I'm using the Adafruit 3295 PCF8523 breakout module in a project with a Pi Pico running MicroPython.
I just fixed an issue that was driving me nuts - it was losing the hour and year when it lost power (new battery was installed). The problem was that although the chip is designed for battery backup - It isn't enabled by default!. Turned it on (ie. set bits 5-7 of register 0x03 to 000) and all is well.
Anyway, this won't be an issue for anyone using the CircuitPython driver, but for anyone else, I hope this helps.
