After three full discharges loads I am fully satisfied with the autonomy of my Galaxy S3. Two and a half days and two nights in daily using some internet browsing, listening to the radio and some TV, some videos, emails and press releases. No more searching for an outlet. This requires a good battery management. While the baby has gained weight and thickness, but as I have big hands, but rather an advantage. For more protection against such flip cover. It must go through the universal cover. You can not have everything.
