The original original battery has held approximately 7-month. The replica I have acquired in January. Now the beginning of June, he can no longer load. Since the end of April I have problems that the battery indicator is visible in full. Following a - maybe 10 minutes - call comes the battery-empty message. Likewise, after short-term use in the email function or when trying times in between a mobile game.
On the part of Nokia battery is not currently available, I will visit the store again, and order if available (but since January is not available in a 450, - EUR phone ...). I have once again bought a replica, this time one that is marked as such, and I hope that the information is correct there, so I can assume that this is also the Originaö entsperchend Powerful.
From this battery here I am disappointed.
1. No original though as sold
2. Also in new condition he maintains much shorter than a real new Nokia battery, perhaps 20-30% less (estimated)
3. After about 3 months, the phone switches off with the battery while it is loaded at night -> it rings no alarm clock. The battery is dead, although you have plugged charging cable.
Specially recommended on business NOT.
