I have a Galaxy S3 with CM 10.2 build date 28-09-2013.

The problem I am facing is slow charging of my mobile. It takes around 6-7 hours to charge when connected to AC power source. Before CM with S3 stock rom, it used to take around 3-4 hours to charge 100%.

I tried searching on CyanogenMod forums, but couldn't get an answer on how to fix this issue. Does anybody know how to fix it?

Do you keep wireless or any other communication networks on while charging? This can slow down the charging process.

  • my cell wifi is always on. I will try disabling that while charging

I've noticed that changing the charger works in a few cases. The standard charger sometimes doesn't play nice with custom Roms.


I've had this issue too from time to time, at one stage I had to turn my phone off to get a decent charge, I found that using a USB cable can slow down the charging time but as you mentioned your using a AC Power Source. How I resolved mine was buying a new battery, my battery was dated for 2012 and simply needed to go. New battery resolved my problem, and are fairly cheap!


I have the same issue. I solved it by installing boeffla kernel and turning on ignore unstable power.
