Ziko link you are not telling us how and what you cleaned. The first thing I suggest is that you disassemble the phone using [[Topic:iPhone 4S#guideList|these guides.]] Then clean the phone with +90% isopropyl alcohol. Use [guide|5825|this guide] to clean it. After you have everything properly cleaned, '''replace the battery''' Reassemble your phone and re-evaluate. Once you do all that let us know what you found out. Hope this helps, good luck.
