You're likely right. Some stable power feeder does need to exist, but could it skip the chemical energy storage parts?

The charge-discharge cycles needlessly put a lifespan on that component when I'd like to have it left on 24x7.

Same for always-powered laptops. With WFH, for 1+ year I've used my Thinkpad as a desktop, not bothering to unplug when fully charged, and now the battery doesn't hold charge for 10+ mins.

The answer is that phones really need a user setting to enable a charge limit.

About 4 months after COVID hit and I started to WFH, the battery in my Pixel 3 started to swell because I had allowed it to basically live on the charger all day, constantly at 100% battery. Also, by that point, a 100% battery would only give me about 2 hours of screen time.

A few months ago, I got a Pixel 6 Pro, and I'm basically just charging it from a weak 500 mA USB port a couple hours each day, keeping the battery between 50-80%. I'd really like to set an 80% charge limit and just forget about it.

AccuBattery gives an audible alert when a configurable charge level is reached (default is 80%). Not as nice as having the phone stop charging by itself, but at least I'm not frying my battery.

I don't think that's normal. I have an old cheap Lenovo from 2012 that sees 4-12 hours of active use daily. It's almost always plugged in without any limits on the battery charge (which as a result is always at 100%). The battery still has around ¾ of the original capacity (it ran for ~4 hrs of light use back in 2012, and gives around 3 hours now).

I don't think it can. UPS's store energy too, and stop holding charge after a while. It would be nice to bring back easily replaceable batteries, since they're basically a consumable these days.

I don't know anything about how much "oomph" a dashcam needs as opposed to a smart phone or an uninterruptible power supply but I kno0w one of the bullet points in the marketing of the dashcam on my car was it uses a small capacitor as opposed to a battery and therefore it is safer to use it in a hot car.

[Sohcahtoa82]

Yeah, but how much can that capacitor do?

I had a dash cam years ago that had a capacitor, and all it really was for was to make sure the camera could finish a write operation and close the video file gracefully to avoid corrupting the last segment. Cameras with batteries often can support recording even while the car is off without draining the car's battery.

IMO, the solution to the battery-in-a-hot-car problem is to have the battery be an in-line part of the power cable that can be placed in the glove box, outside the direct sunlight, rather than building it into the camera itself.

I think some Thinkpads (P51 at least) can be set to not exceed 80ish%, but I don't know if that can be done from Linux.
