Remember when light bulbs used to last decades? A phone battery that lasts that long is incompatible with capitalism.

When they were really dim and far too red like 80 years ago? Or when they switched to LED and actually lasted a decade, like now?

Batteries that last a decade will open up the opportunity for expensive tech like we never imagined.

Or when they switched to LED and actually lasted a decade, like now?

LEDs with Edison screws on them don't last that long. Maybe Siemens or some other brand name manufacturer, but the cheap Chinese ones last only a few months.

It's the heat buildup that's the problem. Disassemble them, slap a CPU heatsink on it and yes, they will last forever.

Seems like a manufacturer problem. I've have the same LED bulbs in my house for 5 years plus with no replacements. Various makes too .Some of them came with me from my old house. No idea how old they are. With incandescent bulbs, I used to have to replace at least 1 a year. I used to keep a stock in the back of a cupboard.

The problem with led bulbs is that they are build to operate at their limits. It's still within spec, but just barely which is why they break so quickly. If you would reduce the current by half they would last for decades.

But of course Big-Light doesn't want that, so after the initial well-build led bulbs became standard they switched to cheaper designs with less internal led modules for the same brightness.

I'm at 5 years with 12 that are on about 16 hours a day...

The battery is not the main point of failure in contemporary phones, especially not one that makes you buy new unit. This new radioactive battery doesn't change much
