In my experience, Buzzing in electronics means there's a short somewhere...does the phone also get warm or hot while charging? Check all your connections to be sure that nothing is contacting something it shouldn't be. It sounds like you have a bit of a custom job here, did you solder onto the battery tabs of the logic board/anywhere else in the phone? If you did, make sure those solder points are protected from contacting other parts of the phone. I have to ask, why are you charging an external battery? Is it being used in lieu of the internal battery? Is it the same capacity and voltage as the internal battery? If you're using the external battery as a primary and singular power source, you may have stressed and damaged the charging system if the battery is not VERY similar to the stock battery. Are you using the battery as a supplement to the internal battery? If you did, again you have to have a very similar battery to the internal one AND you have the additional challenge of needing it to be wired right. If you wired the batteries in series you are over-volting your phone. You need to be wired in parallel for this case to work...but again you run the risk of really stressing the charging system.
