After 4 weeks of use, alternating with the original battery, I can now announce here in good conscience that a maximum of 50% of these battery - 60% of the capacity / service life of the org. Samsung batteries deliver. The given 2,600 mAh are therefore lied smoothly !!! Everyone should decide for themselves if the presented here performance justifies the price you wanted. I have certainly now ordered an original battery as a backup and use this "thing" here now only as a backup for the backup.
