Also, this is a problem for all the people that use them as alarm clocks. I use Alarm Clock Xtreme for example.

Not bad. If I could make a feature request it would be something like, After 3 days of being idle: - [ ] Reboot - [ ] Power Off - [X] WIPE triple opt-in Maybe there is a custom phone OS for this that makes the phone act more ephemeral and network boot off my self hosted iPXE/immich server? A dumb smart phone so to speak. An ephemeral diskless phone.

A wipe seems extreme. An unexpected trip to the hospital could leave someone with a wiped phone when they come to.

Earlier quoted context omitted.

It's very clearly explained in the article.

It is not clear to me at all why the ‘benefits’ presented outweigh the negatives (which is _my_ device doing anything without me instructing it to). Even if you can turn it off, this is apparently enabled by default. Law enforcement keeping hold of my phone for 3 days is simply not a realistic problem for me. Coming back to an annoyingly locked phone after forgetting it for a weekend very much is. The chances of law…

That's what cops and spooks would like to have you think.

This is not not the question you originally asked. Indeed it's a much better question.

This is super annoying on newer iOS for device that I use purely for development. Before it was possible just keep iPhone unlocked indefenitely, but now it reboots and boom I have to use TouchID again. This is again Apple being Apple making things harder without option to disable it even when development mode is on. Has anyone found a way to bypass it?

I was thinking this would be the final death knell to using an (unrooted) Android phone as a cheap home server. But then again, not sure if that was even possible before with all the "battery protection" logic built into Android.
