Battery gauge

Postby sylvain.munaut » 02 May 2026 21:17

Hi

How does the battery gauge works on the S4 ? Is it based on battery voltage ?
I'm feeding a supply from a PSU to the battery terminal and varying the voltage doesn't seem to affect it, it always shows "full".

Same for charging, is it purely based on time or does it monitor charging current ?

Cheers,

Sylvain
