Given the state of technology the battery decaying wasn't the issue in my latest phones. It was performance of the device. Apps keep evolving and at some point your device just can't keep up anymore.
Went from a Moto g6 I think to a Pixel3 and now a pixel 6 pro. Batteries can be charged everywhere, CPU's can't be overclock without limits.
This! Got a YumAsia rice cooker for my birthday earlier this year and it's fantastic!
Dump rice and water in. Set it. Come home to delicious rice. I love the thing!
