1 more, when i remove my battery, and replace it , then i charge in off condition , no matter how long i charge my phone, its stuck on 1\4 icon (maybe 23 %)
crazy..... sorry maybe i cant really help you
/data/system --> its in root directory the 1st directory (" / ") on phone, just use a root explorer. the battery calibration app does the same. (delets this file)
okay good. if on other rom you not have this bug, its good.
so we can say battery is fine & also your hardware.
im pretty sure its rom (maybe installation going wrong.) bug or some other weird problem....
but cant say anything because its confusing.
also you say that battery calibration app no work on the other rom...... you can try to delete the batterystats.bin file (this is what your battery app do if charged to 100%) maybe it helps... (hope best for you)
if nothing helps on this rom, you can try a fresh install (FORMAT /data /system /cache from recovery & install rom + gapps) & maybe you also need to a flash a stock ICS.ftf with flashtool first, then install rom. it solves sometimes weird bugs.
anyway good luck to you to solve this problem
