CR2032 vs LIR2032 vs Capacitance Battery
I have installed CR2032 in one of the other Android device that I have. It has been working fine for about 10 months now but I highly doubt it will last for 3 to 4 year though.


Why? The RTC should only require about 1 µA, which is in the same order of magnitude as the self discharge rate of a CR2032 coin cell. You can expect it to work for about 5 to 10 years - depending on the quality of the cell itself, so YMMV.

LIR2032 may have too high a voltage (4.2V fully charged), and both LIR2032 and capacitor need charging circuitry.
