Thanks worwig and funkylogik for the info. I just found my old wall charger for my mytouch 4G and now there's no problem with the charging. I guess my stock s3 charger crapped out lol
My S3 used to charge from 10% to 100% in about 2-3 hrs with the stock wall charger it came with. Now from 10% to 40% in 4 hrs. Can anybody tell me what could be wrong?
