After a week of use, despite some misgivings I am happy with this battery. Samsung received in packaging identical to the photo, and above all, I was afraid that my phone is the end of life, this battery has risen! Rest easily loaded 24 without too much stress of course, finally as with the original battery. FYI the old discharged itself after 30min ignition and without using internet or apps. I had to keep it permanently in charge, now I found his cell function :-) :-)
