My battery I bought at cellephone. The delivery was very fast and the battery is just under 9 very favorable. The batteries are different to my first original battery only in manufacturing date. Appearance, stickers, writing, everything is identical. My first battery is now 2 year old and should be replaced. Has experienced my S3 through the updates me the reduction in capacity is not particularly noticed. Finally, the OS has become more energy efficient over the years. The mobile phone now holds considerably longer as before. Absolute recommendation.
