Rate from buying dringenst from!

I advise the purchase of this battery (sold by invero) dringenst from!
The battery lasts in my Desire grade once 13 hours.
It is thus still significantly worse than the worn original battery.
The original battery lasted for about 2 days early. The battery life decreased until the end of about 20 hours.
The new battery will last under the same conditions, ie similar without new apps were installed, grade 13 time hours rather even less !!!
Have now first the old battery reinstated so that a 20-hour operation I is at least possible again.
Like the other reviews come about, is beyond me !? In my opinion, it may be just to other batteries or there are Fakebewertungen!
