Since yesterday my galaxy s3 by Sprint has been charging very slow. I've used the same wall charger for over 5 months with no issues until yesterday. So yesterday my phone was on 1% so I decided to just turn it off instead of letting it die. I got home to plug the phone up and noticed that it now loses battery life when I'm on it while its plugged in. It'll have the charging icon but it will only lose charge or stay at a percentage. I was told the s3 has a defective charging issues by a rep yesterday too. Anyways, the charger I've been using doesn't work anymore and now the charging and non charging icon comes on and off. Any ideas as to why my phone is charging VERY slow now and why my original charger doesn't work anymore?
