Certainly no genuine Battery

Have ordered two batteries and unfortunately had to retract. One of the two batteries has stopped working after a week.
Both never lasted longer than four hours, my original Galaxy Note battery keeps longer.

- Batteries are lighter than the original, which has favorable composition of the battery
- The Läufzeiten have never held more than 4 hours
- The positive initial evaluation is very implausible that buyer weighs from its battery and compares it

I was fully disappointed by Amazon in the case
