I have one of my Galaxy S SCL bought autonomy problem there is almost 6 months special offer at Auchan. This problem appeared suddenly there 2 months. Replacing the original battery 1650 mAh battery with a 1800mAh POLARCELL has neither solved the problem nor improved the autonomy of my Samsung GT 19003. The difference posted capacity is too small to notice a difference in autonomy. It seems that the problem comes rather a possible decline in transmission power of the telephone relay, which causes as a specialist on consumption due to automatic search connection to my network operator? That remains to verify and measure very soon I hope by a consumer association or a technical journal etc. Hafid
