I have a annoying problem with my beloved 9505. The charge current changes each time i plug the charger in and out. I've tried with the stock cable and with my n10 cable. I have to plug it in and out until it hits 1200 mah (the highest I can get) - i were able to hit 1900 some time ago (after switching from the n10 cable to the stock), but then i began to act up, like the n10 cable did.. and now it's really annoying! Is it a defect charger port? Maybe it needs a cleaning? I wasn't able to find any info on others with this issue.
