10% / hour is not an acceptable charge rate. Mine charges much faster than this.
If you are charging via the USB cable, make sure to use the wall adapter instead of plugging it into the PC and check the results. Charging via the wall is usually much faster than by using a PC's USB port.
You can do a nandroid backup of the entire ROM and then install stock to see if the ROM is the problem as well.
If you try those things and it still charges that slowly, then there is something wrong with your phone.
This is not the first thread where I heard about charging issues with people who use the nokia wireless charger. Did you have this problem when you first got the phone?
Wireless charging is the slowest method, so expect it to be slower than by PC or wall cable. The LG wireless pad says about 4~ hours for a full charge (which is still much faster than 10%/hour)...
