Have the battery for a year now in use. Initially, the power was still perfectly fine after about half a year but took this from (min 1 time charging per day) and now (after 1 year) the battery is defective. My S3 mini peels often for no reason off and on again and remains only switched to the charger for a short time until there occurs the problem. When you insert a battery pack other problem was no longer present. And it's too late to send in it to guarantee. But the battery lasted for a year so 3 stars.
