The person I responded to only has one device. But even if there were multiple devices, you could just have a smart switch per device.

The fire hazard issue is that holding the battery at 100% increases the internal chemical stress on the battery, and increases the risk of thermal runaway. So keeping it well below that will definitely have significant benefit. Ideally, trickle charging it at around 50% would be best for almost eliminating further strain. (But you’ll likely need to charge it from 20-80% occasionally to help the battery management system keep calibrated.)

And things can be done even smarter. Like only charge the battery at the coldest part of the day, typically early morning to reduce heat stress. Or throttle the device if it’s temperature reaches a threshold. Etc.

Yes, if you can remove the battery, that’s helpful. But keep in mind you lose the benefit of battery backup during mains failure.

Also, mobile phone fires get a lot of media attention because “drama,” but they’re not the hazard everyone thinks they are. You’re far more likely to have a house fire from rodents chewing into electrical cables, clothes dryer lint catching fire, or anything with a heating component. Ebikes and escooters are far more likely to catch fire than phones.

The point is if you’re not emptying your dryer lint filter every use; if you’re not getting home pest inspections every six months and putting down rodent traps or baits; if you’re not getting your heating-element devices professionally checked regularly; if you’re not storing your ebike well away from flammables; etc., then worrying about phone battery fires is ridiculously out of proportion.

I’ve got a colleague who says she’ll never buy an electric car because of the fire risk. But then she drives around in her gas car which is 8,000%+ more likely to catch fire.

If you’re still paranoid, keep the device in a non-combustable container away from flammables, and near enough to a smoke detector. It’s easy to setup something that if the phone catches fire it’ll just burn itself out.

At all? What do you believe the fire hazard is then?

Use a smart power switch.

Battery level drops below say 20% - turn switch on and start charging.

Battery level goes above 80% - turn switch off.

For Android, you could use something like the Tasker app to do the monitoring and switching.

Huh? Even if it’s produced in Denmark, how can some of the revenue not be going back to the US where Coca Cola is based?

Edit: Yep, Carlsberg Danmark pays royalties and licensing to The Coca Cola Company in the US. They also buy the syrup concentrate from the US (or its subsidiaries).

So it is most definitely a US product that is being “finished” in Denmark, with a lot of revenue going to the US.

Or your neighbour does all the work instead of you, so you decide to buy soap from them. They’re next door, while Walmart is across the county line, so you decide you won’t charge yourself the extra self-tax with your neighbour.

Walmart"s soap, which used to be $2, is now $3, while your neighbour’s soap is $2.50.

A week later your neighbour sees that demand for their soap is huge because everyone is self-taxing. So they raise their price to $2.95 to make extra profit.

In case you think this is just a contrived fiction, this is exactly what happened to many goods, like solar panels, with Trump’s first-term tarrifs. Americans paid over double the average world price for solar panels.

Worse still, Trump knows this happened, yet somehow this time will be completely different. <sigh>
