Calculators are kind of a special case. When you are not pressing a button they are doing literally nothing, and maintaining the state of the LCD takes only microwatts.
They use so little power that many "solar" calculators are fake, the "solar panel" is decorative only and a hidden button cell battery provides a decade of battery life: https://youtu.be/uLTDuGhqE2w https://youtu.be/uLTDuGhqE2w
- swagasaurus-rex 4y agoMy childhood would have been so much more boring if I couldn't starve my calculator of light and watch the screen get dim
- astura 4y agoIs fake solar powered calculators a new thing or am I misremembering my childhood? I remember entertaining myself[1] by covering the solar cell and watching the screen go blank. Edit: nvm, YouTube comments and even a sibling comment to this mentioned the same thing, my childhood memories are real. After watching the YouTube video the guy took apart five calculators and only 2 had fake solar cells, so not what I expected. [1] yeah, pre Internet entertainment was boring in comparison.
