I never had issues on froyo or stock GB, nor on cranium 3.1 (kph) or cranium 5.1 (kpq). I only had it on cm7. thanks to this thread, I discovered I forgot to uncheck background data, and just to be sure, I also deleted the backup transport. I then recharged my phone and reset it to clear the current stats. my stats at the moment are:
95% battery remaning after 4 hours
39% used by cell standby (1.95%)
30% used by android OS (1.5%)
16% used by phone idle (0.8%)
9% used by display (0.45%)
5% used by voice calls (0.25%)
3% used by andrpid system (0.15%)
so OS is still being a hog at the moment.
i9003 flashed to GB 2.3.6 (KPQ)
, rooted and deodexed
, and overclocked (uc v5t6) cranium 5.1 thanks to the hard work of many people!
now we just need rex4u to get his health back so the ultimate i9003 ROM could be completed!
for those flashing custom ROMs, calibrate your battery!!!
for those familiar with calibration seeking a faster calibration, try this
