As asked in title, can anybody answer? Could raspberry be made equally poweroff resistant as an android phone to which battery is unexpectedly removed?
It would be so great to have a rpi power cut resistant!
Long story short, smartphones and other devices have an internal memory different from SD cards. The technology is supposed to be failure proof. The SD card in another hand is built to be cheap.
If your Android is using the micro SD while you remove the battery, it might corrupt the card as well. Also, the firmware of your phone is stored in a read-only partition in the internal memory.
